Title: SCIENCE INQUIRY KITS AND TEACHER PREPAREDNESS TO TEACH SCIENCE AS INQUIRY IN ELEMENTARY CLASSROOMS.
Creator: Clayton, Angela, Jeanpierre, Bobby, University of Central Florida
Abstract / Description: The National Science Education Standards (1996) indicate that science education should include inquiry instruction. Many teachers still struggle with how to implement inquiry in their classrooms and a lack of high quality inquiry-based instructional materials has been posited as a hindrance.

Show moreThe National Science Education Standards (1996) indicate that science education should include inquiry instruction. Many teachers still struggle with how to implement inquiry in their classrooms and a lack of high quality inquiry-based instructional materials has been posited as a hindrance. The purpose of this qualitative study was to observe the instructional practices of three elementary teachers when using an inquiry-based science kit program in their fourth grade classrooms. Teacher practices and their attitudes towards their preparedness to teach science with the support of the curricular program were examined. Data were collected through pre/post survey comparisons, observations, and a focus group session. Results indicated that these teachers' attitudes were positively impacted. Teachers' access to science kits provided resources which facilitated more inquiry experiences with their students; however, resources alone did not fully address teacher science content needs.

Show moreThe purpose of the study was to examine college science professors' beliefs regarding the use of inquiry in the college science classroom, how these beliefs impacted their instructional choices and how these beliefs were enacted in the classroom. Additional questions were how teachers' beliefs vary across institution types (community college, private, four year college, and large research institution), and how beliefs vary across disciplines (life sciences and physical sciences). A case study design was required for this study due to the complexity of the topic and different data sources needed to answer the fore stated research questions. These data sources included surveys, interviews, classroom and laboratory observations and written records such as laboratory activities and syllabi. Twelve college professors at three different institutions; large research institution, small, private four year college and community college were interviewed. In addition to interviews, classes and labs were observed, a questionnaire on the five essential features of inquiry was given and samples of labs and syllabi were obtained. A laboratory coordinator was also interviewed as she was responsible for the laboratory section for two of the professors at the research institution. All schools were located in the southeast United States. The perception of inquiry by college science professors has been found to be a barrier to the inclusion of inquiry in college classrooms and was supported in the current study. While the professors described constraints to inquiry such as large class size, lack of time, disinterest of students, and lack of equipment, these limitations were due, in part, to the professors' incomplete view of inquiry as what researchers do. This view was most pronounced with the professors at the large, research institution. At the research institution, observations in the classroom mirrored the beliefs of inquiry. Lecture was the primary instruction in the science classroom, and the labs were scripted and shown to be "cookbook" with little or no evidence of inquiry noted in the labs obtained. There was more evidence of inquiry at the private four-year college and community college than at the large research institution; what was observed in the classroom mirrored what the professors believed about inquiry. There was a difference in the beliefs between institutions with the professors at the research institution holding an incomplete view of inquiry while the professors at the private college and community college included many aspects of the inquiry continuum in their view of inquiry. There were no differences noted between disciplines.

Show moreThe current study details the creation of a new scale for measuring preservice teachers' positive affect for science, the Preservice Elementary Teacher Affect Scale for Science (PETAS-S). This new instrument is designed specifically to measure the level of positive affect towards the subject of science in preservice elementary teachers. Confirmatory factor analysis reveals the instrument loads on the single factor, positive affect. Reliability is robust, with Cronbach's alpha of .96. Positive affect has shown to predict future levels of engagement in domain specific academic subjects (Ainley (&) Ainley, 2011) and is expected to aid preservice teachers in understanding the complex relationship between their students' interest and enjoyment of science with their own. This research contributes to the important role of emotion in preservice teachers' attitudes toward the subject of science and how it may affect the way they teach it to their future students.

Show moreThis Dissertation in Practice employed a mixed-methods design to identify preferred instructional methods in a college level science course as well as the self-reported challenges to learning science in college by students with a learning disability. In addition, the relationships between preferred instructional strategies and learner characteristics such as declared major, and learning disability were examined. Qualitative and quantitative data was collected from a sample of 48 participants using an electronic survey. Additionally, eight participants participated in focus groups to collect in-depth qualitative data. All participants are current students enrolled full-time at Beacon College. Each participant completed a science college course and has a diagnosed learning disability. Analysis of the data demonstrated hands-on instruction guided by the instructor is the preferred method of learning and the use of traditional lecture and cooperative learning are self-reported as being least helpful to this student population to learn science. Findings from this study were provided to Beacon College to shape instruction in science courses as well as to shape recommendations for future research activities. Intentional design of instruction following the recommendations found in this study should assist in increasing student performance in college science courses as well as increase engagement to science as a process and field of study.

Show moreThe purpose of this study was to identify how ongoing science professional development impact students' achievement on standardized assessments. The students' end-of-year assessment and State Science Assessment data were collected from a Central Florida school district. The student data were divided into categories based on teachers' participation in on-going professional development opportunities. The teachers were categorized by the number of types of professional development opportunities they attended. The mean assessment scores of students whose all teachers did or did not participate were calculated, and t-tests were run to find the significance between the means. There was no significance in the difference between the means student scores of the participants and the non-participants in the science professional development opportunities. Two sub group data, 8th-grade free and reduced lunch students whose teacher attended one professional development, and 7th-grade students who scored a Level 3 on FSA mean scores on the science assessments scores were higher with significance in the 2015-16 school year, and were not higher the on the science assessments with significance in the 2014-15 school year.

Show moreBackground: Job satisfaction is essential to retain teachers in classrooms. Increased challenges in today's classrooms discourage many teachers from reaching veteran status. Teachers with a perception that they are making a difference appear to have more resilience in the difficult times in their classrooms. Purpose: To investigate the experiences of middle school science teachers. This study explored the influence of perceptions, beliefs, and experiences on job attrition and teacher satisfaction; and helps explain the cumulative effects that contributed to teachers' dissatisfaction. This study analyzed the intensification of the teaching profession and the increased emotional stress this causes for teachers. Setting: Five public middle schools in a large urban school district in central Florida. A total of seven teachers participated in the study. Subjects: Seven middle school science teachers were selected based on their years of experience, method of teacher training, and ability to participate in the entire study. Research Design: Phenomenological. Data Collection and Analysis: The data were collected through focus groups, interviews, journals, and classroom observations. The audio-taped portions were transcribed then analyzed with NVivo/NUD*IST, Revision 1.2 to find common themes. The initial themes were subsequently reduced for manageability. The teachers stories were separated to provide support as the themes emerged. Findings: Teachers who were more experienced by years on the job or more extensive initial training appeared to have more resilience for the difficulties in their job. Satisfaction with their job seemed to be influenced by professional identity, teacher preparation, personal experiences, curriculum policy, and cultural diversity. Conclusions: Analyzing the perceptions and beliefs of teachers who are in classrooms can provide insights to improve conditions to encourage teachers to stay. The analysis strongly suggests that teachers who feel supported and valued are more likely to remain in the classroom in spite of the challenges they encounter.

The field of science education often loses student interest due to the complexities and vocabulary found in the scientific realm. Incorporating music into the classroom has shown positive results as a way to integrate student learning and a different way of facilitating students in the learning process (Brewer, 1992; Davies, 200). Resources for implementing the integration of music and science exist throughout the Internet in a variety of mediums. This study looks at the availability of said resources and the concepts they cover, for what students they are intended for, how are they intended to be used and the level of accuracy they maintain. Those resources upholding the accuracy desired for use in the classroom were then compiled onto one webpage for use by elementary science educators. The webpage is open and free to the public and may be shared.

Show moreThe purpose of the study was to explore and describe the perceptions of several elementary science mentors and their mentees within one school district based on a five-factor mentoring model. Utilizing a qualitative methodology in the form of a case study, five mentors and three mentees were interviewed using a structured protocol. From verbatim interview data and field notes, three themes pertaining to the role of the mentor within elementary science emerged as emotional support, technical support, and educative support. Within the five-factor mentoring model, personal attributes suggested notions of support and expert status as critical elements for effective mentoring. The factors of system requirements, pedagogical knowledge, modeling, and feedback were found to be interrelated amongst themselves and with the factor of personal attributes. Effective mentors demonstrated a commitment to the role as well as a flexibility pertaining to role adjustment depending on the context of the mentoring relationship.

Show moreThis dissertation studied the beliefs and practices of principals, workshop site coordinators, and science support personnel in two Central Florida school districts and compared those beliefs and practices to the literature on effective science in-service education. It is important to understand these beliefs and practices because they directly affect the content and pedagogical knowledge of classroom teachers, yet this aspect of instructional practices has been ignored in the science education literature. This study used a grounded theory methodology using open-ended individual interviews, participants observation, and documented analysis. Constant comparisons were built through analyzing the data. The research shows that in-service providers' and administrators' beliefs are aligned with the effective science education in-service literature. The conditions and context are ripe for changes because principals and workshop site coordinators' beliefs are aligned with the literature and changes are already beginning to take place. The intervening conditions may lead to improved teacher knowledge, teaching, and learning because standardized testing is expanding to incoporate the content area of science. Also workshop site coordinators are trying to set up a variety of opportunities to attend workshops on the same topic throughout the school year. Budgets are being restructured at the school level and district level to incorporate more science content professional development. However, it is too early to show how much improvement there will be in standardized test scores or whether teachers' have a deeper understanding of science content knowledge or effective science instruction.

Show moreThe objective of this study was to evaluate and compare the effects of face-to-face and virtual laboratories in a large-enrollment introductory biology course on students' motivation to learn biology. The laboratory component of post-secondary science courses is where students have opportunities for frequent interactions with instructors and their peers (Seymour (&) Hewitt, 1997; Seymour, Melton, Wiese, (&) Pederson-Gallegos, 2005) and is often relied upon for promoting interest and motivation in science learning (Hofstein (&) Lunetta, 2003; Lunetta, Hofstein, (&) Clough, 2007). However, laboratory courses can be resource intensive (Jenkins, 2007), leading post-secondary science educators to seek alternative means of laboratory education such as virtual laboratories. Scholars have provided evidence that student achievement in virtual laboratories can be equal to, if not higher than, that of students in face-to-face laboratories (Akpan (&) Strayer, 2010; Finkelstein et al., 2005; Huppert, Lomask, (&) Lazarowitz, 2002). Yet, little research on virtual laboratories has been conducted on affective variables such as motivation to learn science.Motivation to learn biology was measured at the beginning and end of the semester using the Biology Motivation Questionnaire (&)copy; (Glynn, Brickman, Armstrong, (&) Taasoobshirazi, 2011) and compared between the face-to-face and virtual laboratory groups. Characteristics of the two laboratory environments were measured at the end of the semester by the Distance Education Learning Environment Survey (Walker (&) Fraser, 2005). Interviews with 12 participants were conducted three times throughout the semester in the phenomenological style of qualitative data collection. The quantitative survey data and qualitative interview and observation data were combined to provide a thorough image of the face-to-face and virtual laboratory environments and their impacts on students' motivation to learn biology.Statistical analyses provided quantifiable evidence that the novel virtual laboratory environment did not have a differential effect on students' motivation to learn biology, with this finding being supported by the qualitative results. Comparison of the laboratory environments showed that students in the face-to-face labs reported greater instructional support, student interaction and collaboration, relevance of the lab activities, and authentic learning experiences than the students in the virtual labs. Qualitative results indicated the teaching assistants in the face-to-face labs were an influential factor in sustaining students' motivation by providing immediate feedback and instructional support in and out of the laboratory environment. In comparison, the virtual laboratory students often had to redo their lab exercises multiple times because of unclear directions and system glitches, potential barriers to persistence of motivation. The face-to-face students also described the importance of collaborative experiences and hands-on activities while the virtual laboratory students appreciated the convenience of working at their own pace, location, and time. According to social cognitive theory (Bandura, 1986, 2001), the differences in the learning environments reported by the students should have had ramifications for their motivation to learn biology, yet this did not hold true for the students in this study. Therefore, while these laboratory environments are demonstrably different, the virtual laboratories did not negatively impact students' motivation to learn biology and could be an acceptable replacement for face-to-face laboratories in an introductory biology course.

Show moreBiochemistry has continued to be one of the most complex and important subjects in science education. The purpose of this research is to investigate active learning implementation methods in a Biochemistry I context to determine the most effective means of preparing current science undergraduates. Two Biochemistry I classes over two semesters were analyzed in this study, with class A using a variable active learning schedule and class B using a consistent active learning schedule. Four aspects were analyzed to determine active learning validity: perception of different active learning properties, standardized final exam grades, class grade, and teaching implementation. The consistent schedule of daily active learning in class B showed an increase in mean final exam score by 12.72%, significantly improved mean student grade in the class from a high C to a low B (p= 0.0038), and comparing student perception of active learning data, showed a significant decrease in student desire for passive learning (p= 0.025), increased desire for active learning (p= 0.022), and increased desire for flipped classrooms (p= 0.042) after first experiencing opposite results in the first semester of implementation which had increased desire for passive learning (p= 0.003) and teacher-centric learning (p= 0.026). A variable active learning schedule showed no significant values besides an increase in individual learning desire (p= 0.037) and a marginally significant increase in desire for passive learning (p= 0.053) both in its second semester of implementation. This research supports that a consistent, daily active learning curriculum making up approximately 40-50% of daily instruction is preferable compared to a variable lecture schedule with active learning days in between lecture days in undergraduate Biochemistry I large-class instruction given that professors perform it over multiple semesters.

Show moreThis study attempted to verify points of intersection (POIs) between mathematics and science in the eighth grade Sunshine State Standards (SSS), and to develop a valid and reliable instrument to evaluate these POIs as they were presented in the respective mathematics and science textbooks approved for use in Florida public schools. Shannon and Weaver (1998) delineated a process for content analysis that informed the design of this analysis. The process began with an analysis of the SSS to uncover POIs between mathematics and science; considered effective strategies for presenting these points of intersection in the classroom; and examined the textbooks for a mutually supportive presentation of the POIs between the two domains. The criterion for textbook evaluation was synthesized from documents used by the National Research Council (NRC, 2004) and Project 2061 (Roseman, Kulm, Shuttleworth, 2001. These criteria were examined in terms of measureable elements of textbook design, vocabulary, inquiry and problem solving in order to create integrated objectives, which were then operationalized so that each objective could be evaluated using the Textbook Evaluation Document (TED). The validity of the TED was insured by the transparency of the process. Reliability was determined in two steps, first to determine the most reliable segments of the document and finally to confirm the reliability of those segments. It was determined that the vocabulary section of the TED consistently produced reliability scores above 70% with variation of Supportive Curriculum Scores (SCS) between textbooks. This indicated that a measure of supportive vocabulary could be generated for use in future studies for example correlating supportive curriculum with student achievement.

Show moreResearch indicates that a proportion of elementary teachers are not comfortable teaching science to young children. These teachers are unaware of the best methods of approaching science and don't have the science background knowledge to support teaching through inquiry methods. This case study explores the role educative curriculum materials play in supporting pre-service early childhood education teachers' knowledge with science content and teaching practices. Specifically, I examine how educative materials impact pre-service teacher's content knowledge in science and their pedagogical content knowledge related to inquiry methods. Three pre-service early childhood teachers participated in this research. The teachers were initially interviewed about teaching science based upon three instruments: Views of Science Inquiry, Views of the Nature of Science and the Science Teachers Efficacy Beliefs Inventory. Each subject was observed teaching science in their internship site: the first lessons taught were guided or approved by their teachers and the next lessons were conducted using the support of educative curriculum materials. Finally, the initial instruments were once again administered along with an interview to obtain changes in teacher's knowledge, beliefs and understandings of science and science teaching. Results from this research indicate that educative curriculum was supportive of teachers in a variety of ways. Most importantly, this curriculum helped teachers to target more aspects of scientific inquiry during their science lessons than lessons without the use of educative curriculum. The important considerations regarding the effectiveness of the educative curriculum for these pre-service teachers were their underlying beliefs about how science should be taught, their uses of the curriculum materials and reflective practices regarding their own teaching. Results specifically related to early childhood educators include the level of inquiry implemented with young children and how children communicate their findings. Young children need support in their participation of inquiry learning. Successful implementation of guided inquiry practices occurred in this research. Also, the teachers in this research found insightful ways that directly supported young children in their communication of ideas. Implications for further research are also discussed. Educative materials could further support pre-service early childhood teachers if additional supports were used including accessible curricular rationales, support in classroom management and the specific use of guided inquiry.

A purposive sample of 14 6th-grade students engaged in think aloud interviews (Ericsson & Simon, 1993) while completing an excerpted Test of Graphing in Science (TOGS) (McKenzie & Padilla, 1986). Hand gestures were video recorded. Student performance on the TOGS was assessed using an assessment rubric created from previously cited factors affecting students' graphing ability. Factors were categorized using Bertin's (1983) three graph question levels. The assessment rubric was validated by Padilla and a veteran mathematics and science teacher. Observational notes were also collected. Data were analyzed using Roth and Bowen's semiotic process of reading graphs (2001). Key findings from this analysis included differences in the use of heuristics, self-generated questions, science knowledge, and self-motivation. Students with higher prior achievement used a greater number and variety of heuristics and more often chose appropriate heuristics. They also monitored their understanding of the question and the adequacy of their strategy and answer by asking themselves questions. Most used their science knowledge spontaneously to check their understanding of the question and the adequacy of their answers. Students with lower and moderate prior achievement favored one heuristic even when it was not useful for answering the question and rarely asked their own questions. In some cases, if students with lower prior achievement had thought about their answers in the context of their science knowledge, they would have been able to recognize their errors. One student with lower prior achievement motivated herself when she thought the questions were too difficult. In addition, students answered the TOGS in one of three ways: as if they were mathematics word problems, science data to be analyzed, or they were confused and had to guess. A second set of findings corroborated how science background knowledge affected graph interpretation: correct science knowledge supported students' reasoning, but it was not necessary to answer any question correctly; correct science knowledge could not compensate for incomplete mathematics knowledge; and incorrect science knowledge often distracted students when they tried to use it while answering a question. Finally, using Roth and Bowen's (2001) two-stage semiotic model of reading graphs, representative vignettes showed emerging patterns from the study. This study added to our understanding of the role of science content knowledge during line graph interpretation, highlighted the importance of heuristics and mathematics procedural knowledge, and documented the importance of perception attentions, motivation, and students' self-generated questions. Recommendations were made for future research in line graph interpretation in mathematics and science education and for improving instruction in this area.

Show moreThis ethnographic study of emerging inquiry-based science instruction in an urban, low socioeconomic elementary school science lab was designed to gain insight into the perspectives of the teacher and students. The study involved a Central Florida elementary school whose population was over 80 percent African-American. In this six month study, the researcher examined the classroom setting of a science lab teacher and her fourth and fifth grade students during a six month period of time. Data sources included interviews, field notes, reflections, and student work , which were used to identify the emerging themes and patterns in the study. The emergent themes were grouped into two categories: the perspective of the teacher and students in the inquiry environment and the microculture of the teacher and students in that environment. The teacher's perspectives on instructional strategies, standard based instructional guidelines, and the realities of teaching in an urban low socioeconomic setting were the major emergent themes. The students' perspectives into environment and sense-making of elementary school students were the other major emergent themes. Chapter I provides background and the significance of the study. Chapter II provides a research of the literature surrounding inquiry-based instruction in science education. Chapter III describes the methodology, specifically the ethnographic approach to this study. A metaphoric journey down the river of perspectives in science lab classroom sets the tone for Chapter IV. This chapter provides a "view from the shore," an introduction to the general background of the elementary school. Chapter V explores the teacher perspectives, and uses vignettes to analyze instructional strategies, questioning, assessment, standards state and district guideline and the realities of teaching. Chapter VI discusses the student perspectives, and uses vignettes to analyze behaviors and actions, responsibility of learners, assessment, and ways of knowing. Chapter VII pulls together conclusions, implications, and recommendations for further research.This study contributes to the total body of research of science education in two ways: 1. It provides student and teacher perspectives on science in an urban, low socioeconomic elementary school. 2. It provides research with a teacher and student perspective of inquiry-based science instruction.

Show moreThis ethnographic case study investigated one elementary school to understand how the school's culture influenced its science curriculum design and instruction. The main data was formal and informal semi-structured interviews with key teachers to understand their values, beliefs, practices, materials, and problems with science instruction. To triangulate these data, the researcher observed classroom practice, school-wide activities, and collected artifacts and documents. Data were analyzed using a theoretical framework that emphasizes that culture cannot be reduced to beliefs, values, practices, materials or problems, but rather each aspect of culture is interdependent and mutually reinforcing. The main finding suggests that the school's culture is organized to accomplish other curricular goals than effective science education. Science is rarely taught by most teachers and rarely taught well when it is. While the teachers know the rhetoric of effective science education and value it enough to not dismiss it entirely, most value it less than most other subjects and they are not proficient with science instruction and materials. This study builds upon the literature by reiterating that school culture plays a central role in elementary science education, but adds to that literature by emphasizing that culture cannot be reduced to one or a few factors and must be seen as an organic whole.

Show moreA problem within science education in the United States persists. U.S students rank lower in science than most other students from participating countries on international tests of achievement (National Center for Education Statistics, 2003). In addition, U.S. students overall enrollment rate in high school Advanced Placement (AP) physics is still low compared to other academic domains, especially for females. This problem is the background for the purpose of this study. This investigation examined cognitive and motivational variables thought to play a part in the under-representation of females in AP physics. Cognitive variables consisted of mathematics, reading, and science knowledge, as measured by scores on the 10th and 11th grade Florida Comprehensive Assessment Tests (FCAT). The motivational factors of attitude, stereotypical views toward science, self-efficacy, and epistemological beliefs were measured by a questionnaire developed with question taken from previously proven reliable and valid instruments. A general survey regarding participation in extracurricular activities was also included. The sample included 12th grade students from two high schools located in Seminole County, Florida. Of the 106 participants, 20 girls and 27 boys were enrolled in AP physics, and 39 girls and 20 boys were enrolled in other elective science courses. Differences between males and females enrolled in AP physics were examined, as well as differences between females enrolled in AP physics and females that chose not to participate in AP physics, in order to determine predictors that apply exclusively to female enrollment in high school AP physics and predictors of an anticipated science related college major. Data were first analyzed by Exploratory Factor Analysis, followed by Analysis of Variance (ANOVA), independent t-tests, univariate analysis, and logistic regression analysis. One overall theme that emerged from this research was findings that refute the ideas that females have lower achievement scores, lower attitude, lower self-efficacy, and more stereotypical views regarding science than males. Secondly, the only significant differences found between males and females enrolled in AP physics were for stereotypical views toward science and one factor from the epistemological views questions, both of which favored females. Although the non AP boys significantly outscored non AP girls on science FCAT scores, the only other significant differences found between these groups of students were related to attitude, with the girls scoring higher than the boys on both counts. There were significant differences found for numerous variables between AP and non AP females, however, most of the same differences were found between the two ability groups of male students as well. This leads to the conclusion that these factors certainly play an important role in AP physics enrollment for both genders. But the few significant differences found exclusively between the two female ability groups; reading ability, stereotypical views toward science, and the epistemological beliefs regarding branches of physics being related by common principles and aspects of physics need to be inferred instead of directly measured, may play a more important role in increasing enrollment numbers of females.

Title: THE EFFECTS OF INQUIRY AND SINGLE-GENDER GROUPING ON SECOND GRADE GIRLS' ATTITUDES AND PARTICIPATION IN SCIENCE.
Creator: Estrada, Elsy, Jeanpierre, Bobby, University of Central Florida
Abstract / Description: Disparities between males and females in attitudes toward science have been the focus of extensive investigations. Studies have found that females feel intimidated by their male peers in science and mathematics classes, making girls less likely to participate. Their confidence in these areas decreases and they become less likely to follow related career paths. Researchers and educators are at task to find methods to provide equal learning opportunities for all students. The purpose of this...
Show moreDisparities between males and females in attitudes toward science have been the focus of extensive investigations. Studies have found that females feel intimidated by their male peers in science and mathematics classes, making girls less likely to participate. Their confidence in these areas decreases and they become less likely to follow related career paths. Researchers and educators are at task to find methods to provide equal learning opportunities for all students. The purpose of this action research was to investigate the effects of single-gender grouping and inquiry-based teaching on girls' participation and attitude in science class. This study took place in a second grade classroom at a suburban school in the fall of 2005. Surveys and interviews were used to investigate students' attitudes before and after working with inquiry learning single-gender groups. Using observations, female students' participation was recorded according to the kind of participation they exhibited – passive/assisting, active/leading, or active/manipulating. Students maintained journals to record their understanding of science content and rated the lessons. In addition to improving female students' attitudes towards science, inquiry learning fostered an increase in active student participation. Six out of the eight female students perceived that girls participated more in single-gender groups during the study than they did before the study in their regular mixed-gender groups. However, they did not report a change in their own participation in relation to their peers after working in single-gender groups. Further research with control groups was suggested with a larger and more socio-economically diverse population.
