Step 1: Prepare for the process Step 2: Establish Team Step 3: Describe the Problem Step 4: Develop short term containment action Step 5: Define and verify root cause and escape point Step 6: Choose and verify permanent corrective actions Step 7: Implement and validate permanent corrective actions Step 8: Prevent recurrence Step 9: Recognize team and individual contributions Step 10: Benchmarking The ten step problem solving process is an enhancement to 6-sigma process that is currently used by many manufacturers. Consumer Driven 6-Sigma is a tool that significantly improves customer satisfaction and shareholder value by reducing variability in every aspect of the business. It builds on existing processes, provides additional tools, and offers a disciplined approach to focus on meeting customer expectations. 6-Sigma helps on finding out where the variability is in a process, and then provides the tools to reduce variability and make the process better.

Show moreThis study summarizes research conducted in a second grade classroom at a rural elementary school in the fall of 2004. This study investigated the practice of using writing activities in mathematics to improve student attitudes and performance in problem solving. The classroom teacher supplemented traditional mathematics instruction with daily problem solving activities and affective journal writing. Students were asked to complete daily problem solving prompts and write about their problem-solving solutions. Attitude data was collected using a pre and post attitude survey as well as affective journal writing assignments. Performance data was collected using a performance based problem-solving rubric. Results of this study showed change in students' attitudes towards problem solving in the areas of willingness to participate and perseverance in completing problem solving tasks. Student performance gains were recorded and analyzed throughout the six-week study period. Thirteen out of the 17 students who participated in this study showed performance growth in problem solving.

Show moreThe purpose of this research was to examine special event management as a temporary business model and how it is impacted by problem solving capabilities in its utilization of temporary systems. The phenomenon of special events management and how event leaders must continuously make decisions based upon knowledge, skill, and intuition are the constructs of why events operations are as unique as the events themselves. A paradigm of temporary operational organizations that depend on communication, information, and implementation of operational strategies within unusual and unique environments and on a continuous basis must rely on appropriate instructional systems. The instructional methods that are selected should support event leadership's problem solving methods in accomplishing the goals and mission of the special event.

Show moreClassic studies have examined the factors that influence the way in which people can solve difficult (")insight(") problems, which require creative solutions. Recent research has shown that guiding one's eye movements in a pattern spatially congruent with the solution improves the likelihood of formulating a spatial solution. The authors in this line of research argued that guiding eye movements in a pattern spatially equivalent to the solution of the problem yields an embodied cognitive benefit that aids problem solving. Specifically, guiding eye movements leads to the generation of a mental representation containing perceptual information that helps a problem solver mentally simulate the problem features, increasing likelihood to generate a solution to the problem. However, evidence from a small but critically relevant area of research supports that this embodied effect may be more simply a creativity-priming effect. The proposed research aimed to disentangle these ideas while addressing other research questions of interest: do embodied problem solving benefits transfer to later problem solving? Do individual differences in spatial ability influence how people solve these problems? The present study combined previously established methodologies in problem solving and analogical problem solving to investigate these research questions. Results of the present work tentatively support the embodied priming effect, mediated by a creativity-priming effect that influences problem solving performance. Both effects emerged after manipulating problem solvers' eye movements. There is also modest support for a link between spatial ability and analogical problem solving, but not initial problem solving. These results are interpreted through the lens of embodied cognitive theory, providing tentative support that guiding eye movements can influence reasoning through an enhancement of creativity.

The study was conducted to determine the effect of integrating writing with mathematics on students' achievement in, and attitudes towards problem solving, and the relationship between students' attitudes and their achievement in problem solving. The study was conducted over a six-week period. Students participated in daily problem solving activities. Data were collected using a problem solving themed writing rubric for evaluating student journal responses, anecdotal records, and using a pre- and posttest problem solving attitude inventory. In this study, students demonstrated overall increased mathematical knowledge, strategic knowledge, and abilities to explain their procedures. In addition, all three data-collection instruments demonstrated students' positive attitudes toward problem solving. Moreover, evaluation of the data sources illustrated a relationship between students' performance and attitudes. The study suggested that writing about mathematics is beneficial to students' achievement and attitudes toward problem solving.

Show moreThe purpose of this dissertation is to explore employees' behavioral reactions to the perceived aggression of others. Perceived aggression is defined as behavior that is perceived to be intentionally harmful by the intended target. A typology is developed that identifies two primary dimensions of behavioral reaction: (1) the form of the behavior (aggression/non-aggression) and (2) the direction of the behavior (toward the source of the harm/not toward the source of the harm). Based on these dimensions, the typology produces four categories of behavioral reactions: retaliatory aggression, displaced aggression, constructive problem-solving, and withdrawal. A model is then presented, which identifies various factors that influence employees' reactions. The relationships are examined in two studies. The first study is a cross-sectional survey design, which investigates the reactions to perceived supervisor aggression and the moderating effects of various situational factors (fear of retaliation, aggressive modeling and absolute hierarchical status) and individual factors (trait anger and the need for social approval). The second study is a 2x2 experimental design that investigates the reactions to perceived aggression and the moderating effects of fear of retaliation and personality variables (trait anger, locus of control and the need for social approval). Participants of the experiment, 77 undergraduate students, were randomly assigned into conditions of perceived aggression (high/low) and fear of retaliation (high/low). Perceived aggression was manipulated through exam feedback and fear of retaliation was manipulated through anonymity of instructor evaluations. The results of both studies provide support for some of the predictions, as well as some contradictory findings. Conclusions are drawn from the theory, typology and findings of the studies, highlighting implications for future aggression and organizational behavior research.

Show moreThis dissertation evaluates the relationship between five team knowledge building processes (i.e., information exchange, knowledge sharing, option generation, evaluation of alternatives, and regulation), the external representations constructed by a team during a performance episode, and performance outcomes in a problem solving task. In a broad range of domains such as the military, and healthcare, team-based work structures used to solve complex problems; however, the bulk of research on teamwork to date has dealt with behavioral coordination in routine tasks. This leaves a gap in the theory available for developing interventions to support collaborative problem solving, or knowledge-based performance, in teams. Sixty nine three person teams participated in a strategic planning simulation using a collaborative map. Content analysis was applied to team communications and the external representations team members created using the collaborative tool. Regression and multi-way frequency analyses were used to test hypotheses about the relationship between the amount and sequence of team process behaviors respectively and team performance outcomes. Additionally, the moderating effects of external representation quality were evaluated. All five team knowledge building processes were significantly related to outcomes, but only one (i.e., knowledge sharing) in the simple, positive, and linear way hypothesized. Information exchange was negatively related to outcomes after controlling for the amount of acknowledgements team members made. Option generation and evaluation interacted to predict outcomes such that higher levels of evaluation were more beneficial to teams with higher levels of option generation. Regulation processes exhibited a negative curvilinear relationship with outcomes such that high and low performing teams engaged in less regulation than did moderately performing teams. External representation quality moderated a composite team knowledge building process variable such that better external representations were more beneficial for teams with poorer quality processes than for teams with high quality process. Additionally, there were significant differences in the sequence of team knowledge building processes between high and low performing teams as well as between groups based on high and low levels of external representation quality. The team knowledge building process framework is useful for understanding complex collaborative problem solving. However, these processes predict performance outcomes in complex and inter-related ways. Further implications for theories of team performance and applications for training, designing performance support tools, and team performance measurement are discussed.

Show moreThe purpose of this action research study was to observe the influence of teaching mathematical problem solving strategies on students' attitudes in middle school. The goal was to teach five problem solving strategies: Drawing Pictures, Making a Chart or Table, Looking for a Pattern, Working Backwards, and Guess and Check, and have students reflect upon the process. I believed that my students would use these problem solving strategies as supportive tools for solving mathematical word problems. A relationship from the Mathematics Attitudes survey scores on students' attitudes towards problem solving in mathematics was found. Students took the Mathematics Attitudes survey before and after the study was conducted. In-class observations of the students applying problem solving strategies and students' response journals were made. Students had small group interviews after the research study was conducted. Therefore, I concluded that with the relationship between the Mathematics Attitudes survey scores and journal responses that teaching the problem solving strategies to middle school students was an influential tool for improving students' mathematics attitude.

The results indicate that students do not have a full understanding of the role of a free-body diagram or its relationship to the system of equations that are generated as a result of the application of NewtonÂÂÂÂ's Second Law to the free-body diagram.

Show moreIn this multiple-case study, I developed cases describing three students' (Mary, Ryan and David) solution methods for algebra word problems and investigated the effect of technology on their solution methods by making inferences about their preferences for visual or nonvisual solutions. Furthermore, I examined the students' solution methods when presented with virtual physical representations of the situations described in the problems and attempted to explain the effect of those representations on students' thinking preferences. In this study, the use of technology referred to the use of the dynamic software program Geogebra. Suwarsono's (1982) Mathematical Processing Instrument (MPI) was administered to determine their preferences for visual and nonvisual thinking. During the interviews, students were presented with paper-and-pencil-based tasks (PBTs), Geogebra-based tasks (GBTs) and Geogebra-based tasks with virtual physical representations (GBT-VPRs). Each category included 10 algebra word problems, with similar problems across categories. (i.e., PBT 9, GBT 9 and GBT-VPR 9 were similar). By investigating students' methods of solution and their use of representations in solving those tasks, I compared and contrasted their preferences for visual and nonvisual methods when solving problems with and without technology. The comparison between their solutions of PBTs and GBTs revealed how dynamic software influenced their method of solution. Regardless of students' preferences for visual and nonvisual solutions, with the use of dynamic software students employed more visual methods when presented with GBTs. When visual methods were as accessible and easy to use as nonvisual methods, students preferred to use them, thus demonstrating that they possessed a more complete knowledge of problem-solving with dynamic software than their work on the PBTs. Nowadays, we can construct virtual physical representations of the problems in technology environments that will help students explore the relationships and look for patterns that can be used to solve the problem. Unlike GBTs, GBT-VPRs did not influence students' preferences for visual or nonvisual methods. Students continued to rely on methods that they preferred since their preferences for visual or nonvisual solutions regarding GBT-PRs were similar to their solution preferences for the problems on MPI that was administered to them to determine their preferences for visual or nonvisual methods. Mary, whose MPI score suggested that she preferred to solve mathematics problems using nonvisual methods, solved GBT-VPRs with nonvisual methods. Ryan, whose MPI score suggested that he preferred to solve mathematics problems using visual methods, solved GBT-VPRs with visual methods. David, whose MPI score suggested that he preferred to solve mathematics problems using both visual and nonvisual methods, solved GBT-VPRs with both visual and nonvisual methods.

Show moreThere are two purposes to this study. The first was for me, as a teacher, to try something new in my instruction and grow from it. The second purpose of this study focused on the students. I wanted to see what level of performance in problem solving my students are at currently, and how the use of journaling and discourse affected the students' problem solving abilities. A problem-solving unit was taught heuristically in order to introduce students to the various strategies that could be used in problem solving. Math journals were also used for problem solving and reflection. Classroom discourse in discussion of problem solving situations was used as a means of identifying strategies used to solve the problem. Explanations and justifications were then used in writing and discourse to support students' solution and methods. An analytic problem-solving rubric was used to score the problems solved by the students. These scores, along with explanations and justifications, and discourse were used as data and analyzed for common themes. The results of this study demonstrate overall improvement in student performance in problem solving. Heuristic instruction the students received on strategies in problem solving helped to improve their ability to not only select an appropriate strategy, but also implement it. This unit, along with the problem solving prompts solved in the journals, helped to improve the students' performance in explanations. It was discourse combined with all the previous instruction that finally improved student performance in justification.

Show moreThis study investigated the applicability of a general model of physics students' problem-solving experiences that suggests there are four dynamic factors affecting the problem-solving process: categorization, goal interpretation, resource relevance, and complexity. Furthermore, it suggests an overarching control factor called stabilization, which describes the inter-relatedness of the other factors over the problem-solving process. Think-aloud protocols of problem-solving experiences were used to investigate the model. Results of the study showed that conceptual resources had a significant impact on the success of problem-solving attempts. Participants who exhibited a lack of understanding of physics concepts were less likely to check their work, use diagrams effectively, set subgoals, or to use geometric or trigonometric resources, and were more likely to use a formula-driven search for a solution than those who exhibited evidence of conceptual understanding. However, conceptual understanding did guarantee problem-solving success. Mathematical and procedural knowledge was also seen as important. While many of the specific observations were consistent with the existing literature, the model provides an alternative framework with which to understand and synthesize those observations. The model was shown to be partially successful in describing participants' problem-solving experiences. Categorization, resource relevance and goal interpretation were supported to varying degrees; however, there was less evidence to support the construct of complexity. Determination of evidence for stabilization was guided by a working definition based on the participants' search for a stable understanding of the problem. Implications of these results for research and practice were noted.

Show moreThis study sought to understand effective and ineffective instructional practices in clinical settings and to identify problem-solving strategies used by students and instructors. Three research questions were addressed: where in the undergraduate athletic training education program do students learn, or fail to learn, particular skills; "what instructional methods are of most worth" in teaching these skills, as perceived by the students; and what are the problem-solving strategies used by novice, experienced non-expert, and expert athletic trainers when confronted with novel situations. The subjects were nine students ("novices") and ten Approved Clinical Instructors (ACI's) from three programs in the Southeast United States. Five ACI's were categorized as "experienced non-experts" and five as "experts". All subjects were videotaped while performing various tasks. Each subject was required to think-aloud while they performed typical tasks expected of an entry-level certified athletic trainer, as designated by the NATA Education Council. Subjects then performed a stimulated-recall session, with analysis adapted from Ericsson and Simon (1993). The main findings of this study supported the well-respected teaching notion of "first teach them, then show them, then have them do it". Most concepts were first taught via lecture in the classroom; however, participants believed the "method of most worth" to be hands-on strategies displayed in clinical settings and labs. This study confirmed and disconfirmed aspects of prior research on problem solving. Experts: offered the most verbal comments, used their self-talk to stay on task, displayed intimate rapport with the models, and used various problem-solving strategies based upon the task at hand. Experienced non-experts: tended to drift in their verbal comments, felt the need to justify their answers, spoke mostly with verbal commands, and used several problem solving strategies. Novices: provided the fewest verbal comments, apologized throughout their sessions, often found the problem statement to be the problem itself, and used basic problem solving strategies. Demographics revealed that close relationships, balanced with manageable ACI's and clinical sites, created the most successful programs. Based on the findings of this study, future research must focus on how to best design the curriculum to take advantage of these "methods of most worth".

Show moreThis dissertation contributes an enhanced understanding of team cognition, in general, and collaborative problem solving (CPS), specifically, through an integration of methods that measure team interaction dynamics and knowledge building as it occurs during a complex CPS task. The need for better understanding CPS has risen in prominence as many organizations have increasingly worked to address complex problems requiring the combination of diverse sets of individual expertise to achieve solutions for novel problems. Towards this end, the present research drew from theoretical and empirical work on Macrocognition in Teams that describes the knowledge coordination arising from team communications during CPS. It built from this by incorporating the study of team interaction during complex collaborative cognition. Interaction between team members in such contexts has proven to be inherently dynamic and exhibiting nonlinear patterns not accounted for by extant research methods. To redress this gap, the present research drew from work in cognitive science designed to study social and team interaction as a nonlinear dynamical system. CPS was examined by studying knowledge building and interaction processes of 43 dyads working on NASA's Moonbase Alpha simulation, a CPS task. Both non-verbal and verbal interaction dynamics were examined. Specifically, frame-differencing, an automated video analysis technique, was used to capture the bodily movements of participants and content coding was applied to the teams' communications to characterize their CPS processes. A combination of linear (i.e., multiple regression, t-test, and time-lagged cross-correlation analysis), as well as nonlinear analytic techniques (i.e., recurrence quantification analysis; RQA) were applied. In terms of the predicted interaction dynamics, it was hypothesized that teams would exhibit synchronization in their bodily movements and complementarity in their communications and further, that teams more strongly exhibiting these forms of coordination will produce better problem solving outcomes. Results showed that teams did exhibit a pattern of bodily movements that could be characterized as synchronized, but higher synchronization was not systematically related to performance. Further, results showed that teams did exhibit communicative interaction that was complementary, but this was not predictive of better problem solving performance. Several exploratory research questions were proposed as a way of refining the application of these techniques to the investigation of CPS. Results showed that semantic code-based communications time-series and %REC and ENTROPY recurrence-based measures were most sensitive to differences in performance. Overall, this dissertation adds to the scientific body of knowledge by advancing theory and empirical knowledge on the forms of verbal and non-verbal team interaction during CPS, but future work remains to be conducted to identify the relationship between interaction dynamics and CPS performance.

Show moreThe purpose of this study was to investigate the effect of teachers attending Cognitively Guided Instruction (CGI) professional development on students' problem solving strategies and the effect of students' use of strategies on their mathematics achievement as measured by a standardized test. First, the study analyzed the differences in students' use of strategies between treatment and control groups. The treatment was CGI professional development, and the teachers in the treatment group attended CGI workshops whereas the teachers in the control group did not. Next, the study analyzed the differences in the mathematics achievement of students between different strategy groups. A student posttest, which was ITBS (Math Problems and Math Computation), was used to compare students' mathematics achievement. A student pretest was used as a covariate. The results of this study showed that there were statistically significant differences in the students' use of strategies between the treatment and control groups at the second grade level. A greater percentage of treatment students used derived facts / recall strategies (the most advanced strategy for single-digit addition and subtraction) than control students did. The results related to the effect of students' use of strategies on their mathematics achievement showed that the students who used derived facst/recall strategies for single-digit problems had significantly higher mathematics achievement than students who used counting or concrete modeling strategies. Furthermore, the students who used invented algorithms for multi-digit problems had significantly higher mathematics achievement than the students who used standard algorithms.

Show moreThe focus of this research was to expand on existing literature by providing information on elementary school pre-service teachers' ability to contextualize fraction expressions and decontextualize fraction word problems. The elementary school pre-service teachers who participated in this study were enrolled in a mathematics for elementary school teachers content course in a college of education at a large university during the Spring 2016 semester. In this mixed-method study, the participants were given the Contextualization and Decontextualization of Fractions Instrument (CDFI) which assessed elementary school pre-service teachers' ability to solve fraction word problems and identify decontextualized fraction word problems into expressions and contextualized fraction expressions into word problems. The elementary school pre-service teachers were given the CDFI before and after they completed a unit on fractions. Of the 52 participants who completed both the pre- and post- CDFI, 11 were selected to participant in think aloud interviews in which they decontextualized fraction expressions from word problems and solved and contextualized fraction word problems from expressions. Quantitative results showed an overall statistically significant difference in the elementary school pre-service teachers' pre- and post- test scores. With the exception of two questions, all questions on the CDFI showed a statistically significant difference between the pre- and the post- test scores. No statistical significance was found in the responses to the question that required the elementary school pre-service teachers to identify the expression that matched the given fraction subtraction word problem. A large number of participants correctly identified the correct subtraction expression on the pre-test, and only slightly more of them were able to identify the correct subtraction expression on the post-test. No statistical significance was found in the responses to the question that required the elementary school pre-service teachers to explain their selection of a contextualized fraction multiplication expression. Though there was an increase in the elementary school pre-service teachers' ability to explain their selection of the contextualized fraction multiplication expression, it was not statistically significant. The qualitative analysis of the think aloud interview data showed that some of the elementary school pre-service teachers struggled with contextualizing fraction expressions. Most of the elementary school pre-service teachers did not struggle with solving the fraction word problems, but did struggle with decontextualizing fraction multiplication word problems.

Show moreThe purpose of this study was primarily to explore the conceptualization of critical thinking development in radiologic science students by radiography program directors. Seven research questions framed three overriding themes including 1) perceived definition of and skills associated with critical thinking; 2) effectiveness and utilization of teaching strategies for the development of critical thinking; and 3) appropriateness and utilization of specific assessment measures for documenting critical thinking development. The population for this study included program directors for all JRCERT accredited radiography programs in the United States. Questionnaires were distributed via Survey Monkey©, a commercial on-line survey tool to 620 programs. A forty-seven percent (n = 295) response rate was achieved and included good representation from each of the three recognized program levels (AS, BS and certificate). Statistical analyses performed on the collected data included descriptive analyses (median, mean and standard deviation) to ascertain overall perceptions of the definition of critical thinking; levels of agreement regarding the effectiveness of listed teaching strategies and assessment measures; and the degree of utilization of the same teaching strategies and assessment measures. Chi squared analyses were conducted to identify differences within each of these themes between various program levels and/or between program directors with various levels of educational preparation as defined by the highest degree earned. Results showed that program directors had a broad and somewhat ambiguous perception of the definition of critical thinking, which included many related cognitive processes that were not always classified as attributes of critical thinking according to the literature, but were consistent with definitions and attributes identified as critical thinking by other allied health professions. These common attributes included creative thinking, decision making, problem solving and clinical reasoning as well as other high-order thinking activities such as reflection, judging and reasoning deductively and inductively. Statistically significant differences were identified for some items based on program level and for one item based on program director highest degree. There was general agreement regarding the appropriateness of specific teaching strategies also supported by the literature with the exception of on-line discussions and portfolios. The most highly used teaching strategies reported were not completely congruent with the literature and included traditional lectures with in-class discussions and high-order multiple choice test items. Significant differences between program levels were identified for only two items. The most highly used assessment measures included clinical competency results, employer surveys, image critique performance, specific course assignments, student surveys and ARRT exam results. Only one variable showed significant differences between programs at various academic levels.

Show moreABSTRACT The purpose of this action research study was to investigate the affects of teaching through a situative perspective with story problems on students' understanding of fraction concepts and operations in my fifth-grade mathematics classroom. Students participated in twelve weeks of instruction. Data was collected in the form of pre and post tests, audiotaped and videotaped recordings of instructional sessions, and student work samples. Data analysis revealed that my students constructed their own knowledge about various fraction concepts and operations because students engaged in discussions, after solving story problems, that developed, extended and restructured their knowledge. One example of this occurred after students had solved an equal-sharing problem. Two students came up with different answers and another student explained why both answers were equivalent. Student work samples and post test results indicated that the one student's explanation was understood, adopted and extended by all the students in my class. The data also revealed that students' pictures typically represented the context and action of the story problems. For example, subtraction problems dealing with length were usually represented by number lines or horizontal rectangles with crossed-out markings to show the subtraction operation. Throughout this research study, I discovered that my students were capable of learning from each other and solving problems for which they have no preconceived algorithm. I also learned that analyzing students' work and listening to their discussions in ways that focused on their thinking, not their answers, provided me with information about what my students were grasping and not grasping.
