To answer this question, two groups of 20 participants and one group of 10 participants were tested using the Web-based Anatomy & Physiology course modules developed by Medsn, Inc. The control group received the static speed of 128 words per minute while the experimental group received the initial speed of 128 words per minute with the option to change the speed of the audio-based text. An additional experimental group received the initial speed of 148 words per minute also having the option to vary the speed of the audio-based text. A three way single variable Analysis of Variance (ANOVA) was utilized to examine speed of voice presentation differences. The results were significant, F (2, 47) = 4.67, p=0.014, ç2 = 0.166. The mean for the control group was (M = 7.2, SD = 1.69) with the experimental groups at, (M = 8.4, SD = 1.31) and with extra groups at (M = 8.6, SD = 1.26).

Show morePre-Trip Inspection of the truck and trailer is one of the components of the current Commercial Driver's License (CDL) test. This part of the CDL test checks the ability of the student to identify the important parts of the commercial vehicle and their potential defects. The Virtual Check Ride System (VCRS), a computer-based application, is an assessment and feedback tool that mirrors the inspection component of the actual CDL. The VCRS has provided an after action review (AAR) via a feedback session that helps in identifying and correcting drivers' skill in inspecting parts and for overall safety. The purpose of this research is to determine the effectiveness of the VCRS in truck driving training programs. An experimental study was conducted with truck driving students at Mid Florida Tech, located in Orlando, Florida. The students were divided into control and experimental groups. Students in the both groups received regular training provided by Mid Florida Tech. The experimental group received additional training by making use of the VCRS. A total of three paper-based tests were given to all subjects during first three weeks; one test at the end of a week. Both groups were given the same paper-based tests. A two-way analysis of variance was conducted to evaluate the effect of the VCRS in the experimental group. This analysis found a significant difference between control and experimental groups. This effect showed that the students in the experimental group increased their performance by using VCRS. Moreover, there was a main effect in the scores of each week. However, there was not an interaction between the two factors. Follow up Post Hoc tests were conducted to evaluate the pair-wise differences among the means of the test week factors using a Tukey HSD test. These Post Hoc comparisons indicated that the mean score for the third week's test scores were significantly better than the first week's test score in the experimental group. It was concluded that the VCRS facilitated learning for the experimental group and that learning also occurred for both groups as a result of repeated testing.

Show moreToday's best intelligent, adaptive, multimedia trainers have shown excellent performance; however, their results still fall far-short of what good human tutors can achieve. The overarching thesis of this paper is that future intelligent, adaptive systems will be improved by taking into account relevant, consistent, and meaningful individual differences. Specifically, responding to individual differences among trainees will (a) form more accurate individual baselines within a training system, and (b) better inform system responses (so that they interpret and respond to observable data more appropriately). One variable to consider is trait arousability, which describes individual differences in sensitivity to stimuli. Individuals' arousability interacts with the arousal inherent to a task/environment to create a person's arousal state. An individual's arousal state affects his/her attentional capacity, working memory function, and depth of processing. In this paper, two studies are presented. The purpose of the first study was to evaluate existing subjective measures of trait arousability and then develop a new measure by factor analyzing existing apparatus. From this well-populated (N = 622) study, a new reliable (α = .91) 35-item scale was developed. This scale includes two factors, negative emotionality and orienting sensitivity, which have been previously theorized but not yet so reliably measured. The purposes of the second study were to (a) validate the measure developed in the first investigation and (b) demonstrate the applied value of the arousability construct in the context of training. Results from the second study (N=45) demonstrated significant main effects, but the interaction effects were inconclusive. They neither clearly confirm nor invalidate the hypotheses, but they do raise further questions.

Show moreComputer-based training has become more prolific as the military and private businessenterprises search for more efficient ways to deliver training. However, some methods ofcomputer-based training are not more effective than traditional classroom methods. Onetechnique that may be able to approximate the most effective form of training, one-on-onetutoring, is Adaptive Training (AT). AT techniques use instruction that is tailored to the learnerin some way, and can adjust different training parameters such as difficulty, feedback, pace, anddelivery mode.There are many ways to adapt training to the learner, and in this study I exploredadapting the feedback provided to trainees based on spatial ability in line with Cognitive LoadTheory (CLT). In line with the CLT expertise reversal effect literature I hypothesized that for aspatial task, higher ability trainees would perform better when they were given less feedback.Alternately, I hypothesized that lower ability trainees would perform better during training whenthey were given more support via feedback. This study also compared two different adaptationapproaches. The first approach, called the ATI approach, adapts feedback based on a premeasuredability. In this case, it was spatial ability. The second approach, called the Hybridapproach adapts initially based on ability, but then based on performance later in training. Ihypothesized that participants who received Hybrid adaptive training would perform better.The study employed a 2(spatial ability; high, low) X 2(feedback; matched, mismatched)X 2 (approach; ATI, Hybrid) between-subjects design in which participants were randomlyassigned to one of the eight conditions. Ninety-two participants completed a submarine-basedperiscope operator task that was visual and spatial in nature. ivThe results of the study did not support the use of CLT-derived adaptation based onspatial ability; contrary to what was hypothesized, higher ability participants who received morefeedback performed better than those who received less. Similarly, lower ability participantswho received less feedback performed better than those who received more. While notsignificant, results suggested there may be some benefit to using the Hybrid approach, but moreresearch is needed to determine the relative effectiveness of this approach.

Show moreThis study explored the effectiveness of embedding a guided, learner-generated instructional strategy (query method), designed to support learners' cognitive and metacognitive processes, within the context of a computer-based complex task training environment (i.e., principles of flight in the aviation domain). The queries were presented as "stop and think" exercises in an open-ended question format that asked learners to generate either simple (low-level elaboration) or complex (high-level elaboration) sentences from a list of key training concepts. Results consistently highlighted the benefit of presenting participants with low-level elaboration queries, as compared to the no-query or high-level elaboration queries. In terms of post-training cognitive outcomes, participants presented with the low-level elaboration queries exhibited significantly more accurate knowledge organization (indicated by similarity to an expert model), better acquisition of perceptual knowledge, and superior performance on integrative knowledge assessment involving the integration and application of task-relevant concepts. Consistent with previous studies, no significant differences in performance were found on basic factual knowledge assessment. Presentation of the low-level elaboration queries also significantly improved the training program's instructional efficiency, that is, greater performance was achieved with less perceived cognitive effort. In terms of post-training metacognitive outcomes, participants presented with the low-level elaboration queries exhibited significantly greater metacomprehension accuracy and more effective metacognitive self-regulation during training. Contrary to predictions, incorporating the high-level elaboration queries into the training consistently failed, with only a few exceptions, to produce significantly better post-training outcomes than the no-query or the low-level elaboration query training conditions. The results of this study are discussed in terms of the theoretical implications for garnering a better understanding of the cognitive and metacognitive factors underlying the learning process. Practical implications for training design are presented within the context of cognitive load theory. Specifically, the increased cognitive processing of the training material associated with the high-level elaboration queries may have imposed too great a cognitive load on participants during training, minimizing the cognitive resources available for achieving a deeper, integrative understanding of the training concepts and hindering successful performance on the cognitive measures. The discussion also highlights the need for a multi-faceted approach to training evaluation.

Show moreMultimedia theory has generated a number of principles and guidelines to support computer-based training (CBT) design. However, the cognitive processes responsible for learning, from which these principles and guidelines stem from, are only indirectly derived by focusing on cognitive learning outcome differences. Unfortunately, the effects that cognitive processes have on learning are based on the assumption that cognitive learning outcomes are indicative of certain cognitive processes. Such circular reasoning is what prompted this dissertation. Specifically, this dissertation looked at the notion of referential connections, which is a prevalent cognitive process that is thought to support knowledge acquisition in a multimedia CBT environment. Referential connections, and the related cognitive mechanisms supporting them, are responsible for creating associations between verbal and visual information; as a result, their impact on multimedia learning is theorized to be far reaching. Therefore, one of the main goals of this dissertation was to address the issue of indirectly assessing cognitive processes by directly measuring referential connections to (a) verify the presence of referential connections, and (b) to measure the extent to which referential connections affect cognitive learning outcomes. To achieve this goal, a complete review of the prevalent multimedia theories was brought fourth. The most important factors thought to be influencing referential connections were extracted and cataloged into variables that were manipulated, fixed, covaried, or randomized to empirically examine the link between referential connections and learning. Specifically, this dissertation manipulated referential connections by varying the temporal presentation of modalities and the color coding of instructional material. Manipulating the temporal presentation of modalities was achieved by either presenting modalities simultaneously or sequentially. Color coding manipulations capitalized on pre-attentive highlighting and pairing of elements (i.e., pairing text with corresponding visuals). As such, the computer-based training varied color coding on three levels: absence of color coding, color coding without pairing text and corresponding visual aids, and color coding that also paired text and corresponding visual aids. The modalities employed in the experiment were written text and static visual aids, and the computer-based training taught the principles of flight to naïve participants. Furthermore, verbal and spatial aptitudes were used as covariates, as they consistently showed to affect learning. Overall, the manipulations were hypothesized to differentially affect referential connections and cognitive learning outcomes, thereby altering cognitive learning outcomes. Specifically, training with simultaneously presented modalities was hypothesized to be superior, in terms of referential connections and learning performance, to a successive presentation, and color coding modalities with pairing of verbal and visual correspondents was hypothesized to be superior to other forms of color coding. Finally, it was also hypothesized that referential connections would positively correlate with cognitive learning outcomes and, indeed, mediate the effects of temporal contiguity and color coding on learning. A total of 96 were randomly assigned to one of the six experimental groups, and were trained on the principles of flight. The key construct of referential connections was successfully measured with three methods. Cognitive learning outcomes were captured by a traditional declarative test and by two integrative (i.e., knowledge application) tests. Results showed that the two multimedia manipulation impacted cognitive learning outcomes and did so through corresponding changes of related referential connections (i.e., through mediation). Specifically, as predicted, referential connections mediated the impact of both temporal contiguity and color coding on lower- and higher-level cognitive learning outcomes. Theoretical and practical implications of the results are discussed in relation to computer-based training design principles and guidelines. Specifically, theoretical implications focus on the contribution that referential connections have on multimedia learning theory, and practical implications are brought forth in terms of instructional design issues. Future research considerations are described as they relate to further exploring the role of referential connections within multimedia CBT paradigms.
