Item A comparison of the effects of mobile device display size and orientation, and text segmentation on learning, cognitive load, and user perception in a higher education chemistry course(2015-05) Karam, Angela Marie; Resta, Paul E.; Liu, Min; Hughes, Joan E.; Riegle-Crumb, Catherine; Matthew, EastinThis study aimed to understand the relationship between mobile device screen display size (laptops and smartphones) and text segmentation (continuous text, medium text segments, and small text segments) on learning outcomes, cognitive load, and user perception. This quantitative study occurred during the spring semester of 2015. Seven hundred and seventy-one chemistry students from a higher education university completed one of nine treatments in this 3x3 research design. Data collection took place over four class periods. The study revealed that learning outcomes were not affected by the mobile screen display size or orientation, nor was working memory. However, user perception was affected by the screen display size of the device, and results indicated that participants in the sample felt laptop screens were more acceptable for accessing the digital chemistry text than smartphone screens by a small margin. The study also found that neither learning outcomes, nor working memory was affected by the text segmentation viewed. Though user perception was generally not affected by text segmentation, the study found that for perceived ease of use, participants felt medium text segments were easier to learn from than either continuous or small test segments by a small margin. No interaction affects were found between mobile devices and text segmentation. These findings challenge the findings of some earlier studies that laptops may be better for learning than smartphones because of screen size, landscape orientation is better for learning than portrait orientation in small screen mobile devices, and meaningful text segments may be better for learning than non-meaningful, non-segmented, or overly segmented text. The results of this study suggest that customizing the design to the smartphone screen (as opposed to a one-size-fits-all approach) improves learning from smartphones, making them equal to learning from laptops in terms of learning outcomes and cognitive load, and in some cases, user perspective.Item EDDE : a framework to explore, design, develop and evaluate technology-enhanced instruction for construction(2010-12) Nguyen, Thuy Thi Thu, Ph. D.; O'Brien, William J.; Bias, Randolph G.; Caldas, Carlost H.; Engelhardt, Michael D.; Julien, Christine L.; Thomas, Stephen R.Technology-enhanced instruction has a great potential to support the learning process. However, the engaging power of technology can become a distracting factor if it is not deployed properly. Unfortunately, the current literature in instructional design and user interface design is broad and not easily accessible by construction faculty. This dissertation presents a framework to guide the development of technology-assisted instruction for the classroom. The framework developed is called EDDE which stands for four conceptual steps involved in the creation of a technology-supported teaching tool: Explore, Design, Develop, and Evaluate. EDDE contains a novel synthesis of the literature in instructional design and user interface design as well as survey data of student subject matter knowledge and information technology background. A computerized tool called EDDEaid makes accessible the large store of knowledge supporting EDDE. Assessment of EDDEaid is presented with evaluation results from nine university faculty that teach construction subjects as well as through critique of and changes to an existing interactive learning tool. EDDE and EDDEaid are found to contribute to the body of knowledge regarding the deployment of technology-enhanced instruction and provide support to construction faculty developing learning tools.Item Faculty change for disciplinary literacies instruction : effects of cognitive modeling as an instructional strategies in online professional development(2014-05) Read, Michelle Fulks; Hughes, Joan E.; Svinicki, Marilla D., 1946-This mixed-methods case study centered on an online professional development (PD) event targeting university-level teacher educators and higher education discipline-specific instructors. The topic of the online PD was disciplinary literacy and the promoted use of metacognitive modeling via think-aloud as an instructional strategy for secondary students in various discipline areas. The study aimed to understand how the use of the same instructional strategy by the PD facilitators affected participants in terms of changes to (a) their knowledge about and attitudes towards reading instruction in the disciplines (e.g., mathematics, social studies, science, the arts); (b) their beliefs regarding learner-centered/non learner-centered classrooms; (c) their general teaching philosophies; and (d) their self-efficacy to use and teach the strategy to others. Specifically, it looked for any relationships between these changes, their intention to apply the same instructional strategy in their own classes and/or teach their pre- and in-service teachers the strategy, and participant perceptions on the importance of the strategy to their learning. The online PD was accessible over a period of four weeks in the winter/spring of 2012. Ten participants from various institutions took part in this study by completing surveys, submitting metacognitive modeling samples pre- and post- PD, and participating in interviews. All participants experienced change during this PD event through the acquisition of new knowledge, while many showed resultant changes to their attitudes and beliefs. Changes in knowledge were most evident in the pre- and post- metacognitive modeling samples the participants provided, with increased scores indicating improvement in their ability to use the instructional strategy. Most evidence of other change is found throughout their interviews. Overall, the participants rated and ranked the metacognitive modeling example videos provided by the PD facilitators as nearly integral to their learning. The largest limitation of the study was the small number of participants. Discussion discerns the nature of teacher change, provides suggestions for future PD design/research, and asserts that the goal of PD, traditionally to result in changed teaching practices in the classroom, instead be to provide the knowledge and initial experience educators can use as a foundation to change in all areas.Item Jobsite information processing : cognitive analysis of construction field managers and applications(2013-08) Mondragon Solis, Fernando Alberto; O'Brien, William J.Field managers have a complex job that requires coordinating a large number of variables that affect construction work. This makes their job primarily abstract, which complicates the observation of their activities; in turn, their knowledge is usually organized in a way that does not adequately consider the relationships between these work variables. As such, practical approaches to aid field managers’ work have often neglected these relationships and have been insufficient to aid practitioners’ coordination tasks. For example, many information tools have been developed to support decisions in the field, but their tendency to separate work activities makes it complicated to integrate the tools into work. Similarly, education programs often focus on individual concepts and tasks, which do not match the practical organization of work activities in the field. This dissertation presents the development of comprehensive cognitive models of field managers to gain insight into the approaches of expert practitioners to address the relationships between the major variables of work. Using the Applied Cognitive Work Analysis (ACWA) technique, it is possible to model work in terms of goals, decisions and information requirements of the job. These components are utilized to explain how the variables of work relate to each other and how they contribute towards attaining the objectives and responsibilities of the job. In particular, the inclusion of activities and tools as part of this set of variables gives insight as to how goals are attained through such means. The cognitive model obtained is applied to, first, analyze the integration of information tools into field managers’ work and, second, analyze the utilization of cognitive models to develop instructional programs and tools. As such, this dissertation makes three main contributions. The first contribution is the development of thorough cognitive models of field managers’ work. The second contribution is the use of these models to consider cognitive and behavioral aspects of adoption of information tools in the field. And the third contribution is the use of these models to present field management learners with the opportunity to use the knowledge and approaches of field managers in a robust learning environment.Item Meeting students' needs and expectations in a culturally diverse e-learning environment : a case study(2010-12) Pham, Minh Trung; Liu, Min, Ed. D.; Cummings, Wm. Theodore; Hughes, Joan; Northcutt, Norvell; Resta, Paul E.The increased growth of online instruction has been well documented by various studies. As the result of the proliferation of online instruction, students from outside of the United States are now able to obtain an American education without having to leave their home country. While online course designs have been well researched and documented to identify best methods and practices to enable optimum learning achievement, providing online instruction to non-US educated students generates the question of how a culturally diverse student body adapts and/or adjusts to an American-style instruction. The purpose of this study is to conduct an exploratory qualitative research to investigate how students from an Asian learning culture adapt to an American online learning environment and to determine whether the various instructional design theories and practices that are widely accepted as best practices in the United States and incorporated into the instruction designs for this Marketing Management hybrid course are also as well-received by students from a different learning culture. From the five categories emerged from the research data: (1) students’ background, (2) perceived benefits, (3) essential skills, (4) supports expected and/or received, and (5) sense of community, the researcher proposed a framework that encompasses the students’ process of adapting to online learning. Within the process of adapting to online learning, conditions such as students’ backgrounds and expectations influenced the various learning strategies that students adopted in order to realize the benefits from the online learning experience. Information gathered from this study may provide those involved in online education - decision makers in academic, business, and professional organizations considering an overseas online instruction strategy - an added awareness of how different learning cultures may influence the quality of an online learning experience. Additionally, for a specific target audience, this research study may further validate the learner-centered approach for instruction designs. For students who may be contemplating online learning as an option, this study may provide a deeper understanding of what is entailed in an online learning environment - the contributing actors and factors that affect the quality of an online learning experience.Item Web-based instruction : the effect of design considerations on learner perceptions and achievement(2000-08) Jones, Colleen McBride; Liu, Min, Ed. D.Web-based instruction provides a new medium for the presentation of instructional activities. In the development of web-based instruction, the designer must realize that the instructional media are merely vehicles for the exchange of ideas. The medium has the capability of addressing individual preferences and styles of learning through its structure and the use of multiple forms of media. Through careful design and adherence to the objectives of instruction and to learners' needs, web-based instruction can provide a successful environment for a variety of learners. In web-based instruction, the design should not be transferred just from one medium to another, but the experience should be redefined with the capabilities of the new medium utilized. Instructional designers must capitalize on the new opportunities that the web provides to learners--to access information from remote locations, to interact with the instruction, to access the instruction at their own pace, to visualize the instruction, and to see the complex relationships in the instruction (Alexander, 1995). Factors in the hypermedia environment, such as visualization, as well as individual student characteristics, such as goal orientation, achievement, and perception, must be taken into account, so the design of web-based instruction enhances the educational opportunities of the learners. ThermoNet was envisioned as a comprehensive supplement for introductory mechanical engineering students. Utilizing many forms of visual media, such as animations, graphics, and video, students would have unlimited access to an interactive web-based environment. This study had four objectives: (1) to determine what students’ characteristics predicted achievement in thermodynamics, (2) to determine what student characteristics predicted the amount of time students spent engaged in ThermoNet, (3) to determine what characteristics impacted students' perceptions of ThermoNet, and (4) to explain the benefits of a web-based instructional environment. The results of this study reveal that web-based instruction may not have a direct impact on students, but the students' goal orientation and preferred mode of learning may impact their achievement. Also, these student characteristics may impact the learner's perception of web-based instruction. More importantly, the results divulge important insights into how web-based instruction can be designed to be a successful learning environment.
