Decision Making In The Sciences: Understanding Heuristic Use By Students In Problem Solving, Elizabeth Csikar

STEMPS Theses & Dissertations

The purpose of this study was to examine the use of heuristics by students and gain insight into the thought process behind their problem-solving skills. The study used an adaptive narrative as the information delivery medium. An adaptive narrative was chosen because it could be designed to simulate decision making processes encountered in real world situations. Students enrolled in an introductory biology major class were chosen for the study because their fields of interest all require complex problem solving and decision-making skills. It was of interest to investigate what decisions were made when heuristics were given and how that may …

Instructional Designer Awareness And Application Of Strategies To Manage Cognitive Load, Justin A. Sentz

STEMPS Theses & Dissertations

This study examined how practicing instructional designers manage cognitive load in a standardized scenario as they select and implement instructional strategies, message design, content sequencing, and delivery media within various domains with learners at different levels of expertise. The study employed a quasi-experimental, mixed methods design to gain insight into how practicing instructional designers perceive their awareness of strategies to manage cognitive load and implement those strategies within a standardized design scenario. The research design involved the collection of quantitative data from the participants during an initial web-based questionnaire and a second collection of both quantitative and qualitative data as …

Investigating Application Of The Self-Explanation Learning Strategy During An Instructional Simulation, Paul Michael Macloughlin

STEMPS Theses & Dissertations

Computer-based simulations effectively support the acquisition of scientific knowledge when combined with a guided learning approach. Active learning drives complex cognitive processes that enable the integration of new information with existing knowledge. The iCAP (Interactive, Constructive, Active, Passive) Framework provides a conceptual model to describe different types of active learning. Computer-based simulations fit neatly within this framework. Similarly, self-explanation is a generative learning strategy that fits within this framework. Promoting self-explanation using instructional prompts is an effective method for driving application of the strategy. This study compared three combinations of self-explanation prompt and learner activity (closed prompts – overt activity, …

Exploring The Effects Of Pacing In Community College Courses, Robin Dillon Shepherd

STEMPS Theses & Dissertations

For-profit colleges are threatening community college enrollments by recruiting low-income and minority students with the appeal of quick degree and certificate program completion rates. To remain competitive, community colleges are creating guided pathways for student success. A guided pathway is a clear road map to certificate or degree completion. Community colleges that offer guided pathways challenge students to choose an academic program in their first semester and no later than their second semester. Once students choose their academic program they begin taking specific classes in pursuit of certificate and degree completion, which offer students flexibility in format (face-to-face, hybrid, and …

Reimagining The Chalk Talk: Animated Handwriting As A Social Cue To Improve Motivation In Multimedia Video Lessons, Hillary C. Kaplowitz

STEMPS Theses & Dissertations

Animated handwriting in multimedia video lessons, such as those popularized by the Khan Academy, has reimagined the classic teaching technique of writing on a chalkboard while lecturing for online delivery. This digital chalk talk effect mimics classroom lectures where words are written letter by letter on a chalkboard as they are spoken. Low-cost applications, tablets, and document cameras allow instructors at all levels to easily create their own animated handwritten videos. As adoption increases, it is important to understand the effects of this strategy.

This study employed a true experimental, between-subjects, posttest design that compared multimedia lessons with different text …

The Effect Of Emotive Content On Knowledge Acquisition And Ethical Sense Making Using An Ill-Structured Case Example, Tina M. Souders

STEMPS Theses & Dissertations

Social workers encounter ethics related challenges on a daily basis. These real-world problems are incredibly complex and can produce intense emotional reactions. The use of ill-structured case examples as an instructional strategy to teach ethical lessons is well-supported in the literature, however, case examples often lack an emotional or affective component. Given the importance of crafting cases for learners, more research is needed to better understand how to construct and present case examples to enhance learning outcomes, specifically related to the influence of emotive content. This study was conducted to assess the effect of emotive content on knowledge acquisition and …
