Investigating Active Learning Through The Lens Of Student Engagement, Nicole Naibert

Dissertations and Theses

Incorporating active learning into a course has been generally found to lead to improved student learning outcomes; however, not all students benefit from these environments to the same extent. Although active learning environments provide the opportunity for students to interact and engage with the material, whether a student decides to do so is completely up to them. Therefore, the goal of this dissertation was to begin exploring active learning environments through the lens of student engagement and relevant associated variables (i.e., self-efficacy and student perceptions). This was completed through three separate but related projects.

Project I focused on investigating flipped …

Assessing The Efficacy Of Virtual Experiments In The General Chemistry Laboratory, Cory Jerome Hensen

Dissertations and Theses

As more students enroll in chemistry courses, institutions are faced with increasing costs and limited laboratory space to keep up with the demand. One solution some institutions have turned to is the incorporation of virtual experiments into the curriculum, as this can lower costs and increase the availability of laboratory space. Some institutions have offered sections that complete all of their experiments in a virtual environment, others have offered sections that alternate between a traditional hands-on experiment and a virtual experiment, and some institutions have replaced only select experiments throughout the curriculum with a virtual experiment. To begin to be …

Connecting Chemistry To Community With Deliberative Democracy, Regis Komperda, Jack Barbera, Erin Shortlidge, Gwen Shusterman, Stem Education And Equity Institute, Portland State University

Biology Faculty Publications and Presentations

Science education communities have called for rethinking curricula to improve student understanding of the nature of science and the role of science in addressing controversial modern issues such as climate change, energy policy, and pollution levels. One approach to meeting this call is integrating these topics into class activities that require students to use discussion and scientific approaches to solve problems and deliberate potential policy solutions. Deliberative democracy (DD) is one such active learning approach in which students work in peer groups to reach a consensus on a scientific topic relevant to both real-world issues and course content. During DD …

Exploring Students' Perceptions And Performance On Predict-Observe-Explain Tasks In High School Chemistry Laboratory, Praveen Vadapally

Dissertations

This study sought to understand the impact of gender and reasoning level on students’ perceptions and performances of Predict-Observe-Explain (POE) laboratory tasks in a high school chemistry laboratory. Several literature reviews have reported that students at all levels have not developed the specific knowledge and skills that were expected from their laboratory work. Studies conducted over the last several decades have found that boys tend to be more successful than girls in science and mathematics courses. However, some recent studies have suggested that girls may be reducing this gender gap. This gender difference is the focal point of this research …

Development And Evaluation Of A Thermochemistry Concept Inventory For College-Level General Chemistry, David A. Wren

Dissertations

The research presented in this dissertation culminated in a 10-item Thermochemistry Concept Inventory (TCI). The development of the TCI can be divided into two main phases: qualitative studies and quantitative studies. Both phases focused on the primary stakeholders of the TCI, college–level general chemistry instructors and students. Each phase was designed to collect evidence for the validity of the interpretations and uses of TCI testing data. A central use of TCI testing data is to identify student conceptual misunderstandings, which are represented as incorrect options of multiple– choice TCI items. Therefore, quantitative and qualitative studies focused heavily on collecting evidence …

Design, Development, And Psychometric Analysis Of A General, Organic, And Biological Chemistry Topic Inventory Based On The Identified Main Chemistry Topics Relevant To Nursing Clinical Practice, Corina E. Brown

Dissertations

This two-stage study focused on the undergraduate nursing course that covers topics in general, organic, and biological (GOB) chemistry. In the first stage, the central objective was to identify the main concepts of GOB chemistry relevant to the clinical practice of nursing. The collection of data was based on open-ended interviews of both nursing and chemistry teaching faculty as well as practicing nurses. From the resulting interviews, three themes emerged: topics that were Important--had a direct application in nursing clinical practice; topics that were Foundational--not directly important for nursing clinical practice but facilitated the understanding of the important topics; and …

A Study Of Critical Incidents Relating To Effective Instruction In Secondary School Physics, Chemistry, And Biology, Ernest Solomon Palmer

All Master's Theses

The purpose of this study is twofold. First, to compile a list of factors aiding in the effectiveness of instruction in secondary school chemistry, physics, and biology classes, and second, to determine whether or not these factors aiding effectiveness have elements in common. The problem will then be to characterize these common elements.
