Item Investigating the efficacy of a collaborative evaluation model using visual research methods and concept mapping strategies to evaluate a professional learning program for teachers building competency in media literacy(Montana State University - Bozeman, College of Education, Health & Human Development, 2021) Vradenburg, Nicole Angeline; Chairperson, Graduate Committee: Sarah PenningtonThe purpose of this study was to investigate the efficacy of collaborative evaluation as a method for understanding and describing how a collaborative professional learning program for educators will improve their self-reported skills in media literacy while engendering them to deliberately employ media literacy practices in their lesson plans. The model investigated for this study had six phases and employed the use of surveys, collaborative discussion, and the creation of visual artifacts to gather descriptive data to answer research questions. This participatory approach to evaluation gave participating teachers the opportunity to evaluate the data alongside the researcher. The role of the researcher as the program evaluator and facilitator leveraged the collegiality and strong relationships developed over time to gather detailed data about the professional learning program and the self-reported growth in media literacy competency of the teachers. Facilitators of professional learning for teachers can employ a collaborative evaluation model to gather testimony form participants describing their experiences that will inform the design of future programs for teachers. Findings suggest that including teachers in the evaluation of the programs in which they participate is an effective evaluation strategy that increases the chances that the data collected will inform the future professional learning programs for teachers. This model is recommended for programs that are meant to support teachers in building their competency in a specific content area, such as media literacy, over time through collaboration with peers.Item Concept mapping as an assessment of cognitive load and mental effort in complex problem solving in chemistry(Montana State University - Bozeman, College of Education, Health & Human Development, 2018) Shawli, Ahmed Shukri; Chairperson, Graduate Committee: Michael BrodyThis research is an exploratory, descriptive study of students' cognitive load and mental effort related to complex problem solving in high school chemistry. From a cognitive point of view, the complexity associated with problem solving in chemistry can be understood from the context of cognitive load theory (CLT). The objective of this descriptive research using five high school student case studies is to understand the cognitive load phenomena students encounter while learning subject matter that requires complex problem solving, specifically chemical equilibrium. This study employed a mixed methods multiple case study design, in which each participating student (n = 5) is conceptualized as a case. Each student case self-reported their mental effort on eight chemical equilibrium problems. The mean for each students' mental effort and problem solving was reported. Each student completed an equilibrium concept map which was scored. The concept map scores are reported. The analysis compared mental effort score, quiz score and concept map score. There was an inverse relationship between mental effort and concept map score. The more complex the concept map (higher score) the less mental effort students report using to solve the problems. There was a positive relationship between mental effort score and quiz score; and a negative relationship between concept map score and quiz score. We believe these correlations indicate that the variables are related to cognitive load. Methodologically, we found that concept mapping is a valid assessment of cognitive load and mental effort. We believe that further larger studies are needed to substantiate these findings and explain how concept mapping can be used as a representation of cognitive load and student learning.
