Changing Perceptions Of Science In Undergraduate Students: A Mixed Methods Case Study, Cindy S. Larson-Miller

Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research

The purpose of this bounded single-case study was to explore the understanding of the nature and process of science for undergraduate students at the University of Nebraska-Lincoln (UNL). The study investigated one professor’s methodology to explicitly teach undergraduate students about the nature and process of science, and documented their understanding and perception of science, both pre- and post-course.

Using a mixed method approach, data were collected to provide a better understanding of teaching the nature and process of science. Three main types of data were analyzed: the process of science (TPOS) assessment; survey questions, and the module curriculum.

Use Of Cognitive Artifacts In Chemistry Learning, Ilker Yengin

Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research

In everyday life, we interact with cognitive artifacts to receive and/or manipulate information so as to alter our thinking processes. CHEM/TEAC 869Q is a distance course that includes extensive explicit instruction in the use of a cognitive artifact. This study investigates issues related to the design of that online artifact. In order to understand design implications and how cognitive artifacts contribute to students’ thinking and learning, a qualitative research methodology was engaged that utilized think aloud sessions. Participants’ described constrained and structured cognitive models while using the artifact. The study also was informed by interviews and researcher's field notes. A …

Extensiveness And Perceptions Of Lecture Demonstrations In The High School Chemistry Classroom, Daniel S. Price

Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research

While lecture demonstrations have been conducted in chemistry classrooms for hundreds of years, little research exists to document the frequency with which such demonstrations are employed or their effect on learners’ motivation and performance. A mixed-methods research study was performed, using quantitative and qualitative survey data, along with qualitative data from follow-up interviews and structured correspondence, to determine the extent to which lecture demonstrations are used in high school chemistry instruction, and the perceived effects of viewing such demonstrations on students’ performance on course assignments and on motivation to excel in current and future chemistry courses. Fifty-two randomly selected chemistry …

Children's Voices: Students' Attitudes About Routine And Nonroutine Mathematics, Deborah E. Seacrest

Department of Teaching, Learning, and Teacher Education: Dissertations, Theses, and Student Research

This dissertation is a case study focused on the question, "What are students' attitudes toward school mathematics and toward nonroutine math problems and mathematical games?" It addresses the definitions of some of those terms and then moves on to a literature review that suggests that some change in the curriculum may be needed. In an attempt to begin determining whether nonroutine problems and mathematical games could help, students in two different types of classes were introduced to such problems and games. Their attitudes were assessed using a variety of methods, including observation, interview, and journal writing.

The games and problems …
