The Effect Of Virtual Labs On High School Student Attitudes Towards Chemistry, Emily Koehler
The Effect Of Virtual Labs On High School Student Attitudes Towards Chemistry, Emily Koehler
Dissertations, Theses, and Projects
This mixed-methods action research project evaluated high school chemistry student attitudes towards chemistry before and after the students completed a virtual laboratory. Students were surveyed by utilizing the Attitude Toward the Subject of Chemistry Inventory (Bauer, 2008) and a random sample of students were interviewed by the author. Survey scores in five subscales (emotional satisfaction, anxiety, intellectual accessibility, interest and utility, and fear) were compared through statistical analysis of mean, standard deviation, and t-test. Student attitudes were not significantly different before and after the virtual laboratory experience but did show a general decrease in perceptions of interest and utility of …
Investigating The Attitudes, Beliefs And Practices Of High School Chemistry Teachers Regarding The Differentiation Of Instruction, Anna Tyrina
Electronic Theses and Dissertations
Differentiation of instruction (DI) is a broad term used for a group of pedagogical tools that teachers use to individualize instruction for students of different abilities and needs. Differentiation of instruction is a practice that has been researched and characterized to have a variety of instructional benefits, some of which include increased student motivation and engagement (Tomlinson, 2001). This study sought to characterize the attitudes, beliefs, and practices of ten high school chemistry teachers in Maine regarding the differentiation of instruction. Through a phenomenological approach, interviews with these teachers were analyzed to understand how high school chemistry teachers define differentiated …
The Activity Of Abstraction In Physical Chemistry Problem Solving And Instruction, Jessica M. Karch
The Activity Of Abstraction In Physical Chemistry Problem Solving And Instruction, Jessica M. Karch
Graduate Doctoral Dissertations
Productive problem solving, concept construction, and sense making occur through the core process of abstraction. Although the capacity for domain-general abstraction is developed at a young age, the role of abstraction in increasingly complex and disciplinary environments, such as those encountered in undergraduate STEM education, is not well understood. Undergraduate physical chemistry relies particularly heavily on abstraction because it uses many overlapping and imperfect mathematical models to represent and interpret phenomena occurring on multiple scales. To reconcile these models, extract meaning from them, and recognize when to apply them in problem solving requires processes of abstraction. This dissertation aims to …
