A Semiotic Analysis Of Linguistic And Conceptual Development In Mathematics For English Language Learners, Hyunsook Shin
A Semiotic Analysis Of Linguistic And Conceptual Development In Mathematics For English Language Learners, Hyunsook Shin
Doctoral Dissertations
This study explores how an elementary mathematics teacher supported English language leaners’ (ELLs’) academic language and concept development in the context of current high- stakes school reform. The conceptual frameworks informing this study include Halliday’s theory of systemic functional linguistics (e.g., Halliday & Matthiessen, 2014) and Vygotsky’s sociocultural theory of concept development (Vygotsky, 1986). Specifically, this study analyzes the interplay between academic and everyday language and how this interplay can facilitate the development of what Vygotsky referred to as “real” or complete concepts as students shift from “spontaneous” to more “scientific” understanding of phenomenon (Vygotsky, 1986, p.173). This year-long qualitative …
Female Students’ Academic Engagement And Achievement In Science And Engineering: Exploring The Influence Of Gender Grouping In Small Group Work In Design-Based Learning Contexts In High School Biology, Miancheng Guo
Doctoral Dissertations
In the past 30 years, although much effort has been made to narrow the gender gap in science, technology, engineering and mathematics (STEM), females are still largely underrepresented in some important STEM fields, such as physics and engineering (NSF, 2007). To deal with this situation, people from different sectors have long reached a common understanding: Educators must improve school girls’ interest, participation and engagement in STEM subjects (e.g., Office of Science and Technology Policy, 2013). In the K-12 classroom, small group work has been shown to promote an equitable environment for girls’ learning in science and have a positive impact …
The Role Of Prior Knowledge, Situational Interest, And Case Study Pedagogy In The Undergraduate Biology Classroom., Ally Hunter
The Role Of Prior Knowledge, Situational Interest, And Case Study Pedagogy In The Undergraduate Biology Classroom., Ally Hunter
Doctoral Dissertations
In the undergraduate science classroom, case study pedagogy is method that uses stories with dilemmas and/or questions to convey scientific content. Case study pedagogy shows promise as an active learning pedagogy to meet the demands of 21st century biology education initiatives; however, there is a dearth of information on how students learn with case studies in the undergraduate biology classroom. The purpose of this study was to investigate variables that impact learning with case studies (prior content and contextual knowledge, situational interest, and pedagogical strategies) and the relationships between those variables to further understand how students learn with case studies …
Multiple Representations Of The Fundamental Theorem Of Calculus As Enacted In The Curriculum, Sense-Making And Gender, Ileana Vasu
Multiple Representations Of The Fundamental Theorem Of Calculus As Enacted In The Curriculum, Sense-Making And Gender, Ileana Vasu
Doctoral Dissertations
Multiple representations of the Fundamental Theorem of Calculus (FTC) are deemed essential to creating mathematical habits of mind, but not all classroom instruction includes them. This study articulates the relationship between college students’ experience with multiple representations of the FTC, gained through the enacted curriculum, and their use of multiple representations when problem solving or discussing the FTC. It suggests that students’ use of multiple representations directly relates to their curricular experience, which outweighs a student’s own inclination towards any particular representation. It further suggests that the relationship between classroom experience with a particular representation of the FTC, and its …
Conditions Supporting The Development Of Scientific Argumentation In High School Chemistry Classrooms: The Role Of Question Prompts And An Interactive Simulation, Tugba Keser
Doctoral Dissertations
The purpose of this case study was to provide benefit to preservice and inservice science teachers, who have an interest in applying scientific argumentation in their high school chemistry instructions, by investigating role of question prompts and an interactive simulation supporting the development of scientific argumentation. In particular, the study examined the quality of students’ arguments changing over time in scientific argumentation when they constructed and defended their arguments using the “Gas Properties” computer simulation. For this purpose, forty-seven11th grade students from four classes first worked in pairs and then, all the pairs returned the classroom for discussion. One …
A Novel Approach To Using Personal Response Systems And Diagrams To Foster Student Engagement In Large Lecture: Case Study Of Instruction For Model-Based Reasoning In Biology, Johanna M. Fitzgerald
A Novel Approach To Using Personal Response Systems And Diagrams To Foster Student Engagement In Large Lecture: Case Study Of Instruction For Model-Based Reasoning In Biology, Johanna M. Fitzgerald
Doctoral Dissertations
At UMass Amherst a method of personal response system (clickers) use in large lecture biology called Guided Application of Model-based Reasoning (GAMBR) has been designed to give students experiences in reasoning like expert biologists: In large lecture biology many instructors appear to use clickers mainly as a quizzing and attendance tool. Less well documented and examined are uses of clickers to facilitate cognitive engagement in learning scientific models and skills. In GAMBR, clicker questions ask students to apply and perturb biological models; this is designed to engage them in model-based reasoning. In an attempt to understand such a course, an …
Developing Spatial Reasoning Skills In General Chemistry Students, Deborah L. Carlisle
Developing Spatial Reasoning Skills In General Chemistry Students, Deborah L. Carlisle
Doctoral Dissertations
The study of organic chemistry requires the understanding and use of spatial relationships, which can be challenging for many students. Prior research has shown that there is a need to develop students’ spatial reasoning skills. To that end, this study implemented guided activities designed to strengthen students’ spatial skills, with the aim of preparing students for organic chemistry and other future STEM courses. Students, taking the second semester of a two-semester general chemistry course, engaged in these activities. This study followed a quasi experimental design, in which the experimental (n = 209) and the control group (n = 212) were …
