Characterizing Students’ Thinking: Algebraic Inequalities And Equations, Kien H. Lim
Characterizing Students’ Thinking: Algebraic Inequalities And Equations, Kien H. Lim
Kien H Lim
This paper presents the findings of a study that explores the viability of using students’ act of anticipating as a means to characterize the way students think while solving problems in algebra. Two types of anticipating acts were identified: predicting a result and foreseeing an action. These acts were characterized using Harel’s framework, which involves the concepts of mental act, way of understanding, and way of thinking. Categories for characterizing acts of predicting and foreseeing were identified and developed based on thirteen 11th graders’ responses to problems involving algebraic inequalities and equations. The quality of students’ acts of predicting and …
Second Graders' Solution Strategies And Understanding Of A Combination Problem, Tiffany Marie Hessing
Second Graders' Solution Strategies And Understanding Of A Combination Problem, Tiffany Marie Hessing
Theses and Dissertations
I inquire about second graders' capabilities of developing solution strategies and the original variety of strategies they bring forth while solving a combination problem. Based on analysis of the data presented in this paper, students developed five different general strategies. After analyzing what the second grade students were capable of developing, we can conclude that young children are capable of developing powerful systematic strategies grounded in their personal experiences. This research shows that even when the teacher does not foster personal agency, children will still exercise agency. The social interactions in the classroom helped students learn to propose mathematical ideas, …
Classroom Mathematical Practices In A Preservice Elementary Mathematics Education Course Using An Instructional Sequence Related, Janet Andreasen
Classroom Mathematical Practices In A Preservice Elementary Mathematics Education Course Using An Instructional Sequence Related, Janet Andreasen
Electronic Theses and Dissertations
This qualitative study documents a classroom teaching experiment in a semester-long undergraduate mathematics education course for 16 prospective elementary school teachers. The purpose of this study was to investigate how social aspects of the classroom environment facilitated the collective mathematical learning of place value and whole number operations by preservice elementary school teachers. Design-based research methodology was used for formulating the study. A hypothetical learning trajectory and instructional sequence related to place value and operations were created and refined in the two semesters prior to this study. The instructional sequence was in its third iteration for this study. The developmental …
Students’ Mental Acts Of Anticipating In Solving Problems Involving Algebraic Inequalities And Equations, Kien Hwa Lim
Students’ Mental Acts Of Anticipating In Solving Problems Involving Algebraic Inequalities And Equations, Kien Hwa Lim
Kien H Lim
Anticipating is the mental act of conceiving a certain expectation without performing a sequence of detailed operations to arrive at the expectation. This dissertation seeks to characterize students’ problem-solving in terms of two types of anticipating acts: (a) foreseeing an action, which refers to the act of conceiving an expectation that leads to an action, prior to performing the operations associated with the action, and (b) predicting a result, which refers to the act of conceiving an expectation for the result of an event without actually performing the operations associated with the event. Harel’s (in press) triad of determinants—mental act, …
Technology Professional Development: Long-Term Effects On Teacher Self-Efficacy, George R. Watson
Technology Professional Development: Long-Term Effects On Teacher Self-Efficacy, George R. Watson
Educational Foundations and Technology
The West Virginia K-12 RuralNet Project was an NSF funded program to train inservice teachers on integrating the Internet into science and mathematics curriculum. The program involved training inservice teachers through an intensive summer workshop and supplemental online courses. This study examines the effects of the project on the long-term self-efficacy of inservice teachers and their use of the Internet in the classroom. The specific research questions addressed are: Do professional development programs affect the long-term self-efficacy of inservice teachers? Did the addition of online courses and follow-up to the program affect self-efficacy levels? Finally, do certain external factors, specifically …
An Examinition Of Competencies, Roles, And Professional Development Needs Of Community College Distance Educators Who Teach Mathematics, Falecia Williams
An Examinition Of Competencies, Roles, And Professional Development Needs Of Community College Distance Educators Who Teach Mathematics, Falecia Williams
Electronic Theses and Dissertations
This study describes the perceptions of both distance education administrators and faculty who teach mathematics online in a Florida community college setting with regard to the relative importance of core competencies and roles in teaching online courses and the need for professional development that is supportive of these competencies and roles. The perceptions of administrators and online faculty for level of importance indicated for core competencies and skill area needs for faculty development when teaching an online course were examined. Results of these perceptions by group were re-examined in relation to gender, age, ethnicity, years of community college teaching experience, …
