Development And Validation Of The Mathematical Problem-Solving Dispositions And Beliefs Scale, Laura L. Barrett Jul 2016

Development And Validation Of The Mathematical Problem-Solving Dispositions And Beliefs Scale, Laura L. Barrett

Doctor of Education in Secondary Education Dissertations

Mathematical problem solving has received recent attention and been recognized as central to analysis and application in everyday life. Mathematical problem solving has often been characterized by traditional word problems. From the models-and-modeling perspective, students problem solve mathematically by engaging in conceptual development through interaction with communities of practice that produce artifacts that are continually under design. Productive problem-solving dispositions and beliefs mold students who are confident and willing to take on new tasks. Attitudes, feelings, dispositions, and beliefs are manipulatable, and thus individuals’ problem-solving identity is complex. To date, there are no empirical studies that have measured students’ levels ...


Using Manipulatives To Investigate Esol Students' Achievement And Dispositions In Algebra, Donna L. Marsh Jul 2016

Using Manipulatives To Investigate Esol Students' Achievement And Dispositions In Algebra, Donna L. Marsh

Doctor of Education in Teacher Leadership Dissertations

The purpose of this embedded quasi-experimental mixed methods research was to investigate the effectiveness of concrete and virtual manipulatives on the achievement of English Speakers of Other Languages (ESOL) as they employ them to explore linear and exponential functions in high school Sheltered Common Core Coordinate Algebra. Also of interest were the effects concrete and virtual manipulatives have on their disposition towards mathematics and math class. Another goal was to investigate the benefits and disadvantages of using concrete and virtual manipulatives versus traditional instructional practices.

This was a 5-week study. The control group (N=20) was instructed through the use ...
