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 …
Analysis Of English Language Learner Performance On The Biology Massachusetts Comprehensive Assessment System: The Impact Of English Proficiency, First Language Characteristics, And Late-Entry Ell Status, Mary A. Mitchell
Graduate Doctoral Dissertations
This study analyzed English language learner (ELL) performance on the June 2012 Biology MCAS, namely on item attributes of domain, cognitive skill, and linguistic complexity. It examined the impact of English proficiency, Latinate first language, first language orthography, and late-entry ELL status. The results indicated that English proficiency was a strong predictor of performance and that ELLs at higher levels of English proficiency overwhelmingly passed. The results further indicated that English proficiency introduced a construct-irrelevant variance on the Biology MCAS and raised validity issues for using this assessment at lower levels of English proficiency. This study also found that ELLs …
The Association Between Elementary Teacher Licensure Test Scores And Student Growth In Mathematics: An Analysis Of Massachusetts Mtel And Mcas Tests, Life Legeros
Graduate Doctoral Dissertations
This quasi-experimental value-added study provided evidence for the predictive validity of the Massachusetts MTEL General Curriculum Mathematics Subtest by finding an association between the licensure test results of 130 teachers and the growth of their 2640 grade 4 and 5 students. The study took advantage of a natural experiment that arose due to a policy change made by the Massachusetts Department of Elementary and Secondary Education (MADESE) in response to the initial administration of a new highly rigorous math-specific licensure subtest for elementary and special education teachers in March, 2008. The emergency amendment allowed test takers to conditionally pass the …
In Students' Words: The Development Of Student Attitudes Toward Mathematics - A Social Perspective, Dianne Kathryn Kelly
In Students' Words: The Development Of Student Attitudes Toward Mathematics - A Social Perspective, Dianne Kathryn Kelly
Graduate Doctoral Dissertations
Student interest in pursuing advanced studies and careers in Science, Technology, Engineering, and Mathematics (STEM) has garnered much attention lately from government, business, and education leaders due to inadequate flow in the United States' STEM pipeline. Existing research points to mathematical self-efficacy and to mathematical self-concept beliefs as integral to the likelihood that a student will pursue a career in a STEM field. Students' identities, such as the "good-math-student" identity need to be verified in order for students to enact them. Both identity verification and attitude are influenced by self-efficacy and self-concept. Existing research also points to teachers, parents, and …
