The Use Of A Modified Hess’ Cognitive Rigor Matrix To Assess Students’ Depth Of Knowledge In Key Concepts Of Gas Stoichiometry And Chemical Equilibrium, Maria Greene
Dissertations, Theses, and Capstone Projects
The research presented as part of this dissertation is a combination of two separate studies conducted to assess and evaluate undergraduate general chemistry students’ understanding and depth of knowledge (DOK) of concepts in gas stoichiometry and chemical equilibrium. The two separate studies were conducted using a modified Hess Cognitive Rigor Matrix (CRM) to analyze students’ responses to multiple-choice questions (MCQ) and their written rationales to their answer choices. The Hess Cognitive Rigor Matrix, which is an incorporation and coordination of both Bloom’s and Webb’s DOK taxonomies, allowed the facilitation of the opportunity to code students’ written responses across the four …

Mathematics Cognitive And Content Abilities Across The Vincentian Student Population, Brendalee Rorena Cato
Walden Dissertations and Doctoral Studies
Mathematics achievement is a key component of student overall academic achievement. However, many students from Saint Vincent and the Grenadines (Vincentian students) continue to perform poorly on the regional Caribbean Secondary Examination Certificate (CSEC) mathematics examination. This poor mathematics performance is a concern for education stakeholders. The purpose of this quantitative, nonexperimental study was to explore the extent to which the CSEC mathematics scores of high-scoring Vincentian students versus low-scoring Vincentian students in the cognitive domains of knowledge, comprehension, and reasoning differ across the content domains of algebra; geometry; measurement; statistics; and relations, functions, and graphs (RFG). The theoretical foundation …
