Law enforcement officers can come into conflict with suspects when they need to act fast under time pressure. Improving such a decision-making skill is a challenge in a police academy. Academies can train future officers in correct psychomotor responses to attacks by a suspect. However, the ability to anticipate such attacks, and thereby make more…

This dissertation describes an experiment to investigate how learners with different levels of background in computer science learn core concepts of computer science, in particular, algorithms. We designed a study to focus on cognitive task analysis for eliciting the empirical mental elements of learning two graph algorithms. Cognitive workload…

Though the No Child Left Behind Act of 2001 requires secondary students with Asperger's syndrome (AS) to take high-stakes mathematical tests, many students with AS exhibit weaknesses in mathematical and executive functioning skills. The purpose of this mixed-methods case study was to explore the use of differentiated mathematical strategies with…

Research shows that mental representation such as analogical reasoning is a fundamental cognitive tool for design problem solving (Daugherty & Mentzer, 2008; Hey, Lensey, Agogino, & Wood, 2008; Lewis, 2008). Not much is known, however, about the way students and professional engineers actively generate and change their mental representation when…

Researchers have been able to link working memory to many important cognitive abilities throughout the life span. Two of the unanswered questions about working memory are what cognitive processes function during working memory task performance and how do these processes directly relate to intelligence? A recent model (Unsworth & Engle, 2006)…

An increased number of students graduating from high school lack college and career readiness skills to earn credit in entry-level college courses or begin a career in an entry-level position. Many schools across America have prepared to address students' college and career readiness with the adoption of Common Core State Standards. Twenty-five…

The ability of tenth grade plane geometry students to structure concepts and relationships from a geometry unit on ratio, proportion and similarity was tested. Analysis of cognitive "maps" of the structural relationships possessed by twenty concrete and twenty formal subjects indicated that formal operational subjects structure subject…

Based upon Ausubel's theory of meaningful learning, this study focused on the use of concept maps (diagrams that portray relationships among concepts in a given area of study) to help students identify logical relationships between a new concept and concepts already known. Relationships of a learner's prior knowledge and cognitive development to…

Recent research has begun to suggest that epistemological beliefs of students develop to a more sophisticated level with age and education, while other preliminary studies have found that community college students tend to have more naive beliefs about learning and knowledge than do students attending four-year colleges and universities. The…

This study describes the relationship of two cognitive variables, logical thinking and disembedding ability, to learners' abilities to make conceptual shifts from less acceptable to more acceptable conceptual understandings of a physical phenomenon. The difference in the logical thinking and disembedding ability of students who exhibited different…

This study develops and employs the construct, personal orientation to science learning, to study the processes by which children construct meaning as they learn science in school. The theoretical bases of the thesis are the commitments of a constructivist view of learning and the psychological framework of George Kelly's Personal Construct…

After observing secondary school students having great difficulty learning geometry in their classes, Dutch educators Pierre van Hiele and Dina van Hiele-Geldof developed a theoretical model involving five levels of thought development in geometry. It is the purpose of this monograph to present English translations of some significant works of the…

This study was designed to investigate the relationship between the level of conservation of displaced volume and the degree to which sixth-grade children learn the volume algorithm of a cuboid, namely, volume equals weight times length times height. The problem chosen is based on an apparent discrepancy between the present school programs and…
