Accuracy on assessments is commonly studied in education research but response time (RT) is relatively less investigated even though decades of research in cognitive sciences indicate that time can be an important dimension for understanding student learning. To better understand RT and the potentially important relations between accuracy and RT…

Algebraic thinking and strategy flexibility are essential to advanced mathematical thinking. Early algebra instruction uses 'missing-operand' problems (e.g., x - 7 = 2) solvable via two typical strategies: (1) direct retrieval of arithmetic facts (e.g., 9 - 7 = 2) and (2) performance of the inverse operation (e.g., 2 + 7 = 9). The current study…

Based on research identifying relations between math and music, we aimed to identify the group of cognitive and affective factors related to math and music theory that best explained undergraduate music theory achievement. Using dominance analysis, we predicted the music theory course grades of 230 undergraduate music majors. Potential predictors…

The purpose of this study was to determine if the Summit Learning Platform, a type of Intelligent Tutoring System, has a positive association with mathematics achievement of high school students in grades nine through eleven. The study was conducted in a Midwest suburban school district among three high schools within the same district. Further, a…

Undergraduate attrition from science, technology, engineering, and mathematics is well documented and generally intensifies during intermediate years of college. Many contributing factors exist; however, a mismatch between timing of certain pedagogical approaches, such as case-based learning, and the level of students' cognitive abilities plays a…

This dissertation studies different social factors that affect students' cognitive, non-cognitive skills, and behaviors. The first chapter provides evidence on the immediate effects of exposure to violent crimes on academic performance and externalizing behaviors among high school students. I find that exposure to violent crimes decreases PSAT,…

Many studies have demonstrated that testing students on to-be-learned materials can be an effective learning activity. However, past studies have also shown that some practice test formats are more effective than others. Open-ended recall or short answer practice tests may be effective because the questions prompt deeper processing as students…

Computer-based testing is an expanding use of technology offering advantages to teachers and students. We studied Calculus II classes for science, technology, engineering, and mathematics majors using different testing modes. Three sections with 324 students employed: paper-and-pencil testing, computer-based testing, and both. Computer tests gave…

Comprehensive understanding of complex biological systems necessitates the use of computational models because they facilitate visualisation and interrogation of system dynamics and data-driven analysis. Computational model-based (CMB) activities have demonstrated effectiveness in improving students' understanding and their ability to use and…

The purpose of this study was to investigate if there are differences in how cognitive and noncognitive variables predict academic performance for college students with learning disabilities. In particular, this study examined the extent to which the cognitive variables of high school grade point average and SAT (combined verbal and math) or ACT…

This report describes several of the design decisions underlying ACT, a production system model of human cognition. ACT can be considered a high level computer programming language as well as a theory of the cognitive mechanisms underlying human information processing. ACT design decisions were based on both psychological and artificial…

The study reported in this paper is designed to provide evidence of the convergent and discriminant validity of the Flexible Combination Test (R. Dillon). Two premises were tested: (1) flexible combination accounts for significant variation in cumulative grade-point average, high school rank, and cumulative Act Assessment scores; and (2) the…

The purpose of this study was to determine if academic achievement differed among the Piagetian cognitive levels of teacher education students and if these differences interacted with sex, age, classification (e.g., freshmen, sophomores), or ACT scores. Sample for the study consisted of 670 students enrolled in a developmental psychology class.…

This paper presents an information processing model of test anxiety in an attempt to explain the mechanism of test anxiety's effect on working memory within the framework of the American College Testing Program Assessment (ACT). The model suggests that the construct of test anxiety, both worry and emotionality, is represented in the declarative…

Differences in critical thinking between undergraduate and graduate students in the social and mathematical sciences was investigated using multiple measures of critical thinking that reflect different types of problem structure. Educational level and academic area differences were found across measures. (Author/MLW)
