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…

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…

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…

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 study examined the extent to which selected high school academic variables and noncognitive characteristics of American College Testing (ACT)--tested students explain differential test performance of racial/ethnic and gender groups. Of particular interest was the extent to which the noncognitive variables, over and above course work taken,…

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)
