This report describes the process of developing and validating the enhanced ACT. The report describes the changes made to the test content and the processes by which these design decisions were implemented. The authors describe how they shared the overall scope of the enhancements, including the initial blueprints, with external expert panels,…

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…

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,…

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 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…

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,…
