Recently, Nissen et al. argued in this journal for the use of Cohen's d, in place of the more commonly used normalized gain, in the analysis of preinstruction and postinstruction scores on concept inventories used to measure the effectiveness of instruction. Their reason for advocating such a change is that they say normalized gains are…

As test preparation becomes widely accessible through different delivery systems, large-scale studies of test preparation efficacy that involve a variety of test preparation activities become more important to understanding the value and impact of test preparation activities on both the ACT and SAT. In this paper, the authors examine the impact of…

General chemistry are key gateway courses for many Science, Technology, Engineering, and Mathematics (STEM) majors. To improve student outcomes, it is critical both to identify at-risk students and implement evidence-based instructional strategies and interventions. These remain active areas of investigation, with recent literature showing that…

Over the last decade, the "gender gap" in physics conceptual inventory scores has been extensively studied by the physics education research community. Researchers have identified many factors that influence the overall differences in post-test scores between men and women. More recently, it has been shown that the Force Concept…

This study compared the effect of two notetaking strategies (Cornell Notes vs. REAP) on EFL secondary school students' critical reading skills. The Alternative Treatment Design with Pretest was used where three intact classes of first-year EFL secondary school students were randomly assigned as a control group and two experimental groups. All…

Determining student readiness for gateway chemistry courses and providing underprepared students effective remediation are important as student bodies are growing increasingly diverse in their precollege preparation. The effectiveness of the ACT Mathematics Test and the Whimbey Analytical Skills Inventory (WASI) in predicting student success in…

This study aims to investigate the effectiveness of the Emporium instructional method in a course of college algebra and trigonometry by comparing to the traditional lecture method. The math emporium method is a nontraditional instructional method of learning math that has been implemented at several universities with much success and has been…

In this study, we examined academic outcomes among students from low-income and academically disadvantaged backgrounds who participated in the Educational Opportunity Program (EOP) at a selective four-year public comprehensive college in the Northeast. We found that provisionally admitted EOP students earned comparable first-semester grades and…

Critical to many science, technology, engineering, and mathematics (STEM) career paths is mathematical modeling--specifically, the creation and adaptation of mathematical models to solve problems in complex settings. Conventional standardized measures of mathematics achievement are not structured to directly assess this type of mathematical…

This mixed methods counterbalanced study compared the gain score means of two different approaches to vocabulary acquisition--Vocabulary Theater (VT) and Teacher Directed Instruction (TDI) for 8th grade students from three schools in New York. The purpose of the study was to explore the effects of a peer teaching approach on students' vocabulary…

College algebra fulfills general education requirements at many colleges in the United States. The study reported here investigated differences in mathematics achievement between undergraduates in college algebra classes using one of two homework methods: "WeBWorK," an open-source system for web-based homework, or traditional…

The effects of clicker-use and active learning classroom activities on student performance in financial accounting principles were examined. A repeated measure design was used to compare performance on four exams between a clicker group and a non-clicker group, after controlling for GPA and age. A matched-pairs t-test was used to compare the…

In this article, the author explores the idea that reading proficiency in a second language involves comprehending the second culture and using it to interpret the world view of the second language. Using cognitive theory, the author examined the relevance of prior knowledge of Chinese language and idioms to understanding text written in Chinese.…

This discussion paper represents one of the National Association for College Admission Counseling's (NACAC's) first post-Testing Commission steps in advancing the knowledge base and dialogue about test preparation. It describes various types of test preparation programs and summarizes the existing academic research on the effects of test…

Despite the growing use of writing assessments in standardized tests, little is known about coaching effects on writing assessments. Therefore, this study tested the effects of short-term coaching on standardized writing tests, and the transfer of those effects to other writing genres. College freshmen were randomly assigned to either training…
