This ex-post facto quantitative study examined how a comprehensive STEM education program impacts high school students' ACT math and science scores as well as their attitudes toward STEM. Using data from one STEM-designated school, the researcher examined ACT math, science, and STEM results for students who took the ACT in the Spring of 2024,…

For this project, ACT developed math and science items that attempted to represent unique aspects of cultures, raise awareness of social justice issues, promote cultural learning, be authentic and relatable, be comprehensible, and represent people in positive, nonstereotypical ways. Creating culturally relevant items was a new challenge for ACT…

To examine differences between sequences of secondary science courses on achievement on science high stakes exams, a purposive quantitative research design was utilized in this study. A short survey was sent out to public high schools in the state of Missouri that asked to identify their main science course sequence. In addition, participants were…

Beginning in September 2020, students will have the option to retake one or more sections of the ACT® test (referred to as section retesting, modular testing, or single-subject retesting), instead of needing to take the entire battery again. Section retests will only be available to students who have previously completed the full battery and only…

Previous studies have found that students' concept-building approaches, identified a priori with a cognitive psychology laboratory task, are associated with student exam performances in chemistry classes. Abstraction learners (those who extract the principles underlying related examples) performed better than exemplar learners (those who focus on…

Previously, we had reported on the relationship between AP physics experience and exam scores, and student scores on the Force and Motion Conceptual Evaluation and in an introductory calculus-based mechanics course [E. W. Burkholder and C. E. Wieman, Phys. Rev. Phys. Educ. Res. 15, 020117 (2019)]. Two limitations to our previous work were that we…

Speeded tests set time limits so that few examinees can reach all items, and power tests allow most test-takers sufficient time to attempt all items. Educational achievement tests are sometimes described as "timed power tests" because the amount of time provided is intended to allow nearly all students to complete the test, yet this…

The study endeavored to determine if teaching test-taking strategies had an impact on the students' performance on the ACT science subsection exam. Students received test-taking strategies instruction for the ACT science subsection exam. Students were administered a pre-and post-test, confidence survey, and strategies ranking list. The study also…

The number of applications to postsecondary institutions continues to increase year over year, and in most cases, the number of applications exceeds the number of students admitted. The use of standardized tests continues to grow to help in these admissions decisions. Due to both high usage rates and the changing demographics of our nation's…

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…

Formally launched in September 2018, the ACT® Certified Educator™ program is a professional learning and credentialing program designed to help educators improve their teaching and tutoring strategies and skills and be fully equipped to support student learning in the core content areas of the ACT® test. In this study, participants' views of the…

In recent ACT mode comparability studies, students testing on laptop or desktop computers earned slightly higher scores on average than students who tested on paper, especially on the ACT® reading and English tests (Li et al., 2017). Equating procedures adjust for such "mode effects" to make ACT scores comparable regardless of testing…

Benefits of metacognition and active learning on student performance are well understood; however, little is known about the effect of the "explicit teaching of metacognition" combined with active learning on student performance in chemistry courses. Using a quasi-experimental study design, we investigated: (1) differences in performance…

Here we demonstrate the benefits of a new curriculum for introductory calculus-based physics that motivates classical mechanics using a modified version of Hamiltonian mechanics. This curriculum shifts the initial focus of instruction away from forces and the associated vector mathematics, which are known to be problematic for students, to the…

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…
