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…

Although memory retrieval often enhances subsequent memory, Peterson and Mulligan (2013) reported conditions under which retrieval produces poorer subsequent recall--the negative testing effect. The item-specific--relational account proposes that the effect occurs when retrieval disrupts interitem organizational processing relative to the restudy…

This quantitative ex post facto study investigated the effects of career academies on academic achievement and college readiness. A total of 1,206 12th-grade participants (196 career academy and 1,010 nonacademy students) were used in this study. These participants came from six high schools located in one large urban school district. Each of the…

This study compares two methods of defining groups for the detection of differential item functioning (DIF): (a) pairwise comparisons and (b) composite group comparisons. We aim to emphasize and empirically support the notion that the choice of pairwise versus composite group definitions in DIF is a reflection of how one defines fairness in DIF…

The percentage of students retaking college admissions tests is rising (Harmston & Crouse, 2016). Researchers and college admissions offices currently use a variety of methods for summarizing these multiple scores. Testing companies, interested in validity evidence like correlations with college first-year grade-point averages (FYGPA), often…

Some high schools are moving towards standards-based grading in an attempt to produce consistent grading practices; however, the change's impact on college readiness is not clear. The purpose of this study was to explore the effect of high school's grading practices as it relates to ACT scores and grade point averages (GPAs). Existing data were…

This study is an extension of two previous studies that provided profiles of persisting STEM majors overall (regardless of academic performance) and persisting STEM majors who earned semester GPAs of 3.0 or higher (Westrick, 2016, 2017). Using data from 25 four-year institutions, this study compared the mean ACT assessment scores, HSGPAs, and ACT…

Acid-base chemistry is central to a wide range of reactions. If students are able to understand how and why acid-base reactions occur, it should provide a basis for reasoning about a host of other reactions. Here, we report the development of a method to characterize student reasoning about acid-base reactions based on their description of…

College admission offices receive many different pieces of information on each applicant to their institution. The job of considering this information becomes further complicated when the information is not consistent across applicants. An example of one such complication is receiving SAT scores for some applicants and receiving ACT scores for…

Agricultural education is defined by a best practice three-component model of instruction that includes a classroom experience, leadership development and FFA involvement, and an experience-based activity through a Supervised Agricultural Experience program (SAE). Based on program of activities award criteria, each year state FFA associations…

In preparation for online administration of the ACT® test, ACT conducted studies to examine the comparability of scores between online and paper administrations, including a timing study in fall 2013, a mode comparability study in spring 2014, and a second mode comparability study in spring 2015. This report presents major findings from these…

There is an abundance of research associated with the belief that factors such as educational expenditures, socioeconomic demographics, geographic location, district size and school funding have a relationship to student achievement. This study provides insight into the relationship between these factors and the effect it has on student academic…

Comparing retention rates for 91 Black women and 56 Black men who participated in the African American Student Network with 68 women and 36 men who were randomly selected from the population of Black undergraduates at a Midwestern university, we included an analysis of covariance to control for ACT score and first-term grade point average. Results…

We examine the impact of a flipped classroom model of learning on student performance and satisfaction in a large undergraduate introductory statistics class. Two professors each taught a lecture-section and a flipped-class section. Using MANCOVA, a linear combination of final exam scores, average quiz scores, and course ratings was compared for…

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…
