Abstract
The purpose of this dissertation was to determine the effects of gender, SES, race, and change over time on academic performance as measured by ACT Aspire Summative Science Assessment scores. Scores chosen for this study were from the 2018-2019 10thgrade students in a Northwest Arkansas school district and these same students’ scores from their 7th-grade year in 2015-2016 to determine if change over time existed. The samples for this study were chosen from one Northwest Arkansas school district. ACT Aspire Summative Science Assessment scores were used to provide the academic performance data for the dependent variable used in each hypothesis. During the Spring 2019, the ACT Aspire Summative Science Assessment was administered to 10th-grade students across Arkansas, including students from the selected district. For Hypothesis 1, a significant interaction effect between gender and time existed. Males and females, on average, significantly increased their scores from Time 1 (Grade 7) to Time 2 (Grade 10), with females displaying a larger, significant increase. The effect size was interpreted as small. For Hypothesis 2, the main effect for SES was significant, with the not eligible for free or reduced lunches group significantly outscoring the eligible group, with a large effect size. Also, the main effect for time was significant, with both groups combined increasing from Time 1 (Grade 7) to Time 2 (Grade 10). The effect size was also large. For Hypothesis 3, a statistically significant interaction effect existed between race and time. White and non-White students, on average, significantly increased their scores from Time 1 (Grade 7) to Time 2 (Grade 10), with the White students displaying a larger, significant increase. The effect size was interpreted as medium.
