Classrooms with higher teaching quality were associated with higher learning outcomes in mathematics and science. Classrooms where teachers reported high degrees of limitations to teaching in the classroom--including disruptive students or students with language barriers--were associated with lower learning outcomes. These are two of the important…

Executive function (EF) predicts children's academic achievement; however, less is known about the relation between EF and the actual learning process. Furthermore, more research is needed to better understand how different aspects of the learning environment interact with EF to influence learning. The current dissertation includes two studies to…

Science students' study success rates in the first year of higher education (FYHE) are problematic. Although a considerable amount of previous research has been carried out to investigate the determinants of students' academic achievement in FYHE, there has been little discussion about the incremental value of non-cognitive factors over and above…

This study is one of the first to estimate the impact of "inclusive" science, technology, engineering, and mathematics (STEM) high schools using student-level data. We use multiple statistical strategies to estimate the effect on student achievement from 2 years of attendance at six such high schools in Ohio. The results indicate that…

Problem solving is a highly valued skill in chemistry. Courses within this discipline place a substantial emphasis on problem-solving performance and tend to weigh such performance heavily in assessments of learning. Researchers have dedicated considerable effort investigating individual factors that influence problem-solving performance. The…

Addressed is the current practice in educational reform of reducing time for science instruction in favor of traditional reading/language arts instruction. In contrast, presented is an evidence-based rationale for increasing instructional time for K-5 science instruction as an educational reform initiative. Overviewed are consensus…

This study developed two testing devices, namely the animation-based test (ABT) and the graphic-based test (GBT) in the area of earth sciences covering four domains that ranged from astronomy, meteorology, oceanography to geology. Both the students' achievements of and their attitudes toward ABT compared to GBT were investigated. The purposes of…

The purpose of this study was to compare the academic performance of students enrolled in coeducational instruction and single-gender instruction. Within this framework, the researcher examined class type, gender, and racial/ethnicity using the sixth grade CRCT scores of selected students in the areas of mathematics and science. The fifth-grade…

Among 238 Canadian high school seniors who took a science achievement test, 15 were interviewed afterward. Girls scored lower than boys and more frequently cited school experiences (rather than informal experiences or common knowledge) as the basis for answers. Some items elicited spontaneous negative reactions from girls but not boys. Contains 55…

Evidence from the research literature suggests that a variety of cognitive factors are responsible for chemistry achievement. This investigation examined the role that four cognitive factors, namely, prior knowledge, formal reasoning ability, memory capacity and field independence/dependence, play on achievement in chemistry as measured by tests…
