Teacher professional development (PD) is essential to continuously improve teaching skills, to adapt to diverse student needs, and to promote equity and inclusion. Only a few studies to date have synthesized how PD programs improve teachers' content knowledge and instructional quality, as well as students' academic performance. In this…

Through the lens of science capital, this research aims to detect the key factors and their main effects in identifying students with science-related career expectations. A machine learning approach (i.e., random forest) was employed to analyze a dataset of 519,334 15-year-old students from the Programme for International Student Assessment (PISA)…

Previous research has demonstrated the potential of examining log-file data from computer-based assessments to understand student interactions with complex inquiry tasks. Rather than solely providing information about what has been achieved or the accuracy of student responses ("product data"), students' log files offer additional…

Science education reform efforts in the Unites States call for a dramatic shift in the way students are expected to engage with scientific concepts, core ideas, and practices in the classroom. This new vision of science learning demands a more complex conceptual understanding of student engagement and research models that capture both the…

In this article, we report on the results of a study comparing the preparedness, content knowledge, and instructional practices of elementary science specialist (ESS) teachers with those of a matched sample of self-contained elementary teachers. Analysis of survey data collected for the two groups indicated that ESS teachers were more likely than…

This study investigated exam achievement and affective characteristics of students in general chemistry in a fully-randomized experimental design, contrasting Peer-Led Team Learning (PLTL) participation with a control group balanced for time-on-task and study activity. This study population included two independent first-semester courses with…

Data from 60 observations of 10 teachers and 10 each of their students showed that type/quality of teaching strategy predicted 37 percent of variance in engagement and that the more indirect the teaching strategy, the greater the students' involvement in learning tasks. Implications of these and other findings are discussed. (Author/JN)

Examined management behaviors of junior high science teachers (N=16) and the relationship to task involvement of students operating in small group laboratory settings. Results of 91 observations indicate that teacher behavior was directed in three ways: whole class, small groups, and nonclass related. Implications for science instruction are…

Investigated classroom management practices in 26 classes taught by 13 junior high and middle/junior high school teachers using student-on-task, off-task, and disruptive student behaviors as primary criteria of management effectiveness. Effective management practices for general classroom procedures, laboratory procedures, managing student…

Results of modifying mastery learning strategy to two diagnostic cycles with high school chemistry students (N=156) indicated that achievement of mastery learning students was significantly greater than that on nonmastery learning students. Attitudes toward science/science instruction were not significantly different but were positive in both…

Investigated relationships between physics achievement and language of instruction where instruction was in the second language of both students and teachers. Grade 10 subjects (N=176) studied light/sound in either Chinese (N=90) or English (N=86). No differences in achievement, students' motivation, and time spent in physics were found.…

Investigated relationships among college students (N=76) science achievement, engaged time (observed and perceived), personal characteristics of academic aptitude, reasoning ability, attitude toward science, and locus of control. Among the results reported are significant relationships between engaged time measures and achievement, and between…

Determined relationships among teacher classroom management behavior, student engagement (N=269), academic achievement (N=570), and academic aptitude (N=649). Twelve indicators from Georgia Teachers Performance Assessment Indicators were used to measure teacher classroom management behaviors. Results, obtained during 2-week units taught by 30…

Examined relationships between teaching behaviors and student engagement in 13 middle school science classes. Results indicated that seven managerial variables and four instructional variables were significantly related to student engagement rates. Types of tasks allocated by teachers were also significantly related to types of tasks undertaken by…

Investigated if relationships existed between middle school students (N=105) science concept structure interrelatedness competence and their time on task, science achievement, scholastic aptitude, previous experience with concept structure interrelatedness, attitudes toward science, interest in science, science curiosity, and self-concept of…
