With an educational issue that has caught the attention of many countries in the world (study load), a population of 8th graders from a typical Chinese metropolitan city (40,536 from 118 schools), and an advanced statistical strategy (multilevel piecewise regression), we examined whether there was a turning point in terms of the effects of study…

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…

This paper discusses the nature of learner engagement with science content during small group discussions in which learners use their home languages. We observed that learners reverted to their home languages in small group discussions, yet very little is known about the dynamics of learner engagement when they use their home languages in…

The major purpose of this study was to determine the questioning patterns of teachers in science classes. The design employed for the study was a case study. To guide this study, five research questions were asked and answered. The samples of the study consisted of 20 senior secondary schools and 60 science teachers. The instruments used for data…

This report outlines a 2-year investigation into how secondary science teachers used professional development (PD) to build scientific classroom discourse communities (SCDCs). Observation data, teacher, student, and school demographic information were used to build a hierarchical linear model. The length of time that teachers received PD was the…

As twenty-first century skills become a greater focus in K-12 education, an infusion of technology that meets the needs of today's students is paramount. This study looks at the design and creation of a Multiplayer Educational Gaming Application (MEGA) for high school biology students. The quasi-experimental, qualitative design assessed the…

In line with the cognitive theory of multimedia learning by Moreno and Mayer (2007), an interactive, multimodal learning environment was designed for the pretraining of science concepts in the joint area of physics, chemistry, biology, applied mathematics, and computer sciences. In the experimental set up, a pretest was embedded in order to…

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…

The purpose of this study was to determine if a high school graduation examination influences instructional practices. Data were obtained from a survey instrument given to a stratified random sample of Tennessee science teachers who teach the content that is tested on their state's high school graduation examination. An analysis showed teachers…

Validity of using time and behavior as predictors of learning was tested by collecting detailed visitor behavior and time expenditure while interacting with a participatory museum exhibit. Data from 12- and 13-year-olds (N=63: 32 males, 31 females) support the feasibility of using these predictors. Learning was measured using a 14-item test.…

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.…

Student involvement in 24 science classes (grades 8, 9, 10) during instruction involving teacher exposition, exposition with prop, and demonstration was videotaped. Findings indicated that only nine teachers used class demonstrations and that the increased levels of pupil attention and task involvement increased during demonstration lesson…

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…
