This study reports the impacts of the Scientific Concept Construction and Reconstruction (SCCR) digital learning system on eighth grade students’ concept construction, conceptual change, and scientific reasoning involving the topic of “atoms”. A two-factorial experimental design was carried out to investigate the effects of the approach of instruction and students’ level of scientific reasoning...

The purpose of this study was to compare the effectiveness of two kinds of reinforcements, tangible reinforcements and social reinforcements, on the academic achievement of eighth-grade female students with intellectual disabilities in the science subject. The study was an experimental method by pretest, with a control group. The participants of the study comprised 45 female students with intel...

This study assessed whether five hypothesized requirements for goal achievement predicted participants' success or failure in achieving a goal. Amazon Mechanical Turk users (n=182) were randomly assigned either to identify a recent goal they had accomplished or failed to accomplish. These hypothesized requirements were derived from prior research and include sufficient social support, time avai...

Building standards recommend maximum background noise levels (BNL) and reverberation times (RT) for unoccupied classrooms. However, existing research does not show a consistent correlation between these parameters and student achievement. Through in situ testing, this research seeks to determine what acoustical conditions should be attained in elementary schools for students to meet educational...

This paper is a report of the impact of an externally funded, multiyear systemic reform project on students’ science achievement on a modified version of the Third International Mathematics and Science Study (TIMSS) test in 33 small, rural school districts in two Midwest states. The systemic reform effort utilized a cascading leadership strategy of professional development delivered at summer w...

PURPOSE This study was performed to identify academic and nonacademic predictors of the success of entrants to Chungbuk National University Graduate Medical School (CNUMS) during the first 3 years of completion. METHODS We analyzed the academic achievements in preclinical education in the first 2 years in students who were admitted in 2005 and 2006 and compared them with cognitive admission v...

PURPOSE To examine the impact of integrating physical activity with elementary curricula on fluid intelligence and academic achievement. METHODS A random sample of 3rd grade teachers integrated physical activity into their core curricula approximately 30 minutes a day, 3 days a week from January 2008 to April 2008. Noninvasive fluid intelligence cognitive measures were used along with State-m...

Objective: To investigate the 3-year course of learning disorders (LDs) and academic achievement in a sample of students with psychiatric disorders who were newly classified by the special education category of behavioral disorder (BD). Method: The occurrence of four definitions for LD (both discrepancy and low achievement) based on the WISC-R and the Woodcock-Johnson Psychoeducational Battery ...

PURPOSE This study was conducted to determine the effect of physical education class enrollment and physical activity on academic achievement in middle school children. METHODS Participants were 214 sixth-grade students randomly assigned to physical education during either first or second semesters. Moderate and vigorous physical activity (MVPA) (number of 30-min time blocks) outside of schoo...
