Trends in International Mathematics and Science Study (TIMSS) is an international comparative study that has been implemented by the International Association for the Evaluation of Educational Achievement (IEA) since 1995. This proposed study is aimed to identify the correlations of science classroom teachings with eighth graders' science…

Randomised controlled trials (RCTs) can be at risk of bias. Using data from a RCT, we considered the impact of post-randomisation bias. We compared the trial primary outcome, which was administered blindly, with the secondary outcome, which was not administered blindly. From 44 schools, 522 children were randomised to receive a one-to-one maths…

This study examines the existing knowledge that pre-service elementary teachers (PSETs) have regarding heat energy, heat transfer and insulation. The PSETs' knowledge of heat energy was initially assessed by using an activity: determining which container would be best to keep hot water warm for the longest period of time. Results showed that PSETs…

The work from the University of Central Florida's STEM summer camp (sponsored by Workforce Central Florida) is shared. The camps targeted low-SES schools with a high percentage of students on free and reduced lunch as well as high percentages of students with. Students were given preassessments and postassessments to gauge their knowledge of and…

The article argues that science assessment should change from an item-driven to a construct-driven practice and pay more attention to disciplinary scientific reasoning. It investigates assessment scales developed from a novel theoretical rationale, describing scientific reasoning as three fundamental practices (hypothesizing, experimenting, and…

The lack of exposure to practical work in primary schools leads to incompetency in manipulative skills and students may carry this problem with them to secondary school. To address this issues, an in-depth qualitative study was conducted during transition from primary to secondary school. The research involved 10 primary school students (grade 6)…
