The study was carried out to determine the use of computer-based multimedia presentation on Senior Secondary School Students' Achievement in Agricultural Science. The study was a quasi-experimental, pre-test, post-test control group research design type, using intact classes. A sample of eighty (80) Senior Secondary School One (SS II) students was…

The authors mainly aimed to investigate the following question: Are there any significant effects of the first combined method of a conceptual change approach with refutation text, worksheets, and activities with respect to the second combined method of a conceptual change approach with conceptual texts, presentations, and activities on students'…

The study examined the effects of video-based multimedia instruction on secondary school students' achievement and retention in biology. In Nigeria, 120 students (60 boys and 60 girls) were randomly selected from four secondary schools assigned either into one of three experimental groups: Animation + Narration; Animation + On-screen Text;…

This paper examines the effect of a podcasting task on the examination performance of several hundred first-year chemistry undergraduate students. Educational researchers have established that a deep approach to learning that promotes active understanding of meaning can lead to better student outcomes, higher grades and superior retention of…

The aim of this study is to examine the impact of writing tasks on the 5th grade students' academic achievement and scientific attitude in science and technology course. The research is a quasi-experimental research including pre-test and post-test designs. These tests were administered as pre-test and post test to the groups. A total of sixty-two…

Our study capitalized on a unique natural experiment rather than a researcher-designed, randomized experiment whereby, thanks to the Australian Government's Digital Education Revolution, half of grade 9 students in 2008 received laptops and half did not. Consequently in late 2011, when these students sat for their grade 12 external examinations…

The authors investigated whether the amount of instructional guidance affects science learning and self-efficacy. Sixty 9- and 10-year-old children were randomly assigned to one of the following three instructional conditions: (a) guided instruction consisting of examples and student-generated explanations, (b) direct instruction consisting of a…

The purpose of this study was to explore whether Modeling Instruction, compared to traditional lecturing, is an effective instructional method to promote academic achievement in selected high school physics classes at a rural middle Tennessee high school. This study used an "ex post facto," quasi-experimental research methodology. The…

The effects of student-directed activity-based learning (SDABL) were examined in two high school chemistry classes. Students in the SDABL class were given pretest results, a list of standards to be mastered, and a chart of learning activities categorized by difficulty level. They selected activities to meet their needs and preferences.…

The aim of the study was to explore the effects of cooperative learning on General Science achievement among 9th class students. Based upon previous research literature it was hypothesized that significant difference existed between the mean posttest scores of General Science achievement of experimental group and control group. The pretest…
