The purpose of this study was to explore the effect of visually assisted guided discovery learning strategy on grade 10 students' problem solving skills of learning plane geometry in Woldia City, North Wollo, and Ethiopia. A nonequivalent quasi-experimental pretest-posttest-control group design and a case study design were used. The population of…

In partnership with both formal and informal learning institutions, researchers have been building a suite of online games, called choicelets, to serve as interactive assessments of learning skills, e.g. critical thinking or seeking feedback. Unlike more traditional assessments, which take a retrospective, knowledge-based view of learning,…

This study investigated the effectiveness of a unit plan designed to enhance students' three-dimensional geometry and spatial ability skills. Research participants consisted of 50 students, 19 males and 31 females, and two teachers from a public high school in a suburban middle-class community. The students in this study were 9th and 10th graders…
