The present study defined three levels of contextualized media and investigated their influences on students' science attitudes, comprehension, and argumentation. To achieve the purpose, an online game-based science argumentation (OGSA) program was developed for the experiments (N = 148). The OGSA included three versions for student argumentation…

This dissertation conducted a science classroom intervention using two instructional approaches, computational modeling and paper-based pictorial modeling, in the context of food webs. A series of research papers were written on the impact of the intervention on students' attitudes and learning, and on teachers via professional development and…

This study used a between-subjects experimental design to examine the effects of three different computer-based instructional strategies (concept map, refutation text, and expository scientific text) on science learning. Concept maps are node-link diagrams that show concepts as nodes and relationships among the concepts as labeled links.…

This study investigated the effectiveness of using Google Docs in collaborative concept mapping (CCM) by comparing it with a paper-and-pencil approach. A quasi-experimental study was conducted in a physics course. The control group drew concept maps using the paper-and-pencil method and face-to-face discussion, whereas the experimental group…

Current study aimed to examine the effects of web-based instructional material enriched by concept maps, the academic achievement of 7th graders in "Structure and Properties of Matter" unit. The study utilized a quasi-experimental model with pretest-posttest control group design. A sample of the study was composed of 58 students.…

The current study investigated whether learning from dynamic and two presentation formats for static visualizations can be enhanced by means of cueing. One hundred and fifty university students were randomly assigned to six conditions, resulting from a 2x3-design, with cueing (with/without) and type of visualization (dynamic, static-sequential,…

Man engages in the continuous construction of models to describe his reality. This assumption led to some instructional research at Oakland University, Rochester, Michigan, developing and testing a systems model for the classroom. A model building process labeled message storage and retrieval was developed in some detail. Using this retrieval…

Optimum time for efforts to attract minority students to a science career is when the students are enrolled in grade school and junior high school rather than at undergraduate and graduate levels, where many present programs are aimed. Student population is at its maximum in grade school, and successful efforts will reduce the amount of remedial…
