This article reports the results of a randomized control trial of a semester-long intervention designed to promote ninth-grade science students' use of text-based investigation to create explanatory models of biological phenomena. The main research question was whether the student participants in the intervention outperformed the students in the…

It is now widely accepted, and indeed emphasized in the Next Generation Science Standards, that science education should encompass scientific practice as well as science content. By participating in an intellectual community engaged in the broad range of activities that constitute scientific inquiry, rather than simply mastering isolated science…

The purpose of the study was to investigate the effectiveness of case-based learning instruction over traditionally designed chemistry instruction on eleventh grade students' epistemological beliefs and their attitudes toward chemistry as a school subject. The subjects of this study consisted of 63 eleventh grade students from two intact classes…

This dissertation incorporates three studies that examine how the design of inquiry based science instruction, dynamic visualizations, and guidance for experimentation contribute to physics students' understanding of science. I designed a week-long, technology-enhanced inquiry module on car collisions that logs students' interactions with a…

This study was designed to compare the effectiveness of using traditional and integrated instructional strategies to increase student understanding of the core concepts of energy. There are mixed messages in the literature as to the success of using an integrated approach to teach science content, despite suggestions its use improves student…

Numerous investigations show that most school science teaching, in Spain and elsewhere, implicitly transmits an inductivist and very stereotyped view of science and conveys an unrealistic image of scientific work. We present some results of an investigation with fourth-level Spanish secondary education students (15 year olds) who were taught…

In this study, the effect of problem-based learning on students' academic achievement and performance skills in a unit on the human excretory system was investigated. Sixty-one 10th grade students, from two full classes instructed by the same biology teacher, were involved in the study. Classes were randomly assigned as either the experimental or…

This research project consists of a randomized experiment in St. Petersburg Catholic Schools. The question being addressed by the research is whether "Scott Foresman Science" is as effective as the current curricula being used in the participating campuses of the Roman Catholic Diocese of St. Petersburg. The research focuses on 3rd, 4th,…

This research project consists of a randomized experiment in Visalia Unified School District. The question being addressed by the research is whether "Scott Foresman Science" is as effective as or more effective than the curriculum being used at each site. Since Scott Foresman Science provides a significant reading component, the authors…

This research project consists of a randomized experiment in Ogden City School District. The primary purpose of this research is to produce scientifically based evidence of the comparative effectiveness of the "Scott Foresman" program. The question being addressed by the research is whether the "Scott Foresman" program is more…

Pearson Education contracted with Empirical Education Inc. to conduct five randomized experiments to determine the effectiveness of its "Scott Foresman Science" ("SFScience") curriculum and associated materials. This report addresses the experiment in Federal Way Public Schools in Washington State. The primary purpose of this…

In this paper, the authors' investigated whether "Scott Foresman Science" program, a year-long curriculum intended for daily use that provides a sequence of structured and supportive inquiry activities and text materials to develop students' independent investigative skills, is more effective than current science programs in five diverse…
