This study evaluated the level of change in students' knowledge of and attitudes toward healthy lifestyle behaviors and prevention of cardiovascular disease (CVD) following implementation of a Cardiovascular Disease Prevention Module in Grade 5 science classes. Two classes of students (n[subscript 1] = 39) were identified as the intervention group…

The purpose of this article is to address a major gap in the instructional sensitivity literature on how to develop instructionally sensitive assessments. We propose an approach to developing and evaluating instructionally sensitive assessments in science and test this approach with one elementary life-science module. The assessment we developed…

Student perceptions of classroom environment can provide useful criteria for evaluating educational alternatives. The My Class Inventory (MCI) was used with 588 3rd- to 5th-grade students in Texas in evaluating the effectiveness of instruction using a textbook, science kits, or a combination of both. Various analyses attested to the factorial…

This study addresses preservice teachers' perceptions toward online experiences, specifically, their perceptions about utilizing an online science methods curriculum versus a traditional methods curriculum. Thirty-eight senior level preservice teachers at a midwestern U.S. university completed surveys about their experiences during their methods…

We report on an evaluation of the effectiveness of Project ARIES, an astronomy-based physical science curriculum for upper elementary and middle school children. ARIES students use innovative, simple, and affordable apparatus to carry out a wide range of indoor and outdoor hands-on, discovery-based activities. Student journals and comprehensive…

The science achievement of 226 5th graders from districts that have a kit-based inquiry science curriculum supported by intensive professional development (PD) is compared with data from a group of 173 5th graders from other districts that use nonkit science materials and do not have systematic science PD for teachers. Within the kit-based…
