This research with middle school students from Kentucky (KY) and Nevada (NV) provides a snapshot of students' spatial-scientific understandings as we explored how well students understand lunar-related content, both spatially and scientifically, after receiving instruction with similar curricular Earth-Space content. Utilizing a lens of spatial…

Science teacher educators use examples of practice to support teacher candidates (TCs) learning to engage in new forms of science teaching. However, interpretation of these examples assumes a level of expertise about practice TCs lack. This article describes a study designed to determine some of the differences between expert teachers' and TCs'…

Through the GK-12 program of the National Science Foundation, graduate student fellows in a coastal marine and wetland studies program were trained to present targeted science concepts to middle- and high-school classes through their own research-based lessons. Initially, they were taught to follow the 5-E learning cycle in lesson plan…

The purpose of the study was to assess elementary students' science process skills, content knowledge, and concept knowledge after one year of participation in an elementary Science, Technology, Engineering, and Mathematics (STEM) program. This study documented the effects of the combination of intensive professional development and the use of…

This quasi-experimental study investigated how explicit instruction about multiple modes of representation (MMR) impacted grades 7 (n = 61) and 8 (n = 141) students' learning and multimodal use on end-of-unit assessments. Half of each teacher's (n = 3) students received an intervention consisting of explicit instruction on MMR in science…

The purpose of the present quasi-experimental study was to examine the impact of a horseshoe crab citizen science program on student achievement and science, technology, engineering, and mathematics (STEM) career motivation with 86 (n = 86) eighth-grade students. The treatment group conducted fieldwork with naturalists and collected data for a…

This study examined the role of gender in the areas of environmental education that included environmental knowledge, attitudes, behaviors, and comfort levels in the outdoors. The current study was part of a larger study designed to explore the effects of a treatment that consisted of 14 weeks of outdoor lessons conducted in the schoolyard as…

Proposes methods by which laboratory practical exams may be structured to assess outcomes from laboratory instruction. Presents eight general considerations for writing and using practical exams. Describes four example laboratory exams involving a box camera, circuit boxes, floating objects, and light. (MDH)

Discusses Vee mapping, a technique to assist students in categorizing the relationship between the conceptual and procedural aspects of science. Presents a study to investigate elementary education majors' (n=27) use of the Vee heuristic and concept mapping for the construction of knowledge; attitudes toward learning science in collaborative…

Describes three perspectives from which middle school teachers can plan laboratory activities for the purpose of improving students' scientific literacy. Perspectives are the learning cycle approach categorizing activities by stages of development; problem-solving skills approach categorizing activities according to the amount of teacher control;…
