Many studies have characterized students' difficulties in understanding and reasoning about scientific mechanisms. Some of those studies have drawn implications on teaching mechanisms and how to guide students while reasoning mechanistically. In this theoretical article, I claim that one component that has not garnered much attention in the…

Recent research and policy documents call for engaging students and teachers in scientific practices such that the goal of science education shifts from students "knowing" scientific and epistemic ideas, to students "developing and using" these understandings as tools to make sense of the world. This perspective pushes students…

Reform based curriculum offer a promising avenue to support greater student achievement in science. Yet teachers frequently adapt innovative curriculum when they use them in their own classrooms. In this study, we examine how 19 teachers adapted an inquiry-oriented middle school science curriculum. Specifically, we investigate how teachers'…

Epistemic criteria are the standards used to evaluate scientific products (e.g., models, evidence, arguments). In this study, we analyzed epistemic criteria for good models generated by 324 middle-school students. After evaluating a range of scientific models, but before extensive instruction or experience with model-based reasoning practices,…

In this study we investigate students' learning during their interaction with two exhibits at a science center. Specifically, we analyze both students' procedures when interacting with exhibits and their understanding of the scientific concepts presented therein. Bernstein's theory of pedagogic discourse (1990, 2000) provided the sociological…

This research used semistructured interviews to investigate students' (n=32) understanding of electrochemistry following a 7-9 week course of instruction. Three misconceptions were identified and incorporated with five previously reported into an alternative framework about electric current involving drifting electrons. Also noted was the tendency…

This male-specific study examined the development of integrated process skill in the context of open-inquiry laboratory sessions. Findings from this qualitative study indicate that male students develop higher-order process skills through nontraditional laboratory experiences that provided the students with freedom to perform experiments of…

Examines the educational value of exhibits for transferring wildlife information to high school students. Reports that the passive exhibitry technique produced increases in the wildlife knowledge of students. (Author/YP)

Reports a study of replacing a basal reading program with a curriculum emphasizing science activities, science process skills, and science-content-based reading in three fourth-grade classrooms (n=51). Results showed these students displayed significantly greater sores on tests of reading and science, and more positive attitudes toward science and…

Tests in each science area were developed around six laboratory tasks. Students had to plan an investigation, collect and organize data, and formulate conclusions based on calculations and graphs. Over 1,000 students from 32 Ohio schools formed the sample for this study. Data are presented by skill and by task. An analysis for gender and school…

The study explores urban second graders' thinking and talking about the concepts of evaporation, boiling, and condensation that emerged in the context of intertextuality within an integrated science-literacy unit on the topic of States of Matter, which emphasized the water cycle. In that unit, children and teacher engaged in a variety of…

From an analysis of 14 secondary student's actions and thought processes, it was found that technology's level of information affected the focus of student observations. The microcomputer group focused primarily on the graph while other groups exhibited multiple foci. The discussion data also reveal that students have three main ideas about how…

Study examined the influence of an intensive chemical demonstration workshop on fostering pedagogical content knowledge growth among science teachers identified as novice chemical demonstrators (n=8). The two-week workshop was designed around four training elements considered important for effective teacher inservicing: theory, modeling, practice,…

Discusses the use of analogies and other instructional strategies (problem solving, demonstration, group labs, and large group discussion) in dealing with students' preconceptions in physics. (PR)
