Developing understanding of models and proficiency with modeling practice is challenging for both teachers and students. This 2-year study first investigated existing instructional strategies employed by teachers while teaching Earth and Space Science with dynamic physical models. Summer professional development introduced a conceptual framework,…

Although the practice of giving examples is central to the effective teaching and learning of science, it has been the object of little educational research. The present study attends to this issue by systematically examining the exemplification practices of a university professor and his students' learning experiences during a biology lecture on…

Understanding how geologists conduct fieldwork through analysis of problem solving has significant potential impact on field instruction methods within geology and other science fields. Recent work has highlighted many aspects of fieldwork, but the problem solving behaviors displayed by geologists during fieldwork and the associated cognitive…

Many students feel the curriculum is detached from their lives and interests. Indeed, about half the questions asked by high school biology students are not addressed by the curriculum. This study presents a strategy to incorporate students' curiosity questions into the curriculum as a way to reduce the disparity between students' interests and…

We describe efforts toward the development of a hypothetical learning progression (HLP) for the growth of grade 7-14 students' models of the structure, behavior and properties of matter, as it relates to nanoscale science and engineering (NSE). This multi-dimensional HLP, based on empirical research and standards documents, describes how students…

This study focuses on a professional development program for science teachers near or on American Indian reservations in Montana. This program was framed by culturally relevant pedagogy premises and was characterized by instructional strategies and content foci resulting from the intersection between three cultures: tribal, science teaching, and…

Teachers play a central role in inquiry science classrooms. In this study, we investigate how seven teacher variables (i.e., gender, experience, perceived importance of inquiry and traditional teaching, workshop attendance, partner teacher, use of technology) affect student knowledge integration understanding of science topics drawing on previous…

The purpose of this pragmatic action research study was to explore our re-conceptualization efforts in preparing pre-service teachers to guide the inquiry process with formative assessment and subsequently use the understandings to improve our teacher preparation program. The process was guided by two questions: to what extent did course…

This study investigated the development in students' nature of science (NOS) views in the context of an explicit inquiry-oriented instructional approach. Participants were 18 seventh-grade students who were taught by a teacher with "appropriate" knowledge about NOS. The intervention spanned about 3 months. During this time, students were engaged…

The purpose of this study was to investigate the possible responses to anomalous data obtained from experiments that are repeatable by carrying out additional or alternative experiments in the laboratory. Based on an analysis of responses from scientists to anomalous data taken from identification experiments on the Vinland Map, it was assumed…

Explores why students fail to learn from teacher demonstrations in a physics course. Reports that six dimensions may have prevented student learning, including lack of a theoretical framework to separate signals from noise, interference of discourses learned in other contexts, interference from other demonstrations and images, and problems in…

This study assessed the influence of a 3-year professional development program on elementary teachers' views of nature of science (NOS), instructional practice to promote students' appropriate NOS views, and the influence of participants' instruction on elementary student NOS views. Using the VNOS-B and associated interviews the researchers…

This article investigates three teachers' conceptions and use of inquiry-based instructional strategies throughout a professional development program. The professional development program consisted of a 2-week summer inquiry institute and research experience in university scientists' laboratories, as well as three academic year workshops. Insights…

Presents a case study of an experienced high school chemistry teacher. Examines the teacher's conceptions about teaching science and compares them with the observed patterns of practice. Highlights the complexity of characterizing a teacher's thinking and its relationship to actions. Discusses the value of the insight researchers gain from sharing…

Investigates how computers and modeling software contributed to students' interactions and learning in a physics course. Results indicate that while computer environments have some potential as learning tools, they also limit interactions in significant ways, rendering them less than ideal for everyday classroom use. Contains 60 references.…
