Undergraduate students have different attitudes toward the geosciences, but few studies have investigated these attitudes using Q methodology. Q methodology allows the researcher to identify more detailed reasons for students' attitudes toward geology than Likert methodology. Thus this study used Q methodology to investigate the attitudes that 15…

This paper describes HASbot, an automated text scoring and real-time feedback system designed to support student revision of scientific arguments. Students submit open-ended text responses to explain how their data support claims and how the limitations of their data affect the uncertainty of their explanations. HASbot automatically scores these…

This study examines how middle school students develop an increasingly coherent understanding of aquatic ecosystems. As part of a broader design research study that used Structure-Behavior-Function (SBF) theory as an organizing conceptual representation, we created two instructional units that focused on pond and aquarium environments. We coded…

This article presents an empirical analysis of conceptual difficulties encountered and ways students made progress in learning at both individual and group levels in a classroom environment in which the students used an embodied modeling activity to make sense of a specific scientific scenario. The theoretical framework, coordination class theory,…

Evaluation is an important aspect of science and is receiving increasing attention in science education. The present study investigated (1) changes to plausibility judgments and knowledge as a result of a series of instructional scaffolds, called model-evidence link activities, that facilitated evaluation of scientific and alternative models in…

Understanding the features of science learning experiences that organize and motivate children at early ages can help educators and researchers find ways to ignite interest to support future passion and learning in the sciences at a time when children's motivation is declining. Using a sample of 252 fifth-and sixth-grade students, we…

Framed in theories of social semiotics, this multiple case study describes and categorizes the actional-operational modes used by three middle school earth science teachers throughout the course of one school year. Data included fieldnotes, photographs, and video recordings of classroom instructions as well as periodic interviews with the…

Teachers' use of inquiry has been studied largely without regard for the disciplines in which teachers practice. As a result, there is no theoretical understanding of the possible role of discipline in shaping teachers' conceptions and enactment of inquiry. In this mixed-methods study, conceptions and enactment of inquiry for 60 National Board…

We use a construct-based assessment approach to measure learning progression of energy concepts across physical, life, and earth science contexts in middle school grades. We model the knowledge integration construct in six levels in terms of the numbers of ideas and links used in student-generated explanations. For this study, we selected 10 items…

The cause of the seasons is often associated with a very particular alternative conception: That the earth's orbit around the sun is highly elongated, and the differences in distance result in variations in temperature. It has been suggested that the standard diagrams used to depict the earth's orbit may be in some way responsible for the initial…

Implementation of science curriculum materials has been a fundamental challenge in science education for decades. Policy researchers have argued that alignment of standards, curriculum, and assessment are the key to supporting implementation. This paper focuses on teachers' perceptions of curricular alignment and on curriculum implementation using…

The goal of this case study was to describe characteristic features of abductive inquiry learning activities in the domain of earth science. Participants were undergraduate junior and senior students who were enrolled in an earth science education course offered for preservice secondary science teachers at a university in Korea. The undergraduate…

Earth Systems Science (ESS) is emerging rapidly as a discipline and is being used to replace the older earth science education that has been taught as unrelated disciplines--geology, meteorology, astronomy, and oceanography. ESS is complex and is based on the idea that the earth can be understood as a set of interacting natural and social systems.…

Reviews the Crustal Evolution Project (CEEP) for the development and evaluation of geology materials to supplement existing science curricula. (SL)
