In this study, we examined the ways in which two middle school science teachers elicited and were responsive to students' initial science ideas for explaining an anchoring phenomenon while teaching the same model-based learning unit focused on plate tectonics. Data sources included student models, classroom video, and classroom artifacts. Our…

We investigate an interactive teacher-generated drawing strategy in which the teacher constructs a drawing with the help of the students. The students contribute their ideas on how to visualize to-be-drawn concepts, embedded in an interactive process. The present study explored whether learning from a scientific text on plate tectonics could be…

Guiding teachers to customize curriculum has shown to improve science instruction when guided effectively. We explore how teachers use student data to customize a web-based science unit on plate tectonics. We study the implications for teacher learning along with the impact on student self-directed learning. During a professional development…

Understanding mechanisms underpinning formation of convection currents is pivotal for developing explanations of plate tectonics when teaching Geoscience topics. While student generated diagrams explaining convection currents may be used to evaluate student conceptual understanding and alternative conceptions in this topic, students may need…

This study examined a case of GeoMapApp-based assessment to investigate a learning progression for middle school students' understanding of geoscience content and geocognition (spatial, temporal, and retrospective reasoning and system thinking). A 2-year GeoMapApp-based assessment process was administered along with a double-round of the construct…

This paper studies Greek junior high school students' alternative ideas, both initial and synthetic, on geodynamic phenomena. It comments in detail on students' concepts on Earth structure, earthquake occurrence, volcano formation, and relief change. Additionally, it attempts to trace and interpret how and why these ideas form (concept…

Understanding plate tectonics is pivotal to development of an integrated understanding of Geoscience topics. However, geology is frequently introduced to students in lower secondary school by describing separate processes, such as sedimentary rock formation, rather than investigating the overall driving forces for change. This study investigated…
