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…

Background: Science teachers represent the critical link to the development of a scientifically literate citizenry who is capable of addressing societal problems and global challenges in ways that positively affect the quality of life. Purpose: We investigated how a long-term, inquiry-based professional development program could be utilized to…

Ocean currents play an important role in regulating the Earth's climate by redistributing ocean heat around the planet. One important climate phenomenon that includes several large ocean currents is the Atlantic Meridional Overturning Circulation, which is the process of warm surface currents in the North Atlantic Ocean moving to the Arctic to…

The National Assessment of Educational Progress (NAEP) measures student science achievement nationally, state by state, and, most recently, across selected urban school districts. Periodically, the framework underlying the science assessment is revised or updated. This document, "Science Framework for the 2019 National Assessment of…

This article proposes an evidence-based and engaging approach to teaching the mechanisms driving the movement of tectonic plates that should lead high school students towards the prevalent theories used in peer-reviewed science journals and taught in universities. The methods presented replace the inaccurate and outdated focus on mantle convection…

This study offers curriculum developers, teachers, and science education researchers a fine-grained profile on strengths and weaknesses in specific science domains and topics. The study involved a representative sample of 3844 Norwegian pupils in grade 8. Their responses on 216 TIMSS items in 18 topics from 4 science domains were modelled in a…

Using three constructs taken from Latour's 2005 book, "Reassembling the Social," we consider our work in 2 contexts that were part of a project to support science teachers working with English learners: an 8th-grade physical science class in a summer science enrichment academy, and a 6th-grade Earth science class in a public middle…

Glaciers and ice ages are important topics in teaching geomorphology, earth history, and climate change. As with many geoscience topics, glacier formation, glacier movement, glacial morphology, and ice ages consist of a wide variety of processes and phenomena. Accordingly, it must be decided which of those processes and phenomena should be part of…

The present dissertation in practice (DiP) proposal delineates an action research study designed to evaluate the use of problem-based learning (PBL) in an eighth-grade earth science class to assess the impact of PBL on student achievement. I have observed that students often struggle with developing an understanding of how the motions of the sun,…

Plate tectonics is the organizing paradigm of geosciences, but it is also conceptually complex, and students often struggle with developing a system level understanding of the earth. This article reports on research designed to create a characterization of the different levels of sophistication around plate tectonics in the form of a learning…

A longstanding aim of education efforts to position students as knowledge constructors so they are engaged in the building and shaping their learning environment. Current education reforms situate student sense making around authentic science inquiries where students are engaged in the practices of science. In the science classroom, this means…

This is an abridged version of the "Science Framework for the 2015 National Assessment of Educational Progress." The National Assessment of Educational Progress (NAEP) and its reports are a key measure in informing the nation on how well the goal of scientific literacy for all students is being met. The framework reflects the nature and…

This study aims to better understand questions related to the impact of teacher quality and access to qualified teachers in China. A large-scale data set collected in 2010 in China was used along with concurrently collected teacher questionnaires. In total, surveys from 9,943 8th grade students from 343 middle schools in 6 provinces were used,…

Using data from the 2011 (Chinese) Student Academic Achievement Evaluation, we examined whether within-school socioeconomic gaps in science achievement exist across science subjects, how consistent they are, and whether there are relationships between school average science achievement and within-school socioeconomic gaps in science achievement.…

Mary Colson is an eighth-grade Earth science teacher at Horizon Middle School, and Russ Colson is a professor of geology and Earth science education in the Department of Anthropology and Earth Science at Minnesota State University Moorhead, both in Moorhead, Minnesota. Since her first year in teaching eighth grade Earth science, in 1986,…
