Since the release of "A Framework for K-12 Science Education" in 2012, there has been a significant shift toward the use of science and engineering practices that mirror the way scientists do their work (NRC 2012). The "Framework" states, "A focus on practices (in the plural) avoids the mistaken impression that there is…

This case study presents the analysis of teacher-student interaction in physics classrooms. The participants of the study were three physics teachers and 131 students from three upper primary schools (Grades 7 and 8) of Ethiopia. Data for the study were collected through observation of eight video recorded physics lessons. The analysis of videos…

Background: Researchers have indicated that assessment practices and methods should support learners' construction of meaningful understanding of knowledge. Understanding students' conceptions of assessment will enable us to construct more realistic, valid and fair assessments. Learners' conceptualization of assessment would be imperative to serve…

In this study, we investigated the value of a concept map marking guide as an alternative formative assessment tool for science teachers to adopt for the topic of energy. Eight high school science teachers marked students' concept maps using an itemized holistic marking guide. Their marking was compared with the researchers' marking and the scores…

This article explores the processes of writing in science and in particular the "complex performance" of writing a scientific argument. The article explores in general terms the nature of scientific argumentation in which the author-scientist makes claims, provides evidence to support these claims, and develops chains of scientific…

Proven through more than a decade of rigorous research to be effective with both teachers and students, "Making Sense of SCIENCE" helps teachers gain a deep and enduring understanding of tricky science topics, think and reason scientifically, and support content literacy in science, thereby increasing student achievement. The materials…

Media headlines often announce that U.S. students do not shine in international comparisons in mathematics and science, but seldom does any one focus on the specifics of how instruction differs among countries and how U.S. educators can alter their practices to improve student achievement. Examining key findings from the Third International…
