Space-time plays a central role in the scientific study of learning trajectories. From a sociocultural perspective, the definition of a set of space-time coordinates enables researchers to identify and examine both the learning activities in which subjects participate and those life events relevant to understanding their learning processes. The…

Students have misconceptions about many scientific topics they encounter in the classroom--such misconceptions are especially rife in subjects with counterintuitive concepts. Several studies have copiously documented students' misconceptions in different science domains. Research shows that students' misconceptions can be resistant to change and…

Geoscientists analyze and integrate spatial and temporal information at a range of scales to understand Earth processes. Despite this, the concept of scale is ill defined and taught unevenly across the K-16 continuum. This literature review focuses on two meanings of scale: one as the magnitude of the extent of a dimension and the other as a…

This paper organizes and analyses over 500 geoscience misconceptions relating to earthquakes, earth structure, geologic resources, glaciers, historical geology, karst (limestone terrains), plate tectonics, rivers, rocks and minerals, soils, volcanoes, and weathering and erosion. Journal and reliable web resources were reviewed to discover (1) the…

Measurement can develop in the earliest years from children's experience, and it readily lends itself to real-world application. Focusing on research and practice, NCTM's 2003 Yearbook presents current thinking about the learning and teaching of measurement, including students' understanding, the mathematics of measurement, estimation and…
