Results from a study of 16 community college students are presented. The research question concerned how students reasoned about p-values. Students' approach to p-values in hypothesis testing was procedural. Students viewed p-values as something that one compares to alpha values in order to arrive at an answer and did not attach much meaning to…

Understanding genetic drift is crucial for a comprehensive understanding of biology, yet it is difficult to learn because it combines the conceptual challenges of both evolution and randomness. To help assess strategies for teaching genetic drift, we have developed and evaluated the Genetic Drift Inventory (GeDI), a concept inventory that measures…

This paper describes the results from a qualitative study of 72 preservice teachers' initial ideas about contextualizing science instruction with language minority students. Participants drew primarily on local ecological and multicultural contexts as resources for contextualizing instruction. However, preservice teachers enrolled in the bilingual…

Many students may not see it that way, but that is because they have little understanding of what it means to appreciate history. The traditional high school history survey courses, US History and world history, provide an overview of "everything that ever…

Modern agriculture poses ecological problems and opportunities, which defy simple democratic reform without an educated citizenry. Developing an educated citizenry can be accomplished by further developing agricultural literacy in elementary education. While benchmarks for agricultural literacy have been produced, relatively little attention has…

This study sought to determine what elementary teachers know about student science misconceptions and how teachers address student misconceptions in instruction. The sample included 30 teachers from California with at least 1-year of experience teaching grades 3, 4, and 5. A semistructured interview was used. The interview transcripts were…

Misconceptions about HIV/AIDS among Latino adults (N=454) in California were examined using data from a population-based telephone survey conducted in 2000. Common misconceptions concerning modes of HIV transmission included transmission via mosquito or animal bite (64.1%), public facilities (48.3%), or kissing someone on the cheek (24.8%). A…

Challenges vague, underconceptualized notions of teacher professional community. Findings from an exploration of two California middle-school teacher communities suggest that current models obscure significant differences in beliefs and practices. One community stresses teachers' individual rights and responsibilities; the other is driven by a…
