In recent years a number of reports have raised alarm over the deteriorating state of U.S. science and technology (S&T) competitiveness. But a recent report by the RAND Corporation, "U.S. Competitiveness in Science and Technology," argues that the U.S. continues to lead the world. RAND's report has been interpreted to suggest that the "clarion…

The aim of this study was to investigate effectiveness of PDEODE (Predict-Discuss-Explain-Observe-Discuss-Explain) teaching strategy in helping students make sense of everyday situations. For this, condensation concept was chosen among many science concepts since it is related to many everyday-life events. Forty-eight eleventh graders students…

With universities, teacher education institutions, and high schools gearing up heavily in online course delivery in every discipline, science educators specifically are asking themselves "How do we provide this access to our students and still maintain our pedagogical integrity in science instruction?" This question seems to be at the heart of a…

One of the important misconceptions in the American view of poverty is that people are poor because they do not work. This article presents an exercise, the "bottom line," which helps dispel students' misconceptions about the working poor. Through extensive primary-data collection and assembling a budget for low-skilled workers, the exercise: (1)…

Four myths that underlie persistent, but ineffective, practices in early literacy education are analyzed in this article. Such analysis is essential because literacy disadvantage ultimately is an issue of equity--a matter of social justice. Research shows that these practices can be refuted and that optimal early literacy outcomes are possible for…

Debugging is often difficult and frustrating for novices. Yet because students typically debug outside the classroom and often in isolation, instructors rarely have the opportunity to closely observe students while they debug. This paper describes the details of an exploratory study of the debugging skills and behaviors of contemporary novice Java…

The research reported in this case study explores the understanding of stoichiometry and related concepts of Thai science students in grades 10 and 11 after major national curriculum reforms. Students' conceptions and alternative conceptions were investigated using a questionnaire--the "Stoichiometry Concept Questionnaire" (SCQ) (N =…

Int his essay, the authors identify and problematize the claims and activities of four think tanks supported by contributions from the Bill and Melinda Gates Foundation. Kovacs and Christie attempt to show that these contributions support scholars and research of dubious quality, engage in political science abuse, and perpetuate discourses and…

This article explores language assessments and policies that Latino students and others from immigrant backgrounds face as they graduate from high school and attempt to enter community colleges. Focusing on California, the authors examine the assumptions that underlie these assessments and policies. They argue that the policies signal different…

The Earthquake Machine (EML), a mechanical model of stick-slip fault systems, can increase student engagement and facilitate opportunities to participate in the scientific process. This article introduces the EML model and an activity that challenges ninth-grade students' misconceptions about earthquakes. The activity emphasizes the role of models…

This paper shows how concept mapping can be used to measure the quality of e-learning. Six volunteers (all of them 3rd-year medical students) took part in a programme of e-learning designed to teach the principles of magnetic resonance imaging (MRI). Their understanding of MRI was measured before and after the course by the use of concept mapping.…

This article reports recent research investigating the use of retrospective miscue analysis (RMA) as an instructional strategy with proficient second-language (L2) readers. RMA aims to heighten a reader's awareness of the reading process by involving readers in detailed analysis of their oral reading behavior. Using a cross-case analysis of three…

Significant instructional changes in mathematics will be achieved only if each educator involved with school mathematics engages in a personal rethinking of various aspects of mathematics instruction and identifies some concrete ways in which his or her current practice could be modified to reflect the results of such rethinking. This book is…

Myth plays a role in shaping the way outdoor educators develop pedagogy and curriculum, and its influence needs to be critically evaluated in such processes. In mythic narratives about Australian culture, the Burke and Wills expedition of 1860 is an icon: a story whose significance has often been evoked in discussion of a national ethos and…

This paper introduces issues related to the role of intuitive knowledge in physics learning. Phenomenological primitives, which form the base level for intuitive explanations in the research, are discussed. Three primary questions are the focus of this paper: (1) What role, if any, does intuitive knowledge play in physics problem solving? (2) How…
