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…

The present research investigates the contribution of an interactive educational virtual environment on milk pasteurization to the learning outcomes of 40 students in a technical secondary school using SOLO taxonomy. After the interaction with the virtual environment the majority of the students moved to higher hierarchical levels of understanding…

In Uganda, curbing the spread of HIV/AIDS has largely depended on public and private media messages about the disease. Media campaigns based on Uganda's cultural norms of communication are metaphorical, analogical and simile-like. The topic of HIV/AIDS has been introduced into the Senior Three (Grade 11) biology curriculum in Uganda. To what…

This report argues that there exists a pervasive tendency for analogies to contribute to the development of entrenched misconceptions in the form of reducing complex new knowledge to the core of a source analogy. The report presents a taxonomy of ways that simple analogy induces conceptual error and an alternative approach involving integrated…

Elizabeth C. Knight left the suburbs to major in English at Boston University. Knight currently lives in New York City and works for an afterschool program that deals primarily with inner city youth. Having grown up in an affluent neighborhood, Knight dispels many of the myths centered around growing up in beautiful, safe, wealthy suburbs, saying…
