The purpose of this study was twofold. First, it was aimed to identify Turkish pre-service physics teachers' knowledge and understanding of the Moon, Moon phases, and other lunar phenomena. Second, the effects of model-based teaching on pre-service teachers' conceptions were examined. Conceptions were proposed as mental models in this study. Four…

This study examined university students' knowledge of and attitudes (n = 378) toward biotechnology in Slovakia, a conservative country where the distribution of genetically engineered products are banned by law. We found a significant positive correlation between attitudes and the level of knowledge; however, although students enrolled in biology…

"Primary Science Review's" original "Wobbly Bits" series of articles was born back in 1997, after a conversation about this problem at a meeting of the ASE Primary Committee. The conversation turned to primary science teachers' scientific learning journeys. Each one of them could recount a story where they had completely misunderstood an aspect of…

Perceptions of depression, attitudes toward depression treatments, help-seeking preferences, and perceived barriers to care were examined in a sample of 56 Latino immigrant men recruited from a primary health care clinic. Each participant was presented a vignette depicting an individual with major depression. Men described the vignette as a…

This paper identifies several areas of database modeling and design that have been problematic for students and even are likely to confuse faculty. Major contributing factors are the lack of clarity and inaccuracies that persist in the presentation of some basic database concepts in textbooks. The paper analyzes the problems and discusses ways to…

One of the most publicly celebrated figures in mathematics teaching during the last century was Jaime Escalante (dramatized in the film "Stand and Deliver"). The Escalante story aptly fulfills three prevailing myths about effective teachers: the Teacher is self-made, the Teacher is the expert, and everything depends on the Teacher. These…

This study investigated the effectiveness of conceptual change texts in remediating high school students' alternative conceptions concerning chemical equilibrium. A quasi-experimental design was used in this study. The subjects for this study consisted of a total 78 tenth-grade students, 38 of them in the experimental group and 40 of them in the…

This article concerns the tragedy of the misuse of power and the power of imagined inferiority. African Americans must lose misconceptions about the majority, heighten understanding about being Black in America and how that makes their children vulnerable to this nation's worst, stop fighting losing battles like affirmative action, and find and…

To do solid academic research, college students need to look beyond the computer search engine. This short, practical book introduces students to the important components of the information-seeking process. "The Elements of Library Research" provides a foundation for success in any research assignment, from a freshman paper to a senior thesis.…

What is the capacity of online programs? Can these types of programs enroll more students than their face-to-face counterparts or not? This article looks at research on achieving cost-efficiencies through online learning, identifies the parts of an online program that can be changed to increase enrollments, and discusses whether a program's…

Teachers who attempt to promote metacognitive learning strategies in their pupils usually encounter resistance because the pupils believe that they should be instructed by a teacher. One step in overcoming such resistance is to help students to recognize and discuss their implicit views. This document describes a repertory grid which can be used…

The purpose of this study was to investigate senior high school students' difficulties predicting the existence of hydrogen bridge bonds between organic molecules, investigate students' difficulties predicting the relative boiling points of simple organic compounds, and develop test questions that enable teachers to quickly get information about…

To examine the effects of students reading multiple documents on their perceptions of a historical event, in this case the "discovery" of America by Christopher Columbus, 85 high school freshmen read 3 of 4 different texts (or sets of texts) dealing with Columbus. One text was an encyclopedia article, one a set of articles from…

The existence of probability misconceptions at all levels has been well documented. Furthermore, these misconceptions have been shown to be widespread and highly resistant to change. Previous research has shown considerable success in overcoming misconceptions in the short term by basing the knowledge reconstruction process on problems which draw…

A study investigated the relationships among prior topic knowledge, information in elementary science text, and the construction of visual representation of key text ideas. Eight preservice elementary teachers were first interviewed on two topics in science ("how plants get their food" and "air and weather"); then they read…
