"National Science Education Standards" (1996), published by the National Research Council, recommends that students learn to explain Moon phases and eclipses by the time they graduate from eighth grade. It is clear from the research literature, however, that misconceptions about Moon phases and eclipses are widespread and resistant to change, even…

Despite the best efforts of thousands of dedicated people, California's secondary schools are failing to adequately educate the majority of the state's English language learners (ELs). The purpose of this paper is to present a vision for high schools that will promote greater success for these students. This vision is based on Norm Gold's 30 years…

Drawing conclusions from the comparison of datasets using informal statistical inference is a challenging task since the nature and type of reasoning expected is not fully understood. In this paper a secondary teacher's reasoning from the comparison of box plot distributions during the teaching of a Year 11 (15-year-old) class is analyzed. From…

Positioned in relationship to reform literature calling for small schools "by design" and interpreting data from a case study of a high performing but low-SES district in a Midwestern state, this paper provides a basis for making sense of the apparent divergence in policies governing schooling structures in rural and urban places. Its…

Background: The total number of people with HIV (Human Immunodeficiency Virus) infection in India is estimated to be 10% of all global cases. People living with HIV in India often experience discrimination while receiving health care due to inadequate knowledge and fear among health care professionals. Data presented in this paper represents the…

This book provides practical strategies and tools for assessing and teaching even the most hard to reach English language learners across the content areas. Syrja offers educators the latest information on working with ELLs (including using formative assessments) and provides a wealth of classroom-tested models and measures. These tools have…

An administrator's daily life is full of decisions that often involve an "on the spot" solution. This paper discusses some of the principles involved in drawing inferences in research and decision making, and describes how a knowledge of decision-making errors can help administrators. The paper also describes a case study that…

This newsletter includes five articles on immigrant education that focus on successful school programs and educational policy issues. In "Immigrant Education from the Administrators' Perspective" (Pam McCollum, Juanita Garcia), three principals of south Texas secondary schools with successful immigrant programs discuss their views on the…

This book reports on the findings of a 3-year research project, Learning in Science, carried out in New Zealand.

The Probability Inquiry Environment (PIE) is being designed as a computer-mediated collaborative inquiry environment to aid middle school students in learning elementary probability. This paper reports on a study in which seventh grade students engaged in probabilistic reasoning while interacting with a preliminary version of PIE. By analyzing the…

This paper examines sixth-grade children's thinking related to solving ratio and proportion problems before these children had received any instruction in the domain. It explores unitizing and norming, one of the processes identified by both content analyses (Behr, Harel, Post, & Lesh, 1990); Harel, Behr, Post & Lesh, 1990) and research in…

The purpose of this study was to investigate the extent to which problem analysis facilitated the subsequent processing of expository text, both for novices and a comparison group. A text on osmosis consisted of six-pages and was used as reading material. The ninth-grade students were considered novices because they were unfamiliar with the…

During the summer of 1986 a conference funded by the National Science Foundation (NSF) was organized to assess the current state of cognitive research on the psychology of physics problem solving, and to examine the needs of physics instructors and instructional designers that must be addressed by a psychological theory of physics problem solving.…

The target of difficulty of the Educational Technology Center (ETC) Heat and Temperature Group is basic thermal physics, particularly the differentiation between heat and temperature. High school teachers often find that thermal concepts are very difficult for their students to master and attribute students' difficulties at least in part to the…
