Found grades in science achieved by tenth-grade general science students correlated with their scores on Propositional Logic Test. The students' ability level was consistently related to the pattern of errors they committed on that measure. Mean scores were lowest on a subtest of ability to use the bicondition and implication, higher on the…

Focuses on the conceptual change processes of 17 fourth-grade students as they grapple with the abstract concept of human rights. Discusses limitations and successes in students' learning within the framework of conceptual change and motivation research. (CFR)

The "at-risk" designation attached to low-achieving children frequently sets them up for failure. Remedial programs are often ineffective, and skill drills rob students of in-context reading opportunities. Models like Success for All are so prescriptive that students cannot participate in open-ended discussions of literature. Unjust…

Process/product instruments of the 1970s attempt to evaluate teaching based on classroom observations. Performance-based teacher assessment is an ineffective, inappropriate method that does not truly assess teaching. Alternative methods (portfolios, student evaluations, peer evaluation, dossiers, and 360-degree feedback) support professional…

The Northwest Regional Educational Laboratory's Equity Center has identified several disturbing trends, including renewed physical separation, cultural biases, lower teacher expectations, and ability grouping, resulting in inequitable policies and practices and unsatisfactory student achievement. Seven key ameliorative components, including access…

A primary objective for science education is to impart robust knowledge that has applicability to real-world problems. This article presents research investigating the relationship between adolescents' conceptual understanding of the biological basis of HIV and critical reasoning. Middle and high school students were interviewed about their…

There is a widely and deeply held belief on the part of the author's white colleagues that racism is something done by individuals through overt or covert actions against other individuals. Sometimes this belief is tied to one specific characteristic--skin color. Some would believe that they cannot commit racist acts against anyone who looks like…

In a two-day workshop, 12 teachers who had not previously used graphics calculators not only learnt how to use a calculator but also completed calculator tasks designed to explore their misconceptions and then learnt about students' difficulties. Observation of lessons taught subsequently by 6 of the teachers, and interviews with 15 of their…

Since the first toy libraries opened in the 1960s and 1970s to support families of children with special educational needs, they have expanded to serve broader communities. Toy libraries do more than lend toys: they can provide family support services and specialist support to families with children with special educational needs, benefit…

This book offers broad, practical strategies for teaching science and engineering courses and describes how faculty can provide a learning environment that helps students comprehend the nature of science, understand science concepts, and solve problems in science courses. The student-centered approach focuses on two main themes: reflective writing…

The role that independent colleges and universities play in meeting the national interest of providing educational opportunity is not always recognized. The information in this report demonstrates how independent colleges and universities provide affordable access to students from a diverse array of backgrounds. Students who attend these…

This paper examines the development of science content knowledge of elementary teachers (N=25) as a result of participating in a summer science Institute funded by the Massachusetts Department of Education and the National Science Foundation. The institute was designed to integrate the physical, life, and earth sciences by addressing the National…

One result of the ambiguity surrounding future jobs is a number of myths not only about what jobs will be available and what they will be like but also about how to prepare for them. The first myth is "40 years and out," the notion that people will work continuously with one organization until retirement. The reality is that individuals need to be…

The purpose of this study was to investigate the effectiveness of using conceptual change texts accompanied with small group work on ninth grade students' learning of ecology. The developed texts were constructed to remediation of students' misconceptions with accommodated new ones about ecology. Conceptual change texts were implemented in an…

This paper describes the design and results of a study carried out with elementary pupils ages 8-9 years on the topic of sinking and floating, with the aim of checking the validity of a general scheme for classroom activities based on a constructivist perspective. Children's "ways of looking" at buoyancy and the production of materials…
