In 2006-2007, we established a writing exercise in two large first-year biology courses. Overall, our exercise, which consisted of multiple drafts of a 500-word essay, offered students a good introduction to how editorial feedback can improve content and style in scientific writing. We discuss our goals, procedures, outcome, and students'…

This article articulates a framework for examining the quality of formative assessment practice and provides empirical evidence in support of one of its components. Based on a study of middle school science, the study examines the accuracy of teachers' judgments of students' understanding and the relationship of such accuracy to middle school …

The development of an interactive web-based science information literacy tutorial that introduces undergraduate science majors to basic components of scientific literature is described. The tutorial introduces concepts, vocabulary and resources necessary for understanding and accessing information. The tutorial content is based on the Association…

This article describes an engaging, data-gathering activity that allows students to explore relationships between latitude and average monthly temperatures of cities in the Western Hemisphere. This data-gathering activity covered interesting and important mathematical ground and engaged students from the start. While students searched for their…

This study investigated perceptions of 56 students in 4 general chemistry labs regarding their understanding of chemical concepts and processes. Conceptual understanding of scientific investigation was the focus. Students using a pre-lab guide for lab preparation were compared with students completing a traditional pre-lab assignment. Data sources…

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…

This book contains a series of engaging activities that offer students a chance to explore acids and bases using the special indicator properties of red cabbage juice. The activities allow students to discover acids and bases through their own experiments and interpretations. The skills of observing, recording results, comparing, classifying,…

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…

This book is written for people who tend to sit toward the back of the classroom during scientific lectures. It assumes that students remember nothing of what happened in their science classes. The book is divided into seven sections: (1) Magnetism; (2) Bending Light Waves; (3) Bacterial Stories; (4) Light Wave Craziness; (5) Homemade Science; (6)…

Young children in Australia enter early childhood education settings eager to make sense of the world that surrounds them. Their interest in every day experiences is evident in the range of questions asked, many of which are scientific in nature. Intended as a resource for adults working with 4-to 8-year-old children, this booklet provides an…

Piaget (1968) and Michotte (1963) studied children's perception of physical causality. While emphasizing perception, they deemphasized thinking. The present study extends research by these authors by identifying types of verbal thinking in preschoolers on the basis of judgment of three fundamental physical laws: the first law of static, the law of…

Describes a lesson that utilized inquiry to teach the students a scientific concept and to emphasize the fact that they shouldn't jump to conclusions. (LS)

Incorporates some ideas from a book by Galileo into a problem-solving format that challenges students. (LS)

Secondary science students were tested, using Piagetian tasks to determine their level of intellectual development, and then tested on scientific concepts classified as concrete or formal. Results showed significant multiple correlations between the scores on the tasks and the subject matter tests. (MLH)

Reviews research in the area of scientific classification of botany concepts. The acquisition, transfer, and ability to use cognitive skills were investigated. (CP)
