Background: Chronotype refers to individuals' preference for morning or evening activities. Its two dimensions (morningness and eveningness) are related to a number of academic outcomes. Aims: The main goal of the study was to investigate the incremental validity of chronotype as a predictor of academic achievement after controlling for a number…

Describes an activity in which students look at photographs of different cats to determine the genotypes of the various characteristics observed. Provides a student worksheet. (MDH)

This manual is organized around the concept of chemical change as used to explain everyday phenomena. It concentrates on three interrelated aspects of chemical change: (l) scientific knowledge; (2) technological applications; and (3) societal issues. The unit is divided into four episodes or segments of instruction with suggested time allotments.…

Examined are tenth-grade Western Australian students' conceptual knowledge of gravity and the motion of the planets. Students were interviewed with seven cards, and a four-item diagnostic test based on the interview data on the first four cards was developed. A total of 113 students' responses to the test are summarized. (YP)

The purpose of this study was to explore the utility of the Theory of Planned Behavior for predicting the behavioral intentions of teachers enrolled in the Institute in Physical Science. The study investigated three determinants of teachers' behavioral intentions set forth in the theory of planned behavior, namely attitude toward the behavior,…

Examined is the effectiveness of a smoking-prevention program in modifying high school students' attitudes and values in such categories as health, peer pressure, and social image as related to smoking. The intervention lasted four to six weeks within the framework of ninth- and tenth-grade biology classes. (Author/YP)

The purposes of this study were to determine the level of achievement of United States advanced science students in an international context and to identify school factors affecting the science achievement of the students. The Second International Science Study (SISS) Advanced Science Achievement Tests included international common items which…

High school biology teachers (N=18), and one 10th-grade class of each teacher, were given the Nature of Scientific Knowledge Scale at the beginning and end of a school year to determine their conceptions of the nature of science. Results (such as students not possessing "adequate" conceptions of science) are reported and discussed. (JN)

This manual is designed to provide teachers with practical information to assist them as they implement the Science 10 program in their classrooms. The introduction of the Science 10 program in Alberta provides an opportunity for teachers to move out of their particular discipline of expertise and explore with their students the larger area of…

Designed to focus on teaching for higher-level cognitive learning, this study measured student perceptions of psychosocial aspects of their classroom learning and involved a team of six researchers. The study consisted of an intensive 10-week investigation of two above-average science teachers in a suburban high school in Perth, Western Australia.…

Investigated the consequences of teacher-student cognitive style (field dependence- FD and independence- FI) matches and mismatches on student achievement in biology. Results suggest that whereas FI students may be taught by and achieve equally well with either FI or FD teachers, FD students are more successfully taught by FI teachers. (JN)

This report concerns a descriptive study undertaken in 1982-1983 as part of the Second International Science Study (SISS) under the auspices of the International Association for the Evaluation of Educational Achievement (IEA) for the purpose of examining key elements of K-12 science instruction in the United States. Special attention was directed…

While logical reasoning skills are related to success in science, the relationship between thought and formal logic is not clear. Propositional Logic Test (PLT), error patterns of students' interpretations of logical proposition, and developmental patterns of the error type are described. Examined is the relationship between logical reasoning…

This is a qualitative study of science teaching for non-academic students in secondary school. Evidence from earlier studies suggested that few variations in teaching strategies are being used for non-academic students. This investigator categorizes certain pertinent teaching features which, if emphasized, have the potential to enhance the…

Data were collected by pencil-and-paper instruments from 33 students in grade 10 in Perth, Western Australia. Data indicated that students were only slightly knowledgeable about energy and energy conservation; they had slightly positive attitudes toward energy conservation. (MNS)
