The purpose of this study was to investigate the nature of students' responses to a cross-cultural science unit entitled "Maintaining health." The unit was designed to help students to build bridges between their traditional practices and beliefs and western science concepts. This paper reports students' responses to a pre-test and post-test, and…

We investigated for the first time the genetic and environmental aetiology behind scientific achievement in primary school children, with a special focus on possible aetiological differences for boys and girls. For a representative community sample of 2,602 twin pairs assessed at age nine years, scientific achievement in school was rated by…

Many studies into learners' ideas in science have reported that aspects of learners' thinking can be represented in terms of entities described in such terms as alternative conceptions or conceptual frameworks, which are considered to describe relatively stable aspects of conceptual knowledge that are represented in the learner's memory and…

This study, carried out in England, examined the variation of attitudes towards science over the first three years of secondary schooling and with gender. The study in question was part of an evaluation of the "Lab in a Lorry" project, and involved 932 pupils completing a pre-measure questionnaire containing items looking at six separate attitude…

In the studies reported here, we investigate the effects of context on students' molecular-level ideas regarding aqueous solutions. During one-on-one interviews, 19 general chemistry students recruited from a two-year community college and a research university in the United States were asked to describe their molecular-level ideas about various…

This study examined the use of form and function analogy object boxes to teach second graders (n = 21) animal adaptations. The study used a pretest-posttest design to examine animal adaptation content learned through focused analogy activities as compared with reading and Internet searches for information about adaptations of animals followed by…

In an action research study, 66 students from Year 11 in an Australian school were shown the colour of methyl violet indicator in some hydrochloric acid solutions, and then in an acetic acid solution. The intent was to create a cognitive conflict, resolution of which would lead to an understanding of the concept "weak acid". Student learning…

The interrelationship between senior high school students' science achievement (SA) and their self-confidence and interest in science (SCIS) was explored with a representative sample of approximately 1,044 11th-grade students from 30 classes attending four high schools throughout Taiwan. Statistical analyses indicated that a statistically…

Research into classroom interactions has shown that talk that promotes reasoning can help children in their learning of science. Such talk can only be generated when teachers are willing to take a dialogic approach that is stimulating and provides opportunities for children to articulate their ideas. This research set out to determine whether the…

The assumption that scientific knowledge would bring an end to religious belief has challenged many scholars, particularly since such a belief persists even among those devoted to scientific activities. In this paper the occurrence and nature of religious belief in groups of life scientists working in the UK and Brazil is discussed in the context…

Quantum numbers and electron configurations form an important part of the general chemistry curriculum and textbooks. The objectives of this study are: (1) Elaboration of a framework based on the following aspects: (a) Origin of the quantum hypothesis, (b) Alternative interpretations of quantum mechanics, (c) Differentiation between an orbital and…

This study is a secondary analysis of data from the 1995 administration of the Third International Mathematics and Science Study (TIMSS). The purpose is to compare the breadth, depth, and recurrence of the typical physics curriculum in the United States with the typical curricula in different countries and to determine whether there are…

The purpose of this study was to examine whether science and non-science major students have different scientific epistemological views (SEVs). A multidimensional instrument previously developed by the authors was used to assess differences in college students' SEV of various aspects. A total of 220 freshmen (42% science and 58% non-science…

This paper reports on the reality of classroom-based inquiry learning in science, from the perspectives of high school students and their teachers, under a national curriculum attempting to encourage authentic scientific inquiry (as practiced by scientists). A multiple case study approach was taken, utilising qualitative research methods of…

Preservice teachers enrolled in a two-part course entitled Investigations in Mathematics and Science (IMS) were provided inquiry-based mathematics and science instruction in order to develop both content and process skills. This investigation sought to determine the pedagogical nature of the course and the impact it had on its participants.…
