Learning science in a meaningful way involves more than doing a series of activities directed towards anticipated outcomes. Learning science entails teacher and children talking together as "co-constructors" of knowledge (Barnes, 1976). Karen Gallas (1995) has described her long-term observations of the kinds of talk which contribute to…

The basic contention that a more imaginative, creative, and challenging approach will result in better achievement in SATs--in other words, if the children enjoy their science they will do better--was the basis of a project at Oxford Brookes University. The project was devised to encourage and enable the participating teachers to develop a…

Biology students in their first year at university have difficulty understanding the abstract concepts of photosynthesis. The traditional didactic lecture followed by practical exercises that show various macroscopic aspects of photosynthesis often do not help the students visualise or understand the submicroscopic (molecular-level) reactions that…

An interdisciplinary course centered on mathematical ideas (involving infinity and geometry) is described. The course was developed by the authors, both mathematicians, as a vehicle for engaging students in learning about mathematical ideas that are rarely found in the general undergraduate curriculum. The course was offered to honors students…

An appropriate understanding of the nature of the scientific enterprise (NOSE) is a key element of scientific literacy and can arguably be influenced through an exploration of the history of science. An elective, undergraduate History of Science course was organized in the form of small-group discussion-based inquiries into the history of science…

This paper reports a 4-month study that investigated the effectiveness of curriculum materials incorporating the history of science (HOS) on learning science, understanding the nature of science (NOS), and students' interest in science. With regards to these objectives, three different class contexts were developed with three main types of…

Web-based learning environments are a great asset only if they are designed well and used as intended. The urgency to create courses in response to the growing demand for online learning has resulted in a hurried push to drop PowerPoint notes into Web-based course management systems (WBCMSs), devise an electronic quiz, put together a few…

The study explored the effectiveness of a discussion support taxonomy used in a course in which graduate students served as online discussion leaders. The students' ability to effectively use the taxonomy as a support tool to facilitate the discussions was examined. A content analysis of the discussion transcripts was conducted, and findings…

The shape and form of effective teacher-pupil talk has recently become the focus of attention within policy guidelines such as the National Numeracy and Literacy Strategies. Prior to this, research on classroom discourse has established that social context plays an important role in determining the quality of teacher-pupil talk since it directs…

The aim of this research was to investigate the way in which parents of Grade One learners in a traditionally black school facilitate learning to help their children acquire mathematical skills and knowledge in mathematics, and also to help them become confidently involved in and give meaning to mathematics learning in Grade One. A questionnaire,…

Elementary education students enrolled in an experimental mathematics course participated in this study. The course is taught using a social constructivist approach and is designed to improve students' mathematical problem-solving ability and deepen their understanding of mathematics. The research question for the present study is as follows: In…

The author found "This Bridge Called My Back" at the local public library when she was, at age thirty-three, finally beginning to write again, and write honestly. There were Indian voices in "Bridge"--a few poems or personal narratives that moved her, but which barely began to represent the range of the writers or the…

This study examined the effects of response time and message content on the growth patterns of discussion threads in computer-supported collaborative argumentation. Event sequence analysis was used to measure response times between threaded messages and responses containing arguments, evidence, critiques, evaluations, and other comments from…

This study examined the teaching of controversial public issues (CPI) in middle and high school social studies classes. I sought to better understand the instruction and conceptions undergirding the instruction of secondary social studies teachers who were nominated by discussion experts as especially skillful at teaching their students to…

Human sexuality is a significant issue for educators to understand and teach about, and for young people to learn about. The development of interactive multimedia technologies has added a range of new dimensions associated with designing pedagogies for sex education on Interactive Multimedia (IMM). Here, a module on CD-Rom on Sexuality and Human…
