Past research has indicated that a number of problems in the teaching of science in elementary classrooms are rooted in the preparation of inservice teachers. One continuing concern is elementary teachers' lack of science content knowledge. As indicated by numerous research studies reporting positive results, one method of addressing these…

This article presents a comparison between the professional and curricular conceptions of two samples of secondary education science teachers in Spain, who differed in their years of teaching experience and in whether or not they had participated in a long-duration scientific-pedagogical refresher course. Using the data from their responses to a…

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…

As a science subject leader and year 6 teacher in North Bristol, the author has spent the last few months exploring how an interactive whiteboard (IWB) can be used to teach science skills, particularly those that are repeatedly highlighted as problematic, such as analysis and evaluation of evidence. The IWB came with software called…

This article explores trainee teachers' conceptions and ideas about endangered bird species and their protection. The study involved 191 students majoring in kindergarten education, primary school natural science or secondary school biology education at the University of Ljubljana Faculty of Education, Slovenia. Data analyses showed that the…

In this study, the effect of problem-based learning on students' academic achievement and performance skills in a unit on the human excretory system was investigated. Sixty-one 10th grade students, from two full classes instructed by the same biology teacher, were involved in the study. Classes were randomly assigned as either the experimental or…

This article explores the synergy that can be created when concept-mapping techniques are used in collaboration with the construction of PowerPoint presentations to increase the richness of the learning experience. Some weaknesses of the typical PowerPoint format are highlighted with a description of how they can be overcome through a more…

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 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…

Student reflective ideas were examined with respect to Group Investigation (GI), which was employed in 11th grade Korean earth science classrooms. A modified GI method was implemented during the course of an action research effort consisting of two yearlong projects. Students' writings, which had been produced twice a year, were analyzed to reveal…

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…

It has been argued that design and technology can be used as a vehicle for teaching science and vice versa. In this paper, we report an investigation into Grade 6 students' understandings of concepts embodied in the Systems strand of a technology syllabus as they grappled with a unit of work in technology for the first time. The unit of work…

"Thinking schools" will be sites of learning for everyone declared the Singapore Prime Minister, Goh Chok and Minister of Education Teo Chee Hean's in 1997 also spoke on the model of "thinking schools, learning nation". Gardner's model was used for the thinking school model in Singapore, in order to develop critical and…

The complexity of science teaching requires science teachers to encounter a range of tasks. Some tasks are perceived as stressful while others are not. This study aims to investigate the extent to which different teaching situations lead to different stress levels. It also aims to identify the easiest and most difficult conditions to be regarded…
