In this study, 120 tenth-grade students from 8 schools were examined to determine the extent of their ability to perceive the human body as a system after completing the first stage in their biology curriculum--"The human body, emphasizing homeostasis". The students' systems thinking was analyzed according to the STH thinking model, which roughly…

The world over, secondary school science is viewed mainly as a practical subject. This may be one reason why effectiveness of teaching approaches in science education has often been judged on the kinds of practical activity with which teachers and students engage. In addition to practical work, language--often written (as in science texts) or oral…

Of concern is an international trend of students' increasing reluctance to choose science courses in both their final years of secondary school and tertiary levels of education. Research into the phenomenon indicates an influencing factor to be the "uninteresting curriculum" (OECD "2006") of school science. This paper presents an exploration of…

Science educators often suggest that students should learn science in ways and settings that bear family resemblance with "the real thing." Internship in science laboratories constitutes one such way in which students may learn science and learn about science. However, very little is known about "how" participants experience a science internship…

This article reports on the third year of a three-year longitudinal investigation into six secondary students' understanding of optics at a secondary school level. In the third year of this investigation the students, who by now were in Year 12, underwent a teaching sequence that centred on the teaching and learning of physical optics and quantum…

Describes a study of the influence of the Cognitive Acceleration through Science Education (CASE) program on the scientific creativity of secondary school students. Scientific creativity is measured by the Scientific Creativity Test for Secondary School Students. Results indicate that the program did promote the overall development of scientific…

Investigates how microcomputer-based laboratory (MBL) activities specifically designed to be consistent with a constructivist theory of learning support or constrain student construction of understanding. Analysis of students' discourse and actions reveal that students invented numerous techniques for manipulating data in the service of their…

Investigates whether pupils aged 12-15 years perceive physical quantities as intensive or extensive. Written questionnaires were administered to 300 pupils comprising four tasks for each intensive quantity, density and pressure. Analysis reveals three models of consistent pupils' reasoning.

Explores a case study of a class of 10th grade students whose learning of genetics involved activities using BioLogica, a computer program that features multiple external representations (MERs). Findings indicate that the MERs in BioLogica contributed to students' development of genetics reasoning by engendering their motivation and interest but…

Interaction between science and design and technology (D&T) in schools is seen by many educationalists and industrialists as being desirable. During the period 1970 to 1990 progress was made in the UK, however the advent of the national curriculum compartmentalised subjects thus hindering further progress. Bodies in the UK such as the Office for…

Conceptions of sustainable development were elicited using a questionnaire completed by three cohorts of postgraduate students starting a secondary science teacher-training course (N = 123). Qualitative responses were analysed in three ways: (i) development of categories to capture features of sustainable development; (ii) scrutiny of individual…

Investigates the use of the World Wide Web (WWW) as a research and teaching tool in promoting self-directed learning groups of 15-year-old students. Discusses the perceptions of students of the effectiveness of the WWW in assisting them with the construction of knowledge on photosynthesis and respiration. (Contains 33 references.) (Author/YDS)

Studies career choice and retention of 19 secondary science education graduates using a biographical approach. Compares autobiographical papers written as preservice teachers and rewritten as career teachers for intrinsic reasons for vocational choice. Involves early vocation teachers and those who chose science teaching later in their higher…

Reports on two inter-related studies that examined the use of non-traditional writing strategies within secondary school science classrooms. The first study involved Year 10 students who incorporated one letter writing experience into the learning sequence when studying genetics. The second study was with Year 9 students who used both a…

Investigates, using Marton's theory of the structure of awareness, the aspects that students discerned and brought into their focal awareness while they studied four science stories in an instruction designed for fostering understanding of the nature of science (NOS). The data showed that when students studied the stories, many focused only on one…
