Wheeldon, R.; Atkinson, R.; Dawes, A.; Levinson, R. – Research in Science & Technological Education, 2012
Background and purpose: Chemistry examinations can favour the deployment of algorithmic procedures like Le Chatelier's Principle (LCP) rather than reasoning using chemical principles. This study investigated the explanatory resources which high school students use to answer equilibrium problems and whether the marks given for examination answers…

Yalcinkaya, Eylem; Tastan-Kirik, Ozgecan; Boz, Yezdan; Yildiran, Demet – Research in Science & Technological Education, 2012
Background: Case-based learning (CBL) is simply teaching the concept to the students based on the cases. CBL involves a case, which is a scenario based on daily life, and study questions related to the case, which allows students to discuss their ideas. Chemical kinetics is one of the most difficult concepts for students in chemistry. Students…

Chu, Hye-Eun; Treagust, David F.; Chandrasegaran, A. L. – Research in Science & Technological Education, 2009
A large scale study involving 1786 year 7-10 Korean students from three school districts in Seoul was undertaken to evaluate their understanding of basic optics concepts using a two-tier multiple-choice diagnostic instrument consisting of four pairs of items, each of which evaluated the same concept in two different contexts. The instrument, which…

Calik, Muammer; Ayas, Alipasa; Ebenezer, Jazlin V. – Research in Science & Technological Education, 2009
The study aims to demonstrate evidence of (a) students' conceptual change on solution rates; (b) students' sub-microscopic explanations of dissolution; and (c) retention of the concepts of solution rates. The sample consists of 44 Grade 9 students (18 boys and 26 girls) drawn purposively from two different classes (22 each) in the city of Trabzon,…

Atasoy, Basri; Akkus, Huseyin; Kadayifci, Hakki – Research in Science & Technological Education, 2009
The purpose of this study was to compare the effects of a conceptual change approach over traditional instruction on tenth-grade students' conceptual achievement in understanding chemical equilibrium. The study was conducted in two classes of the same teacher with participation of a total of 44 tenth-grade students. In this study, a…

Siorenta, Anastassia; Jimoyiannis, Athanassios – Research in Science & Technological Education, 2008
This paper reports on the examination of physics teachers' beliefs and perceptions of laboratory and ICT supported physics instruction. The findings indicate that the teachers in the sample were generally positive about the affordances offered by the physics lab and ICT in physics instruction. However, school culture context, mainly the need to…

Cleaves, Anna; Toplis, Rob – Research in Science & Technological Education, 2008
The practices and justifications of 15 pre-service science teachers in using ICT were explored by survey, observation and interview. Interactive whiteboards are frequently employed, although predominantly as projection screens for presentations, whilst datalogging and spreadsheets are used infrequently. Trainees incorporate ICT to enhance pupil…

Lewis, Tim; Barlex, David; Chapman, Colin – Research in Science & Technological Education, 2007
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…
