Enhancing Content Knowledge Of In-Service Science Teachers Through Model And Modeling, Naheed Perveen, Sadia Muzzafar Bhutta
Enhancing Content Knowledge Of In-Service Science Teachers Through Model And Modeling, Naheed Perveen, Sadia Muzzafar Bhutta
Institute for Educational Development, Karachi
The guiding question for this paper is; how does model and modeling enable student-teachers to develop a conceptual understanding of the cell as a structural and functional unit of living things? A teaching unit ‘The Cell’ was designed in view that models are a major teaching and learning tool for developing scientific thinking, whereas modeling means a process of forming representation. The teaching and learning strategies reported here encapsulated four modeling phases. Firstly, student-teachers modeled historical development of cell through a time line and role play and discussed the evolutionary and tentative nature of science. Secondly, the candy factory analogy …

Making Use Of Bilingual Interview Data: Some Experiences From The Field, Nelofer Halai
Institute for Educational Development, Karachi
This paper describes the challenges faced, and rules devised, while dealing with bilingual interview data as part of a life history study of a female science teacher’s conceptions of the nature of science while teaching in a school in Karachi. The interview data generated was both in Urdu and English, which underwent a number of processes (transcription, translation, and transliteration) to evolve into “interim texts,” to finally become a part of the data analysis process. I have called these translated materials “transmuted texts,” as they reflect the original, but have been recreated. This paper is significant because as globalization connects …

Taking “Stock” Of Pedagogical Content Knowledge In Science Education, Harcharan Pardhan, Alan Wheeler
Institute for Educational Development, Karachi
This article focuses on efforts of facilitate the development of MEd science students' conceptual understanding of content, pedagogy and pedagogical content knowledge (PCK). A basic premise of the approach taken was that to teach conceptually, students must learn conceptually. A four-step conceptual process was followed with the participants to help them actively construct knowledge about fundamental science concepts and enhance their confidence and enthusiasm for science teaching. Equivalent forms of an assessment instrument entitled the Science Test of Content Knowledge (STOCK), used as per- and post-performance measures, revealed a significant difference. The article describes the structured activities built into the …
Promoting Science Teacher Education Through Dissonance And Discrepancy, Nelofer Halai, Alan E. Wheeler
Promoting Science Teacher Education Through Dissonance And Discrepancy, Nelofer Halai, Alan E. Wheeler
Institute for Educational Development, Karachi
While inquiry in science teaching has found a great deal of acceptance (Colletet and Chiapetta, 1989), there is a growing recognition that educators need a wider repertoire of inquiry strategies applicable to various situations. One promising approach is through the use of so-called ‘dissonant’ or ‘discrepant events’. This concept of discrepancy can be traced to the early work of Festinger (1975) and his Theory of Cognitive Dissonance in which he stated that the creation of dissonance is psychologically very uncomfortable and motivates individuals to actively reduce the level of dissonance and thereby return to a state of greater equilibrium or …
