BİLİMİN DOĞASINI DEĞERLENDİRMEK İÇİN KAVRAM HARİTALARININ KULLANIMI ÜZERİNE BİR ÖZ-İNCELEME ÇALIŞMASI

Bu çalışma bilimin doğasını öğretmek üzere kendi pedagojik alan bilgimizi incelediğimiz ve geliştirdiğimiz bir öz-inceleme self-study çalışmasıdır. Bu çalışmada bir ilköğretim fen öğretimi yöntemleri dersinde fen bilgisi öğretmen adaylarının bilimin doğası ile ilgili anlayışlarını değerlendirmek üzere kullanılan kavram haritalarının iki farklı kullanım şeklini keşfettik. Katılımcıları iki gruba ayırdık. 1. Gruba kavram haritalarını oluştururken bilimin doğasının yönlerini başlangıç noktası olarak almaları, 2. gruba isekendi “bilim” kavramlarını oluşturmaları söylendi. Çalışma sonunda bulgular 1. grupta yer alan katılımcılara verilen bilimin doğası yönlerinin bağlantıları kurmakta onların işini zorlaştırdığını gösterdi. Diğer yandan, 2. grup ilişkili kelimeleri bulmakta zorluk çekti. Bu bulgulara dayanarak her iki kavram haritası oluşturma yönteminin farklı değerlendirme amaçlarıyla kullanılabileceği ve bilimin doğası öğretiminin farklı aşamalarında işe yarar olduğunu söyleyebiliriz.

A Self-Study of the Use of Concept Mapping to Assess NOS

We undertook a self study to examine and develop our pedagogical content knowledge for teaching the nature of science. We explored two different uses of concept mapping to assess preservice teachers‟ ideas about the nature of science NOS in an elementary science methods course. The class was divided into two groups. Group 1 was provided with aspects of NOS as starter concepts for their maps, while Group 2 was asked to develop their own concepts related to “science”. We found that being given the NOS aspects constrained Group 1‟s ability to expand the connection of the main concept with other related words. On the other hand, Group 2 had difficulty moving beyond brainstorming related concepts. Based on this, we suggest that these two methods for concept mapping can be best used for different assessment purposes and at different points in NOS instruction
