Investigation of Prospective Teachers’ Scientific Reasoning for Determining the Heat of an Unusual Reaction

Öz:
Students' evaluation of findings that do not match hypotheses they have established based on theircurrent understanding and at the same time do not expect has an important role in their conceptual changes ininquiry activities. One of the issues that may encounter unexpected findings is the issue of chemical energy. Moststudents believe that spontaneous reactions will be exothermic, and that endothermic reactions can occur byexternal heating. In this study, the scientific reasoning of the prospective teachers who participated in an inquirybased experiment about deciding the heat of a spontaneous endothermic reaction as a rare phenomenon in dailylife was examined. The study was conducted with 58 prospective teachers in the first year of a faculty of education.The data were collected from prospective teachers’ experiment sheets and interviews . When the hypothesesestablished by the participants and their decisions about the heat of the reaction were examined, it was determinedthat some of them exhibited consistent scientific reasoning, while many showed confirmation bias; while some ofthem changed their alternative understanding, most of them did not. Based on these results, it may be suggested toconduct studies examining the scientific reasoning of learners towards different phenomenon.

Öğretmen Adaylarının Sıra Dışı Bir Tepkimenin Isısını Belirleme Konusunda Sahip Oldukları Bilimsel Muhakemelerinin İncelenmesi

Öz:
Öğrencilerin mevcut anlayışlarına dayalı olarak kurdukları hipotezlerle uyuşmayan ve aynı zamanda beklemedikleri bulguları değerlendirmelerinin, onların sorgulayıcı araştırma etkinliklerindeki kavramsal değişimlerinde önemli yeri vardır. Beklenmedik bulgularla karşılaşılabilecek konulardan biri kimyasal enerji konusudur. Öğrencilerin çoğu istemli tepkimelerin ekzotermik olacağına, endotermik tepkimelerin ise dışarıdan ısıtmayla gerçekleşebileceğine inanmaktadır. Bu çalışmada günlük hayatta sık karşılaşılmayan bir olgu olarak istemli endotermik bir tepkimenin ısısına karar vermeyle ilgili bir sorgulayıcı araştırma deneyine katılan öğretmen adaylarının bilimsel muhakemeleri incelenmiştir. Çalışma bir eğitim fakültesinin birinci sınıfındaki 58 öğretmen adayı ile gerçekleştirilmiştir. Veri toplamada öğretmen adaylarının deney föylerinden ve onlarla gerçekleştirilen görüşmelerden faydalanılmıştır. Katılımcıların kurdukları hipotezler ve tepkimenin ısısıyla ilgili kararları incelendiğinde, bazılarının tutarlı bilimsel muhakemeler sergilerken birçoğunun doğrulama yanlılığı gösterdiği; yine bir kısmının alternatif anlayışlarını değiştirirken, çoğunun değiştirmediği belirlenmiştir. Bu sonuçlara dayanarak, öğrencilerin farklı olgular karşısındaki bilimsel muhakemelerinin inceleneceği çalışmaların yapılması önerilebilir.
