Abstract (2. Language): 
Problem Statement: Research studies have indicated that students correctly solve algorithmic questions about a concept without having a basic understanding of it. Parallel to this, in our schools, teachers have generally determined their students’ chemistry achievement by using algorithmic questions. This is an important problem for an effective chemistry education. Purpose of the Study: The purpose of the present study is to compare prospective science teachers’ performance on conceptual and algorithmic chemistry questions. Method(s): The descriptive survey model was adopted for the study. A total of 92 student teachers in first year enrolled in science teacher education department of a Faculty of Education in the eastern Blacksea region participated in the study. A test consisting of 12 questions, half of which are algorithmic and the others are conceptual, were developed and it covered six chemistry topics; acid and base, mole concept, chemical equilibrium, gases, dissolving, and finding molecular formula. The test included one conceptual question and one algorithmic question related to each topic. Students’ performances on algorithmic and conceptual questions were statistically analyzed by using independent samples t-test. Findings and Discussions: The results of t-test showed that there was a statistically significant difference between conceptual questions and graphical questions (p < 0.05). This result was consistent with results of previous studies. While 60% of students prefer algorithmic questions, 20% of them prefer conceptual questions, which is consistent with t-test findings. 50% of the students solved correctly both conceptual and algorithmic questions about all concepts under investigation. Although 27% of them solved algorithmic questions correctly, they cannot solve conceptual questions in same topics. While 14% of students solved conceptual questions correctly, they cannot solve algorithmic questions. 9% of the students cannot solve both conceptual and algorithmic questions. Conclusions and Recommendations: Most of the students showed higher performance on solving algorithmic questions requiring mathematical calculations than conceptual questions. This difference in student performance between algorithmic and conceptual questions was found statistically significant. In a similar manner, most of the students preferred algorithmic questions rather than conceptual questions. High performance on conceptual questions could be a predictor in explaining students’ performance on algorithmic questions. Teachers and teacher educators should be awareof results of this and similar studies with in-service training programs.
Abstract (Original Language): 
Bu çalışmanın amacı, ilköğretim fen bilgisi öğretmen adaylarının kavramsal ve algoritmik kimya sorularındaki performanslarını karşılaştırmaktır. Çalışmaya, Doğu Karadeniz bölgesinde yer alan bir eğitim fakültesinin ilköğretim fen bilgisi öğretmenliği programında öğrenim gören toplam 92 birinci sınıf öğretmen adayı katılmıştır. Çalışmanın yürütülmesinde betimsel tarama modeli benimsenmiştir. Gazlar, asit-baz, molekül formülü bulma, denge, çözeltiler ve mol kavramı konularına yönelik altı kavramsal altı algoritmik toplam 12 sorudan oluşan bir test geliştirilmiştir. Testten elde edilen veriler, bağımsız örneklemeli t-testi kullanılarak karşılaştırılmıştır. Sonuçlar, öğretmen adaylarının genel olarak algoritmik sorularda kavramsal sorulardan daha yüksek başarıya sahip olduklarını göstermektedir. Kimya öğretiminde kavramsal anlamayı merkeze alan, sayısal işlemlerden ziyade kavram öğretimine ağırlık veren, öğretim yöntemlerinin ve ölçme-değerlendirme yaklaşımlarının kullanılması önerilmektedir.
