Abstract (2. Language): 
The purpose of this study is to investigate the effects of argumentation based on student-constructed ‘pre’ and ‘post’ laboratory concept maps on students’ attitudes towards chemistry laboratory in a university general chemistry course. Concept mapping has been used as a tool to carry out the argumentations about chemicalconcepts involved in general chemistry laboratory experiments between instructors and students, and among students. In the experimental group, students (N=41) performed their general chemistry laboratory experiments using individual, small and large group discussions based on students’ pre- and post- laboratory concept maps, whereas the control group students (N=43) performed their laboratory investigations using traditional approaches. A questionnaire to test the attitudes of students towards chemistry laboratory (QATCL) has been administrated to both groups as pre- and post-tests. The statistical analysis (ANCOVA) of results of QATCL post-test showed that there has been a significant difference favoring the experimental group with respect to students’ attitudes towards chemistry laboratory. Hence, it is found out that argumentative discourse founded on pre- and post-laboratory concept maps are more effective in improving students’ attitudes towards chemistry laboratory than traditional teaching methods.

Abstract (Original Language): 
Bu çalışmanın amacı, öğrencilerin üniversite genel kimya laboratuvarlarında hazırladıklarılaboratuvar öncesi ve sonrasıkavram haritalarına dayalıgerçekleştirilen tartışmaların derse karşıtutumlarıüzerine etkinliğini araştırmaktır. Kavram haritaları, öğrencilerin genel kimya laboratuvarıdeneyleri kapsamındaki kavramlarla ilgili kendi aralarında ve araştırmacılarla tartışmalar yapmalarıiçin bir araç olarak kullanılmıştır. Deney grubu öğrencileri (N=41) deneylerini laboratuvar öncesi ve sonrası hazırladıklarıkavram haritalarına dayalıyaptıklarıbireysel, küçük ve büyük grup tartışmalarıyla yürütürken, kontrol grubu öğrencileri (N=43) laboratuvar deneylerini geleneksel yaklaşımlara dayalıgerçekleştirmişlerdir. Kimya laboratuvarına karşıtutum anketi her iki grubun öğrencilerine hem ön ve hem de son test olarak uygulanmıştır. Ankete ait sonuçların istatistiksel analizleri (ANCOVA), öğrencilerin kimya laboratuvarına karşıtutumlarıaçısından deney grubu lehine anlamlıbir farklılık olduğunu göstermiştir. Bu nedenle, laboratuvar öncesi ve sonrasıhazırlanan kavram haritalarına dayalıyapılan tartışmaların, öğrencilerin kimya laboratuvarına karşı pozitif tutum geliştirmede geleneksel laboratuvar öğretiminden daha fazla etkin olduğu sonucuna varılmıştır.
