Öz: Fen öğretim programının vizyonu fen okuryazarı bireyler yetiştirilmesi olarak belirtilmiştir. Fen okuryazarı bireyler bilimsel bilgi ile birlikte bilimsel becerileri de kullanabilen kişilerdir. Öğrencilerin sahip olduğu bilimsel süreç becerilerinin geliştirilmesi bu açıdan önemlidir. Bu çalışma ile de ortaokul öğrencilerinin Kuvvet ve Hareket ünitesi için geliştirilen etkinliklerde bilimsel süreç becerilerini kullanma düzeylerinin karşılaştırılması amaçlanmıştır. Çalışma grubu olarak her bir sınıf düzeyinden 30'ar olmak üzere, ortaokul 5, 6, 7 ve 8. sınıf düzeyinden toplam 120 öğrenci belirlenmiştir. Araştırmacılar tarafından geliştirilen etkinlikler her sınıfta birer ders saati uygulanmış ve öğrencilerin bu etkinliklerde kullandıkları bilimsel süreç becerileri basamakları analiz edilmiştir. Araştırmanın sonucunda farklı sınıf düzeylerinde bilimsel süreç becerileri ile karşılaşılma sıklıklarının değişiklik gösterdiği belirlenmiştir. Gözlem yapma ve önceden kestirme becerilerinin bütün sınıflarda karşılaşılma oranı yüksek iken, verileri yorumlama ve karar verme becerileri ile karşılaşılma oranı daha azdır. Daha üst düzeydeki sınıflarda öğrenim gören öğrencilerde bile karşılaşılma oranı düşen beceriler mevcuttur. Verileri kullanma ve model oluşturma becerisi en fazla 5. sınıf öğrencilerinde karşılaşılmış ve üst düzeydeki sınıflarda karşılaşılma oranı azalmıştır. Bu sonuçlar ışığında araştırmada öğrencilerde karşılaşılma sıklığının az olduğu becerilerin geliştirilmesine yönelik uygulamalar yapılması önerilmektedir.

Science literate individuals are people who can use scientific skills with scientific knowledge. The development of the science process skills that students have is important in this regard. This study also developed activities aimed to compare the levels of science process skills for middle school students in force and motion unit. The working group is determined such as 30 students from each grade for 5. 6. 7. and 8. and a total of 120 students. The activities developed by their searchers applied an hour in each class and science process skills of students used in these activities are analyzed. The result of the study was determined that the scientific process skills vary with frequency encountered in different grade levels. The rate of observing and predicting skills when faced high in all classes, data interpretation and decisionmaking skills with less experienced rate. Students in grade encountered great, even though the rate of falling skills are available. At the light of these results using data and modeling skills up to 5th grade students who met and fell in the face of large class rate. It is recommended that practices can be done for the development of skills in students that encountered low frequency.

This study aims to investigate the effect of guided inquiry-based learning approach on conceptual change and durability of sixth-grade middle school students regarding density concept. In this study, qualitative research methods were used. The study group consisted of 26 students studying in the sixth grade of a state middle school in the western part of Turkey. The data collection tool Test of Conceptual Understanding of Density (TCUD), including three open-ended questions, was used. TCUD was administered to the students in the study group before, immediately after, 6 weeks after and 24 weeks after the instruction. The results showed that the rate of giving scientific answers about the density concept of increased, whereas the rate of misconceptions decreased. It was also determined that the students were able to preserve scientific knowledge 6 and 24 weeks after the instruction, even if it was not the same as after the instruction. The effect of the course content which was prepared by following the guided inquiry-based learning approach on students' conceptual change and durability regarding the concept of density was discussed within the scope of the relevant literature and suggestions were made for further studies. Keywords: Conceptual change, conceptual durability, guided inquiry, middle school students
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
