Effect of 5E Instruction Model on Conceptual Understanding Levels: The Factors Influencing Contact Angle

Abstract

This study aimed to develop the activities related to the factors influencing on the contact angle and examine the effect of the instruction based on 5E model conducted with these activities on students' conceptual understanding levels. The activities developed for this aim were applied to 11 students of Balıkesir University Faculty of Medicine who took the Elective Nanoscience and Nanotechnology course. As data collection tools, the Contact Angle Conceptual Understanding Test (CACUT), which consists of 2 open-ended questions about the contact angle and the factors affecting the contact angle, and the written opinions of the groups about the instruction in the evaluation step of 5E model were used. The answers given by the students in CACUT were grouped according to Full Comprehension (FC), Partial Comprehension, Misunderstanding (M) and Not Understanding (U) levels and compared in terms of pre- and post-tests. It was observed in the comparison that the answers in MU level were eliminated and those in FCU increased. In addition, it was observed that there were still students who thought only adhesion or only cohesion forces in the post-test while explaining the factors affecting the contact angle. The students stated positive opinions about the instruction. Suggestions were made to improve the instruction and the activities.

5E Öğretim Modelinin Kavramsal Anlama Düzeylerine Etkisi: Temas Açısını Etkileyen Faktörler

Abstract

Bu çalışmanın amacı, temas açısını etkileyen faktörlerle ilgili olarak etkinlikler geliştirmek ve bu etkinliklerle 5E modeline uygun olarak yapılan öğretimin öğrencilerin kavramsal anlama düzeylerine etkisini incelemektir. Bu doğrultuda geliştirilen etkinlikler Seçmeli Nanobilim ve Nanoteknoloji dersini alan 11 Balıkesir Üniversitesi Tıp Fakültesi öğrencisine uygulanmıştır. Veri toplama araçları olarak, temas açısı ve temas açısını etkileyen faktörlerle ilgili 2 açık uçlu sorudan oluşan Temas Açısı Kavramsal Anlama Testi (TAKAT) ile 5E modelinin değerlendirme basamağında öğretim sürecine yönelik gruplardan alınan yazılı görüşler kullanılmıştır. TAKAT’da öğrencilerin verdikleri cevaplar Tam Anlama (TA), Kısmi Anlama, Yanlış Kavrama (YK) ve Anlamama düzeylerine göre gruplandırılarak, ön ve son testler açısından karşılaştırılmıştır. Karşılaştırmada YK düzeyindeki cevapların giderildiği ve TA düzeyindeki cevapların arttığı görülmüştür. Bunun yanı sıra, temas açısına etkileyen faktörleri açıklarken son testte hala sadece adezyon ya da sadece kohezyon kuvvetlerini düşünen öğrencilerin olduğu görülmüştür. Öğrenciler öğretim süreciyle ilgili olumlu görüş belirtmişlerdir. Uygulanan etkinliklerin ve öğretimin geliştirilmesine yönelik önerilerde bulunulmuştur.
