Abstract

The purpose of this study was to determine the relationship between the basic concepts related to the unit of Chemical Reactions and Energy and the sub-concepts underlying for meaningful learning of the unit and to investigate the effectiveness of them on students' learning achievements. For this purpose, the basic concepts of the unit were correlated with the concepts of previous units. The study involved fifty-two 11th grade students who were randomly assigned to the experimental and control groups. Before the instruction, a preparatory course was applied on only experimental group to remedy students' the misconceptions and lack of pre-knowledge identified by the concept test results and the literature reviews. After the preparatory course, the experimental and control groups were taught by the same teacher with the same instruction. The achievement test and interviews results showed that the experimental group significantly had higher scores and fewer misconceptions than the control group.

Özet

Çalışmanın amacı, Kimyasal Reaksiyonlar ve Enerji ünitesinin temel kavramları ile bu ünitenin anlamlı öğrenilmesine temel oluşturan alt kavramlar arasındaki ilişkiyi belirlemek ve öğrencilerin öğrenme başarılarmdaki etkililiğini araştırmaktır. Bu amaçla, ünite ve ilişkili önceki üniteler arasında kavram ilişkilendirmeleri yapılmıştır. Çalışma, rastgele deney ve kontrol grubu olarak ayrılan elli iki 11. sınıf öğrencisiyle gerçekleştirilmiştir. Öğrencilerin, uygulanan kavram testi sonuçlan ve alanyazm incelemelerinden belirlenen önbilgi eksiklikleri ve kavram yanılgılarını giderme amacıyla yalnızca deney grubuyla bir hazırlık dersi yapılmıştır. Hazırlık dersinin ardından, deney ve kontrol grupları aynı öğretmen tarafından aynı öğretimi almışlardır. Başarı testi ve görüşme sonuçları; deney grubunun kontrol grubuna kıyasla daha yüksek puanlar aldığını ve daha az sayıda kavram yanılgısına sahip olduğunu göstermiştir.
