THE EFFECTS OF THE MODEL BASED ACTIVITIES ON OVERCOMING THE MISCONCEPTIONS REGARDING THE PARTICULATE NATURED STRUCTURE OF THE MATTER

Abstract

The purpose of this study is to determine the success levels of the students in terms of the particulate natured structure of the matter and to study the effects of the model based activities on overcoming their misconceptions in this regard. The study is a comparative, quantitative and a retrospective work as well. In the study, screening and single group pre-test and post-test methods were utilized. In addition, the population of the survey group in the study is comprised of 278 primary school students while the population of the experiment group includes 166 primary school students selected from survey group as well. The total population is comprised of the total number of the students in 4th–8th grade in the second period of the 2009-2010 academic year. The data was obtained by the Conceptual Test `The Particle Based Structure of the Matter` (CT-PBSM α=.86). The CT-PBSM was implemented to the experiment group as the post-test then after commencing the with model based activity oriented teaching season. The assumptions of the study were tested by using SPSS 10.0 software through the Paired Sample t-Test, Independent Sample t-Test and One Way ANOVA analysis. The forecasted statistical results were presented by being supplemented by the results of the descriptive analyses. As the conclusion, it was revealed that the model based activities were successful on overcoming the misconceptions in students regarding the particulate natured structure of the matter.

MADDENİN PARÇACIKLI YAPISI İLE İLGİLİ KAVRAM YANILGILARININ GİDERİLMESİNDE MODELE DAYALI AKTİVİTELERİN ETKİSİ

Öz

Bu çalışmanın amacı, ilköğretim öğrencilerinin maddenin parçacıklı yapısı ile ilgili başarı düzeylerini belirlemek ve bu konudaki kavram yanılgılarını gidermede, modele dayalı aktivitelerin etkisini araştırmaktır. Çalışma, karşılaştırmalı nicel geriye dönük bir araştırmadır. Çalışmada tarama modeli ve tek grup öntest- sontest modeli kullanılmıştır. Araştırmanın tarama grubunun örneklemini 278 ilköğretim öğrencisi, deney grubunun örneklemini tarama grubu içerisinden seçilen 166 ilköğretim öğrencisi oluşturmaktadır. Evreni, araştırmanın yapıldığı 2009-2010 eğitim öğretim yılının ikinci döneminde 4.-8. sınıflarındaki toplam öğrenciler oluşturmaktadır. Veriler, Maddenin Parçacıklı Yapısı Kavram Testi (MPYKT, α =.86) ile toplanmıştır. Deney grubuna modele dayalı aktivitelere dayanan ders anlatımı yapıldıktan sonra MPYKT son test olarak uygulanmıştır. Araştırmanın hipotezleri, SPSS 10.0 programı kullanılarak İlişkili Örneklem t-Testi, İlişkisiz Örneklem t-Testi ve tek faktörlü varyans analizi ile test edilmiştir. Kestirel istatistik sonuçları, betimsel analiz sonuçları ile de desteklenerek sunulmuştur. Sonuç olarak öğrencilerde maddenin parçacıklı yapısı ile ilgili var olan kavram yanılgılarının giderilmesinde, modele dayalı aktivitelerin başarılı olduğu görülmüştür.
