In addition, the effect of instruction on students’ attitudes toward science as a school subject and the effect of gender difference on understanding matter concepts were investigated. iv Seventy five, seventh grade students from four classes of a General Science Course taught by the same teacher at Özel ENKA Middle School during fall semester of 2003–2004 was enrolled in this study. The classes were randomly assigned as conrol group and experimental group. Students in the control group received traditional science instruction including traditional lecture method with discussions and traditionally designed labsheets. Students who were in the experimental group received conceptual change instruction accompanied with demonstration and computer assisted concept mapping. Both groups were administered Matter Concept Test as pre- and post-tests and Attitude Scale toward Science as a School Subject. In addition to these, Science Process Skill Test was used at the beginning of the study to determine students’ science process skills. T-test, univariate analysis of variance (ANOVA) and analysis of covariance (ANCOVA) were used for testing the hypotheses of the study. The results indicated that conceptual change instruction accompanied with demonstration and computer assisted concept mapping caused a better acquisition of scientific conceptions related to matter concepts and produced more positive attitudes toward science as a school subject than traditionally designed sicence instruction. In addition, science process skill was a strong predictor in understanding matter concepts. On the other hand, no significant effect of gender difference on students’ understanding of matter concepts and their attitudes toward science as a school subject was found. v Keywords: Misconceptions, Alternative Conceptions, Conceptual Change Approach, Traditional Science Instuctin, Concept Map, Demonstration, Attitude Toward Science as a School Subject, Matter. vi ÖZ GÖSTERI VE BILGISAYAR DESTEKLI KAVRAM HARITALARIYLA DESTEKLENEN KAVRAMSAL DEGISIM METODUNUN ÖGRENCILERIN MADDE KONUSUNU KAVRAMALARINA ETKISI Yavuz, Ayse Doktora, Ortaögretim Fen ve Matematik Alanlari Egitimi Bölümü Tez Yöneticisi: Prof. Dr. Ömer Geban Ocak 2005, 133 sayfa Bu çalismanin temel amaci gösteri ve bilgisayar destekli kavram haritalariyla desteklenen kavramsal degisim metodunun yedinci sinif ögrencilerinin madde konusunu anlamalarina etkisini geleneksel yöntem ile karsilastirmaktir. Ayni zamanda ögretim yönteminin ögrencilerin Fen Bilgisi dersine yönelik tutumlarina etkisi ve cinsiyet farkinin ögrencilerin madde ile ilgili kavramlari anlamalarina etkisi de arastirilmistir. vii Bu çalisma Özel ENKA Ilkögretim Okulu’nda 2003-2004 Egitim Ögretim yili sonbahar döneminde ayni ögretmenin Fen Bilgisi alan dört sinifinda toplam seksen, yedinci sinif ögrencisiyle yapilmistir. Siniflar rastgele olarak kontrol ve deney grubu olarak seçilmistir. Kontrol grubunda geleneksel yönteme dayali anlatim, tartisma ve geleneksel yöntemle hazirlanmis deneyler kullanilmistir. Deney grubunda ise kavramsal degisim yöntemi gösteri deneyleri ve bilgisayar destekli kavram haritalari ile pekistirilmistir. Iki gruba da Madde Kavram Testi öntest ve sontest olarak uygulanmistir. Ögrencilerin Fen Bilgisi dersine karsi tutumlarini belirlemek üzere Fen Bilgisi Tutum Ölçegi uygulanmistir. Bunlara ek olarak çalismaya baslamadan önce ögrencilerin islem becerilerini belirlemek üzere Bilimsel Islem Beceri Testi uygulanmistir. Çalismanin hipotezleri t-testi, tek degiskenli varyans analizi (ANOVA) ve ortak degiskenli varyans analizi (ANCOVA) kullanilarak test edilmistir. Sonuçlar gösteri deneyleri ve bilgisayar destekli kavram haritalariyla pekistirilen kavramsal degisim metodunun ögrencilerin madde kavramlarini anlamalarinda daha etkili oldugunu ve Fen Bilgisi dersine karsi daha olumlu tutuma yol açtigini göstermistir. Ek olarak, Bilimsel islem becerisinin de ögrencilerin madde ile ilgili kavramlari anlamalarina istatistiksel olarak anlamli katkisi oldugunu belirlemistir. Diger taraftan, cinsiyet farki ögrencilerin madde kavramlarini anlamalarinda ve Fen Bilgisi dersine karsi tutumlarinda istatistiksel olarak herhangi bir etki yaratmadigi görülmüstür. viii Anahtar Kelimeler: Kavram Yanilgilari, Alternatif Kavramlar, Kavramsal Degisim Yaklasimi, Geleneksel Yöntem, Kavram Haritasi, Gösteri Deneyi, Fen Bilgisine Karsi Tutum, Bilimsel Islem Becerisi, Madde ix ACKNOWLEDGMENTS I wish to express my deepest gratitude to my supervisor, Prof. Dr. Ömer Geban, for his guidance, advice, criticism and encouragement and insight throughout the research. x
