The Effect of Enriched Learning Environments on the Conceptual Understanding of Students: “The Erosion and Landslide”

The aim of this research is to investigate the effect of enriched learning environments which have been developed in the framework of the “erosion and landslide” concepts on the conceptual understanding of students. A quasi-experimental method has been used in this research. The sample consists of 40 students. 5th grade students (aged 11-12) selected from a primary school in the province of Trabzon in Turkey. To collect data, the researchers used concept test, interview consisting of semi-structured questions and drawing test. When the post test results are examined, a significant difference is identified in favour of the experiment group (U=128,00, p<.05). However, the fact that students were not able to reflect this result to their drawings is striking. In the post drawings made on the concepts of erosion and landslide, the number of students who did not make any drawings in the experiment and control groups is quite high. This result can be stem from student’s operational periods. 5th graders are in the process of transition from the concrete operational period to the abstract operational period. They had problems to reflect their thinking’s to drawings. Ready-made pictures were utilized in the poster assignment used in this research. A poster activity which includes the drawings of students can be carried out in a future research.

Beyin Temelli Öğrenme Yaklaşımına Dayalı Web Destekli Öğretim Materyalinin Etkililiğinin Değerlendirilmesi: Işık ve Ses Ünitesi

Bu arastirmanin amaci, ilkogretim 6. sinif ‘Isik ve Ses’ unitesinde yer alan konularin ogretiminde yararlanilacak beyin temelli ogrenme yaklasimina dayali web destekli ogretim materyali gelistirmek ve materyalin ogrenci akademik basarisi uzerindeki etkililigini degerlendirmektir. Arastirmada yari deneysel yontem kullanilmistir. Calismanin orneklemini, ayni okulun iki ayri subesinin altinci sinifinda ogrenim goren 58 ogrenci olusturmaktadir. Calismanin verileri; “Isik ve Ses” unitesi basari testi ile elde edilmistir. Deney ve kontrol gruplarinin kendi iclerinde karsilastirilmalari bagimli t-testi, kendi aralarindaki karsilastirmalari bagimsiz t-testi ile yapilmistir. Arastirma sonucunda “Isik ve Ses” unitesi kapsaminda hazirlanan ogretim materyalinin deney grubu ogrencilerinin akademik basarilari uzerinde kontrol grubu ile kiyaslandiginda anlamli olcude (t(56)= 2,27; p<.05) etkili oldugu tespit edilmistir.
