UYARLANABİLİR EĞİTSEL İÇERİKLİ WEB ORTAMLARININ TASARIM İLKELERİ: ÖĞRENEN MODELİ

Uyarlanabilir cevrimici ogrenme ortamlarinda ogrenen modeline yonelik tasarim ilkelerinin belirlendigi calisma, karma yontemli karsilastirmali turden iliskisel tarama modeli deseninde tasarlanmistir. Ilkelerinin belirlenme sureci, bagil onemlilik ve bulgularin saglamligi olmak uzere iki boyutta gerceklestirilmistir. Ilkelerin gelistirilmesi ve ilkelere yonelik bagil onemliligin belirlenmesi amaciyla yapilandirilmis cevrimici Delphi yonteminde faydalanilmistir. Elde edilen ilkelere yonelik bulgularin saglamliginin belirlenmesi amaciyla, alanyazin taramasi sonucu elde edilen arastirma verilerinin cozumlenmesinde icerik analizi ile birlikte bulgularin saglamligi degerlendirme olcutleri kullanilmistir. Geleneksel Delphi calismasina kiyasla onceden tanimlanmis daha yapilandirilmis bir ilk anket turunu iceren calismada, 90 (%92) uzmanin yanitlari gecerli sayilmis ve bu uzmanlar calisma grubunu olusturmustur. Ilkelerin belirlenmesinde aritmetik ortalama, ilk ceyrek kayma, standart sapmadan yararlanilan calismanin ilk turunda uzmanlarca 17 ilke belirlenmis, 15 ilke uzerinde uzmanlarin uzlasiya ulasmalariyla dort tur uygulanan Delphi yontemi son bulmustur. Ayrica, uygulama sonucunda elde edilen ilkelerin tamamina yonelik, guvenilirlik analizi (Croanbach Alpha) ve sinif-ici korelasyon katsayisi (ICC) degerleri hesaplanmistir. Delphi yontemiyle belirlenen ilkeler dogrultusunda, ogrenen modelleye iliskin 480 arastirma icerik analizi ile cozumlenmis ve bulgularin saglamligi olcutlerine gore kategorik degerlendirme yapilmistir. Calisma sonucunda uzmanlarin bagil onemlilik olcutlerine gore, 13 ilkede neredeyse mukemmel uzlasma ve 2 ilkede ise onemli derecede uzlasma saglandigi belirlenmistir. Bulgularin saglamligi degerlendirme olcutlerine gore yapilan kategorik degerlendirme sonucunda ise, 14 ilkede guclu arastirma destegi ve 1 ilkede ise orta dereceli (yeterli) arastirma destegi saglandigi belirlenmistir. Ayrica, calisma sonucunda elde edilen gozlemciler arasi uyumunun (ICC=.926) yuksek duzeyde oldugu sonucuna ulasilmistir. Calismada elde edilen ilkeler gerek alanyazin gerekse alan uzmanlarinin ortak egilimlerini gostermektedir.

The Impact of Whatsapp Use on Success in Education Process

The purpose of this study is to explore the effects of WhatsApp use for education and determine the opinions of students towards the process. The study was designed in mixed research model which combines both qualitative and quantitative data. In the quantitative aspect of the study, quasi-experimental design, with a pretest-posttest control group, was used and the data were analyzed by two factor variance analysis for mixed measurements. The analysis indicated that both learning environments have different effects on the success of students and that supporting the traditional environment by using WhatsApp is more effective for the increase of success. For the qualitative aspect of the study, content analysis techniques were employed to analyze the data which were collected by open-ended question forms. The analysis showed that students developed positive opinions towards the use of WhatsApp in their courses. They demanded the same practice in their other courses as well. They reported that learning could also take place unconsciously and the messages with images were more effective for their learning. However, a few students have expressed adverse opinions about the timing of some posts and the redundant posts within the group. Finally, it is suggested that use of WhatsApp in education process be encouraged as a supportive technology.
