ÖzBu çalışmanın amacı geçerlilik ve güvenilirlik çalışmalarının yapıldığı bir enformatik dersi başarı testi geliştirmektir. İlk olarak, 25 alt konuya, her birine 2 katı soru olacak şekilde, bir içerik ağacında 80 çoktan seçmeli soru belirlenmiştir. 8 uzmana sorular sorulmuş ve sorular ve soruların ait olduğu birimler üzerinde kapsam geçerlilik indeksi hesaplanmıştır. Test için hesaplanan kapsam geçerlilik endeksi 0,91'dir. Başarı testi 21 BÖTE 3. sınıf öğrencisine uygulanmıştır. TAP programı yardımıyla madde analizi yapılmıştır. Kuder-Richardson-20 Güvenilirlik katsayısı değeri 0,858 olarak hesaplanmıştır. Her alt konuda madde ayırt edicilik ve madde zorluk değerleri uygun olan maddeler belirlenerek toplamda 40 soruluk teste ulaşılmıştır. Elde edilen testte ortalama madde zorluk değeri 0,638 olarak bulunmuştur. Bu durum madde zorluğunun orta düzeyde olduğu anlamına gelmektedir. Ortalama madde ayırt ediciliği 0,444 olarak bulunmuştur. Bu değer madde ayırt edicilik özelliğinin çok iyi düzeyde olduğu anlamına gelmektedir. 40 çoktan seçmeli soruya indirgenmiş geçerlilik ve güvenilirlik süreçleri yapıldığı için, test güvenilir ve geçerlidir, farklı enformatik dersleri için bir başarı testi olarak kullanılabilir. AbstractThe purpose of this study is to develop an Informatics course achievement test that validity and reliability studies have been carried out. First, 80 multiple choice questions were determined in a content tree, which is 2 times for each sub-subject(n=25). Questions were asked to 8 experts and the content validity index was calculated on the questions and the units to which the questions belong. The content validity index calculated for the test was 0.91. The achievement test was applied to 21 CEIT 3rd-grade students. Item analysis was carried out with the help of the TAP program. Kuder-Richardson-20 Reliability coefficient value was calculated as 0.858. In each sub-item, item discrimination and item difficulty values were determined and a total of 40 questions were reached as a result. In the obtained test, the mean item difficulty value was found to be 0.638. This means that the item difficulty is average. The mean item discrimination was found to be 0.444. This value means that the item discrimi-nation is very good. Since the validity and reliability pro-cesses reduced to 40 multiple-choice questions have been conducted, the test is reliable and valid can be used as an achievement test for different informatics courses.
One of the most emphasized skills for social, educational and workplace settings is creativity in the present decade. This study aims to understand whether a collaborative digital storytelling production project improves the creativity of undergraduate students. 109 students engaged in group work and employed a range of digital tools (i.e. wikis, storyboard creation tools, video editing programs) for creating digital stories about the 21stcentury problems they think relevant. Students were able to review and comment on each other’s scenarios and pres ent their digital stories to their classmates at the end of the project. The adapted version of ‘How Creative Are You?’ scale (Whetten & Cameron, 2011) was used for measuring the students’ creativity scores before and after the implementation. Whereas resu lts indicated that creativity scores were increased by the digital storytelling production project, this effect was not significant. However, observation of the production process revealed some components of creative thinking skills of students.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
