This correlational survey study aimed to investigate whether the Turkish prep-class students' foreign language classroom anxiety levels and foreign language achievement significantly differ in terms of such variables as their gender, their experience abroad, perceived level of income and any third language (other than Turkish and English) they knew. Moreover, the study also tried to identify whether the sub-dimensions of the foreign language classroom anxiety scalespeaking anxiety in language class, interest towards language class and anxiety of talking with native speakersignificantly differ in terms of the independent variables afore-mentioned. And the last aim of the study was to understand whether there is any significant correlation between the foreign language classroom anxiety and foreign language achievement. The participants of the study was consisted of 683 students who, having been registered to study at various engineering departments of Fırat University, were receiving compulsory English preparatory education at the School of Foreign Languages during the academic year of 2013-2014. In order to measure the students' foreign language classroom anxiety, the scale developed by Horwitz, Horwitz& Cope (1986) and adapted into Turkish by Gürsu (2011) was used. The grades of the students were taken from the School of Foreign Languages. For data analysis, such statistical tests as percentage, frequency, t-test, ANOVA, eta-squared and Pearson's Correlation were employed. As a result, it was understood that there is a negative correlation between foreign language classroom anxiety and foreign language achievement.

This study was carried out in order to identify to what extent the Turkish students' English classroom anxiety affects their academic achievement in English language. In this quantitative descriptive study, a correlational survey model was employed, and the convenience sampling was done. In order to collect data, the Foreign Language Classroom Anxiety Scale developed by Horwitz, Horwitz and Cope (1986) was used. The latest validity-reliability of this scale was conducted by Gürsu (2011), in which the three-factor structure of the scale was confirmed. The test-retest correlation of the scale was found as .85. This study was conducted with 271 university engineering students receiving compulsory prep-class education at Fırat University during the academic year of 2012-2013. The data of the study were analyzed with the logistic regression analysis. According to the findings, the foreign language anxiety at the beginning of the prep-class education was not effective as the predictor of the academic achievement. On the other hand, it was observed that the students' anxiety, at the end of the education, accounted for the academic failure with its speaking anxiety in language class dimension, and predicted academic achievement with its interest towards language class dimension. This study revealed that the students' anxiety evolving and ever-increasing during their English prep-education powerfully predicted their academic performance. Whatever its source may be, anxiety in learning environments is mostly an unwanted situation. Therefore, it has always been underlined in the literature that in order to facilitate learners' language learning process, the effect of anxiety should be minimized.

Bu araştırmanın amacı Plickers uygulamasının ortaokul beşinci sınıf matematik öğrencilerinin matematik kaygısına ve matematik dersi başarılarına etkisini incelemektir. Araştırmada nicel araştırma yöntemlerinden eşitlenmemiş ön test -son test kontrol gruplu yarı deneysel desenden yararlanılmıştır. Araştırmanın çalışma grubunu 2017-2018 Eğitim öğretim yılında Diyarbakır'da bir ortaokulun üç farklı beşinci sınıf şubesinde öğrenim gören 72 öğrenci oluşturmaktadır. Araştırma grubu, bir deney iki kontrol grubu olacak şekilde yapılandırılmıştır ve deney grubunda 3 haftalık Plickers uygulaması yapılmıştır. Veri toplama aracı olarak, Bindak'ın (2005) geliştirdiği matematik kaygı ölçeği ve araştırmacı tarafından hazırlanan, geçerlik ve güvenirlik çalışması yapılan matematik başarı testi kullanılmıştır. Verilerin analizinde Kolmogorov Smirnov, Kruskal Wallis H ve karma desenli ANOVA testlerinden yararlanılmıştır. Araştırma sonucunda Plickers uygulamasının matematik dersi bölme konusunda akademik başarıyı olumlu yönde etkilediği belirlenmiştir. Plickers uygulaması sınıf akademik başarılarını kademeli olarak artırmaktadır. Ancak Plickers uygulamasının matematik kaygısını etkilediğine yönelik bir bulguya rastlanmamıştır. Test öncesi ve sonrasında deney grubunun düşük düzeyde bir kaygı yaşadığı belirlenmiştir.
