                            <p>Extracurricular activities are those that fall outside the formal curriculum, performed by students. Literature offers extracurricular activity as one of the factors affecting academic achievement. This study aims to determine the effects of students&#039; participation in extracurricular activities on their academic achievements by using PISA-2015 data. Secondary data were used for analysis. The population of the study consists of the data of 519334 students evaluated in PISA-2015. No samples are set as determined population is completely accessible. A four-step secondary data analysis guide was used in the analysis of data. Independent samples t-test was used to analyze the data. The results have proved that the average mathematics, reading skills and science scores of students who participated in extracurricular activities are lower than those who did not participated in extracurricular activities. There is a statistically significant difference between the means in favor of students who did not participated in extracurricular activities. Another remarkable finding of the study is that the effect of participation in extracurricular activities on successful and unsuccessful students varies. The average mathematics, reading skills and science scores of the successful students who participated in extracurricular activities are higher than successful students who did not participated in extracurricular activities. In the case of unsuccessful students, the opposite situation exists. The average mathematics, reading skills and science scores of the unsuccessful students who participated in extracurricular activities are lower than unsuccessful students who did not participated in extracurricular activities. In this study, it is concluded that extracurricular activities may have negative effects on academic performance of unsuccessful students. Findings are in line with the literature and further recommendations were given in the study.</p></trans-abstract>

İlgili alanyazına göre ders dışı etkinliklere katılım, akademik başarıyı etkileyen faktörlerden biridir. Bu çalışma, PISA-2015 verilerini kullanarak öğrencilerin ders dışı etkinliklere katılımının akademik başarılarına etkisini belirlemeyi amaçlamaktadır. Bu çalışmada analiz için ikincil verilerden yararlanılmıştır. PISA-2015’de değerlendirmeye alınan 519334 öğrenciye ait veriler araştırmanın evrenini oluşturmaktadır. Tespit edilen evrenin tamamına ulaşıldığından ayrıca örneklem tayinine gidilmemiştir. Toplanan verilerin incelenmesinde dört adımdan oluşan ikincil verilerin analizi kılavuzu kullanılmıştır. Elde edilen verilerin analizinde bağımsız örneklemler için t-testi kullanılmıştır. Araştırma bulgularına göre, ders dışı etkinliklere katılan öğrencilerin matematik, okuma becerileri ve fen puan ortalamaları, ders dışı etkinliklere katılmayan öğrencilerden düşüktür. Ortalamalar arasında ders dışı etkinliklere katılmayan öğrenciler lehine istatistiksel açıdan anlamlı farklılık vardır. Araştırmanın bir diğer çarpıcı bulgusu ise başarılı ve başarısız öğrencilerde ders dışı etkinliklere katılımın başarıya etkisinin farklılık göstermesidir. Ders dışı etkinliklere katılan başarılı öğrencilerin matematik, okuma becerileri ve fen değerlendirmesinden aldıkları puanların ortalaması, ders dışı etkinliklere katılmayan öğrencilerden yüksektir. Başarısız öğrencilerde ise tam tersi bir durum vardır. Ders dışı etkinliklere katılan başarısız öğrencilerin matematik, okuma becerileri ve fen değerlendirmesinden aldıkları puanların ortalaması, ders dışı etkinliklere katılmayan öğrencilerden düşüktür. Bu araştırmada, ders dışı etkinliklerin özellikle başarısı düşük öğrencilerin akademik performansları üzerinde olumsuz yönde etkiler meydana getirebileceği sonucuna varılmıştır. Sonuçlar, ilgili alanyazınla göreceli olarak uyumludur. Çalışma sonuçlarına dayanarak önerilerde bulunulmuştur.</p></abstract>
