This study makes an important contribution to an expanding body of international comparative studies by exploring factors predicting differences in science and mathematics achievement by students in Turkey and the Republic of Korea on the 2011 TIMSS assessment. While these countries are similar with regards to population size, cultural beliefs about education, and public expenditure on education, students in each country have different levels of achievement in science and mathematics. The current research investigated how aptitude, instruction, and environment related factors predict Turkish and Korean students' achievement in science and mathematics. In both countries, some factors, such as student aptitude (e.g., science self-efficacy) and environmental (e.g., parental educational level) factors significantly predicted students' science and mathematics achievement. However, we found some differences between the two countries regarding certain classroom environmental variables, such as bullying and student sense of belonging at school. We discuss educational implications for these findings.
Lower reading and mathematics performance of Turkish immigrant students as compared to mainstream European students could reflect differential learning outcomes, differential socioeconomic backgrounds of the groups, differential mainstream language proficiency, and/or test bias. Using PISA reading and mathematics scores of these groups, we examined the role of bias and various measures related to immigrant integration policies of the host societies. Results of a multilevel analysis of reading and mathematics tests demonstrated that at individual level, students with higher scores on an index of economic, social, and cultural status obtained higher achievement scores. At country level, MIPEX scores of education and the human development index of participating countries could predict differences in reading results but not in mathematics. After correction for background characteristics, effect sizes showed a difference of .65 SD (down from a value of .96 before correction) for reading and .58 SD (down from .78) for mathematics. However, a similar correction for background variables increased the score differences between Turkish immigrants and mainstreamers.
ÖzBu çalışmada TIMSS 2015 uygulamasında ele alınan öğrenci, öğretmen ve okul faktörlerinin Türkiye'deki sekizinci sınıf öğrencilerinin matematik başarıları ile nasıl bir ilişki içinde olduğunun araştırılması amaçlanmıştır. İlişkisel tarama modeline göre tasarlanan araştırmanın çalışma grubunu, Uluslararası Matematik ve Fen Eğilimleri Araştırması 2015 uygulamasına katılan 6079 öğrenci ve 220 öğretmen oluşturmuştur. Araştırmanın veri toplama araçları, TIMSS 2015 uygulamasında elde edilen öğrenci ve öğretmen anketleri ile matematik başarı testinden oluşmaktadır. Verilerin analizinde, matematik başarı puanları bağımlı değişken; öğrenci ve öğretmen özellikleri değişkenleri bağımsız değişken olacak şekilde hiyerarşik regresyon analizi yöntemi kullanılmıştır. Araştırmadan elde edilen bulgulara göre, öğrenci ile ilgili değişkenlerin TIMSS 2015'teki matematik başarısındaki farklılıkların %34'ünü açıkladığı görülmüştür. Duyuşsal alan boyutunda yer alan öz-yeterlik inancı 8.sınıf öğrencilerinin TIMSS 2015'te matematik başarılarını yordamada en önemli değişkendir. Öz-yeterlik inancından sonra matematik başarısını yordamada diğer bir önemli değişken öğrencilerin evde sahip oldukları eğitimsel kaynakları olmuştur. Duyuşsal alan içerisinde yer alan tutum ile matematik başarısı arasında negatif yönde bir ilişki bulunmuştur. Matematiğe verilen önem ile öğrencilerin matematik başarıları arasında ise anlamlı bir ilişki çıkmamıştır. Araştırmada okul algısı boyutu altında ele alınan zorbalık, okula aidiyet ve öğretim etkinlikleri ile matematik başarısı arasında anlamlı bir ilişki olup bu ilişki göreli olarak matematik başarısını yordamada daha az öneme sahiptir. Öğrenmede çevre faktörü altında ele alınan okulda başarıya verilen önem, güvenli ve düzenli okul ortamı, okul koşulları, iş tatmini, öğretmenin karşılaştığı sorunlar ve öğrencilerden kaynaklı sorunların hepsi bir araya geldiğinde okullardaki 8. sınıflar arası başarı farkının %29'unu açıklamaktadır. Öğrenmede çevre faktöründe yer alan okulda başarıya verilen önem ve öğrencilerden kaynaklı sorunlar öğrencilerin matematik başarısını yordamada iki önemli değişken olmuştur.Anahtar Kelimeler: TIMSS, matematik başarısı, duyuşsal alan, çevresel faktör, öğretmen AbstractIn the study, it is aimed to investigate the student, teacher and school factors predicting mathematics achievement of Turkish 8th grade students in TIMSS 2015. The group of the study consists of 6079 students and 220 teachers who attended TIMSS from Turkey. The data of the study was obtained from student and teacher questionnaires and mathematics cognitive test scores. In the data analysis, multilevel regression analysis was used in which dependent variables were plausible mathematics scores and independent variables were student, teacher and school scale scores. According to results, 34% percent of student-level variance was explained by student-level variables. It was found that self-confidence level of students was the most important predictor of mathematics achievement among student-level variables. Additionally,...
Perfectionism is a crucial concept in psychology as perfectionism has been found to be related to many important factors affecting daily and academic life. Many researchers have tried to measure perfectionism since 1980. Following an extensive literature review, Smith, Saklofske, Stoeber, and Sherry developed a new perfectionism scale called Big Three Perfectionism Scale (BTPS). The present study addressed the validation study of the BTPS in Turkish sample. The factor structure of the BTPS and measurement invariance across gender groups was tested with the Turkish sample. The BTPS was administered to 609 undergraduate students studying in different departments. Reliability analyses showed that the Turkish version of the scale had an excellent internal consistency. Data from Turkey demonstrated acceptable fit to the three-factor, 10-facet structure of BTPS. The results also indicated that there was no significant difference between fit indexes of configural, metric, and scalar invariance across gender.
