WOS: 000456339900004 This study aims to identify secondary school RCE teachers' level of using alternative techniques of measurement and evaluation, to find the encountered problems and to purpose solution suggestions for those problems. The study group consists of 147 RCE teachers who worked in secondary schools of Sivas city center in 2014-2015 academic years. It was aimed to reach 147 teachers, but only 120 teachers could be reached. So, the percentage of reaching the target group is % 81,63. Moreover, we interviewed with 10 teachers who were chosen randomly from the target group. Both quantitative and qualitative data were obtained from the questionnaire which was applied to the teachers. While analyzing the quantitative data, charts were prepared by using percentages and frequency values. At the subsections of charts explanations were written. While analyzing the qualitative data we used descriptive analysis techniques. When we evaluated the results of the study, it was seen that of performance works, projects, observation and concept map techniques were used much more than the rest of the techniques. It was found that teachers' gender, age and the graduated programs dramatically affected their level of using techniques of measurement and evaluation.

Farklı seviyelerde mannan-oligosakkarit (MOS)’in 80 gün süreyle karabalıkta (Clarias gariepinus) büyüme, barsak ve karaciğer histolojisine etkileri incelenmiştir. Çalışmada kontrol yemine (ticari alabalık yemi) ‰1, ‰2 ve ‰3 düzeyinde MOS ilavesi yapılmıştır. Çalışma sonunda canlı ağırlık kazancı, yem değerlendirme oranı, hepatosomatik ve gonadosomatik indeks değerlerinin gruplar arasında istatistiki bir fark göstermediği belirlenmiştir (P>0.05). Benzer bir şekilde MOS ilavesinin barsak ve karaciğer dokularının histolojisinde de bir farklılık yaratmadığı tespit edilmiştir., Different levels of dietary mannan-oligosaccharide (MOS) administered for 80 days to African catfish (Clarias gariepinus) were evaluated for their efficacy on growth parameters, and intestine and liver histology. The following levels of MOS were used in commercial trout diet: 1‰, 2‰ and 3‰ during the trial. At the end of the feeding period the live body weight gain and feed conversion ratio, hepatosomatic and gonadosomatic index values were found similar for all experimental groups (P>0.05). Also, dietary MOS did not significantly affect the liver and intestine histology.
