    In Turkey, vocational schools are one of the most important educational institutions for breeding well-qualified manpower in higher education level. At present time, the main purpose of these institutions that provide vocational training in accordance with two-year education programs is: to provide the breeding of of well-qualified manpower who may be able to adapt to scientific and technological developments and provide quality production that needed by business life. In the process of training the students of vocational school in accordance with these qualifications, educational partnerships that are established with the collaboration of both university and industry have become very important. In order to substantiate the necassary cooperation in this partnership Marmara University Vocational School of Technical Sciences has started a project. In this project work, within the inclusion of students, industry and academic staff, three surveys have been conducted in order to collect data. The survey applications that have been carried out included, firstly, the thoughts of the vocational school's students about the education provided in Vocational School of Technical Sciences (T.B.M.Y.O); secondly, their thought of the sector's cooperation with vocational schools and the evaluation of the graduates performances. Thirdly, another survey regarding the adequacy of the training fields and the students of the vocational schools was conducted and it's reviews have been addressed. (C) 2010 Elsevier Ltd.

    VERİ MADENCİLİĞİNDE SINIFLANDIRMA ALGORİTMALARININ PERFORMANS DEĞERLENDİRMESİ VE R DİLİ İLE BİR UYGULAMA
    (2019-02-06) ÇINAR, AYŞE; Ayşe ÇINAR
    Sınıflandırma Yöntemi, veri madenciliğinin başlıca yöntemlerinden biri olup, öğrenme algoritmasına dayanır. Büyük ölçekli bir veri içinde gizli kalmış bir örüntüyü keşfetmek amacıyla uygulanır. Veri madenciliği kapsamında, örüntü, bir varlık için dijital ortamda kaydedilmiş; gözlemlenebilir, ölçülebilir ve tekrar edilebilir bir bilgi olarak ifade edilmektedir. Ulaşılmak istenen bilginin elde edilmesi için uygulanan sınıflandırma algoritmaları, içerdiği verinin ortak özelliğine göre veri setinin belirli sınıflara ayrılmasını (ayrıklaştırılmasını) sağlamaktadırlar. Bu işlemin ardından bir sınıflandırma modeli elde edilir. Elde edilen sınıflandırma modeli yeni bir veri seti üzerinde uygulanarak, model ile belirlenmiş olan sınıfların veri seti içindeki benzerlerinin varlığı araştırılır. Söz konusu işlem “örüntü tanıma” olarak isimlendirilmektedir. Bu çalışmada, veri madenciliğinde sınıflandırma süreci ele alınarak, C5.0 ve Gini isimli iki farklı sınıflandırma algoritması ile bir uygulama gerçekleştirilmiştir. Bu amaçla açık kaynak kodlu R dili uygulanarak, her iki sınıflandırma modelinin tahmin değerlerinin doğruluğuyla ilgili performans ölçüm değerleri elde edilmiştir. Ayrıca, en iyi performans ölçüm değerine sahip bir model ele alınarak, sonuçları değerlendirilmiştir

    Machine learning algorithm for grading open-ended physics questions in Turkish
    (SPRINGER, 2020) ÇINAR, AYŞE; Cinar, Ayse; Ince, Elif; Gezer, Murat; Yilmaz, Ozgur
    Worldwide, open-ended questions that require short answers have been used in many exams in fields of science, such as the International Student Assessment Program (PISA), the International Science and Maths Trends Research (TIMSS). However, multiple-choice questions are used for many exams at the national level in Turkey, especially high school and university entrance exams. This study aims to develop an objective and useful automatic scoring model for open-ended questions using machine learning algorithms. Within the scope of this aim, an automated scoring model construction study was conducted on four Physics questions at a University level course with the participation of 246 undergraduate students. The short-answer scoring was handled through an approach that addresses students' answers in Turkish. Model performing machine learning classification techniques such as SVM (Support Vector Machines), Gini, KNN (k-Nearest Neighbors), and Bagging and Boosting were applied after data preprocessing. The score indicated the accuracy, precision and F1-Score of each predictive model of which the AdaBoost.M1 technique had the best performance. In this paper, we report on a short answer grading system in Turkish, based on a machine learning approach using a constructed dataset about a Physics course in Turkish. This study is also the first study in the field of open-ended exam scoring in Turkish.

    Internship education analysis of vocational school students
    (ELSEVIER SCIENCE BV, 2010) ÇINAR, AYŞE; Polat, Zuhal; Uzmanoglu, Selcuk; Isgoren, Nuriye Cevik; Cinar, Ayse; Tektas, Necla; Oral, Bekir; Buyukpehlivan, Gulhan; Ulusman, Leyla; Oznaz, Demet; Uzunboylu, H
    The main purpose of vocational and technical education is to make the individuals gain; knowledge, ability, and practice sufficiency which are needed for particular occupation. On the other hand the main function is to make the individual provide financial income and with this be useful to society at social and economic ways. Vocational and technical education has great affection power at development of country's economy with human labor qualities. For this reason, in the developed countries vocational and technical education has special importance. In the developed countries; for more strong economy and more rapid social development, more qualified work labor is need to be provided. With this purpose, an effort is made to develop vocational and technical education. In Turkey, vocational schools are one of the most important education institutions at raising qualified human power. It is aimed the vocational school students to have more theoretical knowledge than technical man, and more practice ability than engineers by graduating with technician title. The cooperation between university and industry has importance at vocational school graduates having these abilities. In the education programs; students must continue a part of their education at industrial companies for 30 working days duration. This process is named as internship and it is necessary for the students to graduate. Students can find various abilities during the period where they were at the companies. In this study; it is aimed to analyze the expectations from internship education, and the gained knowledge and abilities of Marmara University Vocational School of Technical Sciences students. According to this, an answer is searched to the question What kind of knowledge and abilities do the vocational school students gain during the internship period? The universe of this study is the students studying at Marmara University Vocational School of Technical Sciences programs. It is goaled to discuss the education partnership between vocational school and industry according to the knowledge and abilities the students gained during the internship period.
