    (Cukurova Univ, 2020) Cetin, Nagihan Imer; Timur, Betul
    In this study, it is aimed to determine cognitive structures of middle school students regarding technology concept via word association test. The research is carried out with students from 5th, 6th, 7th and 8th grade (N: 201) of a middle school. The word association test is used to collect the data. The data collected from the word association test are evaluated by using the content analysis method. The concepts obtained from the content analysis are coded separately by two researchers and the average value of interrater reliability is found as 91%. As a result of the analysis of the data; it is seen that middle school students express 1571 different concepts related to the concept of technology. The concepts are divided into categories and a total of 11 categories are identified. The findings of the study show that students perceive technology as communication tool, computer, product and tool. The most remarkable finding is that students' experiences with technological tools in their everyday life are influential on their technology perceptions. As a result, it is determined that students' have limited understanding regarding technology concept.

    (Cukurova Univ, 2019) Timur, Serkan; Dogan, Fatih; Cetin, Nagihan Imer; Timur, Betul; Isik, Ruveyda
    In this study, it is aimed to develop a valid and reliable achievement test for the subject of Cell belonging to the 6th grade Systems in our Body unit within the scope of Science course. The achievement test was prepared as a 25-item multiple-choice test, considering the cell-related objectives in the 6th grade Science curriculum. The pilot study of the test was carried out with 62 students attending 6th grade in 2017-2018 academic year. The comprehensibility and the consistency with the scientific knowledge of the test items were prepared by the opinions of various experts in the field of science education. The item analysis was performed according to the answers of the students in the achievement test, and the discriminant and difficulty indexes were calculated for each item. After the item analysis, 3 items were excluded from the test and a Cell Achievement Test (CAT) consisting of 22 questions was obtained. The mean item difficulty of CAT was 0.652 and the mean discrimination index was 0.507.

    Secondary School Students' Key Concepts and Drawings about the Concept of Environment
    (Kamla-Raj Enterprises, 2013) Yilmaz, Sirin; Timur, Serkan; Timur, Betul
    The purpose of the present study is to determine the elementary school secondary level students' environment-related key concepts and drawings. The study was carried out with 171 (88 females, 83 males) students from three different schools in the city of Sakarya in 2012-2013 school year. Out of the participants, 35 were fifth grade students, 40 were sixth grade students, 54 were seventh grade students and 42 were eighth grade students. Though the study was a qualitative one, open-ended questions developed by the researchers were used to collect data and content analysis was employed for the analysis of the data. The analyses revealed that the most commonly used environment-related concepts are tree, flower, and forest. When the students' drawings were analyzed, they were grouped under four main headings as Model 1, the environment as a place where animals/plants live-a natural place; Model 2, the environment as a place that supports life; Model 3, the environment as a place impacted or modified by human activity; and Model 4, the environment as a place where animals, plants, and humans live. Among these, the most frequently encountered one in the students' drawings was Model 3, the environment as a place impacted or modified by human activity. Moreover, the students' drawings were also analyzed in relation to gender variable, and it was found that the drawings of female students exhibit more variety than the drawings of the male students. In light of the findings of the study, some suggestions were made for researchers and further research.
