- TESTING THE LEARNING OUTCOMES OF WOOD TECHNOLOGY COURSE
-
Summary
In this study, realization level of learning outcomes is examined within the context of a pilot course. Purpose of this study is to test learning outcomes of the pilot course which are determined by instructor. For this purpose, “Wood Technology” course, which has been taught at Department of Wood Science and Furniture Design and Department of Woodworking Industrial Engineering, is chosen as a pilot course. The course consists of 12 units. Learning outcomes of each unit are prepared by the instructor. To test realization level of learning outcomes, two different questionnaire were prepared and applied to students who had taken the course in the period when study was conducted. One of the questionnaire was to determine „students’ expectation“ from each course unit before teaching. The other questionnaire was to determine „achieved level“ at the end of each course unit. To check the validity of achieved level, a quiz was given at the end of each course unit. In addition, another questionnaire was applied to determine level of „achieved learning outcomes“ of graduated students. All data were analyzed statistically and results were compared by t tests. As a result of statistical analyses, it was determined that students underestimated their learning outcomes by 105 %; i.e.; they learned two times more than their expectation. In general, it can be concluded that determination and testing learning outcomes in a course is necessary in order to achieve a better learning-teaching balance.

- EVALUATION OF VARIOUS LIGHTWEIGHT ARMCHAIRS IN TERMS OF ERGONOMICS
-
Summary
This study aimed to evaluate comfort level of the lightweight armchairs based on user’s feedback. For this purpose, 5 different lightweight armchairs were selected and a total of 30 healthy adult volunteers (15 males and 15 female) joined to the study. A survey composed of 10 questions based on three times interval that consist of 5, 15, and 30 minutes was applied to the volunteers. The survey concentrated to obtain subject’s feedbacks related to their body reactions while they are sitting on the armchairs by five point Likert Scale. Results were analysed statistically and according to the results, some of design criteria such as backrest form, armrest height, sitting depth, and sitting height significantly affected the comfort feeling while sitting on sample armchairs. As a conclusion, it can be said that comfort in use can be increased by consideration of ergonomic criteria in design process.

- COMPATIBILITY OF HIGH SCHOOL DESK DIMENSIONS WITH ANTRHROPOMETRIC MEASUREMENTS
-
Summary
The aim of this study was to examine whether school desk dimensions’ match high school students’ anthropometry. Anthropometric variables (shoulder, elbow, knee and popliteal height, buttock-popliteal length and hip breadth) were measured from randomly selected 328 students who attend public high schools in Mugla/Turkey and school desk dimensions which are in use in corresponding schools were measured to match with anthropometric data. The age range of the children was from 14 to 18 years. Mean, median, standard deviations, minimum values, maximum values, were analyzed statistically. The measured anthropometric dimensions of the students were also compared with those of the school desks in use. The results of the study showed that most of the anthropometric data of students differ significantly and there exists a high mismatch between anthropometric measurements and the school desk that they use.
