Investigation of students probabilistic misconceptions

Mut, Ali İhsan
The purpose of the study was to investigate the students̕ probabilistic misconceptions with respect to grade level, previous instruction on probability and gender. The sample of the study was 885 students from different types of the schools (general high schools, private collages, Anatolian high school, vocational high schools, and elementary schools) and from grade levels (5, 6, 7, 8, 9 and 10). The sample represented a range of students with respect to socio-economic level and cultural background. To collect data for the study Probabilistic Misconception Test (PMT) and a questionnaire were administered. The test consisted of 14 problems from 8 probabilistic misconception types. Its content validity was tested. The data of the study were analyzed by means of SPSS. Each misconception type is investigated with respect to all variables. The results of the study revealed that: (a) The frequencies of all misconception types varied across grade levels. (b) The percentages of students who received instruction on probability in the school were higher than those who did not received instruction in terms of misconceptions on Effect of Sample Size and Time Axis Fallacy. In addition, the other misconception types were more frequent among the students who did not receive a certain instruction on probability than the students who received a certain instruction probability before the study; (c) The frequencies of all misconception types varied across gender.

The purpose of this study was to investigate the effect of gender and grade level on students’ logical thinking abilities. A total of 174 sixth, seventh, and eighth-grade students participated in the study. Test of Logical Thinking (TOLT) was administered to determine students’ reasoning abilities. A two-way multivariate analysis of variance (MANOVA) was conducted to determine the effect of grade level and gender on five reasoning modes. Results revealed a statistically significant effect of grade level...

Korkmaz, Oğuz; Öztekin, Ceren; Department of Secondary Science and Mathematics Education (2005)
This study investigated the 9th grade students' achievement regarding diffusion and osmosis in relation to reasoning ability, prior knowledge and gender. A total of 397 ninth grade students participated in the study. The Test of logical thinking (TOLT) and the Diffusion and Osmosis Diagnostic Test (DODT) were administered to determine students' reasoning ability and achievement in diffusion and osmosis, respectively. DODT results showed that the range of correct answers for the first tier was 41 % to 91%. W...

OKTAY, Özlem; Eryılmaz, Ali (Hacettepe University, 2020-04-01)
The purpose of the study is to develop and analyze a content-based needs assessment survey for physics teachers. With this aim, a Teacher Survey on the Nature of Physics (TSNOP) was developed as a measurement instrument for the study. The TSNOP was used to identify inservice physics teachers' needs, wishes, expectations and problems for the Nature of Physics (NOP) unit of a Professional Development Program (PDP). A total of 60 inservice physics teachers participated in the study. TSNOP includes four specifi...
