Remediasi Miskonsepsi Siswa melalui Pembelajaran Problem Posing pada Materi Gerak Parabola

This study to determine the effectiveness of remediation of student misconceptions in a projectile motion of matter through the learning problem posing. The research method used is a quasi-experimental research design with one group pretest-posttest group design. As many as 23 students of class XI selected by the group intact (intact group) as defined in the study sample. Misconceptions students was measured using a 10 item multiple-choice test questions accompanied by reasons. Percentage of student misconceptions before given remediation by 90,48% and the percentage of student misconceptions given remediation after learning through problem posing of 51,90%, resulting in a decrease in the percentage of students who have misconceptions after remediation by 38,58%. Binomial and McNemar test results showed that significant changes in the conception of the 6 indicators questions and not significant at the 4 indicators questions. Effectiveness of remediation based on the calculation of the proportion of reduction in the number of students who have misconceptions with ∆ S = 0.437 and classified as moderate. Thus, posing the problem of effective learning to remediate student misconceptions in a parabolic motion of matter in class XI of MAN 2 Pontianak. So that the problem posing can be used as an alternative for teachers to improve student misconceptions in physics
