<![CDATA[Abstract: The purpose of this research is to know the effectiveness of remediation using the model type Numbered Heads Together (NHT) assisted by Student Worksheet (LKS) in overcoming the misconception of students at Regular Straight Motion (GLB) in grade VII SMP Negeri 1 Segedong Regency Pontianak. The form of research design used was pre-experimental design by using the draft of one-group pretest-posttest design. The number of research sample is 30 students. The result of data analysis shows that the average percentage of the reduction in number of students misconception is 55,54% (classified medium). The result of t-test analysis obtained tcount (13,25) > ttable (2,04). This shows that remediation misconception using the model type NHT assisted by LKS is significantly affecting the differences in the ability of students to solve problem. According to Barometer of Hattie, the effectiveness level of the model type NHT assisted by LKS to overcome the misconception of students is classified high in the amount of 3,2.
