The purpose of the act class is research what if apply cooperative model from type of Teamn Games Tournament (TGT) that could increase teh Interactive stude from disciples. This research that used descriptive kuantitative method with collecting result from observatio, kuesioner and documentary. The result from research show that score average for whole of indicator that take from disciples beside siklus 1 is 74,7 with passive criteria that 3 people, and the active criteria most active is 14 people. The persentage that reach from first siclus is 72,5 ℅. For applying from the second siclus, that reach from the disciples with the active of criteria that 13 people, and the most active that 21 people. Average score that reach for all disciples that 82,7%. For the active percentage study as the indicator is 87,9℅. From. The observation result and kuetioner that done, the learning with TGT Model for increase the stude active for this research, that reach increasing with amount of the active of disciples and most active for Siclus 1 for Siclus from 31 people become 34 people.

Abstract

The aim of this study is to improve students' problem-solving abilities by using the Reciprocal Teaching instructional style. The study included 28 students from class XI IPS 3 at SMA Negeri 14 Medan as participants. The study centred around the subject of Arithmetic Series. First, a preliminary aptitude exam is given, and at the end of each cycle, a problem-solving aptitude test is given. After analysing the first ability test data, it was found that 18 out of 28 students, or 21%, achieved learning completion. The mean score for the test was 26.7. Following the implementation of the Reciprocal Teaching Cooperative learning model, the data analysis findings for cycle I revealed that 13 out of 28 students, equivalent to 61%, achieved learning mastery. The mean score of the class was 70.7. After cycle II, the data analysis showed that 24 out of 28 pupils, or 86%, acquired full learning. The mean score of the class was 90.86. There is an increase in the mathematical problem-solving abilities of students from cycle I to cycle II. Thus, it can be deduced that introducing the Reciprocal Teaching cooperative learning model in class XI IPS 3 at Medan State High School can improve students' aptitude in solving mathematical issues.

Abstract

The aim of this research is to improve students' mathematics learning outcomes through the problem-based learning (PBL) model using Curipod media. The research subjects consisted of 31 students of class XI TKR 4 at SMK Negeri 2 Medan, with data concentration measurement material. This type of research is classroom action research (PTK), which is carried out in two cycles, each cycle consisting of four stages: planning, implementation, observation and reflection. Based on the results of mathematics learning in the pre-cycle, it was found that only 8 out of 31 students or 25.8% achieved learning completeness, with a class average of 61.74. After implementing the PBL learning model using Curipod media in cycle I, the number of students who achieved learning mastery increased to 23 out of 31 students or 74.2%, with a class average of 76.68. At the end of cycle II, the number of students who achieved learning completion increased again to 28 out of 31 students or 90.3%, with a class average of 84.87. This shows an increase in student mathematics learning outcomes from pre-cycle to cycle II. Thus, it can be concluded that the application of the problem-based learning (PBL) model using Curipod media in class XI TKR 4 SMK Negeri 2 Medan can improve students' mathematics learning outcomes.

Abstract

This research is conducted with the intention of enhancing the learning outcomes of students in class XI-TITL 4 at SMA Negeri 2 Medan through the implementation of a problem-based learning methodology. Two cycles of four stages—planning, doing, observing, and reflecting make up the classroom action research methodology. Thirty individuals, all from class XI-TITL 4, were the subjects of this study. Tests, observations, and documentation are the means of data gathering, while descriptive analysis is the tool of choice for data analysis. According to the study's findings, pupils' average mathematics learning outcomes also improved throughout the two cycles, rising from 70.83 to 79.48. Aside from that, cycle I had a completion rate of 57% and cycle II had a completion rate of 87% for student learning. The study that has been conducted suggests that instructional materials that employ a problem-based learning approach can enhance the learning outcomes for students.
