Abstract

Based on the results of observations at Junior High School (SMP) Muhammadiyah 1 Mlati, it was found that students had difficulty understanding math problems, especially about algebraic material, so that students often made mistakes in solving the questions given, which were shown by achieving low scores and many who got scores below 60. This study aims to improve student learning outcomes in solving algebraic problems with the Snowball Throwing type cooperative learning model. This research is a Classroom Action Research (CAR) with the subject, namely students of class VII D SMP Muhammadiyah 1 Mlati with 32 students. The research object is learning mathematics with the Snowball Throwing type cooperative model. This study uses 3 data collection techniques, namely, observation, tests, and interviews. Observation is used as a guide for researchers in carrying out observation activities carried out to obtain data. The test was conducted to collect data and measure students' ability to solve math problems. Interviews were conducted to determine students' condition in the ongoing implementation of learning and their problems. This study obtained mathematics learning using the cooperative learning model type. Snowball Throwing received positive responses from students because students felt helped in learning mathematics to increase student learning outcomes.

Abstract

Teacher-centered learning may lead to low mathematics learning interest. It can also lead to poor mathematical concept understanding. Therefore, there need to be efforts to improve student motivation and mathematical concept understanding. This research aims at improving the learning motivation and concept understanding in mathematics learning by using Think Pair Share (TPS) learning model. The research is an action research, consisting of 2 cycles. The research setting is Grade XI Fashion 2 class at State Vocational High School (SMK Negeri) 6 Yogyakarta during the even semester of the academic year of 2019/2020 with 32 students. The data collection methods used were observation, interview, questionnaire, and test. The research instruments used were an observation sheet, interview guideline, questionnaire, and test. The instrument validity was also tested in this research. The data analysis used was descriptive qualitative analysis. The research results suggest that mathematics learning through the TPS learning model can improve students' motivation and mathematical concept understanding. The finding is supported by the observation, interview, and questionnaire in every meeting. The improvement of mathematical concept understanding can also be seen from the test result in every cycle. The finding is supported by the average percentage of student learning motivation and concept understanding that show an improvement in every cycle. In cycle, I, the average percentage of student learning motivation from the observation result was 61% and was categorized as Good. In cycle 2, it increased to 78% and was categorized as Good. The average percentage of student learning motivation from the questionnaire in cycle I was 78% and was categorized as Good. In cycle 2, it increased to 83% and was categorized as Very Good. The average percentage of student learning motivation from the cycle test I was 69% and was categorized as Moderate. In cycle 2, it increased to 88% and was categorized as Very Good. Cooperative learning type TPS also got good responses from the students. The finding is supported by the interview result with Grade XI Fashion 2 students at the end of the cycle I and II. Thus, cooperative learning type TPS can improve student motivation and concept understanding.

Abstract

State Junior High School (SMP Negeri) 1 Tempel students in mathematics are still low. Judging from the mathematics scores of Year-End Assessment (PAT) class VIII SMP Negeri 1 Tempel show that as many as 98.40% of students have not reached the minimum completeness criteria (MCC). Based on interviews with students, it was found that learning mathematics was complicated. Students tried to solve math problems but had difficulty solving them. Therefore, the purpose of this study is to determine the problems experienced by students in solving math problems and the factors that cause real challenges, conceptual difficulties, and procedural difficulties in learning mathematics in the function material of class VIII SMP Negeri 1 Tempel in the 2019/2020 school year. This research method is qualitative research. The subjects of this study were 31 students of class VIII A SMP Negeri 1 Tempel. The object of this research is learning difficulties in factual, conceptual, and procedural aspects. Retrieval of data using tests and interviews. The test instrument is in the form of function material questions. Data analysis techniques used the Miles and Huberman model, namely Data Reduction, Data Display, and Data Verification. The results of this study indicate that students have difficulty learning mathematics in terms of functions. Students' problems in the function material obtained 69.25% real difficulties, 63.79% conceptual difficulties, and 61.41% procedural difficulties. Students have a problem in (1) the factual aspect, namely writing the name of the function, writing the set's name, making arrow diagrams, making Cartesian diagrams, and writing the set of consecutive pairs. (2) Students have difficulty defining a function in the conceptual aspect, giving reasons why a relationship can be called a process, distinguishing the origin from the relationship, describing the origin and result area, calculating the number of members of the set, and writing the formulas a function. (3) procedural aspects, students are still lacking in determining the correct and appropriate steps in solving problems. Some students have difficulty determining what steps to take first. Thus resulting in incomplete procedures in solving questions. The factor that causes difficulty in learning mathematics in the function material is students' inaccurate learning patterns. This causes students to forget often and be confused when solving questions.

Abstract

field, students still find it difficult to write symbols or symbols of mathematics, describe problems given in the form of drawings/charts/tables, and turn real problems into the language of mathematics, have not written the conclusions obtained at the end of the problem-solving. The purpose of this study is to improve students' written mathematical communication skills in flat-sided space building materials with a Cooperative Learning Model of Think Talk Write (TTW). The study results using a cooperative learning model type TTW obtained improved mathematical communication skills written on each indicator, i.e., students' ability to express and illustrate problem solutions in the form of images from cycle I amounted to rise to cycle II. The percentage of students' ability to formulate the concept of solving mathematics from problems given by cycle I amount to rise to in cycle II. The percentage of students' ability to express and illustrate problems in mathematical equations in cycle I amount to , rise to in cycle II. The percentage of students' ability to use the language of mathematics and symbols precisely to solve given from cycle I amount to  rise to cycle II. The percentage of students' ability to explain the solving measures in writing and provide conclusions of the problems obtained from the cyclical I amounted to rise to cycle II.
