Abstract

The selection of learning models that are less precise can affect student learning success. Learning in SMP N 1 Srandakan is still centered on the teacher so students tend to be passive in class. This study aims to determine whether there are differences in students' mathematics learning outcomes by using the NHT type of cooperative learning models as well as knowing the effectiveness of the NHT type cooperative learning models for student mathematics learning outcomes. The design of this study is Subjects Posttest Only Control Group Design. The population in this study were students of class VIII of SMP N 1 Srandakan Regency of Bantul in the 2015/2015 academic year with a total of 190 students. Samples in this study were taken using a random sampling technique obtained by class VIII D as an experimental class and class VIII E as a control class. Data collection is done by the test method. Testing instruments using the test the validity of the different power tests and reliability tests. Data analysis techniques using analysis prerequisite tests include normality test with Chi-Square formula, homogeneity test with Bartlett test, and hypothesis testing with t-test. Based on calculations with a significant level α = 5% and degrees of freedom 62, it can be concluded that: (1) There are differences in mathematics learning outcomes between students who use the NHT type of cooperative learning models and students who use the direct learning model. This is indicated by the results of the first hypothesis test that  = 2.3802 and  = 1.99897, so > . (2) The NHT type of cooperative learning model is more effective than the direct learning model. This is shown from the results of the second hypothesis test that  = 2.3802 and = 1.6698, so >

Abstract

Learning that does not involve active student participation can influence student activities, especially in mathematics learning using NHT type cooperative learning models. This study aims to determine an increase in the activity of learning mathematics in class VII D students in the even semester of SMP Muhammadiyah 2 Mlati in the 2015/2016 academic year by using the NHT type of cooperative learning model. This research is a Classroom Action Research (CAR). The setting used is class VII D, amounting to 30 students. The research plan is carried out in 3 Cycles and complete in Cycle III. In Cycle I consisted of 1 meeting, Cycle II consisted of 2 meetings, and Cycle III consisted of 1 meeting. Each Cycle uses NHT type cooperative learning models. Data collected by observation, interview and documentation. Analysis of the data used is qualitative descriptive analysis. The results showed that mathematics learning using the NHT type of cooperative learning model could increase the learning activity of students of class VII D even semester of SMP Muhammadiyah 2 Mlati, Sleman Regency Academic Year 2015/2016. This is evident from the increase in student learning activities. In Cycle I, Cycle II and Cycle III that use the NHT type of cooperative learning model experienced an increase in which the first cycle the average percentage of student activity was 37.92% with poor criteria, the average percentage of activeness in cycle II was 52.5% with sufficient criteria and the average percentage of activeness in cycle III is 65.28% with good criteria.

Abstract

Mathematics is one of the science that grow as technology advances. One way to achieve the learning objectives of mathematics learning media is to make an exciting and fun resource in the learning process. The availability of media learning in school is still limited to print media. Teachers have not used multimedia interactive learning lab space, so it is rarely utilized in learning. This research aims to develop research to generate media learning math using adobe flash CS6 in learning mathematics on linear equations in two variables (SPLDV) grade 8 Junior High School. Research development uses the ADDIE model of development through five stages of development: the stage of the analysis, design, development, implementation, and evaluation. The research subject is material expert, media experts, and State Junior High School (SMP Negeri) 1 Kalasan. The instruments used in this is a questionnaire. The data analysis technique was carried out quantitatively and qualitatively to count the score test results of the feasibility study developed media. The research development of interactive multimedia learning-based adobe flash based on the quality of every aspect of the media learning in terms of expert material in categories with a perfect percentage of an average score of 93,33%, in terms of media experts in categories with a significant percentage of an average score of 94,73%, and the response of the students in the category is exciting with a percentage of an average score of 85,84%. Based on the assessment, then interactive multimedia learning-based adobe flash is handy in the learning process.

Abstract

Learning mathematics in class VII of SMP Muhammadiyah 1 Yogyakarta in the 2015/2016 academic year still uses conventional methods that result in students who are less enthusiastic about learning mathematics. The use of inappropriate learning models makes students less familiar with the material explained by the teacher and results in low mathematics learning outcomes. The population in this study were VII grade students of SMP Muhammadiyah 1 Yogyakarta which consisted of 3 classes. Samples of 2 classes with a total of 67 students were taken by random sampling technique for the class obtained VII F as the experimental class A and class VII E as the experimental class B. The research instrument was a test of learning outcomes. Data analysis uses party testing and a one-party t-test. Based on the analysis of the first hypothesis test on mathematics learning outcomes with a significant level of 5% and 65 degrees of freedom obtained by tcount= 8.12> ttable = 1,999, it shows that there are significant differences between mathematics learning outcomes using NHT type cooperative learning models and those using models TPS type of cooperative learning, and the second test with a significant level of 5% and 65 degrees of freedom obtained by tcountt= 8.12> ttable = 1.66 indicates that the cooperative learning model NHT type is more effective than the TPS cooperative learning model in improving mathematics learning outcomes students.

Abstract

Problem-solving abilities of the students who are still limited to things often appear alone. They lack a sense of responsibility for what became the obligations as a student becomes a problem that became the focus of this research. This research aims to improve the ability of problem-solving and developing character of the responsibility of the student. This research is a Classroom Action Research (CAR) implemented in cycles with cycle one consists of 3 meetings. The subject is an odd semester of Class XI IPA B Islamic Senior High School (MA) Ali Masum school year 2017/2018. The data collection techniques are using observation instruments (observation), interviews, and documentation tests. Analytical techniques descriptive data is done by qualitative and quantitative. The results showed that learning mathematics with the MEAs approach to NHT type cooperative learning could improve problem-solving ability. The results of the study are presented as follows: a) the ability to understand the problem increased from 89.69% to 95.20%, b) the ability to plan the problem solving increased 71.46% to 80.21%, c) the ability to carry out procedures increased 61.46% to 71.04% d) the ability to Recheck the results increased 50.00% to 70.42%. One for the character of responsibility, there is an increase that is from 2.26 (Less Good) in cycle I to 3.37 (Very Good) in cycle II.
