Abstract

Until now, Indonesia is still in the category of worrying literacy, which is caused by the low interest in reading among Indonesian people. This is supported by a survey conducted by PISA, where Indonesia's ranking is ranked 64 out of 65 countries. In addition, a survey conducted by UNESCO also supports that the reading interest of Indonesian people is at 0.001, which means that out of 1,000 Indonesian people, only one person has a high interest in reading. This indicator should be a concern and even a warming for the Government, because it is a setback for the country in terms of human resources, especially for students. The method used in this activity is training, where students are trained to read, understand math and science problems that are contextual to life, and try to solve the problems. In addition, students are given motivation to continue to use the library as a fun place to read. Based on the results of data collection through questionnaires and interviews, we found that this activity had a positive influence on students' literacy understanding, especially among Payeti Christian High School students. The expected positive impact of this training is that it can increase students' motivation to read, especially students' understanding in understanding contextual mathematics and science problems so that it can improve students' conceptual understanding abilities well.

Abstract

This study aims to evaluate the effectiveness of the Numbered Head Together (NHT) learning model on the mathematics learning outcomes of grade XI students in the topic of function composition at SMA PGRI Waingapu. This research employed a quantitative approach using an experimental method with a One Group Pretest-Posttest Design. The research sample consisted of 33 randomly selected students from class XI-3. The research instrument included pretest and posttest question as well as a student response questionnaire. Data were analyzed using both descriptive and inferential statistics through a one sample t-test. The pretest result showed a mean score of 31,79 with a standard deviation of 11,826, while the posttest result increased to a mean of 83,73 with a standard deviation of 7,027. A total of 85% of students achieved mastery learning after being taught using the NHT model. The t-test showed a significance value of 0,001 (p<0,05), indicating a statistically significant difference between the posttest mean and the Minimum Mastery Criterion. Furthermore, the proportion test showed a significance value of 0,041, supporting the success of the model in improving student mastery. Student responses to the NHT model were also categorized as positive, with 70% agreement on most aspects. Based on these findings, it is concluded that the NHT model is effective in improving students mathematics learning outcomes.

Abstract

The application of the Numbered Head Together (NHT) type cooperative model with refusi board media at SMP Negeri 1 Umbu Ratu Nggay Tengah aims to improve students' understanding of mathematical concepts. The research method used was Classroom Action Research (PTK) involving 31 students. Research data collection techniques use written test techniques and observation techniques, with data analyzed using descriptive statistical analysis methods. The results showed a significant increase with the percentage of success in pre-cycle students' comprehension ability of 6%, increasing by 23% in cycle I, then increasing to 77% in cycle II. Thus, it can be concluded that the application of the Numbered Head Together (NHT) type cooperative learning model with refusi board media can improve students' understanding of mathematical concepts.
