This research is motivated by the low mathematical problem solving ability of students at the Golden Star Informatics Junior High School. This study aims to determine the effect of the Numbered Heads Together (NHT) cooperative learning model on the mathematical problem solving ability of the students of class VIII SMP Informatika Golden Star. The research method used is quasi-experimental with posttest only control design. Class VIII A as the control class and class VIII B as the experimental class. The instrument used to determine the mathematical problem solving ability is the post test results of six questions. Data analysis for students' mathematical problem solving ability was carried out using the t' test. Based on the results of the data analysis of students' mathematical problem solving abilities, the results of hypothesis testing using the t' test were obtained compared to at a significant level of 0.05 Because , it was rejected. This shows that the average mathematical problem solving ability of students from the two groups is not the same. Then there is the effect of the application of the NHT cooperative learning model on the mathematical problem solving abilities of eighth grade students of Golden Star Informatics Junior High School.

This study highlights the effect of (1) training and development, (2) Information and Communication Technology (ICT) skills, and (3) additional employee allowances (Tambahan Perbaikan Penghasilan or TPP) on teacher performance at UPT SMA Negeri I Palopo. This is a quantitative study in an ex post facto correlational design. The population includes the 60 entire teachers at UPT SMA Negeri 1 in Palopo City, from which a sample size is calculated using Slovin’s formula at a 5% confidence level. Instrument of data collection fits in a 5-scale Thurstone questionnaire that measures four variables, i.e., training and development(X1), ICT skills (X2), additional employee allowances(X3), and teacher performance (Y). SPSS 23 is used to run multiple regression for data analysis. Findings indicate that the partialeffect of X variables on teacher performance at UPT SMA Negeri 1 Palopo is 25,7% (training and development-X1), 43,1% (ICT skills-X2), and38,2% (additional employee allowances-X3). In terms of simultaneity, the influence of X variables on teacher performance is 45%. These findings suggest that the constructs of training and development, ICT skills, and additional employee allowance, both partially and simultaneously, are helpful for aiding in the improvement model of teacher performance. UPT SMA Negeri 1 Palopo can use these findings to define performance quality plan for its entire teacher workforce.
