The population in this study were students of class VIII SMP Negeri 33 Buton Tengah, which consisted of 1 class of 24 students. The instruments used in this study were achievement tests and interviews. The research results obtained were the types of errors made by students when solving word problems on a system of two-variable linear equations based on Newman's criteria, for students who made the fewest mistakes including: errors in understanding the problem, transformation errors, and errors in writing answers. For students who are making mistakes include: misunderstanding the problem, transformation errors, process skills errors, and answer writing errors. For students who make the most mistakes include: reading errors, understanding problem errors, transformation errors, process skill errors, and answer writing errors. The causes of reading errors include students not being able to interpret the meaning of each word in the problem correctly. what is known and asked and lack of understanding of the meaning of the question transformation error includes students not writing down the mathematical model of the problem and not being able to make an appropriate mathematical model process skills error includes students who are less skilled in performing calculations and do not carry out the completion process correctly answer writing errors include no make conclusions, do not precisely determine and write down the final results of the settlement.

The aim of this research is to find out the differences in student achievement who are taught by using the Problem Solving method and the Conceptual Understanding Procedures (CUPs) method for the seventh grade students of SMPN 14 Buton Tengah. This research is a quantitative quasi-experimental method. The population of this study were all seventh grade students of SMP Negeri 14 Buton Tengah for the academic year 2021/2022 which consisted of two classes, namely 46 students. The sampling technique used was saturated sampling technique, where all members of the population were used as samples. The data collection in this research is the giving of students’ mathematics achievement tests to both classes after all learning subjects are completed, with problem solving methods and Conceptual Understanding Procedures (CUPs) methods. The data analysis technique in this study used descriptive statistics and inferential statistics. The results of the descriptive analysis of the mathematics learning achievement of the experimental class I students obtained an average value of 83.91 and the average mathematics learning achievement of the experimental class II students was 75.43. Data processing in inferential statistics with t-test obtained the value of tcount = 2.120 with df = 44 sig. (2-tailed) at 0.040 < (0.05) so that it can be concluded that there is a significant difference between the mathematics learning achievement of students who are taught using problem solving methods and the method of Conceptual Understanding Procedures (CUPs) in class VII students of SMP Negeri 14 Buton Tengah.

Objective of this research was to know the effect of guided discovery method on students’ Mathematics learning achievement at grade VII of SMP Negeri 18 Buton. This research was quantitative research with experimental method and using guided discovery method. Population in this research was all students at grade VII of SMP Negeri 18 Buton. Sample of this research was taken with using purposive sampling technique that was class VII4 as an experimental class and VII3 as a control class. Data collection technique in this research was using test. Outcomes of this research obtained: 1) the average of students’ Mathematics learning outcomes on the initial test in both the control class and the experimental class were respectively 51.07 and 47.36. while the average of students’ Mathematics learning outcomes on the final test of the control class and the experimental class was 69.14 and 67.29. 2) based on the result of hypothesis test with t test obtained the value of t_count = 0.676 and the value of t_table = 1.70562. When compared t_count with t_table so t_count < t_table sig (2-tailed) 0.0505 > 0.05, so that H₀ was accepted and H₁ was rejected. So, it could be concluded that there was no effect significantly on Mathematics learning outcomes wth student who got learning with guided discovery method and student who got conventional learning. So, it could be said that there was no effect between learning with guided discovery method or it could be said that the application of the guided discovery method was not effective in learning in terms of students’ Mathematics learning achievement at grade VII of SMP Negeri 18 Buton.

The purpose of this research was to see the effectiveness of digital-based learning in terms of the mathematics learning outcomes of class VIII students of SMP Negeri 2 Baubau. This research uses a quantitative approach with a quast-experimental type of research. The population in this study were all class VIII students of SMP Negeri 2 Baubau which were spread over 11 classes. The sample used is a saturated sample, because the existing population has homogeneus learning outcomes, then the sample is taken in two classes, namely class VIII.2 and class VIII.3. Data collection technique in this study use tests. The result of the research is that the significance value is 0.028, the N-Gain value is obtained from the difference in the average value of mathematics learning outcomes for experimental class students of 66.93 and control class of 57.10. Then the effectiveness criteria are based on the gain score, the percentage of the experimental class is 66.93% which is included in the quite effective category because it is between 56% to 75%, then H₀ is rejected and H₁ is accepted based on the hypothesis acceptance criteria, this means that the application of digital-based learning is quite effective in terms of the mathematics learning outcomes of class VIII SMP Negeri 2 Baubau on the subject of statistics.
