This action research aims to improve the profile of collaborative Pancasila students and mathematics learning outcomes in class VIII students at Public Junior High School 5 Sanggau. This action research is a single class research. The implementation time starts from October 23 to November 8, 2021 which is divided into 4 meetings (pretest, treatment 1, treatment 2, posttest). The design used in this research is The One-Group Pretest-Posttes Design. This design was used in group research, namely class VIIIA which was given treatment in the form of applying the Discovery Learning of two-variable linear equation (PLDV) material. Based on the results of the analysis of the observation sheet, an increase of 25% was obtained where at the first 2 treatment meetings, 65% of students actively collaborated while in the treatment , 90% of students actively collaborated. Student learning outcomes showed an increase of 50%, where the results of the pretest showed 42.85% and the post was 92.85%. In addition, the results of data processing on the normality test showed that the pretest 0.197 > 0.05 meaning the data was normally distributed, the data homogeneity test showed sig 0.108 > 0.05 meaning the data was homogeneous and the T test showed a significance = 0.00 so it can be concluded that the hypothesis is accepted. means that there is an increase in the value of the pretest with the posttest.

This study aims to improve student’s learning outcomes on material Flat Sides Solid Figure using worksheet (LKPD) especially for 8th grade class-A student of SMP N 5 Sanggau. The method used was classroom action research. The subjects in this study were 8th grade class-A students. Data collection techniques used observation, measuring, and documentary studying techniques. The instruments used were written test. Based on the result, there is a significant improvement on student’s learning outcomes. It proved by the improvement numbers of student who passed the exam after 2nd Cycle. Which were improved from Pre-Cycle, 1st Cycle, 2nd Cycle are 34%; 73,08%; 92,30% while the averages are 69; 70,96; and 80,08. It proved that applying offline learning models with LKPD in covid-19 pandemic on mathematic will improved students’ learning outcomes. The learning process was morelively because students have a chance to build their own knowledges based on what they learned..

This Scientific Review in the form of best practice Learning the ELPSA (Experience, Language, Picture, Symbol, Application) model examines learning as an active process where students construct their own way of understanding things through individual thought processes and social interactions with others in BDR activities. In this BDR activity, LKPD is used. This Scientific Review (Best Practice) activity aims to improve understanding of the concept of integer operations through ELPSA learning for class VIIA students of SMPN 5 Sanggau. This activity is carried out in the 2021/2022 school year, to be precise in July. The success criteria set by the researchers are student activities during the BDR learning process in the good category, at least 80% of the number of students can reach the KKM which is 70. The results of this scientific review show that students' understanding of learning integer operations through ELPSA learning when BDR has been achieved by the success criteria shown in the post test results. In more detail, the percentage of achievement of the success criteria is as follows: 1) student activities during the learning process are in the good category, 2) There is an increase in the percentage of students who have reached the KKM by 31.25% from pre-test 56.25% to 87.5% in post test. From the results of the study, it can be concluded that ELPSA learning is effective in increasing the understanding of the concept of integer operations during BDR.
