Abstract

Integrity is honest, fair behavior and shows consistency between words and actions. In the field of education, the term academic integrity is known. Academic integrity is behavior that is in accordance with the norms of truth in the academic context. there are five aspects in academic integrity, namely honesty, trust, fairness, respect, and responsibility. Academic integrity is very important to have so that a person behaves ethically in the learning process. a decrease in academic integrity has the potential to affect students' professional lives when working later. Lack of integrity in academics in a person can be influenced by several factors, both internal and external. The internal factor causing the lack of integrity is academic anxiety. This happens because of the worries that arise over failure in the exam, so students do various ways to get good test scores. the purpose of this study is to determine with the application of the PjBL learning model, whether there are significant differences in learning outcomes between students with high, medium and low integrity. The project given in the application of the PjBL model is expected to provide a different, fun, meaningful and challenging learning experience for students. The method used in this research is through cluster random sampling technique. The application of PjBL in blended learning with a project-shaped evaluation model produces the same learning outcomes for the three integrity groups. With the highest average learning outcomes coming from the medium integrity group followed by the high integrity group and the lowest average coming from the low integrity group.

Abstract

Pentingnya kemampuan pemecahan masalah dalam pembelajaran matematika belum diikuti dengan pencapaian yang baik. Penelitian ini bertujuan menerapkan model pembelajaran Problem Solving dan Problem Posing serta menguji ada tidaknya perbedaan kemampuan pemecahan masalah dari kedua model tersebut. Penelitian dilaksanakan pada kelas X salah satu SMA Negeri di Salatiga dengan materi trigonometri. Sampel sebanyak 53 siswa, terbagi dalam dua kelompok eksperimen. Penelitian ekperimen semu ini menggunakan desain randomaized control group pretest-postest design, dengan instrumen berbentuk tes kemampuan pemecahan masalah dan lembar observasi. Analisis data menggunakan kovariansi pada taraf signifikan ???? = 5% dengan kemampuan awal sebagai variabel kovarian. Hasil uji hipotesis menyimpulkan bahwa dengan mengontrol kemampuan awal siswa didapat bahwa siswa yang melaksanakan model pembelajaran Problem Posing secara signifikan memiliki kemampuan pemecahan masalah matematika yang lebih baik dibandingkan siswa yang melaksanakan model pembelajaran Problem Solving. Hasil ini menunjukkan pembelajaran hendaknya tidak hanya melatih siswa menyelesaikan masalah tetapi juga mengkonstruksi permasalahan. The importance of problem-solving abilities in mathematics learning has not been automatically followed by good achievement. This study aims to apply Problem Solving and Problem Posing learning models and to test whether there are differences in the problem-solving abilities of the two learning models. This research was conducted in class X mathematics learning at one of the public high schools in Salatiga on Trigonometry material. This quasi-experimental study used a randomized control group pretest-posttest design, with instruments in the form of problem-solving ability tests and observation sheets. The data analysis used was the covariance test at the significant level α = 5% with the initial ability as a covariate variable. The results of hypothesis testing with covariance analysis concluded that by controlling students' initial abilities it was found that there were significant differences in mathematical problem-solving abilities between the application of the two models. Students who carry out the Problem Posing learning model significantly have better mathematical problem-solving abilities than students who carry out the Problem-Solving learning model. These results indicate that learning should not only train students to solve problems but also construct problems.
