Partisipasi siswa memiliki peran penting dalam keberhasilan belajar. Partisipasi aktif siswa bisa mencapai tujuan belajar sehingga siswa bisa berprestasi akademik lebih baik. Partisipasi aktif dapat dipraktekkan dalam pembelajaran kooperatif dengan berdiskusi dalam kelompok atau kelas. Pembelajaran yang efektif dengan menggunakan pembelajaran kooperatif harus dirancang sebelum proses pembelajaran. Menurut analisis dan hasil refleksif, sebagian besar siswa di kelas telah mengikuti kegiatan belajar. Partisipasi aktif dikaitkan dengan berbicara atau memberikan pendapat, menjawab dan mengajukan pertanyaan untuk memberi ceramah atau memberikan komentar dalam diskusi di kelas. Di sisi lain, ada beberapa siswa yang pasif berpartisipasi dalam kegiatan belajar. Siswa tidak memberikan respon perilaku selama kelas. Siswa hanya perlu mendengarkan tanpa mencatat apapun. Kata Kunci : Partisipasi, pembelajaran kooperatif, lesson study

Pada dunia pendidikan, kemampuan berpikir kritis kini menjadi penting untuk dikembangkan guna menghadapi tantangan abad ke-21. Keterampilan berpikir kritis diperlukan dalam rangka membuat keputusan yang diawali dari serangkaian proses berpikir secara reflektif dan beralasan. Penelitian ini bertujuan untuk mengidentifikasi kemampuan berpikir kritis 30 mahasiswa menggunakan metode tes dan wawancara. Hasil tes kemudian dianalisis secara kuantitatif dan selanjutnya dideskripsikan ketercapaian indikator berpikir kritis pada setiap soal. Hasil analisis tes menunjukkan bahwa 23.33% atau 7 mahasiswa atau yang mulai berpikir kritis. Kelima indikator berpikir kritis hanya mampu dicapai oleh kurang dari 25% mahasiswa. Hanya 4 siswa yang berhasil mencapai kelima indikator berpikir kritis hingga menarik kesimpulan dengan tepat.Kata kunci: berpikir kritis, indikator berpikir kritis, kemampuan berpikir kritis

Let G be nontrivial and connected graph. A total-coloured path is called as total-rainbow if its edges and internal vertices have distinct colours. For any two vertices u and v of G, a rainbow u−v geodesic in G is a rainbow u−v path of length d(u,v), where d(u,v) is the distance between u and v. The graph G is strongly rainbow connected if there exists a rainbow u−v geodesic for any two vertices u and v in G. The strong rainbow connection number of G, denoted src(G), is the minimum number of colors that are needed in order to make G strong rainbow connected. The result shows for 1 Spl - (Cn) and 3 ≥ n ≥ 10 there exist a coloring where diam(G) = rc(G) = src(G) ≤ m and diam(G) ≤ rc(G) ≤ src(G) ≤ m with m is the number of path 1 Spl - (Cn).

Mathematical reasoning is the student’s ability to think logically regarding mathematics problems. The indicators of mathematical reasoning used in this study are presenting statements mathematically, performing mathematical manipulations, compiling the proofs for the truth of solutions, and drawing conclusions from statements presented. This study used qualitative research methods and aims to describe the students' mathematical reasoning abilities for the subject of Three Dimensions, reviewed by their learning independence during Distance Learning. This research was conducted at SMAN 1 Pasuruan class XII MIPA 1 for the 2021/2022 academic year. The instruments used in this study are learning independence questionnaires, mathematical reasoning ability tests, and guides for the interview. The results showed that 21 students can be categorized into Medium Level in terms of their learning independence, and 14 students can be categorized into High Level in terms of their learning independence. Students who have medium learning independence showed medium and low mathematical reasoning abilities. Students are able to solve problems by fulfilling two indicators of mathematical reasoning ability. On the other hand, students with high learning independence showed high mathematical reasoning abilities. Students are able to solve problems by fulfilling all indicators of mathematical reasoning abilities.

Students' critical thinking skills in learning are very important to have in the 2013 curriculum. The purpose of the study was to describe the critical thinking skills of students in SMP Negeri 7 Jember class VII J in solving mathematical problems in algebraic material, in terms of reflective and impulsive cognitive styles. This research is a descriptive study that uses a qualitative approach with 4 research subjects from class VII J consisting of 2 reflective subjects and 2 impulsive subjects. Data collection techniques used are tests and interviews. Data analysis techniques were carried out by reducing data, presenting data and drawing conclusions. Technique of data validity using triangulation method. The results of the research that have been carried out are that reflective subjects are able to meet all of the FRISCO critical thinking indicators (Focus, Reason, Inference, Situation, Clarity and Overview) in solving critical thinking test questions tend to be thorough, take a long time and the answer is correct. Impulsive subjects were only able to fulfill some of all the FRISCO critical thinking indicators (Focus, Reason, Inference, Situation, Clarity and Overview), namely focus and situation. Impulsive subjects cannot solve critical thinking questions because they do not understand how to solve problems.

This study aims to describe students' spatial-visual ability in solving PISA questions in shape and space content based on David Keirsey's personality type are guardian, artisan, idealist, and rational. This type of research used in this research is descriptive qualitative research. Subjects in the study were eight students from Class XI MIPA 1 SMA Negeri 7 Kediri consisting of two students from each of the guardian, artisan, idealist, and rational personality type. The data collection methods used were questionnaires, tests, and interviews. The instruments used in this study were MBTI questionnaires, shape and space content PISA test questions, and interview guidelines. The results showed that the achievement of the characteristics of the eight spatial-visual abilities of the subjects differed. Students with guardian personality are able to fulfill two characteristics of visual-spatial intelligence consisting of pattern search and conceptualization, but unable to fulfill the characteristics of problem-solving and imagining. Students with artisal personality are able to fulfill two characteristics of visual-spatial intelligence which consist of pattern searching and imagining. Students with idealist personality are able to fulfill the three characteristics of visual spatial intelligence which consist of pattern searching, conceptualizing, and imagining. Students with rational personality are able to fulfill all the characteristics of visual abilities consisting of pattern search, conceptualization, problem solving, and complete imagination in solving shape and space content PISA questions. This can be seen from the results of solving the questions given and interviews conducted on the research subjects.

One of the problems that occur in mathematical subjects was the ability for students to solve problems that need the Higher Order Thinking Skills (HOTS) still low. This problem also occurs in high school students (SMA) in Jember. The cause of the problem was that the mathematics teacher has not been skilled in making HOTS problems and has not guided students to solve HOTS problems. To overcome this problem, training activities followed by 118 high School Mathematics teachers held on 02 February 2019 at the center of MGMP (Teachers' discussion group) in Jember. The methods used were sharing information, discussions, and assignments to made HOTS mathematical problems, observation, test, and giving questioner. The results gained were the teacher's knowledge of the HOTS problem increasing from the average score of pretest 62 to the average score of posttest 85. The teacher's ability to make HOTS problems was already in good category, and all participants (100%) actively participate in training activities and give positive responses to the activity. The community services activity need to be continued in the future, because it is very important for improving teachers’ professionalism.
