The Project Based Laboratory Learning (PJBLL) model is an innovative physics teaching model designed to enhance student’s sciences process skills and creativity. Therefore, this research aims to analyze the effectiveness of PJBLL model to improve sciences process skills and creativity physics students who were programmers in Unesa’s laboratory. The study design used one-group pretest-posttest design. Data collection methods were conducted by using tests sciences process skills and creativity. Data is analyzed using Paired t-test and N-gain. The results of the study show that there was a significant increase in student’s sciences process skills and creativity at α = 5% with N-gain average of moderate category. Thus, the PjBLL model is effective for enhancing student’s sciences process skills and creativity.
The purpose of this study explains the effectiveness of the student activity sheet model to enhance scientific creativity and student learning outcomes and student responses to the learning process. The research design used pre-experimental with one group pretest-posttest design. The study's subject was the student activity sheet (SAS) model and the implementation of primary teacher Education undergraduate students who programed a science introductory concept course during the 2019.1 registration at Open University. Data collected using test methods and questionnaires with product cognitive test instruments, cognitive process tests, scientific creativity tests and student questionnaire responses. Data analyzed by t-test and the proportions calculated. Normality test and homogeneity test are done before the t-test is applied. Increased creativity and student learning outcomes are calculated using normalized N-Gain. The results showed: 1) Improvement of students' scientific creativity after joining learning in the medium category. 2) Improving student learning outcomes after participating in learning in the good category. 3) Student responses to the learning process in the positive category. Based on the above, it can be concluded that the application of student activity sheet model used in learning activities to improve scientific creativity competency and student learning outcomes is effective.
Mathematical thinking is divided into lower-order thinking skills (LOTS) and higher-order thinking skills (HOTS). The LOTS is consisted of recall thinking and basic thinking, while HOTS required a more complex thinking abilities such as critical thinking and creative thinking. This research is aimed to develop a valid, effective, and practical HOTS-based worksheet for S-1 PGSD students who took Mathematics course in Universitas Terbuka. The application of HOTS-based worksheet is expected to be able to improve students’ learning motivation, as well as their ability in thinking critically and creatively in solving mathematical problems. The research is a developmental research, and the obtained data were analyzed descriptively. The subjects of this research were 72 students of S-1 PGSD program Universitas Terbuka Surabaya who took Mathematics (PDGK4108) course. The results showed that the developed HOTS-based worksheet fulfils the validity, practical, and effective criteria to improve students’ learning motivation, which can be seen that 77% of students (56 students) felt encouraged and motivated to think critically and creatively, 72% of students (52 students) showed the ability to solve problem based questions. Furthermore, 78% of the students (41 students) achieved 75 out of 100 score or more. It can be concluded that the application of the developed HOTS-based worksheet is suitable in teaching Mathematics. Kemampuan berpikir dalam matematika dibagi atas kemampuan berpikir tingkat rendah (low order thinking skills disingkat LOTS) dan berpikir tingkat tinggi (high order thinking skills disingkat HOTS). Berpikir yang tergolong LOTS meliputi berpikir memanggil (recall thinking), dan berpikir dasar (basic thinking),sedangkan yang tergolong HOTS meliputi berpikir kritis (critical thinking) dan berpikir kreatif (creative thinking). Penelitian ini bertujuan mengembangkan LKM (lembar kerja mahasiswa) berbasis HOTS pada matakuliah Matematika di program S-1 PGSD UT yang valid, efektif dan praktis. Pendekatan tutorial dengan menggunakan LKM HOTS ini, diharapkan dapat meningkatkan motivasi belajar mahasiswa dan meningkatkan kemampuan berpikir kritis serta meningkatkan kemampuan dalam mengerjakan soal-soal matematika sehingga dapat meningkatkan hasil belajar. Jenis penelitian adalah penelitian pengembangan (developmental research) dan deskriptif. Subjek penelitian sebanyak 72 mahasiswa program S1 PGSD UPBJJ UT Surabaya yang mengambil mata kuliah Matematika (PDGK4108). Hasil penelitian menunjukkan bahwa LKM berbasis HOTS yang dikembangkan memenuhi kriteria valid, praktis danefektif, untuk meningkatkan motivasi belajar mahasiswa, ditunjukkan oleh 77% (56 mahasiswa) yang merasa tertantang dan termotivasi untuk berpikir tingkat tinggi (kritis, dan kreatif), 72% (52 mahasiswa) mampu menyelesaikan soal-soal yang bersifat pemecahan masalah, dan dari mahasiswa yang mampu tersebut ada sebanyak 78 % (41 mahasiswa) mendapat nilai lebih dari atau sama 75 dari skor maksimal 100. Penelitian ini menyimpulkan bahwa LKM bebasis HOTS yang dikembangkan cocok untuk diaplikasikan dalam pengajaran matematika.
