Teachers’ and Students’ Perception about Creative Thinking Skills, Immersed Integrated Science Learning, and project-based Learning: A cow dung waste issue

Abstract: The perception of science teachers and students on project-based immersed integrated science learning: A cow dung waste issue. This study aims to describe the perception of science teachers and students about creative thinking skills, immersed integrated science learning, and project-based learning of a cow dung waste issue. The survey method used in this study were interviews and questionnaire techniques. The interviews conducted with 7 science teachers respondents. The questionnaires distributed to 121 respondents of junior high school students in the Jati Agung Subdistrict. The results showed that 85.71% of teacher respondents did not know about immersed integrated model yet. They also have never implemented project-based learning, based on the students’ questionnaires, the teachers only gave assignments to 74.07% of student respondents and did not provide real problem-solving. The environmental problem occurs in Jati Agung Subdistrict is a large number of cow dung that causes pollution on the environment around society’s houses. As many as 71.43% of teacher respondents stated that they already knew about creative thinking. However, the creative thinking skills they knew are not relevant to the Torrance framework. Based on the results, teachers’ and students' perceptions of integrated science learning, project-based learning, and creative thinking skills are not according to their nature

MODIFIKASI ALAT PRAKTIKUM KIMIA INSTRUMEN BERBASIS PROYEK UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KREATIF MAHASISWA CALON GURU

Penelitian ini bertujuan untuk meningkatkan keterampilan berpikir kreatif mahasiswa calon guru melalui praktik modifikasi alat praktikum kimia instrumen berbasis proyek (PMS). Dalam penelitian ini dimodifikasi spektrofotometer sinar tampak (SST) dan spektrofotometer serapan atom (SSA). Metode yang diterapkan dalam penelitian ini adalah mixed-methods desain, model Embedded Experimental. Instrumen yang digunakan dalam pengumpulan data adalah tes keterampilan berpikir kreatif berbasis konsep Kimia Analitik, asesmen kinerja, tanggapan mahasiswa terhadap keterlaksanaan dan model praktik modifikasi alat SST dan SSA berbasis proyek, lembar penilaian partisipasi antara mahasiswa, dan pedoman wawancara. Penelitian ini diterapkan terhadap mahasiswa pendidikan kimia semester 6 Tahun Akademik 2015/2016 salah satu universitas di Provinsi Lampung, dengan jumlah mahasiswa kelas kontrol sebanyak 35 dan kelas eksperimen 34 orang. Hasil penelitian menunjukkan PMS berbasis proyek efektif untuk meningkatkan keterampilan berpikir kreatif mahasiswa ( = 0,56; d = 4,1) pada semua indikator yang diteliti yaitu originality, fluency, elaboration, dan flexibility; juga efektif untuk meningkatkan keterampilan berpikir kreatif mahasiswa berkemampuan akademik rendah. Model proses kreatif mahasiswa terdiri atas 5 tahap yaitu: mengenali masalah, persiapan, inkubasi, menemukan solusi, dan verifikasi. Alat SST dan SSA yang dihasilkan kinerjanya efektif, murah, mudah dalam pembuatan dan penggunaannya, serta selaras dengan Hukum Beer. Komponen alat SST terdiri atas green laser pointer sebagai sumber sinar, kuvet gelas sebagai wadah sampel, dan lux meter sebagai detektor sekaligus pencatat. Komponen alat SSA terdiri atas lampu natrium sebagai sumber sinar, las torch gas butana sebagai burner, spraygun dan kompresor sebagai nebulizer, dan lux meter sebagai detektor sekaligus pencatat.

This research was conducted to chemical education students 6th semester, Academic Year 2015/2016 one of the universities in Provinsi Lampung, with 35 students in the control class and 34 students in the experimental class. The results showed that the project-based VS and AAS modification practice effective to enhance students’ creative thinking skills ( = 0.56; d = 4.1) for all the indicators studied included originality, fluency, elaboration, and flexibility; also effective for improving students’ creative thinking skills with low academic ability. The students’ creative process model consists of recognizing the problem, preparation, incubation, solutions findings, and verification. The performance of VS and AAS product was effective, inexpensive, easy to be built and use, and in accordance with Beer's Law. VS apparatus components consist of a green laser pointer as a light source, a glass cuvette sample containers, and a lux meter as a detector and a readout. AAS apparatus components consist of a sodium lamp as the light source, welding torch butane gas burner, a spray gun and a compressor as a nebulizer, and a lux meter as a detector and a readout. VS and AAS apparatus can be used both as a model in instruments chemistry lectures, and a measurement tool. Students response were positive to the practice of a project-based VS and AAS apparatus modification. Further research was needed to improve the performance of equipment VS and AAS, especially for measurement purposes

Teachers' Perceptions on the Development of Project-Based Learning Program for Vegetable Waste Treatment to Increase Students’ Scientific Creativity

Conventional learning that is still applied by teachers causes the quality of human resources in Indonesia to be still relatively low. Teachers should apply learning that can increase the skills needed in 21st century, one of these skills is scientific creativity. In this study to find out the teacher's perspective regarding project-based learning of vegetable waste processing to increase e students' scientific creativity. The research method used is a mixed method with Sequential Explanatory Design. Data collection was carried out by distributing questionnaires to 10 science teacher respondents at junior high schools in Tanggamus. The collected data were analyzed using descriptive analysis. The results of the study show that there are still many teachers who apply the lecture method and 100% of the teacher respondents have never implemented project-based learning and have never solved real problems such as processing vegetable waste in science learning. In fact, the problem that occurs in East Kotaagung District is vegetable waste that is not properly processed. As many as 100% of teacher respondents did not know students' scientific creativity, so they had never been able to increase students' scientific creativity. Based on the teacher's perception of these findings, it can be concluded that it is necessary to develop a learning program based on a vegetable waste processing project to increase students' scientific creativity.Conventional learning that is still applied by teachers causes the quality of human resources in Indonesia to be still relatively low.

Science Teachers’ Perception About Laboratory Activity on Mixture Separation Topics

The design of this research is survey research. This study aimed to explore seventh-grade science teachers’ perception of laboratory activity on mixture separation topics and match them with available evidence from learning document. The sample comprised 10 seventh grade science teachers, purposively sampled from seventeen teachers. Questionnaires and interview guidelines were used to collect data. The results show that while teachers’ perceptions of mixture separation topics in science classrooms are inadequate. Caused, there was a mismatch between teachers’ perceptions, learning document, and what was taking place in the science classroom. The study may inform teachers’ performance in teaching mixture separation topics in science. It is recommended that teacher on learning should be used to practice worksheet and assessment of laboratory activity, as most of the teachers do not record marks regularly for laboratory activity. Furthermore, laboratory activity prepared by the teacher should be arranged in a lesson plan and practice schedules
