Abstract

Abstract: This study aimed to compare the students’ learning outcome and science process skill that learned by two different methods viewed from prior knowledge. This study used the quasi-experimental design. The research‘s instruments were student‘s learning outcome and science process skill test. Data were analyzed using by MANOVA. The results showed that: (1) there was differences in student‘s learning outcome and science process skill that learned with guided inquiry based laboratory activities and verification based laboratory; (2)  there was no interaction between learning methods in laboratory activity and prior knowledge on student‘s learning outcome. Thus, the guided inquiry strategy has enhanced student’s learning outcome and science process skill.Key Words: guided inquiry, laboratory activity, prior knowledgeAbstrak: Penelitian ini bertujuan untuk mengetahui perbedaan hasil belajar dan keterampilan proses sains siswa yang dibelajarkan dengan dua metode berbeda ditinjau dari pengetahuan awal. Penelitian ini menggunakan rancangan penelitian eksperimen semu. Instrumen pengukuran yang digunakan dalam penelitian ini adalah tes keterampilan proses sains dan hasil belajar siswa. Data dianalisis menggunakan MANOVA. Hasil penelitian menunjukkan bahwa: (1) ada perbedaan hasil belajar dan keterampilan proses sains siswa yang dibelajarkan dengan praktikum inkuiri terbimbing dan praktikum verifikasi, (2) tidak terdapat interaksi antara strategi pembelajaran dalam kegiatan praktikum dan pengetahuan awal terhadap hasil belajar siswa. Simpulannya adalah praktikum inkuiri terbimbing dapat meningkatkan hasil belajar dan keterampilan proses sains siswa.Kata kunci: inkuiri terbimbing, kegiatan praktikum, pengetahuan awal

Abstract

The purpose of this study is to find out the description of the use of Android-based learning media using an inquiry approach to strengthen technological pedagogical and content knowledge (TPACK) for preservice teachers. The type of research used in this research is library research using descriptive analysis. The data used comes from secondary data, namely scientific journals in the form of articles. The data collection method used is documentation with data analysis techniques in the form of content analysis. Based on the results of the review of the journals that have been carried out, the results show that the use of Android-based learning media using the inquiry approach can strengthen the Technological Pedagogical and Content Knowledge (TPACK) of preservice teachers because it can train, shape habbit and provide confidence for prospective teachers to master the content of the material to be taught as well as integrating pedagogy with the technology used.

Abstract

Research has been carried out on the effect of potassium hydroxide catalyst concentration on the yield of coconut oil (Cocos nucifera) transesterification and continued to characterize the reaction results. The concentration of potassium hydroxide used was 1, 2, and 3% by weight of coconut oil with ethanol as the reactant. The data processing used was the one-way analysis of variation and its characterization from a physicochemical perspective, followed by the analysis of gas chromatography-mass spectroscopy (GCSM) and infrared spectrophotometry. Based on the data processing results, potassium hydroxide concentrations of 1, 2, and 3% did not affect the yield of the transesterification reaction of coconut oil, and the results were 74.5264%, 71.9330%, and 69.0420%. The characterization results show that the physicochemical properties of the reaction products, such as acid number, density, and viscosity, comply with the Indonesian National Standard (SNI) for biodiesel. The results of the GCMS analysis showed that nine peaks were dominated by ethyl laurate.

Abstract

Pendidikan merupakan aspek universalitas yang harus ada dalam perikehidupan umat manusia. Perkembangan teknologi informasi dan komunikasi telah merambah pada bidang pendidikan dan pengajaran, hal ini menuntut para pendidik untuk lebih meningkatkan kemampuannya seperti cara mengajar, materi ajar yang disajikan dan lainnya. Media pembelajaran merupakan perantara dalam menyampaikan suatu pesan yang didesain sehingga tujuan pembelajaran bisa dicapai. Penggunaan dari media pembelajaran sangat penting diterapkan, supaya pembelajaran tidak monoton dan dapat menarik perhatian peserta didik. Namun, hampir semua dosen muda UNIMA memiliki kemampuan dalam pembuatan media pembelajaran masih minim sehingga berdampak pada sulitnya peserta didik memahami proses pembelajaran. Kegiatan ini bertujuan memberi pelatihan dalam pembuatan media pembelajaran berbasis android yang dapat meningkatkan pengetahuan dan keterampilan dosen-dosen muda UNIMA dalam hal pembuatan media pembelajaran berbasis android. Pelatihan ini diharapkan dapat memberikan dampak positif dalam pengembangan pendidikan di UNIMA. Metode pelaksanaan dari pengabdian ini diawali dengan persiapan dan pelaksanaan. Hasil dari pengabdian yang dilakukan menunjukkan bahwa dosen muda di UNIMA memiliki antusias yang cukup besar dalam mempelajari dan mengembangkan media pembelajaran, ini dapat dilihat dari antusiasnya peserta pelatihan dalam mengikuti kegiatan ini.

Abstract

Flipped classroom is a learning approach where subject matter and skills that are usually taught during class hours are delivered outside the classroom. This research aims to determine differences in student learning outcomes through the application of the flipped classroom learning model on basic chemistry material in mathematics education at Universitas Negeri Manado (Unima). This research is quantitative research using experimental methods with a one-group pretest-posttest design. The sample used in this research was class A mathematics education students with a low or no level of understanding of chemistry. The data collection technique uses a learning outcomes test where a pretest is given before the lecture process is carried out and a posttest after the lecture process is carried out. The research results showed that the average student learning outcomes in the pre-test were 37.71 and the average student learning outcomes in the post-test were 87.88. The N-Gain score test results show a score of 81% which is included in the effective and high category. Based on these results, it can be concluded that the application of the flipped classroom model improves student learning outcomes in chemical bond material in the general chemistry class at Unima’s mathematics education effectively and significantly.
