Abstract

This study aims to design a science learning program based on the local wisdom and apply it in elementary school. Mixed method research was use to gain the significance improvement from the design. There were 35 elementary science teachers from 16 elementary schools chosen by using purposive random sampling. The previous research revealed that there are about 80% of the teachers who were recognized the local wisdoms in their environment, but none of them have a capability to use it as a part of their science program in the classroom. To overcome this constrain, Review(R), Task(T), Solution(S), Reflection(R), and Evaluation(E) design was proposed in elementary school science learning. By implementing the design in two elementary schools, 11 positive characters expected were indicated from students’ performance. But characters of honest, disciplined, conscientious, diligent, careful, responsibility, and caring environment, are most significant. Tujuan dari penelitian ini adalah mengembangkan desain pembelajaran sains berbasis kearifan lokal pada tingkat sekolah dasar. Metode penelitian campuran (mixed method) digunakan untuk melihat signifikasi capaian pengembangan desain. Penelitian ini melibatkan 35 guru dari 16 sekolah dasar yang dipilih secara acak dari sekolah-sekolah yang memenuhi kriteria yang telah ditetapkan. Dari penelitian sebelumnya diperoleh hasil bahwa sekitar 80% dari sampel telah mengenali kearifan lokal di lingkungan sekolah masing-masing. Namun, tidak satupun dari sampel yang memiliki kapasitas untuk mengaplikasikan kearifan lokal tersebut ke dalam kurikulum sains mereka. Untuk mengatasi kendala ini, maka digagaslah desain Review(R), Task(T), Solution(S), Reflection(R), dan Evaluation(E) ini. Dua sekolah dipilih secara purposive sampling sebagai kelas eksperimen. Dengan mengkombinasikan dari kualitatif hasil RnD desain dan data kuantitatif nilai tes, diperoleh informasi bahwa 11 karakter positif terindikasi pada performan siswa. Dari kesebelas karakter tersebut, kejujuran, keingintahuan, jujur, hati-hati, tanggung jawab, dan peduli lingkungan yang paling meningkat secara signifikan.

Abstract

The purpose of this study is to develop computer-based experiment of free fall movement to improve the graphical literacy of the Physics Education students. This study employed quasi-experimental design, particularly the pre-test and post-test control group design. The sample was 58 students of the first semester of Physics Education study program. They were divided into two groups, namely 38 students constituted an experimental group and 20 students constituted the control group. Both groups joined learning activities at laboratory and classrooms with the same topic which is the free fall movement. Computer-based learning models were used to design learning activities for the experimental group, while the control group used a traditional learning model with manual experiment with stopwatch and never use experiment tool of free fall movement. It was indicated in this study that the use of such learning model improved the graphical literacy capability better than the traditional learning, which covered ability to identify experimental variables, using the experimental tools, making a graph, formulating mathematical equation, making predictions on the basis of the graph.

Abstract

This research aims at investigating elementary school student achievement based on the use ofscientific method in teaching science from the test item types, as reflected by the item difficulty indexusing the classical test theory (CTT) and modern test theory (IRT). The first stage in developing the test was preparing the learning continuum of scientific method aspects by referring to the learning continuum of science process skill as developed by the previous existing research. In this research, the learning continuum was validated by expert judgment. As the tests were administered/carried out at the same time, four sets of tests were developed and administered to students of Grade 1 to 6 in Yogyakarta and Sleman Regency in the 2016-2017 school year. Samples were taken from three Technical Management Units (TMUs). Three TMUs were determined by observing the distribution of school locations from the center to the suburbs. The items were analyzed using CTT and IRT.The results of the research show that the student achievement reflected by item difficulty index based on CTT and IRT indicates the same level of category except for several sub-aspects. Those items from certain testsindicate higher difficulty level for Grade 4 to 6 students than for Grade 1 to 3 students. This case is not relevant to the expected learning outcomes.

Abstract

Energy is one of the basic concepts in physics which is included as an abstract concept that is not easily captured by students to its physical properties. Therefore it is necessary to optimize the experimental tool in physics learning, especially in the learning of mechanical energy to facilitate understanding the concept. Technology research is growing rapidly and is able to contextually present abstract phenomena that are sensor-based technology and one of them is an ultrasonic sensor. This study aims to develop a mechanical energy experimental tool using ultrasonic sensors to facilitate students in understanding the concept of energy. The development of the experimental tool used research and development methods. To test the feasibility of the experimental tool developed and the accompanying practicum module, a series of feasibility tests have been carried out including calibration tests, feasibility tests by physicists, and empirical tests by users. The instrument used is a checklist item compiled based on the standard indicators of the feasibility of an experimental tool. The results of the development showed that the experimental tool had a precision percentage of 98.1% and a high accuracy of 99.99% with a value of t = (0.383 ± 383X10-4) s. Based on the feasibility test by physicists 93.75% of indicators as standardized experimental tools have been achieved, as well as the experimental modules fulfilling 90.90% of the standard set. Similar results were also report by users that the experimental tool was feasible to be used in schools’ level, but there were still obstacles related to the sensitive nature of ultrasonic sensors with surrounding movements and constraints in making variable variations to be tested which had an impact on the less optimal graphic display.Energi merupakan salah satu konsep dasar fisika yang memiliki sifat abstrak yang sulit ditangkap makna fisisnya oleh siswa. Oleh sebab itu diperlukan optimalisasi alat eksperimen dalam pembelajaran fisika khususnya dalam pembelajaran energi mekanik untuk mempermudah pemahaman konsep tersebut. Penelitian bidang teknologi yang berkembang pesat dan mampu menghadirkan secara kontekstual fenomena yang abstrak adalah teknologi berbasis sensor dan salah satunya adalah sensor ultrasonik. Penelitian ini bertujuan untuk mengembangkan alat eksperimen energi mekanik dengan menggunakan sensor ultrasonik untuk memfasilitasi siswa dalam memahami konsep energi. Pengembangan alat eksperimen ini menggunakan metode research and development. Untuk menguji kelayakan alat eksperimen yang dikembangkan dan modul praktikum yang menyertainya, maka telah dilakukan serangkaian uji kelayakan termasuk uji kalibrasi, uji kelayakan oleh ahli fisika, dan uji empiris oleh pengguna. Instrumen yang digunakan adalah item checklist yang disusun berdasarkan indikator baku kelayakan suatu alat eksperimen. Hasil pengembangan alat eksperimen energi mekanik berbasis sensor ultrasonik yang telah dilakukan menunjukkan bahwa alat eksperimen tersebut memiliki persentase ketepatan sebesar 98,1% dan ketelitian yang tinggi sebesar 99,99% dengan nilai t = (0,383 ± 383X10-4) s. Berdasarkan uji kelayakan oleh ahli fisika didapatkan 93,75% indikator sebagai alat eksperimen terstandar  telah tercapai, demikian juga dengan modul eksperimennya memenuhi persentase 90,90% dari standar yang ditetapkan. Hasil senada juga ditemukan oleh pengguna bahwa alat eksperimen tersebut layak untuk digunakan dalam kegiatan eksperimen di sekolah, namun masih terdapat kendala terkait sifat sensitif sensor ultrasonik dengan pergerakan sekitar dan kendala dalam melakukan variasi variabel yang akan diujikan yang berdampak pada kurang optimalnya tampilan grafik.
