Abstract

The result of 2015 PISA (Program for International Students Assessment) test which placed Indonesia in the 65th position of 72 countries showed the importance to improve the level of students thinking ability. There are many ways to improve the students’ thinking. One way to do that is by giving the students drill to solve higher order thinking problems. However, this solution is difficult to implement because designing HOTS (Higher Order Thinking Skills) problem is difficult for the teachers. Therefore, 20 junior high school mathematics teaches ware selected in order to give them training and workshop to improve their ability to design higher order thinking skills using action research methods. Three stages ware implemented in this training and workshop. First, introduction to HOTS, Second, designing HOTS Problems, and third, trying out and evaluating the test result. Product of the workshop are 30 mathematical problems in certain topic in which 15 of them are HOTS problems. To measure the effectiveness of the training and workshop, the result of pre-test and posttest were compared. Based on the data analysis, there was an increase of the ability of mathematics junior high school teachers to design problems to assess the higher order thinking skills.

Abstract

Abstract – To accomodate High Order Thinking Skills (HOTS) in classrom, we need to consider curricula, learning process, and assesment. Learning process and assesment have an essential requirement i.e. teacher’s ability. Government has done some activity to increase teacher’s ability to apply HOTS in classrom, but teachers need more. To keep their motivation and ability, teachers need a continue activity related to HOTS. Lecturer is an academic expert who teach in university level. In Indonesia, service to community is one of obligation for lecturer. Hence increasing teachers understanding about HOTS is one of lecturer’s duty. Training and workshops has been designed to rose teachers ability in creating HOTS problems and teaching using those problems. In this activity, teachers are studied about HOTS concept, the government policy about HOTS, solve some HOTS problem in National level test, and how to create HOTS base mathematical problems. For the next activity, teachers are asked to create some HOTS base mathematical problems, and design a learning trajectoty/ design to put their HOTS problem in learning process. Lastly, base on teacher’s satisfaction questionnaire, teachers are very happy to get this activity for the activity’s programme, mastery of topics, and teacher ‘s needs.

Abstract

Laboratorium activity and experiment related to Dynamic Electricity topic in secondary schools have always been a “scary” thing to science teachers in Indonesia, especially to those with more experience in teaching Biology than Physics. To our surprise, the problem was more related to teacher’s confidence to conduct lab acitivy rather than to the availability of experiment kit in school. Our visit to two schools in Padang revealed that each school has sufficient amout of experiment kit for Electricity but the science teachers were too scared to take students to lab and get nervous when something is not working, or too scared to damage the kit. Therefore, we would like to offer a solution to overcome this problem by intoducing an easy do-it-yourself simpe electricity circuit with potato. The activity is expected to build more confidence in teachers to conduct lab activity and make science learning more fun to the students. Keywords — electric circuits, electricity from potato, school science, simple science experiment, dynamic electricity

Abstract

Pandemik covid 19 yang telah berlangsung selama 9 bulan telah membuat perekonomian porak poranda. Bagi petani kecil holtikutura/petani sayur satu satunya cara untuk tetap bertahan adalah dengan cara peningkatan kemampuannya untuk menciptakan strategi kemandirian, baik dari aspek produksi maupun pemasaran. Kemandirian petani untuk melakukan produksi sendiri tanpa bergantung pada penyediaan input produksi yang dijual di pasar, petani harus dapat menyediakan bibit dan pupuk untuk berproduksi, tanpa terganggu dengan kenaikan harga input produksi di pasar. Cara terbaik adalah dengan melakukan pertanian organik, sehat untuk dikonsumsi dan lingkungan terjaga terhindar dari keracunan residu kimia. Saat ini kasus keracunan pangan masih menghantui Indonesia. Keracunan makanan menempati urutan kedua setelah KLB difteri. Oleh sebab itu untuk mengurangi kasus tersebut atau meminimalisir maka masyrakat dituntut untuk mengonsumsi makanan sehat dan bergizi. Pangan yang sehat dan bergizi tinggi dapat diperoleh dari teknik pertanian yang juga sehat yaitu menggunakan metode pertanian yang organik.

Abstract

The increasing number of positive cases of COVID-19 in Indonesia has prompted the Ministry of Education and Culture (Kemendikbud) to recommend online learning as an effort to reduce the spread of the virus. The use of new online learning technology is dominated by SMA / MA in big cities because of the financial capacity and availability of a digital learning system that is better than SMA / MA in remote areas. The problem currently faced is the unavailability of teaching materials oriented to the online learning process (e-learning) in accordance with the demands of the 2013 Curriculum and the ability of most educators to prepare teaching materials for independent online learning still needs to be improved. Therefore, community service training in the development / manufacture of teaching materials that is oriented to the guided inquiry learning model and applies three types of representation to express chemical ideas, so that the chemistry learning process produces three learning levels, namely symbolic representation, macroscopic and sub-microscopic, or molecular. Have been trained to use Camtasia aplication.
