Abstract

The training activity for creating innovative learning media in the independent curriculum was carried out in order to develop the competence and skills of teachers related to creating creative and interesting learning media. The activity was carried out in Kolbano, South Central Timor Regency, East Nusa Tenggara Province in 2024. The basis for its implementation was the need for teachers to develop their competence in utilizing technology in creating learning media according to the demands of the current independent curriculum. This activity aims to improve teacher competence in utilizing technology to design interesting and innovative learning. The innovative learning media that were the topic of this training were Google Sites, Wordwall and QuizWhizzer. Teachers in Kolbano generally only teach using lecture and group discussion methods, and use conventional learning media such as power point displays and video materials. As a result, students are less motivated and feel bored in learning activities, while the nature of the independent curriculum demands active interaction of students in learning. Therefore, through this training, teachers are trained and assisted in developing innovative learning media until the product is produced and used in learning. This learning media can be presented interactively and attractively so that it can motivate students to participate in learning. Teachers will also be more creative in innovating to develop media that attracts students' interest in accordance with the nature of the independent curriculum.

Abstract

Telah dilakukan survei pengelolaan bahan kimia kadaluarsa dan limbah praktikum terhadap mitra yakni guru-guru kimia yang tergabung dalam Ikatan Alumni Pendidikan Kimia FKIP Undana (IUPAC). Survey menggunakan kuisioner via google form dan telah diisi oleh 25 guru dari 25 sekolah yang berbeda yang ada NTT. Hasil survei menunjukkan bahwa 96% sekolah tidak memberi perlakuan sebelum limbah praktikum dibuang. Limbah praktikum tersebut langsung dibuang pada: tempatnya (48%); alam bebas (32%); wastafel (12%); dikubur (4%); sedangkan 4% sekolah memiliki perlakuan sebelum limbah dibuang (diencerkan). Selain itu bahan kimia kadaluarsa dimiliki 11 dari sekolah 25 (44%) dengan cara penanganannya seperti disimpan (64%) dan dikubur (36%). Berdasarkan hasil survei ini dapat disimpulkan pemahaman mitra kurang dalam mengelolah limbah hasil praktikum maupun bahan kimia kadaluarsa. Solusi yang ditawarkan untuk mitra adalah memberikan sosialisasi dan konsultasi yang dilaksanakan secara daring. Dilanjutkan kegiatan pendampingan kepada sekolah sampel dalam pengelolaan bahan kimia kadaluarsa dan limbah praktikum

Abstract

An investigation was conducted at A State Senior High School in Kupang City, NTT.to assess how Project-Based Learning (PjBL) and Discovery Learning (DL) models differentially impact student learning activities and outcomes when teaching atomic structure. Adopting a quasi-experimental design with a nonequivalent control group, the study collected data through comprehensive activity questionnaires, observation sheets, and pretest/posttest instruments. The findings clearly showed that PjBL significantly boosted student learning activities, with an average score of 81.19, considerably higher than the 66.15 observed in the DL group. This significant difference was statistically confirmed by an independent samples t-test. Regarding learning outcomes, the PjBL group's average (70.97) was marginally better than the DL group's (68.89), but this difference did not reach statistical significance. It is suggested that limitations in learning time may have played a role in the learning outcomes. This study concludes that PjBL is superior for enhancing student engagement and activity, while both PjBL and DL are equally effective in improving student learning outcomes. Ultimately, the choice of a learning model should be strategically aligned with educational goals, subject matter, and the unique characteristics of the classroom to maximize student achievement.

Abstract

The dedication to this community is the training of teacher competence development related to learning media that is carried out for teachers in the Nekamese, Kupang District, East Nusa Tenggara Province in the year 2023. The implementation is based on the need for teachers to develop competence against the use of technology in making learning media in accordance with the requirements of the independent curriculum in force today. This activity aims to enhance the competence of teachers in the use of technology in order to design interesting and innovative learning. In today's digital age, teachers are not only required to improve their teaching skills based on their material knowledge, but are also required to be able to apply innovative and enjoyable learning to encourage and motivate students in learning and thinking at a high level. The learning media used in this activity is the creation of teaching materials using exe learning, live worksheet and instrumentation using blookets. There are still many teachers in the Nekamese district who have never developed innovative teaching materials with the use of technology. Usually the teachers only teach in front of the methods of lectures and group discussions, and still give the questions of practice or examination in the form of manuals. As a result, students are less motivated and tired of learning. Therefore, through this training, teachers are trained and guided in creating gamification-based material and instruments until the product is produced and applied in classroom learning. This learning media can be presented in an interactive and interesting way so that it will motivate students to follow the learning. Teachers will also be increasingly creative in innovating to develop teaching materials and instruments of interest to students.

Abstract

Technological advances provide educators with the freedom to create quality learning that meets the needs and learning environment of students. A crucial aspect for teachers to consider in realizing effective learning is the use of interactive learning media tailored to the characteristics and needs of students. The use of digital technology to develop interactive learning media is a necessity in today's learning process. Training and mentoring for teachers in Malaka to develop interactive and innovative digital media is based on the need to improve their competency and skills in utilizing technology to develop learning media. This activity aims to improve teachers' competency and skills in utilizing technology to design engaging and interactive digital-based learning using Book Creator and QuizWhizzer. Monotonous learning activities, often based on lectures and group discussions, with the use of conventional learning media, tend to make students passive and easily bored, resulting in a lack of student interest in learning and a decline in the quality and outcomes of learning. Furthermore, technological developments demand increased competency, including in preparing engaging learning media. Therefore, through this training activity, teachers are provided with guidance and training in developing interactive learning media so that the resulting products can be directly used in the learning process. The developed media is designed to be interactive and engaging, thereby increasing student motivation. Furthermore, this activity also encourages teachers to be more creative and innovative in creating learning media that can attract student interest. The training activities ran smoothly and effectively, as evidenced by the high enthusiasm of teachers and the increase in knowledge and skills related to the training material. The mentoring results also showed an improvement in the quality of learning through active student interaction in learning with the help of digital learning media, which resulted in improved interest and learning outcomes.
