Abstract

Difficulty understanding students' concepts needs to be known so that improvements can be made so that eventually students can master the concepts well. Misconception diagnostic tests can be an alternative to uncovering causes or factors of misconception in students. This study aims to develop a Four-Tier Test diagnostic test instrument to diagnose students' misconceptions on circular motion material. This research is a development study using 4D models. The developed four-tier test diagnostic test instrument consists of 40 multiple-choice questions. The results of the content validation by five experts stated that the instrument was very feasible with an average percentage of 86,34%. Empirical trial results show as many as 40 valid diagnostic test items have enough to good power a level of difficulty and discrimination power. The reliability of the questions was analyzed using the Kuder Richardson formula of 0.785 with a high category. This instrument can be used to minimize the time spent in the process of identifying misconceptions because it is in the form of multiple-choice with varied questions.

Abstract

Tingginya penggunaan gadget di kalangan anak usia sekolah dasar memicu kekhawatiran terhadap dampak negatifnya terhadap perkembangan kognitif, sosial, dan emosional. Kegiatan pengabdian masyarakat ini bertujuan untuk mencegah kecanduan gadget melalui pendekatan psikoedukatif dan penguatan positif kepada siswa kelas 5 MI Al Fattah dengan jumlah 20 siswa. Kegiatan dilakukan melalui penyampaian materi interaktif mengenai penggunaan gadget yang sehat, serta pemantauan perilaku anak di rumah selama tiga hari oleh orang tua. Pemantauan di lakukan menggunakan tabel yang telah di sesuaikan untuk target perilakunya, dari hasil pemantauan menunjukkan adanya penurunan durasi penggunaan gadget dan peningkatan aktivitas seimbang. Respons siswa terhadap pengingat dari orang tua juga menunjukkan peningkatan dari hari ke hari. Wawancara dengan wali kelas memperkuat temuan ini, di mana guru menyatakan bahwa siswa tampak lebih sadar waktu, lebih aktif di kelas, dan menunjukkan perubahan perilaku yang positif. Kolaborasi antara pihak sekolah dan keluarga melalui reinforcement positif terbukti mampu membentuk kebiasaan penggunaan gadget yang sehat sejak dini. Kegiatan ini tidak hanya memberikan kontribusi praktis dalam pembentukan karakter digital anak, tetapi juga memperkaya referensi teoritis terkait intervensi preventif terhadap adiksi teknologi di lingkungan pendidikan dasar.
