Abstrak

Dalam proses pembelajaran di sekolah, peserta didik seringkali mengalami miskonsepsi meskipun konsep tersebut telah diajarkan sebelumnya. Salah satu penyebab miskonsepsi yang terjadi pada peserta didik yaitu berasal dari peserta didik itu sendiri. Peserta didik mengalami miskonsepsi terutama pada konsep-konsep abstrak seperti pada materi Hukum Newton. Oleh karena itu, untuk mendiagnosis miskonsepsi peserta didik pada materi Hukum Newton disusunlah instrumen tes diagnostik berformat four-tier. Selain itu, dilakukan analisis untuk mengetahui kualitas dari instrumen yang telah disusun. Metode yang digunakan pada penelitian ini adalah penelitian pengembangan dengan desain penelitian model ADDIE (Analysis, Design, Development, Implementation and Evaluation). Teknik pengumpulan data menggunakan metode angket validasi, metode tes diagnostik berformat four-tier dan metode wawancara sebagai data pendukung. Data pada penelitian berupa validitas logis dan empiris instrumen tes diagnostik dan wawancara peserta didik. Penelitian ini diuji cobakan kepada 50 peserta didik kelas XII MIA 2 dan MIA 3 di SMA Muhammadiyah 10 GKB Gresik dan diterapkan kepada 26 peserta didik kelas XII MIA I di SMA Muhammadiyah 10 GKB Gresik.

Abstract

In the learning process at school, students often experience misconceptions even though these concepts have been taught previously. One of the causes of misconceptions that occur among students comes from the students themselves. Students experience misconceptions, especially regarding abstract concepts such as Newton's Laws. Therefore, to diagnose students' misconceptions regarding Newton's Law material, a four-tier diagnostic test instrument was developed. Apart from that, analysis was carried out to determine the quality of the instruments that had been prepared. The method used in this research is development research with the ADDIE model research design (Analysis, Design, Development, Implementation and Evaluation). The data collection technique uses a validation questionnaire method, a four-tier diagnostic test method and an interview method as supporting data. The data in the research are in the form of logical and empirical validity of diagnostic test instruments and student interviews. This research was tested on 50 students in class XII MIA 2 and MIA 3 at SMA Muhammadiyah 10 GKB Gresik and applied to 26 students in class XII MIA I at SMA Muhammadiyah 10 GKB Gresik. The logical validity results show that the four-tier format diagnostic test instrument developed meets the very valid criteria with a Percentage of Agreement (PoA) of 93% for the content domain, 94% for the construction domain, and 100% for the language domain. The empirical content validity results for the FP category obtained a percentage of 7.8%, while the FN category obtained a percentage of 7.6% which met the requirements for FP and FN <10%. The results of the empirical construct validity of the 15 questions developed showed that 12 questions were declared valid with a reliability coefficient of 0.788, declared reliable in the high category. The misconception profile of class XII MIA 1 students at SMA Muhammadiyah 10 GKB Gresik shows that students experience misconceptions in all Newton's Law sub-materials. The causes of misconceptions identified in this research are: associative thinking at 37%, humanistic thinking at 3%, preconceptions at 38%, wrong reasoning at 17%, and wrong intuition at 5%.

Validity of the Stilts Local Wisdom-Based Physics Website for Training High School Students' Scientific Literacy

Riza Azizah Pratami — 2024-03-09

Abstract

Education today requires skills in learning, not just knowledge. One of the skills that students must have is scientific literacy skills with three aspects, namely explaining scientific phenomena, teaching and designing discussions scientifically, and interpreting data scientifically. Current educational developments go hand in hand with technological developments. The rapid development of technology means that many students are starting to forget local wisdom such as traditional games that were often played in the past. So the physics website development research that has been carried out aims to produce a website with the local wisdom of the traditional stilt game to train students' scientific literacy skills with material on the balance of rigid bodies that is valid for use in learning. This research is a type of development research using the Waterfall model with four stages used, namely Analysis, Design, Implementation, and Testing. Data collection techniques for website validity are reviewed from the language, media and material aspects. The research results showed that the percentage of validity of web-kalisa in the stilt game to train scientific literacy skills in the media aspect was 93.18%, in the material aspect it was 94.64%, and the language aspect obtained a score of 93.75%. The average validity score obtained was 93.86% in the very valid category. In this way, the resulting physics website based on local stilt wisdom is valid for use to train students' scientific literacy skills.
