Implementasi Model Pembelajaran Contextual Teaching and Learning Dipadukan Dengan Game Based Learning Untuk Meningkatkan Pemahaman Konsep Siswa

Implementation of Contextual Teaching and Learning Models Combined with Game Based Learning to Improve Students' Understanding of Concept

Pemahaman konsep adalah tingkat kemampuan yang mengharapkan siswa mampu memahami konsep, situasi dan fakta yang diketahui, serta dapat menjelaskan dengan kata-kata sendiri sesuai dengan/pengetahuan yang dimilikinya, dengan tidak mengubah artinya. Pemahaman konsep sangatlah penting dalam mata pelajaran IPA, karena untuk memaksimalkan pengetahuan dan pemahaman konsep IPA. Pendidikan IPA hendaknya menghantarkan siswa untuk dapat menguasai konsep-konsep IPA, serta tidak hanya membiarkan siswa mengingat ataupun menumpuk informasi tanpa memahami maksud dari informasi tersebut. Penelitian ini bertujuan untuk mengetahui peningkatan pemahaman konsep siswa, mendeskripsikan keterlaksanaan proses pembelajaran, serta respons siswa terhadap model Contextual Teaching And Learning dipadukan dengan Game Based Learning. Desain yang digunakan adalah one group pretest dan posttest dengan partisipan sebanyak 31 siswa kelas VIII-C di salah satu SMP di Kabupaten Jombang. Teknik pengumpulan data yang digunakan, yaitu tes tulis, observasi serta survei respons siswa. Data yang telah terkumpul kemudian dianalisis menggunakan uji analisis inferensial, normalized gain, visualisasi scatterplot, Kappa-Cohens, serta persentase angket respons. Hasil dari penelitian ini diperoleh bahwa peningkatan pemahaman konsep dari seluruh indikator memperoleh rata-rata 0,72 dengan kriteria tinggi. Penyebaran plot skor pretest terhadap <g> pada dua orang siswa yang bisa mencapai nilai <g> maksimal, saat skor pretest rendah. Hal ini menggambarkan bahwa model Contextual Teaching and Learning dipadukan dengan Game Based Learning dapat berpotensi memberikan dampak positif terhadap pemahaman konsep siswa. Keterlaksanaan proses pembelajaran terlaksana dengan kategori sangat baik dan memperoleh kesepakatan perfect agreement. Aktivitas siswa yang teramati dianggap bahwa pengajarannya hampir merata dan aktif, hal yang teramati adalah melakukan percobaan, berdiskusi serta bermain menggunakan platform wordwall. Respons siswa menunjukkan bahwa model Contextual Teaching and Learning dipadukan dengan Game Based Learning dapat memberikan motivasi sehingga bisa berdampak positif terhadap pemahaman konsep siswa.

Understanding the concept is the level of ability that expects students to be able to understand concepts, situations and known facts, and be able to explain in their own words according to their knowledge without changing the meaning. Understanding concepts is very important in science subjects, because to maximize knowledge and understanding of science concepts. Science education should lead students to be able to master science concepts, and not just let students remember or accumulate information without understanding the purpose of the information. This study aims to determine the increase in students' understanding of concepts, describe the implementation of the learning process, and students' responses to the model Contextual Teaching and Learning combined with Game Based Learning. The design used was one group pretest and posttest with 31 class VIII-C students participating in one of the junior high schools in Jombang. The data collection techniques used were written tests, observations and students’ response surveys. The data that has been collected is then analyzed using an inferential analysis test normalized gain, visualization scatterplot, Kappa-Cohens, as well as the percentage of response questionnaires. The results of this study showed that the increase in conceptual understanding of all indicators obtained an average of 0.72 with high criteria. Score plot spread pretest against in two students who can achieve a value of maximum, when the pretest score is low. This illustrates that the model Contextual Teaching and Learning combined with Game Based Learning can potentially have a positive impact on students' understanding of concepts. The implementation of the learning process was carried out in a very good category and obtained an perfect agreement. Observed students’ activity is considered that the teaching is almost evenly distributed and active, what is observed is conducting experiments, discussing and playing using platforms wordwall. Students’ responses indicate that the model Contextual Teaching and Learning combined with Game Based Learning can provide motivation so that it can have a positive impact on students' understanding of concepts.
