Abstract

The effectiveness of learning is affected by the assistance stages (scaffolding) provided. For example, the scaffolding of type 2a and type 2b supports the causal-thinking approach in learning. The type 2a informs the causal model, number of causes and effect, while 2b informs its argument sample. This research aimed to identify the effect of causal thinking process (CTP) with scaffolding type 2a and 2b on optics problem-solving ability (PSA) of students. The type of the research was quasi-experiment with the non-equivalent-group design. Data were obtained with PSA-test and analyzed with the two-tail test with separated variance formula at significance degree of 5% to determine the effect of each type of the CTP on the PSA, also to determine its difference. The results showed that tcount for each of the first two t-tests were greater than ttable, but tcount for the third one was smaller than its ttable. This research concluded that the implementation of the CTP with the scaffolding of type-2a and 2b were effective to improve the student’s PSA. However, the improvements were not different.Efektivitas pembelajaran dipengaruhi bantuan tahapan (scaffolding) yang diberikan. Dengan pendekatan berpikir kausalitik ini, diperkenalkan scaffolding tipe-2a dan tipe-2b. Kedua scaffolding ini menginformasikan model kausal serta jumlah Cause dan Effect tetapi pada tipe-2b ditambah contoh argumentasinya. Penelitian ini bertujuan mengidentifikasi pengaruh proses-berpikir-kausalitik (PBK) ber-scaffolding tipe-2a dan tipe-2b terhadap kemampuan-pemecahan-masalah (KPM) optik siswa. Jenis penelitian kuasi-eksperimen dengan desain non-equivalent-group. Data diambil menggunakan alat tes-KPM dan dianalisis dengan uji-t dua pihak menggunakan rumus separated varians pada signifikansi 5% untuk mengetahui pengaruh PBK tipe-2a dan 2b terhadap KPM, serta perbedaan kedua pengaruh tersebut. Hasil menunjukkan nilai thitung untuk dua uji-t pertama lebih besar dari tTable terkait tetapi nilai thitung untuk uji ketiga adalah lebih kecil dari tTable-nya. Simpulan penelitian implementasi PBK ber-scaffolding tipe-2a dan 2b masing-masing berpengaruh terhadap peningkatan KPM siswa tetapi kedua pengaruh tersebut tidak berbeda.

Abstract

Critical thinking has become a major competency of higher education learning in Indonesia; therefore, a specific learning model that is oriented towards improving students' critical thinking skills is important to be developed. This study aims to develop an Inquiry Creative Process (ICP) learning model to promote critical thinking skills of physics prospective teachers. This research is the first step of development research which produce learning model with valid criteria on content validity and construct validity aspects. The validation of ICP learning model has been done through focus group discussion (FGD) mechanism involving 5 experts as validator. The data of the validation results of the model were analyzed descriptively by averaging the validation score. Validation results show that the validity level (Va) of 4.12. The conceptual framework and validation results of the ICP learning model are described in this article.Berpikir kritis telah menjadi kompetensi utama pembelajaran tingkat pendidikan tinggi di Indonesia, sehingga model pembelajaran yang spesifik berorientasi ke arah peningkatan keterampilan berpikir kritis mahasiswa menjadi penting untuk dikembangkan. Penelitian ini bertujuan mengembangkan model pembelajaran Inquiry Creative Process (ICP) untuk melatih keterampilan berpikir kritis mahasiswa calon guru fisika. Penelitian ini merupakan langkah awal penelitian pengembangan yang menghasilkan produk model pembelajaran dengan kriteria valid pada aspek-aspek validitas isi (content validity) dan validitas konstruk (construct validity). Validasi model pembelajaran ICP dilakukan melalui mekanisme focus group discussion (FGD) dengan melibatkan 5 orang pakar selaku validator. Data hasil validasi model dianalisis secara deskriptif dengan merata-rata skor hasil validasi. Hasil validasi menunjukkan tingkat kevalidan (Va) model pembelajaran ICP sebesar 4,12 berada pada kategori valid. Kerangka konseptual dan hasil validasi model pembelajaran ICP dijabarkan dalam artikel ini.
