| dc.description.abstract | Developing critical and collaborative thinking skills among learners was of significant importance
in the 21st-century era. In this study, the researcher applied teaching and learning based on
Research-Based Learning (RBL) to know the level of students critical thinking skill. The number of
research samples was 30 students. This study used a triangulation research method, namely a
combination of qualitative and quantitative methods. The quantitative method was obtained by
using a learning outcome test and the qualitative method is obtained using a questionnaire and
interview. Then the data that has been collected was analyzed using a t-test. Four students were
chosen to represent critical thinking level 4, 13 students were chosen to represent Critical Thinking
level 3, and 6 students were chosen to represent critical thinking level 2, 4 students were chosen to
represent critical thinking level 1, and 3 students were chosen to represent critical thinking level 0.
More subjects would be involved until the data was saturated. Students on low critical thinking
were at Level 0. Based on the interpretation result of the t-test value, there was a significant
difference between the control class and the experimental class, proved by the 0.000 figure in the
statistical analysis. Therefore, it proved a significant difference in learning outcomes. However, the
data that we obtained present a significant difference between the control class and the
experimental class below 0.05. After we interpreted t-tabel = 2.04 on degrees of freedom 0.025, tcount of 0.000 was evident. Thus, a hypothesis was accepted since it was below 0.025. Qualitative
methods show the results of interviews with 2 students. | en_US |
