The Effect of Presenting Anomalous Data on Improving Student’s Critical Thinking Ability

Abstract

This study aim to explore the effects of presenting anomalous data on improving student’s critical thinking ability. This study is an experimental research conducting on one-group pretest-posttest design. Purposive sampling was used in this study, where one class group was used as a sample of the study, namely 36 students of senior high school at MA Hidayaturrahmah NW Menggala, North Lombok, West Nusa Tenggara, Indonesia. The data of CT ability collected by instrument refer to Ennis-Weir Critical Thinking Essay Test. The data analysis descriptively and statistically were done to process the data of research. Path analysis was used to evaluate the contribution of presenting anomalous data on improving student’s critical thinking ability. The results of this study indicate that the presenting anomalous data at initial learning have an effect and contribute on improving student’s critical thinking ability. Further reviews are described in this article.

QASEE: A Potential Learning Model to Improve the Critical Thinking Skills of Pre-service Teachers with Different Academic Abilities

“…However, based on the corrected mean scores, the QASEE learning model has the most potential in upgrading the preservice teachers' critical thinking skills, and then followed by the RQA learning model. This finding is in line with the research results by (Amin et al, 2020;Ichsan et al, 2019;Kwan & Wong, 2015;Mahanal et al, 2019;Prayogi et al, 2019;Sari et al, 2019;Zubaidah et al, 2018) who reported that critical thinking skills could be trained by conditioning individuals in constructivist-based learning environments through the implementation of certain learning models.…”

“…The problems with critical thinking skills and the difference in pre-service teachers' academic ability can be overcome by applying constructivism-based learning (Kusaeri & Aditomo, 2019;Mahanal et al, 2019;Prayogi et al, 2019;Vong & Kaewurai, 2017;Zubaidah et al, 2018). Two constructivism-based learning models believed having potential to improve pre-service teachers' critical thinking skills are the RQA and QASEE learning models.…”

Prospective Science-Teachers’ Services Satisfaction: an Exploratory Studies in Private Education Institutions in Indonesia

“…These findings indicate that knowledge about university functions, skills and service attitudes of administrative staff play a very important role in increasing student satisfaction. Service has an impact on many aspects, especially creating a good academic atmosphere, because global demands expect students to not only be able to study well but develop their thinking according to the demands of the 21 st century (Prayogi, Yuanita, & Wasis, 2018;Prayogi, et. al., 2019).…”

Effect of Inquiry Creative Process Learning Models on Improving the Critical Thinking Ability of Prospective Science Teachers

“…The number of questions as many as 8 (eight) items follow the indicator of critical thinking ability, so the maximum score is +24 and the minimum score is -8. The conversion of scores into categorized qualitative data adapted from Prayogi, et. al.…”

“…One of the factors that causes the low quality of learning is the learning process that does not encourage students to think critically. Critical thinking has become a major trend and focus in learning, even curriculum authorities in some developed countries have included the critical thinking ability in their curriculum as a learning objective and one of the essential skills in the 21 st century (Prayogi, Yuanita, & Wasis, 2017;Prayogi, et. al., 2019).…”
