The findings indicated that there were few variations between male and female students' CTA. Data analysis used descriptive statistics assisted by the Rash model. Identification was made by giving the sampled students a questionnaire to find their learning styles. Data were collected on student’s CTA using a description of five numbers. 75 kids from Mataram's junior high schools participated in this study. This study has a group post-test only design and is a quasi-experimental investigation. Descriptive quantitative research is the term for this kind of study.

This study uses the online learning environment Edmodo to analyse student CTA in terms of gender and learning style. Many things that were not thought of before suddenly appear and become innovations, including in education. The Industrial Revolution 4.0 is synonymous by the Internet development its presence is so fast. , (4) item reability is a matter of 0.71 (Reliable good category), (4) the ability of students is low as 0.12 means that the HOTS students are low. In this research, HOTS description of students is produced, namely: (1) HOTS students at the highest ability are owned by LD02 (measure = +2.56 logit) to the lowest ability possessed by LD09 (measure = -2.42) with a standard level of difficulty of the problem with a logit value of 0.48 (2) most students experience difficulties when formulating the physics equation and the calculation process (3) analyzing is the ability that is most dominated by students with logit values in a row of - 0.71 and -0.67 followed by creative ability with logit values of -0.12 and -, 028, respectively, the ability to evaluate with logit values of 0.00, 0.95 and 0.82, respectively. Through this research will be obtained the exposure of HOTS data of Singkawang STKIP physics education students on wave and optical material so that it is expected to be the basis for further research. Validity and reliability tests in this study will use rasch modeling with the help of Winsteps software. This research is quantitative descriptive. This study aims to determine the Descriptions of Student Higher Order Thinking Skills (HOTS) of Singkawang STKIP physics education students.
