Abstract

This study aims to identify the ability of students to work on HOTS questions and calculate the level of students’ abilities based on Polya’s theory. The research was conducted at SMA Negeri 2 Sanggau with the research subject of 25 students who were given a test. This study used descriptive qualitative method. Data were collected by essay test and interview. The data analysis technique used is Miles and Huberman. The results showed that the average percentage of students' abilities in solving HOTS questions on momentum and impulse materials was 80.2%. The ability of students is divided into 4 according to Polya's theory (1) the ability to understand problems is 88.8% (2) the ability to make plans is 75.2% (3) the ability to carry out plans is 87.2% (4) the ability to re-examine is 69 ,6%.

Abstract

This research is intended to detect the misconception about parabolic motion of the tenth grade students of SMA N 6 Pontianak. The test items are adapted from the diagnostic tests which have been developed and have also met the required criteria of Lila (2017). There are 24 items of diagnostic tests. The research simple consists of 36 students which are the tenth grade students of SMA N 6 Pontianak. The result shows that 58,33% students stated that the maximum speed is when an object is on the top; 27,78% students stated that the minimum speed is on the farthest point; 30,56% students stated that the smallest the elevation angle the more time is needed; 91,67% students stated that the largest the elevation angle the farthest an object can reach; 63,89% students stated that the speed of axis x is different from the initial speed; 75% students stated that the time need will be different when two object are dropped together on different tracks; 63,89% students stated that an object dropped at a certain height will form parabolic motion track which was seen by observer as a pilot; 55,56% students stated that an object dropped at a certain height will form a backward parabolic motion track seen by observer from the ground. Hopefully the findings of this research will be used as additional reference when choosing the right treatment to solve the misconception.

Abstract

This research aims to determine the effect of the learning cycle 7E model assisted by PhET Simulation in reducing misconception on fluid material at SMA Negeri 2 Simpang Hulu. The form of this research uses Pre-Experimental Design in One-Group Pre-Test Post-Test Design. The participant of this research is about 27 students of XI class. A multiple-choice diagnostic test with reasons was used to determine the average students' misconceptions. From the results of data analysis, the average percentage of students' misconceptions before remediation was 55,27% and the average percentage of students' misconceptions after remediation was 17,92%. Based on McNemar's test for df=1 and α=5%, the χ^2 table is 3,841. The average value is displayed in the calculation of χ^2 count at 8,667. Because χ^2 table <χ^2 count then H0 is rejected in other words Ha is accepted, meaning that there is a significant change in students' conceptions of all indicators in static fluid material after being given remediation activities using a learning cycle model assisted by PhET Simulation. In students' misconceptions remediating, the learning cycle model can be used as an appropriate learning model. Because the learning cycle 7E model consists of organized phases so that students' understanding is well-constructed and provides encouragement for students to experience directly, independently, and have an active role in trying to understand the material being taught.
