Analysis of Student’s Difficulties in Solving Physics Problem: Impulse and Momentum Topics

Physics education essentially intends to cultivate student’s analytical and reasoning capabilities. However, this objective is hard to achieve because there are many students who facing difficulties in solving physics problems. This research was conducted to identify the types of student’s difficulties in solving momentum and impulse problems, along with the factors causing it. This research was conducted using a descriptive qualitative approach to 66 students of Senior High School 2 Makassar who had studied momentum and impulse topics. The data collection process was carried out using test and interviews. Based on the results, it can be identified that there are two types of student’s difficulties in solving momentum and impulse problems. The first type was physical difficulties which consisted of student’s difficulty in understanding the questions (26%) and student’s difficulty in determining the useable equations (25%). Then, the second type was mathematical difficulties which consisted of student’s difficulty in substituting the data to the equation (63%) and student’s difficulty in performing mathematical operations (76%). Based on interviews and analysis, it can be concluded that these difficulties was commonly faced by students while solving physics problems, including in momentum and impulse topic. Futhermore, the difiiculties were caused by several factors, namely: 1) the lack of student’s understanding about physics concepts, 2) the weakness of student’s mathematical skills, 3) the lack of physics learning process which is not honing student’s problem-solving skills and 4) the lack of student’s motivation on developing their problems solving skills in physics subjects. Thus, researchers recommend to all physics teachers in Indonesia to immediately develop or implement learning strategies or methods which are considered capable of overcome all student’s difficulties that have been found.

The search was limited to peer-reviewed journal articles written in English and whose full papers were available on the databases. Additionally, the articles were published between 1987 and 2018 because SPS's teaching and learning has been prevalent in research since the early 1980s. In total, 198 articles were found as a result of the initial search. The researcher screened abstracts of these articles to judge their relevance, and from this screening process of abstracts, 40 papers have been included for review. Reviewed study trends on SPS development conducted from developed and developing countries focusing on three vantage points: science curriculum, teacher education and the 21st Century Learning. Based on the findings, more research studies on SPS in science education are carried out in developed countries than developing ones. The review findings indicate uneven inclusion of SPS in the science curriculum documents and the curriculum implementation at all science education levels. Lastly, results display few studies on SPS education regarding 21st Century Learning conducted in developed and developing countries. Concerned education bodies must take appropriate and reasonable exploits on teacher training of SPS education and the balanced inclusion of SPS in the science curriculum and its implementation into consideration. SPS still champions the development of other skills individuals are supposed to possess in this 21st-century era. Hence, SPS education in science education remains a need for both developed and developing countries.
