The Analysis of Students' Difficulties in Solving Problems of Probability for 8th Grade

Abstract

Probability is one part of mathematics material that is learned in school. In Indonesia, probability is learned from Junior High School level and is continued in Senior High School level. Hence, understanding of probability's concept in Junior High School level is very important. The aim of this research is to analyze students' difficulties of 8 th Grade of SMPN 1 Prambanan Klaten in solving problems of probability. The method used in this research is descriptive method. Data collection was done based on students' work through essay test. The result shows that the difficulties which are experienced by the students in solving pobability's problem are the difficulty in understanding proportional reasoning and the difficulty in resolving misconceptions or misperceptions in probability. The misconceptions are representativeness, probability cannot be measured mathematically, misuse or extend conclusions inappropriately, inappropriate reasons, beliefs, equi-probability bias, and possible means certain.

Flip the Tin Can Game with a Twist: Effects on the Achievement Levels of Grade 8 Learners in Probability

“…According to Arum, Kausmayadi, & Pramudya (2018), the common misunderstandings about probabilistic concepts and the challenge of using the word or probability term in mathematical contexts contribute to the difficulty experienced by the learners. Anggraini & Kusrini (2018) concluded in their study that learners are having difficulties solving probabilities because of difficulty understanding proportional reasoning and resolving misconceptions or misperceptions of probability. Therefore, there has to be some kind of effective solution to help the learners comprehend the fundamentals of probability and to keep the learners engaged in the process of acquiring this knowledge.…”
