Analysis of Students’ Misconceptions on Solving Algebraic Contextual Problem

Students misconceptions in solving contextual algebraic problems is still often found in this educational world. This study aims to describe the forms of student’s misconceptions in solving algebraic contextual problems and explain the causes of these misconceptions. The approach in this research is a qualitative approach, that is library research where the data used are secondary data. This research uses literature review data collection techniques. The number of articles used as data sources is 19 articles related to topics in research with algebraic contextual items taken from 5 articles to be displayed in the results section of the study. Data analysis used descriptive analysis method by describing the intentions and comparing several research articles. The results showed several forms related to non-systematic errors, namely concept errors or students’ misconceptions in solving algebraic contextual problems, namely the occurrence of misconceptions within the scope of algebraic arithmetic operations, understanding the meaning of variables, simplifying, or operating algebraic expressions, and interpreting contextual problems into algebraic mathematical form. The misconception occurs in students with low and moderate mathematical abilities where the cause of this phenomenon is due to the occurrence of errors in the learning process by educators in which students are less accustomed to solving contextual problems or open-ended questions. Therefore, it is hoped that educators can determine the learning model appropriately in fixing the problem of contextual algebraic misconceptions and further researchers can find new learning models that affect this problem.

Konstruksi Sosial Atas Pemaknaan Dan Simbol Kecantikkan Pada Trending Hastag Tik Tok

Reality is only a social construction created by humans. Tik Tok is a new reality phenomenon constructed by the community as a form of self-expression. One of the features offered by Tik Tok is trending hashtag, which is a collection of the most popular videos. The number of Tik Tok users, especially women, are competing to create content related to the meaning of beauty. This study seeks to analyze the social construction of the meaning of the symbol of beauty in the trending hashtag Tik Tok. The samples of this study were 4 trending hashtags, namely: ladadida challenge, negligee challenge, dualism challenge and ah steady challenge. By using the Zhongdang Pan and Gerald M. Kosicki's framing analysis, the results show that there are beauty constructs from these 4 challenges. The symbol of beauty on Tik Tok proves that those users with beautiful faces, white, make up, and wear good clothes are those who are popular and get a lot of attention from other users. The results of this study are expected to be able to be used as literacy for the younger generation, especially Tik Tok social media users, to be wiser in constructing beauty, that everyone is basically beautiful and has different standards of beauty.
