Abstract

The aim of this research is to find out the causes of misconceptions experienced by students when solving word problems in FPB and KPK learning materials. The research subjects were fourth grade students at SDN Pasir Gadung, Serang City. The methods used are: questionnaire, test, interviews, and documentation. The written exam was carried out by 38 class IV students at SDN Pasir Gadung. After the data is valid and the location of the misconception is known, further research is carried out involving interviews until the source of the misconception is identified. The research results showed that 43.02% of students experienced conceptual misconceptions, namely not being able to understand the concepts of FPB or KPK when solving story problems on FPB and KPK material. Systematic Misconceptions As many as 25.58% of students experienced missteps when completing story questions on FPB and KPK material. The calculated misconception is 24.42%. Students experience misconceptions about arithmetic when solving word problems in FPB and KPK learning materials. Misconceptions arise due to errors in the calculations made, especially when answering the FPB or KPK results or when determining the final results obtained. Operational misconceptions as many as 6.98% of students experienced errors when using the applied operations. The causes of misunderstanding lie in students and teaching methods. The cause of misconceptions among students is likely caused by students' associative thinking and students' low interest in learning. The cause of misunderstanding regarding teaching methods is because learning media is not utilized.
