Abstract

This research aims to understand a phenomenon regarding high school students’ errors in solving mathematics problems using a qualitative approach with phenomenology as the analysis framework. Data were collected through tests, classroom observations, documentation (students’ answer sheets, list of attendees, and students’ score lists), and unstructured phenomenological interviews with four purposively selected participants who met the selection criteria. The researchers used the mathematical problem-solving (MPS) model by Rott-Specht-Knipping and Aguas’ phenomenological data analysis steps using the NVIVO 12 software to analyze the students’ MPS process and identify their errors and the factors contributing to these errors. Errors were predominantly found in problems solved without engaging in the exploration phase. Analysis errors were the most common, while errors due to carelessness were the rarest. Factors contributing to these errors were identified across five domains: MPS Ability (MPSA), cognition, affection, motivation, and self-awareness. This research provides valuable insights into student errors in MPS for researchers and educators, particularly teachers, and provides recommendations for mathematics education policies and future research.

Abstract

This research aims to detect Differential Item Functioning (DIF) in the 2014/2015 National Examination Questions in mathematics of junior high schools and equivalent-level schools in the Yogyakarta region as a reference group and the South Kalimantan region as a focus group using the Likelihood Ratio Test (LRT) method, Area Measure Raju, and Lord. A sensitivity analysis was conducted to determine the most sensitive method. The data consisted of 5,465 National Examination papers of the students from the two regions who worked on type A questions. A sample of 1,000 exam papers for each region was established using the simple random sampling (SRS) technique, which was conducted to avoid the effect of sample size. The research results showed that by using the LRT method, the researchers found 36 items had significant DIF detection, 32 items were significant for Raju Area, and all items had significant DIF detection using Lord. Lord Method is the most sensitive method because it can detect most DIF items.
