Abstract

Quadrilateral is one of the geometry topics in the curriculum, and students at junior high school must understand the topic. Therefore, we researched 40 students (11/13 years) in Kambera District, East Sumba Regency, East Nusa Tenggara, to identify and describe students' geometric thinking levels. The research is descriptive qualitative research with data collection techniques and is a written test for the quadrilateral case. The data were analyzed using van Hiele's theory. The results showed that 1) only one-third of the students are at level 0 (visualization), i.e., students knew geometric pictures by observing the images or models. At this level, half of the students still need to improve in classifying the types of quadrilaterals, and 2) only a few students are at level 1. They can understand or know the properties of quadrilaterals. The written results found that almost all students needed help understanding the topic of quadrilaterals and their properties well. Nearly all students have yet to be able to recognize and classify the types of quadrilaterals well.

Abstract

In creating educational objectives aligned with the Learning Compass 2030, it is essential to establish a learning environment where students feel comfortable and to apply learning strategies suited to the characteristics of the learners. The objective of this research is to map students' metacognitive skills to understand their learning strategies in solving science-related problems. This study employs a mixed-methods approach, which involves collecting both quantitative and qualitative data, integrating the two forms of data, and using diverse research designs. The quantitative data were obtained from administering metacognitive skills tests and questionnaires, while qualitative data were gathered from student interviews. The research yielded several findings: (1) expert validity results for the metacognitive skills instrument indicated it is valid, (2) trial testing of the instrument showed it to be reliable and valid, (3) the profile of students' metacognitive skills across all indicators was found to be low in three different schools, and (4) there was a high response rate. The novelty of this research lies in mapping students' metacognitive skills in three different regions after the COVID-19 pandemic.
