This study aims to analyze junior high school students’ critical thinking skills in solving problems related to Systems of Linear Equations in Two Variables (SPLDV). The research employed a descriptive qualitative approach and was conducted at SMP Negeri 9 Kota Jambi involving 32 ninth-grade students. Data were collected through contextual essay-type SPLDV tests designed based on six critical thinking indicators proposed by Facione, namely interpretation, analysis, evaluation, inference, explanation, and self-regulation. In-depth interviews were also conducted to support and clarify the test results. Data analysis followed an interactive model consisting of data reduction, data display, and conclusion drawing. The findings indicate that students’ critical thinking skills have not developed evenly across all indicators. Interpretation skills were relatively better developed, while evaluation, inference, explanation, and self-regulation remained at low levels. Most students were able to identify relevant information and construct mathematical models; however, they experienced difficulties in evaluating solution procedures and drawing logical conclusions. These results highlight the need for mathematics learning strategies that emphasize analytical reasoning, evaluation, and reflective thinking to enhance students’ critical thinking skills, particularly in learning SPLDV.

The main objective of this study is to identify and explain students’ errors in solving PISA questions on Space and Shape content using Newman’s Error Analysis. The errors analyzed include five categories: reading errors, comprehension errors, transformation errors, process skill errors, and encoding errors. This study employs a descriptive qualitative approach with data collected through tests and interviews. The research subjects are ninth-grade students at SMP Negeri 7 Muaro Jambi. The results show that students frequently made errors in the stages of understanding the questions, modelling the questions into mathematical forms, and process skills. These errors were by weaknesses in processing information, limited mathematical skills in real-life contexts, and a lack of experience in practicing PISA questions. These findings highlight the importance of familiarizing students with contextual problems as an effort to minimize errors in solving PISA questions.

Statistical literacy is a critical 21st-century competency, as students increasingly encounter data-driven information in their everyday lives. However, international assessments such as PISA consistently show that Indonesian students struggle to interpret and reason with data. This study aims to investigate junior high school (JHS) students’ statistical literacy in solving PISA-based problems related to uncertainty and data, while also linking the results to Sustainable Development Goal (SDG) 4: Quality Education. A descriptive qualitative approach was employed involving 40 ninth-grade students from JHS Negeri 6 Kota Jambi, selected through purposive sampling to represent high, medium, and low academic ability groups. Data were collected through a validated PISA 2012 item focusing on uncertainty and data, along with semi-structured interviews designed to explore students’ statistical-literacy strategies. Data analysis followed an interactive model consisting of data reduction, data display, and conclusion drawing, guided by Schield’s (2011) statistical-literacy indicators. The findings indicate that only 17.5% of students demonstrated a high level of statistical literacy, while most were categorized as medium (37.5%) or low (45%). Further analysis revealed persistent difficulties in identifying trends, calculating averages, and drawing valid conclusions. These findings underscore the need for contextual, PISA-based learning tasks that foster statistical reasoning and strengthen students’ fundamental literacy skills as a foundation for achieving quality education.

Several previous studies have widely discussed students’ mathematical literacy; however, research that specifically analyzes junior high school students’ mathematical literacy in the topic of Linear Equations in One Variable through contextual problems remains limited. Therefore, this study aims to describe the mathematical literacy abilities of junior high school students in solving contextual problems related to the System of Linear Equations in One Variable. This study employed a qualitative research method involving 33 eighth-grade students of class VIII-I at SMP Negeri 6 Kota Jambi with diverse ability levels. The research instruments consisted of contextual essay tests, interviews, and documentation of students’ written responses. The test items were validated by experts and designed to reflect real-life situations. The results indicate that students’ mathematical literacy skills are generally low, with the majority of students classified in the low category. Students experienced difficulties in understanding information presented in the problems, formulating mathematical models, and interpreting as well as concluding the solutions. Analysis based on mathematical literacy indicators shows that only a small proportion of students were able to fulfill all three indicators comprehensively. These findings suggest that students have not yet met the demands of solving contextual problems mathematically. The results of this study may serve as a basis for developing more contextual and applicative mathematics literacy–based learning to improve the quality of mathematics education at the junior high school level.

This study developed PISA-like tasks in the Uncertainty and Data domain using climate change contexts and examined their potential to elicit junior high school students' statistical literacy. The study employed a design research methodology of the development studies type, in which Tessmer's formative evaluation model was applied specifically to the formative evaluation stage, encompassing self-evaluation, expert review, one-to-one, small group, and field test, alongside a preliminary phase and an assessment phase. A total of 49 Grade IX students from a state junior high school in Jambi, Indonesia, participated across the evaluation stages: three in one-to-one, nine in small group, and 37 in the field test. Twenty-two climate change–related tasks were developed. However, this article specifically focuses on one scenario concerning “Jakarta is Singking” due to climate change impacts. Data were collected through expert validation, student practicality questionnaires, written task responses, and interviews, and were analyzed qualitatively and descriptively. The developed tasks were valid in terms of content, construct, and language, and practical based on students' practicality scores. The assessment phase revealed a positive potential effect: Problem Understanding reached 76.06%, Data Processing 69.26%, and Data Interpretation 68.69%, all in the moderate category, with interpretation being the least developed due to students' limited prior exposure to context-rich tasks. The climate change context supported engagement with trends, variability, and uncertainty. These findings suggest that future studies should integrate climate-based PISA-like tasks within structured instructional phases to support the written expression of students' statistical reasoning, which in this study emerged more clearly through interviews than written responses.
