The Higher-Order Thinking Skill Test Instrument on Quadratic Equations (HOTS-QE) was developed to measure the level of HOTS on the topic of quadratic equations among secondary school students. The HOTS-QE instrument consists of 17 structured subjective items divided into two smaller questions according to the three levels of HOTS, namely applying, analysing, and evaluating. This study proposes a design and development research (DDR) approach via a development research that was done through an organised and systematic process. The DDR-oriented development process comprised seven stages namely source analysis, theory, development, content validity, validation of the HOTS domain accuracy, language validity, and pilot study. The development of the HOTS-QE instrument comprised seven stages, namely source analysis, theory, development, content validity, validation of the HOTS domain accuracy, language validity, and pilot study. The content validity of the instrument was evaluated by five mathematics education experts. The results showed that the item content validity index (I-CVI) value of each item was above 0.70 while the content validation per scale (S-CVI) value was 0.98. Results from the interrater evaluation also showed that the HOTS level accuracy of the instrument items had achieved the Cohen's Kappa coefficient value of 0.63. In addition, findings from the pilot study also showed that the Cronbach's alpha coefficient value was 0.79, the discrimination index value of each item was between 31.11% to 66.67%, and the difficulty index values were between 40.74% to 70.00%. These results suggest that the HOTS-QE instrument has an acceptable level of validity. The development of this instrument provides a more varied learning assessment that can foster students' interests in learning, help them to improve HOTS, and provide opportunities for students to directly apply the knowledge of quadratic equations learned at school in their daily life.

“…In that case, they have been through information processing, memorising, or interpreting, leading to an incorrect understanding of the concept. For example, students cannot distinguish between quadratic expressions and quadratic functions (Utami & Jupri, 2021). The teachers did not provide opportunities for the students to connect the idea of functions and quadratic equations in one variable in level four in the context of daily life because students acted as the primary audience for the emphases on mathematical relationships in the classroom.…”

This study aims to identify the impact of GeoGebra software on conceptual understanding and engagement in the topic of Functions and Quadratic Equations in One Variable in high school. The study was conducted in a quasi-experimental design with 60 students at a secondary school in Muallim district. The study results were analyzed using descriptive statistics, inference, and the Pearson Correlation. Descriptive analysis indicates that students have a strong grasp of the topic taught, particularly showing high conceptual understanding and maximum engagement in interactive activities. Inference statistics reveal a significant difference in conceptual understanding levels between the treatment and control groups among Level Four students regarding Quadratic Functions and Equations in a Variable. In addition, there were significant differences in student engagement between the treatment and control groups. There is a significant relationship between the level of student engagement and students’ conceptual understanding of Quadratic Functions and Equations in One Variable for both groups. In conclusion, using GeoGebra software has an impact on the relationship between understanding the concept and involving students in learning the topic of Quadratic Functions and Equations in a Variable.

In learning algebra, one of the skills needed to be acquired by students is solving equations, such as linear equations in one variable and quadratic equations. This study aims to analyze the symbol sense ability of students by investigating strategies used to solve algebraic equations that consist of linear, quadratic, and rational equations. A qualitative descriptive method was conducted. The instrument included a test with one linear equation, one quadratic equation, and three rational equations (involving linear or quadratic factors). The test was administered to 12 students from 12th-grade high school in Bandung. Each student was asked to solve it in two different ways of answers if possible. The results showed that students were able to use symbol sense strategies for solving problems. However, there were still mistakes in solving algebraic squared value concepts, affecting their final results of the answers. We conclude that even if students can use their symbol sense abilities properly, they need to pay attention to their mathematics concepts.
