Abstract

Research shows that female students are generally more susceptible to mathematics anxiety than male students, although some studies have found similar or higher levels of anxiety among males in certain contexts. The research gap lies in the need for further exploration of how the interaction between gender and geographical location influences the level of mathematics anxiety. This study aims to analyze the level of mathematical anxiety among junior high school students in Makassar and Malang, focusing on various aspects of mathematics anxiety and comparing these levels based on gender. The research method employed is a quantitative descriptive approach, involving 86 students from junior high schools in both cities. The instruments used include a mathematical anxiety identification test and a questionnaire that measures the four main aspects of anxiety. The results indicate that, overall, the mathematical anxiety of students in both cities falls within the moderate category across all analyzed aspects. Female students tend to experience higher levels of anxiety compared to male students, particularly in Malang, while in Makassar, male students exhibit slightly higher mathematical anxiety in several categories. This study highlights the need for self-regulated learning to reduce mathematics anxiety in both male and female students.

Abstract

Intervention model analysis is a statistical technique used to assess the impact of an intervention event, caused by internal or external factors, on a time series dataset. The primary goal of this analysis is to quantify the magnitude and duration of the effects on the time series. Intervention models are typically divided into two types: the step function and the pulse function. The step function represents an intervention event with a long-term influence, while the pulse function captures the effects of an intervention within a specific time span. This study examines the stock price data of BBRI from March 2017 to June 2020, with the intervention point identified as the onset of COVID-19 in Indonesia, specifically during the first week of March (t = 155). ARIMA modeling was applied to pre-intervention data to determine the order of intervention (b, s, r). The analysis concluded that the best-fitting model was ARIMA (2, 1, 0), with the intervention order characterized by a step function where b = 0, s = 2, and r = 0. The accuracy of the forecasting results was evaluated using the Mean Absolute Percentage Error (MAPE), which yielded a value of 8.48%.

Abstract

Problem solving is one of the abilities that students must have in the 21st century. This is because students' ability to solve problems is expected to increase their higher order thinking skills (HOTS) competency. The ability to measure problem solving can be assessed through test instruments in the form of questions containing problems. This research aims to analyze problem solving abilities in colloidal materials through the development of the IDEAL Problem Solving assessment instrument. This instrument includes five indicators, namely Identify the Problem, Define the Outcome, Explore Possible Strategies, Anticipate Outcome & Act, and Look back and Learn. The research was conducted for 3 months at SMAN 1 Sungai Tabuk class XI semester II (even). The method used is development research or R&D (Research and Development) research. The development of this instrument adapts the ADDIE development model by following five steps, including (1) Analyze (analysis), (2) Design (planning), (3) Develop (development), (4) Implementation (implementation), (5) Evaluate (evaluation). Data analysis was carried out quantitatively with statistical tests. The empirical validity results show that the instrument is valid and reliable to use and meets the criteria for a good level of difficulty and discrimination.
