Abstract

The measure of spread is one of the concepts in Statistics that students find complicated. We have to use a specific formula or concept for a specific situation or contextual problem. As a result, people or students sometimes made mistakes or errors in solving statistics problems. Therefore, research to investigate errors made in solving problems involving a measure of spread is necessary. This study aims to describe students' errors in solving problems related to the measure of dispersion. Researchers used a qualitative descriptive approach. We administered the test during the even semester from January to June in the year 2021. The participants were 80 undergraduate students who have completed or taken statistics courses. This test consists of 2 questions that are related to each other. Researchers used the three main steps to analyze the data which consist of data condensation, data display, and verifying and drawing the conclusion. We obtained the data related to students' errors from their test results. The results showed that more than 50% of students still make mistakes on every problem. The mistakes made by participants consisted of the use of formulas, miscalculations, the use of known data, the use of concepts, not giving conclusions, and inconsistencies.

Abstract

The development of the covid-19 vaccine and the impact of online learning enable the government in Indonesia to remove some restrictions caused by the pandemic and our situation now is called the new normal. In the sector of education, some schools already implemented PTMT (Pembelajaran Tatap Muka Terbatas) by fully implementing face-to-face learning with some restrictions recommended by the government. One of the learnings that most teachers used was direct instruction. This study employed a sequential explanatory design to investigate the implementation of direct instruction in mathematics classrooms during the new normal. Firstly, we measured the effectiveness of direct instruction. Secondly, we investigated the factors affecting the results of our measurement of learning effectiveness. Two classes of the eleventh grade in one of the high schools in Makassar were chosen as the sample of our study. The findings of our study imply that the implementation of direct instruction in the mathematics classroom is not effective during the new normal based on the mathematics test results of the students. However, students and teachers respond positively to the implementation of direct instruction in mathematics lessons during the new normal. Our interview results reveal several factors causing the ineffectiveness, which were lesson duration, the number of tasks, and the short deadline of tasks from other subjects. Thus, the students cannot focus and overlook mathematics because they shift their focus to other subjects.
