Abstract

In the past two years, scientific advancements have developed since the Coronavirus Disease of 2019. The Indonesian government has been forced to implement online learning activities led to several difficulties and hindered optimal learning experiences. This study aimed to analyze and describe the students’ low, moderate, and high mathematical communication skills on Number Patterns for Eighth graders of SMP Negeri 48 Surabaya, Academic Year 2022-2023. This study used descriptive qualitative research design. The data were collected using testing, interviews, and documentation. The results showed that students with high mathematical communication skills were able to demonstrate all indicators effectively. Students with moderate mathematical communication skills have achieved indicators related to expressing their understanding through mathematical concepts and graphical representations, but struggled to meet the indicator for creating mathematical models based on given problems. Students with low mathematical communication skills were able achieve indicators related to expressing their understanding through mathematical concepts, but failed to meet the indicators for expressing their understanding through graphical representations and creating mathematical models based on given problems. Based on the research findings, the authors suggest using an interactive learning model to improve students' mathematical communication skills, both written and oral. This model should actively involve students and address any knowledge gaps resulting from online learning.

Abstract

Based on the preliminary study conducted by the researchers in the field, there has been a decrease in students' learning outcomes at SMA Kartika Surabaya due to the prolonged implementation of online learning. Therefore, this research aims to enhance understanding by investigating the influence of the Project Based Learning Model on students' learning outcomes in statistics. The research employs a quantitative statistical analysis. The sampling where twelfth class of natural science 1 as the experimental group and twelfth class of natural science 2 as the control group. The data were collected using test based on students' learning outcomes and analysed for normality, homogeneity, and hypothesis testing. The results showed that the average learning outcomes of students taught using the Project-Based Learning Model are higher than those taught using the conventional model. The results of the hypothesis test using the independent sample t-test with a significance value (sig.) of 0.004 < α = 0.05, indicating H0 was rejected and H1 was accepted. Based on the research findings, it can be concluded that there is an influence of the project-based learning model on students' learning outcomes in statistics for twelfth class of natural science at SMA Kartika IV-3 Surabaya.
