Abstract

The purpose of this study was to determine the effect of discovery learning model on students' mathematical communication skills. All VIII grade students of SMP Negeri 6 Natar even semester of the 2023/2024 academic year as many as 209 students were used as the research population. The samples of this study were VIII E class consisting of 31 students and VIII C class consisting of 29 students selected by purposive sampling technique. The research design used was pre-test post-test control group design with class VIII E as the experimental class and VIII C as the control class. The data of this research is quantitative data obtained through student mathematical communication ability test. Hypothesis test analysis used in this study using t-test and proportion test. The results showed that the average gain data of mathematical communication ability of students who followed the discovery learning model was higher than the average gain data of mathematical communication ability of students who followed conventional learning and the proportion of students who had good categorized mathematical communication ability in the class that followed the discovery learning model was higher than the class that followed conventional learning. Thus, the discovery learning model is effective on students' mathematical communication skills.

Abstract

Teacher feedback plays an important role in supporting students’ learning motivation, particularly when it is integrated into the learning process through a well-structured didactic design. However, feedback in statistics learning is often still predominantly evaluative and has not been systematically used to guide students’ learning processes. This study aims to identify the types of teacher feedback provided to students in Class VII-A of SMP Negeri 26 Bandar Lampung and to describe students’ learning motivation after receiving feedback within a statistics didactic design. This research employed a qualitative case study design involving 31 seventh-grade students in the even semester of the 2023/2024 academic year. Data were collected through field notes, Likert-scale questionnaires on teacher feedback and student learning motivation, and interviews. The data were analyzed descriptively to identify patterns of teacher feedback and students’ motivational responses. The findings indicate that verbal feedback was the dominant form of feedback provided by the teacher. The most frequently observed feedback indicators were timely, specific, and process-focused feedback. In addition, students with high and moderate mathematical ability tended to show higher learning motivation than students with low mathematical ability. These findings suggest that process-oriented teacher feedback can support students’ motivation in learning statistics, especially when it is embedded in a structured didactic design.
