Abstract

Classroom learning requires effective communication between teachers and students to create a conducive environment and enhance learning. This study analyzes the impact of teacher communication on students' interest in learning exponents using a descriptive approach. Data were collected through observation, interviews, and documentation involving 10th-grade students and a mathematics teacher at a vocational school in Yogyakarta, selected via purposive sampling. The findings show that effective communication increases students' motivation, active participation, and understanding of exponents. Interactive methods, such as discussions and QA sessions, foster student engagement and improve their grasp of the material. These results highlight the critical role of teacher-student communication in creating an enjoyable and effective learning experience, ultimately supporting better academic outcomes.

Abstract

This study aims to examine the effect of altitude on the acceleration of gravity with the help of smartphone acoustic sensors. The altitude varies from the interval 100-1061 MASL (Mean Above Sea Level), located around the Special Region of Yogyakarta. An iron ball is dropped from a certain height, and the time it falls is observed using an acoustic sensor in Phypox, and the results are used to determine the acceleration value due to gravity (g) through the equation g = 2h/t2. Fitting data from measurements of the four altitude variations are shown in the polynomial equation y = 0.000003x2 – 0.0035x +10.718 m/s2 with a regression number R2 = 1,000. This equation shows that the acceleration value due to gravity will decrease quadratically with each increase in the altitude per meter above sea level.
