Analysis of teacher’s ability in planning and implementing learning on vibration, wave and sound submaterials

Submaterial vibration, waves and sound in junior high school science learning has high complexity. Teachers must not only master the material, but also they must be able to plan and implement the learning process. This study aims to analyze the ability of teachers to plan and implement learning on vibration, wave and sound material. This research is descriptive with a qualitative approach. The data collection techniques involved assessment of the lesson plans and observation of learning implementation to obtain the primary data. The secondary data are sourced from lesson plans, teacher and student interviews. Data were qualitative analyzed. Based on the analysis of the learning process shows that (1) the ability of teachers to make lesson plans in terms of format in accordance with aspects of the assessment of IPKG-1 with a score of 79.97% in the category is quite good. Lesser lesson planning indicators include learning objectives, methods, and procedures. learning plan (RPP) is not in accordance with the syllabus (2) the ability of teachers to apply is in accordance with aspects of the assessment of IPKG-2 with a score of learning implementation of 79.5% in the good enough category. Indicators of poor learning implementation are directing students to 21st century skills and lack of application of basic competencies.
