Abstract

The 2013 curriculum is intended to develop students’ 4C skills. The basic competence of respiratory system material will be appropriately implemented by PjBL and STEM. The research purpose is describing the validity and practicality of learning tools. This research belongs to research and development particularly to the measurement of validity and practicality. Data Analysis used descriptive quantitative and percentage. The findings: (1) learning tools were very valid include syllabus with score 88.54; the lesson plan with score 86.91; learning material with score 85.54; students’ worksheet with score 85.83; the evaluative instrument with score 86; construct validity of Critical Thinking test obtained rcalculated 0.54 > rtable 0.304, reliability test was 0.70 – meaning the test was valid and reliable. (2) Learning instrument was practicable. This research adds scientific insight especially about learning tools that are able to train students’ 4C skills. In conclusion, the STEM PjBL learning tools was valid and practicable.
