Biology Module Development Using Think Pair Share Strategy to Improve Critical Thinking Skill of Vocational High School Students

The purpose of this research and development is to create a product in a form of Biology learning module using think pair share strategy as an effort to improve critical thinking skills of vocational high school students. The research and development method used for this research was Borg& Gall (1985) development model. The development module has fulfilled validity criteria and adequate as a Biology learning material using strategy think pair share to improve critical thinking skills of vocational high school students. Critical thinking data was collected using critical thinking skill test suitable for validity and highly reliable as an instrument. Research shows that Biology module equipped with think pair share has improved the critical thinking skill of vocational high school students with normalized gain score on early field test at 0.77 (categorized as high), main field test at 0.8 (categorized as high), dan operational field test at 0.82 (categorized as high), hence it was recommended to use this Biology module in learning process to improve the critical thinking skill of vocational high school students.
