Content analysis of critical-rand creative-thinking skills in middle-school science books on environmental pollution material

Critical- and creative-thinking skills are important competencies students must have to encounter the challenges of the 21 st century. The development of teaching materials that emphasize critical- and creative-thinking skills is very necessary for students to improve these skills. This research aims to analyze three middle school science books based on critical- and creative-thinking skills on environmental pollution material.

The development of critical-thinking skill indicators refers to Facione while the indicators-of creatives thinking skills refer to Torrance. The results of the analyses show-that the average critical-thinking skill indicator achievement for the environmental pollution material on interpretation is 2.83%, analysis 2.75%, conclusion 3.16%, evaluation 2.83%, explanation 2.91%, and self-regulation 2.33%. The achievement of creative-thinking skill indicators on average is 2.66% for fluency, 2.66% for flexibility, 2.41% for originality, and 2.75% for elaboration.
