This is from the 2012 Texas GOP party platform: We oppose the teaching of Higher Order Thinking Skills (HOTS) (values clarification), critical thinking skills and similar programs that are simply a relabeling of Outcome-Based Education (OBE) (mastery learning) which focus on behavior modification and have the purpose of challenging the student’s fixed beliefs and undermining parental authority.
The official spin is that this was a mistake - they didn't mean to oppose the teaching of critical thinking skills - just higher order thinking, apparently. Texas GOP rejects ‘critical thinking’ skills. Really. - The Answer Sheet - The Washington Post |
