The video is about developing critical thinking skills in the language classroom. The speaker begins by defining critical thinking and its importance. They then discuss Bloom’s Taxonomy, a model for classifying educational learning objectives into levels of complexity and specificity. The speaker argues that lower-order thinking skills, such as remembering and understanding, are more teacher-centered, while higher-order thinking skills, such as analyzing, evaluating, and creating, are more student-centered. The speaker then breaks down critical thinking into subskills, including analytical skills, research and reasoned judgment, problem-solving skills, decision-making skills, reflective thinking, and communication skills. They provide examples of how to develop each of these subskills in the language classroom. The speaker concludes by emphasizing the importance of asking questions, facilitating learning, and valuing diverse voices in the classroom.
