L esson: Redox Reactions Topic: Bloom's Taxonomy As we know, Bloom classified levels of thinking into six: 1- Remember 2- Understand 3- Apply 4- Analyze 5- Evaluate 6- Create After observing the explanation of this Chemistry teacher, it was clear that the teacher has followed “Bloom’s Taxonomy” in presenting the lesson for the class. This stands for the levels of thinking of both “teacher and students”. When the teacher started with a new type of reactions which was “redox”, he was aware to recall the definition of a reaction. What is a reaction? So by this way the teacher depend on the first level of thinking “knowledge” . In addition, when the teacher explained the method of calculation for the oxidation number of Cr in Cr 2 O 7 2- . The teacher asked a student to rephrase the method (how we get the oxidation number of Cr) in his own words. By this strategy, the teacher was following the second level of thinking “comprehension” . When the ideas
