Question Answered step-by-step Lecture Activity 10.02 Teaching Styles Dr. Phillips is studying how… Lecture Activity 10.02 Teaching Styles Dr. Phillips is studying how children learn multiplication. He wants to know if different teaching styles lead to better learning. He recruits 54 second-graders who have not yet learned to multiply. Students are randomly assigned to one of three groups: Group A reads about multiplication in their textbook; Group B watches a cartoon video that explains multiplication; Group C is taught multiplication by a teacher. All groups spend 30 minutes learning multiplication and then take the same 15-question multiplication test. Here are the results.

Draw a diagram showing the study design. 2. Based on the results of his study, Dr. Phillips hopes to make a causal statement. Explain how his study does or does not meet the three rules of causation. Rule 1: Rule 2: Rule 3: 3. Identify the independent variable(s), dependent variable(s), and a control variable in Dr. Phillips’ study.
