A teacher wants his students to learn how to solve a variety of statistics problems. He teaches
them using worked examples, and encourages them to memorize formulas and algorithms using
flashcards. On weekly homework assignments, the students can effectively apply techniques
learned that week to assigned problems. However, on the final exam, he finds that many students
mix up the techniques and use approaches that are inappropriate for the task. They do not
struggle to remember the techniques, but they use them at the wrong times. Suggest a change the
teacher can make to address this problem, and explain why that change will help.
