MAT 160 CC When and How to Let Learners Struggle Article Discussion
Learn by Doing
Here are the directions, grading rubric, and definition of high-quality feedback for the Learn by Doing discussion board exercises. As always, please do not continue without clicking on the Learn-by-Doing link in the previous sentence and reading every word!
Context
To prepare for this Learn by Doing discussion read the When and How to Let Learners Struggle (Links to an external site.) article (it's a blog post by Annie Murphy). This activity is included in the Reading Assignments and Quizzes portion of your grade.
Prompt
In your first post to the discussion respond to each of the following numbered items.
Watch Nike’s Michael Jordan Failure Commercial (30 sec) and then respond to the question.
In this video, what is the main point of Michael Jordan’s message? You should be able to state his main point in one short sentence!
Now watch Nike’s Michael Jordan Maybe It’s My Fault Commercial (1 min 2 sec) and then respond to the question.
In this video, what is the main point of Michael Jordan’s message, and how is it related to the main point in his Failure video? You should be able to state his main point in one short sentence as well!
What is the main point of the Annie Murphy’s blog post: When and How to Let Learner’s Struggle? You should be able to state her main point in one short sentence!
From the reading, what are the three conditions that promote beneficial struggle?
How are the messages in the article and the Michael Jordan videos related?
Do any of your instructors use the three conditions that promote beneficial struggle? If so, explain how and give examples. If not, use this space to write a quick note to a generic instructor explaining the value of productive failure and how to set up the three conditions that promote beneficial struggle in the classroom learning environment.
If you're comfortable sharing with your group, give an example in your own life where failure has been productive and actually contributed to your success (your instructor will read your response to this question as well). If you're not comfortable sharing a personal example, share how you plan to address setbacks in this class so that they contribute to your success.

Here are the directions and grading rubric for the Learn by Doing discussion board exercises.
A list of StatCrunch directions is provided at the bottom of this page.
Context
Clinical depression is a recurrent illness requiring treatment and often hospitalization. Nearly 50% of people who have an episode of major depression will have a recurrence within 2-3 years. Being able to prevent the recurrence of depression in people who are at risk for the disease would go a long way to alleviate the pain and suffering of patients.
During the 1980's the federal government, through the National Institutes of Health (NIH), sponsored a large clinical trial to evaluate two drugs for depression. There were 3 treatment groups. Patients received either Imipramine (Imip), Lithium (Li), or a Placebo (Pl). Researchers randomly assigned patients to one of the 3 treatment groups and followed them for 2-4 years to track any recurrences of depression.
(Prien et al., Archives of General Psychiatry, 1984).
Variables
Hospt: Which hospital the patient was from: Labeled 1, 2, 3, 5 or 6
Treat: 0=Lithium; 1=Imipramine; 2=Placebo
Outcome: 0=Success 1=Failure (recurrence of depression)
Time: Number of weeks until a recurrence (if outcome=1) or until study ended (if outcome=0)
AcuteT: How long the patient was depressed before the start of the current study, measured in days
Age: Age in years
Gender: 1=Female 2=Male
Data
If you have not done so already, download the depression datafile (as always, if a login box opens, just close it and then download the file). Then upload the file in StatCrunch.
Prompt
We will analyze the data to answer the 1st research question: Which of the drugs (if either) was more successful in preventing the recurrence of depression relative to the placebo?
In the previous lab-preparation activity, we determined that we will analyze the data using a two-way table and conditional percentages.
Use StatCrunch to produce a two-way contingency table. (directions)
Copy the table in your StatCrunch output window and paste it in your initial discussion post. (directions)
After you paste the content of the your StatCrunch output window into your discussion post, keep the table titled Contingency table results: and delete the Chi-Square results: table.
Analyze the data in your two-way table by finding appropriate conditional percentages. Write each conditional percentage as a ratio (e.g. 25 out of 40) and as a percentage (e.g. 25/40 = 62.5%). Then write a sentence that explains the meaning of the percentage in the context of the research question.
Draw a conclusion. Based on this study, which drug was the most effective in preventing the recurrence of depression? Support your conclusion using conditional percentages.
