Partway through my first semester in college, I tried drawing and labeling pictures as a study tool, and my grades on multiple choice exams improved. I decided to design an experiment to see if this same trick works more generally. I split up students into two groups in my LIFE 102 class: Group A were given the PowerPoint slides for lecture and asked to review the material for their weekly quiz based on the lecture notes only. Group B were given the same PowerPoint slides during lecture and asked to draw the content visible on the slides during lecture in their notebooks. I asked students to share their notes with me so I could confirm which students drew their own pictures and which students used lecture notes only. Then, I evaluated their quiz grades. Write an alternative hypothesis and a null hypothesis for my experiment. Then write a prediction for each of these hypotheses. Label them clearly, as in this structure: Alternative Hypothesis: [general statement of a phenomenon in present tense] Prediction: [specific outcomes of experiment if alternative hypothesis is true, future tense] Null Hypothesis: [general statement of a different phenomenon in present tense] Prediction: [specific outcomes of experiment if null hypothesis is true, must not be the same as prediction above, future tense]
