Active Learning Activity 1.4 - Distinguishing Between Experimental and Correlational Studies Purpose: To allow students to practice using the concepts they have learned. To develop the critical thinking skill of applying new concepts to real-world situations, using cases drawn from newspaper reports. To help students become better "consumers of information;" to remind them that methodology is rarely reported in the media. Instructions: 1. Following your presentation of correlational and experimental studies, distribute Handout 1.4 – Active Learning. 2. Students can do this exercise in groups or individually; groups of 3 or 4 are the most effective. 3. Instruct students to do the worksheet first individually and then to check with the other students. If there is disagreement, they can refer to the text or to you. Review the correct answers.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
