Focus Group Comments on the Traditional Large Lecture Experience at ND • “I don’t keep up with the reading for lecture, because we don’t have any discussions in lecture. I’m better off spending the time reading for other classes where we do discuss things.” • “I am afraid to ask questions in such a large lecture hall.” • “I don’t feel responsible for what happens in class.” • “The large lecture lets me remain anonymous, which is good.” SUN Conference - UTEP

The Primary Learning Goals for General Chemistry at Notre Dame • Learn through inquiry and exploration. • Work collaboratively with classmates to visualize, understand, and describe chemistry at the molecular, macroscopic, and symbolic levels. • Utilize critical thought and intuition to predict chemical behavior (structure and reactivity). • Develop original solutions to problems that you have not encountered before.

The Levi Straus trademark shows two horses trying to pull apart a pair of pants. Suppose Levi had only one horse and attached the other side of the pants to a fencepost. Using only one horse would: (a) cut the tension on the pants by one-half. (b) not change the tension on the pants at all. (c) double the tension on the pants. SUN Conference - UTEP

What are the benefits of asking concept questions in class? • Students will • Articulate preconceptions and defend ideas • Hear multiple perspectives • Practice speaking the language of the discipline • Become more invested in the topic • Receive an accurate form of self-assessment • Instructor will • Gain immediate feedback on student understanding and readiness for new material.

When we use the remote keypads, I receive valuable feedback on how well I understand the course material. Survey Data gathered by www.textrev.com SUN Conference - UTEP
I appreciate the way that the remote keypad technology allows me see what my classmates are thinking. Survey Data gathered by www.textrev.com SUN Conference - UTEP
I pay greater attention in class when I know the instructor will ask me to periodically answer questions on my remote keypad. Survey Data gathered by www.textrev.com SUN Conference - UTEP
Do you recommend that the instructor use the remote keypads in this course in the future? Survey Data gathered by www.textrev.com SUN Conference - UTEP
Questions I Ponder about my Students • How accurately do my students assess their own level of understanding or misunderstanding? • When students with differing opinions debate a question, does their discourse increase their understanding? Does it leave them more or less confident in their own understanding? • To what extent does a student’s metacognition guide and regulate her study? SUN Conference - UTEP

Summary • Students learn best when they are engaged in applying their new skills and conceptual understanding to matters of consequence. • Remote keypads offer students the potential to • Fully participate in class discussions, even within a large lecture setting. • Receive instantaneous feedback and self-assessment. • Be encouraged for progressing in both accuracy and confidence. • Community-based learning adds value to • Students’ professional, academic, and personal development. • The lives of families facing environmental hazards.
