Integrating Student Tablets Into Lectures

Over the spring semester and a week in the summer I completed a professional development course at Fresno State for an initiative known as DISCOVERe.  The purpose of the DISCOVERe program is to support faculty in redesigning their courses to leverage the benefits of tablets, so that students can improve their conceptual knowledge while also developing their technology skill-set.  I will be teaching my tablet-supported General Chemistry class starting next week with over 100 students.  I hope to share some of the things I learn over the course of the semester through blog posts and to gain insight from others.

Before taking the DISCOVERe course I was a little skeptical about students using tablets within a lecture-based approach.  From my research, I know many ways that educational technology benefits students' learning.  However, using tablets in lectures presented me with a mismatch of what is typically a teacher-centered approach and the student-centered approach that using tablets would require.  I realized that DISCOVERe was asking me much more than to simply use tablets.  DISCOVERe was asking me to question my role and my students' role within my classes in order to effectively leverage the benefit of tablets.

In terms of Chemistry Education, there are great and open-source simulations that help explain many microscopic concepts such as the atom, concentration or pH.  Such concepts are difficult for students to grasp given that such phenomena cannot be seen with the naked eye.  Some examples of helpful simulations to support students include PhET simulations, Molecular Workbench, and Chemcollective. Before the DISCOVERe program, I was using these resources in a mostly didactic manner through demonstrations, despite a Predict-Observe-Explain (POE) approach.  Students would make predictions about a phenomenon through iClickers, I would demo the simulation, and then I would call on individual students to offer explanations. 

The prediction part of my POE approach was fine, but the advantage of using tablets this semester is that my students can now simply follow a link to observe and explore the simulations, as opposed to being bored by observing me do a demonstration.  My role can now switch from demonstrating to ensuring all students are able to use the simulation on their own.  Further, through the DISCOVERe program, I had the opportunity to trial Socrative, which allows for students to submit open-ended responses.  I previously had obvious difficulty in getting a response from all students in a large lecture class given time constraints, but through Socrative all students have an opportunity to participate and share their ideas on the simulations.  I will be able to view student responses in real time to get a much broader sense of their understanding than before and know what conceptual challenges to target.

I am looking forward to thinking about other ways to take advantage of tablets in my course throughout the semester.  I can already see from the activities I am developing that there will be better opportunities for student engagement.  I think what might be challenging is if students are ready to see their role as taking more ownership.  Much of this responsibility can reside with individual students, but I can help this process by setting clear expectations of students' role at the beginning of the semester and by consistently using activities that align with such expectations.
