*Transformative Teachnological Teaching Tools*

In The Evolution of the Lecture I posed the question, “could we live without lectures?” and while far from the first to do so, I suggested that lectures need to evolve in our modern world. Clearly technology can enhance education, but how should it be incorporated? And, what tools are out there? Technological teaching tools and materials are advancing so quickly that it’s impossible to give a comprehensive list or try to use all of them in a course, but I will present a few that have proven very useful to me and many seasoned educators.

Make your presentation slides come alive! Powerpoint slides are usually quite dull; these days, don’t you want interactive math, animations, graphs, and visualizations in lectures? Mathematica makes this incredibly easy. Mathematica is like a super-graphing-calculator for your computer, but it can also be used for presentations. For example, if you’re writing a lecture, instead of introducing a function such as Sin(x)Sin(y), you can use one simple command, “Plot3D,” to make it appear as an ocean of waves (below). Then you can use another command, “Animate,” to make that ocean move and flow! Next time you are presenting something involving math, statistics, or plots, before choosing a static presentation, try using Mathematica. Then when someone asks you a question you can even do the math and visualizations inside the lecture slide.

Never lecture on basics again! Kahn Academy provides over 4,000 online lectures on many academic topics. If you want to learn about algebra, the economic crisis, or hear Lebron James ask about Newton’s 3rd law (and get the answer), you can do so on Kahn Academy. So before writing a lecture on, say systems of equations, first check www.khanacademy.org to see if there is a video that you can direct your students to so you can spend class time more interactively (answering questions, playing games, group work, etc.)

Never answer the same question twice! Piazza is a new tool that helps take your students’ questions and your answers (as well as answers from their peers) online. Students can use this online tool to ask their question to the entire class (students and teachers) with the option of anonymity, and anyone can reply. This way students and teachers can learn from answers to inquiries anyone in the course has posed. So, the next time you find yourself answering the same question twice, or want help answering questions from students in the class, check out Piazza.com.

Many tools are now being developed, and since each class could be enhanced by different technologies, teachers should think carefully about which are best suited for their courses. If they do, I am optimistic that the extinction of boring lectures is nigh.
