There can be a few very vocal students who strongly oppose clickers, but our surveys have shown that when clickers are used well, this view is never shared by more than a small minority. If they are troublesome, their complaints can be reduced by surveying the class to show that they are a small minority, rather than representing the sentiment of all (as they usually assume). Also, although most students say they like using clickers, even those who do not often still recognize their value. In the words of one such student we interviewed,

Using clickers is like broccoli – I don’t like it, but it’s good for me.

Finally, the most effective way to eliminate student resistance ultimately is simply to use clickers to make the classroom an extremely stimulating place where students are highly engaged and learning a great deal.

10. won’t i lose control of the class if i let them talk so freely?

This is not as big a concern in practice as it is usually feared to be. There certainly is less rigid control of the class, but students also see the class as more supportive of their learning, and so they are more on your side from the beginning. It is helpful to lay out some ground rules clearly. Along with the reasons for having clicker questions and discussion, make it clear that discussion is supposed to be limited to the subject material (even though it will not always be), and that when you have signalled it is time for discussion to stop, they should do so, and any questions remaining at that time should be directed at you. As the term progresses and students get to know each other better and become more comfortable talking to each other, it usually does get more difficult to cut off discussion. Training students from the beginning to respond to some signal like a gong or lights flashing markedly reduces the difficulties and is normally adequate.

If just a few students continue to talk, ask them directly in front of the class in a non-confrontational way, if they have a question. If they are discussing non-class related material, that will quiet them then and in the future. If they are discussing the class material, which is more typical, they will ask a question which you can treat like a regular question, and still send the message clearly that they were disruptive. It is unlikely, but not impossible that you may have an exceptionally unruly class where even these steps are not sufficient to quiet them down. (It is not clear whether such classes are made worse or better with clickers.) A reasonable approach we have seen for that case is, if class is not quiet after the gong/signal, simply stand there looking at them and wait. If they continue to talk, make it clear that students will be responsible for material not covered because of the time you spent waiting for class to quiet down, and then when there are subsequent disruptions, just continue to wait them out and rely on student peer pressure to deal with the noisy students.

11. how do i respond if technical problems arise during class?

Reassure students that technical problems in no way impact any grading scheme you have implemented. Then pose the question anyway and have discussions as originally planned, and ask for the show-of-hands approach to answering. Results can be tallied (even if roughly) on paper, the blackboard, or an overhead projector.

12. should i post answers to clicker questions after class or not?

There are varying opinions about this and no data that indicates one way or another. However the work in reference 2 shows that when people have the answer explained to them after they have thought hard about how to answer the question, they learn a large amount from the explanation. On the basis of that research, our inclination is that it is probably better to post the answers.

13. do clickers work in upper level courses or are they only good for introductory?

We have several examples of instructors who began using clickers in large introductory courses and then tried them in smaller upper level and even graduate courses. They are very enthusiastic about the results, and students in upper level clicker courses strongly supported this use on our surveys.

In summary, we have found the effective use of clicker questions and discussion can have a transformative impact on both teachers and students, particularly in large classes. Students end up being far more actively engaged in the material and they learn more, and both students and instructors find the course much more rewarding as a result. If you are currently using clickers, we hope this guide will give you ideas on how to use them more effectively, and if you have not yet tried them, we hope this will provide you with the encouragement and assistance to use them effectively.

Questions & Answers

can someone help me with some logarithmic and exponential equations.
Jeffrey Reply
sure. what is your question?
ninjadapaul
20/(×-6^2)
Salomon
okay, so you have 6 raised to the power of 2. what is that part of your answer
ninjadapaul
I don't understand what the A with approx sign and the boxed x mean
ninjadapaul
it think it's written 20/(X-6)^2 so it's 20 divided by X-6 squared
Salomon
I'm not sure why it wrote it the other way
Salomon
I got X =-6
Salomon
ok. so take the square root of both sides, now you have plus or minus the square root of 20= x-6
ninjadapaul
oops. ignore that.
ninjadapaul
so you not have an equal sign anywhere in the original equation?

The answer is neither. The function, 2 = 0 cannot exist. Hence, the function is undefined.

Prasenjit Reply
At high concentrations (>0.01 M), the relation between absorptivity coefficient and absorbance is no longer linear. This is due to the electrostatic interactions between the quantum dots in close proximity. If the concentration of the solution is high, another effect that is seen is the scattering of light from the large number of quantum dots. This assumption only works at low concentrations of the analyte. Presence of stray light.
