EDUCATIONAL TIP FOR TEACHING:
The first technique is student self-assessment. Have the students give you a "thumbs up" if they're very confident in their understanding, a "thumbs sideways" if they feel so-so about it, and a "thumbs down" if they're completely lost. This gives you a quick, immediate sense of how your students are feeling.
The second method is to pose a simple question based on the material you covered. Have the students write three sentences, max, to answer the question. You can quickly read these over during a break or while the students work on another activity, and decide whether there's anything you need to clarify.
The third method is to have a volunteer share with the class a paraphrase of what you've said. Then, the students can discuss if anything was left out or different than what you taught. This allows students to learn from each other, and also gives you feedback on areas where students are still confused. (You can also break the students into small groups, where each group does this--it can help for shy students or large classes.)
There are many ways to check for understanding--these three are just some that have worked for me. Regardless of the method you use, make sure you are checking and not just assuming that because you've said it, students got it.
