Throughout the ages of educational ideas and philosophies teachers have been big fans of having their students keep a journal. Journals are kept in language arts, foreign language classes, and I have seen them in science classes. Students don't particularly like doing them unless they enjoy writing. If given a choice between keeping a journal in their spiral notebook and keeping it online, I would wager that a majority of students in this digital age will prefer to keep it online. So why not give them the choice and tool of Penzu.
I have never been a fan of lecturing during class...for either the high school or college classes I teach. If there is information I need to share, I will always use a Power Point (or something similar) and then make those files available for students to download. But even when presenting information in this manner, I continue to engage students with questions, asking for real life examples, etc. And I limit the time, or break it up with another activity. It seems to work pretty well and the ideas from this article pretty much confirm what I have always felt about the lecture style class.
