There are many posts regarding this topic. I didn't realize there were so many until I conducted a research Google search. 324,000,000 results to my query. Wow, I'd spend a lot of time if I had to review all of those!
Suggestions from "8 Ways to Help Students Manage Their Time" by Lisa E. Stafford (American Forces Press Service WASHINGTON, June 30, 1998) include the use of a student planner, creation of a homework schedule and the advice to stick to the schedule and use incentives, not threats.
Another suggestion would be the use of a timer, whether at home or in a classroom. Here's a link to a virtual timer.
In, Manage Your Work, Don't Let it Manage You: Tips for Managing Your Time and Getting Ahead, offers tips not just for students but for educators as well. This list would be most valuable for discussion in a Personal Learning Community, especially tip number 4, 'Avoid Overload'.
Perhaps you will find this time management slideshow useful as a class discussion starter.
There are several items in Thinkfinity that present information on time management.
I hope you find the time this school year to reach all of your goals. But remember that you need to "Take Time" as well.
