Anticipated Graduation Date:
Section I: Time Management Plan
Time Management Plan: Sample Weekly Timetable
Use the table below to input the following:
· Common, non-school-related commitments. These may include
sleep—yes, scheduling your sleep is important—work
schedules, meals and meal preparation, community activities,
social commitments, and so on.
· Dedicated time for study and assignments in your courses.
Keep in mind that you should plan on 14–15 hours per week for
each course in which you are enrolled. Try to be specific about
how you will use your school time (e.g., “prepare discussion
post,” “complete module reading,” “plan for weekly
assignments,” “check in with instructor”). You may wish to use
the assignments for the next module in this example.
You can split up the hours below into smaller increments by
clicking in the table and adding a row above or below any of the
cells.Sample Time Schedule

Time Management Plan: Identify Black Holes
After completing the sample weekly schedule above, take a
moment to reflect on the possible “black holes” that may impact
your time schedule (e.g., unplanned appointments,
procrastination, Facebook or other social networking sites,
interruptions with children). As your textbook noted, ". . . most
people find that they're spending time on a lot of activities that
just don't matter very much" (Feldman, 2014, p. 36). In the
section below, identify one or two black holes and provide a
brief description (one to two paragraphs, using complete
sentences) on how the black hole may impact your schedule and
how you will reduce disruptions.
Black Holes Reflection:
Section II: Academic Mission Statement and GoalsRevision of
Mission Statement and Academic Goals
Below, include a revision of your academic mission statement
and short-term goals from Final Project I, which you submitted
in Module Five. Use your “how to use rubric feedback for
growth” skills, and make sure you are considering the feedback
you received from your instructor. Also be sure to clean up any
written errors in the submission. If you wish to refocus your
mission statement, you are encouraged to do so here.
Type your revised mission statement and academic goals in the
space below:
Section III: Social, Motivational, and Academic Support
StrategiesStrategy or Amenity Alignment and Importance
As you consider your mission statement, academic goals, and
time management plan, identify three specific strategies or
amenities (resources) you are going to utilize to help
accomplish your goals. Consult the “Additional Resources” and
“Academic Support” menu links in your course for assistance
identifying appropriate strategies or amenities.
For each strategy or resource, explore the following:
· Identify the strategy or amenity and how it aligns with your
mission statement, academic goals, time management plan, or
SmarterMeasure results.
· Why is this strategy or amenity important for your academic
success in an online environment? How will this help you
address your specific social, motivational, and/or academic
needs?
Name of Strategy or Amenity One:
How it aligns with your mission statement, academic goals, time
management plan, or SmarterMeasure results:
Why it is important to your academic success in an online
environment:
Name of Strategy or Amenity Two:
How it aligns with your mission statement, academic goals, time
management plan, or SmarterMeasure results:
Why it is important to your academic success in an online
environment:
Name of Strategy or Amenity Three:
How it aligns with your mission statement, academic goals, time
management plan, or SmarterMeasure results:
Why it is important to your academic success in an online
environment:
Section IV: Ownership of Online SuccessOwnership of Online
Success: Ownership and Measurement
Using the same strategies and amenities you identified above in
section III, answer the following:
A. You have identified three specific strategies or amenities
that will help you on your path to success. Now, think about
your personal ownership of theuse of the strategy or amenity
and its importance to your academic, social, and/or motivational
success or needs in an online environment. Why is it important
for you to take charge of these resources, and how will their
implementation help you achieve future online academic
success? (Consider this: Why might it be even more important
in an online environment to take personal ownership of these
strategies or amenities than it might be in a traditional
classroom?)
B. Now that you have identified your strategies and amenities
and connected their use to your personal goals and needs, how
will you measure your own success in planning to use these
strategies or amenities? For instance, if you commit to using the
SNHU Writing Center, a measurement of success might be
successfully setting up a writing appointment at the beginning
of your next term (or every term) to discuss support. How will
you identify if you are using the strategies and amenities
successfully?
Name of Strategy or Amenity One:
A. How will your ownership of this strategy or amenity support
your success in an online environment? Explain:
B. How will you measure your own success in using this
strategy? Explain:
Name of Strategy or Amenity Two:
A. How will your ownership of this strategy or amenity support
your success in an online environment? Explain:
B. How will you measure your own success in using this
strategy? Explain:
Name of Strategy or Amenity Three:
A. How will your ownership of this strategy or amenity support
your success in an online environment? Explain:
B. How will you measure your own success in using this
strategy? Explain:

If you wish to use a modified template, have your instructor approve an early draft. Name: Student ID: Program(s) of Study (Major): Anticipated Graduation Date: Section I: Time Management Plan Time Management Plan: Sample Weekly Timetable Use the table below to input the following: · Common, non-school-related commitments. These may include sleep—yes, scheduling your sleep is important—work schedules, meals and meal preparation, community activities, social commitments, and so on. · Dedicated time for study and assignments in your courses. Keep in mind that you should plan on 14–15 hours per week for each course in which you are enrolled. Try to be specific about how you will use your school time (e.g., “prepare discussion post,” “complete module reading,” “plan for weekly assignments,” “check in with instructor”). You may wish to use the assignments for the next module in this example. You can split up the hours below into smaller increments by clicking in the table and adding a row above or below any of the cells.Sample Time Schedule TIME BLOCK MONDAY

Use your “how to use rubric feedback for growth” skills, and make sure you are considering the feedback you received from your instructor. Also be sure to clean up any written errors in the submission. If you wish to refocus your mission statement, you are encouraged to do so here. Type your revised mission statement and academic goals in the space below: Section III: Social, Motivational, and Academic Support StrategiesStrategy or Amenity Alignment and Importance As you consider your mission statement, academic goals, and time management plan, identify three specific strategies or amenities (resources) you are going to utilize to help accomplish your goals. Consult the “Additional Resources” and “Academic Support” menu links in your course for assistance identifying appropriate strategies or amenities. For each strategy or resource, explore the following: · Identify the strategy or amenity and how it aligns with your mission statement, academic goals, time management plan, or SmarterMeasure results. · Why is this strategy or amenity important for your academic success in an online environment? How will this help you address your specific social, motivational, and/or academic needs?

You have identified three specific strategies or amenities that will help you on your path to success. Now, think about your personal ownership of theuse of the strategy or amenity and its importance to your academic, social, and/or motivational success or needs in an online environment. Why is it important for you to take charge of these resources, and how will their implementation help you achieve future online academic success? (Consider this: Why might it be even more important in an online environment to take personal ownership of these strategies or amenities than it might be in a traditional classroom?) B. Now that you have identified your strategies and amenities and connected their use to your personal goals and needs, how will you measure your own success in planning to use these strategies or amenities? For instance, if you commit to using the
