Rubrics
I like
rubrics because in my long career as a student I often did not know what the
teacher expected. I would ask and get vague answers.
Rubrics
should tell students what is expected. Students want to know how long an answer
is required. Have you ever asked that question and received an answer like: “As
long as necessary” but then, when the answer is submitted had points taken off because
it was too long or too short? I have.
Students should also know what is how they will be graded. I have found that including examples of good and poor submissions
from past classes really helps students.
Common rubric mistakes:
- Adopting a rubric from an online site that does not fit the assignment.
- Too detailed.
- Being so inclusive that it makes the assignment time consuming for the teacher to grade.
- Going from low to high instead of high to low in the scale.
I do
not think rubrics are the complete solution. For several years I was a reader
of grants. There were usually 4-5 people on a team, and we had a rubric, and we
scored individually first sand then came together and compared our
answers. Although we all had the same
rubric our scores often were very dissimilar. So, rubrics yes, but also written
feedback to students. I think every rubric should include a column for teacher
feedback, explaining why the grade was given. More work for the teacher? Yes.
More fair to the students? Definitely.

Adding Pictures to Your Online Class
IMPORTANT note on pictures of people: You should also be
careful of including pictures of people in your online course. HIPPA and FERPA
guidelines should be followed.
You should have their written consent to do this. I know it
is done all the time, but it only takes one time for somebody to get upset and
then you are in trouble. Also some students copy pictures from our classes and
post them on sites like FaceBook, and that can be a problem.
I would suggest that you start with graphics from a public
domain site. One site is http://antiqueclipart.com/
or http://office.microsoft.com/en-us/clipart/default.aspx
NOTE ON COPYRIGHT:
The CONFU (conference on Fair Use) has established the

author.
·
Up to 10% or 15 works,
whichever is less, from a collection

Criteria for Adding Multimedia in the Online Classroom
Adding multimedia to the online classroom can enhance
student learning. It can also distract from content and be a time waster. In making decisions as to what multimedia to
add I use the following criteria:
- 1. Does it add a missing piece to the content?
- 2. Is it easy for the students to access?
- 3. Is it relatively easy for me to create, or to find on the Web?
- 4. If it is on the web is the source reputable?
- 5. Is there a text alternative, which is required by ADA?
#1. As a teacher of teachers I see a lot of multimedia being
added to class because it is “glitzy.” A certain amount of “glitz” does make
the class interesting. It is, however, easy to go overboard. One teacher put an
emoticon in every message posted. After a while it was too much and a
distraction.
#2. I realize that sometimes students have slow connections,
and multimedia takes a long time to load. Recently I was away from my home
computer and, although I could get WiFi, the connection was dial-up. When I
tried to access a video I could get to it, but received the message that a 6-minute
video would take an hour to download. This is not acceptable for students.
There must be an alternative.
#3. While I believe every teacher should have the support of
an IT department usually the Instructional Technologists are overloaded.
Teachers must be trained to do a lot of the work themselves, and often some
will enjoy developing multimedia content. However, there is much already on the
web, and teachers just need to know where to find it. I have a Diigo.com
account that is a web site exchange where teachers share web sites. I find it
very useful.
#4. However, not everything on the Web is worthwhile. Just
as we tell our students to only use academic sources we should always check the
author of any web-based multimedia creations (videos, games, graphics) that we
share with the class. And, as teachers, we should be aware of Copyright law. We
cannot just download and use without permission. We can link to web sites, but
downloading to our computer is often not compliant with copyright.
#5. Not all students can profit from multimedia. A text alternative
is required for ADA. This also helps
students with slow connections, or computers without sound cards (yes, there
are some of those still around).
