Title: Saving our Coral Reefs

Saving our Coral Reefs
  • Presentation created by Janette Hill
  • based on IDAs completed by
  • Marty Thomas

Whats Going on with our Coral Reefs?
  • The U.S. Coral Reef Task Force estimates the
    coral reefs provide 375 billion annually in
    natural resources although they only cover less
    than 1 of the earth's surface. Although coral
    reefs offer many benefits to society, there are
    some negative trends taking place that scientists
    believe are indications that the coral reefs may
    be extinct within 50 years. Some of the problem
    seems to be a lack of awareness (I was unaware of
    the situation until I began to study marine

Whats the Problem?
  • Society, by and large, is unaware of the
    deterioration of the coral reefs and the impact
    these events will have on our environment. More
    importantly, we as a society are very
    uncomfortable with how we can prevent the coral
    reefs from becoming extinct. Learners are not
    adequately prepared to help repair the coral

Where will the instruction be implemented?
  • This instruction will take place in lab
  • Important equipment in the labs include at least
    one 200-300 aquarium.
  • Lighting requirements at each aquarium are
    approximately 700 watts.
  • The lab will require several computers since the
    instruction will either be delivered on DVD or
    via the Web.

Who are the learners?
  • Young adults - adults (1575 years old).
  • Learners will have a basic knowledge of coral
    reefs (i.e., the Great Barrier Reef is in
    Australia) and an interest in marine biology.
  • Some preliminary assessment is needed to
    determine that the learners are capable of
    understanding biological terms at least at the
    high school level.
  • Also important that learners are comfortable
    working in a team setting.

What is the goal of the lesson?
  • Larger course context maintain coral reef
  • Unit visually determine causes of coral reef
  • And finally the lesson (coming up!)

Heres the Overall Course Picture
Course Objective Maintain coral reef systems
Unit 1 Visually determine causes of coral reef
Unit 2 Use reproduction knowledge for coral
Unit 3 Benefits of coral reefs
Unit 4 Reproduction processes of coral
Lesson Structure
Lesson Obj Learners will list the sources of
coral reef damage (declarative knowledge)
Obj 2 Predator damage
Obj 5 Relationship between humans environment
Obj 1 Warming water impact on coral reefs
Obj 4 Impact of environment on coral reefs
Obj 3 Impact of humans on coral reefs
How will the learning be assessed?
  • Learners will identify the sources of coral reef
    damage (warming waters, types of human damage,
    predator damage).
  • Five multiple choice questions
  • Mastery is 4 out of 5 correct

The Lesson!
  • Attention will be garnered with the use of two
    aquariums one healthy, one unhealthy.
  • Purpose The two aquariums are representative of
    a pattern of what is happening with our coral
    reefs -- our task is to explore why.
  • Interest and motivation will be enhanced with

The Lesson (continued)
  • Learners will practice throughout the
    instruction As the learner answers periodic
    questions throughout the video instruction, the
    system will initially provide hints to incorrect
    answers (i.e., recall earlier clips that showed
    the following). After several missed attempts,
    the system will provide feedback for material the
    learner can review for remediation.
  • See IDA 5 for all the detail!

The Media Used for Instruction
  • DVD (institutions can order the DVDs online).
    DVD will include video and executable programs
    the institution will need install on local
    machines. The executable programs will install
    the simulations and microworlds.
  • Hands-on practice with real aquariums in the lab.

Evaluation Time!
  • Experts will review the instructional list of
    sources for coral reef damage for
  • 1) Completeness
  • 2) Accuracy
  • Experts will help to ensure the instruction
    includes all the possible sources of coral reef
    damage. Completeness review by the experts
    should also discuss areas that are not covered
    with sufficient depth in the instruction. The
    experts will also help to check the instruction
    for errors in the information.

And More Evaluation!
  • Small group of learners
  • Randomly sample 2 learners from the novice,
    average and experienced groups to again evaluate
    the learnability of the instruction.

Lessons Learned
  • To be added Saturday afternoon on the fly and
    the formal report written at a later date for
    submission by Wednesday, 4 June! -)
