Additional Structured Discussion Boards:
Structured Discussion Boards
- Argumentation, is quite different from normal "social chatter" and written assignments.
Three notable systems:
Belevedere
- Belvedere, according to Jonassen, provides conversation nodes
- hypothesis, data, principle, and unspecified
- for, against, and "and"
This is quite interesting because it seems sort of like a science project, a sort of trial and error situation. Thinking that these model and technological learning is linked to conceptual change as a part of trial and error. Hence, theories and processes not always true and can be altered in the future. Thus in conclusion it is always important and relevant to continue and keep on learning.
- in the Belvedere program, when students respond they must indicate response type. a question, a comment, a rebuttal, an alternative
Not only does this type of collaboration involve personal responses, however, the learner is gaining knowledge of argument types, such as a question, a comment, a rebuttal. This then becomes nature to ask a questions, comment, rebut and add alternatives effectively without repose or poise in normal conversation or educational social settings. Thus, argumentation becomes healthy and adds to our well being! That being said, the question, would you like to argue today, might simply mean, would you like to learn today?
Further in the section Jonassen discussed a more structured discussion board idea. Wherearguments are to at times be presented with factual information in order to be considered valid or invalid arguments.
Convince Me (www.convinceme.net)
Using Convince Me, students can:
(1) articulate beliefs about a controversy
2) Categorize each belief as either evidential or hypothetical;
(3) connect their beliefs to support or reject a thesis;
(4) provide ratings to indicate the believability of each statement; and
5) run connectionist simulation that provides feedback about the coherence of their argument.
Because of this type of feedback Convince Me is considered as one of the most powerful argumentation tools available.

Message types
- Solution proposal,
- Reason to Support,
- Reason to Reject,
- Modify Proposal,
- Information of Facts,
- Personal Opinion or Belief,
- Personal Experience,
- Research Findings.
Each message type is of course defined by the instructor. Then the instructor specifies the relationships between message types.
Four types of statements in four levels: each level is represented by message types.
- problem,
- proposal,
- warrant, and
- evidence
At the problem level the instructor post a problem level statement.
Problem level statements can only be responded with proposal-level statements--
(Solution Proposal).
Solution proposals can only be responded with warrant-level statements--
(Reason to Support,
Reason to Reject,
Modify Proposal).
Warrant-level statements can only be responded with evidence-level statements--
(Information or Facts,
Personal Opinion or Belief,
Personal Experience,
Research Findings).
Modelling with Structured Discussion Boards:
Modeling With Structured Discussion Boards
Discussion boards are not normally considered modeling tools. However, when students use constraint-based discussion boards, models of collaboration are built and created verbally. Thus, though the discussions are visual and most of the discussion is verbal Jonassens argues that discussion boards are considered a modeling tool.
Coaching the use of Structured Discussion Boards
Jonassen has created and provided for us a model upon which to follow when facilitating or moderating a structured discussion. "Teachers as moderators of structured discussion boards need to be coaches, not sources of knowledge." (Jonassen, Modeling with Technology, p. 201)
- Assure students that they can really communicate with the system. Motivating learners and overcoming phobias and anxieties is a critical process. Welcome each new user to the conference.
- Ensure that learners have access to the computer network through directly-connected computers or computers with modems so they can log on frequently.
- Provide active leadership. Start by playing host: Welcome participants to the conference and establish a nonthreatening climate.
- Periodically summarize the discussion and make sure that it does not drift off the theme or become too fragmented. Ask participants for clarification of their ideas; resolve dispute or differences in interpretation.
- periodically prompt nonparticipants to contribute ideas or reactions to the conference and reinforce their initial contributions. You may want to send students private mail that provides feedback or other interpretations.
- Periodically ask engaging questions or submit issues that can clarify ideas or become a new focus for discussion.
Coaching with Discussion Boards
- Ask Engaging Questions
- Prompt Non-Participants
- Summarize the discussion
- Provide Active Leadership
- Ensure Access
- Assure students
Evaluating Structured Discussion Boards:
Evaluating Structured Discussion Boards
- Evaluate the quality of contributions. (Quality valued rather than Quantity)
Quality of student messages
Low
Student messages confusing and disconnected;
contain hearsay,
unsupported remarks,
and personal beliefs
High
Students messages contain clear communication,
are supported by evidence,
represent accepted theories
Coherence of student messages
Low
Student messages not related to discussion topic,
redundant,
repeat other views;
irrelevant comments
High
Student messages explain issues,
provide new perspective,
make significant contribution to discussion,
elaborate on existing comments
Accuracy of student messages
Low
Student messages misclassified:
do not represent constraints consistently
High
Student messages consistently represent the
constraint imposed by the discussion board.
Relevance of student responses to messages
Low
Student responses irrelevant,
do not address issues;
non sequiturs
High
Student responses elaborate,
contradict,
modify, or relate specifically to previous message
This rubric above is provided in the text "Modeling with Technology," by Jonassen on page 203, Figure 17-4. He describes it for use when evaluating student contributions in asynchronous computer conferences.

Evaluated Student Contribution:
- Quality: Student messages contain clear communication, are supported by evidence, represent accepted theories.
- Coherence: Students messages explain issues, provide new perspective, make significant contribution to discussion, elaborate on existitng comments.
- Accuracy: Student messages consistently imposed by the discussion board
- Relevance: Student responses elaborate, contradict, modify, or relate specifically to previous message.
Advantages and Limitations:
Advantages:
Networked computers are a great agent for propagation and dissemination of social skills (locally, regionally, nationally and internationally).
More interaction and involvement in computer conferences than face-to-face interchanges. Conferences reduce personal fears because of anonymity.
Are likely to enhance effectiveness of collaboration efforts by: improving access to other group participants, eliminating social distinctions and barriers between participants, contributing to a sense of informality, and fostering a stronger group identity.
Students may do their work when it is convenient or when they are most alert.
Students may argue a disagree without being involved in excessive conflict.
Discussion boards support collaborative learning.
Enhances the writing of apprehensive and nonapprehensive writers. Effective means for teaching collaborative problem solving and other tasks
Computer conferencing shows instructor contributions to be 10% to 15% of message level. This allows learners to generate questions, summarize content, clarify points, and predict upcoming events.
Disadvantages:
Users must be skilled as communicators; They need facility with the languages.
Users must be moderately skilled typists.
Times zones may delay conversations and may reduce impact of messages or feedback
Technophobia or communication anxieties may prevent individuals from participating. "Lurkers"
Anonymity may increase, rather than diffuse, anxiety
Conferencing may amplify social insecurities.
Absence of social context cues can make discussion more difficult.
Hardware and communication lines and equipment are not 100% reliable (loss of work, delay of communication).
