What is unique about the computer?

• Ability to manipulate data to represent knowledge
• Ability to manipulate variables in a microworld
• Removal of time and geographical barriers
• Increased access to information

2
Spreadsheets

• Collect and analyze lab data
• Experiment with what if scenario
• Create the spreadsheet for data collection
• Create what if scenario

3
Databases

• manipulate data
• look for relations
• ask questions
• create a database

4
Concept Mapping
5
Simulations/Models

• a constrained environment that allows learners to
  test hypotheses
• provides experiential learning
• allow the exploration of phenomena
• learners can build their own models
• E.g. Gizmos
• Class Code NCZNT4LPRL

6
Multimedia

• Allows students to represent knowledge using a
  variety of media
• Not restricted to a linear representation of
  knowledge

7
Electronic Communication

• Extends the boundaries of the classroom
• Learners can communicate with experts in the
  field
• Learners have time to reflect before responding

WebQuests in Science

• Information in this presentation adapted from
  Kathleen Schrocks slide show available at
  http//school.discovery.com/schrockguide/webquest/
  wqsl1.html

What is a WebQuest?

• An problem solving, decision making or
  inquiry-oriented activity in which some or all of
  the information that the students interact with
  comes from resources on the Internet.

10
Two Types of WebQuests

• Short Term designed to be completed in one to
  three class periods.
• Long Term designed to be completed in one week
  to one month.

11
WebQuest Components

• Introduction
• Task
• Procedure
• Resources
• Assessment or Evaluation
• Conclusion
• See 2Learn site for an alternate format.

12
Other WebQuest Components

• Incorporates group activities
• Includes role-playing for learners
• Single discipline or interdisciplinary

13
Introduction

• Orients the learner to what is coming.
• Raises some interest in the learner through a
  variety of means.

14
Task

• Includes a description of what the learner will
  have done by the end of the activity.
• The task could be a product, verbal presentation
  or a combination of both.

15
Procedure

• Contains clearly described, numbered steps.
• Identifies to the learner the process to go
  through to accomplish the task.
• Can also provide learning advice.

16
Resources

• Includes a list of Web pages which the instructor
  has located that will help the learner accomplish
  the task.
• May include resources not available on the
  Internet, such as textbooks, newspaper/magazine
  articles and videos.
• Not all resources will be used by all.

17
Assessment or Evaluation

• Used to measure results from the task and also
  the learning process.
• Rubrics designed by the teacher will be the most
  authentic assessment.
• Rubrics can take different forms.

18
Conclusion

• Brings closure to the activity.
• Reminds the learner about what theyve learned.
• Encourages the learners to extend the experience
  into other domains.
• Can ask for personal reflection.
