Computer-assisted instruction (CAI)
The computer can be a tutor in effect relieving teacher of many activities in his personal role as classroom tutor. It should be made clear, however, that the computer cannot totally replace the teacher since the teacher shall continue to play the major roles of information deliverer and learning environment controller.
The teacher in CAI plays its own role:
▪ Insure that students have the needed knowledge and skills for any computer activity
▪ Decide the appropriate learning objectives
▪ Plan the sequential and structured activities to achieve objectives
▪ Evaluate the students’ achievements by ways of tests the specific expected outcomes.
The student in CAI play their own roles as learners as they;
▪ Receive information
▪ Understand instruction for the computer activity
▪ Retain/keep in mind the information and rules for the computer activity
▪ Apply the knowledge and rules during the process of computer learning
During the computer activity proper in CAI the computer too plays its roles as it:
▪ Act as a sort of tutor (the role traditional played by the teacher)
▪ Provides a learning environment
▪ Delivers learning instruction
▪ Reinforces learning through drill and practice
▪ Provides feedback
CAI Integrated with Lesson
CAI computer learning should not stop with the drill and practice activities of students in effect, CAI work best in reinforcing learning trough repetitive exercise such that student can practice basic skills or knowledge in various subject areas. Common types of drill and practice programs include vocabulary building, math facts, and basic science, and history or geography facts. In these programs, the computer presents a question/ problem the first and the student is asked to answer the question/problem. Immediate feedback is given to the student’s answer. After the number of practice problems and at the end of the exercise, the students get a summary of his overall performance.
The question arises: When and how can teacher integrate drill and practice programs with their lessons? The following suggestion can be made:
▪ Use drill and practice programs for basic skills and knowledge that require rapid or automatic response by students (e.g. multiplication table, letter and word recognition, identification of geometric shapes, etc.) ▪ ▪ Ensure that drill and practice activities conform to the lesson plan/curriculum.
▪ Limit drill and practice to 20-30 minutes to avoid boredom.
▪ Use drill and practice to assist students with particular weakness in basic skills.
In integrating computer programs in instruction, use tutorial soft ware associated with cognitive learning. While practice exercise or learning by doing is still the heart of each tutorial, the tutorial software should be able to:
▪ Teach new content /new information to students (in as much as CAI provides practice on old or already learned content)
▪ Provide comprehensive information on concepts in addition to practice exercise
▪ Can be effectively used for remediation, reviewing or enrichment
▪ Allow the teacher to introduce follow-up question to stimulate student learning.
▪ Permits group activity for cooperative learning
SIMULATION PROGRAMS
Simulation software materials are another kind of software that is constructivist in nature. This simulation software:
▪ Teacher strategies and rules applied to real-life problems/situation
▪ Ask students to make decision on models or scenarios
▪ Allow students to manipulate elements of a model and get the experience of the effect of their decisions
An example of such software is SimCity in which students are allowed to artificially manage a city environment. Decision-making involve such factors as budget, crime, education, transportation, energy resources, waste disposal, business/ industries available.
Instructional Games
Instructional computer games add the elements of competition and challenge.
An example is GeoSafari which introduces adventure activities for Geography History and Science. The program can be played by up to four players to form teams. Learning outcomes can be achieved along simple memorization of information, keyboarding skills, cooperation and social interaction.
PROBLEM SOLVING SOFTWARE
These are more sophisticated than the drill and practice exercises and allow students to learn and improve on their own problem solving ability. Since problems cannot be solved simply by memorizing facts, the students have to employ higher thinking skills such as logic, recognition, reflection, and strategy-making
The Thinking Things 1 is an example of a problem solving software in which the team learners must help each other by observing comparing.
MULTIMEDIA ENCYCLOPEDIA AND ELECTRONIC BOOKS
The Multimedia Encyclopedia can score a huge database with text, images, animation, audio and video. Students can access any desired information, search it vast contents and even download/print relevant portions of the data for their composition or presentation. An example is the eyewitness children’s encyclopedia.
Electronic books provide textual information for reading, supplemental by other types of multimedia ( sounds, pictures). These are useful for learning reading, spelling and word skills. Example are Just Grandma and Me story book which offer surprises for the young learner's curiosity.
Reflection:
Computer as a Tutor one of the uses of computer and several advantages that can achieved like we can used in every day teaching when we become a teacher but computer as a tutor in this new of age.Integrating computer exercises is the new task of the teacher who can find the computer software an alternative medium to the traditional learning classroom practice of delivering information and supporting learning activities. Computer in school as a common tool for enhancement of the student's thinking, communication and collaboration skills and it does not replace the teacher, although it assumes certain roles previously assigned to teachers but teachers should not depend the learning of the students on the computer, the new role of the teacher is to facilitate.
Use the computer in a proper way.....
