The systems are sold as packages, incorporating both the hardware and software for setting up a computer lab. ILS developers have also made a point of developing systems that tie into the major basal textbooks. Users of ILSs enjoy the advantage of having one coordinated system, making it easy for students to use a large selection of software. A new trend in integrated learning systems is represented by ClassWorks , developed by Computer Networking Specialists. Most instruction occurs in groups of 25 to 35 students in small segments from 45 to 50 minutes long.
Instruction is usually either whole-class or completely individual.
Instruction is teacher dominated, with teachers doing most of the talking and student talk confined largely to brief answers to teacher questions. When students work on their own, they complete handouts devised or selected by the teacher. Students have little responsibility for selecting goals or deadlines and little chance to explore issues in depth. Most responses are brief. Knowledge is represented as mastery of isolated bits of information and discrete skills.
