USING WORKED EXAMPLES AS AN INSTRUCTIONAL EXAMPLES AS AN INSTRUCTIONAL SUPPORT IN THE ALGEBRA CLASSROOM

In the 2 experiments reported here, high school students studied worke d examples while learning how to translate English expressions into al gebraic equations. In Experiment 1, worked examples were used as part of the regular classroom instruction and as a support for homework. In Experiment 2, students in a remedial mathematics class received indiv idual instruction. Students using worked examples outperformed the con trol group on posttests after completing fewer practice problems; they also made fewer errors per problem and fewer types of errors during a cquisition time, completed the work more rapidly, and required less as sistance from the teacher.
