Scaffolding in problem-based learning for low-achieving learners

ABSTRACT

This research investigates scaffolding approaches for supporting low-achieving learners in a problem-based learning environment. The study was conducted in a vocational school with 3 different approaches to scaffolding using 3 groups in addition to a control group. The area of focus was a learning module using computer spreadsheets. The results showed that there was a significant difference in outcomes among the 4 groups. The group that used a semicollaborative approach combined with worksheet performed significantly higher on posttests than the other group. This study illustrates the value of scaffolding for low achievers in problem-based learning environments and identifies the specific type of scaffolding that is most effective.
