Recent research has shown that children's errors on arithmetic problems are mostly the result of systematic but wrong procedures. Effective instruction and remediation requires that teachers have substantial knowledge of those incorrect procedures. Being able to diagnose them is therefore an important teaching skill. In the present study a computer program (based on the work of Brown, Burton & VanLehn at Xerox PARC) has been used to train twenty teacher-students in this skill with respect to the algorithms of addition and subtraction. Afterwards a collective diagnostic skill test was administered to this experimental as well as to a control group. Qualitative and quantitative data of this study will be presented.
