Popis: This paper discusses the construction of hints for mathematical problems and their effectiveness. From a set of 15 non-standard problems on functions every problem was presented to a hundred ninth-grade students (age about 15). Hints might be used if necessary. Hint effectiveness was studied as a function of hint characteristics. The following results were obtained: Hints which stimulate concrete action are effective, if the action serves as a model for the required solution method. Hints which give only warnings against certain mistakes are ineffective. Hints which show a great part of the solution of a problem seem to be effective; however the solution was often reached with lack of understanding. The results are compared with results obtained by Trismen (1981, 1982).
