The purpose of this study was to develop a likert-style scale, reliable and valid for the use of mathematics in operational physics and chemistry problems. Before developing the scale, the current scales had been carefully analyzed, the views of experts were taken, and the first draft of scale was prepared. The validity and reliability studies of the scale were carried out by applying the first draft on 434 students. The total item and remainder item correlations, item discrimination, factor analysis and internal consistency measures were respectively implemented on the scale for a deeper validity and reliability analysis. According to the results of the analysis, the scale had two subscales. Cronbach Alpha coefficients were calculated for all subscales as 0.720, 0.675 respectively and for whole scale as 0.713. The value of Kaiser-Meyer-Olkin is 0.679 and Barlet's value is 936.859. As a result, it can be concluded that the developed scale is a valid and reliable instrument for the use of mathematics in operational physics and chemistry problem solving and is likely to contribute to literature on this subject.
