Abstract

The aim of this study was to implement and evaluate the instructional design prepared as consumer-oriented and based upon interdisciplinary curriculum. In this study, case study approach, which is one of the qualitative research patterns, was employed. Observations, interviews and document analysis were used to collect data. For analyzing the data, inductive and deductive content analysis methods in the scope of the content analysis were used in combination. Consequently, it was indicated that instructional design which was developed with an interdisciplinary approach contributed to gain interdisciplinary knowledge and skills and develop consumer consciousness. In the light of these results we may conclude that this design is implementable. However, it was clear that the students had difficulties in points such as performing mathematical operations and expressing warrants. These situations made the implementation process more difficult. These results will contribute to the development of various approaches in mathematics instruction and the diversification of the implementations regarding mathematics use in real life.
