The aim of this study is to develop an integrated scientific and mathematical model that is suited to the background of Turkish teachers. The dimensions of the model are given and compared to the models which have been previously developed and the findings of earlier studies on the topic. The model is called the balance, reflecting the significance of balance in the process of integration. The balance model includes five dimensions: content, skills, the teaching-learning process, affective characteristics, measurement and assessment. The goal of the balance model is to keep the content/standards the same as their original values.
