The objective is to review the curricula for Science and Technology Teaching I and II courses included in the Undergraduate Programs for Primary School Teachers in Turkish Faculties of Education, with reference to their objectives, contents, learning-teaching process involved, and the assessment procedures, and to come up with a curriculum proposal for these courses. The data obtained through case study were reviewed through descriptive analysis. Through the study which commenced in 2013, it was observed that a definite curriculum did not exist with respect to Science and Technology Teaching I and II courses, and that the curricula implemented by the teaching staff as part of the Undergraduate Program for Primary School Teachers failed to meet the requirements expected of the prospective primary school teachers. In this context, the researchers developed a Curriculum Proposal for Science-Teaching Courses in the Undergraduate Program for Primary School Teachers. The curriculum designed with the implementation of Demirel's DEPGEM model, for Science-Teaching I and II courses is based on a progressive education philosophy emphasizing a constructivist approach and student-centric education. The Science-Teaching Curriculum thus designed entails the statement of 13 objectives and 80 learning outcomes with reference to cognitive, affective, and psycho-motor aspects, as well as 15 topics and their sub-headings in line with the objectives, along with 17 principles regarding the learning-teaching process and 13 principles regarding the assessment process.
