The Development of Academic Supervision Learning Material for the Education and Training of Prospective School Principal Preparation Program
The objective of this research and development is to arrange an academic supervision learning material for the education and training of School Principal Preparation Program that can support or improve the supervisory competency dimensions owned by the participants of the education and training of Prospective School principal Preparation Program so that they can implement the supervision well. This research employed the R esearch & Development (R & D) approach with the following phases: (1) introduction phase which was done through field survey in Karanganyar regency of Central Java province, Jeneponto regency of South Sulawesi province, and Gunung Kidul regency of Yogyakarta Special Region province and which aimed at invsetigating the problems encountered in the use of academic supervision learning material for the education and training of Prospective School Principal Preparation Program; (2) development phase which included the design and development of learning material, experts’ validation, and limited experimentation in Bangka regency of Bangka Belitung province as well as extended experimentation in Blitar city of East Java province and which aimed at attaining the product of a set of learning material already developed and ready for use in education and training of prospective school principal preparation program; and (3) evaluation phase, in which  Effectiveness Test 1 was conducted in Malinau regency of East Kalimantan province and Effectiveness Test 2 was held in Magelang regency of Central Java province; both of which aimed at testing the reliability of the attained product, that is, measuring the effectiveness level of the academic supervision learning material. The findings of the field survey show that a further development on the academic supervision learning material for the education and training of Prospective School Principal Preparation Program is required as indicated by the result of the quantitative data processing with the average index of 2.15, which is in the less good category. The development phase produces a set of academic supervision learning material for the education and training of Prospective School Principal Preparation Program, which consists of Design and Construction of Education and Training Program, lesson plan, and slide material which is used in the education and training of Prospective School Principal Preparation Program. The average score of product validation in the aspect of material substance is 4.75, which is in the good category and that of product validation by media experts is 4.32, which is in the good category. The limited experimentation shows that average score of the education and training participants’ achievement increases up to 9.895. Meanwhile, the extended experimentation shows that that average score of the education and training participants’ achievement increases up to 23.636. Effectiveness Test 1 and Effectiveness Test 2 show that there is a significant difference in the final ability of the control group and the experimental group. The average score of the students using the developed academic supervision learning material is higher than that of the students using conventional one as indicated by the average score of the conventional one that is 12.325. Thus, the results of the use of the developed learning material can support the academic supervision competency dimension owned by the prospective school principals particularly in improving the conceptual skills of academic supervision of the participants of the education and training of Prospective School Principal Preparation Program.
