Problems in the Classroom Action Research (PTK) is the low learning outcomes IPA A fourth grade students of SDN 015 Sungai Salak Kecamatan Tempuling. This study addressed the problem by applying direct instrucsion models. The problem of this research is "Is the direct application of the model intruction IPA can improve learning outcomes in grade IV A SDN 015 Sungai Salak Kecamatan Tempuling ?. The purpose of this study is to improve science learning outcomes in class IV A SDN 015 Sungai Salak Kecamatan Tempuling by way of direct intruction models. Direct intruction A model of fourth grade students of SDN 015 Sungai Salak, Kecamatan Tempuling can improve learning outcomes significantly. At first the student learning outcomes pre-cyclye is 36.00 categorized as very unfavorable; in the first cycle was 61.00 with category; and the results of the second cycle is 81.50 with very good category. Mastery learning individually and classical increases; pre-cyclye 4 students and 20.00 (not finished); in the first cycle is 12 students and 60.00% (not finished) and the second cycle is 19 students or 95% (complete). Based on observations of fourth grade students of SDN 015 A Sungai Salak Kecamatan Tempuling, activity in the first cycle an average of 72% or better and the second cycle of activity is 82% or better at all. Students seem to understand the direct intruction models and they can understand the subject matter properly and appropriately. Based on the research results with direct instructional improvement intruction models managed to fix the problem of low student learning outcomes SDN 015 class IV A Sungai Salak Kecamatan of Tempuling.

Based on the author's experience teaching for this in SD Negeri 010 Banjar PanjangKerumutan, and based on observation and early reflections by the author seen low creativityof students in learning that ultimately ends up in the low student learning outcomesthemselves, especially on the subjects of Natural Sciences. After many tests on the midtermturns lower student learning outcomes. Completeness class only reach 50% or 10 out of 20students, KKM for subjects of Natural Sciences which has been set in the class IV SD Negeri010 Banjar Panjang Kerumutan is the number 70. As Judge things that cause children lowvalue, from the aspect of teachers are: teacher always using methods lectures, learningachievement of children have been considered equally by teachers, and the learning processis dominated by the teacher. This research is a classroom action research (PTK). Class actionresearch through the stages of planning, implementation, observation and reflection.
