Selection of appropriate learning approaches and strategies, will facilitate the achievement of these learning activities. Similarly, in mathematics learning activities in PGSD (department of elementary school preservice teacher), which is demanding the development of a high level of mathematical ability as well as critical thinking skills. However, not many people are trying to look for other factors in addition to the approach/learning strategy, which is possible to contribute to the development of critical thinking skills, such as interest factor majors students (IPA [science] and non-IPA [non-science]) as well as mathematical prior knowledge which has been owned previously. In addition, affective aspects that accompany any critical thinking skills (critical disposition) is a study that is still rare. This paper briefly present to peel the election factor of approaches and learning strategies, ie, problem based learning with "MURDER" strategy, shared interests and their interaction majors and mathematical prior knowledge of the result of performance of critical thinking skills and dispositions of PGSD students.

A knowledge is the result from students' self-construction idea, which makes more meaning full of learning process. Sometimes, teachers forget to elicit students’ life experience as their prior knowledge. If this prior knowledge exposed, student will be easily received the new idea, because the students indirectly build their own knowledge. The constructivism point of learning is a teaching and learning process in such a way will make students are mentally active in construct their own knowledge, based on their cognitive structure. It must be considered how the children forming their concept in cognitive structure as the acquisition in geometry concepts. Knowing of the geometry formulas is not a guarantee that the student has thoroughly been learning about the geometry concept. On the other hand, the formula of rectangles’ area is not come instantly, but it can be reformulated by the construction of students’ prior knowledge. I brought them in a specific activity that makes them enjoy and vigorously; students are directed to find a rectangles’ formula.

The purpose of this research is to improve ecoliteracy students through field-trip method of the impact upon economic activity in the form of waste tahu. This study uses observations in the form of the method field-trip to the factory tahu and the school environment. The method used in this research is Classroom Action Research (classroom action research) in the fourth-grade students of SDN Lembur Situ , North Sumedang. Ecoliteracy indicator of this research is to use an indicator of Thomas Lickona (2012) in which there are knowledge aspect, awareness and application. The research instrument used was direct observation of a student observation sheets, questionnaires, student worksheets, test tool evaluation and field record sheets were used to obtain data through records in a form and format that checklist done by the author and our partners as an observer. Implementation of classroom action research was conducted three cycles. Results from this study are the increased understanding, awareness and application of students to ecoliteracy.
