knowledge Early biology students
Eureka Education - Learning Biology is closely linked to the learning theory of constructivism. "Constructivism is the basis of thought (philosophy) a contextual approach is built knowledge gradually expanded the results is limited by the scope (narrow) and not by the sudden (Sagala, 2010: 88)". The link between learning biology with the constructivist theory, based on the nature of life itself can not be separated from everyday life of the students. Thus, students always have the direct contact with diverse object of study Biology. "Based on the direct contact with the phenomenon that occurs frequently, the structure of knowledge will give students meaning in the form of a conception (understanding) of the phenomenon (Saptono, 06: 264)." Understanding is the basis to study the biology, the students understood to have had prior knowledge. So the learning process in biology requires prior knowledge of the students in relation to teaching materials to know biology, which in turn support the performance of learning outcomes were in line with expectations.
ever know the biological process of students at the level of the previous training or experience students in everyday life studies form the basis for the formation of knowledge of students. Because basically, " learning outcomes is determined not only by the environment or the conditions of learning, but students knowledge (Rustaman, 05: 171"). Students' knowledge, it is not necessarily the same from one student to another student. Because basically, the students have their own characteristics.
"The student is a unique organism that develops according to the stage of development. Child development is the development of all aspects of his personality, but the pace and rhythm of development of each child in all respects not always the same (Sanjaya, 2010: 17) ".
The learning process can be influenced by a child's development are not the same, inherent in children in addition to other features. Therefore possessed knowledge was certainly different, received due to the differences in the pace of development of the pupils or and interpret differences in the learning process.
In addition to one of the bases used for the achievement of learning outcomes , initial knowledge of students who have been identified, be to diagnose the abilities and needs in students learn . Since the task of the teacher in the learning process, not only as an information center, but pendiagnosis and promoter of learning.
Accordingly, it is understood that the identification of the initial knowledge of the students is what to take note of the process study biology become. "Teachings will be successful if they start from what is already known by the learner. This means that teachers need to know in advance the knowledge and behavior that is by learners possession, both knowledge and experience in the broadest sense and the knowledge and behavior of the prerequisite for the next teaching material (Rohani, 04: 171). "
Because students knowledge by identifying the learning process will be tailored to the student's capacity. Thus, results of learning that the goal will be easier to achieve. "Because often encountered in the development of learning Biology to discuss teachers the material directly, which has been prepared. Rarely do the teachers have to learn by exploring the students initial knowledge in the subject began in discussed a structured. If teachers do a pre-test at the beginning of learning led, the tests were reluctant to compare the results of pre-test after the test, are carried out after learning not to know things or concepts that have understood the students who may still wrong and needs during the learning process (Saptono, 06: 264-265) to be repaired. "
Education biology in school is associated with a variety of concepts, facts and theories, which are all interconnected. So overall, it should be understood as a whole. Moreover, the complex biology teaching materials and mutual berkaiatan, thereby causing the need for a firm understanding of the basic material, which will be the basis for the entry of the next material. The identification of prior knowledge students, the occurrence of misconceptions learn .
