Carin (1985) defines science as a system of the universe of knowledge through data collected by observation and experimentation. Meanwhile, Hungerford and Volk (1990) defines science as, (1) the process of testing the information obtained through empirical methods, (2) information provided by a process that uses training designed logically, and (3) a combination of critical thinking process which produce valid information.
Based on these opinions can be concluded that IPA is a collection of knowledge that is systematically arranged in the form of a collection of concepts, principles, theories and laws. IPA can be viewed as a product that is as scientific knowledge gained through scientific methods, and can also be viewed as a process that is a pattern of thinking or method berfikirnya. While the attitude required in the scientific method in the form of a scientific attitude among others curious desire, humility, honest, objective, thorough, critical, diligent, open, and full responsibility.
1. Evaluation of Students
According Yaumil Achir, in Akbar-Hawadi Reni (2001: 39), describes that the focus of child development at age 5-7 years on academic and intellectual world. For this period, which stands out is the number of words, ideas, concepts that represent the things that have been experienced and mentally stored, either through experience or received indirectly.
According to Syaiful Bahri Djamarah (2005:51), students are every person who receives the influence of a person or group of people who run the educational activity.
According to Imam Sutari Barnadib, et al (in Syaiful Bahri Djamarah,
(2005:52), that students have certain characteristics, takni:
1. Not to have a mature moral person so it is still a
responsibility of educators (teachers),
2. Still improve certain aspects of maturity,
3. Having basic human traits emerging in an integrated manner ie biological needs, spiritual, social, intelligence, emotions, ability to speak, members of the body to work, social background, biological backgrounds and individual differences.
2. Thinking Framework
Figure 1. Thinking Framework Chart
Based on Figure 1 can be explained as follows, in the process of thematic learning in teaching science teachers to give a theme. Like the example above, the themes presented are about animals. Based on the theme of the teachers relate it to some other subjects, such as Indonesian, mathematics, religious education and arts and crafts, or can also be connected with other subjects. By doing so, students are expected to think in divergent. Students can train their thinking skills, critical thinking, practice the skills and creativity. So that can add to the knowledge of students, in the same time students can learn several subjects at once, which is expected to increase academic achievement.
3. Hypothesis Actions
The hypothesis of this research is that the thematic learning model
can enhance students’ learning achievement.
a. Research Approach
In this study, the model used is the Collaborative Classroom Action Research model, in which researchers conducted observations in the learning activities of teachers and students in the class.
According to pity Kasbolah (1998:13), classroom action research is one effort the teacher or practitioner in the form of various activities undertaken to improve and and or improve the quality of learning in the classroom. Classroom action research is an activity that directly relates to the duties of teachers in the field. That is, classroom action research is practical research conducted in the classroom and aims to improve existing teaching practice.
According Suharsimi Arikunto, et al, (2007:3), that a class action research and learning activities pencermatan to be a deliberate action that is raised and occur in a class together. The action is given by the teacher or the guidance of teachers by students.
Based on some definitions by experts in the above, it can be
concluded that the definition of the class action are all means
conducted by teachers in the form of action or direction of research activities with the aim to improve and or enhance the quality of learning.
b. Research Design
According to S. Nasution (2006:23), research design is a plan on how to collect and analyze data in order to be economically and harmoniously with the aim of the study.
Research model in this study refers to the process of implementation of the research proposed by Kemmis & Taggart, Suharsimi Arikunto (2007:16-19), which includes the preparation of the draft action (planning), implementation of action (acting), observation (Observing), and reflection ( reflecting).
Activities were visualized in the figure below.

c. Action Development and Assessment Instruments
1. The first round or the first cycle
Before carrying out a thematic learning model planned
several activities, namely:
1) Making learning thematic preparation for teaching science classes II SD.
This activity is carried out to obtain the initial
on thematic learning.
3) Identification of problems in thematic learning
This activity is done in order to know what problems to be faced by students and can determine how to resolve the problem.
4) Determine the manner or method in performing thematic learning.
5) Develop research plan
At this stage researchers are preparing a series of activities
comprehensive form of class action cycle.
d. Actions and observations I
1) The initial stages. Pretest: The teacher asked the students, the question ismentioned three types of living creatures on earth.
2) core activity
a) The teacher shows pictures of animals, animal these are the horses, cows, rhinos, goats, and deer.
b) Students to name the animal.
c) Students calculate the number of animals in the picture.
d) Students color the pictures of animals that had been prepared by teacher.
e) The teacher displays a poem entitled horses.
f) The teacher gives examples of how to read poetry with appropriate intonation.
g) Students read poems together.
h) Some advanced students to read poetry Tesebut with each style.
i) The teacher gives an explanation that as a fellow
