INCREASING UNDERSTANDING STUDENT OF MIDDLE SCHOOL ABOUT THE ELECTRICAL CONCEPT

---

---

PRELIMINARY

Physics is a part of the eye the lesson of Natural knowledge that has Natural phenomena. Many students consider that learning physics is a lesson
which is not fun, full of formula-formula, sitting for hours with pouring attention and thought on a subject, both being submitted by the teacher as well as the ones being faced at the study table, without being accompanied awareness to explore deeper concepts that are can actually add insight or honing skills.

DISCUSSION

Based on the findings of the research outlined in this article looks that learning cooperative type jigsaw can improve Understanding of physics lessons on more electrical concepts increased after proven by observation resultsand can be seen from the increase in the average value the student has understood and understood matter and feel proud of self-confidence so happy to follow the lessons of physics on the concept electricity with good value and increase and reach the standard may exceed the minimum mastery criteria, Jigsaw Cooperative Learning Effectiveness liveliness in following cooperative learning type jigsw electric concept can be done with
full of concentration in following process learning and quietly working on the subject as well as various ideas and cooperation with friends in answering questions including good category and student activity in practice as well as in make the conclusion increased due toactivity that is very effective in following learning when compared with
previous learning.

CONCLUDE

Based on the findings and the results of the analysis
results of data obtained in the field, can besummed up as follows:

1. By using the action of learning co-operative type of jigsaw on the concept of electricity turns out can improve students' understanding of a physics lesson on electrical concepts. Increased students' understanding of electrical physics concept lessons can be proved from result of action of cycle I until cycle IV increasing students' understanding of each
   cycle proves a change in students in terms of following student learning with using cooperative type learning The jigsaw is primarily at the level of understanding.

2. Application of jigsaw type cooperative learning
   on electrical concepts on physics lessons turned out
   very enthusiastic, active and effective can be proven
   from the results of student activities of class IX SMP/MTsS in each cycle and pertained greatly increased as evidenced by the average table-average results of student learning activities and within working with his group is very solid and
   compact.

3. Attitudes and responses of students to learning
   physics on the concept of electricity by using jigsaw type cooperative learning is very fun for students and very passionate and a good positive response in following learning and cooperation with a group of friends so it can understand the concept being taught
   evidenced by a given statement on each students are concerned with cooperative learning type jigsaw and this technique is also felt by students fun and dominant answer yes and agree.

SUGGESTION

1. For the school Schools should provide facilities adequate teaching so that teachers can develop his creation with using various models learning.

2. For teachersTeachers should be able to master wellprocedures to improve students' understanding
   by using cooperative learning jigsaw type.

3. For students With jigsaw type cooperative learning
   is expected to improve understanding students on the concept of electricity.

4. For the Education Office It is hoped that coaching-
   coaching teachers to improve quality of education.
