CHAPTER I
INTRODUCTION
1.1 Problem Background
Mathematics is very important for given to all levels of education,
including in Junior High School to equip learners with the ability to think
logically, analytical, systematic, critical, creative, and have a good personality, so
that students will be able to solve problems in almost all fields of life. And be able
to face the challenges of life ahead.
Learning mathematics is a conscious effort to gain understanding,
relationships and symbols, and then apply the concepts generated into a real
situation. The one of purpose of learning mathematics in Junior High School is the
concepts understanding. Because algebra is one of part from mathematics then
understanding of algebra concepts is one of purpose that will achieved in
mathematics learning for Junior High School and the same level. Introduction of
concepts algebra need given to students, because its concepts will useful in
various mathematics fields that will be learned by students.
“Algebra is languages of symbol and relation”.(Johnson and Rising, 1972:3). This thing also stated by Krismanto (2009:1) about algebra, he said that:
Aljabar digunakan untuk memecahkan masalah sehari-hari. Dengan bahasa symbol, dari relasi-relasi yang muncul, masalah-masalah dipecahkan secara sederhana. Bahkan untuk hal-hal tertentu ada algoritma-algoritma yang mudah diikuti dalam rangka memecahkan masalah simbolik itu, yang pada saatnya nanti dikembalikan kepada masalah sehari-hari. Jadi belajar aljabar bukan semata-mata belajar tentang symbol atau keabstrakannya, melainkan belajar tentang masalah sehari-hari.
And the other definition of algebra namely algebra is a generalize form of
arithmetic, and for the purpose of generalization of arithmetic, letters and signs
are used. No doubt, the use of letters and signs that makes an abstract subject.
Because of the nature of generalization and abstraction, algebra is considered to
2
Students experiences difficulty in learning mathematics, namely because
strategies or teaching methods are less appropriate to the material being taught
and students is not understanding the mathematical concepts well, the one of them
is algebraic concepts.
The use of conventional learning makes students can’t develop their creativity, make students tend to get bored and this method makes the student
activities is low because in here teacher actively involved in the learning process,
the students just sitting, listening, taking notes and doing solve the problems. This
is the reason why the students lack of respect to the teacher when the teacher was
explained, they tend not to pay attention, and preoccupied with their own
activities, such as talking with their friends, or doing work that is not relate to the
lesson.
Selection of good method of teaching and appropriate for students is
important because in addition to realizing the objectives of the study also can
increase the activity and students learning achievement.
Based on the diagnostic test that conducted in grade VIII-3 of SMP Negeri
1 Binjai in topic of algebraic operations obtained that many students couldn’t
show which one is coefficient, constant and like terms from algebraic expression.
Like the picture below.
Figure 1.1 Student Mistake in Diagnostic Test Item 1
By looking the answer of student above, student solve the problem by
doing operation of addition and subtraction to get the simply form of the algebraic
expression but it’s not a solution of that question. Students often do mistakes in
3
Figure 1.2 Student Mistake in Diagnostic Test Item 2
In the picture above student still false in calculate 4x – 2x is 2x, but the
student wrote 6x and it’s not true. Students don’t know multiplication signs like
negative time’s negative is positive, positive time’s negative is negative and so on.
Like the picture below.
Figure 1.3 Student Mistake in Diagnostic Test Item 2
From the answer of student above, appear that student didn’t know product
of ( – ) × (–4x2 + 2x + 7) and student appear still confuse to how solve the
problem because there are mistakes in every step of solve the problem. And also students couldn’t solve the multiplication of algebraic expression. Like the picture below.
Figure 1.4 Student Mistake in Diagnostic Test Item 3
Based on the answer of student above appear student couldn’t multiply the algebraic expression, student conduct addition to solve multiplication in the
algebraic expressions. Student should use distributive law in the multiplication
that ever learned in grade VII to solve that problem.
If the basic knowledge of this algebraic expressions they don’t master,
4
namely one of them is algebraic operations and this things will impact to their
learning achievement in mathematics. Certainly, the learning achievement will be
low.
This is consistent with the results of interviews conductedwith one of the
mathematics teacher in SMP Negeri 1 Binjai, obtained information that students
learning achievement in mathematics about algebraic operations are low. There are students who didn’t understand the material well. This is due to the lack of students participate actively in the learning process. Students also didn’t
understand well about definition of variables, constants, term, coefficients of term,
like term and unlike term. And students didn’t master the material prerequisite of
algebraic operation namely integer operations, fractions and algebraic expression
that have learned in grade VII. So, the students in grade VIII-3 still are having
difficulty for solve the problem of algebraic operations.
Thus, it can be concluded that the low of student activities is influenced by
the learning model used, certainly students learning achievement also will be low.
If the learning model used does not match then it will affect the student activity
and the learning achievement. To overcome all of that, the role of teachers in
creating innovative and effective learning is very required.
The creation of effective teaching and learning need to pay attention of the
learning strategy that exact in order to achieve the maximum results. To overcome
the problem difficulty to students in grade of VIII-3 SMP Negeri 1 Binjai in
learning algebraic operations, researcher will implement the learning strategy to
improve student activities. Learning strategy that applied in this study is Relating,
Experiencing, Applying, Cooperating, and Transferring (REACT).
Steps of REACT learning strategies reflected from its acronym. These
steps are Relating, Experiencing, Applying, Cooperating, and Transferring.
According to Crawford (2008:3-14) states that:
5
we define as using knowledge in a new context or novel situation-one that has not been covered in class.
The learning process in the Education Unit Level Curriculum requires the
active participation of all students. Thus, student-centered learning, the teacher as
a motivator and facilitator in it so that the classroom atmosphere more lively. In
this study the researchers will use learning media such as power point about
algebraic operations that will attract students to learn actively and also student
worksheet that will become a guide for students to do group activities, so that the
working group focused and can achieve the learning that desired.
Based on the background that has been described above, the researcher is
interested in doing research with the title: "Implementation of REACT Strategy
to Improve Student Activities in Grade VIII-3 of SMP Negeri 1 Binjai”.
1.2 Problem Identification
Based on the background of the problems described above, can be
identifying a number of problems:
1. The low of student activities caused by teacher often use the conventional
learning model that makes students become bored during the learning
takes place so that its impact to students learning achievement.
2. The low of student learning achievement in mathematics subject because
mathematics is still considered as a difficult subject.
3. Students have difficulty in understanding algebraic concepts.
4. In learning mathematics teacher still dominate the class.
5. Implementation of the learning model used in teaching mathematics is still
less precise.
1.3 Problem Restriction
In accordance with the background and the identification of the problems
above, so need for make a problem restriction to more be focus and be directional.
6
improve student learning activities in the topic of algebraic operations in grade
VIII-3 of SMP Negeri 1 Binjai.
1.4 Problem Formulation
Based on the background of the above problems can be formulated as
follows:
1. Is there increasing of the student learning activities during learning
mathematics with the implementation of REACT strategy?
2. Is there the relationship between student learning activities with student
learning achievement after implement REACT strategy in the topic of
algebraic operation?
3. How does student respond to the implementation of REACT Strategy in
the topic of algebraic operation?
1.5 Research Objective
The objective of this research is:
1. To know the increasing of the student learning activities during learning
mathematics with the implementation of REACT strategy.
2. To know the relationship between student learning activities with student
learning achievement after implement REACT strategy in the topic of
algebraic operation.
3. To know the student respond to the implementation of REACT strategy in
the topic of algebraic operations.
1.6 Benefits of Research

learning mathematics in school.
4. For researchers, as an information and as a material grip for researchers in
carrying out the teaching duty as prospective teachers in the future.
5. As a matter of information to readers or other researchers who want to
CHAPTHER V
CONCLUSION AND SUGGESTION 5.1 Conclusion
1. There is increasing of the student activities during learning mathematics with the implementation of REACT strategy namely 20,11 %. By using increasing criteria of student activity, the increasing is classified into medium category.
2. There is the relationship between student activities with student learning achievement after implement REACT strategy in the topic of algebraic operation namely we can see in cycle I obtained average of student activity score is 17,74 or 17,15% with the category is Inactive student whereas average score of student learning achievement in cycle I is 69,84 with percentage of student complete is 69,57%, this result not satisfy criteria of completeness student learning achievement. And in cycle II obtained average of student activity score is 19,61 or 81,70% with category is active student whereas average score of student learning achievement in cycle II is 80,46 with percentage of student complete is 86,96%, this result satisfy criteria of completeness student learning achievement. It means that activity have relationship with student learning achievement, activity is not increase then the student learning achievement is not increases too and activity is increase then the student learning achievement is increases too.
3. Student respond to the implementation of REACT Strategy in the topic of algebraic operations is good. This result, obtained from the average score of student responses is 69,87 (82,20%) and it is classified into good category. It means, students think that REACT strategy is good and interesting learning strategy that can increase their activity and their student learning achievement in learning process.
5.2 Suggestion
74
2. For student, expected to use REACT strategy in learning that they are expected to be able to think independent, to be able to discuss with friend and to be able in sharing their opinion/idea in front of class.
