THE DIFFERENCE OF STUDENT’S PROBLEM SOLVING ABILITY USING CONTEXTUAL TEACHING AND LEARNING (CTL)

AND DIRECT INSTRUCTION (DI) IX GRADE AT SMP NEGERI 1 MEDAN

Siti Rafiah Rangkuti (ID. Number 408 611 008) ABSTRACT

The purpose of this research is to know whether the difference of students’ problem solving ability using contextual teaching and learning (CTL) and direct instruction (DI) IX Grade at SMP Negeri 1 Medan.

The research was conducted in SMP Negeri 1 Medan using a quasi experiment research on the first semester of IX grade SMP Negeri 1 Medan academic year 2012/2013. Sample was taken by using random sampling; it means that each class had the same chance to be sampled. The sample in this study consisted of two the classes. The first experiment class in IX - Phytagoras was taught by applies Contextual Teaching and Learning (CTL) and the second class experiment in IX - John Locke was taught by applies Direct Instruction (DI). Research instrument in collecting data in this study were a test and an observation sheet. This test was an essay that related to the problem solving essay which was contain of 4 items about surface area and volume of cylinder. Data analysis technique that used was the analysis of difference by using T- test.

Form result of this research gotten the post test average in first experiment class 81.54 and average in second experiment class 68.09. Deviation standard in first experiment class 13.84 and deviation standard in second experiment class is 13.59. After done t-test we get data for tcalculate = 3.177 and t gotten significant

taraf α = 0.05 so ttable = 1.684. According to testing criteria which tcalculate > ttable Ha is accepted means that for post test data 3.177 > 1.684 so Ha is accepted and

also means there is significant difference of problem solving ability of students’

between taught Contextual Teaching and Learning (CTL) and Direct Instruction (DI).

The kinds of mistake that student made after being taught using contextual teaching and learning approach are : wrote not complete information from the problem, wrote wrong formula of surface area and volume of cylinder, wrote not complete strategy to solve the problem, errors in calculation and algebra operation.

The kinds of mistake that student made after being taught using direct instruction are same with contextual teaching and learning, but they did not make re-evaluation correctly.

CHAPTER I INTRODUCTION

1.1 Background

Education is one way to realize quality of society, especially preparing

the excellent society for their competence. However, there are a lot of opinions

the quality of education in Indonesia still low. As Irham Nasution (Waspada

newspaper, February, 2nd 2012) from survey show that our education is far from

the expectation, such as Education for All (EFA) Global Monitoring Report 2011,

which had been launched by UNESCO, was in 65. Then, decreases to the 69 of

127 countries surveyed.

Nowdays, Mathematics is means the unity of knowledge, understanding,

and human skill that are needed effectivelly in modren life. The expectation of

graduate school that was critical, sistematical, reasonable, creative and

cooperative.

There are some reasons concerning learning importance and mathematics

mastery that is important for students. Mathematics belongs to development of

other sciences. It also is relates to the problem solving in daily life. The

mathematics usefulness in daily life such as counting of contents and weight,

collecting, processing, presenting and interpreting data use calculators and

computers. In addition, in order to be able to follow further mathematics, to help

the understanding of other subjects such as physics, chemistry, architecture,

pharmacy, geography, economics, and others. And no expectation to the students

to think logical, critical, and practical, positive attitude and creative spirit.

A lot of articels in newspaper, internet and seminars. The opinion

regarding efforts to improve quality of mathematics education today also there is

no improvement. As the one told by Bahrul and Suhendra (2010:42) that :

(13)

2

Related with condition above that our mathematics education in primary

till junior/senior level just think about numbers. Next, Bahrul dan Suhendra

(2010:42) that:

“Persepsi bahwa matematika adalah kumpulan bilangan yang harus dioperasikan menyebabkan munculnya ketakwajaran dalam konteks matematika yang dibawa ke dalam kelas. Akibatnya, sering kita dengar soal matematika yang terlalu “dipaksakan”, contohnya soal tentang meminta anak menjumlahkan umur suatu planet dengan umur planet lain. Kemudian, keterampilan berhitung ( mental, yaitu tanpa pensil dan kertas) menjadi segala – segalanya dalam pendidikan matematika kita dahulu. Kecepatan berhitung menjadi indicator utama kepiawaian seorang dalam matematika.”

Teaching and learning are two concepts that cannot be separated from

others. Learning show what should be done as a lesson recipient (students), while

teaching shows what should be done by teacher. So, learning is a process of

interaction between teachers and students during teaching process. The successful

of teaching process will be influenced by the ability of teacher to determine

methods and tools is used teaching and also determined by interest of students.

The problem solving ability is low. It is caused some factors between

students, teacher, learning method, or enviroment as related to another. That thing

is as according to statement of Marjohan (2009:13) that : “ The characteristics

conventional teaching is very evident the interaction teacher - students in the

classroom. One of them is oauthoritatian apporoach. Therefore, the students must

have received what teacher saying.”

In addition, mathematics achievement of students also is influenced by

less participation students in classroom. That makes bloced students to solve this

situation. The difficulties of most problem application in mathematics are not lies

calculation, but rather than knowledge how to make clarify problem and can be

solved.

Nowdays, mathematics expectation is facilities students can rediscover

the formula by guide re-inventon. As mathematician discoverer, to find formula

and theory in learning mathematics is problem solving very important. As stated

Tran Vui (in Depdiknas: 2004: 9) Problem Solving is put forth as a major method

(14)

3

Mathematics content standard 2006 for all level education is stated that

aims mathematics (in P4TK 2010:10) that the students should be able to:

a. Understanding mathematics concepts

b. Using reasoning

c. Problem solving

d. Communication of idea

e. Respectful of using mathematics daily life

Furthermore, the importance of problem solving can also be seen in its

role in learning. Stanic & Kilpatrick told McIntosh, R. & Jarret, D. (2000:8), share

the role of problem solving as a context to a few things:

1. To justify the teaching of mathematics.

2. To attract students of the value of mathematics-related contents with real

life issues.

3. To motivate students, arouse students' attention on the topic or procedure

specialized in mathematics by providing contextual usability (inreal life).

4. For recreation, as a fun activity that breaks the atmosphere learning

routine.

5. As an exercise, ability reinforcement concepts that have been taught

directly (perhaps this role most often committed by us during this).

From content standard above, problem solving ability is the important

role in learning mathematics and other subjects. The problem solving ability is

needed everyone formaking decision. Therefore, mathematics teacher expected to

teach prolem solving ability and mastery the concept, and include to reason

critical, sistematical and creative. Indicators of problem solving ability divided

into:

1. Understanding the problem

2. Arrange planning to solve problem

3. Implement the planning

(15)

4

Problem solving process is not about calculation, but rather than on the

knowledge to solve it. Another reason about the low of problem solving in

mathematics of students and commonly for applicable for applied in process of

learning is structural.

Thus, to teach mathematically is mediated problem solving, the teacher

as instructional designer will need to arrange a series of problems that require

mathematics modified responding. Then, the students develop fluency in the

component mathematics skill whom he should be introduced to the next and more

complex math mediated responding.

By existence is expected by structural practice approach is problem

solving be better, one of subject at curved surfaced solids. Students less attention

to the material that is explained by the teacher.It is also found in students’ on SMP

Negeri 1 Medan. Then, the students less understand how to solve it. This

statement also supported by researcher direct interview result with mathematics

teacher in SMP Negeri 1 Medan (Mom Elliati Nasution) April, 3rd 2012 in SMP Negeri 1 Medan stated that : “The students just memorizing the formula . By memorize the formula without understanding well and less practice is difficult to

try the problem related in daily life”.Teacher stated that the students have

problems in learning the cylinder on subtopic which are already entered on a

higher level, namely its application in daily life. The material is a continuation of

the material they have learned at primary school level. However, as mentioned

earlier, because the understanding of concepts in elementary school is still lack, so

the students will into this subtopic in their junior high school back in trouble.

Mom Elliati also teach mathematics in SMP Negeri 1 Medan express that about

problem solving ability of students is less , it is caused only the students with high

thinking level can using problem solving and another students cannot be done to

solve it.

An approach can be done the teachers in learning process is contextual

teaching and learning approach. The base philosophy of contextual teaching and

learning as new alternative strategy is contructivism. Learning process in not only

(16)

5

contructivism their knowledge. The teacher something to do a assist the students

to get aimed or giving information by teacher.

The contextual is learning approach which learning in the school is related

real situation. Then, the result learning easier is accepted and benefit if the

students leave it the school. By Contextual teaching is related in real situation as

learning source or material application.

According to statement above , a writer as researcher interested to write a

tittle about: “ THE DIFFERENCE OF STUDENTS’ PROBLEM SOLVING ABILITY USING CONTEXTUAL TEACHING AND LEARNING (CTL) AND DIRECT INSTRUCTION IN IX GRADE AT SMP NEGERI 1 MEDAN.

1.2 Problem Identification

Based on brackground of problem, researcher identify various problems as

follows:

1. Problem solving ability in mathematics of students is low. This situation is

caused due to a lack of willingness of teacher to implement it.

2. Learning is not meaningful, means that the students can’t related a

material into daily life

3. Less precisely learning approaches that used by teacher to deliver teaching

materials.

4. The students have difficulty in problem solving mathematical because the

understanding concept of the material is still lack.

5. The students have problems in learning the cylinder on sub topic which are

already entered on a higher level, namely its application in daily life.

1.3 Limitation Problem

Making clearly and have mentioned identifying problem hence in this

research is limited about the difference of students problem solving ability

between Contextual Teaching and Learning (CTL) and direct instruction (DI) in

(17)

CHAPTER V

CONCLUSION AND SUGGESTIONS

5.1Conclusion

From the result of research that has been done, it can be conclude that

as follows:

1. The students’ problem solving ability that taught by Contextual Teaching

and Learning (CTL) is better than taught by Direct Instruction (DI) in IX

grade at SMP Negeri 1 Medan Academic Year 2012/2013. It can shown

from post test data is the average is CTL class is 81.54 and DI class is 68.09.

And after calculation use t – test we gotten tcalculate 3.177 and t table 1.684.

2. From the observation by the observer, it can be concluded that the learning CTL approach is better than the learning DI when viewed from the students’ activity. Students were taught through learning model of CTL is more

flexible and the student active by discussion. Students are more active in

doing the questions in student sheet activity. Then, by randomly the students

presenting the result discussion in front of class. Contrast to the student who

were taught through learning model of DI was occur more emphasize in

listening activity to the teacher explanation in front of class.

3. Based on the teachers’ observation that observed it can be concluding that

the teacher who implement the learning CTL approach more attractive

rather than who implement the learning model of DI.

4. The kinds of mistake that student made after being taught using contextual

teaching and learning approach and direct instruction are: wrote not

complete information from the problem, wrote wrong formula of surface

area and volume of cylinder, wrote not complete strategy to solve the

problem, errors in calculation and algebra operation.The kinds of mistake

that student made after being taught using direct instruction are same with

(20)

47

contextual teaching and learning, but they did not make re-evaluation

correctly.

5.2Suggestion

Based on research result, then the suggestions that can be given by writer are:

1. For mathematic teacher, learning taught Contextual Teaching and Learning

(CTL) can be used as alternative learning approach because it can be increase

problem solving skills of student.

2. For mathematics teacher given problem related in daily life then students

should be solve using mathematics problem solving steps.

3. For the next researcher, to make deeper analysis about the mistakes that
