ABSTRACT
This thesis purposes the implementation of Contextual Teaching and
Learning using concept map on the teaching acid base topic. The objectives of
research are to determine the difference of student’s outcomes in acid base topic
by CTL using concept map compared to conventional model and to determine the
influence the student’s outcome of CTL using concept map in learning acid base
topic. The population of this research were all of students in grade XI, 2nd
semester and academic year 2015/2016 in Indonesia. The samples are 2 classes
from student in SMA N 11 Medan by purposive random sampling method. The
experimental class is learned by CTL using concept map and control class is
learned by conventional model. The instruments are using multiple choice test to
see the student’s outcome. The instrument of research is standardized by expert
validator and empiric validity. Data analysis is using manual calculation. The
result of test is standardized and there are 21 items valid with reliability is
0.90474. The result data shows that the student’s outcome taught by CTL using
concept map give higher significant difference than taught by conventional model.
It can be seen from the average of gain and also proved with z-test, the normalized
gain in experimental class (0.6388±0.1495) and control class (0.1958±0.1269).
The statement support the research data result of hypothesis test is zcount = 14.2995
and ztable = 1.645. The calculation shows that Ha is received or H0 is rejected. Ha is
student’s outcomes through Contextual Teaching and Learning used concept map
media is higher than using conventional method in acid base topic, and H0 is
student’s outcomes through Contextual Teaching and Learning used concept map
media is less than using conventional method in acid base topic.
Keywords : CTL, Concept Map, Conventional, Student’s Outcome, Acid Base

CHAPTER I
INTRODUCTION
1.1
The Background
The era of globalization is an era of competition that demands to education
especially in Indonesia be able to produce a cadre of qualified nation, intelligent,
independent, critical, creative, and innovative. This of course meant that the
nation's future can face all the problems of the times and be able to compete with
the world. Therefore, education should be adapted to the culture in Indonesia so
the education is embedded within the community that students can make them
recognize, appreciate, and utilize existing resources as well as possible. It has
been realized that the quality of a nation is determined by the quality of human
resources available. Therefore, education is the most important aspect in
improving the quality of human resources in Indonesia.
The effort made by the government was not a little to improve the quality
of education in Indonesia. One of them with changes the curriculum’s structure
refers to the content standards and competency standards. In the old curriculum of
learning tend in one direction from teacher to students (teacher centered), while
students are less active role in learning. In this case students are required to play
an active role in learning (student centered), while the teacher acts as a facilitator,
motivator and evaluator. Thus, students are expected to be active, creative,
critical, intelligent, and independent in search of information to build knowledge.
Students are expected not only memorized and understanding of concepts and
principles, knowing the facts, but it is expected that students can apply in daily
life.
Problems often arose in the study was from the students themselves as a
student. The absence of its own preparation of students before receiving the
learning and understanding of the concepts are still less its cause the student only
receives the information presented by teacher. This will cause the students quickly
forget the lessons and thinking activity of students and seeking truth of
1
2
information that presented is very less. Activity of student as critical thinkers has
not done well and students are less sensitive to incoming information.
Lack of preparation in students will make students less creative in dealing
problems. Creative attitude of students who are lacking can be seen from how the
students seek information on the subject those materials. This causes the students
tend not produce a lot of ideas to solve the problem because lack of learning
resources obtained by students.
Competence of student’s outcome is very important to be considered by
educators to face an era full of challenges. Students are required to always active
in dealing the problems in the era of globalization that full of competition and the
higher complexity of the problems in all aspects of life. The development of
creativity abandoned in formal education, but more meaningful for the
development of children's potential and for the advancement of knowledge, arts
and culture (Dewey,John, 2006)
Chemistry as science subjects have characteristics based on practice and
experimentation. Therefore, students are required not only to feel understood the
material and concepts but can be practiced by answering questions, conduct
experiments and solve problems in daily life. This of course requires students to
be sensitive to the existing problems by actively searching for a lot of resources to
get a solution or problem-solving ideas from various perspectives.
Chemistry teaching methodology in schools that have implemented the
educational unit level is considered to be quite varied in addition, with the various
facilities such as a chemical laboratory and an adequate library as a source of
student learning allows students to learn by looking for as much information. This
course will help students to be more active in dealing the problems that exist.
With active the students are expected to solve problems with more open attitude,
systematic, logical, and produce a lot of ideas. The process of thinking like this
will make students more independent learning with developing them own
knowledge ( Arends, 2009 ).
3
Based on discussions with teachers of chemistry student issues still tend to
solve problems using methods delivered by teachers, students often forget the
subject matter, and the lack of preparation of the students before the lesson begins.
This cause the students are less prepare in solving problems (especially chemical
matters). Students are also less sensitive to their environment issues related to
chemistry. For example, from waking up to going to bed back students certainly
faced with chemicals, such as soap, toothpaste, detergent, food and fruits,
cosmetics, fuel, clothing, and so forth. Surely this is a problem that must be
followed and it was time held innovation in teaching chemistry to boost traffic
critical and creative thinking.
To dealing these problems one of which is the teaching methodology
presented by the teacher that the teacher should know the right step in the present
study include the approaches, methods, strategies, media and student learning
resources. Among them by using an instructional activities that provide
opportunities for students to think freely, directing students seek information from
various sources, guiding students to be sensitive to problems, critical in solving
the problem in various ways and from different angles ( Hamalik, 2008 ).
One approach to learning that is considered appropriate in learning
problem through the CTL is a learning system based on the philosophy a learner
will be able to absorb the subject matter if they are able to absorb the meaning of
the lesson. CTL on learning approach will help students in making connections
between the subject matter with real life, so that students will get the meaning of
what they learned as Johnson said that contextual teaching and learning enables
students to connect the content of academic subject with the immediate context of
their daily lives to discover meaning. It enlarges their personal context
furthermore, by providing students with fresh experiences that stimulate the brain
to make new connection and consequently, to discover new meaning.
CTL using concept map are expected to help students in improving
learning outcome of students. The Problem that is raised will challenge students to
think critically in solving these problems. Students are also challenged to be
4
creative in finding resources, put forward good ideas, and solutions solving of
various viewpoints.
CTL is a system that stimulates the brain to arrange the patterns from the
meaning. CTL system learning that suitable with brain that produce meaning in
relating academic charge with context from student’s daily life. Through by CTL
using concept map, students are expected to be trained to improve learning
outcome. Concept in teaching-learning process also determine the influence how
the protege easy to catch the material topic. So one way is concept map. Concept
map give the keyword of topic, save keyword is easy to solve the problem.
Keyword easy to remember than all the material. ( Johnson, 2009 ).
Based on the above reasons, the researcher is interested to conduct
research under the title “The Implementation of Contextual Teaching and
Learning Using Concept Map on The Teaching Acid Base Topic”.
1.2
Problem Identification
Based on the background above, problem identification of this research as
follow:
1. Nothing self-preparation of students before receive the learning and
understanding of the concepts are still less its cause the student only receives
the information presented by teacher.
2. The lack of application the instructional media to support the classroom
learning process.
3. Students assume that the chemistry is an abstrack lesson because only taught
theoretically.
4. The lack of student’s participation in learning process.
5. Learning models that are less varied as required by the subject matter.
1.3
Research Scope
Based on the scope of problems identification above, this research will be
limited as follows:
5
1. Arranging the teaching materials in the form of syllabus and lesson plan
systematically.
2. Preparing the discussion material that taught by CTL and concept map.
3. Instrument test will be reviewed and revised by the lecturer from the
Department of Chemistry Education.
1.4
Problem Formulation
The problem formulations of this research are:
1. Is there difference of student’s outcomes in acid base topic by CTL using
concept map compared to conventional model?
2. Is there influence the student’s outcome of CTL using concept map on
student’s outcomes in learning acid base topic?
1.5
Research Objective
The objectives of this research are:
1. To know the difference of student’s outcomes in acid base topic by CTL using
concept map compared to conventional model.
2. To know the influence the student’s outcome of CTL using concept map in
learning acid base topic.
1.6
Research Benefit
The benefits of this research are:
1. Provide the broad outlines of innovative learning to the science teachers,
especially in using the CTL with concept map in learning process.
2. Provide the learning reference that can be used in high school on the material
acid base.
3. Help students to learn through active learning to foster their interest and
motivation to learn.
4. Provide input to the next researcher to conduct the same experiment later.
6
1.7
Operational Definition
The operational definitions in this research consist of:
1. Contextual Teaching and Learning
Contextual teaching and learning is a conception of teaching and learning that
helps teachers relate subject matter content to real world situations; and motivates
students to make connections between knowledge and its applications to their
lives as family members, citizens, and workers; and engage in the hard work that
learning requires (Hudson, 2000).
2. Concept Map
Concept Map is part of a concept or idea as a basic material that aims to build
students' knowledge in a systematic study (Istarani, 2011).
3. Learning Outcomes
Student learning outcomes measured on cognitive realm by giving pretest as
initial knowledge and posttest as end knowledge after treatment.
4.
Media
Media education in general is a teaching and learning tool. Multimedia application
design offers new insights into the learning process of the designer and forces him
or her to represent information and knowledge in a new and innovative way
(Agnew, Kellerman & Meyer, 1996).
5.
Conventional Model
According Djamarah (1996), conventional teaching methods are traditional
learning methods or collectively, the lecture method, because since the first of this
method has been used as a means of oral communication between teachers and
students in the learning process and learning. In the conventional method of
teaching history is marked with lectures, accompanied by an explanation as well
as the division of tasks and exercises. Learning the conventional method, learners
are more listened to the teacher in front of class and perform tasks if teachers
provide practice questions to students. Are often used on conventional teaching
methods include lectures, question and answer method, discussion method, the
assignment method.
CHAPTER V
CONCLUSION AND SUGGESTION
5.1
Conclusion
Based on the above result, can conclude that:
1. Student’s outcome taught by CTL using concept map is significant
better than student’s outcome taught by conventional with manual
calculation, Z
calculation
is 14.2995, it means z
calculation
>z
table,
(1.645),
Ha is accepted and H0 is rejected.
2. The influence student’s outcome of CTL using concept map is better
than conventional, because the percentage student’s outcome in
experimental class is higher than control class (63.88 % > 19.58 %), it
means there is have increasing.
5.2
Suggestion
Form the result of the research, there are some suggestion must be raised :
1. Chemistry teaching can use contextual teaching and learning using
concep map on the tesching acid based topic to increase the student’s
outcomes in learning process.
2. Another researcher that want to implement contextual teaching and
learning can make variation with some learning media.

ABSTRACT
This thesis purposes the implementation of Contextual Teaching and
Learning using concept map on the teaching acid base topic. The objectives of
research are to determine the difference of student’s outcomes in acid base topic
by CTL using concept map compared to conventional model and to determine the
influence the student’s outcome of CTL using concept map in learning acid base
topic. The population of this research were all of students in grade XI, 2nd
semester and academic year 2015/2016 in Indonesia. The samples are 2 classes
from student in SMA N 11 Medan by purposive random sampling method. The
experimental class is learned by CTL using concept map and control class is
learned by conventional model. The instruments are using multiple choice test to
see the student’s outcome. The instrument of research is standardized by expert
validator and empiric validity. Data analysis is using manual calculation. The
result of test is standardized and there are 21 items valid with reliability is
0.90474. The result data shows that the student’s outcome taught by CTL using
concept map give higher significant difference than taught by conventional model.
It can be seen from the average of gain and also proved with z-test, the normalized
gain in experimental class (0.6388±0.1495) and control class (0.1958±0.1269).
The statement support the research data result of hypothesis test is zcount = 14.2995
and ztable = 1.645. The calculation shows that Ha is received or H0 is rejected. Ha is
student’s outcomes through Contextual Teaching and Learning used concept map
media is higher than using conventional method in acid base topic, and H0 is
student’s outcomes through Contextual Teaching and Learning used concept map
media is less than using conventional method in acid base topic.
Keywords : CTL, Concept Map, Conventional, Student’s Outcome, Acid Base

CHAPTER I
INTRODUCTION
1.1
The Background
The era of globalization is an era of competition that demands to education
especially in Indonesia be able to produce a cadre of qualified nation, intelligent,
independent, critical, creative, and innovative. This of course meant that the
nation's future can face all the problems of the times and be able to compete with
the world. Therefore, education should be adapted to the culture in Indonesia so
the education is embedded within the community that students can make them
recognize, appreciate, and utilize existing resources as well as possible. It has
been realized that the quality of a nation is determined by the quality of human
resources available. Therefore, education is the most important aspect in
improving the quality of human resources in Indonesia.
The effort made by the government was not a little to improve the quality
of education in Indonesia. One of them with changes the curriculum’s structure
refers to the content standards and competency standards. In the old curriculum of
learning tend in one direction from teacher to students (teacher centered), while
students are less active role in learning. In this case students are required to play
an active role in learning (student centered), while the teacher acts as a facilitator,
motivator and evaluator. Thus, students are expected to be active, creative,
critical, intelligent, and independent in search of information to build knowledge.
Students are expected not only memorized and understanding of concepts and
principles, knowing the facts, but it is expected that students can apply in daily
life.
Problems often arose in the study was from the students themselves as a
student. The absence of its own preparation of students before receiving the
learning and understanding of the concepts are still less its cause the student only
receives the information presented by teacher. This will cause the students quickly
forget the lessons and thinking activity of students and seeking truth of
1
2
information that presented is very less. Activity of student as critical thinkers has
not done well and students are less sensitive to incoming information.
Lack of preparation in students will make students less creative in dealing
problems. Creative attitude of students who are lacking can be seen from how the
students seek information on the subject those materials. This causes the students
tend not produce a lot of ideas to solve the problem because lack of learning
resources obtained by students.
Competence of student’s outcome is very important to be considered by
educators to face an era full of challenges. Students are required to always active
in dealing the problems in the era of globalization that full of competition and the
higher complexity of the problems in all aspects of life. The development of
creativity abandoned in formal education, but more meaningful for the
development of children's potential and for the advancement of knowledge, arts
and culture (Dewey,John, 2006)
Chemistry as science subjects have characteristics based on practice and
experimentation. Therefore, students are required not only to feel understood the
material and concepts but can be practiced by answering questions, conduct
experiments and solve problems in daily life. This of course requires students to
be sensitive to the existing problems by actively searching for a lot of resources to
get a solution or problem-solving ideas from various perspectives.
Chemistry teaching methodology in schools that have implemented the
educational unit level is considered to be quite varied in addition, with the various
facilities such as a chemical laboratory and an adequate library as a source of
student learning allows students to learn by looking for as much information. This
course will help students to be more active in dealing the problems that exist.
With active the students are expected to solve problems with more open attitude,
systematic, logical, and produce a lot of ideas. The process of thinking like this
will make students more independent learning with developing them own
knowledge ( Arends, 2009 ).
3
Based on discussions with teachers of chemistry student issues still tend to
solve problems using methods delivered by teachers, students often forget the
subject matter, and the lack of preparation of the students before the lesson begins.
This cause the students are less prepare in solving problems (especially chemical
matters). Students are also less sensitive to their environment issues related to
chemistry. For example, from waking up to going to bed back students certainly
faced with chemicals, such as soap, toothpaste, detergent, food and fruits,
cosmetics, fuel, clothing, and so forth. Surely this is a problem that must be
followed and it was time held innovation in teaching chemistry to boost traffic
critical and creative thinking.
To dealing these problems one of which is the teaching methodology
presented by the teacher that the teacher should know the right step in the present
study include the approaches, methods, strategies, media and student learning
resources. Among them by using an instructional activities that provide
opportunities for students to think freely, directing students seek information from
various sources, guiding students to be sensitive to problems, critical in solving
the problem in various ways and from different angles ( Hamalik, 2008 ).
One approach to learning that is considered appropriate in learning
problem through the CTL is a learning system based on the philosophy a learner
will be able to absorb the subject matter if they are able to absorb the meaning of
the lesson. CTL on learning approach will help students in making connections
between the subject matter with real life, so that students will get the meaning of
what they learned as Johnson said that contextual teaching and learning enables
students to connect the content of academic subject with the immediate context of
their daily lives to discover meaning. It enlarges their personal context
furthermore, by providing students with fresh experiences that stimulate the brain
to make new connection and consequently, to discover new meaning.
CTL using concept map are expected to help students in improving
learning outcome of students. The Problem that is raised will challenge students to
think critically in solving these problems. Students are also challenged to be
4
creative in finding resources, put forward good ideas, and solutions solving of
various viewpoints.
CTL is a system that stimulates the brain to arrange the patterns from the
meaning. CTL system learning that suitable with brain that produce meaning in
relating academic charge with context from student’s daily life. Through by CTL
using concept map, students are expected to be trained to improve learning
outcome. Concept in teaching-learning process also determine the influence how
the protege easy to catch the material topic. So one way is concept map. Concept
map give the keyword of topic, save keyword is easy to solve the problem.
Keyword easy to remember than all the material. ( Johnson, 2009 ).
Based on the above reasons, the researcher is interested to conduct
research under the title “The Implementation of Contextual Teaching and
Learning Using Concept Map on The Teaching Acid Base Topic”.
1.2
Problem Identification
Based on the background above, problem identification of this research as
follow:
1. Nothing self-preparation of students before receive the learning and
understanding of the concepts are still less its cause the student only receives
the information presented by teacher.
2. The lack of application the instructional media to support the classroom
learning process.
3. Students assume that the chemistry is an abstrack lesson because only taught
theoretically.
4. The lack of student’s participation in learning process.
5. Learning models that are less varied as required by the subject matter.
1.3
Research Scope
Based on the scope of problems identification above, this research will be
limited as follows:
5
1. Arranging the teaching materials in the form of syllabus and lesson plan
systematically.
2. Preparing the discussion material that taught by CTL and concept map.
3. Instrument test will be reviewed and revised by the lecturer from the
Department of Chemistry Education.
1.4
Problem Formulation
The problem formulations of this research are:
1. Is there difference of student’s outcomes in acid base topic by CTL using
concept map compared to conventional model?
2. Is there influence the student’s outcome of CTL using concept map on
student’s outcomes in learning acid base topic?
1.5
Research Objective
The objectives of this research are:
1. To know the difference of student’s outcomes in acid base topic by CTL using
concept map compared to conventional model.
2. To know the influence the student’s outcome of CTL using concept map in
learning acid base topic.
1.6
Research Benefit
The benefits of this research are:
1. Provide the broad outlines of innovative learning to the science teachers,
especially in using the CTL with concept map in learning process.
2. Provide the learning reference that can be used in high school on the material
acid base.
3. Help students to learn through active learning to foster their interest and
motivation to learn.
4. Provide input to the next researcher to conduct the same experiment later.
6
1.7
Operational Definition
The operational definitions in this research consist of:
1. Contextual Teaching and Learning
Contextual teaching and learning is a conception of teaching and learning that
helps teachers relate subject matter content to real world situations; and motivates
students to make connections between knowledge and its applications to their
lives as family members, citizens, and workers; and engage in the hard work that
learning requires (Hudson, 2000).
2. Concept Map
Concept Map is part of a concept or idea as a basic material that aims to build
students' knowledge in a systematic study (Istarani, 2011).
3. Learning Outcomes
Student learning outcomes measured on cognitive realm by giving pretest as
initial knowledge and posttest as end knowledge after treatment.
4.
Media
Media education in general is a teaching and learning tool. Multimedia application
design offers new insights into the learning process of the designer and forces him
or her to represent information and knowledge in a new and innovative way
(Agnew, Kellerman & Meyer, 1996).
5.
Conventional Model
According Djamarah (1996), conventional teaching methods are traditional
learning methods or collectively, the lecture method, because since the first of this
method has been used as a means of oral communication between teachers and
students in the learning process and learning. In the conventional method of
teaching history is marked with lectures, accompanied by an explanation as well
as the division of tasks and exercises. Learning the conventional method, learners
are more listened to the teacher in front of class and perform tasks if teachers
provide practice questions to students. Are often used on conventional teaching
methods include lectures, question and answer method, discussion method, the
assignment method.
CHAPTER V
CONCLUSION AND SUGGESTION
5.1
Conclusion
Based on the above result, can conclude that:
1. Student’s outcome taught by CTL using concept map is significant
better than student’s outcome taught by conventional with manual
calculation, Z
calculation
is 14.2995, it means z
calculation
>z
table,
(1.645),
Ha is accepted and H0 is rejected.
2. The influence student’s outcome of CTL using concept map is better
than conventional, because the percentage student’s outcome in
experimental class is higher than control class (63.88 % > 19.58 %), it
means there is have increasing.
5.2
Suggestion
Form the result of the research, there are some suggestion must be raised :
1. Chemistry teaching can use contextual teaching and learning using
concep map on the tesching acid based topic to increase the student’s
outcomes in learning process.
2. Another researcher that want to implement contextual teaching and
learning can make variation with some learning media.
