CHAPTER I
INTRODUCTION

1.1

Background
Education is a fundamental human right and essential for the exercise of

all other human rights (UNESCO, 2014). Through education, a wide variety of
knowledge can be transferred to achieve quality and useful life. The best quality
of education will develop knowledge, intelligence, skill, creativity, ability in
solving problems and controls an emotional, attitude, and character. A central
point of education is teaching people to think, then able to solve problems that
faced.
According to UNESCO in World Data on Education (2010), “Although
student outcomes have been improving, Indonesian student rank still low in
international standardized test. The results for Indonesia showed that about 54%
of graduates of ninth grade had not achieved a level of basic competency”. The
government has made a lot of effort to increase education qualities in Indonesia
through the development of curriculum, education facility and infrastructure, also
the quantity and the quality of educators in order to prepare human resources
being independent, critical thought, and qualified. Wiyarsi and Partana (2009)
justified by stating the three main issues that focus in education renewal, they are
the renewal of a curriculum, increasing the learning quality and effectiveness
learning methods. The present of professional teacher in schools will increase the
quality of education in Indonesia because teacher has the main role in learning
process. Teachers through their teaching devise a way to make their students
develop positive attitudes towards science and science related disciplines.
Chemistry is one of a branch of knowledge which has a great influence
on the development of science and technology. Chemistry in high school requires
special acquisition, in order to get a better result, (Wijayati et.al, 2008), but the
fact chemistry in school does not generate satisfactory outcome yet. Generally,
chemistry learning has a purpose to study fact and arrange the theory that can
explain it. Thus, presentation of chemistry material in the process of learning need

2

to be made with attractive and excited so that students understand the concept
independently. Learning chemistry in school is less precise if only pay attention
on final result (learning outcomes) without considering the process that takes
place in every learning process. It happens due to the lack of variation of teaching
models that are used by teachers in high school makes the role of students in
learning process is still passive, most of learning is still dominated by the teacher
(teacher-centered), which make the learning process very monotonous and boring.
According to Silitonga and Situmorang (2011), educational experience
was often faced by chemistry teachers in high school, most students assume that
chemistry as difficult subjects, that’s why they have felt less able to learn it and
scary for them. As result of hard feel the chemistry become less attractive to most
of students, that is the cause low in learning outcomes. In fact, that usually occurs
in school, teachers tend to teach chemistry by direct instructional, asking student
to read learning material, and remembering chemistry concepts. This condition
causes the chemistry learning will not interest and dislike by student then it can be
concluded their learning outcome become low.
Colloidal system is one of an interesting topic in chemistry which most of
materials are concepts that needed to be understood. Colloidal system is in around
us, so by using scientific approach to the environment, student can get deep
understanding. In colloidal system topic will be learned the kinds of colloid,
properties of colloid, differences of suspension, colloid, and real solution,
application of colloid in daily life, and also how to make colloid. Generally,
colloidal system is abstract and has many concepts, so must be applied with varied
example in daily life.
Based on preliminary observations conducted in SMA Negeri 15 Medan,
showed learning outcomes of students in chemistry is still low. The percentage
of students who get value higher than KKM about 72 is only 30%. The same
result also got from observation during the researcher running the PPL
(Experience Field Program) showed that student’s achievement in chemistry topic
still lower than KKM (75). This condition shows they get chemistry outcome did
not satisfactory yet.

3

In order to increase student’s outcomes and get interesting in chemistry,
students are demanded really understand and active during teaching and learning
process. This condition can be made by teachers. Using a suitable learning model,
student can be directed to be active during lessons. Learning model is a ways that
helps and supports teacher and student in teaching-learning. The present of
learning model in class is useful because it can change the class conditions
become interesting and fun for both teachers and students. In this research, the
researcher develop strategy in learning by integrate two leaning model they are
Problem Based Learning model with Cooperative Learning type Teams Games
Tournament.
Problem Based Learning (PBL) is an instructional method where relevant
problems are introduced at the beginning of learning to be solved by collaboration
(interaction) with their group to be done to build an understanding to each
member. PBL is used to provide the context and motivation for the learning that
follows. It is always active and encourages the practice of information –
gathering, reasoning and problem-solving skills, interpersonal and team working
skills, as well as the acquisition of content knowledge, in the process of working
out the problem in collaborative groups. The research in using PBL has been done
by Khairatun (2014), showed there was a difference in student learning outcomes
using model PBL in experimental class (81,24%) better than control class taught
using lecturer method (60,72%) furthermore, Sri Rahmania (2014) examined the
influence of PBL using molymod made of plasticine towards improving senior
high school student's achievement in the hydrocarbon topic, from the results of
this research showed improvement in student achievement by 82% in the
experimental class.
Teams Games Tournament (TGT) is one type of cooperative learning
which emphasizes the cooperation between members of the group to achieve the
learning objectives. The interesting thing from the TGT and which distinguishes it
from other types of cooperative learning is the tournament. In the tournament, the
same academic ability of students who will be competing to get the highest score
in the tournament table. Therefore, every student has the same opportunity to be

4

the best in the tournament table. This will certainly motivate the students to learn
that also affect student achievement. (Nuril, 2009). Isjoni (2011) argues that TGT
is one type of cooperative learning that puts students in groups study consisting of
5 to 6 students who have ability, gender, and ethnicity or a different race. The
teacher presents material, and students work in their groups. The research using
TGT has been done by Wiwit et.al (2012) concluded there was significant effect
of media use animation in the application of cooperative learning model TGT to
chemistry student learning outcomes. In addition, Luluk Fajri et.al (2012) in their
research to improve process and learning outcomes of chemistry in colloidal
system topic through cooperative learning type of TGT give positive result.
Cooperative learning and PBL are common methodologies used in
response to challenges posed by today’s educational outcomes. Colloidal system
will be suitable taught by PBL integrated with TGT according to each advantage
of models. In TGT model, students work together in a small group to accomplish
a shared learning goal and to maximize learning and this condition will develop
their creativity and being active in class (Helmi et.al. 2008), and in PBL, besides
promoting the construction of knowledge, it also contributes to the development
of skills and attitudes deemed important for learning and practice chemistry.
Based on research conducted by Sri Handayani Siregar (2014) obtained the result
of application integrated model of PBL and Guided Inquiry and with computer
media and Direct Instruction can improve learning outcomes and different
compared to direct significant interaction indicated by significant value 0,036.
Based on the discussion above, the researcher would like to investigate the
case of “Implementing Problem Based Learning Integrated with Cooperative
Learning Teams Games Tournament in Improving Students’ Achievement in
Teaching Colloidal System”.

1.2

Identification of Problem
Based on the backgrounds that have been presented above, some

problems are identified as follows: 1) Whether chemistry teachers do not
implement learning methods beside conventional method? 2) Do students

5

consider that chemistry is less attractive and difficult to understand? 3) Is the
learning process through problem based learning integrated with cooperative
learning teams games tournament can be categorized as an innovation of learning
process through direct instruction model for teaching chemistry? 4) Lack of
variation of teaching models makes it difficult for student to study.

1.3

The Scope of Problem
Problems that can be researched based on the background above too

large. In order to make directive study in this research, then some things that
identified as the scope of problems as follows:
1. This study is limited to find out the effect using Problem Based Learning
Model integrated with Cooperative Learning Teams Games Tournament in
improving student’s achievement in teaching Colloidal System.
2. The student’s achievement would be obtained through evaluation test
(pretest and posttest).

1.4

The Problem
The problems can be stated as follows:
1. Is the student’s achievement taught by Problem Based Learning Model
integrated with Cooperative Learning Teams Games Tournament higher
than taught by Problem Based Learning Model in teaching Colloidal
System?
2. How many percents are increasing of student achievement taught by
Problem Based Learning Model integrated with Cooperative Learning
Teams Games Tournament?

1.5

Research Objective
The objectives of this research are to look for,
1. Significant difference between student’s achievements taught by Problem
Based Learning Model integrated with Cooperative Learning Teams

6

Games Tournament and Problem Based Learning in teaching Colloidal
System.
2. Increase percentage of student’s achievement taught by Problem Based
Learning Model integrated with Cooperative Learning Teams Games
Tournament.

1.6

Research Benefit
This research is expected to provide benefits, especially for chemistry

teachers, students and also for the other researchers concerning with learning
through Problem Based Learning Model integrated with Cooperative Learning
Teams Games Tournament to improve student’s

achievement in Colloidal

System. The expected benefits of this research are generally described as follows:
1. Getting learning model that suitable and effective on teaching of concept
in chemistry to increase students’ achievement.
2. As input for chemistry teacher to make chemistry subject become
interesting and active learning thus increase students’ achievement.
3. Improving student motivation to learn and understand about colloidal
system through attractive learning model.
4. To provide inputs for next researchers who want to do similar research.

1.7

Operational Definition
To avoid confusion, then some of the terms in this study need to be

defined like as,
1. Problem Based Learning (PBL) is an instructional method where relevant
problems are introduced at the beginning of teaching and used to provide
context and motivation for learning later. It is always active and usually
(but not necessarily) collaborative or cooperative using above definitions,
(Michael, 2004).
2. Cooperative learning; Teams Games Tournament (TGT) is a model of
learning by forming small groups in class consist of 3-5 students who
heterogeneous in terms of academic, gender, race or ethnicity. TGT

7

cooperative learning consists of five main components, namely: a
presentation in class, team (group), games, tournament, and team
recognition (awards groups) (van Wyk, 2011).
3. Student’s achievement is learning outcome which achieved by student
after he makes change in learning. Learning outcomes are used as a
measure of success in learning, usually from final test. In the Webster’s
New International Dictionary reveals about the achievements are:
“Achievement test is a standardized test for measuring skill or
knowledge by person in one more lines of work a study” (Webster’s New
International Dictionary in Haryanto, 2010).
4. Colloids (Greek, kolia means glue) are dispersion systems which consist
of tiny particles of one substance called dispersed phase in another phase
called dispersing medium (Sudarmo, 2013).

58

CHAPTER V
CONCLUSION AND SUGGESTION

5.1

Conclusion
Base on the research that has been conducted, it can be concluded as follow:

1. The student’s achievement that taught by problem based learning model integrated
with cooperative learning teams games tournament is significant higher than the
student’s achievement that taught by problem based learning model in teaching
colloidal system.
2. There are significant differences of students’ achievement that taught by problem
based learning model integrated with cooperative learning teams games tournament
compare to problem based learning model. The improvement percentage of students’
achievement is 23%.

5.2

Suggestion
From the result of the research, there are some suggestion must be raised:

1. For chemistry teacher, problem based learning model integrated with cooperative
learning teams games tournament could be performed in the learning activities
because these model can improve students’ achievement in chemistry, especially in
colloidal system.
2. For chemistry teacher could be develop the integration of problem based learning
model with another suitable learning model to improve students’ achievement and
activeness in chemistry subject matter.
3. For researcher who wants to do same research, problem based learning model
integrated with cooperative learning teams games tournament is expected to be more
careful in set time for each stage of learning and can create activities that do not take
much time, because this model requires a lot of time.
