CHAPTER 1
INTRODUCTION
1.1. Background
Physics study up to now is still become a lesson which difficult for most
students to obtain good learning achievement in class. Results of data obtained
during Field Training Program, show that the average value of X grade for
physics class is often the lowest value compared with other lessons. Data of
preliminary observations in SMA Islam Al-Ulum Terpadu Medan, also show that
students average value is below of passing standard score, even based on the
assessment carried out in school, students must master at least basic competence
in classical and individual type above or equal to 75.
The low of student’s learning achievement is caused by various factors,
one of them is because students are less interested in physics, most students in X
grade claimed that they followed lessons of physics only as an obligation.
Although there are some students who are able to understand formulas in physics,
but it is still difficult for them to implement these formulas in daily life, so they
think that physics is not needed to solve various problems in daily life. It can be
concluded that most students are not motivated in learning physics. Teacher who
teach are usually using conventional model, where students in the compulsory to
understand formulas without explaining to students of physics concepts contained
therein and its relationship with other subject matter taught in classroom. In
addition, use of media in learning is also very minimal, so students become very
limited activity.
Learning as a process of activities to change behavior of students has
many factors that influence it. From many factors that affect it, can be broadly
divided into classification of internal factors (from within) of students and
external factors (from out) of students. Internal factors are factors that exist
within of learner, while external factors are factors that exist outside of learner.
These internal factors are: (i) physical factors, (ii) psychological factors, and (iii)
2
fatigue factor (Slameto, 2002:54). The process of teaching-learning interactions
related to internal factors is more focused on the problem of motivation and
reinforcement. These internal factors actually related to physiological factors and
psychological factors. But with reinforcement problem, hence the review about
these internal factors will be devoted to psychological factors. Thomas F. Staton
describes six kinds of psychological factors: motivation, concentration, reaction,
organization, comprehension and repetition (Sardiman, 2011:39). This research is
focus on psychological factors of intrinsic motivation.
Someone will succeed in learning, if in itself there is a desire to learn.
This is the principle and first law in educational activities and instruction
(Sardiman, 2011:40). Based on preliminary observations by giving questionnaire
of motivation to students at SMA Islam Al-Ulum Terpadu Medan obtained data
that most of them have a level of motivation that can be categorized as less.
Factors that can affect students' low motivation in learning physics are: 1) physics
study is made be an abstract lesson , 2) students are not encouraged to understand
the concepts of physics; 3) lack of use of instructional media; 4) interaction
between students is limited.
Uno (2011: 23) reveals that, indicators of motivation to learn can be
classified as follows: 1) the desire abnd willingness to learn, 2) the encourage and
need feeling in learning, 3) the hopes and ambition of the future; 4 ) the
appreciation in learning, 5) the interest activity in learning; 6) the existence of a
conducive learning environment.
When students do not have motivation to learn physics properly, this will
affect their learning achievement, which can be ascertained that results of their
learning achievement will also be low. The problem now is how to find the
appropriate way to convey the various concepts so that students have a long-term
understanding of physics concept and implement it in their daily live and how a
good and wise teacher able to use variety of learning media?
To overcome all problems above, it is required learning innovation that
uses a contextual approach to learning and teaching. The challenge is indeed for
educators to design new learning environments and curricula that really encourage
3
motivation and independence to equip students with learning and problem-solving
skills and competencies that employers are looking for (Tan, 2003: 99). Learning
with a contextual approach (Contextual Teaching and Learning (CTL) links
between the material being taught and students real-world situations and
encourage students to make connections between knowledge that they have and its
implementation in their daily lives is expected to improve student learning
achievement. There are three models of CTL namely: Direct Instruction (DI),
Cooperative Learning (CL) and Problem Based Instruction (PBI). In this research
the model will be applied to Problem Based Instruction (PBI)
PBI is a learning model that presents problem to students before they
construct their knowledge.
The problem presented is problem which always
experienced by students in their daily live.
Through PBI students trained
construct their own knowledge, develop problem solving skills, accustomed in
using media, and used to enhance interaction among students of students, so
students become independent, more confident and have a great motivation in
learning physics.
Meanwhile, Ibrahim reveals that the PBI, teachers try to
encourage students to have intrinsic motivation (Rusmiyati & Yulianto, 2009:75).
In his book of “How to Use Problem-Based Learning in Classroom”, Delisle
reveals that research and teachers’ experience have demonstrated that active
instructional techniques like PBL can motivate bored students and raise their
understanding and achievement (Delisle, 1937: 5).
Some research relating to the use of Problem Based Instruction method
has already been done, among others; by Festiyed 1, Ermawati 2 (2008), where
their reaearch showed that by using PBI in learning can provide an increase in
activity and student’s learning achivement, this thing can seen from average value
of student learning achivement which have increased from 5.7 in Cycle I to 6.09
in cycle II. There is also an increase in value of the lowest in cycle I was 4, in
cycle II, the lowest value obtained 5. Most student’s scores have increase, initially
they received score of 5 and 6 in cycle I, to 6 and 7 in cycle II. Research
conducted by them is classroom action research using cycle model. They also
4
suggested that experiments of this study is more extensive, so as to ascertain how
far this PBI method can increase activity and student learning outcomes.
Then by CA Hapsoro, H. Susanto (2011), where the results of their study
showed that PBI-assisted learning aids can achieve basic competencies of students
and student learning outcomes, in addition, PBI-assisted learning aids are better
than conventional learning, this indicated by students' cognitive learning
outcomes, with average value of 69.3415 in control class, while 73.5238 in
experimental class. Increased learning outcomes in control class by 45% whereas
in experimental class by 52%. The results of this research were obtained by using
two classes as a grade control and experimental classes. Advice given in their
research is aimed to improve the quality of education especially in learning
activities, among others; teacher should consider PBI-assisted learning aids to be
applied, because the learning method is proven improve basic competencies and
student learning outcomes significantly, and also implementation of PBI learning
takes a long time so that the efficiency of time is necessary for the purpose of
learning can be achieved.
Next by Cecepullah (2011), describes the results of his research, among
others; increasing creative thinking abilities of students based on the average
normalized gain () after PBI model is applied at 0.272 to a low category, and
increased student achievement based on the average normalized gain () after
PBI model is applied at 0.271 with low category. The results of this research were
obtained by using the method of quasi-experimental (Quasi Experiment). Advice
given by him in his research are as follows: (1) setting the table on the PBI model
should be quite comfortable to use a group of five to six people and do not hinder
the mobility of teachers, (2) the number of groups is not too much, (3 ) required
further research concerning the application of the PBI model, so as to obtain more
consistent results.
Research about the implementation of PBI model to improve student
motivation and learning achievement conducted at high school of grade X in
Medan. This research is conducted by considering low motivation of students in
learning physics which ultimately have an impact on learning outcomes of
5
students automatically become low. Method of this research is by using quasi
experiments with one group post-test, pre-test design. This method was chosen to
determine the increase of students’s motivation and learning achievement after
applying PBI model compared to before applying PBI model.
Based on
description above, will be conducted research with
title
"Implementation of Problem Based Instruction (PBI) Model For Increasing
Students’ Intrinsic Motivation and Learning Achievement in Optic
Instruments Topic at SMA Islam Al-Ulum Terpadu Medan Academic Year
2011-2012" expected the results could provide benefits for teachers, especially in
providing an alternative model of learning in classroom, particularly in efforts to
improve motivation and student’s learning achievement.
1.2. Problems Identification

CHAPTER V
CONCLUSIONS AND RECOMMENDATIONS
5.1. Conclusions
Based on data analysis and discussion of research results, obtained
general conclusion that application of Problem Based Instruction learning model
in optic instruments topic has a low criterion in improve students intrinsic
motivation and have sufficient criteria to improve students learning achievement
in cognitive, effective and psychomotor domains. Based on research questions
that presented earlier, we can conclude some of the following:
1. Increasing of students' intrinsic motivation based on average gain
normalized () after implement Problem Based Instruction Learning
model is equal to 0.362 in a medium category.
2. Increasing of students’ learning achievement based on average
normalized gain
() after implement Problem-Based Instruction
learning model is 0.556 of cognitive domain, 0.600 of affective domain
including into medium category and 0.722 of psychomotor domain
including into high category.
5.2. Recommendations
This research is still far from perfect research. Based on the research
results that have conducted, researcher gives the following recommendations:
1. Table and seating arrangement of students have to suitable by the
characteristics of learning model that used. Particularly in PBI learning
model, the shape of table should not elongated and comfortable enough
to used by a group of five to six students. In addition, the position of
tables is not impeding mobility of teacher when guiding students groups.
2. The number of groups should not be too much for teachers for more
maximum control of student activity, especially at investigation stage.
3. Further research is needed of implementation Problem Based Instruction
leaning model in improve students’ intrinsic motivation and learning
achievement at the same subject, to obtain more consistent results
research.
4. For researcher who wants to investigate further more about Problem
Based Instruction (PBI) learning model should pay more attention to the
weaknesses of this learning model to obtain better results.

CHAPTER 1
INTRODUCTION
1.1. Background
Physics study up to now is still become a lesson which difficult for most
students to obtain good learning achievement in class. Results of data obtained
during Field Training Program, show that the average value of X grade for
physics class is often the lowest value compared with other lessons. Data of
preliminary observations in SMA Islam Al-Ulum Terpadu Medan, also show that
students average value is below of passing standard score, even based on the
assessment carried out in school, students must master at least basic competence
in classical and individual type above or equal to 75.
The low of student’s learning achievement is caused by various factors,
one of them is because students are less interested in physics, most students in X
grade claimed that they followed lessons of physics only as an obligation.
Although there are some students who are able to understand formulas in physics,
but it is still difficult for them to implement these formulas in daily life, so they
think that physics is not needed to solve various problems in daily life. It can be
concluded that most students are not motivated in learning physics. Teacher who
teach are usually using conventional model, where students in the compulsory to
understand formulas without explaining to students of physics concepts contained
therein and its relationship with other subject matter taught in classroom. In
addition, use of media in learning is also very minimal, so students become very
limited activity.
Learning as a process of activities to change behavior of students has
many factors that influence it. From many factors that affect it, can be broadly
divided into classification of internal factors (from within) of students and
external factors (from out) of students. Internal factors are factors that exist
within of learner, while external factors are factors that exist outside of learner.
These internal factors are: (i) physical factors, (ii) psychological factors, and (iii)
2
fatigue factor (Slameto, 2002:54). The process of teaching-learning interactions
related to internal factors is more focused on the problem of motivation and
reinforcement. These internal factors actually related to physiological factors and
psychological factors. But with reinforcement problem, hence the review about
these internal factors will be devoted to psychological factors. Thomas F. Staton
describes six kinds of psychological factors: motivation, concentration, reaction,
organization, comprehension and repetition (Sardiman, 2011:39). This research is
focus on psychological factors of intrinsic motivation.
Someone will succeed in learning, if in itself there is a desire to learn.
This is the principle and first law in educational activities and instruction
(Sardiman, 2011:40). Based on preliminary observations by giving questionnaire
of motivation to students at SMA Islam Al-Ulum Terpadu Medan obtained data
that most of them have a level of motivation that can be categorized as less.
Factors that can affect students' low motivation in learning physics are: 1) physics
study is made be an abstract lesson , 2) students are not encouraged to understand
the concepts of physics; 3) lack of use of instructional media; 4) interaction
between students is limited.
Uno (2011: 23) reveals that, indicators of motivation to learn can be
classified as follows: 1) the desire abnd willingness to learn, 2) the encourage and
need feeling in learning, 3) the hopes and ambition of the future; 4 ) the
appreciation in learning, 5) the interest activity in learning; 6) the existence of a
conducive learning environment.
When students do not have motivation to learn physics properly, this will
affect their learning achievement, which can be ascertained that results of their
learning achievement will also be low. The problem now is how to find the
appropriate way to convey the various concepts so that students have a long-term
understanding of physics concept and implement it in their daily live and how a
good and wise teacher able to use variety of learning media?
To overcome all problems above, it is required learning innovation that
uses a contextual approach to learning and teaching. The challenge is indeed for
educators to design new learning environments and curricula that really encourage
3
motivation and independence to equip students with learning and problem-solving
skills and competencies that employers are looking for (Tan, 2003: 99). Learning
with a contextual approach (Contextual Teaching and Learning (CTL) links
between the material being taught and students real-world situations and
encourage students to make connections between knowledge that they have and its
implementation in their daily lives is expected to improve student learning
achievement. There are three models of CTL namely: Direct Instruction (DI),
Cooperative Learning (CL) and Problem Based Instruction (PBI). In this research
the model will be applied to Problem Based Instruction (PBI)
PBI is a learning model that presents problem to students before they
construct their knowledge.
The problem presented is problem which always
experienced by students in their daily live.
Through PBI students trained
construct their own knowledge, develop problem solving skills, accustomed in
using media, and used to enhance interaction among students of students, so
students become independent, more confident and have a great motivation in
learning physics.
Meanwhile, Ibrahim reveals that the PBI, teachers try to
encourage students to have intrinsic motivation (Rusmiyati & Yulianto, 2009:75).
In his book of “How to Use Problem-Based Learning in Classroom”, Delisle
reveals that research and teachers’ experience have demonstrated that active
instructional techniques like PBL can motivate bored students and raise their
understanding and achievement (Delisle, 1937: 5).
Some research relating to the use of Problem Based Instruction method
has already been done, among others; by Festiyed 1, Ermawati 2 (2008), where
their reaearch showed that by using PBI in learning can provide an increase in
activity and student’s learning achivement, this thing can seen from average value
of student learning achivement which have increased from 5.7 in Cycle I to 6.09
in cycle II. There is also an increase in value of the lowest in cycle I was 4, in
cycle II, the lowest value obtained 5. Most student’s scores have increase, initially
they received score of 5 and 6 in cycle I, to 6 and 7 in cycle II. Research
conducted by them is classroom action research using cycle model. They also
4
suggested that experiments of this study is more extensive, so as to ascertain how
far this PBI method can increase activity and student learning outcomes.
Then by CA Hapsoro, H. Susanto (2011), where the results of their study
showed that PBI-assisted learning aids can achieve basic competencies of students
and student learning outcomes, in addition, PBI-assisted learning aids are better
than conventional learning, this indicated by students' cognitive learning
outcomes, with average value of 69.3415 in control class, while 73.5238 in
experimental class. Increased learning outcomes in control class by 45% whereas
in experimental class by 52%. The results of this research were obtained by using
two classes as a grade control and experimental classes. Advice given in their
research is aimed to improve the quality of education especially in learning
activities, among others; teacher should consider PBI-assisted learning aids to be
applied, because the learning method is proven improve basic competencies and
student learning outcomes significantly, and also implementation of PBI learning
takes a long time so that the efficiency of time is necessary for the purpose of
learning can be achieved.
Next by Cecepullah (2011), describes the results of his research, among
others; increasing creative thinking abilities of students based on the average
normalized gain () after PBI model is applied at 0.272 to a low category, and
increased student achievement based on the average normalized gain () after
PBI model is applied at 0.271 with low category. The results of this research were
obtained by using the method of quasi-experimental (Quasi Experiment). Advice
given by him in his research are as follows: (1) setting the table on the PBI model
should be quite comfortable to use a group of five to six people and do not hinder
the mobility of teachers, (2) the number of groups is not too much, (3 ) required
further research concerning the application of the PBI model, so as to obtain more
consistent results.
Research about the implementation of PBI model to improve student
motivation and learning achievement conducted at high school of grade X in
Medan. This research is conducted by considering low motivation of students in
learning physics which ultimately have an impact on learning outcomes of
5
students automatically become low. Method of this research is by using quasi
experiments with one group post-test, pre-test design. This method was chosen to
determine the increase of students’s motivation and learning achievement after
applying PBI model compared to before applying PBI model.
Based on
description above, will be conducted research with
title
"Implementation of Problem Based Instruction (PBI) Model For Increasing
Students’ Intrinsic Motivation and Learning Achievement in Optic
Instruments Topic at SMA Islam Al-Ulum Terpadu Medan Academic Year
2011-2012" expected the results could provide benefits for teachers, especially in
providing an alternative model of learning in classroom, particularly in efforts to
improve motivation and student’s learning achievement.
1.2. Problems Identification
Based on description of background above, problem can be identified as
follows:
1. Teacher is usually using conventional model.
2. Most students in X grade at SMA Islam Al-Ulum Terpadu Medan have
low intrinsic motivation in learning physics.
3. Average student learning achievement is below of passing standards.
1.3. Problems Limitation

CHAPTER V
CONCLUSIONS AND RECOMMENDATIONS
5.1. Conclusions
Based on data analysis and discussion of research results, obtained
general conclusion that application of Problem Based Instruction learning model
in optic instruments topic has a low criterion in improve students intrinsic
motivation and have sufficient criteria to improve students learning achievement
in cognitive, effective and psychomotor domains. Based on research questions
that presented earlier, we can conclude some of the following:
1. Increasing of students' intrinsic motivation based on average gain
normalized () after implement Problem Based Instruction Learning
model is equal to 0.362 in a medium category.
2. Increasing of students’ learning achievement based on average
normalized gain
() after implement Problem-Based Instruction
learning model is 0.556 of cognitive domain, 0.600 of affective domain
including into medium category and 0.722 of psychomotor domain
including into high category.
5.2. Recommendations
This research is still far from perfect research. Based on the research
results that have conducted, researcher gives the following recommendations:
1. Table and seating arrangement of students have to suitable by the
characteristics of learning model that used. Particularly in PBI learning
model, the shape of table should not elongated and comfortable enough
to used by a group of five to six students. In addition, the position of
tables is not impeding mobility of teacher when guiding students groups.
2. The number of groups should not be too much for teachers for more
maximum control of student activity, especially at investigation stage.
3. Further research is needed of implementation Problem Based Instruction
leaning model in improve students’ intrinsic motivation and learning
achievement at the same subject, to obtain more consistent results
research.
4. For researcher who wants to investigate further more about Problem
Based Instruction (PBI) learning model should pay more attention to the
weaknesses of this learning model to obtain better results.
