learning. Field test activity was conducted to the
students of Junior High School 18 Palembang. Field
test activity was also done to see the activity and
student learning outcomes.
3 RESULT AND DISCUSSION
The result of this study was valid, practical, and
effective PBL based Students’ Worksheets to be
used in learning Social Science in Junior High
School. This research used Hannafin and Peck
development model which included three phases of
activities that are analysis, design, development, and
also implementation phase which is accompanied by
evaluation and revision process. From the results of
researchers’ observations and interviews with Social
Science teachers on the course of Social Science
learning in the first grade of Junior High School
students were identified the interest and participation
of student learning and mastery of Social Science
concepts which were indicated low by learning
outcomes and learning motivation. In the learning
process, teachers and students were used teaching
materials in the form of textbook that have not been
able to facilitate, trigger and encourage students to
be sensitive to understand, assess, criticize and find
solutions to social problems of that occur in society.
This problem will be solved by developing Problem-
Based Student Worksheets.
During the design phase, the initial step is
curriculum analysis which aims to determine which
material requires Students’ Worksheet, arranging the
Students’ Worksheet needs map to find out the
number and sequences of Students’ Worksheet and
determine the Students’ Worksheet title based on the
Basic Competencies of the curriculum. After
analyzing, drawing up a map of needs and
determining the Students’ Worksheet title was the
next step in this design is to create Students’
Worksheet with title structure, learning instructions,
basic competencies, indicators, learning objectives,
material descriptions, the worksheet supporting
information, assignments and work steps that
systematically include problem identification
activities, assign temporary answers (hypotheses),
collect or search for relevant data to support the
hypothesis, test the truth of the answers and draw
conclusions as the implementation point of problem
based learning.
Students’ Worksheet products that have been
completed in the design phase are then developed
into a teaching material product in the form of PBL
based Students’ Worksheet. During the development
process, an evaluation and revision of the
shortcomings of the produced Students’ Worksheet
was carried out. Products that have been developed
before which were implemented in the field are
evaluated first. The evaluation used was the Tessmer
evaluation model which includes stages of self-
evaluation, review experts, one to one evaluation,
small group evaluation and field tests. In the stage of
self-evaluation, developed Students’ Worksheets
based on Problem Based Learning were evaluated by
the research team themselves. Evaluation was
focused on design, layout, and content. Some
improvements made after this stage of self-
evaluation are; black and white Students’
Worksheets were printed in color to make them
more attractive; front cover image which was
originally a picture of a polluted river was replaced
with urban images; in the material description of the
ASEAN countries competency was added a picture
of the countries symbol next to the flag images.
In the experimental stage of review, the
Students’ Worksheet based on problem based
learning product had been revised through self-
evaluation stage validated by expert and teacher
practitioners who have experience in social science
learning. Validation focused on design, layout and
content. The result of the improvement of product
will be called prototype 1.
In the expert review stage, Problem-Based
Students’ Worksheet products which have been
revised through the self-evaluation stage are
validated by expert and teacher practitioners who
have experienced in teaching Social Science.
Validation focused on the design, layout, and
content. The product improvement result after
getting input from the validator will be prototype 1.
The evaluation of design expert validator and
practitioner teacher on the worksheets was assessed
based on three aspects of assessment; first, content
feasibility, which consisted of material suitability
with Competency Standards and Basic
Competencies, material accuracy, material support,
and material updates, second, presentation feasibility
which consists of four indicators; presentation
techniques, supporting presentation, learning
presentation and completeness of presentation, third,
language feasibility consisting of six indicators;
logical, communicative, dialog and interactive,
conformity with the level of student development,
clarity in the flow of thought and the use of term
symbols.
The average score of two validators on content
feasibility is 4.30, which means that the developed
PBL based Students’ Worksheets is very feasible to
