Syntax Construct Validity Of Project Based Learning Ofglobal Warming Material
Abstract: The aim of this
research is to test construct validity in the syntax development model of
Project Based Learning (PjBL) based on Physics learning in the Global Warming
material at Senior High School. This is a quantitative research used Research
and Development (R & D) model. The model development that was used in this
research is Borg model and Gall, that is descriptively model, which is showed
the steps that should be followed to create product, in this case in form of
syntax of PjBL learning model based scientific approach. The first step of this
research was collecting data information related to the need analysis in the
field related with implementation of Curriculum 2013 in the Physics learning.
As it’s established in curriculum that through learning process in each subject
it is hoped that can direct students to implement the concepts which they are
got to solve the problems or natural phenomenon through scientific approach. In
the Physics learning at Senior High School, PjBL become a one learning model
which applicative to the citizen dynamic, for those it is needed to develop a
syntax model of PjBL based on scientific approach that appropriate in learning.
Data collection is done by documentation technique, interview, questionnaire,
and test. The data collection is in form of qualitative and quantitative data.
The datum were considered valid through repetition process (iteration) and the
data that often appear the being analyse qualitatively through Miles and
Huberman interactive model, that is through data reduction, data display and
drawing conclusion in the same time and after data collection process. Data
analysis technique that is used was descriptive qualitative analysis. The
result of expert validation stated that the product is appropriate to be tested
in the school with some revision. The result shows that the learning syntax
that was designed was appropriate to be tested to students with some revision.
The test was done, to each test project threat to the big group of students’
amount 32 students. Based on the test result which was conducted it is got the
average percentage who achieved passing grade is 84%. So that the product which
is created is effective to be implemented in the Physics learning process at
Senior High School. The result of this research is in form of syntax model of
PjBL in Physics learning in Global Warming material for students of Senior High
School with the characteristics below: (1) Learning syntax that is developed is
suited with scientific learning approach (2) Global Warming material divides in
two projects that is project of The Cause of Global Warming and Reducing Carbon
Track (3) Each project has different time allocation, viewed from the
comprehensiveness the material and the project that is developed. Then, it can
be concluded that the product which is created in this case is in form of
syntax model of PjBL based on scientific approach, lesson plan, and students’
worksheet in the Global Warming material with description of activities cover:
1) Observing and Questionning to the aspect of Basic Question, 2)
Experimenting/ Data Collection or Information to the aspect of Designing
Project, 3) Associating/ Analysing Data and Information to the aspect of
Arranging schedule and Monitoring students- project progress, 4) Connecting to
the aspect of Result test and Evaluating experience; suitable to be implemented
in Senior High School Physics learning.
