as one of the materials to develop students'
Chemistry-literacy.
In previous study, Perdana (2017) has researched
on the development of electronic modules on
alkanes, alkenes, and alkalis topic using Learning
Cycle 5E learning method. Another study by
Nurlatifah (2013) has created an environment-based
Chemistry-literacy-oriented electronic module of
hydrocarbon. Previous studies tend to discuss the
topics that are already in textbooks and convert them
to electronic forms. In this study, Chemistry-
literacy-oriented electronic module was developed
on battery topic as the application of Voltaic cell. In
battery textbook resources, this topic is rarely
discussed in detail, even though the concept of the
battery has a relationship with Chemistry technology
associated with everyday life.
In this study also, the development of Chemistry-
literacy-oriented electronic module on battery topic
was done by analysing the results of validity test and
feasibility test.
2 METHODS
The research method used was the Design Based
Research (DBR) with series of ADDIE model steps
(Analysis, Design, Development, Implement, and
Evaluations) (Barab and Squire, 2004, p. 114).
The research procedure referred to procedure
Design Based Research (DBR), electronic module
according to Herrington et al. (2007), with the steps
as follows: 1) preparation phase (Analysis),
activities at this stage were the determination of
subjects, lessons, competencies to be developed,
learning achievement analysis, literacy analysis of
science and Chemistry, formulation of title,
collection of sources and materials, and selection of
software; 2) design phase (Design), the activities
included the collection of materials to be presented
in science-literacy-oriented electronic module on the
battery topic, such as text materials, phenomenon
texts, images, animations, audios, and videos; 3)
development phase (Development), this included
selecting the title, making the flow chart, making
content analysis and plan, storyboard preparation,
and generating the electronic module products; 4)
testing phase (Implementation), this included the
validation of electronic module by media experts
and topic experts, and the feasibility test to limited
respondents and revision according to the test
questionnaire result; 5) improvement phase /
revision of product (Evaluations), this was the
revision of the generated electronic module based on
suggestion of improvements from both experts.
The research instrument used was the Likert
enclosed type questionnaire with improvement
suggestion that aimed to test the validity of each
item of electronic module criteria. The Guttman
scale form of questionnaire was used to find out the
feasibility test seen from material presentation and
display aspects.
According to Arikunto (2010, p. 154), the result
of the Likert scale questionnaire addressed to the
validators was processed by looking at the number
of checks in each column, then multiplying the
frequency in each column with the corresponding
column values. The result of questionnaire
rcalculated was compared with the value of rcritical
resulting r = 0.30. If the value of rcalculated was
greater than 0.30, then the criteria was valid,
otherwise the criteria was invalid. The r calculation
uses the following formula:
Declaration:
rcalculated : validity value
x : number of respondents answer quality
n : number of respondents
N : the biggest number of questionnaire
According to Rivai and Sudjana (2009, p.
44), the data processing on the Guttman scale
questionnaire obtained from the test results to the
limited respondents, was done by summing the
entire value of the column and then converting it
into a percentage. A module or electronic module
has the eligibility criteria, with the following
percentage qualification (%): 90-100 was declared
very viable, 80-89 was declared feasible, 70-79 was
declared less feasible, and < 60 was declared not
feasible. The percentage was calculated by using the
following formula:
Declaration:
% : the percentage of feasibility
: the number of respondents answering
yes and no
N : the total
respondents
The subject of the study consisted of subjects for
validity and feasibility test which can be described
as follows: 1) the subjects of validity test were a
topic expert and a media learning expert (lecturer of
Chemistry education and lecturer of Informatics
departments); 2) the subject of the feasibility test
were students of 4th and 6th semesters, as many as
10 students who have received the Voltaic cell
material and its application.
