3.2 Expert Review
At this stage thematic paper studentis evaluated by
experts. The criteria used in determining the
validator in this study based on the assessment that
the experts have been experienced in assessing the
products to be developed. There are two validators
involved at this stage that the material expert is
required to test the material feasibility or the
accuracy of the contents and questions in accordance
with the competencies and learning objectives to be
achieved. Media experts are required to assess the
look/ design and language to be used. The
procedures used at this stage with the provided
questionnaire. Furthermore, the suggestions
provided by the validator are analyzed and then used
as revision materials. If there are things that need to
be improved then the researcher should revise the
student work sheet. If it has been declared valid then
thematic paper studentthat has passed the expert
review stage will then be done one-to-one
evaluations. Validity test is done to test the level of
validity and student work sheet, involving 2 experts
namely design experts and materials. The average of
the total validation score of experts is 3.77 with very
valid category. Both validators allow product testing
after revision in accordance with the suggestions that
have been made.
3.3 One-to-One Evaluation
In this one-to-one evaluation phase, the researcher
involves three students of group B Pembina 2 state
kindergarten Palembang representing students with
low, medium and high ability (Tessmer, 1993). Then
they are asked to do the work on the student work
sheet. The selection of research subjects is reviewed
from the level of ability. Average score from one-to-
one evaluation stage is 95% with very practical
category. While small group stage involving 9
students in group B3 with average value of 92%
with very practical category. After thematic paper
studenthas had its practicality in the one-to-one
evaluation stage then thematic paper student which
has been revised through expert test called prototype
2 continued to small group evaluation stage.
Media validation stage consisting of 4 indicators
such as 1) clarity of writing on student work sheet,
writing not blurred, no errors in writing, thematic
paper studentwriting interesting to read and the type
of letters used can be read, with a total score of 22,
2) instructions for use which consists of the
language used effectively and efficiently and the
clarity of the information provided, with a total score
of 8, 3) clarity of the image on thematic paper
studentthat is not blurred image, strategic image
position, there is an explanation, the picture is easy
to understand and get the total score 15, 4) display
thematic paper studentconsisting of images in
accordance with the theme and sub theme,
interesting to see, drawings arranged regularly and
there are titles along with other information, the total
score obtained 16. Average score obtained in the
design evaluation stage of 3.78 with the category
very valid. Then it is worth to be tested according to
suggestion. Suggestions obtained by the researcher
in the form of spelling or writing repaired, the title
moved to the top center of the worksheet, the size of
the title is enlarged and make the steps of learners.
After the suggestion of the validator is fixed then it
is feasible to be tested.
The validation of the material/ content of 3.76
with the category is very valid, then for the design
validation of 3.78 with the category is very valid.
Thus, thematic paper student developed by the
researcher can be used in the next test phase. Based
on the suggestion of the validator then there are
some revisions on prototype 1 as described in the
previous step. Furthermore, the validated and
revised thematic paper studentis then tested at the
one to one evaluation stage. Overall the average
value of expert validation review results on the
theme thematic paper studentmy homeland sub
theme of Palembang city is 3.7 with very valid
category. In line with the results of the researcher,
Bronwyn H. Hall (2006) Research and Development
(R&D) is the term commonly used to describe the
activities undertaken by firms and other entities such
as individual entrepreneurs in order to create new or
improved products and processes. All components of
the learning product are consistently related to one
another called construct validity. The indicators used
to infer the developed learning product are valid, the
validity of the content and the validity of the
constructs. In line with the expert opinion above
according to According to H. E. Garrett (1965) the
validity of a test or any measuring instrument
depends upon the fidelity with which it measures
what it proposes to measure.” According to Freeman
(1960) an index of validity shows the degree to
which a test measures what it purposes to measure
when compared with accepted criteria. According to
Anastasi (2007) “The validity of a test concerns with
what the test measures and how well it does so.
The one to one stage aims to see the practicality
of prototype 1 that has been evaluated by the expert.
This stage of teachers teach children about the city
of Palembang which refers from the theme of my
