A Development of Students’ Worksheet Based on Contextual Teaching and Learning

Abstract

This research is aimed at developing the students’ worksheet
to determine the quality of validity and practicality aspects based on
expert’s assessment of materials, expert’s design, media specialists, an
individual assessment of students’ testing, a small group assessment of
students trial, and a field trials assessment of students. This study is
adapted from the development of ADDIE model which consists of 5
stages: 1) Analysis, 2) design, 3) Development, 4) Implementation, and
5) evaluation. The results showed that the quality of students' worksheet
of mathematics on materials of factorization in algebra-based on
Contextual Teaching and Learning basically on the assessment of: 1) the
experts’ of subject materials is obtained a total average of 3.81 is
included in the category of "Good" or scored 76.2 % which is included in
the category of "Very Decent", 2) the experts’ design is obtained a total
average of 3.62 which is included in the category of "Good" or scored
72.4% which is included in the category "Decent", 3) the experts’ of
media is obtained scored 4:43 which is included in the category of
"Good" or scored 88.6% which is in the category of "Very Decent".
Whereas, the assessment by the students is done in three stages: 1) an
individual assessment of students’ testing is obtained average total of
4.75 which is included in the category of "Very Good" or 95% which is
included in the category of "Very Decent", 2) a small group assessment
of students trial is obtained total average of 4:58 which is included in the
category of "Very Good" or scored 91.6% thus it is included in the
category of "Very Decent", 3) a field trials assessment of students is
obtained a total average of 4:43 which is included in the category of
"Very Good" or scored 88.6% thus it is included in the category of "Very
Decent". Thus mathematics on materials of factorization in algebrabased                                                                                                                                on Contextual Teaching and Learning (CTL) is declared valid and
practical so it can be used as the learning equipment of mathematics at
the factorization material algebra.
