Students' mathematical problem-solving skills are relatively low.
Consequently, planning learning activities that can facilitate students'
mathematical skills are needed. Teachers can use a cooperative learning model
with a group investigation type to facilitate students' mathematical problemsolving
skills. The implementation of the learning model must be supported by
good learning instruments such as a syllabus, lesson plan, and worksheet that are
appropriate to the students’ conditions and needs. Based on the results of
interviews with some junior high school teachers, the commonly used learning
instruments were downloaded from the meeting results of the Teacher Association
(MGMP) so the instrument may not be suitable for the needs of students and need
improvement. This study aims to develop a cooperative model-based learning
instrument of group investigation type that meets valid and practical criteria to
facilitate students' mathematical problem-solving skills in the two-variable linear
equation system.
This research and development (R&D) produced a learning instrument
consisting of a syllabus, lesson plan, and worksheet. The development model
followed the 4D model covering define, design, develop, and disseminate.
However, this study was limited to the develop stage as the initial objective of this
study was to produce a valid and practical product.
The development procedure consisted of 1) the define stage which includes
(a) initial-end analysis, (b) student analysis, (c) task analysis, (d) concept
analysis, and (e) specific instructional objectives; 2) the design stage which
includes (a) preparation of test criteria, (b) selection of media, (c) selection of
formats, and (d) initial design; and 3) the develop stage which includes (a) expert
appraisal and (b) development testing.
The instruments used in data collection were 1) validation sheets
containing aspects of assessment to assess the validity of the syllabus, lesson
plans, and worksheet, and 2) student response questionnaires to the worksheet.
The learning instrument is considered valid with revisions or without revisions
with a percentage of more than 70%. Besides, if the result was higher than 60%,
then the worksheet is considered practical.
The validity of the learning instrument was checked by three lecturers who
are experts in mathematics education. The results of data analysis showed an
average percentage of syllabus validity of 87,67% with very valid criteria, an
average percentage of lesson plans validity of 91,89% with very valid criteria,
and an average percentage of worksheet validity of 89,56% with very valid
criteria. The overall results of the assessment of the three experts on the syllabus,
lesson plans, and worksheet were very valid. This means that the developed
syllabus, lesson plans, and worksheets may be used with some revisions for
improvements.
xv
One-to-one assessment to determine the readability of the worksheet
involved five students and obtained an average of 86,42% with very practical
criteria and good readability so that the worksheet can be used for limited trials
in the field. Furthermore, the researcher conducted a small group trial of 15
students and obtained an average of 89,71% with very practical criteria. This
indicates that the developed learning instrument is ready for use in learning
activities.
Key Words : Learning Instrument, Cooperative Model of Group Investigation
Type, Mathematical Problem Solving-Skill.
