This
study aims to describe the process of developing the device and producing a
good quality guided inquiry model mathematics learning tool on linear program
material for class XI SMA, and to describe the effectiveness of guided inquiry
model mathematics learning which can train students' critical thinking skills
on linear program material.
This
type of research is development research. The learning tools developed in this
study are the Learning Implementation Plan (RPP), Student Worksheet (LKPD), and
Critical Thinking Ability Test (TKBK). The learning tools are developed using a
4-D development model which consists of four stages, namely the define stage,
the design stage, the develop stage, and the disseminate stage. The research
subjects for the trial class were 13 students of class XI MIPA 3 and the
research subjects for the implementation class were 17 students of class XI
MIPA 1. In this study using descriptive analysis.
Based
on the results of descriptive analysis, it was found that the learning tools
developed were of good quality because they met valid, practical, and effective
criteria. The learning device is said to be valid because all validators give a
minimum score of 3 for each aspect of the assessment on a scale of 1 - 4 and
the critical thinking ability test questions meet the valid, reliable, and
sensitive criteria. The learning device is said to be practical because the
teacher's activities in managing learning meet good criteria and the activities
of students meet the active criteria. Learning devices are said to be effective
because students 'responses to learning devices and learning activities meet
the positive category, guided inquiry mathematics learning model to train
students' critical thinking skills is achieved.
Based
on the descriptive analysis in the implementation class, it was found that
guided inquiry mathematics learning model on linear program material was
effective for training students' critical thinking skills. This can be seen in
the aspects of the quality of learning, the appropriateness of the level of
learning, incentives, and the time used are in accordance with the planning
that has been prepared in the lesson plan (RPP), as well as guided inquiry
learning mathematics to train students' critical thinking skills to be
achieved.
