This research uses a class action research approach. Each cycle consists of several stages, namely: planning, action, observation, and reflection. At the planning stage consists of learning plan preparation activities, the preparation of research instruments, at the action stage includes the activities of providing action in the form of learning in accordance with the learning design that has been formed in accordance with the principles of discovery learning combined with NHT Cooperative Learning Type, the observation stage includes observation activities on student activities during learning, especially during discussions and the implementation of actions and obstacles encountered, and the reflection stage is a reflection of the implementation of learning activities based on observations and results of critical thinking skills through insertion tests. Matters of concern at this stage of reflection are the assessment of the implementation of actions, the obstacles that arise, and the progress that has been achieved. To obtain research data two types of research instruments were used. The research instrument in question is the observation sheet of the implementation of learning and observation guidelines as well as test questions on critical thinking skills at the end of the cycle.

The research begins with a survey on whether learning mathematics requires media, then identifies the frequency with which teachers use media in learning mathematics, as well as the reasons teachers never or rarely use media in learning mathematics. Based on the survey, it was found that teachers need reference books to develop mathematics learning media, so it is necessary to develop the criteria for the required reference books. Furthermore, a literature review was conducted to compare the needs (ideal conditions) for Learning Media reference books with the current state (real conditions). Conclusion The results of the study show that the materials that require media are: arithmetic operations Integers and fractions, Linear Equations, Sets and Venn Diagrams, geometry, Function values, function graph sketches, slopes of lines, Pythagoras, circles, tangents, inner circles and the outer circle of a triangle, the properties of geometric figures, similarity, congruence, cylinders, cones, and spheres. In addition, the media needed are Concept Maps, Informative Power Points, Interactive Power Points, Student Worksheets, Learning Videos, Teaching Aids, and GeoGebra.
