Abstract

At the beginning of each semester, subjects scheduling is always carried out by the curriculum representatives and academic staff. There were several problems that must be avoided in subjects scheduling, these problems were the schedule of teachers who teach one subject at the same time are scheduled in different classes, teachers who teach more than one subject are scheduled in the same class at the same time, teachers who are lack of scheduled for teaching. In the subject of graph theory, there is a concept of graph coloring, one of which is vertex coloring. In vertex coloring, there is a Welch-Powell Algorithm application which produces a color for each vertex. In subject scheduling, it is assumed that the vertex is the subject and the teacher, while the edge is the class. In vertex coloring, graph vertices are colored so that there's no two neighboring vertices have the same color. The aim of this research was to arrange a lesson schedule so that problems do not occur such as clashes between teachers, subjects, and teaching hours. The method used in arranging this lesson schedule used the Welch-Powell Algorithm. The results obtained were using the Welch-Powell Algorithm to produce a lesson schedule every day where if there are two classes that have the same subject, they can meet the same day requirements but come in different hours and get a lesson schedule that has no clash between teachers, subjects, and teaching hours.

Abstract

Learning activities were carried out online or the Online Learning Model (OLM) in the era of the Covid-19 pandemic. Every student who participates in OLM is trained in critical thinking and regularly improves the solving of a mathematical problem. This research used qualitative research with a descriptive approach. Researchers were interested in identifying critical thinking standards of analysis at the Novice Performance Level with the Online Learning Model (OLM) in Geometry Lectures in solving geometric problems based on students' Critical thinking skills with analysis indicators. Subjects were taken based on the assignment score on the material. Subjects were grouped into 3 abilities, namely low ability (Re), medium ability (Se), and high ability (Ti). The number of subjects was three people who were taken from each group at each level. Data were collected using 2 mutually supporting instruments, namely the test instrument and the interview instrument. The validation used was expert validation and content validation. The results showed that online learning activities or the Online Learning Model (OLM) can be identified that subjects with low abilities fulfill all indicators in the analysis stage, while not meeting all indicators for moderate and high student abilities because the Novice performance level is in accordance with its understanding, namely the lowest level where the subject had not been able to solve the given problem at all.
