The purpose of this study was to examine the online mathematics learning process at SD Muhammadiyah Bojong Nangka, measured from context, input, process and product variables. This research is a type of evaluation study research. The subjects in this study were 5 grade III mathematics teachers and 194 grade III students at SD Muhammadiyah Bojong Nangka. The data were collected through a questionnaire as the main instrument, interviews and documentation study data as a supporting instrument. The data analysis technique is descriptive quantitative by using the z-score formula which is then converted into t-scores. The z-score result is converted into the prototype quadrant of Glickman's theory. The results of the data analysis showed that the students explained the components of the + value context, input -, process -, and product -. Based on the Glickman prototype, the online mathematics learning process for students at SD Muhammadiyah Bojong Nangka is in quadrant III which is classified as less effective. The teacher states the components of the value +, input +, context - and input +. Based on the Glickman prototype, the online mathematics learning process for teachers at SD Muhammadiyah Bojong Nangka is in quadrant II which is classified as effective. Based on these findings, it can be concluded that the online mathematics learning process at SD Muhammadiyah Bojong Nangka for students is classified as less effective and for teachers is classified as effective in terms of context, input, process and product variables.
