Teachers are responsible for helping students to understand and admire subjects, which means they need first to appreciate what is supposed to be taught. Meanwhile, some intern teachers detest several subjects due to the unpleasant treatment received from their tutors. This study intends to clarify the definition of mathematical bitterness and develop its indicators. The respondents were seven third-year students at Pelita Harapan University, Indonesia. Data were collected using questionnaires and interviews and analyzed through descriptive qualitative with a phenomenological approach. The results showed that the indicators of bitterness in mathematics sprang from the following, 1) having experienced unpleasant treatment from a mathematics teacher for a long time, 2) having a negative view of mathematics, 3) feeling untalented in mathematics, 4) viewing the mathematics teacher as unfriendly, 5) poor mathematics learning performance, and 6) having high mathematical anxiety. The proposed definition of bitterness is a negative perception of mathematics that is built from the accumulation of past experiences that affect the student’s response to this subject. Hence, further studies are needed to provide solutions that help to heal students of their math bitterness.

Most students think that the hardest subject to understand is math. It happened when the student did not get the meaning of doing math. It was made worse by the covid situation, students more and did not get any value. Even though the government had provided curriculum and lesson method options to be held in class, still it can be maximized to create meaningful math lessons. Therefore, this research focuses on the application of the Project-Based Learning (PjBL) method based on a prototype curriculum to make math lessons more meaningful. The research method that will be used is descriptive qualitative. Students must get meaningful math lessons to find the greatness of God by doing math in their daily lives. Finally, students also glorify God. The research result is, PjBL based on the prototype curriculum method can help make learning mathematics more meaningful. The writer suggests for schools, hold training on using PjBL based on the curriculum prototype method, for teachers to apply this method in abstract topics, and for the next researcher to research the application of the PjBL method based on another curriculum.
