Abstract. The purpose of this study was to describe students' difficulties in solving problem solving problems in Algebra and Trigonometry courses. Subjects in this study were students of the Mathematics Education Faculty of Unika Santo Thomas Faculty of Teaching and Education study program in North Sumatra in semester 1 of the 2017-2018 school year, totaling 10 people. The data collection tool used in this study was a test of 5 questions in the form of a description. This type of research is a qualitative descriptive study. Data collection techniques are carried out by tests, observation, interviews and documentation. Data analysis techniques were carried out with the stages of data reduction, data presentation and conclusion drawing. The results showed that students had difficulty using the concept of equality and inequality squared, the use of the concepts of trigonometric formulas. Students also have difficulties in using number sequence principles and completing trigonometric equation solving, difficulties in disclosing information from problem solving and calculation errors. The contributing factor is the existence of several concepts and principles of algebra and trigonometry that are used in solving problems that have not been well controlled by students and are less thorough in performing calculations.Keywords: Analysis of Learning Difficulties, Algebra and Trigonometry

 This research was conducted based on the findings of college students. A phenomenon that is often found in students is that students still have low listening ability. This happened to students of the 2020 UNIPA Indonesian Language Education Study Program (PBI). The low value of listening ability in students was due to the lack of teaching materials for listening courses. To reduce or minimize the occurrence of language errors, lecturers use the Four-D Model or the 4D Model. Through the Four-D Model or the 4D Model, this study develops a product, namely the "Listening Research Procedure" module, using 4D steps, namely define, design, development, and dissemination. To analyze the data, this study used descriptive qualitative and quantitative. Based on data analysis, the process of making the Listening module is in accordance with the Thiagarajan development procedure known as Four-D Models (4D Model). The quality of the Listening module is viewed from the aspect of content feasibility, language eligibility, obtaining validation validation with good criteria. The results of the tests conducted by students showed that they had progressed, the average score of the students had complete information.
