One of the main factors that determine the quality of instruction is the teaching ability of the instructor administering the class. To evaluate teaching ability, methods such as peer review, student feedback, and teaching portfolio can be used. Among these, because feedback from the students is directly associated with how well the students feel they have learned, it is essential to improving instruction and teaching ability. The principal aim of instruction evaluation lies in the evaluation of instructor's qualification and the improvement of instruction quality by enhancing professionalism. However, the mandatory instruction evaluations currently being carried out at the term's end in universities today have limitations in improving instruction in terms of its evaluation items and times. To improve the quality of instruction and raise teaching abilities, instruction evaluations should not stop at simply being carried out but also be utilized as useful data for students and teachers. In other words, they need to be used to develop teaching and improve instruction for teachers, and consequently, should also exert a positive influence on students' scholastic achievements and learning ability. The most important thing in evaluation is the acquisition of accurate information and how to utilize it to improve instruction. The online instruction diagnosis item pool is a more realistic feedback device developed to improve instruction quality. The instruction diagnosis item pool is a cafeteria-like collection of hundreds of feedback questions provided to enable instructors to diagnose their instruction through self-diagnosis or students' feedback, and the instructors can directly select the questions that are appropriate to the special characteristics of their instruction voluntarily make use of them whenever they are needed. The current study, in order to find out if the online instruction diagnosis item pool is truly useful in reforming and improving instruction, conducted pre and post tests using 256 undergraduate students from Y university as subjects, and studied the effects of student feedback on instructions. Results showed that the implementation of instruction diagnosis improved students' responsibility regarding their classes, and students had positive opinions regarding the usefulness of online instruction diagnosis item pool in instruction evaluation. Also, after instruction diagnosis, analyzing the results through consultations with education development specialists, and then establishing and carrying out instruction reforms were shown to be more effective. In order to utilize the instruction diagnostic system more effectively, from planning the execution of instruction diagnosis to analyzing the results, consulting, and deciding how those results could be utilized to instruction, a systematic strategy is needed. In addition, professors and students need to develop a more active sense of ownership in order to elevate the level of their instruction.

수학적 모델링은 일반적으로 수학적인 방법으로 해석되고 이해되어야 하는 실제적인 문제 상황을 해결하기 위해 상황에 대한 적절한 수학적 모델을 구성하여 문제를 해결하는 일련의 과정이라고 할 수 있다. 문장제는 실제적인 측면과 형식적인 측면, 모두를 포함하고 있으므로 수학적 모델링 활동에 이상적인 도구가 될 수 있다. 이에 본 연구는 실세계의 맥락을 고려해야 하는 진정성있는 문장제를 바탕으로 한 수학적 모델링 학습이 문장제 해결 행동, 문장제 해결에서 실생활 경험을 활용하는 능력, 문장제에 대한 신념 등에 미치는 영향을 조사하였다. 연구 결과 문장제에 대한 수학적 모델링 학습은 직접번역 접근(DTA) 대신에 의미기반 접근(MBA)으로 문장제 해결 행동을 이끄는데 효과적이었으며, 문장제를 해결하는데 있어서 실생활 맥락을 고려하는 태도에 긍정적인 영향을 미쳤다. 또한 수학적 모델링 학습은 문장제에 대한 긍정적인 신념을 형성하는데 중요한 역할을 했음을 알 수 있었다. 이와 같은 연구 결과를 바탕으로 초등학교에서 문장제를 어떻게 다루어야 하는지에 대한 시사점을 살펴보았다.
