With the continuous development of higher education, the evaluation of college students' learning has received increasing attention. Understanding the impact of the multiple evaluation system on college students' sense of English learning acquisition is of great significance. It helps educators to better design teaching activities and evaluation methods. This study focuses on 90 freshmen enrolled in the course of "College English." Using research tools and methods such as questionnaire, classroom observations, and online tests, the research is to explore the impact of diverse evaluation methods on students' sense of achievement. The findings show that there is a significantly positive correlation between students' learning behaviors, such as the degree of learning engagement and learning methods, and students' sense of knowledge acquisition. There is a significantly positive correlation between teachers' teaching behaviors such as teaching methods and teaching design, and students' sense of ability acquisition. There is a significantly positive correlation between the learning environment such as timely feedback on student' learning and assessment methods, and students' sense of emotional acquisition. Diversified assessment methods can enhance students' interest in learning, increase their level of engagement, improve their participation in the course, and enhance their sense of achievement. The authors suggest that it is necessary to utilize the learning situation data of the knowledge graph to conduct multi-dimensional and multi-level course evaluations for students, so as to improve students' sense of acquisition in terms of knowledge, abilities and emotions.
