Carry out the Library Services and Literature Retrieval Course Using Blended Learning with the Intelligence Services System to Enhance Students' Literature Retrieval Knowledge and Skills

Background and Aim: This study focuses on exploring the implementation of library services and literature retrieval courses based on blended learning and intelligence service systems, to enhance students' knowledge and skills in literature retrieval and ensure that they can fully grasp the entire process of literature retrieval. Through practical operation and practice, stimulate students' interest and enthusiasm for learning, and improve the efficiency and accuracy of retrieval. This research aimed to compare students' literature search knowledge and skills before and after course implementation. Materials and Methods: This study experimented with 30 first-year students from the School of Literature, Zhoukou Normal University, in the second semester of the 2024 academic year, using the cluster random sampling method. This study adopts a blended learning and intelligence service system to develop library services and literature retrieval courses, and provides students with scoring criteria for literature retrieval knowledge and skills before and after implementation. The research instruments were 1) a course document and 8 lesson plans, which were evaluated by 5 experts, revealed that the mean scores of the course document were 4.74 (SD=0.40) and the mean scores of the 8 lesson plans ranged from 4.53-4.65 (SD=0.51-0.60). 2) The test paper used to evaluate and measure students' literature retrieval knowledge showed that the Item-Objective Congruence values range from 0.6-1.00. The difficulty range for quality analysis of performance tests is 0.53-0.77, and the discrimination range is 0.44-0.75. Reliability analysis was conducted on 30 questions in the test paper, and the result was 0.866, which meets the reliability standard. 3) Scoring rubric for measuring the literature retrieval skill showed that the Item-Objective Congruence index ranges from 0.6-1.00. The reliability analysis of the scores of 30 students using seven skills resulted in 0.725, which meets the reliability standard. The data was analyzed by using mean, standard deviation, and a t-test for dependent samples. Results: Research findings were found as follows: (1) The comparison of literature retrieval knowledge before and after implementing library services and literature retrieval courses based on blended learning and intelligence service systems revealed that the posttest scores (M=21.3, SD=2.11) were higher than pretest scores (M=18.9, SD=1.76) at the .01 level of statistical significance (t29=17.06, p=0.001). (2) The mean scores of literature retrieval skill after implementing the library services and literature retrieval course based on blended learning and the intelligence service system were 17.4 out of 21, with a standard deviation of 2.28, which was higher than the criterion of 70% at a statistical significance level of.01 (t29=6.55, p=0.001). Conclusion: The library service and literature retrieval course based on blended learning and an intelligent service system developed has a significant impact on improving the knowledge and skills of literature retrieval for university library majors. Through this course, students learn to clarify the standardized process of "Determine the search topic → Determine the search keywords → Choose the right database → Search（ Enter keywords in the database）→ Filter the results → Read and evaluate the literature → Record and sort out the literature", avoiding the blindness of information acquisition, enabling students to accurately locate the required literature, reduce ineffective search time, and enhance search efficiency.
