In this research, students having online classes of a practical-based fabric design subject were encouraged to self-study from Open Educational Resource (OER) materials for a further and better understanding of their subject. Additionally, online materials were developed to improve students’ understanding via skill of digital literacy. Their learning progress was evaluated and compared to the face-to-face version. The majority of students found online classes combined with self-studying OER materials, potentially be a substitute for face-to-face classes. Most of the students further opined different OER videos assisted them without any face-to-face instructions in practical works, to develop new fabric samples from the inspiration. Analysis of test results, and comparison of students’ final grades with different learning modes, supported these phenomena.展开更多

Focusing on the design of equipment in-serviceassessment subjects, a design method for in-service assessment subjects basedon the combination of trial and training mode is proposed. Based on theactual use of high-equipment use management and training and the established indicator system, the army’s bottom-level equipment activity subjectsand bottom-level assessments are combined. The indicators are mapped andanalyzed. Through multiple rounds of iterations, the mapping relationshipbetween in-service assessment indicators and military equipment activitysubjects is established. Finally, the equipment activity subjects whose data iscollected (reflecting the underlying assessment indicators) are generated inservice assessment subjects. The orthogonal test method is used to optimizethe samples in the assessment subjects to form an in-service assessmentimplementation plan. Taking a certain type of armored infantry fightingvehicle as an example, the sample optimization design of the initially generatedin-service assessment subjects is analyzed. It provides methods and ideas tocarry out in-service assessment work.展开更多

An IL course was designed by subject librarians of National Science Library(NSL), Chinese Academy of Sciences(CAS), with three patterns addressing the development of graduate students' IL competencies.Research limitations: It is only about the practice of subject librarians at NSL, CAS, in designing IL courses for graduate students enrolling in graduate courses offered by College of Chemistry and Chemical Engineering, GUCAS.Practical implications: The results can provide a lot of useful information for the improvement of IL competencies of graduate students in science and technology disciplines.Originality/value: It is significant for assisting future subject librarians in incorporating IL skills into their course, especially for academic and research librarians to prepare and develop IL courses for science and engineering graduate students.展开更多
