This paper reports research results of the proposed experiential learning using a game-based educational material. The educational material was an application running on a mobile device and was supported for learners to study university library instruction. During the experiential learning, the learners answered several quizzes provided from the educational material. The quizzes were including experiential contents such as actually to find an academic journal or to reserve a learning room. In order to evaluate learning effectiveness of the experiential learning, this research made a comparative experiment. The experimental group used the educational material and the control group used another educational material of e-learning (non-experiential) but the contents was almost same as the contents of the experiential learning. The comparative experiment took several evaluation elements such as pre-/post-test scores, delayed-test scores and learning motivation scores based on IMMS of ARCS model. The experimental results revealed that experiential learning was superior for the several elements of these metrics. This research, furthermore, analyzed learner's operation data to the educational material and learner's behavior data during the learning in the experimental group. The analyzing results showed three types of the learning behaviors and indicated that an instructor needs to adopt suitable instructional design to each type to bring superior learning effectiveness. 相似文献

This article proposes the incorporation of learning science into the programming and operation of public libraries. Learning science, a multidisciplinary field spanning cognitive science, psychology, neuroscience, economics, anthropology, and linguistics, has identified proven methods for enhancing learning at any age. The article highlights some of the tools and insights that are most relevant to libraries in their role as centers for informal learning. 相似文献

The library literature evaluating the efficacy of online tutorial methods and delivery tools is a valuable resource for librarians looking for information to inform their choices for developing asynchronous online instruction. This literature, however, examines a wide variety of delivery tools, methods, and student populations. As a result, it is difficult to draw definitive conclusions about any one tutorial tool or method. This article compares selected research and concludes that the consensus in the literature suggests that applying adult learning principles to library tutorials has a larger impact on effective online instruction than the individual tool. 相似文献

This case study presents the development and implementation of a personal librarian program for a cohort-based, executive-style higher education administration doctoral program. Librarians and the program director collaborated to create a student-centered program based on individual research needs. The personal librarian program was designed to build a close relationship between the librarian and individual students; to help identify their research knowledge gaps; and to identify resources to meet each individual students' research needs. 相似文献

Many librarians struggle with how to balance scalable instructional offerings with more personalized instruction for online students—scale tends to come at the cost of personalization and vice versa. This paper will discuss three methods for connecting with online students that range from one-to-one personalization to widely scalable instruction: individual consultations, scaffolded instructional webinars, and asynchronous video tutorials. The student engagement with each type of instruction will be discussed, with ideas for future directions provided. 相似文献

当前的卫星资源分配方案大多为同步轨道卫星设计,针对低轨卫星的高动态特性,以及存在频率和功率资源受限的问题,提出一种基于深度强化学习的功率分配算法。首先对低轨卫星功率分配场景进行建模,引入一种时隙划分方案来简化低轨卫星的动态特性模型,进一步提出一种基于深度强化学习算法的功率分配策略,该策略通过调节单颗低轨卫星各个波束中子载波的功率值,降低同频干扰,能达到提升低轨卫星频谱效率的目的。仿真结果表明,所提算法能够在较短时间内收敛并达到稳定状态,在总功率一定的条件下,该方案能有效提升单颗低轨卫星的吞吐量,其频谱效率明显高于注水算法和Q学习算法。 相似文献
