农村基础教育应适当体现农村特色

农村学生身心的全面发展和社会的发展都需要农村基础教育适当培养学生具有与农村相关的基本素养,同时适当开发、利用农村得天独厚的教育资源,也有助于学生各方面素养发展。因此,农村基础教育应该在政府有关部门和其他方面力量的支持之下,通过自身积极的、创造性的工作,适当地、有效地开发利用农村的教育资源,从而有效地促进学生身心的全面发展,促进其与农村相关的基本素养的养成,使农村基础教育的改革与发展既符合教育改革与发展的一般要求,又在其培养目标、教育内容与教育方式等方面适当地体现农村的特色。     

3D技术教育应用创新透视

3D技术是虚拟现实、实时仿真和交互三维设计结合产生的关键技术,包括3D显示技术、3D虚拟现实技术和3D打印技术。目前3D技术已成为桌面技术(3D显示技术和3D虚拟现实技术为桌面显示技术,3D打印技术为桌面制造技术),正逐渐在知识创新、深度学习、虚拟实验、技能训练等方面彰显优势,为教育应用创新提供新环境、新平台、新资源、新工具和新范式。然而由于产品价格较为昂贵,后续的保养、管理及维修等费用也较高,3D技术教育应用在顶层设计、技术支持、教育资源、测评标准、应用领域、人才培养等方面仍面临较多困难。3D技术教育应用是一个教育生态系统,是依托3D技术、资源、工具、平台、产品、人才和课程,构建教学资源、教学媒体和教学产品的设计、开发、运用、管理和评价的教育系统,需要进行理论、技术与应用的协同推进,从生态发展、产业推进、深度融合视角开展研究。在落实《教育信息化十年发展规划(2011-2020年)》之际,应将"3D技术教育应用创新"作为技术与教育"深度融合"的重要途径,构建3D教育应用生态系统环境,促进教学方式与学习方式变革,以此应对第三次工业革命带来的机遇和挑战。

Development and implementation of a three-dimensional (3D) printing elective course for health science students

Three-dimensional (3D) printing technology has become more affordable, accessible, and relevant in healthcare, however, the knowledge of transforming medical images to physical prints still requires some level of training. Anatomy educators can play a pivotal role in introducing learners to 3D printing due to the spatial context inherent to learning anatomy. To bridge this knowledge gap and decrease the intimidation associated with learning 3D printing technology, an elective was developed through a collaboration between the Department of Anatomy and the Makers Lab at the University of California, San Francisco. A self-directed digital resource was created for the elective to guide learners through the 3D printing workflow, which begins with a patient's computed tomography digital imaging and communication in medicine (DICOM) file to a physical 3D printed model. In addition to practicing the 3D printing workflow during the elective, a series of guest speakers presented on 3D printing applications they utilize in their clinical practice and/or research laboratories. Student evaluations indicated that their intimidation associated with 3D printing decreased, the clinical and research topics were directly applicable to their intended careers, and they enjoyed the autonomy associated with the elective format. The elective and the associated digital resource provided students with the foundational knowledge of 3D printing, including the ability to extract, edit, manipulate, and 3D print from DICOM files, making 3D printing more accessible. The aim of disseminating this work is to help other anatomy educators adopt this curriculum at their institution.     

Digital body preservation: Technique and applications

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology—digital body preservation—is presented for combining and matching scan geometry with radiographic imaging. The technique encompasses joining layers of 3D surface scans in an anatomical correct spatial relationship. To do so, a computed tomography (CT) volume is used as template to join and merge different surface scan geometries by means of nonrigid registration into a single environment. In addition, the use and applicability of the generated 3D models in digital learning modalities is presented. Finally, as computational expense is usually the main bottleneck in extended 3D applications, the influence of mesh simplification in combination with texture mapping on the quality of 3D models was investigated. The physical fidelity of the simplified meshes was evaluated in relation to their resolution and with respect to key anatomical features. Large- and medium-scale features were well preserved despite extensive 3D mesh simplification. Subtle fine-scale features, particular in curved areas demonstrated the major limitation to extensive mesh size reduction. Depending on the local topography, workable mesh sizes ranging from 10% to 3% of the original size could be obtained, making them usable in various learning applications and environments.
