信息科技课程对于培育学生数字素养与技能至关重要,其高质量的教学实践对落实信息科技课标、推进教育数字化转型、建设数字中国具有重要战略意义。目前大部分研究多进行信息科技课程性质与特征、核心素养、建设路径等方面的理论探讨,缺乏对其教学实施效果的跟踪调研。为准确把握信息科技课程的实施现状,该研究构建和应用基于LICC范式的信息科技课堂观察量表,以12个信息科技课例为研究对象,从量化研究与质性研究相结合的视角对信息科技课堂跟踪观察分析。研究发现,信息科技课程教学实施成效初显,但仍然面临着一系列困境,如学生学习主体性与互动效率待提升,教师教学环节偏离教学目标且缺失连贯性、课程教学目标脱离素养培育、内容未凸显科学原理、评价弱化素养的监测、课堂教学平等民主性较低等。基于布迪厄实践逻辑理论的场域、惯习与资本三要素,对信息科技课程教学实施困境进行归因和剖析,可以认识到信息科技新教材与配套资源的短缺、信息科技教师课程能力水平低以及新教学理念与方法重构难度大三方面会促使信息科技课程的教学实施困难重重。因此,为促进信息科技课程教学实施有效开展,需要持续开发新教材与配套资源、不断提升信息科技教师课程能力水平、促进信息科技教师创新变革教学理念与方法。

《义务教育课程方案(2022年版)》提出,要培育学生课程核心素养,倡导将核心素养评价贯穿整个教学过程,达到“教—学—评”一致。然而,智慧课堂课程核心素养评价还存在很多问题。基于此,文章提出以教学为核心、理论与数据双向驱动的课程核心素养评价新范式。该范式包含课程核心素养理论模型构建、学习活动设计与实施、多模态数据采集与存储、相关特征的提取、评价模型的构建、评价结果的反馈应用六个环节,旨在实现以评促教、以评促学,提升学生的课程核心素养。文章还提出智慧课堂课程核心素养评价的原则:数字技术发展要以核心素养培育为目标、支持基于证据的过程性评价方法、创新情境嵌入式的评价手段、促进多元主体个性化评价反馈。
