【摘要】：理科教學(xué)中涉及很多抽象概念,學(xué)生無感性認識基礎(chǔ),在現(xiàn)有的認知發(fā)展水平上難以科學(xué)感知與建構(gòu)這些概念。手持技術(shù)是一種先進的教育信息技術(shù),能定量采集理科教學(xué)中的各種常見數(shù)據(jù)并呈現(xiàn)直觀可視的曲線圖像,將其作為認知工具有助于學(xué)生克服抽象概念學(xué)習(xí)中的認知難點。文章根據(jù)認知建構(gòu)主義學(xué)習(xí)理論,從心理學(xué)角度分析學(xué)習(xí)者如何借助手持技術(shù)實驗進行抽象概念學(xué)習(xí),首次提出"多重轉(zhuǎn)化、比較建構(gòu)"認知模型,該模型認為手持技術(shù)支持下的概念學(xué)習(xí)是陌生概念到認知結(jié)構(gòu)已有概念之間的轉(zhuǎn)化,一般物質(zhì)到具體物質(zhì)之間的轉(zhuǎn)化,定性認知到定量認知的轉(zhuǎn)化,數(shù)據(jù)認知到圖像認知的轉(zhuǎn)化以及在比較參照中進行抽象概念建構(gòu)等認知過程。并以"溫室效應(yīng)"概念學(xué)習(xí)為例,闡明該模型如何應(yīng)用于教學(xué)實踐,旨在豐富手持技術(shù)在概念認知領(lǐng)域的研究內(nèi)容,并為教育信息化進程中科學(xué)有效開展基于手持技術(shù)的信息化概念教學(xué)提供參考依據(jù)。
[Abstract]:There are many abstract concepts involved in science teaching, students have no basis of perceptual cognition, and it is difficult to perceive and construct these concepts scientifically in the present level of cognitive development. Handheld technology is an advanced educational information technology. It can collect various kinds of common data in science teaching quantitatively and present visual curve images, which can be used as a cognitive tool to help students overcome the cognitive difficulties in abstract concept learning. Based on the cognitive constructivism learning theory, this paper analyzes how learners learn abstract concepts with the help of handheld technology experiments from the perspective of psychology, and puts forward for the first time a cognitive model of "multi-transformation, comparative construction". The model holds that concept learning supported by handheld technology is the transformation from unfamiliar concept to existing concept of cognitive structure, from general substance to concrete substance, from qualitative cognition to quantitative cognition. The cognitive process from data cognition to image cognition and abstract concept construction in comparative reference. Taking the concept learning of Greenhouse Effect as an example, this paper illustrates how the model can be applied to teaching practice in order to enrich the research content of handheld technology in the field of conceptual cognition. It also provides a reference for carrying out the concept teaching of informatization based on handheld technology in the process of educational informatization.
