项目摘要

The literature has demonstrated the challenge for VI learners in gaining an understanding of the code structure when using text based programming languages (TBLs) and it is my view that physical programming languages (PPLs) have the potential to overcome this issue. An important concept in primary computing education is control flow; In order to be able to develop an understanding of control flow a learner first needs to be able to interpret or read code. Unlike TBLs, PPLs cannot be read in the traditional sense and their tangible nature lends themselves to exploration through touch, particularly for visually impaired learners. The techniques we use to gain information about a specific property of an object can be thought of as an exploratory procedure (EP) (Lederman and Klatzky, 1987) and this term could equally be applied to the techniques learners employ to explore physical programs.My research aims to identify the EPs that are employed by visually impaired children when working with PPLs and to investigate how these EPs can provide an insight into the learning processes associated with control flow. The specific research questions are outlined below:1) What exploratory procedures do VI children in primary education employ when working with physical programs?2) How do the exploratory procedures of VI children change as an understanding of control flow develops?3) To what extent can an understanding of the different exploratory procedures employed be used to support VI children develop an understanding of control flow?

文献已经证明了VI学习者在使用基于文本的编程语言（TBL）时理解代码结构的挑战，我认为物理编程语言（PPL）有潜力克服这个问题。初级计算机教育中的一个重要概念是控制流;为了能够理解控制流，学习者首先需要能够解释或阅读代码。与任务型语言不同，PPL不能以传统意义上的方式阅读，其有形的性质有助于通过触摸进行探索，特别是对视障学习者来说。我们用来获取关于一个对象的特定属性的信息的技术可以被认为是一个探索过程（EP）（Lederman和Klatzky，一九八七年）这个术语同样适用于学习者探索物理课程所使用的技术。我的研究旨在识别视障儿童在与PPL合作时使用的EP，并调查这些EP如何提供洞察力，与控制流相关的学习过程。具体的研究问题概述如下：1）在小学教育中，VI儿童在参与体育项目时采用了哪些探索性程序？2)随着对控制流理解的发展，VI儿童的探索过程是如何变化的？3)在多大程度上可以使用不同的探索程序的理解，以支持VI儿童发展控制流的理解？
