Analysis of Students’ learning of computer programming in a computer laboratory context

ABSTRACT

Previous research shows that many students find it difficult to learn computer programming. To learn computer programming includes both gaining theoretical understanding and learning to develop programmes in practice. To this end, teachers commonly design programming exercises for the students in the computer laboratory. To be able to improve the process of designing such exercises, there is a need of a more detailed understanding of the interaction between learning of theory and learning of practice in laboratory sessions. In this paper, an approach for investigating this interaction is proposed. Theoretically, the approach is based on phenomenography and variation theory. To illustrate the approach, it is demonstrated in detail how it was applied to a small but rich case of empirical data from a computer laboratory session. The main result presented here is the new approach for analysing data. In addition, the results of the case study shed preliminary light on the interaction between learning of practice and learning of theory when students work with programming assignments in the laboratory.     

Hybrid heuristic and mathematical programming in oil pipelines networks： Use of immigrants

We solve the problem of petroleum products distribution through oil pipelines networks. This problem is modelled and solved using two techniques: A heuristic method like a multiobjective evolutionary algorithm and Mathematical Programming. In the multiobjective evolutionary algorithm, several objective functions are defined to express the goals of the solutions as well as the preferences among them. Some constraints are included as hard objective functions and some are evaluated through a …

Three cases of hybridity in learning spaces: Towards a design for a Zone of Possibility

The paper contributes to design discourse by drawing on Educational Design Research (EDR) that has been conducted into what we call a Zone of Possibility (ZoP) over the past seven years. We define a ZoP as a place where individuals can overcome the constraints of expectations and power structures to effect desired change. Specifically, this paper presents details of how our initial research question (RQ1) has evolved to the one presented in the conclusions (RQ2); both RQs are summarised below in the section “Research Questions.” To describe this evolution, the paper is presented as 3 cases (Confer, ZoP Stokes Croft and Google Lens in HE) that have provided insights to explore the concept of the ZoP and its implications for EDR. Specifically, one of the main conclusions is the importance of bridging positioning practices as “successful communication” and an understanding of social context in hybrid contexts (ie, the ZoP).     

AOP技术的研究与探讨

通过介绍一种新的程序设计方法——面向方面编程方法(AOP)。这项新的编程技术弥补了面向对象编程技术在处理横切关注点时的不足。使用该方法,开发者可以开发出易于设计、理解和维护的系统,能有效地提交代码的质量。在此基础上就AOP产生的背景、基本概念以及它的研究方向和应用热点进行了重点分析。

身心语言程式视阈下的信息检索用户认知模型研究

当今的科技信息发展环境中,信息检索用户的认知行为和需求心理极为复杂.如何将信息检索中用户的潜意识显现出来,以便更好地服务于检索系统建设,是信息检索研究中的核心难题之一.研究基于流行于欧美国家及港台地区多年的身心语言程式(NLP)理论,从身心、语言和程式三个核心维度出发,构建了信息检索用户的"需求认知、表达与交互模式"、"检索语言认知、表达与交互模式"和"检索目标制定中的心理取向模型".同时结合MP中的锚理论,分析信息检索用户的"心锚"和相关的"空间锚",总结出相应的信息检索规律,构建出检索中锚交互模型、集合关系、双因子矩阵模型和表达式,并对相关的假设模型进行数据检验和优化.     

Applying ‘what works’ in psychology to enhancing examination success in schools: The potential contribution of NLP

The strengths and weaknesses of Neuro-Linguistic Programming (NLP) are described with reference to its origins, previous research and comments from critics and supporters. A case is made for this allegedly theoretical approach to provide the kind of outcomes focused intervention that psychology and psychologists can offer to schools. In particular, NLP includes a range of techniques that can be “given away” to teachers and students faced with examination pressures. The implication of such techniques with sixth form (Year 13) students in one secondary school in the South West of England is described and evaluated in terms of student comments on their helpfulness. The case is made for NLP as empowering some students to overcome exam anxiety and other related difficulties. A cyclical eight stage model is proposed for the application of NLP which is considered to offer the most likely effective learning outcomes.
