Integrating program and algorithm visualisation for learning data structure implementation

EGYPTIAN INFORMATICS JOURNAL 2019年第3期20卷 193-204页

作者： Nathasya, Rossevine Artha Karnalim, Oscar Ayub, Mewati Maranatha Christian Univ Fac Informat Technol Prof Drg Surya Sumantri St 65 Bandung 40164 West Java Indonesia

Algorithm visualisation (AV) tool is commonly used to learn data structures. However, since that tool does not address technical details, some students may not know how to implement the data structures. This paper integrates the AV tool with program visualisation (PV) tool to help the students understanding the data structures' implementation. The integration (which is implemented as a tool named DS-PITON) works similarly as a PV tool except that the data structures are visualised with the AV tool. Through quasi experiments, it can be stated that DS-PITON helps students to get better assessment score and to complete their assessment faster (even though the impact on completion time can work in reverse on slow-paced students). Further, according to a questionnaire survey, the students believe that DS-PITON helps them learning data structure materials.

This paper presents an experimental evaluation of a program visualisation tool. Computer science students in an introductory object oriented programming course in Java were asked to respond to a series of questions regarding concepts common to the writing and debugging of code at a novice level. Statistical analysis of data collected from this experiment revealed that a diagrammatic representation can significantly improve the novice understanding of program code.

SPECIFICATION SCHEME FOR THE VISUALIZATION OF DATA-STRUCTURES

引用

SOFTWARE ENGINEERING JOURNAL 1994年第3期9卷 127-133页

作者： LU, XB STETTER, F UNIV MANNHEIM LEHRSTUHL PRAKT INFORMAT 1D-68131 MANNHEIMGERMANY

The paper describes a general principle for program visualisation, based on the concept of structure models. We propose a specification scheme that can be used to implement the general principle without requiring a change of the program code. Two aspects of the scheme are discussed in detail;the specification of critical entities and their graphical representations. Its use is illustrated by means of a specification for the visualisation of a program which calculates the convex hull of a finite set of points.

Virtue: Performance visualization of parallel and distributed applications

引用

COMPUTER 1999年第12期32卷 44-+页

High-speed, wide-area networks have made it both possible and desirable to interconnect geographically distributed lections of scientific data, remote scientific instruments, and high-performance computer systems. Historically, performance analysis has focused on monolithic applications executing on large, stand-alone, parallel systems. In such a domain, measurement, postmortem analysis, and code optimization suffice to eliminate performance bottlenecks and optimize applications. Distributed visualization, data mining, and analysis tools allow scientists to collaboratively analyze and understand complex phenomena. Likewise, real-time performance measurement and immersive performance display systems-that is, systems providing large stereoscopic displays of complex data-enable collaborating groups to interact with executing software, tuning its behavior to meet research and performance goals. To satisfy these demands, the authors designed Virtue, a prototype system that integrates collaborative, immersive performance visualization with real-time performance measurement and adaptive control of applications on computational grids. These tools enable physically distributed users to explore and steer the behavior of complex software in real time and to analyze and optimize distributed application dynamics.

The role of graphics in parallel program development

Graphical visualisation plays an important role in parallel program development. Researchers have proposed and developed many visualisation tools that assist the development of parallel programs. A number of graph formalisms or notations have been used to visualise various aspects of parallel programs and their executions. This paper attempts to classify and compare these graph formalisms and notations which provide different information at different stages of parallel program development. (C) 1999 Academic Press.

A survey of external representations employed in object-oriented programming environments

This document presents an overview of the program visualisations additional to the program code provided by some of the most popular object-oriented programming environments to support tasks involving program comprehension. These representations were compared in terms of the programming aspects they highlight and of their information modality. Those with common characteristics according to these criteria were identified. Finally, a brief analysis of these common representations in terms of Green's Cognitive Dimensions is presented. Two questions arising from this survey are (a) whether representations additional to the code should be redundant and highlight similar information. to the main notation or be complementary and highlight different programming aspects and (b) which factors might increase the cognitive difficulty of co-ordinating these additional representations and the program code. More theoretical knowledge about the way these additional representations influence the comprehension of computer programs seems to be needed. (C) 2003 Elsevier Ltd. All rights reserved.

program visualisation can help make an algorithm understandable. program visualisation is especially challenging in the area of parallel computations where many processors are executing simultaneously Algorithms for parallel machines take advantage of the simultaneous activity of processors to perform operations very quickly?: As a result, these algorithms can be difficult to understand In this paper we describe a visualisation tool developed specifically for explaining algorithms written for single-instruction, multiple-data (SIMD) computers called torus computers. This tool helps its users to visualise the patterns of activities of the processors in the process of a computation.

The authors' experiences with visualization and debugging of parallel virtual machine (PVM) applications and two of the tools they have devised to facilitate these tasks are described. One of the tools is a graphical monitoring package called Xab that can visually display PVM activities inside an application running across a network. The other is a graphical programming environment called Hence, which helps the user write, compile, execute, and trace heterogeneous distributed programs. The authors discuss their early work, the present research, and the future directions of these experimental projects

Pedagogical algorithm visualization systems produce graphical representations that aim to assist learners in understanding the dynamic behavior of computer algorithms. In order to foster active learning, educators have explored algorithm visualization systems that empower learners to construct their own visualizations of algorithms tinder study. Notably, these systems support a similar development model in which coding the algorithm is temporally distinct from viewing and interacting with the resulting visualization. To explore the benefits of narrowing the gap between coding an algorithm and viewing its visualization, we have implemented "What You See Is What You Code, " a novel, "radically dynamic" development model to facilitate learner-constructed algorithm visualizations. In this model, the line of algorithm code currently being edited is reevaluated on every edit, leading to the dynamic update of an accompanying visualizalion of the algorithm. Analysis of usability studies involving introductory computer science students suggests that the immediacy of the model's feedback can help novices to quickly identify and correct programming errors, and ultimately to understand their code's execution.

Model transformations are an important part of Model Driven Engineering (MDE). To generate a transformation with current MDE approaches, users are required to specify (or provide) complex meta-models and then engage in quite low-level coding in textual transformation scripting languages. This paper introduces a new approach to visualising source and target models that allows specifiers of complex data transformations to use the resultant visual notations for specifying transformations by example using drag and drop. We demonstrate the applicability of our new approach by an example case study.
