However, prior studies have been conducted at a single institution on a small or medium scale, without the possibility of data re-use. read more read lessĪbstract: Automatically observing and recording the programming behaviour of novices is an established computing education research technique. The two main contributions of this research are: (i) the breadth and depth of its investigation into the concepts held by novices studying OOP, and (ii). Nevertheless, at the end of the courses, the students understood the basic principles of OOP. In total, 58 conceptions and difficulties were identified. object, instantiation and constructors, simple vs. The findings were divided into four primary categories: class vs. The research used a constructivist qualitative research methodology using observations and field notes, audio and video recordings, and an analysis of artifacts such as homework assignments. Our approach to teaching featured: objects-first, teaching composed classes relatively early, deferring the teaching of main methods, and focusing on class structure before algorithms. During two academic years, we taught OOP to high school students, using Java and BlueJ. This has led to a modular design that permits both internal and external extensibility.read more read lessĪbstract: This article describes research on the learning of object-oriented programming (OOP) by novices. Moreover, we have developed an intermediate language that is used to decouple the interpretation of the program from its visualization. In this paper we explain the model for the system and introduce the features of the user interface and visualization engine. In this process, the user interface and visualization has evolved to better suit the targeted audience, which in the case of Jeliot 3, is novice programmers.
The development process of Jeliot has been research-oriented, meaning that all the different versions have had their own research agenda rising from the design of the previous version and their empirical evaluations. The key feature of Jeliot is the fully or semi-automatic visualization of the data and control flows. This textbook is printed in four-color to aid pedagogy and reader learning.Ībstract: We present a program visualization tool called Jeliot 3 that is designed to aid novice students to learn procedural and object oriented programming.
#BLUEJ MAIN METHOD CODE#
Throughout, the emphasis is on developing a practical approach to programming, with students encouraged to add code to existing programs rather than working with an intimidating sheet of blank paper. This book takes an objects first approach to teaching the traditionally difficult concepts of objects in a manipulative visual form. A large numberof different, interesting projects are used to provide variety and avoid the monotony of a running problem. Language features are introduced as a response to the problems to be solved.
#BLUEJ MAIN METHOD SOFTWARE#
Unlike traditional textbooks, the chapters are not ordered by language features but by software development concepts. BlueJ's clear visualization of classes and objects means that readers can immediately appreciate the differences between them, and gain a much better understanding of the nature of an object than theywould from simply reading source code. Its close integration with the BlueJdevelopment environment allows this book tofocus on key aspects of object-oriented software development from day one. TL DR: Objects First with Java: A Practical Introduction Using BlueJ, 5e as discussed by the authors is the only introductory programming textbook that uses the BlueJ integrated development environment (IDE) to teach introductory and object-oriented programming principles using Java.Ībstract: Objects First with Java: A Practical Introduction Using BlueJ, 5e, is ideal for introductory courses in Java/Introduction to Programming and Object-Oriented Programming and for beginning programmers.This is the only introductory programming textbook that uses the BlueJ integrated development environment (IDE) to teach introductory and object-oriented programming principles using Java.
