物件導向軟體之架構(Object-Oriented Software Construction)探討

Aspect] is a simple and practical aspect-oriented extension to Java With just a few new constructs, AspectJ provides support for modular implementation of a range of crosscutting concerns. In AspectJ's dynamic join point model, join points are well-defined points in the execution of the program; pointcuts are collections of join points; advice are special method-like constructs that can be attached to pointcuts; and aspects are modular units of crosscutting implementation, comprising pointcuts, advice, and ordinary Java member declarations. AspectJ code is compiled into standard Java bytecode. Simple extensions to existing Java development environments make it possible to browse the crosscutting structure of aspects in the same kind of way as one browses the inheritance structure of classes. Several examples show that AspectJ is powerful, and that programs written using it are easy to understand.

Computational thinking (CT) uses concepts that are essential to computing and information science to solve problems, design and evaluate complex systems, and understand human reasoning and behavior...

Changing a Generation’s Way of Thinking: Teaching Computational Thinking Through Programming:

The issue of building a Process Support System Environment (PSSE), or a family of PSEE, to make them interoperate or to use them to pilot applications or services requires new solutions; there is almost no hope for a single system to address correctly all the issues.

An Approach and Framework for Extensible Process Support System

After several years of teaching programming using an active learning approach, we present our Interactive Learning Objects (ILOs) as one of the components that reinforce our pedagogical model, by supporting the generation of high-level programming skills. In this paper, we suggest a multi-dimension taxonomy for ILOs and present the experimentation developed to evaluate the impact of these objects within our CS courses

Developing programming skills by using interactive learning objects

Enterprise models are created for documenting and communicating the structure and state of Business and Information Technologies elements of an enterprise. After models are completed, they are mainly used to support analysis. Model analysis is an activity typically based on human skills and due to the size and complexity of the models, this process can be complicated and omissions or miscalculations are very likely. This situation has fostered the research of automated analysis methods, for supporting analysts in enterprise analysis processes. By reviewing the literature, we found several analysis methods; nevertheless, they are based on specific situations and different metamodels; then, some analysis methods might not be applicable to all enterprise models. This paper presents the work of compilation (literature review), classification, structuring, and characterization of automated analysis methods for enterprise models, expressing them in a standardized modeling language. In addition, we have implemented the analysis methods in our modeling tool.

Cupi2 is a project that promotes an integral solution to problems in teaching/learning programming using a large and structured courseware, and a student-centered pedagogical model (Villalobos and Casallas 2006a; Villalobos et al. 2009a, b; Jimenez and Villalobos 2010). As a cornerstone of Cupi2, we use incremental projects intended to motivate students, and to develop high-level programming skills throughout their learning. A critical factor of these projects is that they are specially designed so that students are engaged in activities that complete a scaffold of a complete program. However, both the scaffolds and the activities needed to complete these incomplete programs must be arranged carefully by instructors in order to stress the adequate contents for students, and at the same time, to help those students acquire programming skills effectively. Jointly, scaffold versions need to comply with high quality standards, representing a high time consuming activity for instructors, and therefore, increased costs for institutions. In this paper, we describe the way we overcome these challenges using a software factory that supports the projects' design in a scalable way.

Nous etudions le probleme de la composition par coordination, dans lequel un groupe de composants de domaines distincts doivent travailler ensemble pour realiser une application. Sachant que toute connexion directe entre deux composants de deux domaines differents engendre des problemes d'evolution, nous avons explore la coordination comme une facon de composer. Nous avons caracterise le probleme de la coordination entre domaines, et montre les modeles de conteneurs comme une solution rudimentaire a ce probleme. Nous avons etudie le monde de la coordination, et nous avons introduit la "federation", comme une architecture logicielle qui permet de structurer les applications comme un ensemble de composants qui cooperent pour atteindre un but commun. Nous avons defini l'univers commun (les relations entre les composants de domaines distincts) et les contrats de coordination (la materialisation des regles de jeu), comme les structures de base d'une federation
