Python’s use in education has grown rapidly due to its elegantly simple syntax. Though often viewed as a “scripting language,” Python is a fully object-oriented language with an extremely consistent object model and a rich set of builtin classes. We are finishing our second year using Python as the language for an object-oriented CS1 course. Based on these experiences, we discuss aspects of Pyt...

A major obstacle to sharing computable clinical knowledge is the lack of a common language for specifying expressions and criteria. Such a language could be used to specify decision criteria, formulae, and constraints on data and action. Al-though the Arden Syntax addresses this problem for clinical rules, its generalization to HL7's object-oriented data model is limited. The GELLO Expression l...

Goals form a declarative description of the desired end result of (part of) an orchestration. A goal-oriented orchestration language is an orchestration language in which these goals are part of the language. The advantage of using goals explicitly in the language is added flexibility in handling failures. In this paper, we investigate how goal-oriented mechanisms for handling failures compare ...

Language learning is often viewed as a task focused on the acquisition of linguistic skills, disregarding cultural context in which language spoken. This approach to leads ineffective communication and misunderstandings that arise due differences. The article discusses challenges BIPA students West Sumatra face when attempting develop their communicative abilities cross-cultural understanding. ...

Natural language as the main media form of the domain information plays an important role in object-oriented domain analysis. However, students are not well guided and supported in how to work with natural language. This paper presents the observation on the difficulties in teaching object-oriented analysis, from the perspective of natural language. Based on the results gained from the case stu...

This paper introduces a framework for the rapid prototyping of object oriented programming languages. This framework is based on specifying the semantics of a language using term rewriting and a continuation-based representation of control. The notation used, called K, has been developed specifically for programming languages to overcome limitations in more general rewriting notation, and provi...

Central to the spirit of reflective teaching is the ability to focus critically on one’s own beliefs, cognitions, and concerns. Numerous proposals have been developed for implementing reflective practices in pre-service teacher education contexts with the aim of producing highly competent reflective teachers. However, it is imperative to identify the candidates’ beliefs and knowledge base befor...

This paper documents KOOL, a dynamic, object-oriented language designed using the K framework. The KOOL language includes many features available in mainstream object-oriented languages, including such features as runtime type inspection and exceptions. Since the language is currently changing, this should be seen as a snapshot of the language at this point in time.
