This is a general purpose system supporting the provision of student programming courses, and performing all the courseware assessment and administration related to a given course.

This will give a good picture of the user view of the software. We will then describe more details the marking metrics and their implementation, and the effects (some of them unexpected) that the system has had on the student learning process.","PeriodicalId":349974,"journal":{"name":"ACM-SE 33","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129483598","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aristotle's front end consists of parsers that gather control flow, local dataflow and symbol table information for procedural language programs. We implemented a parser for C by incorporating analysis routines into the GNU C parser; a C++ parser is being implemented using similar techniques. Aristotle tools use the data provided by the parsers to perform a variety of tasks, such as dataflow and control dependence analysis, dataflow testing, graph construction and graph viewing. Most of Aristotle's components function on single procedures and entire programs. Parsers and tools use database handler routines to store information in, and retrieve it from, a central database. A user interface provides interactive menu-driven access to tools, and users can view results textually or graphically. Many tools can also be invoked directly from applications programs, which facilitates the development of new tools. To assist with system development and maintenance, we are also creating support tools for managing bug and test suite databases.","PeriodicalId":349974,"journal":{"name":"ACM-SE 33","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131715021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

With the recent development of computer networks and the widespread deployment of networked workstations, automating the group writing process for geographically distributed users has become feasible. In this paper, a software package which supports distributed, real-time, multimedia collaborative work, known as the Distributed Collaborative Writing Aid (DCWA), is described. The DCWA has five major parts but the emphasis of this paper is on the DCWA's distributed database, which is crucial to making the entire system work together both logically and consistently. The database is a specialized, distributed system based on the client-server model implemented in C++ running under 4.3BSD Unix and provides dynamic management capabilities unique for a multimedia collaborative working environment.","PeriodicalId":349974,"journal":{"name":"ACM-SE 33","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133858795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Functions that are special reversible injections (1-to-1 functions) lead here to two subclass subconstructions in which functions control the values. We show by means of such functions that a subset or superset of the values of a class can become, in effect, its subclass. The constructions are exemplified in but not limited to C++. Taxonomic hierarchies based on is-a links [2] are usually presented as the purpose of subclasses [1]. A view of subclasses related to subtypes was presented in [3]. But one of our constructions is based neither on an is-a link nor on subtypes; it suggests there are alternative bases for hierarchies.","PeriodicalId":349974,"journal":{"name":"ACM-SE 33","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1995-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128769446","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The students at each site were set up so that they could \"talk\" with their counterparts across the country, trade files with them, and actually teach each other some different aspects of the Internet. One interesting facet of this protocol is that one site taught its students \"A, B and C,\" while the other site taught its students \"X, Y and Z.\" The students then use the technology that they learned to teach their counterparts across the country.
