{"title":"Effectiveness of a computer-based feedback system for writing","authors":"K. Anandam, Ed Eisel, L. Kotler","doi":"10.1145/503838.503880","DOIUrl":"https://doi.org/10.1145/503838.503880","url":null,"abstract":"Miami-Dade Community College has developed a computer-based instructional management program that assists faculty in providing individualized feedback to their students about writing and keeps meticulous records of students' writing and faculty's feedback activities. The computer system that was used for this program is RSVP (Response System with Variable Prescriptions). The term \"prescriptions\" in the name RSVP stands for individualized feedback statements that are intended to reinforce students for the correctness of their writing, assist them in correcting their errors, and/or expand their understanding of fundamental concepts. Based on designs determined by the faculty, these statements are combined and printed as a cohesive letter of communication from faculty to individual students.The RSVP Feedback Program for Individualized Analysis of Writing was field tested in two community colleges by four faculty. Each participant used the program for one section of a course and not for another at the freshman composition level. The faculty were free to select their own textbooks, teaching methods, and grading policies. The program functioned as a support system.At the end of our experimental study with pre- and post-test measures, we found that the students in the RSVP groups scored significantly higher than those in the non-RSVP groups on the objective test but not on the essay test. We also found in a general attitude questionnaire that the students in all four groups felt more positive toward their classes on writing than toward writing itself, and the students receiving RSVP feedback felt slightly more positive toward writing than did the students in the non-RSVP groups. Finally, we found in an RSVP questionnaire that the students in all the RSVP groups felt quite positive about the feedback program; in an RSVP questionnaire for faculty, we found that two of the four teachers expressed positive reactions toward the program, one expressed negative reactions, and one expressed mixed reactions.As a support system for various configurations of teaching strategies and curriculum materials, the RSVP Feedback Program was intended to give individualized feedback in definable areas of writing such as punctuation, grammar, and diction. On the other hand, holistic scoring--the method used to evaluate the essay tests--spans areas that the totality of instructional activities is intended to cover, although not necessarily addressed by the RSVP Feedback Program. While there was a significant difference between the RSVP and non-RSVP groups on the objective test that focused on the areas covered by the RSVP Feedback Program, there was no significant difference in the holistic scores that represented the \"whole\" writing. In other words, the RSVP Feedback Program accomplished what it was expected to do, nothing more and nothing less.","PeriodicalId":431590,"journal":{"name":"ACM-SE 18","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125848000","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}

Particularly in the liberal arts disciplines, there is a prevalent point of view that the effectiveness of instruction will be improved more by setting higher admissions standards and failing more students than by deliberately tailoring instruction to prespecified behavioral outcomes, and providing students with a means of identifying and remediating skill areas that impede subsequent instruction. In this presentation, a recently developed set of procedures are described which have shown to be effective in involving typically disinterested instructors in a meaningful instructional design process, These procedures use a testing center and computer management as the catalyst to the design process. This presentation provides an overview of how involvement of instructor is accomplished, and a summary of results obtained through ensuing instructional development activities.","PeriodicalId":431590,"journal":{"name":"ACM-SE 18","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129438122","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}

{"title":"An online system for Medicaid file maintenance","authors":"Elizabeth Davis, Gail Brownlee","doi":"10.1145/503838.503843","DOIUrl":"https://doi.org/10.1145/503838.503843","url":null,"abstract":"Since the volume of data generated by a social service program has become so great, an automated system is required to provide the security, efficiency , and reliability essential to meeting the needs of the people. Increasingly complex governmental regulations further the usefulness of automation. A computer system must be able to handle large masses of data efficiently, detect abuse of the system and probable user error, and keep current , accurate information about all aspects of the social service program. An online system for the maintenance of information is ideally suited to handling these conditions. South Carolina has developed a Medicaid Management Information System (MMIS) that effectively meets all these requirements. It may seem unusual for a division of Clemson University to be designing and implementing a Medi-caid system for the South Carolina Department of Social Services (DSS). The charter of the Division of Information Systems Development of Clemson University (DISD), however, is to handle state-supported contracts. DSS does not have the staff to develop or produce a certifiable Medicaid system of such a large scale, so South Carolina's MMIS is a cooperative effort. The Medicaid program works on the state level in helping to meet medical costs for the needy.

Generally, several images, related by a common geographic location, are needed to provide end users, that is, persons involved in cartographic, land management, and other geographic applications, with adequate information. The reasons for maintaining related geographic images in a common data bank are much the same as those for storing any related data in such a form. The need to access several images at one time dictates the need for centralized storage. Also, an image data base allows independence of image processing functions from image data while at the same time reducing the overhead associated with maintaining multiple files.","PeriodicalId":431590,"journal":{"name":"ACM-SE 18","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127816469","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}

{"title":"Mapping problems within heterogeneous distributed data base systems","authors":"E. Lisboa","doi":"10.1145/503838.503877","DOIUrl":"https://doi.org/10.1145/503838.503877","url":null,"abstract":"Supporting heterogeneous database systems in a distributed database environment requires the translation between different forms of data representation and of data manipulation while transmitting data within the network. A generally accepted approach to this translation is to define a standard database system interface (data model and data manipulation language) and to build a global schema of the distributed data. If there is a need to move data from one network node to another, the request for data is first translated into the standard interface, and then converted into the destination database interface to be evaluated. The general problem of translations between different database interfaces is known as the \"mapping problem\". In this paper, we consider the mapping problem in a heterogeneous distributed database environment.First, two components of database mappings are considered: the data mapping that expresses the source data structure's elements in terms of the target data structure's elements, and the operator mapping that translates the source operators into the corresponding target operators using as reference the data mapping.Four different types of mapping are identified according to the relationship between the source and the target data strucutes. First, the trivial mapping where both the source and the target data structure express exactly the same data structure using the same data model. In this case, the data mapping, as well as the operator mapping, is totally expressed by an identity function. Second, the schema mapping where the source and target data structure differ, even though the underlying data model is the same. Third, the model mapping where the data structures expressed in both schemas are exactly the same, but are described using different data models. Finally, the total mapping occurs when both source and target data models and data structures differ. Each of these four mapping cases presents its own inherent difficulties that are analyzed through the paper.Then mappings are considered within Distributed Data Base Systems. We propose an architectural arrangement that localizes total and schema mappings between the user and the standard interfaces, and limits mappings between the standard and local interfaces to the trivial and model mapping cases. Several advantages result from this arrangement (which does not lessen the mapping flexibility between user and local interfaces). The mappings between the standard and local interfaces are certified feasible and in their simplest form, the design and evaluation of the standard schema is facilitated and the operator decomposition and scheduling are rendered independent of schema mappings.Lastly, the paper presents the architectural framework and the mapping capabilities of a heterogeneous distributed database system being implemented at the University of Southwestern Louisiana.","PeriodicalId":431590,"journal":{"name":"ACM-SE 18","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1980-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115692454","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}
