A computer supported memory aid for copying prescription parameters into medical equipment based on linguistic phrases

Manually operated medical equipment, including drug infusion pumps, are often subject to input errors. Human operators copy data from a prescription into the relevant form field on the equipment panels. This process is error prone and time consuming. A computer supported memory aid is proposed where the user remembers phrases instead of value sequences. The proposed strategy speeds up the task of setting up medical equipment while reducing the chances of human errors

Instructional strategies and tactics for the design of introductory computer programming courses in high school

This article offers an examination of instructional strategies and tactics for the design of introductory computer programming courses in high school. We distinguish the Expert, Spiral and Reading approach as groups of instructional strategies that mainly differ in their general design plan to control students' processing load. In order, they emphasize topdown program design, incremental learning, and program modification and amplification. In contrast, tactics are specific design plans that prescribe methods to reach desired learning outcomes under given circumstances. Based on ACT* (Anderson, 1983) and relevant research, we distinguish between declarative and procedural instruction and present six tactics which can be used both to design courses and to evaluate strategies. Three tactics for declarative instruction involve concrete computer models, programming plans and design diagrams; three tactics for procedural instruction involve worked-out examples, practice of basic cognitive skills and task variation. In our evaluation of groups of instructional strategies, the Reading approach has been found to be superior to the Expert and Spiral approaches

Expert Programming Knowledge: a Schema-Based Approach

The topic of this chapter is the role of expert programming knowledge in the understanding activity. In the "schema-based approach", the role of semantic structures is emphasized whereas, in the "control-flow approach", the role of syntactic structures is emphasized. Data which support schema-based models of understanding are presented. Data which are more consistent with the "control-flow approach" allow to discuss the limits of the former kind of models

Expert memory: A comparison of four theories

This paper compares four current theories of expertise with respect to chess players’ memory: Chase and Simon’s (1973) chunking theory, Holding’s (1985) SEEK theory, Ericsson and Kintsch’s (1995) long-term working memory theory, and Gobet and Simon’s (1996b) template theory. The empirical areas showing the largest discriminative power include recall of random and distorted positions, recall with very short presentation times, and interference studies. Contrary to recurrent criticisms in the literature, it is shown that the chunking theory is consistent with most of the data. However, the best performance in accounting for the empirical evidence is obtained by the template theory. The theory, which unifies low-level aspects of cognition, such as chunks, with high-level aspects, such as schematic knowledge and planning, proposes that chunks are accessed through a discrimination net, where simple perceptual features are tested, and that they can evolve into more complex data structures (templates) specific to classes of positions. Implications for the study of expertise in general include the need for detailed process models of expert behavior and the need to use empirical data spanning the traditional boundaries of perception, memory, and problem solving

Factors affecting the success of non-majors in learning to program

The introductory programming course is difficult for many university students, especially students who have little prior exposure to programming. Many factors affecting student success have been identified, but there is still a dearth of knowledge about how key factors combine to affect course outcomes. In this study we develop and empirically test a model integrating three factors of importance in learning to program: previous programming experience, perceived self-efficacy, and knowledge organization. The participants were non-majors. The findings showed that perceived self-efficacy increased significantly during a semester course. Previous experience affected perceived self-efficacy but not knowledge organization. Both perceived self-efficacy and knowledge organization had an effect on the course grade, as well as on success in a specific programming task, debugging. The results on self-efficacy also suggested that the participants were overconfident about their programming capabilities. The contribution of this paper is the identification of the joint effects of an important set of factors for programming success by non-majors

Programlama Öğretimi için Bir Model Önerisi: Yedi Adımda Programlama

There are a number of studies in the literature revealing that programming instruction has positive effects on development of different cognitive skills. However, there are scarcely any studies suggesting pedagogical approaches to how programming should be done. Therefore, this study focused on how to do programming instruction that target developing students’ cognitive skills. In this study, it was aimed to suggest a model for teaching in order to develop various cognitive skills of students. Within the scope of the study, a programming instruction model was created, and it was called Programming in Seven Steps (PSS) model. As research design, special case study was used from qualitative research methods. The research team consisted of two groups: design team (1 faculty member from the department of Computer Education and Intructional Technologies (CEIT), 2 master’s degree students, and 2 PhD students) and a Design Evaluation Team (DET) (10 IT and Software teachers who work in secondary schools affiliated to the Ministry of National Education) in the process of constructing the PSS model. During the research, the documents and interviews with the design evaluation team were analyzed with the purpose of determining the steps of the PSS model. The study elaborates the process followed to create the model, the features of the proposed model, and interviews with the design evaluation team. This article details the overall path to designing of the model, the features of the model, and DET interviews. It is aimed that the model introduced in this study will become a guide for educators who want to teach programming at secondary school level.Alanyazında programlama öğretiminin pek çok bilişsel beceriye olumlu etkilerini ortaya koyan çalışmalar yer almaktadır.

Cognition Matters: Enduring Questions in Cognitive IS Research

We explore the history of cognitive research in information systems (IS) across three major research streams in which cognitive processes are of paramount importance: developing software, decision support, and human-computer interaction. Through our historical analysis, we identify “enduring questions” in each area. The enduring questions motivated long-standing areas of inquiry within a particular research stream. These questions, while perhaps unapparent to the authors cited, become evident when one adopts an historical perspective. While research in all three areas was influenced by changes in technologies, research techniques, and the contexts of use, these enduring questions remain fundamental to our understanding of how to develop, reason with, and interact with IS. In synthesizing common themes across the three streams, we draw out four cognitive qualities of information technology: interactivity, fit, cooperativity, and affordances. Together these cognitive qualities reflect IT’s ability to influence cognitive processes and ultimately task performance. Extrapolating from our historical analysis and looking at the operation of these cognitive qualities in concert, we envisage a bright future for cognitive research in IS: a future in which the study of cognition in IS extends beyond the individual to consider cognition distributed across teams, communities and systems, and a future involving the study of rich and dynamic social and organizational contexts in which the interplay between cognition, emotion, and attitudes provides a deeper explanation of behavior with IS

Essential competencies of exceptional professional software engineers

Department Head: Rodney R. Oldehoeft.1991 Fall.Includes bibliographical references (pages 141-144).This dissertation presents a differential study of exceptional and non-exceptional professional software engineers in the work environment. The first phase of the study reports an in-depth review of 20 engineers. The study reports biographical data, Myers-Briggs Type Indicator test results, and Critical Incident Interview data for 10 exceptional and 10 non-exceptional subjects. Phase 1 concludes with a description of 38 essential competencies of software engineers. Phase 2 of this study surveys 129 engineers. Phase 2 reports biographical data for the sample and concludes that the only simple demographic predictor of performance is years of experience in software. This variable is able to correctly classify 63% of the cases studied. Phase 2 also has the participants complete a Q-Sort of the 38 competencies identified in Phase 1. Nine of these competencies are differentially related to engineer performance. A10 variable Canonical Discriminant Function is derived which is capable of correctly classifying 81% of the cases studied. This function consists of three biographical variables and seven competencies. The competencies related to Personal Attributes and Interpersonal Skills are identified as the most significant factors contributing to performance differences
