How Learning Logic Programming Affects Recursion Comprehension

Recursion is a central concept in computer science, yet it is difficult for beginners to comprehend. Israeli high-school students learn recursion in the framework of a special modular program in computer science (Gal-Ezer & Harel, 1999). Some of them are introduced to the concept of recursion in two different paradigms: the procedural programming paradigm and the logic programming (LP) paradigm. Here we discuss the implication of first learning recursion in LP on the students’ understanding of the concept. The declarative approach for teaching recursion in logic programming seems to enhance students’ recursion comprehension. We found that students who learned recursion in LP before learning it in a procedural paradigm differed, in terms of their mental models of recursion, from those who were acquainted with recursion in procedural programming only. More of the LP students possessed an adequate model of recursion as a process than did the non-LP students. Moreover, the LP students also attained a unique conception of recursion as a tool for knowledge representation.

Organizing and Managing Software Engineering Team Projects

Industrial software development today requires a fundamental education in computer science as well as the ability to work productively and collaboratively in a team environment. Employers will therefore favor graduates who have mastered computer science and software engineering concepts and can apply them while developing a software system. To produce computer science graduates possessing the skills necessary to succeed in the workplace, team‐oriented software engineering courses with real projects (and with real clients) are increasingly emphasized. It is, however, difficult to successfully present a software engineering course that covers software engineering concepts and offers opportunities to apply them during a project in a team environment. The difficulties lie in project selection, team formation, team and project organization, process management, and, finally, grading. The objective of this article is to discuss these difficulties and provide suggestions for alleviating or avoiding them.     

How Students Attempt to Reduce Abstraction in the Learning of Mathematics and in the Learning of Computer Science

This article focuses on ion and ways in which students cope with abstraction. The article has two goals: first, it illustrates how the theme of reducing abstraction (Hazzan, 1999) is useful for analyzing students' thinking about abstract concepts in mathematics and in computer science; second, it demonstrates how theories based on mathematics education research can be applied to analyzing students' understanding of computer science concepts. The main section of the article analyzes the understanding of concepts from four fields – abstract algebra, computability, data structures and differential equations – through the lens of reducing abstraction. The analysis shows that a wide range of cognitive phenomena can be explained by one theoretical framework.

Two for One: Squeezing Human-Computer Interaction and Software Engineering into a Core Computer Science Course

The final report of the Joint Task Force on Computing Curricula (CC2001) suggests that an updated computer science curricula must reflect the broadening nature of our discipline. Two areas that are included in the CC2001 are software engineering (SE) and human-computer interaction (HCI). While the first inclination might be to incorporate HCI concepts into a traditional SE course, we propose a different approach. This paper outlines a project-oriented HCI course in which we are able to emphasize some SE notions in the context of HCI concepts. Our course is also a maturation class for our students because they are exposed to a number of non-programming computer science activities, including project specification, software and interface design, user testing, prototyping and use of guidelines. We include an overview of course content that illustrates our approach. We also describe our coverage of specific CC2001 knowledge units and provide some feedback data for our course.     

函数编程技术在计算机数学教学中的应用探讨

计算机数学,又称离散数学,是计算机学科的重要专业基础课程。在实际教学中发现,计算机科学专业的学生对该课程感兴趣的不多,多数畏惧其概念多、理论强且抽象。利用一种函数式程序设计语言(Haskell)辅助学生进行计算机数学中相关概念理解及其实际编程实验,主要针对课程教学中代数系统(如群)知识点,通过群定义及其性质验证实验来介绍函数编程技术,可以帮助计算机专业学生更好地学习理解计算机数学课程,并能充分调动其学习积极性和主动性,还可培养学生接受新知识的能力。     

Implementation of Real‐World Experiential Learning in a Food Science Course Using a Food Industry‐Integrated Approach

Success skills have been ranked as the most important core competency for new food science professionals to have by food science graduates and their employers. It is imperative that food science instructors promote active learning in food science courses through experiential learning activities to enhance student success skills such as oral and written communication, critical thinking, problem solving, and team work. The aim of this study was to incorporate “real‐world” experiential learning into a food product development course. Undergraduate students enrolled in a food product development course worked on a semester‐long product development case study developed by the Instructor of the course and the Manager from ACH Food Companies, Inc. The case study was presented to students in the form of a product development competition. Students were placed into groups and given the task to develop a cake mix with specified parameters. At the end of the semester, student groups participated in a case study competition to showcase their product concepts. Each student group gave a PowerPoint presentation and was evaluated using selected criteria. Students rated the course overall as being very good. Students perceived the case study to be beneficial and informative regarding employer (ACH's) expectations. Students recommended that the Instructor minimize restrictions/specifications for product concepts and increase the quantity of course/laboratory meetings per week. This approach will continue to be used and further evaluated as an approach to incorporate active learning and provide food science undergraduates with a sense of employer expectations.     

Networks of law encoding diagrams for understanding science

Understanding science involves the mastery of complex networks of concepts. To design effective computer based systems for learning science it is essential to adequately characterize the nature of those conceptual networks, so that clear and appropriate instructional goals can be defined and fed into the design process. This paper considers a novel class of representations for science instruction — Law Encoding Diagrams (LEDs) — and describes the nature of scientific understanding based on these representations. A framework of four classes of schemas has been proposed to characterizes problem solving and learning with LEDs. How the framework encompasses complex networks of concepts is discussed and the implications for the design of computer based learning environments based on LEDs are considered.

The (Non)Importance of a Programming Language in a Software Engineering Course

Our catchy title is intended to be controversial, provoking thought upon the impact (or lack of any) that a programming language has on the curriculum for a software engineering course. Our view on the subject is from both directions, as indicated by the title. As educators, we argue that the language issues are secondary to the fundamental concern of understanding software engineering concepts, specifically object‐oriented concepts. However, we appreciate that expertise in a widely accepted object‐oriented language may be essential towards the more practical aspect of building a critical mass of software engineers versed in object‐oriented techniques. This reflects upon the maturing nature of computer science and engineering as a science, which is evolving its fundamental principles, while at the same time recognizing its impact as an engineering discipline sensitive to practical applications. The evolution of our primary software engineering course, CS250 Introduction to Software Engineering, has been influenced by our own reflections on the state of software engineering in the 1990s, industrial requirements for expertise by our graduates, and the needs of accreditation. We present the internal and external factors that have guided our course design. This process reflects our own experiences in academia and industry. We present this process as a representative model of a sound approach, but make no claims that it is the optimal approach.

A Microcomputer Interfacing Course for Computer Science Majors

This paper describes a microcomputer interfacing course for computer science students. Students build simple logic circuits to interface a microcomputer with real‐world devices, such as stepper motor and digital displays, and program the computer to monitor and control these devices. Programs are written in Pascal and assembly language. The emphasis is placed on applications rather than on theory. This course is especially designed for computer science students who are proficient in software programming but have little or no experience in electronics. The experiments described here have been developed on the Apple ft microcomputer, but they can be easily adapted to other microcomputers.     

Need Assessment of Computer Science and Engineering Graduates

This case study considered the syllabus of the first and second year studies in computer science. The aim of the study was to reveal which topics covered in the syllabi were really needed during the following years of study or in working life. The program that was assessed in the study was a Masters program in computer science and engineering at a university of technology in Finland. The necessity of different subjects for the advanced studies (years 3?–?5) and for working life was assessed using four content analyses: (a) the course catalog of the institution where this study was carried out, (b) employment reports that were attached to the applications for internship credits, (c) masters theses, and (d) job advertisements in a newspaper. The results of the study imply that the necessity of physics for the advanced study and work was very low compared to the extent to which it was studied. On the other hand, the necessity for mathematics was moderate, and it had remained quite steady during the period 1989?–?2002. The most necessary computer science topic was programming. Also telecommunications and networking was needed often, whereas theoretical computer science was needed quite rarely.
