Starting from scratch: experimenting with computer science in Flemish secondary education

In the Flemish secondary education curriculum, as in many countries and regions, computer science currently only gets an extremely limited coverage. Recently, in Flanders (and elsewhere), it has been proposed to change this, and try-outs are undertaken, both in and outside of schools. In this paper, we discuss some of those efforts, and in particular take a closer look at the preliminary results of one experiment involving different approaches to programming in grade 8. These experiments indicate that many students from secondary schools would welcome a more extensive treatment of computer science. Planning and implementing such a treatment, however, raises a number of issues, from which in this paper, we formulate a handful as calls for action for the computer science education research community

Challenging the Computational Metaphor: Implications for How We Think

This paper explores the role of the traditional computational metaphor in our thinking as computer scientists, its influence on epistemological styles, and its implications for our understanding of cognition. It proposes to replace the conventional metaphor--a sequence of steps--with the notion of a community of interacting entities, and examines the ramifications of such a shift on these various ways in which we think

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

Effects of using educational robotics at the elementary school level

The purpose of this research was to learn more about the uses and benefits of educational robotics in an elementary school curriculum

ROBOSIM: An intelligent simulator for robotic systems

The purpose of this paper is to present an update of an intelligent robotics simulator package, ROBOSIM, first introduced at Technology 2000 in 1990. ROBOSIM is used for three-dimensional geometrical modeling of robot manipulators and various objects in their workspace, and for the simulation of action sequences performed by the manipulators. Geometric modeling of robot manipulators has an expanding area of interest because it can aid the design and usage of robots in a number of ways, including: design and testing of manipulators, robot action planning, on-line control of robot manipulators, telerobotic user interface, and training and education. NASA developed ROBOSIM between 1985-88 to facilitate the development of robotics, and used the package to develop robotics for welding, coating, and space operations. ROBOSIM has been further developed for academic use by its co-developer Vanderbilt University, and has been in both classroom and laboratory environments for teaching complex robotic concepts. Plans are being formulated to make ROBOSIM available to all U.S. engineering/engineering technology schools (over three hundred total with an estimated 10,000+ users per year)

Exploring the development of mental rotation and computational skills in elementary students through educational robotics

Interest in educational robotics has increased over the last decade. Through various approaches, robots are being used in the teaching and learning of different subjects at distinct education levels. The present study investigates the effects of an educational robotic intervention on the mental rotation and computational thinking assessment in a 3rd grade classroom. To this end, we carried out a quasi-experimental study involving 24 third-grade students. From an embodied approach, we have designed a two-hour intervention providing students with a physical environment to perform tangible programming on Bee-bot. The results revealed that this educational robotic proposal aimed at map-reading tasks leads to statistically significant gains in computational thinking. Moreover, students who followed the Bee-bot-based intervention achieved greater CT level compared to students following a traditional instruction approach, after controlling student's prior level. No conclusive results were found in relation to mental rotation

Exploring the Development of Pre-Service Teachers\u27 Knowledge and Attitudes Toward Integrating Computational Thinking and Robotics into the Classroom

This paper presents an introductory computational thinking (CT) module that can be implemented into teacher education curricula. The researchers examined how the integration of CT and robotics instruction into an undergraduate instructional technology course influenced pre-service teachers\u27 understanding of CT and robotics and their attitudes towards adopting these tools in their future classrooms. The online module was developed as a result of a collaboration between computer science and education faculty from two universities. A total of 93 students participated in the study. The course was delivered during the spring, summer, and fall semesters of 2020 via distance learning at a large public university located in Florida. Data for this study were collected using a pre-and post-test survey that was created with Qualtrics software. This paper describes how the CT and robotics concepts were taught and examines the influence of the instruction on participants\u27 knowledge and attitudes of CT and robotics and their integration into the classroom

Utilization of Robotics in Higher Education

The use of technology in the classroom has evolved from the most primitive to the widespread use of personal computers. One of the trends in technological advancements to enter the classroom is the use of robotics. The relationship between robotics and education spans many years. This paper details Papert’s Constructionism theory defining learning as being more effective when students are “constructing” or “doing” activities that are personally meaningful. Research includes assessment of experiences of this method of teaching Information Technology through robotics at such institutions as West Point, Reykjavik University and University of South Florida. Based on the experiences reported at the various institutions, authors conclude with recommendations to Bryant College as the college launches an integration of the utilization of robotic components into the Information Technology curriculum to more effectively introduce students to Information Technology concepts
