This article reports on difficulties related to the concepts of inheritance and polymorphism, expressed by a group of 22 in-service CS teachers with an experience with the procedural paradigm, as they coped with a course on OOP. Our findings are based on the analysis of tests, questionnaires that the teachers completed in the course, as well as on…

From the point of view of functional programming, a computational process to solve a problem is described as a mathematical function taking some arguments (corresponding to the data of the problem) and returning as a result its solution. Turtle Graphics can be used to describe the movements of a virtual turtle, which leaves a trail along his path…

Video and computer games have become an important area of study in the field of education. Games have been designed to teach mathematics, physics, raise social awareness, teach history and geography, and train soldiers in the military. Recent work has created computer games for teaching computer programming and understanding basic algorithms. …

Because high school graduates are many colleges' primary target population, information on high school students' performance and sociodemographic characteristics becomes important for the recruitment process. This article introduces an HTML application (referred to here as the High School Profile) that arranges high school information and makes…

A verbal and e-mail survey was conducted of 30 senior high teachers in Alberta who teach computer programming courses in the Career and Technology Studies curriculum, in order to ascertain what courses at the intermediate and advanced levels were being offered, what programming languages were being used, why teachers selected the particular…

This paper proposes an approach to introducing object-oriented concepts to high school computer science students using the Object-Oriented Turing (OOT) language. Students can learn about basic object-oriented (OO) principles such as classes and inheritance by using and expanding a collection of classes that draw pictures like circles and happy…

A study of 89 computer programming students in two instructional groups found that those using Visual Basic (VB) mastered programming design concepts as well as those using traditional BASIC. Concludes that VB is an excellent choice for a first programming course (high school or university) emphasizing sequence, selection, iteration, variables,…

The intent of this project was to improve test and programming scores of 9th through 12th grade students enrolled in the Practical Computer Skills: Logo course in a north central Florida high school. An implementation program that demonstrated teacher-designed graphical computer language Logo programs, utilized multimedia techniques, and used…
