Individual based models (IBMs) are up-to-date tools both in research and educational areas. Here we introduce an IBM built on NetLogo platform that simulates a top-down trophic cascade controlled by the pressure exerted by two model predators (web-building spiders and ground runner spiders) on a model pest (the olive fruit fly) within a…

Teachers around the world have started teaching programming at the K-9 level, some due to the formal introduction of programming in the national curriculum, others without such pressure and on their own initiative. In this study, we attempted to understand which skills -- both CT-related and general -- are developed among pupils in the process of…

This article draws on a one-semester online programming course to determine the relationships between the types of feedback that students received and their programming performances. An explorative study was designed including both quantitative and qualitative data. Participants were 15 second-year students enrolled at an Information Technology…

Scratch is a tool for initial learning of programming, but also for creating educational and entertainment content, making mathematical and scientific projects, simulating and visualizing experiments. This paper examines the effectiveness of Scratch's application in mathematics, in the study of basic geometric shapes. The analysis has shown that…

While demand for computer science and information technology skills grows, the proportion of women entering computer science (CS) fields has declined. One critical juncture is the transition from high school to college. In our study, we examined factors predicting college persistence in computer science- and technology-related majors from data…

This paper highlights the year-one (pilot) findings of a three-year project on emerging technologies where students engaged in computer modeling, 3D printing, flight simulation, and drones during summer camps and afterschool programs in rural and urban districts. The pilot was iterative as different interventions were field-tested in specific…

Computers are problem-solving tools at heart. Without an operating system though, they would be rendered useless. Most computer users are unaware of the inherent capabilities of the bare OS and the problems it can solve for them. This comes naturally in an era of commercialized solutions in the form of apps and software packages. However, gaining…

Although postgraduate students are required to be self-directed, this is not always the case. The aims of this study were twofold. Firstly, we investigated whether the use of problem-based projects supported students in implementing different cryptography algorithms as part of a group assignment. Secondly, we determined to which extent the use of…

The purpose of this research is to investigate the short and long-term effects of using GUI-oriented visual Blocks-Based Programming languages (BBL) as a 2nd tier tool when teaching programming to prospective K12 ICT teachers. In a mixed-method approach, the effect on academic success as well as the impact on professional opinions and preferences…

It is observed that teacher candidates receiving education in the department of Computer and Instructional Technologies Education are not able to gain enough experience and knowledge in "Programming Languages" lesson. The goal of this study is to analyse the effects of web 2.0 technologies usage in programming languages lesson on the…

Today's children need learning opportunities from cradle to career that build the knowledge and skills necessary to thrive in our interconnected and constantly changing world. This means putting 21st century skills, including creativity, innovation, critical thinking, and problem solving, at the center of learning, both in and out of school. As…

Mobile application development is currently an important component of CS/IS education. Because of the rapid rate of change in the mobile application field, there are many websites that provide instructional material in tutorial format, but it is difficult to find a textbook that includes mobile application programming assignments and exercises.…

This research shows the power of powerful metaphors in a language or linguistic perspective. It aimed at examining the important factors like reproduction of metaphors according to the theme of contestation, its duration, use of electronic media and problems associated with their forms, class and syntactic structures in a linguistic perspective.…

We study the automatic identification of educational items worthy of content authors' attention. Based on the results of such analysis, content authors can revise and improve the content of learning environments. We provide an overview of item properties relevant to this task, including difficulty and complexity measures, item discrimination, and…

The current quantitative study, a naturalistic field experiment, was conducted in a public primary school in Soweto, Johannesburg, with the objective to examine how children's achievement on four assessments at the beginning of Grade R, namely their numeracy, their mathematics-specific vocabulary, their executive functions, and their logical…
