Debugging (or troubleshooting) provides a rich context to foster problem-solving. Yet, while we know much about some problems and strategies that novices face in programming on-screen, we know far less about debugging and troubleshooting in the context of physical computing, where coding issues may overlap with materially embedded problems. In…

Many studies have recently focused on the importance of the effective integration of Information and Communication Technology (ICT) tools in science education and the need for science teachers to receive adequate training and support to use them effectively. This paper aims to explore the Albanian science teachers' perceptions and use of ICTs in…

In this study, based on quasi-experimental research, was investigated the effects of teaching Python programming language via Blockly tool, which had hybrid interface, on students' computer programming anxiety, cognitive load level, and achievement. Participants were 90 high school students, 44 of them in experimental group (hybrid interface) and…

Sensor systems have the potential to make abstract science phenomena concrete for K-12 students. Internet of Things (IoT) sensor systems provide a variety of benefits for modern classrooms, creating the opportunity for global data production, orienting learners to the opportunities and drawbacks of distributed sensor and control systems, and…

Tasks for teaching predictive modelling and APIs often require learners to use code-driven tools. Minimal research, however, exists about the design of tasks that support the introduction of high school students and teachers to these new statistical and computational methods. Using a design-based research approach, a web-based task was developed.…

The purpose of this study was to investigate the relationship among Taiwanese high school students' learning style, sense of presence, cognitive load, and affective and cognitive learning outcomes in an immersive virtual reality-based learning environment. This study used a teaching experiment intervention method. Seventy-seven students…

In recent years, massive open online Courses (MOOCs) as an online instruction format have attracted educators' attention in higher education. While there are many news reports and blog entries about MOOCs, evidence-based research is still emerging. Research examining the learners' perspective on taking a MOOC is scarce but very much needed. This…

With the advent of Web 2.0 technology, message transmission has become increasingly convenient, and the rising amount of information has become gradually diverse. A question must be asked of this trend, on whether informal learning resources can be integrated into formal learning knowledge. This study attempts to integrate educational blog…

This paper deals with the design of interactivity in visualization tools. There are several factors that can be used to guide the analysis and design of the interactivity of these tools. One such factor is flow, which is concerned with the duration of interaction with visual representations of information--interaction being the actions performed…

This paper reports on a series of introductory programming workshops, initially targeting female high school students, which utilised Lego Mindstorms robots. Cognitive load theory (CLT) was applied to the instructional design of the workshops, and a controlled experiment was also conducted investigating aspects of the interface. Results indicated…

We present a new and innovative interface that allows the learner's body to move freely in a multimodal learning environment. The Situated Multimedia Arts Learning Laboratory ("SMALLab") uses 3D object tracking, real time graphics, and surround-sound to enhance embodied learning. Our hypothesis is that optimal learning and retention occur when…

The goal of the User-Centered Digital Library Project, conducted by the National Center for Accessible Media (NCAM) at WGBH, was to adapt the Teachers' Domain online digital library to enable teachers and students with disabilities to more readily use the resources in science classrooms. NCAM added accessibility features such as captions and audio…

Standards-based reform efforts are highly dependent on accurate assessment of all students, including those with disabilities. The accuracy of current large-scale assessments is undermined by construct-irrelevant factors including access barriers, a particular problem for students with disabilities. Testing accommodations such as the read-aloud…
