algorithm visualization (AV) can be analyzed and evaluated through three properties: the symbol system, the interactivity, and the didactic structure. While the relationship between various symbol systems have been researched and efforts to increase learner and AV interaction are being made, the importance and potential of the didactic structure of AV is yet to be explored. In view of this deficiency, this paper proposes Categories of algorithm Learning Objective (CALO) as a pedagogical framework for designing and structuring AV. Based on seven non-hierarchical learning objectives commonly found in CS education, CALO provides a conceptual framework for a more learner-centered design, as well as a shared language for educators, learners and designers for communication and evaluation.

Although many algorithm visualization (AV) tools are available online, most of them are not effective in helping students to learn algorithm and data structures. The reasons for this may be the poor design consideration of the tools to fulfill the learners' needs in terms of pedagogy, usability, and accessibility. This paper reports a work-in-progress research project at Athabasca University on developing an effective algorithm visualization tool for online learning. We analyze the pedagogy, usability, and accessibility goals and their respective features for the online learners and examines how the visualization and user interaction principals can help to achieve these goals in the design process of an effective AV tool. We present a review of the related literature to highlight current and past researches and illustrate the need for better user experience design in AV tools. We then identify the online learners' needs and the context of their activities to design a usable, useful, effective, and pleasurable interactive AV tool. Such a tool can fulfill the pedagogy, usability, and accessibility goals for the online learners.

We report a study on collaborative learning with algorithm visualizations (AV). We have previously confirmed the hypothesis that students' higher engagement has a positive effect on learning outcomes when they learn collaboratively. Thus, in this paper the analysis is targeted on students' collaborative learning process in order to find phenomena that explain the learning improvements. In the video and audio analysis of the learning sessions, we have identified that the amount of collaboration and discussion increase when the level of engagement increases. Furthermore, the groups that used visualizations on higher level of engagement, discussed the learned topic on different levels of abstraction whereas groups that used visualizations on lower levels of engagement tended to concentrate more on only one aspect of the topic. Therefore, one of our conclusions is that the level of engagement indicates, not only the learning performance, but also the amount of on-topic discussions in collaboration. Furthermore, based on previous literature, we claim that the amount and quality of discussions explain the learning performance differences when students use visualizations in collaboration on different levels of engagement.

More collaborative use of visualizations is taking place in the classrooms due to the introduction of pair programming and collaborative learning as teaching and learning methods. This introduces new challenges to the visualization tools, and thus, research and theory to support the development of collaborative visualization tools is needed. We present an empirical study in which the learning outcomes of students were compared when students were learning in collaboration and using materials which contained visualizations on different, engagement levels. Results indicate that the level of engagement has an effect on students learning results although the difference is not statistically significant. Especially students without previous knowledge seem to gain more from using visualizations on higher engagement level.

As people tend to integrate technology more and more in their lives, one of the most evident aspects which has a great impact on their learning methods are the E-learning platforms which provide interactive means to develop new skills in problem-solving topics. The development of an Elearning platform that simplifies the way in which users engage with the information while simultaneously enhancing their level of comprehension is, without a question, the fastest and most effective strategy. Trend, in matter of learning techniques, has also brought new challenges and opportunities to enhance assimilation of information. Thus, during the process of learning, focus has to be actively maintained through a series of stimuli. algorithm visualization blended with Artificial Intelligence is the solution that the paper intends to present as a reaction to the actual inclination.

algorithm visualizations (AVs) have become a popular teaching aid in classes on algorithms and data structures. The AlgoViz Project attempts to provide an online venue for educators, students, developers,researchers, and other AV users. The Project is comprised of two websites. The first, the AlgoViz Portal, provides two major informational resources: an AV catalog that provides both descriptive and evaluative metadata of indexed visualizations, and an annotated bibliography of research literature. Both resources have over 500 entries and are actively updated by the AV community. The Portal also provides field reports, discussion forums, and other community-building mechanisms. The second website, OpenAlgoViz, is a SourceForge site intended to showcase exemplary AVs, as well as provide logistical and hosting support to AV developers.

This special issue presents extended versions of six papers presented at the 5th Program visualization Workshop (PVW’08). The articles deal with many of the issues relevant to program and algorithm visualization in education. This foreword introduces these issues to better understand the challenges addressed by every article, and their relevance, as well as the articles featured. These issues are evaluation of program and algorithm visualization, integration of visualization and narratives into hypertextbooks, embedding of interactive quizzes into visualizations, and several classes of program visualization.

What you see is what you code: A "live" algorithm development and visualization environment for novice learners

JOURNAL OF VISUAL LANGUAGES AND COMPUTING 2007年第1期18卷 22-47页

Pedagogical algorithm visualization (AV) systems produce graphical representations that aim to assist learners in understanding the dynamic behavior of computer algorithms. In order to foster active learning, computer science educators have developed AV systems that empower learners to construct their own visualizations of algorithms under study. Notably, these systems support a similar development model in which coding an algorithm is temporally distinct from viewing and interacting with the resulting visualization. Given that they are known to have problems both with formulating syntactically correct code, and with understanding how code executes, novice learners would appear likely to benefit from a more "live" development model that narrows the gap between coding an algorithm and viewing its visualization. In order to explore this possibility, we have implemented "What You See Is What You Code," an algorithm development and visualization model geared toward novices first learning to program under the imperative paradigm. In the model, the line of algorithm code currently being edited is reevaluated on every edit, leading to immediate syntactic feedback, along with immediate semantic feedback in the form of an AV. Analysis of usability and field studies involving introductory computer science students suggests that the immediacy of the model's feedback can help novices to quickly identify and correct programming errors, and ultimately to develop semantically correct code.

We present a unifying view of visualization in which comprehensive support for software, algorithm, process and application (including scientific) visualizations is treated as an essential component of the computing environment. We describe our recent work toward making this view a reality: a tool for computer‐assisted design of visualizations and a technique for monitoring a computational process in a non‐invasive fashion.
