“…For example, Ilves et al [45] used radar charts to support self-regulated learning and found that the lowest-performing students can benefit from this visualization. Ishizue et al [46] presented a program visualization tool called PlayVisualiz-erC for novice C language programmers to learn the concept of memory management. Auvinen et al [47] found that visual achievement badges can also have a positive impact on students' online study practice.…”

Learning is challenging, especially in the self-paced online learning environment. Not all the students start online learning with the skills to manage their learning plans, balance work-study, and find learning resources. Therefore, as an online educational institution, providing learner support services are essential to improving learning outcomes and student satisfaction. The existing studies have analyzed the impact of learner support services on student satisfaction, learning outcomes, and course retention. However, the relationship between these services and student engagement in the long-term learning process has not been fully examined. To address this issue, this paper investigates students' usage of two online learner support (OLS) services and their impact on student engagement. We examined four student groups categorized by their usage of two OLS services and analyzed student engagement with an online course using learning log data and visual analytics techniques. The findings indicate that the use of services and how many times the services are used are highly relevant to the pattern and level of student engagement, which suggests that the use of OLS services can be added to the indicators that reflect student learning status.

“…Pythontutor, proposed by PhilipGuo visualizes the code by displaying the data structures used [3]. Another visualization tool called PlayVisualizerC (PVC) that dynamically visualizes the code in terms of memory allocations has been proposed by Ryosuke et al in [27]. Visualization tools have been developed to help students learn programming, debugging and explore various possible ways of writing programs.…”

“…Visualizing statements on the go will help novice programmers in identifying and rectifying the mistakes if any, at the early stages of the code, as a result reducing the debugging efforts. Also, PointerViz displays primitive visualization of pointers, which is identical to the way budding programmers draw on paper, unlike PVC [27] which displays memory locations and internal details. This primitive representation can help novice programmers relate better to their interpretations.…”

Pointers are considered as one of the key concepts in learning programming and are extensively used for implementing several data structures. They lay the foundation for handling dynamic aspects of a program, increase execution speed and handle data types with more efficiency. This makes it critical for budding programmers to be well versed with using pointers. However, most of the novice programmers find it difficult and tricky to understand concepts such as address allocations, pointers referring pointers and data structures containing pointers. Hence, drawing the physical structure and flow of pointers is considered to be a common learning practice to gain better clarity and avoid confusion when learning pointers. But, it is time consuming and tedious to draw the flow of pointers on paper while programming. To help programmers understand these variations in pointers, we propose PointerViz as a Google Chrome extension that displays the pictorial representation of selected code with pointers. We conducted a preliminary survey with 40 students from various universities and 83% of the users reported positive experience with the plugin.

“…Many instructors believe that online coding tools reduce the dropout rates in introductory programming classes [20], and these tools have been shown to be useful in helping students master syntax of programming languages [13]. There are claims that coding tools increase the self-confidence of students in Computer Science [4,15], while visualization is useful for novices and programmers in general [11,14]. It is widely accepted in Computer Science education research that automating processes, such as grading, can save resources and also seems to overall positively impact academic performance [7,21].…”

Approaches for Coordinating eTextbooks, Online Programming Practice, Automated Grading, and More into One Course

We share approaches for coordinating the use of many online educational tools within a CS2 course, including an eTextbook, automated grading system, programming practice website, diagramming tool, and debugger. These work with other commonly used tools such as a response system, forum, version control system, and our learning management system. We describe a number of approaches to deal with the potential negative effects of adopting so many tools. To improve student success we scaffold tool use by staging the addition of tools and by introducing individual tools in phases, we test tool assignments before student use, and we adapt tool use based on student feedback and performance. We streamline course management by consulting mentors who have used the tools before, starting small with room to grow, and choosing tools that simplify student account and grade management across multiple tools.
