“…Cross et al explored the use of an integrated debugger as a tool to aid the understanding of novice Java programming students in CS1 [16]. Then they developed a tool called jGRASP [17,18,19]. jGRASP is an Integrated Development Environment (IDE) that supports the visualization of data structure.…”

Many researchers have proposed program visualization tools for memory management. Examples include stateof-the-art tools for C languages such as SeeC and Python Tutor (PT). However, three problems hinder the use of these and other tools: capability (P1), installability (P2), and usability (P3). (P1) Tools do not fully support dynamic memory allocation or File Input / Output (I/O) and Standard Input. (P2) Novice programmers often have difficulty installing SeeC due to its dependence on Clang and setting up an offline environment that uses PT. (P3) Revisualization of the modified source code in SeeC requires several steps. To alleviate these issues, we propose a new visualization tool called PlayVisualizerC.js (PVC.js). PVC.js, which is designed for novice C language programmers to provide solutions (S1-3) for P1-3. S1 offers complete support for dynamic memory allocation, standard I/O, and file I/O. S2 involves installation in a user web browser. This system is composed of JavaScript programs, including C language execution functions. S3 reduces the steps required for revisualization. To evaluate PVC.js, we conducted two experiments. The first experiment found that students using PVC solved a set of four programming tasks on average 1.7-times faster and with 19% more correct answers than those using SeeC. The second experiment found that PVC.js has a visualization performance equivalent to PT, and that PVC.js is more effective than existing general debugging tools for novices to understand programs in cases where the values of important variables change and the control flow is complicated.

In order to avoid the subjectivity and limitation of advancement degree of difficulty evaluating method based on lists, a visualizing method which applies the visualization technology in advancement degree of difficulty computing process is proposed. This method takes the improved technology readiness level assessing result of the technology to be assessed as the input of the visualizing process, and visualizes the readiness status of the technology to a two-dimension coordinate graph. The area which denotes the advancement degree of difficulty of the technology developing from one readiness level to a higher readiness level is shown in the coordinate graph. A computing formula is established to get the advancement degree of difficulty of the technology. The experimental results show that the proposed visualizing method can get the difficulty degree of the technology developing from one readiness level to another readiness level objectively and accurately.
