“…Actually, JPLAS offers the grammar-concept understanding problem (GUP) [3], the mistake correction problem (MCP) [4], the value trace problem (VTP) [5], the element fill-in blank problem (EFP) [6], the code completion problem (CCP) [7], the phrase fill-in-blank problem (PFP) [8], and the code writing problem (CWP) [9]. In any instance of these problems, the correctness of an answer from a student is automatically checked in JPLAS.…”

Nowadays, Java is one of the world’s most used object-oriented programming languages for its dependability and portability. To assist the self-studies of novice students, we have developed the Java programming learning assistance system (JPLAS). JPLAS offers several types of exercise problems for different difficulties, including the grammar-concept understanding problem (GUP), the mistake correction problem (MCP), the element fill-in-blank problem (EFP), and the phrase fill-in-blank problem (PFP), where a question asks to answer the corresponding keyword or phrase in the given source code. Unfortunately, some students cannot solve them well as the difficulty level is ascending. In this paper, to help such students, we propose a hint function that will show the first or more characters of each correct answer word in the answer interface on a web browser for JPLAS, when requested. The use of this function by a student can be traced by a teacher to analyze the performance and problem difficulty. For evaluations, we generated three instances for GUP, MCP, EFP, and PFP respectively, and assigned them to junior students taking the Java programming course in Okayama University, Japan. Their answer results found that the proposal is effective in helping students solve exercise problems in JPLAS, but the thinking time needs to be adjusted for PFP.

“…Recently, as a new problem type for the code writing study of C programming by novice students, we have proposed and studied the phrase fill-in-blank problem (PFP) [7]. In a PFP instance, the source code contains several blanks of phrases or sets of multiple elements.…”

In a lot of universities across the world, C programming is taught to novice students in the first programming course. To assist their self-studies, we have developed C programming learning assistant system (CPLAS) that offers various programming problems with different learning goals where any answer from a student is automatically marked at the system. In this paper, we studied the phrase fill-in-blank problem (PFP) in CPLAS for learning basic C programming. A PFP instance gives a source code where several key phrases (set of elements) are blanked and requests to fill in them by a student. The correctness of answers is checked through string matching with the original ones. For evaluations, we generated 22 PFP instances for learning basic grammar topics and logic functions and assigned them with previous 15 instances for recursive functions to 21 students in Okayama University. The results confirmed the correctness of the generated instances and found the weakness of students in C programming study.
