“…To help a student write a complex code, the detailed information for the source code implementation is described in the test code. Previously, we confirmed the effectiveness of this informative test code approach in studying the three object-oriented programming concepts for Java [7]. It is expected that a student will learn how to use the concepts by writing a source code which can pass the test code.…”

To enhance Java programming educations, we have developed a Java Programming Learning Assistant System (JPLAS). In JPLAS, the code writing problem asks a student to implement a source code that passes the given test code on JUnit, where the details of the implementation are described in the test code. Previously, we confirmed the effectiveness of this informative test code approach in studying three object-oriented programming concepts for Java. In this paper, we present its application to studying Java Collections Framework (JCF). JCF enables us to handle a group of objects by offering appropriate libraries, which is expected to be mastered by the students. For evaluations, we generated five informative test codes for JCF, and asked 19 students from Japan, Myanmar, China, and Indonesia to implement the source codes. Then, all of them completed the source codes passing the test codes, while certain students did not use the expected JCF library functions.

A Web-based Java Programming Learning Assistant System (JPLAS) has been proposed to assist Java programming educations in universities. In the code writing problem, the correctness of an answer code from a student is verified by running the test code on JUnit. Besides, their quality should be measured using the metrics to assess them. The currently using plugin could only be measured on eclipse for offline answering in JPLAS. To calculate the metrics and implement in web-based JPLAS, there are several equations that have been reported. In this paper, we find the proper equations to calculate the metrics that provide the same results as from Eclipse plugin. The application results for 45 source codes showed that the adopted metrics equations provide the same results as the plugin.

“…The hints describe the byte size of each data type with the word size that is necessary to calculate the increase of the memory address, and the memory addresses of the first two elements in the array variables, so that students can answer the question on them. printf ("arr1 [4] is %c \n", arr1 [4]); printf ("arr2 [3] is %d \n", arr2 [3]); printf ("arr3 [2] is %f \n", arr3 [2]); printf ("arr4 [1] is %f \n", arr4 [1]);…”

and understand their behaviors to be familiar to the programming paradigm. Unfortunately, effective tools to support independent code reading study at home have not been well designed. Heretofore, we have proposed the value trace problem (VTP) for Java programming. A VTP instance consists of one source code, several questions, and the correct answers to them. Each question asks the value of a critical variable or output message in the source code. The correctness of any student answer is checked instantly by string matching at the answer interface for self-study. In this paper, we present the value trace problem (VTP) for code reading self-study of C programming. 42 VTP instances are generated using simple C source codes on basic grammar concepts and fundamental data structures & algorithms in textbooks and websites. In addition, for hard instances on pointer and algorithms, the devices of hints, multiple choice questions, and references are provided to improve their solution performances. For evaluations, we requested 49 undergraduate students in Japan, China, and Myanmar to independently solve them at home. Their average correct answer rate reached 94.29%, where our devices for hard instances improved it by 33.26%. Thus, the effectiveness of our proposal is confirmed in motivating self-study of C programming to novice students.
