Introduction CURRENTLY, with no longer barrier by space and time, a web-based educational system plays the important rule to support students and teachers. There are many advantages for information sharing and collaboration between students and teachers in a course because students can study their interested courses though a web-based class so as to enhance their knowledge at any time and any place and teachers can easily manage their online classes and monitor student’s performance as well. Also, web-based educational systems can incorporate various kinds of multi- * Kunyanuth Kularbphettong. Tel.: +662-160-1159; fax: +662-160-1159.

Intelligent tutoring systems (ITS) are computer programs that are widely implemented so as to support and customized classes automatically without intervention from a human teacher (Psotka, & Sharon Mutter, 1988). During the rapid grown of the web technology, Web Intelligence is a promising channel of Artificial Intelligent issues and there are many ITS applications which are developed and applied to use in various educational level. Also, Type-2 fuzzy logic was applied to develop a webbased intelligent tutoring system for teaching in a basic control course (Francesco, Pignato, Piccolo, Nicolosi, Schembri and Lipoma, 2010). Moreover, a web based learning system, ActiveMath, was adapted in Mathematics to enhance long distance learning (Melis & Siekmann, 2004). And Mastery learning is termed by Benjamin Bloom. It was based on differentiated and individualized practices, progress monitoring, assessment, and feedback to improve the process of classroom practice (Bloom, Mastery learning¸ 1971; Zimmerman & Dibenedetto, 2008). Therefore, the purpose of this research aims to develop an Adaptive Web-Based Intelligent Tutoring System using Mastery Learning Technique to support students in learning computer programming courses in case of Suan Sunandha Rajabhat University. Rule based approach and student information were conducted in this project to classify and suggest student’s learning. Moreover, it is also beneficial to apply this model to different courses. The remainder of this paper is organized as follows. Section 2 presents related works and research methodologies used in this work. Section 3 we describe the system architecture based on the purposed model and section 4 shows the results of this experiment. Finally, the conclusion and future research are presented in section 5. 2. Related Works and Research Methodologies In this section, we illustrate related works and specified methodologies used in this project. 2.1. Related Works A literature search shows that most of the related researchers have developed Adaptive Web-Based Intelligent Tutoring Systems to support learners in different courses by following this: According to Butz, Hua, and Maguire (2006) a Web-based intelligent tutoring system, called BITS, was implemented by using a Bayesian network approach to support students in learning computer programming at the University of Regina. E-TCL (an Expert tutoring system for teaching computer programming languages) can support teachers so as to cooperate computer programming language courses together and use agent approach in the project (El-Khouly, Far, and Koono, 2000). Sykes and Franek (2003) presented “JavaTM Intelligent Tutoring System” (JITS) which was designed for students in their first programming course in JavaTM at the College and University level. There are many models of a webbased intelligent tutoring system which are purposed and implemented. The most of related research works concentrate on student’s learning knowledge than enhance and analyze student’s cognition. Hence, this research was adapted mastery technique with this system. 2.2. Research Methodologies Intelligent Tutoring Systems (ITS) are computer programs to solve learning problem, monitor, coach, and consult learners (Sleeman & Brown, 1982). ITSs include mainly four principal components: the domain model, the student model, the tutoring model and the user interface model. The domain model is based on ACT-R theory which assumes the fundamental theory of distinction between declarative and procedural knowledge. This model is tried to solve a problem and acts as a source of expert knowledge of ITS. The student model is the main component of ITSs and it consists of the cognitive, motivational and other affective states that effect to performance of student’s learning (Pavli, Brawner, Olney & Mitrovic, 2013). The tutor model cooperates between the domain and student model to mange tutoring strategies and actions. And the user interface model acts to integrate information of three components: knowledge about patterns of interpretation and action within dialogues; domain knowledge for communicating content and knowledge needed for communicating intent. Mastery learning was introduced in 1960’s and 1970’s and it consists of three significant characteristics: the use of tutor; the unit-perfection requirement 688 Kunyanuth Kularbphettong et al. / Procedia - Social and Behavioral Sciences 191 (2015) 686 – 691 and the self-paced feature (Green, 2000). Mastery learning can enhance learner’s proficiency and encourage positive attitudes in learning (Guskey, 2007) According to Jon Bergmann and Sams, the mastery model is used technology to pace the student’s learning (Bergmann & Sams, 2012). In the mastery learning technique, teacher defined the objectives of student’s learning with carefully and plans the learning strategies for each student and student need to demonstrate their understand the purpose and criteria of learning and regulations. If they achieve the referenced objectives, they can move on next works. Otherwise, they need to learn and complete a topic until they succeed. Therefore, teachers need to monitor the progress of learners by collecting student’s learning data so as to plan next instruction. Mastery learning is a pattern of teaching so that teachers can be used and adapted in their class. To assess in mastery learning technique, cognitive diagnostic, formative and summative assessment are used to evaluate in the mastery learning classroom. Cognitive diagnostic assessment is evaluated to find the causes and weaknesses of students and formative assessment is used to evaluate during the learning process. And summative assessment is evaluated at the end of the course. 3. System Architecture The architecture of the system consists of 4 parts: the User Interface part, the Student part, the Tutor part and the intelligent part, as shown in Fig.1. Fig. 1 the system architecture In the user interface part is consisted of two main functions: providing information to users and displaying diagnostic information. It receives input from the user and sends the information to the related parts for processing. The Student part, student can register his/her profile, such as personnel information, email address, username and password, and etc., and he/she is assigned to take pre-test so as to initialize the student profile. According to Chakraborty, Roy and Basu (2010), this project was used two aspects to measure the cognitive state of a student: Comprehension–ability and Problem-solving skill. The Tutor part allows teachers to set and determine teaching objectives and strategies. Besides, it allows teachers to indicate pre-test, post-test and tutorial. Pre-test includes the groups of questions to assess prerequisite student’s knowledge. Post-test is evaluated the effectiveness of student’s knowledge after learning related tutorial. The intelligent part interacts with students and teachers in pedagogy view and teaching strategies. It determines student’s individual characteristics and learning styles based on the result score of pre-test. After that the system evaluates his/her comprehensive by the result score of post-test. And Fig 2 was shown the system framework. Kunyanuth Kularbphettong et al. / Procedia - Social and Behavioral Sciences 191 (2015) 686 – 691 689 Fig. 2 Framework of the system 4. Experimental Results In this section, experimental results were separated to 2 parts: developing the Adaptive Web-Based Intelligent Tutoring System and evaluating the performance and satisfaction of the application. 4.1. Developing the Adaptive Web-Based Intelligent Tutoring System The system was evaluated by freshman students in Java Programming course at Suan Sunandha Rajabhat University. This study took places in 2 classes with 45 students and 22 students. The experimental results showed that the project can help student learning and reduce time consuming study. To evaluate the preliminary prototype system, questionnaires were used to measure user satisfaction with system usability by teacher and student in the following issues: the usability of user interface, the comprehensive of the system’s content, and user satisfaction in overall system. The results were satisfactory as followed: Means for teacher and students were 4.15 and 4.23, and standard deviation for specialists and users were 0.645 and 0.714 respectively. 4.2. Developing the Adaptive Web-Based Intelligent Tutoring System To test and evaluate the qualities of the system, Black box Testing and Questionnaires by teachers and students were used to test this application. Black Box testing was assessed in the error of the project as following: functional requirement test, Function test, Usability test, Performance test and Security test. The ability of this application was evaluated by Functional Requirement test in needs of the users and Functional test was used to evaluate the accuracy of the system. Usability test was tested the suitability of the system. Performance test was used the processing speed of the system. Finally, Security test was evaluated the security of the system and Table 1 and Fig 3 were shown the results of Black box testing. 690 Kunyanuth Kularbphettong et al. / Procedia - Social and Behavioral Sciences 191 (2015) 686 – 691 TABLE 1 The results of Black box testing Teachers SD ݔҧ 1.Function Requirement Test 3.71 0.665 2.
