Design, development and assessment of the Java Intelligent Tutoring System

The "Java Intelligent Tutoring System" (JITS) research project focused on designing, constructing, and determining the effectiveness of an Intelligent Tutoring System for beginner Java programming students at the postsecondary level. The participants in this research were students in the School of Applied Computing and Engineering Sciences at Sheridan College. This research involved consistently gathering input from students and instructors using JITS as it developed. The cyclic process involving designing, developing, testing, and refinement was used for the construction of JITS to ensure that it adequately meets the needs of students and instructors. The second objective in this dissertation determined the effectiveness of learning within this environment. The main findings indicate that JITS is a richly interactive ITS that engages students on Java programming problems. JITS is equipped with a sophisticated personalized feedback mechanism that models and supports each student in his/her learning style. The assessment component involved 2 main quantitative experiments to determine the effectiveness of JITS in terms of student performance. In both experiments it was determined that a statistically significant difference was achieved between the control group and the experimental group (i.e., JITS group). The main effect for Test (i.e., pre- and postiest), F( l , 35) == 119.43,p < .001, was qualified by a Test by Group interaction, F( l , 35) == 4.98,p < .05, and a Test by Time interaction, F( l , 35) == 43.82, p < .001. Similar findings were found for the second experiment; Test by Group interaction revealed F( 1 , 92) == 5.36, p < .025. In both experiments the JITS groups outperformed the corresponding control groups at posttest.

A study of students' metacognitive beliefs about foreign language study and their impact on learning

This article reports on an investigation into the language learning beliefs of students of French in England, aged 16 to 18. It focuses on qualitative data from two groups of learners (10 in total). While both groups had broadly similar levels of achievement in French in terns of examination success, they dffered greatly in the self-image they had of themselves as language learners, with one group displaying low levels of self-eficacy beliefs regarding the possibility of future success. The implica tions of such beliefs for students' levels of motivation and persistence are discussed, together with their possible causes. The article concludes by suggesting changes in classroom practice that might help students develop a more positive image of them selves as language learners.

Identifying language needs of ESL students in a Canadian university based intensive English language program

This study investigated the needs of adult ESL learners intending to pursue higher education in Canada. Its chief purpose was to enable educators and administrators to design ESL programs that would prepare students to function at optimal levels in academic and social settings during their university studies. The study adopted a mixed research method that was predominantly qualitative in its orientation and narrative in its implementation. It focused on an Intensive English Language Program (IELP) offered at an Ontario university. Using a holistic approach, the study sought to represent the various perspectives of all the participants in the program: the students, the instructors, and the administrators. Analysis of both qualitative and quantitative data gathered from 17 students, 6 instructors, and 1 administrator in the IELP showed that to a large extent the academic needs ofESL learners in the IELP were generally not being met. Most notably, the study found that learners were not receiving sufficient training in speaking and listening skills, a factor that contributed to their sense of insecurity and lack of confidence in their ability to communicate successfully in academic and social settings. The study also revealed that the solutions to many of the problems it identified lay not in the classroom but in the way the ESL program was structured administratively. One major recommendation to come out of the study is that programs like the IELP should be restructured so as to give them greater flexibility in meeting individual needs. While the study labored under certain limitations and did not achieve all of its goals, it did succeed in creating awareness ofthe problems and in establishing a methodological approach that can serve as a framework within which future research may be conducted in this somewhat neglected area.
