| dc.description.abstract | Novice programmers often find learning programming difficult. They suffer from various misconceptions and difficulties in understanding the subject. The overall experience with programming can be negative for many students. They may feel isolated in the programming environment and think that programming is difficult for them. Many schools use automated grading tools to process student work and provide them with early feedback. Web-CAT, an open-source software system that is widely used by many universities, is an example of such an automated grading tool. We have developed a Virtual Teaching Assistant for Web-CAT, called Maria, who can support the students to help alleviate some of the negative emotions towards programming. We have used an animated pedagogical agent as the virtual assistant as certain characteristics of the agent can help with the students' perception about the virtual teaching assistant. Often, students have a fixed mindset about programming. But it is easy to master programming with practice. To promote a growth mindset, Maria also provides feedback recognizing the effort of the student in addition to the performance-oriented feedback of the students' programs. Maria can also provide motivating or encouraging comments to continue working on the assignment to get a good score. Maria can also provide information about the various errors displayed in student feedback. | en |
| dc.description.abstractgeneral | Beginners often find learning computer programming difficult. They may suffer from various misconceptions and difficulties in understanding the subject. Also, there can be a negative experience surrounding programming for many students. They may feel isolated in the programming environment and think that programming is difficult for them. Many schools use automated software tools to grade student programs and provide them with early feedback. Web-CAT, a software system that is widely used by many universities, is an example of such an automated grading tool. We have developed a Virtual Teaching Assistant to reside within Web-CAT, called Maria, who can support the students to help alleviate some of the negative emotions towards programming. We have used an animated human-like character, known as pedagogical agent, for Maria as it is widely use in pedagogy to help students. Often, students think programming is an innate skill and it is difficult to acquire. But it is easy to master programming with practice. To encourage students to continue working, Maria also provides feedback recognizing the effort that the student has put in towards completing the programming assignment or project. In certain cases, Maria can also provide motivating or encouraging comments to the students to help them continue working on the assignment. Maria can also provide explanation about the various programming errors that students encounter during their submission to Web-CAT. | en |
