Dessa forma o conhecimento pode ser construído de forma iterativa e coletiva. A utilização da tecnologia tem grande potencial no suporte ao ensino a distância, por exemplo: os quizzes online permitem avaliar uma grande quantidade de pessoas através de perguntas diretas e com respostas curtas. Existem inúmeras ferramentas de construções de quizzes na Web. Contudo elas possuem a desvantagem de não ter uma base de conhecimento formal, permitindo o compartilhamento, manipulação e reuso de conhecimento que estão nos quizzes. Neste ponto o uso de ontologia pode contribuir com compartilhamento, manipulação e reuso de conhecimento em nível de software ou como modelos conceituais de referência. Neste trabalho desenvolveu-se um modelo de ferramenta para construção de quizzes apoiada por uma ontologia lightweight sobre a leishmaniose. Para complementar o uso do modelo foi modelada uma rede bayesiana com o objetivo de regular um assunto de um quiz para um aluno específico. Os resultados encontrados são promissores desde a concepção, regulação e validação de quizzes por um grupo de alunos de medicina.

In this thesis we present the improvements and refinements that we made to the QuizScript system. QuizScript allows users, using simple markup, to quickly and easily generate interactive quizzes, composed of multiple types of questions, and provides immediate feedback to students. It was designed by Christine and Bill Wadge to overcome the tediousness often experienced while creating quizzes using other systems, such as Moodle. However, QuizScript has several shortcomings and their rectification is the focus of this thesis. We remedied these drawbacks by designing and implementing the following: a parser to detect errors; new functionalities; a database to store and retrieve the quizzes; and a dynamic website to host the quizzes, which enables an immediate preview of the quiz. / Graduate / 0984 / yasser83@uvic.ca

The QUIZIT system has been developed to support adaptive and standard testing, along with automatic grading, record keeping, and test administration using the WWW as a delivery vehicle. We have applied QUIZIT in connection with our NSF-supported Education Infrastructure project on Interactive Learning with a Digital Library in Computer Science to help with evaluation in a master's level course as well as a large freshmen level service course. Preliminary testing in these courses has shown us that QUIZIT is a promising supplement to other forms of evaluation in self-paced education. We also conjecture QUIZIT might be a valuable tool in distance learning environment. / Master of Science

This experiment was designed to determine which assessment method: continuous assessment (in the form of daily in-class quizzes), cumulative assessment (in the form of online homework), or project-based learning, best predicts student learning (dependent upon posttest grades) in an undergraduate mathematics course. Participants included 117 university-level undergraduate freshmen enrolled in a course titled "Mathematics for Calculus". Initially, a multiple regression model was formulated to model the relationship between the predictor variables (the continuous assessment, cumulative assessment, and project scores) versus the outcome variable (the posttest scores). However, due to the possibility of multicollinearity present between the cumulative assessment predictor variable and the continuous assessment predictor variable, a stepwise regression model was implemented and caused the cumulative assessment predictor variable to be forced out of the resulting model, based on the results of statistical significance and hypothesis testing. The finalized stepwise regression model included continuous assessment scores and project scores as predictor variables of students' posttest scores with a 99% confidence level. Results indicated that ultimately the continuous assessment scores best predicted students' posttest scores.

A study was conducted to determine the effects of directed discovery-based teaching methods (hands-on learning) and weekly quizzes on short-term learning and long-term retention of course material in an introductory geosciences laboratory course. Assessment of learning was accomplished using percentages of correct responses to questions on two tests, using percentages from the first semester of the study as a baseline to which data from each subsequent semester were compared to determine the effects of the study variable that was introduced. Student evaluations of value, meaning, and enjoyment of the course were also investigated through the use of an essay question at the end of the second test. The study revealed that directed discovery-based methods were successful for the teaching of some subject material, but not for all, and that the method did not necessarily enhance learning of scientific vocabulary. Weekly quizzes resulted in improved learning in all subject areas. Simultaneous use of traditional and directed-discovery teaching methods as well as weekly quizzes is recommended.

Student success in chemistry has been linked to a wide range of factors. Some of these factors are familiar, easily quantified measures; colleges typically rely on factors like high school GPA and measures of aptitude to make admission decisions or set course prerequisites. Success in chemistry courses can be linked to these measures, and math aptitude scores in particular are often used as prerequisites for introductory chemistry courses. However, success in chemistry can also be affected by factors like motivation, peer interactions, sense of belonging, and metacognitive skill. Additionally, outcomes in chemistry and other STEM courses like math and physics have been repeatedly found to be inequitable. In Chapter I, background information relevant to the subsequent chapters will be discussed. In Chapter II, group quizzes were implemented as a collaborative learning tool in a large-lecture format first-semester organic chemistry classroom. Chapter III describes a multifaceted scholarship support program for chemistry, physics, and math majors. This program strove to support traditionally underrepresented groups in chemistry through several components, including a team-building course and mentorship. Heavy emphasis was placed on building a peer support network. In Chapter IV, confidence surveys were implemented to encourage student metacognitive monitoring. Student success and confidence were assessed through three scopes: as they pertained to the overall course, by exam, and by individual topic.

L’objectif de la thèse est de trouver les moyens d’améliorer la réussite en statistiques des étudiants en psychologie, en examinant les effets des feedbacks de comparaison sociale ou temporelle délivrés dans un environnement numérique d'apprentissage, plus particulièrement un exerciseur en ligne. Cet objectif s’appuie sur trois constats. Premièrement, les études qui s’intéressent aux environnements numériques pour l'apprentissage des statistiques montrent qu’une des caractéristiques centrales de ce type d’outil est l’utilisation de feedbacks immédiats, alors même que le type de feedback délivré est rarement questionné. Deuxièmement, la littérature s’est largement intéressée aux feedbacks centrés sur la tâche et assez peu à ceux qui reposent sur des processuspsychosociaux, comme la comparaison sociale ou temporelle. Troisièmement, les effets de ces comparaisons ont très rarement été étudiés en même temps, a fortiori dans le cadre d’exerciseurs en ligne. Le programme derecherches se décompose en deux séries d’études. Les trois premières études examinent les effets des feedbacks de comparaison sociale et temporelle sur les performances en statistiques. Les deux dernières études s'apparentent à des « recherches-action » visant à amener les étudiants à utiliser l’exerciseur en ligne à partir d’interventions pédagogiques réalisées en Travaux Dirigés. Globalement, les résultats ne montrent pas d’effet robuste des feedbacks de comparaison mais confirment le rôle prépondérant du comportement consistantà remettre un travail à plus tard (procrastination) et du niveau initial en mathématiques sur la réussite des étudiants. Les implications de ces résultats sont discutées en tenant compte du contexte écologique danslequel s'inscrivent ces recherches. / The aim of this thesis is to find ways of improving psychology students’ statistics performance, by examining the influence of social or temporal comparison feedback delivered in a web-based training environment. This aim is based on three observations. Firstly, immediate feedback has been shown as a central characteristic of web-based learning environments for statistics, but studies rarely interrogate which kind of feedback is delivered. Secondly, studies generally focus on taskoriented feedback rather than on psychosocial processes such as social and temporalcomparison. Thirdly, these two comparisons have rarely been examined at the same time, a fortiori in web-based training environments. The research program is divided in two sets of studies. The first three studies examine theinfluence of social or temporal comparison feedback on statistics performance. In the last two studies, interventions in class were implemented to encourage students to use the web-based training environments. Overall, results do not show a robust effect of comparison feedbacks but confirm the crucial influence of procrastination and initial knowledge on students’ performance. The implications are discussed considering thenaturalistic nature of this research.
