Item Open Access An assessment of the effects of teaching methods on academic performance of students in accounting courses(Routledge, 2010) Hosal-Akman, N.; Simga-Mugan, C.This study explores the effect of teaching methods on the academic performance of students in accounting courses. The study was carried out over two semesters at a well-known university in Turkey in principles of financial accounting and managerial accounting courses. Students enrolled in the courses were assigned to treatment and control groups. Treatment group students solved assigned problems or cases in groups in class, while in the control group the instructor lectured on and solved the problems and cases. The results of the study show that there was no significant difference in the academic performance of the treatment and control group students in either course.Item Open Access Distributed online learning via cooperative contextual bandits(Institute of Electrical and Electronics Engineers, 2015-07-15) Tekin, C.; Schaar, Mihaela van derIn this paper, we propose a novel framework for decentralized, online learning by many learners. At each moment of time, an instance characterized by a certain context may arrive to each learner; based on the context, the learner can select one of its own actions (which gives a reward and provides information) or request assistance from another learner. In the latter case, the requester pays a cost and receives the reward but the provider learns the information. In our framework, learners are modeled as cooperative contextual bandits. Each learner seeks to maximize the expected reward from its arrivals, which involves trading off the reward received from its own actions, the information learned from its own actions, the reward received from the actions requested of others and the cost paid for these actions—taking into account what it has learned about the value of assistance from each other learner. We develop distributed online learning algorithms and provide analytic bounds to compare the efficiency of these with algorithms with the complete knowledge (oracle) benchmark (in which the expected reward of every action in every context is known by every learner). Our estimates show that regret—the loss incurred by the algorithm—is sublinear in time. Our theoretical framework can be used in many practical applications including Big Data mining, event detection in surveillance sensor networks and distributed online recommendation systems.Item Open Access The effects of cooperative learning activities on student attitudes towards English reading courses and cooperative learning(Bilkent University, 2004) Bayat, ÖzlemThe purpose of this study was to investigate the effects of cooperative learning activities on student attitudes towards English reading courses and cooperative learning. Possible differences in attitudes in terms of gender and achievement level of students were also investigated. The study was conducted with one control and one experimental group. In total, 40 students participated in the study. Following a work shop on the implementation of cooperative learning activities, the teacher taught the experimental group using cooperative learning activities. The control group was taught using traditional whole class methods. Questionnaires were given to both groups before and after the four-week treatment. Interviews were also conducted with the teacher and randomly selected students. Questionnaire data were analyzed by t-tests and ANOVA tests. According to the results of these tests, no significant differences after the treatment were found between the control group and the experimental group responses related to their attitudes towards English reading courses and cooperative learning. In within-group comparison, however, the experimental group’s attitudes towards the English reading course was significantly more negative, whereas no change was found in the control group. Gender and achievement level were found to have no significant influence on students’ attitudes towards English reading courses and cooperative learning. Data collected in teacher and student interviews, however, suggested that cooperative learning had positive effects on attitudes towards English reading courses. In addition, both the teacher and the students reported positive attitude towards cooperative learning.Item Open Access Scribbling stage : a case study on strategies for teaching music composition to grade 3 students(Bilkent University, 2016-12) Pınarbaşı, Fatma ŞafakThis research explored strategies to scaffold 3rd grade students as they learn to compose music in small groups in an elementary school in Turkey. The purpose of the study was to investigate how the teacher can use different strategies to teach composing in small groups. The research method was designed as a case study to examine a professional music teacher and 19 students working in small groups throughout four lessons. The data were collected by classroom observations, interviews with individual students, the teacher, focus groups and reflections from the teacher. Results indicated that the teacher used modeling, inquiry, connected starters to the concept of composing music, purposefully creating students groups before the tasks and remained flexible to respond to student needs that occurred during the composition tasks. The evidence suggested that other important group dynamics also occurred while students were peer scaffolding. Students who had no experience in composing in small groups had a change in mindset after the composition tasks. Student reflections further revealed how composing music in small groups helped them to improve their musical and cooperative skills.
