A hands-on practical was developed to simplify detection of enzyme activity of amylase, protease and lipase on starch agar, dry whole milk agar, and trihutyrin agar, respectively. The subjects of the study were 24 senior undergraduates who studied in the Program of General Science, Faculty of Science, Srinakharinwirot University, Bangkok, in three semesters during 2007 - 2008. The basic concepts of enzymes, e.g., substrate specificity, how to detect enzymes and optimal enzyme conditions, were taught before the practical. The first enzyme, protease, was used in the second semester of 2007, and then changed to be lipase and protease in the first and second semesters of 2008, respectively. Ten open-ended questions were used to assess students in all semesters. In agreement with the constructivist learning model, it was demonstrated that students had learning retention and applied their prior knowledge to other enzyme experiments.展开更多

Fifty seven students working on a real classroom assignment were observed; in order to make sure that the subjects behaved as they normally would, they had not been informed that their dictionary behavior was to be observed. The study which shows that the need for a dictionary is smaller in the case of more advanced students may be of interest to those foreign language teachers who fear that giving a student an unlimited access to a dictionary may hamper the development of his expressive abilities. In turn, a marked preference on the part of more advanced students for an L I-L2, paralleled by a sustained interest in information categories typically placed in foreign learner＇s dictionaries suggests that advanced language learners writing in English would probably opt for a lexicographic product combining the best of both dictionary types： an LI-L2 and an MLD.展开更多

It highlights that school teachers need to acknowledge students＇ preferred learning methods, especially those of minority backgrounds like the Samoan participants in this investigation. A detailed exploration of the experiences of students in two HSGs finds that while students and their families place a high priority on learning, their cultural practices are not compatible with standard Western learning approaches. The HSGs provided a social space in which students could ask the teacher questions without fear of appearing foolish, in which they could apply themselves to study. It provided a physical study space away from the demands some Samoan families place on their young people, and it provided a cultural space in which the students could learn according to fa＇aSamoa （traditional values and beliefs）. This research makes a contribution to an understanding of the motivations of Melbourne-based Samoan students to learn, of what concerns them, and of impediments to their educational success. It also offers insight into the benefits that set up a specific space for students offers, when its specific intent is influencing the merging of Samoan and Western ideas to further learning.展开更多

Growing initially out of interest generated by national speech competitions, English public speaking has become a sought-after subject because of its value in today＇s globalized world. Focusing on English as a working language, it strengthens core skills and competencies not just in oral communication, but also in writing, listening, critical thinking, intercultural communicative competence, and overall English proficiency. Grounded in the Western discipline of rhetoric, it is being localized in China through creative adaptation by teachers and students alike.展开更多
