Abstract: A modified problem‐based learning (PBL) exercise was implemented in a food science Dairy Products course, which had previously been taught in the traditional lecture and laboratory format only. The first 10 wk of the course consisted of weekly lectures and laboratory exercises. During the remaining 3 wk, students were presented with a case study that described milk quality problems that could be encountered by the dairy industry. Each week, students received a set of case disclosures containing relevant information that assisted in solving the case. Students were asked to present their findings at the end of the course in the form of a written “consultant's report.” In addition, students were given a survey asking for feedback on the PBL exercise, and the usefulness of having the lectures and labs prior to the PBL experience. Eighty percent of the students found that lectures and labs provided them with sufficient background knowledge to understand and solve the PBL case, 70% found that the PBL reinforced course material covered during lecture and labs, 50% responded that PBL helped them develop new ways of reasoning about the subject matter and 65% reported that PBL taught them to think critically. Of the total students surveyed, 56% would prefer to participate in similar types of PBL exercises in the future. Incorporating PBL into traditionally taught food science courses can have a positive influence on the learning process. 相似文献

ABSTRACTThis study explored whether three-dimensional wisdom and psychosocial growth, defined as increases in psychological well-being (PWB), spirituality, and death acceptance, can be learned in university courses. Specifically, the study examined whether courses that tried to engage the whole person rather than only the intellect and/or courses that included a service learning component (growth classes) fostered greater wisdom and psychosocial growth than regular sociology or religion courses (control classes). Results of repeated measure MANOVAs showed that, on average, the 165 students who were enrolled in 12 growth classes significantly increased in wisdom, PWB, spirituality, and death acceptance between the beginning and the end of the semester, whereas the 153 students who attended eight control classes significantly decreased in wisdom and did not change significantly in PWB, spirituality, and death acceptance. It appears that it is indeed possible to learn wisdom and psychosocial growth in university courses. 相似文献

This study adopted a longitudinal retrospective case study approach to investigate Chinese business students’ transitional learning experience in a problem-based learning (PBL) course with innovative assessment practices. The study focused on students’ beliefs and strategy use in a constructively aligned PBL course for business communication. Eight students who had made notable progress were chosen for retrospective analysis. The data included 48 journal entries, interviews, and writing samples collected at different stages of the course. This study identified taxonomies of participants’ beliefs about learning and writing, their perceptions of assessment, and their strategy use for learning. It also examined changes in beliefs, perceptions, and strategy use to determine the nature of the students’ learning experience in this PBL course. Findings suggest a recognised need to design PBL courses that align social constructivist learning principles with students’ beliefs and strategies. The results also highlight the importance of developing appropriate assessment rubrics to enhance student engagement with PBL learning for improved outcomes. 相似文献

ABSTRACT: The U.S. Dept. of Agriculture recommends use of food thermometers to safely cook small cuts of meat, yet most consumers do not use them. Consumers lack knowledge about how and why to use food thermometers with small cuts of meat. Opportunities exist for family and consumer science classes to provide education about thermometers to adolescents, who may disseminate this information to parents. The most successful nutrition programs are based on behavior-change theories compared with standard interventions. A teaching kit for high school students was developed, based on the Health Belief and Transtheoretical Models, covering the "how's" and "why's" of using food thermometers. After participating in the lessons, students' knowledge about the reasons for using a thermometer and their self-confidence in using thermometers increased. In addition, students were more ready to use a thermometer with small cuts of meat after completing the intervention. 相似文献

The purpose of this paper is to investigate the impact of problem-based learning (PBL) on freshmen engineering students’ beliefs about physics and physics learning (referred to as epistemological beliefs) and conceptual understanding of physics. The multiple-choice test of energy and momentum concepts and the Colorado learning attitudes about science survey were used to collect the data. The sample consisted of 142 students enrolled in the PBL and traditional lecture classes in the engineering faculty of a state university in Turkey. The analyses showed that the PBL group obtained significantly higher conceptual learning gains than the traditional group and the change (improvement) in the PBL group students’ beliefs from the pre- to post test were significantly larger than that of the traditional group. The results revealed that beliefs were correlated with conceptual understanding. Suggestions are presented regarding the implementation of the PBL approach. 相似文献

We report on an investigation of students' ideas about gravity after a semester of instruction in physics at university. There are two aspects to the study which was concerned with students' answers to a carefully designed qualitative examination question on gravity. The first aspect is a classification of the answers and a comparative study of the ways the problem was tackled by two large groups of students who had different backgrounds in physics and were exposed to different teaching styles. The second aspect is to investigate how students link concepts to solve the problem. We used a phenomenographic analysis of student responses to extract patterns of reasoning and alternative conceptions behind the solutions. We found no differences between the classes of answers given by students in the two courses. Our analysis also identifies a hierarchy in the complexity of the hypothetical reasoning pathways, which we interpret as reflecting the ways in which students may link concepts and resolve conflicts as they solve the problem. The hypothetical reasoning pathways may help educators to develop instructional material or lecture room dialogue in order to tease out key issues. An unexpected finding is that there is a discrepancy between our conclusion that the two groups of answers are similar and the distribution of marks awarded by the examiner – which implies that the quality of the answers is different for the two groups. 相似文献

This paper describes an investigation of concepts that various groups hold about food and nutrition. Groups investigated were
students in Years 4 and 8, university students in a BEd (primary) program and parents of the Year 4 students. It was found
that for many important concepts relating to food selection, the basic ideas of each group were surprisingly consistent, despite
the influence of formal education. In particular, misconception about energy and its role in nutrition and particular food
groups was an important finding. Implications for school and community education are drawn from the results.

ABSTRACT: Consumer interest in healthy foods has spurred approval of several health claims for foods and dietary supplements. Although undergraduate and graduate food science curricula address food laws and regulations, nutrition claims may not be fully addressed. We posted a survey on the Internet for 2 mo for food industry professionals and others interested in taking the survey to assess their understanding of laws and regulations pertaining to nutrition labeling for foods and dietary supplements. The purpose of this survey was to measure knowledge in this area so that our university and others could reevaluate their curricula to provide student and lifelong learners with appropriate information about this important topic. Respondents were asked to indicate whether displayed claims were health claims, structure-function claims, or not approved for use on food labels. Respondents ( N = 136) indicated that they gained information about nutrition claims from many sources. Although respondents correctly identified approved health claims and claims that are not approved for foods, some confusion about nutrition claims may exist because not all respondents correctly identified claims in the appropriate category. Issues in educating food scientists include keeping food labeling information current and defining complex topics such as structure-function claims. The findings of this pilot study have been used to incorporate lectures about health claims in courses in addition to the food law class at the Univ. of Maine. 相似文献

Nationwide, the percentage of faculty who are tenured (or in tenure-earning positions) is declining, with proportionate increases in the amount of instruction provided by adjunct and other part-time instructors, including doctoral students. These trends are mirrored within academic social work and have given rise to some concerns about the potentially adverse effects this could have on the quality of instruction provided to MSW and BSW students. A review of the social work literature, however, failed to locate any systematic investigations published on the topic of evaluating the quality of teaching provided by adjuncts or doctoral students. The authors undertook a comprehensive analysis of the course evaluations obtained from a large urban school of social work in the Southeast over a 3-year period, covering 294 courses (61% BSW, 39% MSW). Of these, 181 classes were taught by regular faculty, 63 classes were taught by community-based adjuncts, and 50 classes by social work PhD students. Inferential tests found no statistically significant differences in the global course evaluations earned by regular faculty or adjuncts. However, there were statistically significant differences in the course evaluations earned by regular faculty and doctoral students, favoring the former, but the effect size was small and of little practical import. In general, the authors found no strong evidence that adjuncts or doctoral students provided less positively evaluated teaching than did regular faculty. The authors' results are limited to one university setting but their research design can be readily adopted by other programs, given the widespread use of quantified student-completed course evaluations generally maintained on university databases. More serious attention needs to be given to determining whether the course evaluations commonly used by universities are truly valid. 相似文献
