ABSTRACT:  The purpose of this study was to use a validated instrument to determine the attitudes and knowledge of high school teachers regarding food irradiation, and to determine the correlations among their knowledge and attitudes and certain demographic variables. Knowledge and attitudes about food irradiation were measured in selected high school family and consumer sciences teachers ( n = 121) who taught Food and Nutrition, Food Science and Technology, and/or Food Production Management and Services, via a 24-item instrument with 6 factors. Results revealed these teachers held neutral to positive attitudes about the safety of irradiated foods, their perception of the risk of foodborne illness, and learning about food irradiation, and neutral to negative perceptions of their understanding of food irradiation and their competence to teach about it. These teachers had a moderate knowledge base regarding food irradiation. Teachers' attitudes regarding the safety of food irradiation were positively correlated with their perceived understanding of food irradiation, actual knowledge of it, and competence to teach about it. Their perceived understanding of food irradiation was positively correlated with competence to teach about it, knowledge, and attitudes toward the safety of food irradiation. The only demographic variable correlated with knowledge or attitudes was teachers' previous food irradiation educational experiences. These data suggest the importance of education for family and consumer sciences teachers concerning food irradiation.  相似文献

There is opportunity to decrease the frequency of foodborne illnesses by improving food safety competencies and planned behaviors of college students before they begin careers in the food industry. The objectives of this study were to (1) develop a multimedia case study teaching method that provides real world context for food science education; and (2) evaluate the extent to which it improves the intentions of students to implement food safety management systems upon entering the workforce, as well its impact on knowledge gains and students’ abilities to understand complex concepts. The target audience consisted of all participants in an upper‐level undergraduate food safety management systems course (n = 17). A pretest and posttest survey research instrument was developed to measure knowledge gains and also students’ food safety intentions using the framework of the Theory of Planned Behavior. Students experienced significant gains in knowledge, attitude, and intention after completion of the course (P < 0.05). One hundred percent of students agreed that the interactive videos aided in their understanding of food safety concepts. A paired t test suggested that both behavioral control beliefs and attitudes of students toward food safety management significantly increased (P < 0.5) after completion of the case study. These results suggest that integrating multimedia case studies into food science education may enhance food safety behaviors.  相似文献

ABSTRACT:  Commercial, nonthermal processing of food, such as high hydrostatic-pressure processing (HPP), has increased. The safety and quality of foods produced by HPP has not been well communicated to the public. An online, nationwide consumer survey was implemented to assess awareness of alternative food processing technologies, consumer food safety attitudes and knowledge, and willingness to pay (WTP) for HPP products. The consumer survey was administered by Zoomerang™, an online survey clearinghouse. The survey was completed by 1204 adults. Frequencies and crosstabs were calculated on Zoomerang and SPSS used for one-way ANOVA and chi-square analyses. The survey assessed knowledge of HPP, attitudes about new food processing techniques, WTP for HPP foods and demographics. Overall, many demographic characteristics reflected U.S. census population. While traditional methods, that is, canning, freezing, and microwaving were all well recognized by over 80% of respondents, only 8% recognized HPP. Trends indicated an increase in age, education, and income reflected greater food safety knowledge. Regardless of demographics, no survey respondent exhibited knowledge mastery (80%). Given an explanation of HPP and its benefits, 39% of respondents indicated they would be WTP an additional cost, with higher income and education having the most impact. Majority of respondents indicated a WTP of $0.25 to $0.50 regardless of the value of the food product. More respondents were WTP slightly more for a more expensive product. New technologies often encounter a stumbling block in consumer acceptance and processing costs. A consumer's WTP, once they were informed, could encourage industry to look favorably on this technology.  相似文献

To enhance the learning outcomes achieved by students, learners undertook a computer‐simulated activity based on an acid–base titration prior to a university‐level chemistry laboratory activity. Students were categorized with respect to their attitudes toward learning. During the laboratory exercise, questions that students asked their assistant teachers were used as indicators of cognitive focus. During the interviews, students' frequency and level of “spontaneous” use of chemical knowledge served as an indicator of knowledge usability. Results suggest that the simulation influenced students toward posing more theoretical questions during their laboratory work and, regardless of attitudes, exhibiting a more complex, correct use of chemistry knowledge in their interviews. A more relativistic student attitude toward learning was positively correlated with interview performance in both the control and treatment groups. © 2007 Wiley Periodicals, Inc.

Since formal education is guided through food‐related curricula, there is a concern regarding to which extent food safety elements are supported in the current educational objectives presented in syllabi. The aim of this study was to analyze the existing food safety elements in the syllabi at the elementary (for students between 6 and 14 y of age) and upper‐secondary level (food‐related programs) of formal education (for students between 15 and 18 y of age). Analysis was done through predefined criteria, evaluating the educational objectives listed in available syllabi approved by the national government. The results revealed the elementary level as a good prestage for education at the next level concerning food safety elements. At the upper‐secondary level, the acquisition of knowledge and development of skills related to food safety elements of interest are well supported. However, based on frequent errors made by professional food handlers reported in the literature, the role of food handlers and their food safety awareness should receive more attention in the syllabi. To support this and to overcome a lack of educational objectives identified, several actions are suggested. Based on methodological recommendations for the teacher in the syllabi, the importance of qualified teachers was once again confirmed. Vocational schools are and will remain an indispensable pillar in the education of future professional food handlers; however, teachers with sufficient knowledge and a positive attitude toward food safety seems to be, besides quality curricula, one of the important factors in achieving the proper attitudes of people required to implement food safety.  相似文献

This preliminary study investigated 118 special education doctoral students’ knowledge of and attitudes toward self-determination. In addition, this study examined the relationship between self-determination coursework and special education doctoral students’ perceptions of how well they were prepared for implementing self-determination in their future careers. The results indicated that although the majority of respondents possessed adequate knowledge of self-determination concepts, they reported lacking confidence in identifying how it can be taught and assessed. Most of the respondents indicated that they would integrate self-determination knowledge and skills into their future teaching; however, more than one-half of the doctoral students felt that they were unprepared with regard to the instruction of self-determination. Also, the findings indicated that there were statistically significant relationships between pre-service courses and doctoral students’ perceptions of self-determination. The results of this study showed a gap in current doctoral students’ knowledge about self-determination and confidence related to application within pre-service teaching.  相似文献

The purpose of this mixed‐methods study was to explore special education teachers’ attitudes towards using technology in inclusive classrooms in Oman. The sample consisted of 428 special education teachers working in Omani public schools (250 teachers of students with learning disabilities (LD), 90 teachers of students with intellectual disability and 88 teachers of students with hearing impairment). Participants responded to the attitudes towards computers questionnaire. For the qualitative section of this study, three semi‐structured group interviews were conducted with a group of special education teachers: 15 teachers of students with hearing impairment, 15 teachers of students with intellectual disabilities and 15 teachers of students with LD). Also, the teachers responded to a survey of educational technology which encompassed seven questions about computer technology. Results of the study indicated that the special education teachers’ attitudes towards using computers were generally positive. The most notable positive attitudes were in the following subscales: special education considerations, staff development considerations, computers use in society, and computers and quality of instruction issues. The analysis of variance results showed that experience and type of disability did not have a significant effect on teachers’ attitudes towards technology.  相似文献

This study serves as a pilot study for a longitudinal study that will be conducted a year later. The purpose of this research is to determine how a course in special education has impacted secondary general education pre‐service teachers’ attitudes towards individuals with disabilities, teaching students with mild disabilities and the degree of their preparedness (self‐reported) in working with students with disabilities. Forty‐two secondary pre‐service teachers’ reflection papers written at the beginning and end of a mandatory special education course (16 weeks) were analysed using qualitative methodology. The findings supported our research hypothesis that a course in special education with necessary components (i.e. introductory special education knowledge, activities designed to enhance students’ dispositions toward students with disabilities, and instructional strategies that will help general education teachers teach students with mild disabilities at the middle and secondary levels more effectively) can be effective in preparing secondary education pre‐service teachers to work in inclusive classrooms.  相似文献

This study examined Finnish elementary school teachers’ (N = 212) attitudes toward the gifted and their education. On a general level, teachers’ attitudes toward gifted education were slightly positive. Teachers saw that gifted students have social value and that they need special services. The results of teachers’ attitudes toward specific gifted education options were in line with earlier Finnish research, because teachers supported differentiated teaching but were more negative toward acceleration or separating the gifted into their own groups. However, despite the strong support for differentiated teaching for the gifted, teachers’ positions toward practice were more skeptical.  相似文献

This article reports on a mixed-method inquiry into pre-service and in-service secondary school teachers’ knowledge about Attention-deficit Hyperactivity Disorder (ADHD) and attitudes toward students with this disorder in Hong Kong. The inquiry revealed no differences between pre-service and in-service secondary school teachers concerning their knowledge of ADHD and attitudes toward students with ADHD. It also identified possible sources of participants’ knowledge and a variety of factors underlying their attitudes toward students with ADHD including sociocultural beliefs and working conditions. The findings call for teacher educators to develop better education programmes to support both pre-service and in-service teachers in undertaking the challenging task of teaching students with ADHD.  相似文献

High school students’ prevalence as food‐service industry employees and their lack of food safety knowledge make them prime candidates for food safety education. The researchers developed a food‐safety‐focused curriculum for high school students aligned with Indiana Academic Standards for Agriculture, Advanced Life Science: Food. The curriculum was designed to provide students with fundamental food safety concepts through experiential learning and incorporation of science, technology, engineering, agriculture, and mathematics (STEAM) activities in the context of different careers related to agriculture, especially in food science. This study uses the Delphi technique to evaluate the food safety curriculum, including the identification of barriers to incorporating the curriculum into classrooms. The Delphi technique uses an expert panel to generate consensus related to a topic. A panel of experts in the field of education evaluated the curriculum through three rounds of surveys containing questions related to six curriculum assessment topics. Experts rated the degree to which they agreed with statements about the curriculum using a 5‐point Likert scale and multiple‐choice questions. At the conclusion of the study, the cost to purchase materials for cooking labs was the only identified barrier to curriculum incorporation (62.5%). Experts agreed that the curriculum addressed academic standards (100%), was engaging for students (100.0%), was easy for teachers to use (89.5%), and successfully incorporated STEAM (100.0%), experiential learning (89.5%), and career‐education (78.9%). This study highlights the feasibility of providing food safety education to high school students in less traditional disciplines while promoting career development through the incorporation of experiential learning, STEAM, and career‐education components.  相似文献

ABSTRACT:  Providing effective food safety education to young consumers is a national health priority to combat the nearly 76 million cases of foodborne illness in the United States annually. With the tremendous pressures on teachers for accountability in core subject areas, the focus of classrooms is on covering concepts that are tested on state performance examinations. As a result, topics such as food safety are rarely addressed in middle school classrooms. Middle school is an ideal time to teach food safety because adolescents are in the process of setting lifelong behaviors; therefore, they are more likely to synthesize new food safety knowledge in a way that will lead to the development of lifelong behaviors. The purpose of this study was to scientifically validate an educational resource that provides a method for classroom teachers to involve young consumers in food safety education while meeting state content area curriculum standards. An interdisciplinary curriculum targeted at middle school students and correlated directly to state content standards was designed to include highly effective instructional strategies that teach food safety concepts through all core subject classes (science, math, social studies, and language arts). The curriculum was pilot tested in 5 schools using a pretest, posttest, and follow-up test assessment model. The results showed that the curriculum was highly effective at raising student knowledge (21% gain) and improving students' food handling behaviors (8.47% gain) from pretests to posttests. In addition, 6 wk after implementation, students retained 86% of their total knowledge gain as measured by a follow-up assessment.  相似文献

Abstract

Teachers’ attitudes toward inclusion of children with disabilities play a central role in the successful inclusion of these children into general education classrooms. This study examined possible predictors of preservice teachers’ attitudes toward (1) persons with disabilities, and (2) inclusion of children with disabilities into general education classrooms. Participants were students majoring in early childhood education and elementary education. Preservice teachers’ attitudes toward persons with disabilities and inclusion were explained significantly by their personal relationships with persons who have disabilities and the number of courses related to special education/teaching strategies taken. However, preservice teachers’ experiences working with persons who have disabilities was not a significant predictor. Further, the relations between preservice teachers’ attitudes toward inclusion and personal experience variables were mediated by their attitudes toward persons with disabilities. This study provides evidence that more effective, practical experiences and course content related to children with disabilities, inclusion, and teaching strategies need to be provided in teacher education programs to support successful efforts with inclusion. This study also suggests that teacher education programs should strive to improve students’ attitudes toward inclusion, as well as toward persons with disabilities.  相似文献

There is a distance between the power that whole class dialogic discussions (WCDD) may offer to the science class and their use in practice. Teachers’ attitudes toward WCDD are part of the problem. The aims of this study were twofold: (a) to examine Taiwanese physics teachers’ attitudes toward WCDD by considering cultural perspectives and describe how these attitudes changed as a result of a special workshop designed for this purpose, and (b) to report on how these attitudes should be taken into account in designing such workshops in the future. Nine experienced physics teachers participated in the WCDD workshop. The workshop was based on the WCDD model developed by Eshach (2010). Inductive analyses were performed on interviews with the teachers and their students, which were composed of 36 questions and developed specially for the purpose of this study, yielded the following categories: (1) In-school reasons for opposing WCDD—reasons belonging to school ways/tradition of teaching that may cause barriers to WCDD implementation; (2) External Factors—cultural reasons relating to Taiwanese views concerning education in general, which cause barriers to WCDD implementation; and (3) Cognitive aspect—refers to what teachers know about WCDD. The paper concludes with a discussion on what should be done in order to successfully bring WCDD to the Taiwanese physics class.  相似文献

Abstract: This article describes an innovative assessment tool designed to evaluate the effectiveness of a food safety skills curriculum for learners receiving special education services. As schools respond to the increased demand for training students with special needs about food safety, the need for effective curricula and tools is also increasing. A Food Safety Education for High School and Transition Special Needs Students curriculum served as the basis upon which our assessment tool was developed. The project was a collaborative effort by food safety and education professionals in Connecticut, Rhode Island and Massachusetts. This USDA‐funded initiative emerged from teacher‐generated data that identified critical gaps in food safety knowledge and skills among students with disabilities (SWD) receiving special education services. As an adjunct to this curriculum, a Food Safety Practices Assessment Tool was developed to: 1) conduct observations of students as they demonstrate food safety practices, and 2) use this information to design classroom‐based learning activities that are aligned with students’ Individual Education Plans (IEP). Pilot data suggest that the tool is valid and reliable for use in a kitchen‐based setting. This is the first known tool of its kind to test food safety skills of individuals with special needs in a real‐world environment. Further testing is needed to determine the usefulness of the tool for broader audiences.  相似文献

Bali's subak cultural landscape, with its ancient and extensive paddy-fields and irrigation system, is a valuable resource for place-based education. However, this landscape is threatened by various problems. Here we analyze the relationships among Balinese teachers, student teachers, and students, and review their knowledge, attitudes, and experiences toward subaks. This study finds that most of the Balinese teachers, student teachers, and students had limited knowledge and experiences regarding subaks, although their overall attitudes were positive. We conclude by discussing the study's implications for relocating environmental education into the local context.  相似文献

In the current study, we focus on teacher-student discourse in Pre-K science activities, with particular attention to teacher questioning. Videotaped classroom observations and teacher interviews served as the corpus of data. Overall, teachers asked mostly closed-ended questions, but used more open-ended questions when experiments were being conducted. During experiments, teachers?? questions were aimed at prediction and reasoning. In contrast, teachers used primarily closed-ended questions when science skills were being practiced and during science book readings, when their questions were oriented toward recognition and recall of factual information. The effects of the teachers?? questions can be seen in the students?? responses. When questions were open-ended, students employed a more varied vocabulary and more complex sentence structures. When teachers?? questions were oriented toward prediction and reasoning, students practiced these higher level cognitive skills in responding. Based on these findings, we provide recommendations for teaching practice in early childhood science education.  相似文献

The purpose of this study was to investigate attitudes toward mainstreaming issues of elementary classroom teachers undertaking an introductory course in special education. Subjects were also queried about how they felt P.L. 94‐142 was perceived by other interested groups and indicated their estimates of the manageability of students with special needs within the regular classroom. Findings support the need for comprehensive in‐service training programs designed to modify attitudes of regular teachers.  相似文献
