Previous studies have reported on the inadequacy of youth knowledge and practice of food safety principles. The formal high school science classroom environment presents an opportunity to stimulate interest and increase knowledge in food safety with potential benefits to students in improved science literacy, development of life skills, and greater awareness of career opportunities. Previously developed educational materials, Foodborne Illness Outbreak Investigations for Food Safety Education, were evaluated for instruction by high school and community college science educators of various subject matters including foods, microbiology, disease, and chemistry courses. Educator feedback was favorable on measures of quality, implementation ease, and student engagement, with ratings greater than 3 on a 5‐point scale corresponding to “good” to “excellent.” A positive change in familiarity with food safety concepts for 4 groups of students, representing approximately 77% of the participants, was demonstrated by an overall increase, ranging from 4% to 14%, in correct responses to a test administered before and after exposure to the materials. There was variation in degree of change and the topics positively impacted for student groups by subject matter.  相似文献

Importance of online learning has become more critical with the advent of a global pandemic. Effective online learning requires design characteristics that support learning that crosses traditional disciplinary boundaries. The example of educational delivery of food safety encompasses multiple disciplines to prepare students for real‐world situations, practical problem‐solving, and to be “future proof” as food safety becomes more quantitative. This study explicates how six simulation‐based learning modules were evaluated, two each in microbiological growth/inactivation, food process dynamics with microbiological growth/inactivation, and risk assessment. Each group of three modules was targeted to the students in undergraduate food science and engineering programs. Altogether, the 6 modules were implemented and assessed in 17 courses at 14 universities over 5 years. The effectiveness of the module‐based approach was sustained across subject matter (microbiology, process, and risk), disciplines (food science and engineering), and their implementations. Students’ and instructors’ survey responses indicated the modules’ value in real‐world and practical problem‐solving ability. Instructors were also motivated to implement the modules as they saw the potential for improvement in student understanding, how modules reinforced course learning outcomes, the quality of support provided with modules, and their ability to replace existing course assessment without adding work for the instructor or the students. This self‐learning, module‐based approach to introduce interdisciplinary content employed has proven successful. The template for making these modules is described in sufficient detail so future modules can be built for a wide variety of subject matter beyond food safety.  相似文献

Engaging undergraduate students in research has become increasingly important due to its potential benefits (for example, increased intention to pursue postgraduate study and enhanced understanding of theoretical knowledge). This study investigated whether a comprehensive food science research project that was incorporated into the laboratory component of an Experimental Study of Foods course would enhance student knowledge, confidence, and interest in research. A total of 84 students participated in two sections of the laboratory (2016, n = 39; 2017, n = 45). Scores for pre and posttests and questionnaires were used to determine if the differences in knowledge scores and ratings for confidence in doing research were significant. Knowledge scores indicated that participants were knowledgeable about research at baseline (2016, 7.31 ± 1.15; 2017, 6.89 ± 0.1.21; maximum of 10 points). Results of the t‐tests showed that the change in knowledge scores before and after the project was not statistically significant; however, the level of confidence in performing various research skills (for example, identify research questions, formulate hypotheses, design an experiment) significantly increased upon project completion. In general, students demonstrated favorable attitudes toward the research project at the end of this project. Qualitative responses were organized into three themes that related to the “input” (elements that made the project successful), “process” (how the project was conducted), and “outcomes” (reported gains or benefits) of the project. Recommendations were made in terms of mentorship, research guidelines and topics, and group culture to improve future projects.  相似文献

Proper grammar is crucial for effective communication. Two surveys of students in an introductory writing course sought to identify predictors of grammar ability. Students demonstrated a limited grasp of the language, struggling with such issues as the distinction between “it's” and “its.” Women performed better than men at the beginning of the semester, but the gap later narrowed. There was a correlation between self-efficacy (confidence in one's ability to perform a particular task) and grammar ability at the end of the semester. To the knowledge of the authors, this is the first study to empirically link grammar self-efficacy and grammar performance. High school grade point average also predicted grammar ability at the end of the semester.  相似文献

A 44 item questionnaire and free response instrument was given to 280 students selected from two different kinds of introductory educational psychology courses: (a) A “module”; approach involving selection of 3 five‐week modules from a list of such courses; and (b) A specially prepared composite learning and development course covering 1 semester. Analysis of the results lead to the following conclusions: (1) “In theory”; students preferred the module approach; (2) “In practice”; students preferred the composite 1 semester course; (3) The outstanding variable contributing to students’ assessment of relevancy, and teaching procedures, was the instructor. The implication of these findings for innovations in teaching students is discussed.  相似文献

“What is that sound?”, “What did the kangaroo say?”, and “What might you hear during a walk?” provide evidence that educators of young children realize that listening represents a necessary ingredient in successful school experiences. Children listen for many hours of the school day, but listening has been a neglected area of instruction. The traditional low priority of listening instruction may have been based upon the myth that children naturally learn to listen or on the misconception that listening skills cannot be taught. Using literature to teach listening can improve learners' listening abilities, provided early childhood educators use developmentally appropriate children's literature.  相似文献

Several cognitive psychologists have written about the importance of placing instruction within “authentic” contexts that mirror real-life situations. They argue that knowledge learned in academic settings does not necessarily transfer to non-academic settings. Whether preparing performance technologists or instructional designers, educators must strive to create meaningful problem-solving contexts that enable students to define, and subsequently solve, real-world problems. In an attempt to address this issue we have modified the way we teach instructional design. This paper discusses a cognitive apprenticeship approach to teaching design, which incorporates elements of modeling, coaching, reflection, articulation, and exploration. We describe how these features are embedded within three phases (orientation, situated training/learning, and exploration) of an introductory instructional design course designed to move our novice designers along a continuum of expertise as they develop and refine their own professional design skills. Although the apprenticeship model described here specifically addresses concerns within the context of preparing instructional designers, we believe that this model can be adapted to address similar issues in the education of performance technologists.  相似文献

民国时期是一个大动荡时期，此间支配阶级眼中的中小学教师身份认同流变，若按政权更迭为主线加以考察，则分别经历了新民教化者、封建捍卫者、军政训导员、抗战宣传员、赤化避免者五个大阶段，因其政权性质与总体施政纲要不同，每个阶段支配阶级对教师的要求又各具不同特点，但均为教师工具性特点的体现，亦为各自政权巩固所需。  相似文献

This paper describes an attempt at evaluating a potentially critical “detail” of teaching practice; that is, using a particular diagram to illustrate the imaging role of a converging lens. This “basic” diagram has been designed to contribute to help students overcome the well‐known “travelling image” syndrome. We conducted a comparative study with 125 students in all, at three academic levels: end of secondary school, degree students, and teacher training. The groups compared had previously been taught elementary optical imaging in a classical, uncontrolled manner, and were presented with two classical questions, commonly used to demonstrate students’ difficulties. In each group, one‐half of the students had a classic introductory diagram and the other half had the “basic” one. A positive reaction of students to the evaluated diagram was observed at a relatively high academic level (trainee physics teachers and degree students), in contrast with an apparent lack of effect at the end of secondary school. The paper ends with a discussion of the evaluation of a detail of practice in isolation, with respect to the distance between students’ actual and targeted levels of comprehension.  相似文献

There is an increasing need for students in the biological sciences to build a strong foundation in quantitative approaches to data analyses. Although most science, engineering, and math field majors are required to take at least one statistics course, statistical analysis is poorly integrated into undergraduate biology course work, particularly at the lower-division level. Elements of statistics were incorporated into an introductory biology course, including a review of statistics concepts and opportunity for students to perform statistical analysis in a biological context. Learning gains were measured with an 11-item statistics learning survey instrument developed for the course. Students showed a statistically significant 25% (p < 0.005) increase in statistics knowledge after completing introductory biology. Students improved their scores on the survey after completing introductory biology, even if they had previously completed an introductory statistics course (9%, improvement p < 0.005). Students retested 1 yr after completing introductory biology showed no loss of their statistics knowledge as measured by this instrument, suggesting that the use of statistics in biology course work may aid long-term retention of statistics knowledge. No statistically significant differences in learning were detected between male and female students in the study.  相似文献

Understanding the roles of random selection and random assignment in experimental design is a central learning objective in most introductory statistics courses. This article describes an activity, appropriate for a high school or introductory statistics course, designed to teach the concepts, values and pitfalls of random selection and assignment using the not‐easily‐forgotten Madagascar hissing cockroach. Evidence is summarized demonstrating conceptual gains for students performing the Randomizing Roaches activity, and follow‐up activities are suggested.  相似文献

Educational tools claiming to use “right‐brain techniques” are increasingly shaping school curricula. By implying a strong scientific basis, such approaches appeal to educators who rightly believe that knowledge of the brain should guide curriculum development. However, the notion of hemisphericity (idea that people are “left‐brained” or “right‐brained”) is a neuromyth that was debunked in the scientific literature 25 years ago. This article challenges the validity of “right‐brain” teaching, highlighting the fact that neuroscientific research does not support its claims. Providing teachers with a basic understanding of neuroscience research as part of teacher training would enable more effective evaluation of brain‐based claims and facilitate the adoption of tools validated by rigorous independent research rather than programs based on pseudoscience.  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

In the current No Child Left Behind era, K‐12 teachers and principals are expected to have a sophisticated understanding of standardized test results, use them to improve instruction, and communicate them to others. The goal of our project, funded by the National Science Foundation, was to develop and evaluate three Web‐based instructional modules in educational measurement and statistics to help school personnel acquire the “assessment literacy” required for these roles. Our first module, “What's the Score?” was administered in 2005 to 113 educators who also completed an assessment literacy quiz. Viewing the module had a small but statistically significant positive effect on quiz scores. Our second module, “What Test Scores Do and Don't Tell Us,” administered in 2006 to 104 educators, was even more effective, primarily among teacher education students. In evaluating our third module, “What's the Difference?” we were able to recruit only 33 participants. Although those who saw the module before taking the quiz outperformed those who did not, results were not statistically significant. Now that the research phase is complete, all ITEMS instructional materials are freely available on our Website.  相似文献

This is a qualitative study to determine changes in the motivation of senior student teachers to teach (at the elementary, early childhood, and secondary levels) in an urban setting during the student teaching internship in an urban public school. Emerging themes include roles of classroom teachers, discouragement from tenured teachers, school bureaucracy, views of students, relationships with cooperating teachers, candidates' views about subject matter, and their views about themselves. The findings indicate that motivation to teach changed during student teaching. This cohorts' experiences strengthened their confidence and commitment to teach in culturally diverse urban public schools rather than discouraging them. This research supports a contextual approach to understanding motivation and challenges educators to reflect on several issues of preservice training as well as collaboration with teacher practitioners. With a knowledge of what attracts teachers to the occupation and an understanding of how that attraction is influenced by field experiences in urban schools, programs which prepare teachers may be better able to educate teachers who want to teach in urban schools and can perform successfully in that setting.  相似文献

In this paper, I report on a school‐university collaborative research project that investigated which practices and knowledges of Canadian Aboriginal students not acknowledged in school may provide these students with access to school literacy practices. The study, which took place in a small city in Western Canada, examined ways to merge the out‐of‐school literacy resources with school literacy practices for minority language learners who struggle with academic literacies. Drawing on the third space theory, in conjunction with the concept of “funds of knowledge,” I explain how students' linguistic and cultural resources from home and community networks were utilised to reshape school literacy practices through their involvement in the Heritage Fair programme. I analyse a representative case study of Darius, a 10‐year‐old boy who explored his familial hunting practices for his Heritage Fair project. This illustrative exemplar, “Not just sunny days,” highlights the ways in which children's out‐of‐school lives can be used as a scaffold for literacy learning. In conclusion, I discuss implications for educators and researchers working to improve literacy learning for minority students by connecting school learning to children's out‐of‐school learning.  相似文献

The aim of this study was to scrutinize the assessment of teacher knowledge in a school‐based course at one Swedish pre‐service teacher education program. In a general education school‐based course, teacher educators visited the student teachers at their school placements and met them and their school mentors in student‐teaching conferences to assess their teacher knowledge. The findings primarily show that the assessment procedures are influenced by teacher educators’ organization of the school visits and conferences. Secondly, the organization of the school visits and conferences influences who the potential and actual assessors at the conferences can be and are. Thirdly, the assessed student teacher knowledge at the conferences is described as procedural knowledge in a knowledge‐in‐practice perspective, almost exclusively in the area of relational, emotional, and caring learning objectives and aspects of teaching activities. Fourthly, the findings show that propositional knowledge in a knowledge‐for‐practice perspective is hardly mentioned or assessed.  相似文献

Management science professors who teach large classes often assess students with multiple‐choice questions (MCQs) because it is efficient. However, traditional MCQ formats are ill‐fitted for constructive feedback. We propose the reward for omission with confidence in knowledge (ROCK) format as an original formative assessment technique to help guide feedback associated with MCQs in an introductory undergraduate management science course. Our study contributes to theory by empirically showing that students can self‐assess their state of knowledge, signal it to the professor, and use proper answering options. In practice, ROCK is an easily implementable MCQ format that allows professors to gain information on student learning based on answers selected. ROCK identifies lack of knowledge or misinformation at both individual and collective levels thus providing opportunities for better feedback in class and during office hours. Limitations of the application of ROCK are also discussed.  相似文献

Abstract: With the persistence of microbiological foodborne illness and anticipated future shortage of scientists with agricultural and food science expertise in the United States, it is imperative to educate youth on microbiological food safety and enhance their awareness of opportunities to become engaged in finding solutions to food safety challenges. To help integrate food science education across the high school curriculum, new educational materials on microbiological food safety were developed and then disseminated to and evaluated by educators of secondary basic and applied sciences. The materials present food safety concepts in the context of foodborne illness outbreaks to introduce basic concepts of food microbiology, epidemiology, and food safety strategies as well as their broad impact on economics, communication, and regulations. The ready‐to‐implement educational materials support educational content standards and various learning styles and encourage critical thinking skills. The materials include a presentation on food microbiology and foodborne illness surveillance, case studies on foodborne illness outbreaks, a video on the laboratory investigation of foodborne illness, interactive web‐based activities, and supporting materials for teachers and classroom display. Exposure to the materials in a 1‐d workshop positively impacted educator familiarity with general microbiology, food safety strategies, regulatory requirements, and associated terminology as measured by a test administered prior to and after use of the materials. Teachers of biology, chemistry, family and consumer sciences, and related sciences rated the materials favorably on applicability, anticipated ease of implementation, and anticipated reception by students.  相似文献

Educators have increasingly implemented remedial education in elementary and secondary schools throughout Taiwan as a systemic approach toward closing achievement gaps. However, students from lower socioeconomic backgrounds and those in remote areas have shown little improvement in academic achievement. This issue raises the question of how educators are providing needed learning support to disadvantaged students in school and classroom settings. Thus, this study applies grounded theory to investigate teachers’ reactions to the remedial education policy in Taiwan, to have a reflective assessment on the policy, and to provide suggestions for policy implementation. The findings suggest that teachers’ responses to this government-imposed, centralized approach—classified as “cosmetic compliance,” “professional commitment,” and “try-out participation”—vary widely based on whether their ideological underpinnings are consistent with the government’s policy intent to close achievement gaps, and on whether they are equipped with professional knowledge and practical strategies to support the effective implementation of remedial education. Based on the findings, this study develops an interactive systemic model for more effectively implementing the remedial education policy, which illustrates a conceptualization that educational practitioners can hold professional autonomy while improving teaching and learning for low-achieving students.  相似文献
