This study addresses the development, dissemination, and assessment of a Food Safety System Management (FSSM) curriculum offered to college‐aged, agribusiness students in Yerevan, Armenia. Prior to beginning the program, demographic data were collected and a paper‐based pretest was administered to access the food safety knowledge, behavior, and attitude of participants (n = 29). For assessment of a skill, participants’ handwashing techniques were videotaped and scored before the program commenced. Immediately after completion of the entire curriculum, a paper‐based post‐test with identical questions for food safety knowledge, behavior, and attitude was administered and handwashing skills were assessed. ANOVA with repeated measures was used to evaluate significant differences (α = 0.05) for food safety knowledge using a pretest, post‐test, and a 3‐mo follow‐up. A paired t‐test was used to evaluate handwashing skills before and after the curriculum was presented. The pretest score (44.93%, ± 2.87) for food safety knowledge (n = 29) differed significantly (P <0.0001) when compared with the post‐test score (73.21%, ± 3.28) and the 3‐mo follow‐up (n = 23) score (67.76%, ± 3.93). Participants’ (n = 9) handwashing skills prior to delivery of the FSSM curriculum differed significantly (P <0.0001), when compared to handwashing skills after completion of the curriculum. Students’ food safety attitudes and behavior assessed using a five‐point Likert scale, also improved significantly as a result of the FSSM program. The 3‐mo follow‐up survey on food safety attitude and behavior was consistent with the post‐test survey results. The information from this project may be of interest to education experts, Extension professionals, food industry personnel, or regulatory agencies, in the development and dissemination of an international food safety program.  相似文献

A successfully targeted intervention can influence food safety knowledge, attitudes, and behaviors, as well as encourage participants to recognize their own responsibility for safe food handling. This acknowledgement of an individual's responsibility and capacity to address food safety can be understood as self‐efficacy of food safety (SEFS). This study investigated the impact of a specific educational intervention, Hands On: Real‐World Lessons for Middle School Classrooms, curriculum on SEFS in adolescents and was guided by two research questions: (1) to what extent can an existing food safety curriculum impact students’ SEFS, and (2) to what extent does a relationship exist between changes in self‐efficacy and changes in food safety behavior, particularly when controlling for knowledge gains. A total sample of 424 students across 6 states participated in this study. Teachers were trained to implement the Hands On program in their classrooms and then students were administered a pre‐ and posttest to measure the impact of the program on knowledge, food safety‐related behaviors, and SEFS. The data indicated that there is a strong predictive relationship between SEFS and positive behavior change. Additionally, the Hands On program was effective at increasing students’ SEFS.  相似文献

Climate change science is a challenging topic for student learning. This quantitative study examined the effectiveness of a geospatial curriculum approach to promote climate change science understandings in an urban school district with eighth-grade students and investigated whether teacher- and student-level factors accounted for students’ climate change knowledge achievement. The participants included 12 science teachers and 956 eighth-grade students. Data included a pre- and posttest climate change assessment measures for both teachers and students and a teacher measure of Geospatial Science-Technological Pedagogical Content Knowledge. Paired-sample t tests revealed statistically significant gains from pretest to posttest on their climate change knowledge (p < .001; effect sizes being large on multiple-choice items and medium on the open-ended response assessment). Both ordinary least squares (OLS) multiple regression and 2-level hierarchical linear modeling found that students’ initial climate change knowledge and gender were significant predictors for students’ posttest scores, p < .05. Students’ pretest scores were the strongest significant predictor of the posttest scores, p < .001. Neither the teachers’ climate change knowledge nor their Geospatial Science-Technological Pedagogical Content Knowledge had significant association with the students’ posttest scores. Teaching years was a significant predictor for students’ posttest scores in OLS regression (p < .001). The findings provide support that a geospatial curriculum approach is an effective science curriculum approach for learners in urban middle-level education.  相似文献

A potential method for teaching geospatial thinking and reasoning (GTR) is through geospatially enabled learning technologies. We developed an energy resources geospatial curriculum that included learning activities with geographic information systems and virtual globes. This study investigated how 13 urban middle school teachers implemented and varied the enactment of the curriculum with their students and investigated which teacher- and student-level factors accounted for students’ GTR posttest achievement. Data included biweekly implementation surveys from teachers and energy resources content and GTR pre- and posttest achievement measures from 1,049 students. Students significantly increased both their energy resources content knowledge and their GTR skills related to energy resources at the end of the curriculum enactment. Both multiple regression and hierarchical linear modeling found that students’ initial GTR abilities and gain in energy content knowledge were significantly explanatory variables for their geospatial achievement at the end of curriculum enactment, p < .001. Teacher enactment factors, including adherence to implementing the critical components of the curriculum or the number of years the teachers had taught the curriculum, did not have significant effects on students’ geospatial posttest achievement. The findings from this study provide support that learning with geospatially enabled learning technologies can support GTR with urban middle-level learners.  相似文献

ABSTRACT

The paper examines recent developments in food‐focused education following the implementation of the 1988 Education Reform Act. Drawing on data from an ESRC‐funded project on Teaching and Learning about Food and Nutrition in Schools (1993‐4), the paper explores evidence which demonstrates a marginalized and fragmented curriculum for food, and considers its implications. The paper comprises two sections. The first focuses on literature and curriculum documentation available at the start of the research and examines the formal corpus of school knowledge about food. This informs the second section which draws on data collected during case‐studies of four English secondary and primary schools and on what the data tell us about the food curriculum and its implications for transmission in the case‐study schools. Specific examples highlight issues of diversity, ambiguity and contradiction in implementation. Conclusions emphasize the need for greater curriculum coherence in policy and practice and for a reassessment of the framing and interpretation of food knowledge and skills. In the absence of systematic evaluations, schools continue to replicate rather than challenge the contradictions in understandings about food use which are documented features of the adult population in general.  相似文献

Ensuring teacher and speech and language pathology graduates are prepared to work collaboratively together to meet the diverse language literacy learning needs of children is an important goal. This study investigated the efficacy of a 3-h inter-professional education program focused on explicit instruction in the language skills that underpin early reading and spelling acquisition. The combined program incorporated student teachers and student speech and language pathologists (SLPs) working together on case-based instructional planning supplemented with structured opportunities for the groups to share their respective expertise in curriculum and linguistic knowledge. Student teachers (n = 18) and student SLPs (n = 27) were randomly assigned to this combined intervention or a comparison intervention that replaced the structured opportunities to share curriculum and linguistic knowledge with spending time together focused on non-language/literacy based activities. Before-and-after comparisons indicated that only the students in the combined condition increased their linguistic/curricular knowledge (p < 0.05). However, neither of the interventions improved students’ case-based instructional planning for children’s literacy learning over and above what they could achieve working individually. Implications for the pre-service preparation of teachers and SLPs are discussed.  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

The complexity of the material being taught in clinical neuroscience within the medical school curriculum requires creative pedagogies to teach medical students effectively. Many clinical teaching strategies have been developed and are well described to address these challenges. However, only a few have been evaluated to determine their impact on the performance of students studying clinical neuroscience. Interactive, 2‐hour, self‐directed small‐group interactive clinical case‐based learning sessions were conducted weekly for 4 weeks to integrate concepts learned in the corresponding didactic lectures. Students in the small groups analyzed cases of patients suffering from neurological disease that were based on eight learning objectives that allowed them to evaluate neuroanatomical data and clinical findings before presenting their case analysis to the larger group. Students’ performances on the formative quizzes and summative tests were compared to those of first‐year medical students in the previous year for whom the self‐directed, small‐group interactive clinical sessions were not available. There was a significant improvement in the summative performance of first‐year medical students with self‐directed clinical case learning in the second year (Y2) of teaching clinical neuroscience (P < 0.05) when compared with first‐year students in the first year (Y1) for whom the self‐directed learning approach was not available. Student performance in the formative assessments between Y1 and Y2 was not significantly different (P = 0.803). A target of ≥70% student scoring above 80% in the final summative examination was met. The current study revealed evidence for the impact and educational outcomes of a self‐directed, clinical teaching strategy in a clinical neuroscience curriculum for first‐year medical students.

Experimental intervention studies constitute the current dominant research designs in the autism education field. Such designs are based on a ‘knowledge‐transfer’ model of evidence‐based practice in which research is conducted by researchers, and is then ‘transferred’ to practitioners to enable them to implement evidence‐based interventions. While these research designs contribute important knowledge, they lead to a gap between what the research evidence may prescribe and what happens in practice, with a concomitant disparity between the priorities of researchers and practitioners. This paper discusses findings from the ESRC‐funded ‘SHAPE’ project, which adopted a different model of evidence‐based practice, focusing on knowledge co‐construction. Pupils (N = 8), teachers (N = 10), a speech and language therapist and a parent in three different school communities investigated creative ways in which children's social communication skills could be enhanced through technology use. Through a participatory methodology, digital stories were used as a method to enable engagement with the practical realities of the classroom and empower practitioners to construct and share their own authentic narratives. Participants articulated precise knowledge about the learning opportunities afforded to them and their pupils through quality interactions that were mediated by the technologies, as evidenced through digital stories. The SHAPE project shows that it is feasible to develop methodologies that enable genuine knowledge co‐construction with school practitioners, parents and pupils. Such co‐construction could offer realistic opportunities for pedagogical emancipation and innovation in evidence‐based practice as an alternative to the currently dominant and narrow model of knowledge transfer.  相似文献

ABSTRACT

Collaborative design positively affects both professional development and the implementation of curriculum change, because teachers develop competencies and practice and develop ownership of the change. The current study was aimed to explore what empirical evidence is available about processes that take place when teachers co-design and how these contribute to professional development and curriculum change. Evidence from 14 PhD studies was collected to study their impact on teacher learning and curriculum change, by analysing effects, mechanisms, and conditions. Results showed that effects of curriculum design teams, in terms of learning outcomes for teachers in areas such as (pedagogical) content knowledge and design knowledge and skills, became manifest in the outcomes of the curriculum design process, and in the appreciation by the stakeholders. We concluded that professional development, through collaborative design in teams, which is specific and linked to the curriculum, influences teachers’ knowledge and practice and impacts implementation of curriculum change.  相似文献

Even though teachers are key figures of a program's effectiveness, most intervention studies have not focused explicitly on the effects of antibullying programs at teacher level. We conducted a meta‐analysis into the effects of school‐based antibullying programs on determinants of teacher intervention, including teachers’ attitudes towards bullying, their self‐efficacy and knowledge regarding intervention strategies, and the effects on teachers’ bullying intervention itself. Following the PRISMA guidelines, 13 peer‐reviewed papers were retrieved that reported outcomes on teachers, staff, and students (N = 948, 2,471, and 138,311, respectively). Antibullying programs had a significant moderate effect on determinants of teacher intervention (g = 0.531) and a significant small to moderate effect on teacher intervention in bullying situations (g = 0.390). Results of the meta‐analysis indicate that the effectiveness of antibullying programs may increase when components are included to reinforce teachers’ attitudes, subjective norms, self‐efficacy, knowledge, and skills towards reducing bullying in the school.  相似文献

Clinically integrated curricula in health science education has been shown to promote the development of problem-solving schema and positively impact knowledge acquisition. Despite its’ purported benefits, this type of curricula can impose a high cognitive load, which may negatively impact novice learners’ knowledge acquisition and problem-solving schema development. Introducing explicit clinical reasoning instruction within pre-professional undergraduate basic science courses may limit factors that increase cognitive load, enhance knowledge acquisition, and foster developing clinical problem-solving skills. This study, conducted over the Fall and Spring semesters of the 2018–2019 school year, sought to evaluate whether the implementation of a clinical reasoning instructional intervention within a clinically integrated pre-professional undergraduate general human anatomy course influenced students’ acquisition of anatomical knowledge and development of clinical problem-solving skills. Results of the study were mixed regarding the acquisition of anatomical knowledge. Both the intervention and comparison groups performed similarly on multiple choice examinations of anatomical knowledge. However, the clinical reasoning intervention positively impacted students’ ability to apply clinical reasoning skills to anatomically based clinical case studies. Results from M\mixed between-within subjects analysis of variance comparing scores on Written Clinical Reasoning Assessments revealed a significant interaction between time and group affiliation, with the groups receiving the interventions outperforming the comparison groups: Fall, P < 0.001; Spring, P < 0.001. The results of this study may imply that explicit clinical reasoning instruction within a clinically integrated undergraduate Human Anatomy course could hold potential for fostering students’ early clinical reasoning skills.  相似文献

Masculinity ideology is argued to be associated with academic outcomes. However, relatively few studies have examined these associations. This study examines the associations between masculinity ideology and academic skepticism, self‐presentation of low achievement, academic engagement, academic initiative, and self‐regulation, above and beyond academic self‐efficacy, among a diverse sample of urban youth. With a sample of 135 eighth‐grade students from a Northeastern middle school, 5 separate multiple hierarchical regression analyses were used to examine whether students’ endorsement of masculinity ideology predicted the criterion variables above and beyond academic self‐efficacy. The sample was comprised of 54 girls and 74 boys ages 12–14 years (M = 13.14; SD = .37). Results showed academic self‐efficacy significantly predicted academic engagement (B = 1.26; β = .53, p < .001; f2 = .39), academic initiative (B = .98; β = .37; p < .001, f2 = .16), and behavioral regulation (B = .61; β = .24; p < .05; f2 = .09) and explained an additional 8 and 10% of the variance in self‐presentation of low achievement (B = .54; β = .33; p = .001; f2 = .14) and academic skepticism (B = .56; β = .35; p < .001; f2 = .15), respectively, over and above academic self‐efficacy. Gender, which was dummy coded and entered as a covariate, only predicted self‐presentation of low achievement. Findings from this study point to the need to foster positive academic outcomes through bolstering academic self‐efficacy and, perhaps more important, addressing masculinity ideology.  相似文献

Distance learning has evolved over many generations into its newest form of what we commonly label as online learning. In this second-order meta-analysis, we analyze 19 first-order meta-analyses to examine the impact of distance learning and the special case of online learning on students’ cognitive, affective and behavioral outcomes. We examine to what extent distance learning generation level, and instructional setting moderate the influences of distance learning on cognitive, affective and behavioral outcomes. This second-order meta-analyses also analyzes the first-order meta-analyses for methodological quality and robustness. The findings revealed a statistically significant overall average effect size (g = 0.156, p < .001 with a 95% confidence interval of 0.087–0.224) of distance learning impacting cognitive, affective and behavioral outcomes in comparison to face-to-face learning. Meta-analyses on higher education had a statistically significant larger effect size than K-12 education. Limitations, implications, and directions for future research are discussed.  相似文献

This article describes the Parent Teacher Education Curriculum, a Web-based curriculum focused on instructing teachers about best practices in family involvement and assesses its impact on the knowledge and attitudes of preservice teachers related to family involvement. Pre- and post-measures of preservice teacher candidate knowledge of and attitude toward parent involvement were analyzed using multivariate analysis of variance (MANOVA) and paired-samples t-tests. Findings revealed a significant multivariate main effect for the time of knowledge assessment administration (pre vs. post): Wilks' λ = .613, F(6, 449) = 47.308, p < .001, partial eta squared = .387. This suggested that overall Knowledge increased significantly from pre- to post-administration. In addition, multivariate analysis for the time of attitude assessment administration (pre vs. post) was Wilks' λ = .982, F(3, 1548) = 9.65, p <. 001, partial eta squared = .018. This suggested that overall Attitude increased significantly from pre- to post-administration.  相似文献

This research compares the industry readiness, product development skill level, and overall knowledge gains of students taking an undergraduate research course (treatment) to those who did not (control). This 2‐semester Applied Interdisciplinary Product Development (AIPD) course for sophomores brought together interdisciplinary teams of food science, nutrition, and packaging science students in a hands‐on setting to create healthy food products for children, complete with retail packaging. A Subject Knowledge Assessment (SKA) was used to evaluate the mean percent difference value (MPDV) of food science, nutrition, packaging science, and general product development knowledge gained through the course. SKA results indicated that the MPDV were significantly different (α = 0.05) between the treatment and comparison groups in the overall score and in every subject area score except packaging science. Data from an Exit Questionnaire (EQ) was used for evaluation of attitudes pertaining to product development knowledge and skills, department engagement, and pedagogy. EQ results indicated that mean scores between the treatment and comparison groups were significantly different (α = 0.05) in 7 of the 9 statements on product development knowledge and skills, both statements pertaining to pedagogy, and the statement pertaining to department engagement. Overall, the research project was considered a successful intervention for educating sophomores at the University. Overall, the research project was considered a successful intervention for educating sophomores in the Food, Nutrition and Packaging Science department at Clemson University. The student‐lead teams were held to a greater degree of accountability for their success in terms of education gleaned and value of experience gained as metric for the University and other IFT Accredited programs.  相似文献

A teacher professional development program for in-service elementary school science teachers, the Rice Elementary Model Science Lab (REMSL), was developed for urban school districts serving predominately high-poverty, high-minority students. Teachers with diverse skills and science capacities came together in Professional Learning Communities, one full day each week throughout an academic year, to create a classroom culture for science instruction. Approximately 80 teachers each year received professional development in science content and pedagogy using the same inquiry-based constructivist methods that the teachers were expected to use in their classrooms. During this four-year study, scientists and educators worked with elementary teachers in a year-long model science lab environment to provide science content and science pedagogy. The effectiveness of the program was measured using a mix of quantitative and qualitative methods that allowed the researchers to triangulate the findings from quantitative measures, such as content test and surveys, with the emerging themes from the qualitative instruments, such as class observations and participant interviews. Results showed that, in all four years, teachers from the REMSL Treatment group have significantly increased their science content knowledge (p?<?0.05). During the last two years, their gains in science content knowledge, use of inquiry-based instruction and leadership skills were significantly higher than those of the Control group teachers' (p?<?0.01, p?<?0.001 and p?<?0.05, respectively). Three themes resonated in the interviews with participants: science content knowledge growth, constructivist pedagogy and leadership skills.  相似文献

Schools support teachers in their professional learning, just as teachers support students in their learning. To accomplish this, schools can provide support systems that enhance teachers’ knowledge, comfort, and instructional skills. This study examined the impact of two district-provided supports (curriculum and professional development) on sexual health instruction among middle and high school health education teachers. Data were abstracted and analyzed using inductive coding from 24 teacher interviews (2015–2016). Findings illustrate outcomes from both curriculum and PD on teachers’ self-reported knowledge, comfort, and skills. The district-provided supports appeared to contribute to improved teachers’ self-efficacy in delivering sexual health education.  相似文献

Writing is a critical skill for success in all areas of life, but it is one of the least taught skills in school. Teachers consistently report being unprepared to teach writing. In this study, set in a Southern U.S. boomtown, teachers received two days of practice-based professional development for a ten-week implementation of self-regulated strategy development (SRSD), an evidence-based writing intervention, to support student persuasive and informational writing as well as performance on the state standardized writing exam. This multi-site cluster randomized controlled study evaluated the effectiveness of SRSD on student writing outcomes including prompt adherence, elements, and holistic quality. Multilevel modeling analysis was used to evaluate data from 418 fourth -grade students (256 treatment, 162 control) nested across 33 classes (n = 17 treatment taught by 8 departmentalized teachers; 16 control, 9 departmentalized teachers) within 11 schools randomly assigned to condition. Teachers implemented SRSD with high fidelity (M = 92%; range 91–100%). SRSD had a statistically significant and large effect on prompt adherence (p < .001; Hedges’ g = 1.87), elements (p < .001; Hedges’ g = 0.84) and holistic scores (p < .001; Hedges’ g = 0.87), while holding gender and pretest scores constant. Effects of SRSD on all writing measures were not significantly moderated by students’ gender, students’ pretest scores, or schools’ pretest scores. There were complications with teacher observations, especially related to technology. Limitations and future directions are discussed.  相似文献

To understand how students learn about science controversy, this study examines students' reasoning about tradeoffs in the context of a technology‐enhanced curriculum about genetically modified food. The curriculum was designed and refined based on the Scaffolded Knowledge Integration Framework to help students sort and integrate their initial ideas and those presented in the curriculum. Pre‐test and post‐test scores from 190 students show that students made significant (p?<?0.0001) gains in their understanding of the genetically modified food controversy. Analyses of students' final papers, in which they took and defended a position on what type of agricultural practice should be used in their geographical region, showed that students were able to provide evidence both for and against their positions, but were less explicit about how they weighed these tradeoffs. These results provide important insights into students' thinking and have implications for curricular design.  相似文献
