Understanding the role of food science education in developing undergraduate students’ intentions to implement Good Manufacturing Practices (GMPs) may be a key strategy in developing the workforce's implementation of GMPs and other food safety programs. Previous research has demonstrated the effects of educational interventions on planned food safety behaviors in various settings; however, none have studied GMPs interventions and college students. This study applied the Theory of Planned Behavior (TPB) to evaluate the effects of a game‐based e‐learning module on undergraduate students’ planned behaviors concerning GMPs. Forty‐four participants were recruited from 42 food science clubs across the United States to complete a game‐based e‐learning module and pre‐ and posttest survey instruments. We compared changes in pre‐ and posttest scores using paired Wilcoxon signed rank tests and explored the role of GMP‐related knowledge and TPB constructs (attitudes, subjective norms, and perceived behavioral controls) in predicting students’ intentions to implement GMPs using multiple linear regression. We modeled pretest scores, posttest scores, and changes in scores while controlling for student demographic factors (for example, year in college, gender, and so on). Only participants’ knowledge and perceived behavioral controls significantly increased (P < 0.05) after completing the game‐based e‐learning module. Posttest regression models explained twice as much variance than pretest models (up to 54% total). Changes in intentions to implement GMPs were predicted by changes in subjective norms, perceived behavioral controls, and knowledge, as well as previous enrollment in food safety courses and interest in working in the food industry. The only predictive variables for both pre‐ and posttest scores were subjective norms, previous enrollment in food safety courses and interest in working in the food industry (P < 0.05). A discussion of how these results provide insights for food safety educators to optimize their teaching impacts was presented.  相似文献

Abstract

This article discusses the design, development, and implementation of a collaborative learning environment for online training ‘Infoshare on the Web’ It was designed to teach participants how to use and/or improve their use of Web search engines to access information on the Web. Participants collaborated in completing group tasks using asynchronous communication provided by Simon Fraser's Virtual‐U, a Web‐based environment that supports distance education, information sharing, and training. The module was delivered in four weeks, and participants found both advantages and limitations in the use of asynchronous environments for training.  相似文献

Driven by claims of efficacy, flexibility and resource effectiveness, higher education is increasingly utilising the Web as an instructional tool. The claims for pedagogical effectiveness are often just that – claims — and appear not to have been proven in the reality of subject presentation and evaluation. Thus, it is necessary to examine assumptions regarding the benefits of Web‐based instruction in terms of effectiveness. This article discusses aspects of an investigation which examined and compared the effectiveness of HIV/AIDS related collaborative tutorial activities carried out in both a Web‐based learning environment and a face‐to‐face class situation within an undergraduate health education subject. Effectiveness of the pedagogical strategy and the different learning environments were measured in terms of observed learning outcomes and reported perceptions of the learners regarding their learning experience. Preliminary results based on measured learning outcomes related to the subject matter, HIV/AIDS, demonstrated that collaborative learning activities were significantly more effective in the Web‐based than in the class environment. Additionally, the vast majority of learners perceived the Web‐based environment to be as effective or more effective than the face‐to‐face, class environment in terms of facilitating their understanding of the issues explored in the subject.  相似文献

This research investigated the possible impacts of computers on Turkish fourth‐grade students’ geometry scores and further geometric learning. The study used a pretest–intervention–posttest experimental design. Results showed that students who did not have computers at home initially had lower geometry scores. However, these differences were minimised with an appropriate intervention containing computer‐based Tangram puzzles. This suggests that at schools, it seems more effective to integrate mathematical content and technology in a manner that enables students to do playful mathematical discoveries.  相似文献

Understanding safe food practice is important for home‐based food operators to prevent foodborne illness. Earlier work has found that home‐based food operators lack food safety knowledge and may benefit from training that is specifically tailored to their needs. Unfortunately, home‐based food operators may be deterred from enrolling in traditional educational formats due to their busy schedules. The objective of this study was to pilot and evaluate the effectiveness of an online food safety education module for home‐based food operators in Iowa through three learning assessments. Twenty‐one participants enrolled in a blended workshop in which participants completed one online module before attending a face‐to‐face session where they completed the remaining five modules. The effectiveness of the online module was measured by examining the first‐attempt average scores on learning assessments, the number of assessment attempts required to achieve 100%, and the first‐attempt performance by question type. The three learning assessment tools resulted in first‐attempt averages of approximately 86%, 90%, and 83%, surpassing our standard of effectiveness of 75% and showing good potential for the online format. The learning assessment attempt numbers of 4.65, 1.67, and 3.81 showed difficulty with knowledge transfer for some topics. Comprehension and analysis‐style questions had first‐attempt success rates of approximately 85% and 88%, respectively. Scores on knowledge and application‐style questions were lower with first‐attempt success rates of approximately 80% and 75%, respectively. These findings were used to improve the first online module and guide the transition of the remaining five modules to the online format.  相似文献

Self-assessment and task-selection skills are crucial in self-regulated learning situations in which students can choose their own tasks. Prior research suggested that training with video modeling examples, in which another person (the model) demonstrates and explains the cyclical process of problem-solving task performance, self-assessment, and task-selection, is effective for improving adolescents’ problem-solving posttest performance after self-regulated learning. In these examples, the models used a specific task-selection algorithm in which perceived mental effort and self-assessed performance scores were combined to determine the complexity and support level of the next task, selected from a task database. In the present study we aimed to replicate prior findings and to investigate whether transfer of task-selection skills would be facilitated even more by a more general, heuristic task-selection training than the task-specific algorithm. Transfer of task-selection skills was assessed by having students select a new task in another domain for a fictitious peer student. Results showed that both heuristic and algorithmic training of self-assessment and task-selection skills improved problem-solving posttest performance after a self-regulated learning phase, as well as transfer of task-selection skills. Heuristic training was not more effective for transfer than algorithmic training. These findings show that example-based self-assessment and task-selection training can be an effective and relatively easy to implement method for improving students’ self-regulated learning outcomes. Importantly, our data suggest that the effect on task-selection skills may transfer beyond the trained tasks, although future research should establish whether this also applies when trained students perform novel tasks themselves.  相似文献

Although researchers in undergraduate science, technology, engineering, and mathematics education are currently using several methods to analyze learning gains from pre- and posttest data, the most commonly used approaches have significant shortcomings. Chief among these is the inability to distinguish whether differences in learning gains are due to the effect of an instructional intervention or to differences in student characteristics when students cannot be assigned to control and treatment groups at random. Using pre- and posttest scores from an introductory biology course, we illustrate how the methods currently in wide use can lead to erroneous conclusions, and how multiple linear regression offers an effective framework for distinguishing the impact of an instructional intervention from the impact of student characteristics on test score gains. In general, we recommend that researchers always use student-level regression models that control for possible differences in student ability and preparation to estimate the effect of any nonrandomized instructional intervention on student performance.  相似文献

Minimal evidence exists regarding the retrospective pretest’s effectiveness as a tool to obtain usable, indirect evidence of student learning in open admissions institutions. The researcher conducted this study to determine if a retrospective pretest more accurately detected a change in students’ knowledge compared to a conventional pretest–posttest. The researcher designed a 17‐item inventory covering course objectives, and students were randomly assigned to either a retrospective pretest (referred to as post‐then) or a conventional pretest–posttest group. Findings indicated that participants in the post‐then group reported a greater change in knowledge compared to the conventional group. This finding supported the use of the retrospective pretest as a tool for getting usable, indirect evidence of student learning. Future research needs to examine response effect, alternative ways of calculating treatment effect and the confounding influences of other perceptual variables.  相似文献

Modernizing classroom pedagogical practice requires openness to revisiting previously held assumptions and theories about what constitutes authentic teaching/learning cycles. The ever‐growing gap between the number of stimuli that students are exposed to and their available attentional resources indicates that sustained attention may have increasing value transitioning into 21st‐century learning environments requiring self‐reflection, collaborative learning, and self‐directed decision‐making. Neurofeedback has shown promise in laboratory and clinical settings as a tool for building sustained attention, but little in situ research has been completed in bringing the technology into the school for empirical testing. Furthermore, attentional research lacks connections between neural network modeling and observable neuromarkers for attention. This article aims to bridge these distinct concepts to support an understanding of the potential impacts of neurofeedback training (NT) and to provide a framework for other Mind, Brain, and Education researchers planning in situ NT studies.  相似文献

A shared document‐based annotation tool was presented, and its usefulness in two different real‐life web‐based university‐level courses (adult learners, n= 27 and adolescent learners, n= 23) was empirically investigated. The study design embodied three data collection phases: (1) a pretest measuring self‐rated motivation, learning strategies, and social ability; (2) log file data analysis showing actual use of the system features; and (3) a posttest in a form of an email survey. For both groups, the results showed that the level of motivation has a positive effect on activity in the system and the final grade. The learners, who reported to have good time‐management strategies, were the most active users of the system. The level of social ability predicted both the number of consecutive comments in the documents and the threads in document‐related newsgroup discussions. Log file data analysis showed that user activity in the system was positively related to the final grade in both samples. Results of the posttest showed that all the respondents agreed when asked: (1) if the system brought added value to the learning process; (2) if the use of the system changed their studying habits favourably; and (3) if they would like to use the system in other courses.  相似文献

The rise in interactive digital media has catapulted faculty‐student contact abilities from the traditional Web 1.0 model to a post‐Web 2.0 world where students and faculty can have much more interaction in classroom exchanges. Since business cases have long been a pedagogy of choice among professors concerned with training the next generation of decision makers, the intent of this exploratory teaching execution was to gain insight into the case teaching experience in Second Life (SL). SL is a virtual world developed by Linden Lab that enables its users to interact with each other through avatars (virtual representations of the self). While online classrooms in SL are not new (a number of universities throughout the world have set up virtual campuses), business education scholarship is lacking as related to the use of virtual worlds for educational purposes. The aim of the execution was not to suggest that SL case teaching should displace the traditional case classroom interactions. Rather, the exercise found that a case‐based class can be held and attended independent of time, distance, and location should the need arise. Case teaching in SL offers an availability alternative or supplement to the traditional case teaching and learning approach.  相似文献

The cheap and powerful personal computer (PC) has become an important and efficient tool for supporting engineering education. In this paper a PC‐based training module, AIROBOT,is presented. The purpose of this module is to provide a platform for students to develop and experiment with artificial intelligence techniques.

The training module, AIROBOT,utilizes an electronic noughts and crosses game board which is interfaced to the Scorbot‐ER VII robot and a PC. The development and implementation of the module are discussed. Two techniques developed by the students are presented to illustrate the utilization of the module. The first technique involves searching a game tree data structure. The learning involves the on‐line generation of the game tree as the games are played. An evaluation function is used to facilitate the search. The other technique is based on the artificial neural network approach using the backpropagation paradigm. The structure of the neural networks, training and performances are presented. The PC‐based training module has the potential to enhance the student understanding through the practical application of artificial intelligence. It is envisaged that similar modules can be easily integrated into most engineering undergraduate robotics courses.  相似文献

We argue that a focus on building an authoring tool for a complete learning environment is misplaced. An analysis of the task of authoring a commercial educational system reveals it to be best accomplished through authoring separate components. For many of these components, authoring tools already exist and need not be duplicated for use in educational systems. Connecting the various components together is a separate authoring task, and parts of this task are different for educational systems than for typical component-based software. The second half of this article describes the Visual Translator, an authoring tool we have written specifically for this purpose.  相似文献

Web‐based education is a popular format for the delivery of college courses. Research has shown that it may not be the best form of education for all students. Today, many students (and student advisors) face a choice in course delivery format (i.e., Web‐based or more traditional classroom courses). This research study examines the relationship between student personality characteristics and their achievement scores as a means of identifying predictors of academic success in an undergraduate business program using Web‐based education. The results of the study show that four basic personality characteristics are highly correlated to student achievement in Web‐based courses. Use of these personality characteristics as variables in a regression model is shown to be a highly accurate predictive tool to aid students in the decision as to whether to take a particular Web‐based course format or a more traditional classroom course.  相似文献

Colour is a common feature in computer‐aided learning (CAL), though the instructional effects of screen colour are not well understood. This investigation considers the effects of different CAL study tasks with feedback on posttest performance and on posttest memory of the lesson colour scheme. Graduate students (n=68) completed a computer‐based vocabulary lesson that included either multiple‐choice or constructed‐response study tasks with feedback. Each lesson section used a different colour theme, while the posttest did not use colour. The constructed‐response study task was a little more effective for posttest memory of lesson content but was substantially less effective for posttest memory of the lesson colour scheme. These results show a clear interaction of screen colour and lesson study task, a memory‐context effect. The practical and theoretical implications of these findings are discussed.  相似文献

This study examines middle school students’ learning and motivation as they engaged in a new media enriched problem-based learning (PBL) environment for middle school science. Using a mixed-method design with both quantitative and qualitative data, we investigated the effect of a new media environment on sixth graders’ science learning, their motivation, and the relationship between students’ motivation and their science learning. The analysis of the results showed that: Students significantly increased their science knowledge from pretest to posttest after using the PBL program, they were motivated and enjoyed the experience, and a significant positive relationship was found between students’ motivation scores and their science knowledge posttest scores. Findings were discussed within the research framework.  相似文献

ABSTRACT

This article reports on an intervention study into the effects of a training in the use of social and cognitive strategies on the learning outcomes of students in secondary mathematics education. Special attention is given to differential effects for high‐ and low‐achieving students. The focus on differential effects is derived from studies into learning in small co‐operative groups, and from the results of meta‐analyses into the effects of training in learning strategies. From these studies it can be concluded that in general such programs contribute to learning. However, it seems that low‐achieving students are unable to benefit from interventions of the kind investigated (i.e., co‐operative learning and training in learning strategies). The main question is whether it is possible to design an instructional program from which all students benefit, and from which the low‐achieving students profit more than their counterparts in the control‐program. In the present study three instructional programs for co‐operative learning were compared: (i) an experimental program with special instruction in the use of social strategies; (ii) an experimental program with special instruction in the use of cognitive strategies; and (iii) a control program without training in either cognitive or social strategies. The programs were identical with respect to mathematical content and general instructional settings (a combination of whole‐class instruction, working in co‐operative groups and individual work). The experiment addressed the following research question: what are the general and differential effects of a training in the use of social and cognitive strategies on the results of learning in secondary mathematics? The research was conducted in two schools for secondary education in a total of 21 classes, involving a total of 511 students. The design was a pretest‐posttest control group design, using two experimental groups and one control group. The data were analysed from a multi‐level perspective. The outcomes of the investigation clearly show the effects of the intervention. Teaching cognitive and social strategies has the expected, positive effects. In addition to this main effect, a compensatory effect for the low‐achieving students was found. The low‐achieving students in the experimental conditions outperformed their counterparts in the control group.

Many authoring tools have been proposed in an attempt to find more effective ways to face the challenge of developing educational software. However, most of them are reported to be restrictive, since they are strongly connected to a specific educational software development methodology. The AIDA (Ambiente Integrado para o Desenvolvimento de Aplicações educacionais) authoring environment was developed at the University of Coimbra having as its main objectives the support of most of the activities involved in authoring and making educational software development easier. The AIDA system is based on a design module, i.e. a prototyping tool allowing the creation of Windows-based software, including multimedia features. The system assists evaluation activities and it caters also for support on translation and cultural adaptation, as well as on the reutilization of educational materials. The use of the AIDA environment is illustrated by three small examples using different development methodologies.  相似文献

The purpose of this project was to develop Web‐based learning modules that combine (1) animated 3D graphics; (2) 3D models that a student can manipulate independently; (3) passage of time in embryonic development; and (4) animated 2D graphics, including 2D cross‐sections that represent different “slices” of the embryo, and animate in parallel. These elements were presented in two tutorials, one depicting embryonic folding and the other showing development of the nervous system after neural tube formation. The goal was to enhance the traditional teaching format—lecture combined with printed diagrams, text, and existing computer animations—with customized, guided, Web‐based learning modules that surpassed existing resources. To assess module effectiveness, we compared quiz performance of control groups who attended lecture and did not use a supporting module, with study groups who used a module in addition to attending lecture. We also assessed our students' long‐term retention of the material, comparing classes who had used the module with students from a previous year that had not seen the module. Our data analysis suggests that students who used a module performed better than those given only traditional resources if they used the module after they were already somewhat familiar with the material. The findings suggest that our modules—and possibly computer‐assisted‐instruction modules in general—are more useful if used toward the later stages of learning, rather than as an initial resource. Furthermore, our data suggest that the animation aids in long‐term retention. Both medical students at the University of Cincinnati and medical faculty from across the country commented favorably on their experiences with the embryonic development modules.

Although Intelligent Tutoring Systems (ITSs), also called knowledge-based tutors, are becoming more common and proving to be increasingly effective, each one must still be built from scratch at a significant cost. At the University of Massachusetts, Amherst, we have developed domain independent tools for authoring all aspects of a knowledge-based tutor: the domain model, the teaching strategies, the student model, and the learning environment. In this article, I describe these tools, discuss a number of design issues and design tradeoffs that are involved in building ITS authoring tools, and discuss knowledge acquisition and representation issues encountered in my work. I also describe how we plan to use these tools (collectively called Eon), including ontology objects, as a meta-authoring tool for designing special-purpose authoring tools tailored for specific domain types.  相似文献
