Enhancing Student Learning in Food Engineering Using Computational Fluid Dynamics Simulations

Abstract: The current generation of students coming into food science and engineering programs is very visually oriented from their early experiences. To increase their interest in learning, new and visually appealing teaching materials need to be developed. Two diverse groups of students may be identified based on their math skills. Food science students tend to find it difficult to use mathematics as a problem‐solving tool for food engineering problems. Food engineering students, on the other hand, should be challenged to use emerging mathematical tools to develop their problem‐solving skills. Therefore, the approach of this project involved the development of a curriculum to train undergraduate food engineers in the effective use of computational fluid dynamics (CFD) software to solve food engineering problems by engaging them in the creation of food engineering teaching tools. These CFD outputs were then used as innovative teaching tools for the food science students. In this paper, this concept will be illustrated by unsteady‐state heat transfer and fluid flow problems. To evaluate the efficiency of the teaching materials developed, a student focus group was asked to answer the same quiz following a conventional and CFD output aided teaching session. The assessment result showed an improved understanding of the subject after the CFD teaching session. These visual aids were excellent tools to illustrate the validity of the formulas presented in class. In addition, the new visual materials enabled a better understanding of the relationships among different process parameters. In general, this helped the food science students better appreciate the food engineering concepts that govern food processing operations.     

佛名与忏仪——以张荣迁碑和陈海龙碑为中心

6世纪中国佛教忏仪流行甚广,以张荣迁碑和陈海龙碑为代表的造像碑就是最好的例证。考察发现,二碑所刻佛名分别来自《金光明经》、《法华经》和《大通方广忏悔灭罪庄严成佛经》。此文在铭文考释的基础上探讨了佛名与忏仪的关系。     

Exploring the reading–writing relationship in young Chinese language learners’ sentence writing

This study explored the concurrent and longitudinal relationships between reading and writing in young Chinese-as-a-second-language (CSL) learners’ sentence writing, using structural equation modeling. The participants comprised 126 Hong Kong senior primary ethnic minority students, whose literacy skills were assessed at two time points over the course of a year. In grade 5 (Time-1), they were assessed with Chinese character reading and reading comprehension measures to evaluate their reading ability. In grade 6 (Time-2), their sentence reading, sentence writing, and literacy component skills of Chinese character writing fluency and written syntactic skills were assessed. The results demonstrated that students’ reading and writing performances were substantially related both concurrently and longitudinally. Furthermore, (1) at Time-2, the component skills accounted for substantial portions of variance in sentence reading and writing skills, along with the relationship between them, while (2) Time-1 reading ability predicted Time-2 component skills and, through the mediation thereof, indirectly predicted sentence writing. Thus, in light of the linguistic characteristics of the Chinese language, literacy component skills are crucial component processes that connect reading and writing in CSL learners’ sentence writing.     

A Comparison of Video and Text-Based Questionnaire Methods for Testing Older Adults

Abstract

The purpose of this study was to initiate systematic research on dance as a creative and expressive art form. Although the process of expression through movement has concerned dancers and dance teachers for some time, there have been few attempts at a systematic analysis of either the process or the product of dance expression. Dance has generally been considered immeasurable because of its peculiarities as an art form.

While there is little apparent value in quantitative measurement of dance, qualitative measurement appears to have considerable value. It can sharpen the focus on principles of dance composition, contribute toward increased teaching effectiveness, enlarge dance's expressive range, and increase its ability to communicate.

Specifically, this study attempted to determine how effectively modern dance communicates by using a systematic analysis of individual dance compositions. Samples of dance studies with specific intentions were choreographed and filmed. The dances were then viewed and evaluated by a selected and trained jury on (a) their ability to communicate emotional and physical qualities, (b) the type and structure of their composition, and (c) their choreographic and artistic effectiveness.

Results of this study showed that least agreement was reached by the jurors in rating the dances according to structural strength and in identifying their composition type. Realistic vehicles of expression were more easily recognized than were abstract ones. There was substantial agreement on the emotion communicated by each composition. Presence of all the traditional dance elements appears unnecessary for effective communication.     

The Unexpected for the Expecting Parent: Effects of Disruptive Early Interactions on Mother–Infant Relationship

SYNOPSIS

High-quality parental caregiving promotes children’s development from their day of birth or even earlier. Whether there are ways to predict, and ultimately enhance, parental caregiving quality during the prenatal stages of development has been less well understood. This circumstance is even truer when things do not go according “to plan.” In this commentary, we explore two possible scenarios, perhaps unexpected for expectant parents, that can affect children’s development: (1) postpartum parental displays of atypical behaviors and parental caregiving strategies (i.e., maternal/paternal depression) and (2) postpartum child displays of atypical behaviors (i.e., autism spectrum disorder).     

Effects of learning styles on learners’ collaborative patterns in a mobile-assisted,Chinese character-forming game based on a flexible grouping approach

This paper reports a novel, mobile-assisted, game-based learning design for Chinese character learning. In playing the ‘Chinese-PP’ game in a 1:1 (one-device-per-student) setting, each of the 31 target students in Primary 3 (9 years old) is assigned a Chinese character component. A student may make use of his/her own and peers’ character components to form a legitimate Chinese character, and invite the peers with matching components to join his/her group. The intention is to assist the students in developing general orthographic awareness (understanding the structures of Chinese characters) through social negotiation. In this paper, the students’ collaborative learning processes in three game sessions were analysed. The relationships between students with varied learning styles and their game behaviours and learning gains were unveiled as a result. Through the Chinese-PP learning activities that stimulated active peer coaching and social learning, we found that all the target students became active learning participants and achieved high learning gains in the last game session. Recommendations for the future development of such a novel learning approach will also be given.     

Transformative Learning Through an Online Global Class Project in Teacher Education

This exploratory research study aimed to understand teacher candidates' experiences and perspectives in a global class project and to explore a way to develop global understanding in a teacher education program, by means of technology rather than study abroad. Using a qualitative approach, seven U.S. education majors were given opportunities to communicate online with teacher candidates in South Korea, while creating and discussing a concept map and movie presentation about “good teaching” on the Learning Management System. Results showed how the preservice teachers' global perspectives of education were developed through the project, and confirmed the significance of instrumental and communicative learning in transformative learning as well as direct communication and comparison with people from a different context using a carefully designed task-based course and immersive learning environment.
