The use of specially designed tasks to enhance student interest in the cadaver dissection laboratory     

Kang SH  Shin JS  Hwang YI 《Anatomical sciences education》2012,5(2):76-82

Cadaver dissection is a key component of anatomy education. Unfortunately, students sometimes regard the process of dissection as uninteresting or stressful. To make laboratory time more interesting and to encourage discussion and collaborative learning among medical students, specially designed tasks were assigned to students throughout dissection. Student response and the effects of the tasks on examination scores were analyzed. The subjects of this study were 154 medical students who attended the dissection laboratory in 2009. Four tasks were given to teams of seven to eight students over the course of 2 weeks of lower limb dissection. The tasks were designed such that the answers could not be obtained by referencing books or searching the Internet, but rather through careful observation of the cadavers and discussion among team members. Questionnaires were administered. The majority of students agreed that the tasks were interesting (68.0%), encouraged team discussion (76.8%), and facilitated their understanding of anatomy (72.8%). However, they did not prefer that additional tasks be assigned during the other laboratory sessions. When examination scores of those who responded positively were compared with those who responded neutrally or negatively, no statistically significant differences could be found. In conclusion, the specially designed tasks assigned to students in the cadaver dissection laboratory encouraged team discussion and collaborative learning, and thereby generated interest in laboratory work. However, knowledge acquisition was not improved.  相似文献   

A Novice-Expert Study of Modeling Skills and Knowledge Structures about Air Quality     

Ying-Shao Hsu  Li-Fen Lin  Hsin-Kai Wu  Dai-Ying Lee  Fu-Kwun Hwang 《Journal of Science Education and Technology》2012,21(5):588-606

This study compared modeling skills and knowledge structures of four groups as seen in their understanding of air quality. The four groups were: experts (atmospheric scientists), intermediates (upper-level graduate students in a different field), advanced novices (talented 11th and 12th graders), and novices (10th graders). It was found that when the levels of modeling skills were measured, for most skills there was a gradual increase across the spectrum from the novices to the advanced novices to the intermediates to the experts. The study found the experts used model-based reasoning, the intermediates and advanced novices used relation-based reasoning, and the novices used phenomena-based reasoning to anticipate conclusions. The experts and intermediates used more bi-variable relationships in experimental design and anticipated conclusions, but used more multiple-variable relationships in identifying relationships. By contrast, the advanced novices and novices mostly used bi-variable relationships in all modeling skills. Based on these findings, we suggest design principles for model-based teaching and learning such as designing learning activities to encourage model-based reasoning, scaffolding one??s modeling with multiple representations, testing models in authentic situations, and nurturing domain-specific knowledge during modeling.  相似文献   

Using Blackboard and Skype for Mentoring Beginning Teachers     

Young Suk Hwang  Konstantinos Vrongistinos 《The American journal of distance education》2013,27(3):172-179

Abstract

The purpose of this article is to examine the nature of the Blackboard and Skype-based electronic mentoring system for beginning teachers. The Quality Teachers for Quality Students project developed an electronic mentoring system between beginning teachers and experienced teachers to support beginning teachers' instructional and classroom management skills with regard to the unique needs of English language learners (ELLs) in Southern California. The data analysis indicated that the combination of using Blackboard and Skype tools was beneficial to beginning teachers' effective teaching of ELLs.  相似文献   

The effect of an MSN agent on learning community and achievement     

Wu-Yuin Hwang  Sheng-Yi Wu 《Interactive Learning Environments》2013,21(4):413-432

The use of instant messaging to support e-learning will continue to gain importance because of its speed, effectiveness, and low cost. This study developed an MSN agent to mediate and facilitate students' learning in a Web-based course. The students' acceptance of the MSN agent and its effect on learning community identification and learning achievement were investigated using the technology acceptance model. Results indicated that the MSN agent proved easy to use, and that students recognized its benefits with regard to their learning. In more detail, students perceived that the MSN agent would be beneficial to learning community identification, but this perceived usefulness had less effect on their learning achievement. However, it was found that perceived system usage of the MSN agent was significantly related to learning achievement, which differed from the result of analyzing students' perceived usefulness of the agent. Rather than using a systematic recording log, the perceived system usage of the MSN agent was measured through questionnaires. Interview feedback revealed that effective learning was related to the learners' engagement in the MSN agent and not just from their perceived usefulness of it. Therefore, the MSN agent could have more potential to facilitate students' learning in an online environment if learning activities related to study are designed to promote students' engagement.  相似文献   

Social and Evolutionary Explanations for Face-ism: Facial Prominence in Female Academic Profile Pictures     

Glenna L. Read  Rachelle L. Pavelko  Hansol Hwang 《Communication Research Reports》2017,34(2):98-105

Face-ism describes a phenomenon in which men are presented with more facial prominence in images than are women. Previous theorists have ascribed this phenomenon to social causes. However, occurrence of face-ism across historical and cultural contexts suggests the possibility of biological influence. The current study aimed to explore face-ism through the intersection of social influence and biological factors via the investigation of photographs of women of different ages and social standing within the context of academia. Results show that graduate students displayed the face less prominently than both tenured and nontenured faculty. Additionally, younger women displayed the face less prominently than older women.  相似文献   

Key Authors in Business and Management Education Research: Productivity,Topics, and Future Directions          下载免费PDF全文

Previous studies of author productivity in business and management education (BME) research have focused on single disciplinary areas, and even single journals. This study is the first to examine the productivity of BME scholars across multiple disciplinary areas (i.e., accounting, economics, finance, information systems, management, marketing, and operations/supply chain management). We analyzed a pool of 17 BME journals with the highest hg‐index, by including the top three journals in the accounting and information systems areas, the top two journals in each of the other disciplinary areas, and an interdisciplinary BME journal. This examination covered a 10‐year period (2005‐2014), 4,464 articles and 9,617 article co‐authors. We identified 7,209 unique authors in this pool and ranked their productivity to create a “Key Authors” list. Each of the top 99 authors had five or more articles in our database. Our findings indicate the potential for cross‐disciplinary dissemination of research ideas and opportunities for scholars to enhance their research profile, because even a small increase in productivity can lead to substantial movement in the BME rankings of authors.  相似文献   

Climbing Bloom's taxonomy pyramid: Lessons from a graduate histology course          下载免费PDF全文

Nikki B. Zaidi  Charles Hwang  Sara Scott  Stefanie Stallard  Joel Purkiss  Michael Hortsch 《Anatomical sciences education》2017,10(5):456-464

Bloom's taxonomy was adopted to create a subject‐specific scoring tool for histology multiple‐choice questions (MCQs). This Bloom's Taxonomy Histology Tool (BTHT) was used to analyze teacher‐ and student‐generated quiz and examination questions from a graduate level histology course. Multiple‐choice questions using histological images were generally assigned a higher BTHT level than simple text questions. The type of microscopy technique (light or electron microscopy) used for these image‐based questions did not result in any significant differences in their Bloom's taxonomy scores. The BTHT levels for teacher‐generated MCQs correlated positively with higher discrimination indices and inversely with the percent of students answering these questions correctly (difficulty index), suggesting that higher‐level Bloom's taxonomy questions differentiate well between higher‐ and lower‐performing students. When examining BTHT scores for MCQs that were written by students in a Multiple‐Choice Item Development Assignment (MCIDA) there was no significant correlation between these scores and the students' ability to answer teacher‐generated MCQs. This suggests that the ability to answer histology MCQs relies on a different skill set than the aptitude to construct higher‐level Bloom's taxonomy questions. However, students significantly improved their average BTHT scores from the midterm to the final MCIDA task, which indicates that practice, experience and feedback increased their MCQ writing proficiency.

How students with autism spectrum conditions understand traditional bullying and cyberbullying     

Yoon-Suk Hwang  Julie Dillon-Wallace  Marilyn Campbell  Jill Ashburner  Beth Saggers  Suzanne Carrington 《International Journal of Inclusive Education》2018,22(4):391-408

Students with ASC are at heightened risk for bullying and their understanding of bullying is known to protect them from involvement in it (Humphrey and Hebron 2015). However, only a handful of studies have examined how students with ASC understand traditional bullying and none of them focused on cyberbullying. To fill this gap, we investigated how traditional bullying and cyberbullying are understood from the perspectives of 89 students with ASC attending inclusive schools and 490 students without ASC. Twenty vignettes were used from (Campbell et al. 2017a), based on the Olweus (1999) definition of bullying and verified by a Delphi technique. In the majority of traditional bullying and cyberbullying vignettes, students with ASC made more accurate responses than inaccurate ones and demonstrated higher accuracy rates than students without ASC. Findings of linear multiple regression analyses pointed out ASC status as a predictive variable for understanding both types of bullying, along with students' age for understanding cyberbullying. The findings highlight the ability rather than inability to understand bullying in students with ASC. It is therefore critical to include the voices and experiences of students with ASC in our research endeavour.  相似文献

Knowledge of derivational suffixes in students with language learning disabilities     

Jennifer Windsor Ph.D.  Mina Hwang 《Annals of dyslexia》1997,47(1):57-68

Knowledge of derivational suffix meanings was investigated in 10- to 12-year-old students with language learning disabilities and individually matched chronological- and language-age peers. Students produced derived forms from nonce bases in an elicitation task and selected derived forms in a forced choice task. For instance, students produced a word to label the baby of an invented animal called a TEM (TEMlet, TEMette, TEMkin, etc.) and chose an appropriate label from four options (TEMlet, TEMkin, TEMship, TEMhood). Twenty-eight suffixes (e.g., less, y, ize) conveying seven derivational meanings (e.g., “without X,” “approximately X,” “to make X”) were studied. All groups showed higher accuracy on the forced choice task than on the elicitation task. However, elicitation task accuracy of students with language learning disabilities fell substantially below that of typically achieving students. Suffixes for “agent X,” “character of X,” and “to make X” were produced in the elicitation task with higher accuracy than suffixes for “approximately X,” “diminutive X,” and “state of X.” In both tasks, suffix use was associated with productivity (i.e., regularity of suffix attachment). All groups chose highly productive suffixes (e.g., TEMlet) over less productive suffixes (e.g., TEMkin) to convey each meaning.  相似文献
