Improving Student Learning through a Team-Based Learning Approach in a Retailing Math Course

( Keunyoung Oh ) 복식문화학회 2016 Fashion, industry and education Vol.14 No.1

Passive learning attitudes and lack of enthusiasm in a retailing math course is quite common and a significant number of students do express their frustrations and struggles by seeking extra help outside the classroom. In order to promote students` active participation in class and to improve their performance and overall satisfaction with the course, a modified team-based learning (TBL) method was implemented in a retailing math course in two consecutive semesters. Implementing TBL into a retailing math course would improve students` accountability for their own learning, increase student interactions and engagement, and develop teamwork and collaboration skills. The scores on the midterm and final tests indicated that students` performance improved especially for the students who scored below 80% on each test when TBL was implemented. Students` reflection on the TBL activities done in class throughout the semester indicated that these TBL activities help them solidify the concepts taught in class better. They were able to realize their own mistakes and other group members who got the question right helped them understand. To maximize the benefit of TBL, it is suggested to implement TBL within the flipped classroom. Further research is called for to evaluate the effect of TBL on long-term knowledge retention among college students.

Tuban, East Java, Indonesia has a long history. Since centuries ago, Tuban has Fashion professionals these days agree that changes in the fashion business are essential and highly value creativity as a genuine source for generating new ideas in fashion products as well as fashion business practices. As fashion professionals deal with problems of which solutions do not exist or that need innovative solutions for brand or product differentiation in the fast-paced environments, interest in creativity and creative problem solving in the field has increased; therefore, fashion educators have realized that there has been an increasing need for incorporating creativity or creative problem solving into the fashion curriculum. In this study, the researcher intended to review previous research on the use of creative problem solving in classrooms in various disciplines including the field of fashion education to provide insights and suggestions for fashion educators to integrate creative problem solving into the fashion education curriculum. Previous attempts to apply creative problem solving to solve issues in fashion classrooms have mostly limited to promoting divergent thinking techniques. It is suggested for fashion educators as well as fashion students to consider creative problem solving as a process consisting of the four distinct stages in which both divergent and convergent thinking techniques should be properly utilized stimulating various thinking strategies.

Fashion trend is more than a social phenomenon that multitudes of people accept as popular styles of clothing. The purpose of this study was to understand the influence of fashion trend over time and distance. Geographically thousands of miles apart, the U.S. has strongly influenced fashion in Korea, revealed by references and historic depictions collected from literature and web sites. Results of the study are summarized as five issues: First, emergence of female missionaries from the U.S. American missionaries working in the late Great Korean Empire performed a significant role importing Western culture to Korea. Second, as opportunities of education increased, women studying abroad introduced Western fashion to Koreans when they returned to Korea. They were more open to Western culture than other Koreans and moderately harmonized their Korean sentiment and Western culture, mitigating cultural shock and enabled other Koreans to accept Western culture. Third, the effect of fashionistas on media. Singers working for U.S. armies stationed in Korea and movie stars appearing in Hollywood movies profoundly affected Korean pop culture and fashion trends in Korea. Fourth, following First Lady Jacqueline Kennedy of the U.S. She was an influential figure in those days and a fashion leader as well. Lastly, acceptance of working girl fashion depicted in American television shows. American working girls depicted on American TV shows were highly admired by young Korean women, so the fashion of American working girls became a major fad among young Korean women.

A hierarchical model of self-determined motivation for thrift shopping behavior

Oh, Keunyoung,Choi, Yun-Jung The Costume Culture Association 2017 服飾文化硏究 Vol.25 No.3

A consumer is an individual entity with various motivations. This study is intended to incorporate a hierarchical structure of motivation to understand self-determined motivation for purchasing secondhand merchandise at thrift stores. A conceptual model adopted from Cadwallader et al. (2010)'s comprehensive model of motivation used in a marketing context was developed to investigate motivational process in secondhand merchandise shopping. The conceptual model includes the three levels of motivational structure-the global, contextual (environmental concern and frugality), and situational motivation. A series of the causal relationships among the three levels of self-determined motivations and buying intention to shop at thrift stores were hypothesized. A total of 219 respondents from two different northeastern state universities in the U.S. completed a self-administered survey. The results indicated that secondhand merchandise shopping is well explained in the hierarchical structure of self-determined motivation where the global motivation had a positive impact on the contextual motivations regarding environmental concern and frugality. Of the two contextual motivations, only environmental concern had a positive impact on situational motivation for shopping at thrift stores. Finally, the situational motivation positively influenced the intention to shop at thrift stores. The results of this model suggest that the hierarchical structure of self-determined motivation would be a very useful framework to understand consumer behavior for apparel shopping. Also, further research can be done to identify other contextual motivational factors to understand consumer motivation for shopping at thrift stores.

Facilitating creative problem solving process as a teaching tool in fashion marketing classrooms

Keunyoung Oh 복식문화학회 2019 服飾文化硏究 Vol.27 No.1

A teaching manual was developed to incorporate the creative problem solving process into a fashion marking course. Students’ creativity, problem solving, critical thinking, and analytical thinking are promoted by applying the creative problem solving process systematically to solve authentic business problems experienced by local apparel business owners. This teaching manual is based on the FourSight Model that consists of Clarify, Ideate, Develop, and Implement. Various tools promoting divergent thinking are also utilized in the process. A local fashion business is invited as a problem owner and four resource groups are formed with students based on the results of the Kirton Adaption Innovation Inventory. Each resource group consists of 6-8 students. The creative problem solving process is implemented into a classroom setting as four 75-minutes sessions that are held twice a week for two consecutive weeks. The local fashion business owner will be in presence during the first (Clarify) and last (Implement) sessions. The instructor facilitator meets with the problem owner outside the classroom three times including pre-session client interview, after the second (Ideate) session, and before the third (Develop) session. This modified CPS manual for fashion marketing and merchandising courses provides practical guidelines to work with local fashion businesses while providing students with learning opportunities of the creative problem solving process.

This study evaluated the synthesis of optimal materials for high efficiency adsorption and removal characteristics of Cs-137 for radioactive contaminated water, and considered thermal treatment methods to stabilize the spent adsorbent generated after treatment. We synthesized a composite adsorbent with a combination of impregnating metal ferrocyanide that improves the selectivity of Cs adsorption with zeolite capable of removing Cs as a support. The Cs removal efficiency of the composite adsorbent was evaluated, and the stability change of Cs according to the high-temperature sintering was evaluated as a stabilization method of the spent adsorbent. The metal ferrocyanide content of the adsorbent was in the range of 11.8~36.0%. The adsorption experiments were performed using a simulated liquid waste to have a total Cs concentration of 1 mg/L while containing a trace amount of Cs-137, and then gamma radioactivity was analyzed. In order to evaluate the stabilization of the spent adsorbent, heat treatment was performed in the range of 500~1,100°C, and the volatilization rate of Cs during heat treatment and the leaching rate of Cs after heat treatment were compared. In the adsorption experiment, the Cs removal efficiency was higher than 99%, regardless of the amount of metal ferrocyanide in the composite adsorbent. In the sintering experiment on the spent adsorbent, it was confirmed that there was no volatilization of Cs up to 850°C, and then the volatilization rate increased as the heating temperature increased. On the other hand, the leaching rate of Cs in the sintered adsorbent tends to significantly decrease as the heating temperature increases, so that Cs can be stabilized in the sintered body. In addition, as the content of metal ferrocyanide increases, the volatilization rate of Cs rapidly increases, indicating that the unstable metal ferrocyanide in the adsorbent may adversely affect the removal of Cs as well as the thermal treatment stability.
