Empowerment and relationships: A classroom model to enhance student motivation

This project focused on the goal of establishing a classroom model of motivation in which the source of student motivation is based on internal mechanisms or structures, along with the establishment of greater self-regulatory opportunities for students, and which results in greater student empowerment and motivation. One-hundred current elementary and secondary teachers and 100 university preservice teacher education students completed a 40-item Likert-type questionnaire that focused on four classroom dimensions of affirmation, rejection, student empowerment and teacher control. The results of this project suggested that, although veteran and preservice teachers agreed on the need for teacher control in the classroom, there was less agreement about their perceptions of the need to create a classroom environment of positive affirmation and student empowerment. Implications for future research and the need for creating an affirming, empowering, motivational classroom environment are discussed in light of the limitations for teachers and schools to encourage these constructs associated with recent federal legislative policies.

A technological pedagogical content knowledge based instructional design model: a third version implementation study in a technology integration course

This paper presents the third version of a technological pedagogical content knowledge (TPACK) based instructional design model that incorporates the distinctive, transformative, and integrative views of TPACK into a comprehensive actionable framework. Strategies of relating TPACK domains to real-life learning experiences, role-playing, and teachers as designers were developed based on the three views and integrated into the third version of the model. The model was then applied in a teacher education undergraduate course on technology integration. A case study approach was used. Data were collected from the participants’ discussion worksheets, lesson designs, and the researchers’ field observation notes. Data analysis results suggest that the strategies integrated into the model helped the participants deepen their understanding of student-centered technology applications and practice TPACK. Findings, implications, and future research possibilities are discussed.     

试论"状--动--宾"结构的层次分析

Antimelanogenic effects of <Emphasis Type="Italic">Inula britannica</Emphasis> flower petal extract fermented by <Emphasis Type="Italic">Lactobacillus plantarum</Emphasis> KCCM 11613P

The inhibitory effects of Lactobacillus plantarum-fermented and non-fermented Inula britannica extracts on the tyrosinase activity were comparatively investigated to examine whether and how they improve the whitening activity, and the contents of total flavonoids and polyphenolics as bioactive compounds were determined. The skin whitening activity using in vitro or ex vivo tyrosinase and L-3,4-dihydroxyphenylalanine (L-DOPA) staining was examined. The total flavonoid content (TFC) was increased by 13.4% after 72 h-fermentation. The viabilities of the B16F10 cells treated with the fermented and non-fermented control extracts were 100.26% and 92.15% at 500 μg/ml, respectively. In addition, the inhibition of tyrosinase activity was increased by the fermented samples from 29.33% to 41.74% following fermentation for up to 72 h. The tyrosinase activity of the untreated control group was increased to 145.69% in B16F10 cells. The results showed that I. britannica fermented by L. plantarum dose-dependently inhibited tyrosinase activity, which was stimulated by α-melanocyte stimulating hormone. These results suggest that lactic fermented I. britannica extracts can be used as effective skin-whitening materials.
