Motivating Students, Improving Schools

Asks questions, regarding the implications of motivation theory for school reform. This volume portrays the potential of research methods and re-examines tried and true conceptions of the nature and nurture of motivation. It also suggests issues and points to venues for application.

Student Motivation, Cognition, and Learning

Designed to present some of the current research on student motivation, cognition, and learning, this book serves as a festschrift for Wilbert J. McKeachie who has been a leading figure in college teaching and learning. The contributions to this volume were written by former students, colleagues and friends. A common focus on a general or social cognitive view of learning is shared throughout the volume, but there are significant differences in the perspectives the researchers bring to bear on the issues. They provide an excellent cross-section of current thinking and research on general cognitive topics such as students' knowledge structures, cognitive and self-regulated learning strategies, as well as reasoning, problem solving, and critical thinking. Social cognitive and motivational topics are also well represented, including self-worth theory and expectancy-value models. More importantly, an explicit attempt is made to link cognitive and motivational constructs theoretically and empirically. This area of research is one of the most important and promising areas of future research in educational psychology. Finally, most of the chapters address instructional implications, but several explicitly discuss instructional issues related to the improvement of college students' motivation and cognition.

Teaching the Arts to Engage English Language Learners

Written for prospective and practicing visual arts, music, drama, and dance educators, Teaching the Arts to Engage English Language Learners offers guidance for engaging ELLs, alongside all learners, through artistic thinking. By paying equal attention to visual art, music, drama, and dance education, this book articulates how arts classrooms can create rich and supportive contexts for ELLs to grow socially, academically, and personally. The making and relating, perceiving and responding, and connecting and understanding processes of artistic thinking, create the terrain for rich curricular experiences. These processes also create the much-needed spaces for ELLs to gain communicative practice, skill, and confidence. Special features include generative texts such as films, poems, and performances that function as springboards for arts educators to adapt according to the needs of their classroom; teaching tips, formative assessment practices, and related instructional tables and resources; an annotated list of internet sites, reader-friendly research articles, and instructional materials; and a glossary for readers’ reference.

Anti-cancer Activity of Triterpenoids Isolated from Luvunga Scandens Against MCF-7 Cells

Luvunga scandens belong to the family of Rutaceae which usually inhabits tropical and moist environment. This plant is known as 'Mengkurat Jakun' among locals and used traditionally to treat fever and fatigue via decoction. The study aimed to elucidate the compounds from L. scandens stem, which were isolated using bioactivity guided isolation together with their mechanism of action on human breast cancer cell (MCF-7). The bioactivity-guided isolation of cytotoxic agent of the stem of L. scandens resulted in the isolation and characterization of a new triterpenoid from this species, 3-oxotirucalla-7,24-dien-21-oic-acid (2), along with a known triterpenoid, flindissol (1). The isolation was conducted using chromatographic techniques on silica gel and sephadex LH-20. The structures of the isolated compounds were elucidated on the basis of spectroscopic analysis including UV, IR, NMR, MS and 2D NMR. The cytotoxic activity of the plant on the proliferation of MCF-7 cell line was evaluated by MTT, WST-1 assay, scanning electron microscope (SEM), flow cytometry and RT-qPCR. The cytotoxic evaluation of the extracts showed that IC50 value of the dichloromethane (LSC-SD) and methanol (LSC-SM) extracts from the stem were 75.0 and 77.0 μg/mL respectively. Whereas IC50 value of n-hexane (LSF-H), n-hexane:DCM (LSF-HD), DCM (LSF-D) and DCM:MeOH (LSF-DM) fraction extracts were 97.5, 35, 98.9 and 94 μg/mL respectively. The IC50 value of MeOH (LSF-M) fraction could not be extrapolated since none of the concentration of this extract was able to reduce the proliferation activity to 50 %. Compound 1 and 2 showed potent cytotoxicity against MCF-7 cell line with IC50 values of 13.8 μM and 27.5 respectively after 24 h of treatment. Doxorubicin was used as a positive control drug with IC50 values of 6.21 μM. Morphological analysis of the cells surface exhibit the apoptosis results after 24 h treated with LSC-SD extract, 1 and 2, where the cells were rounded up, shrank and lost contact with neighboring cells. Apoptosis of MCF-7 cells treated with both compounds were confirmed by flow cytometry. The results show that compound 1 and 2 exert their anti-proliferative effect on MCF-7 cells through inhibiting cell cycle where the distribution of cells at Sub G1 phase was 7.7 and 9.3 % respectively. Further evident of apoptosis induction by compound 1 and 2 towards MCF-7 cell lines were assayed by RT-qPCR on the expression of PUMA, caspase-8 and caspase-9. In this assay, both compounds showed the increased of the expression of PUMA, caspase-8 and caspase-9 gene. In conclusion, both triterpenoids, 3-oxotirucalla-7,24-dien-21-oic-acid (2) and flindissol (1) have a potential to be developed as anticancer agents against breast cancer.
