Our study examines the environmental knowledge (EK) and behavioural outcomes of students studying ecotourism in Sydney, Australia. Three competing models were tested to examine the relationships between EK, participation intention (PI) in ecotourism programs, landscape likeability (LL) and social interactions (SI); and the study also tested the moderated mediation influence of gender differences and relationship length on mediators. Partial least squares-based structural equation modelling (PLS-SEM) was used to analyse the data collected from 173 residential tourism students. Key findings suggest whilst LL and PI are significant outcomes of EK, LL has a stronger mediating effect on PI compared to SI; and all mediation effects are further moderated by gender differences. However, only Model 3 confirms the moderating effect of the length of relationship. Noting the key role that EK plays in influencing their PI and LL, our study also suggests ways of developing the tourism students’ EK, through various experiential and pedagogical interventions. 相似文献

Participants were 45 mostly African-American or Latino young children (25 boys, 20 girls, mean age = 56.4 months), with about half recruited from a mental health facility and half from preschool settings. Children were administered two separate interviews examining their affectively-charged moral narratives regarding acts of victimization (Moral MSSB) and their attachment-related narratives (SAT). In addition, children's teachers or therapists completed assessments of the attachment-like aspects of their relationships with children (STRS), and a measure of children's behavior problems and competencies (C-TRF). Overall, after controlling for child age, gender, SES, and expressive language ability, children with more externalizing problems were more likely to describe aggressive themes, and less likely to mention adult aid or taking responsibility for transgressions in their moral narratives. In addition, more positive attachments (both the SAT and STRS) were associated with fewer externalizing problems. More than half of the total variance in children's externalizing scores could be predicted from a combination of the attachment and Moral MSSB variables. These findings have implications for understanding the affective origins of young children's externalizing behavior problems involving both peers and adults. 相似文献

Objective
Scandix pecten-veneris L. is a less studied wild edible herb and is considered an extinct plant species in many parts of the world. This study was designed to evaluate its phytochemical composition and biological potential of S. pecten-veneris L.Methods
Phytochemicals including alkaloids, flavonoids, polyphenols, and tannins were determined in extracts of S. pecten-veneris. Antioxidant activity was determined using 2,2-diphenyl-1-picrylhydrazyl (DPPH), while reducing power was tested by ferric reducing/antioxidant power (FRAP) assay. Antimicrobial activity against seven bacterial and four fungal strains was evaluated using agar well diffusion assay. Enzymes inhibition study was performed for urease, phosphodiesterase-I, and catalase-II.Results
S. pecten-veneris showed moderate antiradical activity and reducing potential of hydroxyl radicals to about 20% of the initial value. The antioxidant activity of various extracts of S. pecten-veneris showed a linear correlation with total phenolic contents in the order of water>n-butanol>chloroform>ethyl acetate>methanol extracts. S. pecten-veneris leaves showed the highest inhibitory activity against Staphylococcus aureus while the highest antifungal activity was observed against Candida albicans. The plant extract was most potent against urease enzymes but showed moderate activity against phosphodiestrase-I and carbonic anhydrase-II.Conclusions
Our data demonstrate that in addition to its culinary uses, S. pecten-veneris has good medicinal potential and hence could be used for treating some specific health ailments.44.

This study evaluated effect of mental rotation (MR) training on learning outcomes and explored effectiveness of teaching via three-dimensional (3D) software among medical students with diverse spatial intelligence. Data from n = 67 student volunteers were included. A preliminary test was conducted to obtain baseline level of MR competency and was utilized to assign participants to two experimental conditions, i.e., trained group (n = 25) and untrained group (n = 42). Data on the effectiveness of training were collected to measure participants’ speed and accuracy in performing various MR activities. Six weeks later, a large class format (LCF) session was conducted for all students using 3D software. The usefulness of technology-assisted learning at the LCF was evaluated via a pre- and post-test. Students’ feedback regarding MR training and use of 3D software was acquired through questionnaires. MR scores of the trainees improved from 25.9±4.6 points to 28.1±4.4 (P = 0.011) while time taken to complete the tasks reduced from 20.9±3.9 to 12.2±4.4 minutes. Males scored higher than females in all components (P = 0.016). Further, higher pre- and post-test scores were observed in trained (9.0±1.9 and 12.3±1.6) versus untrained group (7.8±1.8; 10.8±1.8). Although mixed-design analysis of variance suggested significant difference in their test scores (P < 0.001), both groups reported similar trend in improvement by means of 3D software (P = 0.54). Ninety-seven percent of students reported technology-assisted learning as an effective means of instruction and found use of 3D software superior to plastic models. Software based on 3D technologies could be adopted as an effective teaching pedagogy to support learning across students with diverse levels of mental rotation abilities. 相似文献

High-quality professional development is needed to prepare teachers to help students learn how to conduct online academic research and meet Common Core State Standards for English Language Arts. This study created and evaluated a Web-based professional development program with five instructional modules designed to prepare middle-school teachers to teach their students nine strategies for conducting academic research online. The online professional development program was specifically created to help teachers implement the previously developed online SOAR Student Toolkit curriculum with all students in inclusive classrooms. Results of a 2015–2016 pilot study conducted with 13 teachers and 477 students in sixth to eighth grades indicated that most teachers perceived the professional development program to be of high quality and relevant in helping them teach online research skills to their students. Students significantly improved online research skills after learning from trained teachers (27 percentage points improvement, from 18% at pretest to 45% at posttest). 相似文献

This article introduces playful learning as part of the decolonising project at institutes of higher learning in South Africa with specific reference to the discipline of communication design. Not only does the article interrogate the content of design education, specifically design for development, but more specifically the way that design for social innovation is taught. The article begins with a contextualisation of the decolonisation debate both locally and internationally, which is followed by a brief historical overview of formal design education. Design education’s trajectory informs the contemporary conception of design as a form of rhetoric. Design and play are then interfaced theoretically, and pragmatically through a case study to explore how deeper learning was made possible by play in a curriculum‐based project. Ultimately, the article aims to highlight the value of playful learning in design higher education to nurture alternate modes of design thinking that favour localised practice, intersubjective relationships between designers and their stakeholders and the enabling of students’ self‐realisation through real world experience. 相似文献
