Indigenous knowledge erodes rapidly. When the loss of this knowledge negatively affects the lives and health of traditionally living rural communities, a drive to conserve indigenous knowledge becomes vital. This article argues that the transfer of indigenous knowledge on traditional vegetables will ensure the availability and utilisation of this important food source for resource-poor rural communities. Data collected on the present use of traditional vegetables at a rural Xhosa village in the Eastern Cape Province of South Africa documented indigenous practices of traditional vegetable use and measured attitudes and perceptions of young women. Findings revealed that although traditional vegetables are readily available, there is a decline in the use of traditional vegetables in this village. Since the loss of associated indigenous knowledge is a reality, and in view of the negative attitude towards traditional vegetables, future use of this valuable food source is threatened. The transfer of the associated indigenous knowledge holds the key to the potential future use of traditional vegetables. Altered perceptions of traditional vegetables are crucial for the conservation of the associated indigenous knowledge. As a result awareness campaigns to promote the use of traditional vegetables, related nutritional education, including proper cooking and preservation techniques are necessary. 相似文献

Cognitive load theory (CLT) has been successful in identifying instructional formats that are more effective and efficient
than conventional problem solving in the initial, novice phase of skill acquisition. However, recent findings regarding the
“expertise reversal effect” have begun to stimulate cognitive load theorists to broaden their horizon to the question of how
instructional design should be altered as a learner's knowledge increases. To answer this question, it is important to understand
how expertise is acquired and what fosters its development. Expert performance research, and, in particular, the theoretical
framework of deliberate practice have given us a better understanding of the principles and activities that are essential
in order to excel in a domain. This article explores how these activities and principles can be used to design instructional
formats based on CLT for higher levels of skills mastery. The value of these formats for e-learning environments in which
learning tasks can be adaptively selected on the basis of online assessments of the learner's level of expertise is discussed.

Research demonstrates that children can make more significant gains through explicit instruction of vocabulary than implicit instruction (Blachowicz and Fisher in Teaching vocabulary in all classrooms, Allyn & Bacon, Boston, MA, 2010; Dalton and Grisham in Read Teach 64(5):306–317, 2011). Effective explicit instruction often includes high quality conversations with teachers and peers (Towson et al. in J Early Interv 38(4):230–246, 2016; Wasik in Read Teach 63(8):621–633, 2010). Data for this study were collected from a larger study designed to explore students’ use of vocabulary words following explicit instruction with the words during an interactive read-aloud. A deeper microanalysis of student discussion, scaffolded by adults, was conducted. The transcribed student discussions, recorded during peer talk, were analyzed using NVivo 10 (QSR International in NVivo (version 10). NVivo qualitative data analysis software, QSR International, Doncaster, VIC, 2012) software. These case studies describe the vocabulary development of two children with diagnosed speech and language disorders and one child without a speech and language impairment. 相似文献

The present study investigated preservice teachers’ self‐efficacy in classroom management involving students with symptoms of Attention Deficit/Hyperactivity Disorder (ADHD). A total of 137 Chinese preservice teachers were randomly presented with one of four vignettes involving a student character with ADHD symptoms, with manipulations including the character’s gender and diagnostic label of ADHD. Upon reading the vignette, participants responded to questions concerning their self‐efficacy in inclusive classroom management involving the character. Findings based on analysis of covariance indicated an interaction effect of the vignette character’s gender and label on teachers’ self‐efficacy. Specifically, teachers perceived greater self‐efficacy in a classroom involving a girl with an ADHD label than in a classroom involving a girl with no label or a boy with a label. Findings enriched the literature concerning the roles of gender and label in preservice teachers’ self‐efficacy toward inclusive classroom management. 相似文献

Three emotion work themes were displayed in the discourse of individuals who lost their jobs and of their family members. Foregrounding-backgrounding of emotions indicated not only how some individuals and family members exerted effort to express positive emotions, but also why they would do so (for deep authenticity). In the construction of normalcy, respondents made an effort to portray and enact their lives as similar to the way things were before the job loss. By (re)instituting traditional masculinities, the men who lost their jobs were able to be "real" men in an emasculating situation. Taken together, these findings offer possibilities for further theoretical development and for communication interventions that can be applied by human resource professionals, career and outplacement counselors, family members, friends, and the individuals themselves. 相似文献

Strategic alignment involves the development and reconfiguration of information technology (IT) to support business strategies. This paper applies the dynamic capabilities perspective to analyze the strategic information system alignment process. The paper further argues the approach is constructive in understanding and overcoming difficulties in achieving and sustaining alignment. From a longitudinal case study of a semiconductor company in Taiwan, the results show an unaligned strategic information system (with an implemented IT strategy that varies from the intended IT strategy) impedes the development of IT. Path dependence, or the implications of prior IT decisions, is another barrier for alignment. A broader view of intended alignment, focusing on IT combined with clear business vision, can be beneficial for adding future IT resources. In addition, dynamic capabilities, which are critical for the creation and strength of IT resources, positively influence the alignment process and its future implementation success. 相似文献
