Relations between EFL teachers’ formal knowledge of grammar and their in-action mental models of children's minds and learning     

Orly Haim  Sidney Strauss  Dorit Ravid 《Teaching and Teacher Education》2004,20(8):861

We studied the relations between English as a foreign language teachers’ grammar knowledge and their in-action mental models (MMs) of children's minds and learning. The grammar knowledge we examined was English wh-constructions. A total of 74 teachers completed an assessment task and were classified to have deep, intermediate or shallow knowledge. Ten teachers (five with deep and five with shallow level) were videotaped teaching wh-questions. The data were analysed qualitatively to determine the teachers’ MM, and then quantitatively to test similarities/differences in their MM's expression. The findings revealed an identical MM among all teachers that is expressed differently as a function of knowledge level.  相似文献

ABSTRACT

Purpose: This article explores how voluntary certifications influence the way cooperatives provide advisory services to their members and the influence of these services on agricultural practices. Design/Methodology/Approach: Case studies were conducted in four representative Costa Rican cooperatives interviewing twenty interviewed cooperative administrators and members to determine changes in advisory services and farming practices over the past twenty years and factors which influenced those changes. Findings: Certifications induce cooperatives to offer new services to support farmers. Cooperatives form collaborations with new stakeholders or reconfigure existing collaborations to provide advisory services to their members. These services have helped to shape farmers’ attitudes about sustainable farming practices, though farm-level changes may be small. The main change at the cooperative level is adding new topics for group training, and certification issues are directly linked with practices such as maintaining a farm record book or wearing a mask when applying pesticides. Practices which compete with productivity are unlikely to change. Practical Implications: The results are useful to improve the advisory services provided by cooperatives by better identifying the key issues to be addressed to fulfill the certifications’ requirements. Theoretical implications: Cooperatives are a relevant player to induce more sustainable practices, by providing or coordinating advisory services, but their efforts cannot be seen disconnected from a broader institutional environment. Originality/Value: We demonstrate that certifications change the intensity and scope of advisory services and induce cooperatives to engage with a more diverse network of stakeholders.  相似文献   

Archives in the trenches: repatriation of African National Congress liberation archives in diaspora to South Africa     

Mpho Ngoepe  Sidney Netshakhuma 《Archival Science》2018,18(1):51-71

The African National Congress (ANC) liberation archives were created in countries all over the world. These liberation archives form part of the national archival heritage of South Africa as they bridge the gap of undocumented history of people who were previously marginalised by the apartheid government. After the ban on liberation movements was lifted in South Africa, the ANC embarked on the process of identification and repatriation of the records that were fragmented throughout the world. This study investigated the approaches followed by the ANC in identifying and repatriating its liberation archives from the trenches to make them accessible. Qualitative data were collected through interviews with purposively selected employees of the African National Congress, MultiChoice, Africa Media Online and the Nelson Mandela Foundation who were involved in the repatriation of the liberation archives. Interview data were augmented through content analysis of ANC documents such as policies, websites and annual reports, as well as observation of the storage conditions of the liberation archives. The key findings revealed that the ANC established an archives management committee that played an important role in the identification, repatriation and, ultimately, digitisation of liberation archives. The committee utilised former liberation struggle members to identify records in ANC hosts in various countries. It was established that, although the ANC was aware of where its records were abroad, not all its records were repatriated to South Africa after the unbanning of the liberation movements. For example, there were host nations, like Italy, that disputed the return of the ANC liberation archives to South Africa. The liberation archives are in the custody of the Fort Hare University as a chosen official repository for the ANC. It is concluded that the repatriation of the liberation archives is an ongoing process, as not all records have been repatriated to South Africa. As the ANC is in power at the time of writing, this is the opportunity for the organisation to negotiate with countries that still have custody of its liberation archives, such as Italy, to repatriate such records to South Africa. A further study on legal ownership and copyright, digitisation and ensuring the authenticity of the ANC liberation archives is recommended. This study can be extended to other liberation movements in southern Africa.  相似文献   

Feeling Bad About Feel-Good Ads: The Emotional and Body-Image Ramifications of Body-Positive Media     

Ashley Kraus  Jessica Gall Myrick 《Communication Research Reports》2018,35(2):101-111

In recent years beauty companies have produced advertising campaigns purporting to make women feel better about their bodies and reverse the damage of thin-ideal media (e.g., The Dove Campaign for Real Beauty). Despite being celebrated in the popular press for the effort, little is known about how effective these advertisements are at healing issues of poor body image. In addition, little work has been done to explore the relationship between discrete emotions and body image. The present study was an experiment aimed at capturing the different discrete emotions experienced in a body-positive advertisement compared to traditional beauty ad. Findings assert that participants reported experiencing positive (e.g., elevation and hope) and negative (e.g., guilt and pride) discrete emotions significantly more than their counterparts in the traditional beauty ad condition. Results also show no significant difference in postexposure thin-ideal internalization between the two conditions.  相似文献   

Recreation for the Rich and Poor: A Contrast     

Richard G. Kraus 《Quest (Human Kinetics)》2013,65(1):48-58

Although professionals frequently neglect problem-setting because of their preoccupation with problem-solving, there are serious consequences of doing so. The products of problem-setting (missions, goals, objectives) are central to the process of professionalization and determine the extent to which a profession's activity is dynamic, not static. Problem-setting proceeds by the complementary processes of framing and naming. It involves the competing values of individuals and groups and results in a form of social editing. Professionals should become more reflective and reflexive in their approaches to problem-setting, while rejecting the assumption that today's problems are necessarily tomorrow's.  相似文献   

Confusion and complex learning during interactions with computer learning environments     

Blair Lehman  Sidney D'Mello  Art Graesser 《The Internet and Higher Education》2012,15(3):184-194

Folk wisdom holds that being confused is detrimental to learning. However, research on emotions and learning suggest a somewhat more complex relationship between confusion and learning outcomes. In fact, it has been proposed that impasses that trigger states of cognitive disequilibrium and confusion can create opportunities for deep learning of conceptually difficult content. This paper discusses four computer learning environments that either naturally or artificially induce confusion in learners in order to create learning opportunities. First, an Intelligent Tutoring System called AutoTutor that engenders confusion through challenging problems and vague hints is described. The remaining three environments were specifically designed to induce confusion through a number of different interventions. These interventions include device breakdowns, contradictory information, and false feedback. The success and limitations of confusion induction and the impact of confusion resolution on learning are discussed. Potential methods to help learners productively manage their confusion instead of being hopelessly confused are also discussed.  相似文献   

Dynamics of affective states during complex learning     

Sidney D’Mello  Art Graesser 《Learning and Instruction》2012,22(2):145-157

We propose a model to explain the dynamics of affective states that emerge during deep learning activities. The model predicts that learners in a state of engagement/flow will experience cognitive disequilibrium and confusion when they face contradictions, incongruities, anomalies, obstacles to goals, and other impasses. Learners revert into the engaged/flow state if equilibrium is restored through thought, reflection, and problem solving. However, failure to restore equilibrium as well as obstacles that block goals trigger frustration, which, if unresolved, will eventually lead to boredom. The major hypotheses of the model were supported in two studies in which participants completed a 32-35 min tutoring session with a computer tutor. Their affective states were tracked at approximately 110 points in their tutoring sessions via a retrospective affect judgment protocol. Time series analyses confirmed the presence of confusion-engagement/flow, boredom-frustration, and confusion-frustration oscillations. We discuss enhancements of the model to address individual differences and pedagogical and motivational strategies that are inspired by the model.  相似文献   

The basis of liability for broadcasting defamatory remarks     

Sidney A. Diamond 《广播与电子媒介杂志》2013,57(1):40-43

In an article that appeared in Winter 1958–1959 issue of the Journal of Broadcasting, Profesor Gordon Greb added a new contender for the title of “oldest station in the nation.”; As a result, KQW has joined KDKA, WHA and WWJ as a candidate for the honor of primacy in American radio broadcasting. Although Greb's article created as much interest and controversy as any that has appeared in the Journal, it did not—and could not—still the confidence of the other claimants.

In the instant article, Mr. R. Franklin Smith does the field of historical radio research a service by setting forth, for the first time, a logical set of criteria by which to judge these conflicting claims. To illustrate he has utilized early records of WHA. Using these criteria, it is shown that WHA cannot claim to have been a true broadcasting station before the latter part of 1920. Comparison of the claims of the several contenders is outside the scope of this article. However, it would be extremely interesting if these criteria were applied to the conflicting claims by persons having access to the detailed station records and other data necessary for thorough analysis.

Perhaps Mr. Smith has given us the impetus and the tools necessary for determining which station really was the “oldest in the nation.”  相似文献
