In this study, we investigated fifth graders’ (n = 52) fall literacy, academic language, and motivation and how these skills predicted fall and spring comprehension monitoring on an eye movement task. Comprehension monitoring was defined as the identification and repair of misunderstandings when reading text. In the eye movement task, children read two sentences; the second included either a plausible or implausible word in the context of the first sentence. Stronger readers had shorter reading times overall suggesting faster processing of text. Generally fifth graders reacted to the implausible word (i.e., longer gaze duration on the implausible vs. the plausible word, which reflects lexical access). Students with stronger academic language, compared to those with weaker academic language, generally spent more time rereading the implausible target compared to the plausible target. This difference increased from fall to spring. Results support the centrality of academic language for meaning integration, setting standards of coherence, and utilizing comprehension repair strategies.  相似文献   

Understanding how student-constructed stop-motion animations promote mechanistic reasoning: A theoretical framework and empirical evidence

Previous studies have documented the promising results from student-constructed representations, including stop-motion animation (SMA), in supporting mechanistic reasoning (MR), which is considered an essential thinking skill in science education. Our current study presents theoretically and empirically how student-constructed SMA contributes to promoting MR. As a theoretical perspective, we propose a framework hypothesizing the link between elements of MR and the construction nature of SMA, that is, chunking and sequencing. We then examined the extent to which this framework was consistent with a multiple-case study in the domain of static electricity involving five secondary school students constructing and using their own SMA creation for reasoning. In addition, students' reasoning in pre- and postconstruction of an SMA was examined. Our empirical findings confirmed our framework by showing that all students identified the basic elements of MR, that is, entities and activities of entities, when engaging in chunking and sequencing. Chunking played a role in facilitating students to identify entities responsible for electrostatic phenomena, and sequencing seemed to elicit students to specify activities of these entities. The analysis of students' reasoning in pre- and postconstruction of SMA found that student-generated SMA has a potential effect on students' retention of the use of MR. Implications for instruction with SMA construction to support MR are discussed.  相似文献

The importance of reflection in experiential learning with community and youth workers for the learning age     

Mary Kenny  Sue Ralph  Marie Brown 《International Journal of Lifelong Education》2013,32(2):115-125

The New Labour government, in its Green Paper on the Learning Age, published in February 1998, put lifelong learning at the heart of its programme. In this article we aim to demonstrate that there is a direct parallel between the processes outlined in the Green Paper and the processes of experiential learning and community development by focusing on the Diploma in Community and Youth Work Studies run by the Community Work Unit (CWU) based in the Centre for the Development of Continuing Education at the University of Manchester.

Community action provides a setting for informal education. Community workers are in a unique position in relation to developing the potential for learning in the groups and individuals with whom they work. Their education and training should enable them to articulate and value their experience and reflect upon it in order to establish a meaningful basis for further self- and/or community development. We will explore how the CWU uses participative learning methods which recognize, value and use the experience and understanding of the participants as a basis for their own and others’ learning, and the relevance of these learning methods to the work practice of the participants.  相似文献

Biodeterioration of Incralac used for the protection of bronze monuments   总被引：2，自引：0，他引：2

Outdoor bronze sculptures are highly susceptible to corrosion in many environments and organic coatings are widely used for their protection. The purpose of this study was to determine the susceptibility of the commonly used coating Incralac to biodeterioration by microorganisms. A yeast was isolated from a bronze statue treated with Incralac and its ability to degrade Incralac was determined using growth curves, scanning electron microscopy (SEM), and electrochemical impedance spectroscopy (EIS). The organism grew slowly on Incralac in liquid culture, but SEM images demonstrated its ability to adhere to Incralac coated metal. Additionally, the yeast caused a rapid drop in the low frequency impedance of Incralac coated metal that was not observed under sterile conditions, indicating that the organism accelerated deterioration of the coating. The potential for microbial growth to accelerate deterioration of Incralac should be considered when developing a maintenance strategy for the protection of outdoor metal monuments.  相似文献

Developing Peer Mentoring through Evaluation     

Ralph Hall  Zarni Jaugietis 《Innovative Higher Education》2011,36(1):41-52

Peer mentoring programs are an important component in the strategy to enhance the first year undergraduate experience. The operation of these programs needs to be informed by evidence as to their effectiveness. In this article we report on a six-year study of the development of a peer mentoring program in which feedback is used to improve program implementation. Evidence from surveys of participants in the program shows that this process has significantly enhanced their experiences and that the effects of these benefits have increased throughout the life of the program. Moreover, participation in the program enhanced the leadership, communication, and organizational skills of the peer mentors.  相似文献   

Biomechanics and visual-motor control: how it has, is, and will be used to reveal the secrets of hitting a cricket ball   总被引：1，自引：0，他引：1  

Sarpeshkar V  Mann DL 《Sports biomechanics / International Society of Biomechanics in Sports》2011,10(4):306-323

Cricket batting is an incredibly complex task which requires the coordination of full-body movements to successfully hit a fast moving ball. Biomechanical studies on batting have helped to shed light on how this intricate skill may be performed, yet the many different techniques exhibited by batters make the systematic examination of batting difficult. This review seeks to critically evaluate the existing literature examining cricket batting, but doing so by exploring the strong but often neglected relationship between biomechanics and visual-motor control. In three separate sections, the paper seeks to address (i) the different theories of motor control which may help to explain how skilled batters can hit a ball, (ii) strategies used by batters to overcome the (at times excessive) temporal constraints, and (iii) an interpretation from a visual-motor perspective of the prevailing biomechanical data on batting.  相似文献
