The development of CALL has been accompanied by a debate about which theoretical foundations it should be built upon. This paper will ask what the relationship between CALL and models of language and learning has been, and consider what it should be. Research undertaken using ICT in order to identify issues relevant to second language acquisition (SLA)will be examined, and its implications noted. The application of interactionalist models of SLA will be considered and the contribution that task-based language learning could make to CALL investigated. The concept of "student-directed" CALL is used in order to distinguish the SLA-based interactionalist models proposed from the many CALL approaches based on gap fills, drilling, etc. and from the many tutor-led programmes in areas such as EAP.  相似文献

There is no question that Computer Assisted Language Learning(CALL) has been a feature of teaching and learning in college.CALL plays a significant role in second language teaching.This article will focus on an overview of three different types of roles of CALL to demonstrate its application in Chinese college English teaching.  相似文献

1870- 1947 Louise Cummings was born in Hamilton, Ontario. Her early education was obtained in the public schools and Collegiate Institute at Hamilton. She received her B.A. (1895) with First Class Honors in Mathematics from the University of Toronto. The year 1895-96 was spent in graduate study under the direction of Professor DeLury of Toronto University. In 1896-97 Cummings held a fellowship in mathematics at the University of Pennsylvania, and the following year she was a student i…  相似文献

Tea polyphenols have been shown to have anticancer activity in many studies.In the present study,we investigated effects of theaflavin-3-3'-digallate(TF3),one of the major theaflavin monomers in black tea,in combination with ascorbic acid(AA),a reducing agent,and(-)-epigallocatechin-3-gallate(EGCG),the main polyphenol presented in green tea,in combination with AA on cellular viability and cell cycles of the human lung adenocarcinoma SPC-A-1 cells.The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide(MTT) assay showed that the 50% inhibition concentrations(IC50) of TF3,EGCG,and AA on SPC-A-1 cells were 4.78,4.90,and 30.62 μmol/L,respectively.The inhibitory rates of TF3 combined with AA(TF3+AA) and EGCG combined with AA(EGCG+AA) at a molar ratio of 1:6 on SPC-A-1 cells were 54.4% and 45.5%,respectively.Flow cytometry analysis showed that TF3+AA and EGCG+AA obviously increased the cell population in the G0/G1 phase of the SPC-A-1 cell cycle from 53.9% to 62.8% and 60.0%,respectively.TF3-treated cells exhibited 65.3% of the G0/G1 phase at the concentration of its IC50.Therefore,TF3+AA and EGCG+AA had synergistic inhibition effects on the proliferation of SPC-A-1 cells,and significantly held SPC-A-1 cells in G0/G1 phase.The results suggest that the combination of TF3 with AA or EGCG with AA enhances their anticancer activity.  相似文献

The field of Computer Assisted Language Learning (CALL) has transformed dramatically--from the days of the behaviourist approach that dominated CALL in the 1970s to the dynamism of Interactive approach in the 1990s under the immense influence of information communication technology (ICT). Regardless of these periodic changes and improvements, successful implementation of CALL programs in schools decisively hinges on critical assessment and decisions that are undertaken by schools. As such, the responsibility of the technology adopters in this respect must reflect school's aspirations and understandably, students' abilities, interests and needs This paper attempts to clarify these issues through a case study of implementation of CALL in an urban secondary school in Malaysia. The outcome of the case study establishes critical considerations that need to be arbitrated to successfully implement CALL programs for English language teaching (ELT) at the school level.  相似文献

To investigate inter- and intra-hemispheric electroencephalography (EEG) coherence at rest and during photic stimulation of patients with Alzheimer‘s disease (AD). Thirty-five patients (12 males, 23 females; 52-64 y) and 33 sex- and age-matched controls (12 males, 21 females; 56-65 y) were recruited in the present study. EEG signals from C3-C4, P3-P4, TS-T6 and O1-O2 electrode pairs resulted from the inter-hemispheric action, and EEG signals from C3-P3, C4-P4, P3-O1, P4-O2, C3-O1, C4-O2, TS-O1 and T6-O2 electrode pairs resulted from the intra-hemispheric action. The influence of inter- and intra-hemispheric coherence on EEG activity with eyes closed was examined, using fast Fourier transformation from the 16 sampled channels. The frequencies of photic stimulation were fixed at 5, l0 and 15 Hz, respectively. The general decrease of AD patients in inter- and intra-hemispheric EEG coherence was more significant than that of the normal controls at the resting EEG, with most striking decrease observed in the alpha-1 (8.0-9.0 Hz) and alpha-2 (9.5-12.5 Hz) bands. During photic stimulation, inter- and intra-hemispheric EEG coherences of the AD patients having lower values in the alpha (9.5-10.5 Hz) band than those of the control group. It suggests that under stimulated and non-stimulated conditions, AD patients had impaired inter- and intra-hemispheric functional connections, indicating failure of brain activation in alpha-related frequency.  相似文献

Only about one out of every four American women gets the recommended daily calcium intake-1, 000 to 1,300 mg, the equivalent of about three and a half of skim milk(脱脂乳)- often because they' re slumping dairy products in an attempt to lose weight. "They are shooting themselves in the foot, " says Michael B. zemel, Ph. D, director of the University of Tennessee' s Nutrition Institute, in Knoxville(诺克斯维尔). In this research, he's found that a high-calcium diet actually helps overweight people to drop pounds, Zemel says that  相似文献
