The Error in Trial and Error: Exercises on Phrasal Verbs

An analysis of 44 commercially available EFL textbooks found that it is common for textbooks to present learners with exercises on phrasal verbs without first providing relevant input to help them. In these cases, the learners are likely to resort to trial-and-error and are then expected to learn from feedback. We report an experiment conducted with Japanese EFL students (N=140) in which we compare the effectiveness of such a trial-and-error method with a retrieval procedure in which students first study a set of phrasal verbs and then complete an exercise. Scores on both an immediate and a one-week delayed post-test suggest superiority of retrieval over the trial-and-error procedure, where, despite the provision of feedback, 25% of the wrong exercise responses were reproduced in the delayed post-test

Contrastive focus and emphasis

The paper puts forward a discourse-semantic account of the notoriously evasive phenomena of contrastivity and emphasis. Based on new evidence from Chadic, it is argued that occurrences of focus that are treated in terms of ‘contrastive focus’, ‘kontrast’ (Vallduví-Vilkuna 1998) or ‘identificational focus’ (É. Kiss 1998) in the literature should not be analyzed in familiar semantic terms as involving the introduction and subsequent exclusion of alternatives. Rather, an adequate analysis must take into account discourse-semantic notions like ‘hearer expectation’ or ‘discourse expectability’ of the focused content in a given discourse situation. The less expected the focus content is judged to be for the hearer, relative to the Common Ground, the more likely a speaker is to mark the focus constituent by means of special grammatical devices, thus giving rise to emphasis

Do online resources give satisfactory answers to questions about meaning and phraseology?

In this paper we explore some aspects of the differences between printed paper dictionaries and online dictionaries in the ways in which they explain meaning and phraseology. After noting the importance of the lexicon as an inventory of linguistic items and the neglect in both linguistics and lexicography of phraseological aspects of that inventory, we investigate the treatment in online resources of phraseology – in particular, the phrasal verbs wipe out and put down – and we go on to investigate a word, dope, that has undergone some dramatic meaning changes during the 20th century. In the course of discussion, we mention the new availability of corpus evidence and the technique of Corpus Pattern Analysis, which is important for linking phraseology and meaning and distinguishing normal phraseology from rare and unusual phraseology. The online resources that we discuss include Google, the Urban Dictionary (UD), and Wiktionary

The source ambiguity problem: Distinguishing the effects of grammar and processing on acceptability judgments

Judgments of linguistic unacceptability may theoretically arise from either grammatical deviance or significant processing difficulty. Acceptability data are thus naturally ambiguous in theories that explicitly distinguish formal and functional constraints. Here, we consider this source ambiguity problem in the context of Superiority effects: the dispreference for ordering a wh-phrase in front of a syntactically “superior” wh-phrase in multiple wh-questions, e.g., What did who buy? More specifically, we consider the acceptability contrast between such examples and so-called D-linked examples, e.g., Which toys did which parents buy? Evidence from acceptability and self-paced reading experiments demonstrates that (i) judgments and processing times for Superiority violations vary in parallel, as determined by the kind of wh-phrases they contain, (ii) judgments increase with exposure, while processing times decrease, (iii) reading times are highly predictive of acceptability judgments for the same items, and (iv) the effects of the complexity of the wh-phrases combine in both acceptability judgments and reading times. This evidence supports the conclusion that D-linking effects are likely reducible to independently motivated cognitive mechanisms whose effects emerge in a wide range of sentence contexts. This in turn suggests that Superiority effects, in general, may owe their character to differential processing difficulty

Doing politics in the recent Arab uprisings: Towards a political discourse analysis of the Arab Spring slogans

The present paper aims to analyse a number of those slogans collected from the sit-in quarters in Egypt, Libya and Yemen. Using political discourse analysis, it unravels various typical discourse structures and strategies that are used in slogans in the construction of a sub-genre of political discourse in the Arab world. Drawing data from several mediums, including banners, wall graffiti, audio-visual instruments, chanting, speeches and songs, this paper tries to show the extent to which the slogans serve as a medium by which political complaints and comments are dispensed and consumed. This paper draws on a rhetorical analysis to find out their persuasive effect on shaping the Arab intellect and on the change of the political atmosphere in the region. Lastly, this paper attempts to show to what extent the slogans meet the standards of political discourse and whether they can be considered as a sub-genre of political discourse or not.IS

Time-resolved crystallography using the Hadamard transform

YesWe describe a method for performing time-resolved X-ray crystallographic experiments based on the Hadamard transform, in which time resolution is defined by the underlying periodicity of the probe pulse sequence, and signal/noise is greatly improved over that for the fastest pump-probe experiments depending on a single pulse. This approach should be applicable on standard synchrotron beamlines and will enable high-resolution measurements of protein and small-molecule structural dynamics. It is also applicable to other time-resolved measurements where a probe can be encoded, such as pump-probe spectroscopy.Wellcome Trust 4-year PhD program “The Molecular Basis of Biological Mechanisms” 089312/Z/09/Z.

Weighing up Exercises on Phrasal Verbs: Retrieval Versus Trial-And-Error Practices

EFL textbooks and internet resources exhibit various formats and implementations of exercises on phrasal verbs. The experimental study reported here examines whether some of these might be more effective than others. EFL learners at a university in Japan were randomly assigned to four treatment groups. Two groups were presented first with phrasal verbs and their meaning before they were prompted to retrieve the particles from memory. The difference between these two retrieval groups was that one group studied and then retrieved items one at a time, while the other group studied and retrieved them in sets. The two other groups received the exercises as trial-and-error events, where participants were prompted to guess the particles and were subsequently provided with the correct response. One group was given immediate feedback on each item, while the other group tackled sets of 14 items before receiving feedback. The effectiveness of these exercise implementations was compared through an immediate and a 1-week delayed post-test. The best test scores were obtained when the exercises had served the purpose of retrieval, although this advantage shrank in the delayed test (where scores were poor regardless of treatment condition). On average 70% of the post-test errors produced by the learners who had tackled the exercises by trial-and-error were duplicates of incorrect responses they had supplied at the exercise stage, which indicates that corrective feedback was often ineffective
