Effects of tactile training on visual speechreading: performance changes related to individual differences in cognitive skills

We report on a follow-up study of the R?nnberg, Andersson, Lyxell, & Spens (1998) speech tracking training study. The purpose was to examine, initially and after training, the effects of different tactile aids on tasks of visual speechreading. We also examined cognitive prerequisites for initial baseline speechreading and posttraining speechreading performance. Compared with speechreading alone, tactile aids impaired sentence-based speechreading at first, although performance improved with training. No effects of vibrotactile aids or training were obtained for visual word-decoding. Initial baseline speechreading performance and posttraining performance correlated with cognitive skills, but the size of the correlations changed. The size of the correlations also varied with the different tactually mediated speechreading conditions.     

Assessing System Thinking Through Different Concept-Mapping Practices

System thinking is usually investigated by using questionnaires, video analysis, or interviews. Recently, concept-mapping (CM) was suggested as an adequate instrument for analysing students' system thinking. However, there are different ways with which to use this method. Therefore, the purpose of this study was to examine whether particular features of CM practices affect the valid assessment of students' system thinking. The particular features analysed were the medium (computer versus paper–pencil) and the directedness (highly directed versus nondirected) of CM practices. These features were evaluated with respect to their influence on (a) students' performance in CM and (b) the validity of different CM practices for system thinking. One hundred fifty-four German fourth graders (mean age: 9.95 years) and 93 eighth graders (mean age: 14.07 years) participated in the study following an experimental pre-test–post-test design. Three variations of CM practices were applied: (a) highly directed computer mapping, (b) highly directed paper–pencil mapping, and (c) nondirected paper–pencil mapping. In addition to the CM task, a paper–pencil questionnaire was employed to investigate the validity of the CM practices. Results showed that the computer positively influenced student performance in CM when compared with paper–pencil. By contrast, there was no difference between highly directed and nondirected mapping. Whereas the medium rarely influenced the validity of CM for system thinking, high directedness showed a positive influence. Considering the limitations and benefits of particular CM practices, we suggest highly directed and computer-based CM as an appropriate assessment tool—in particular, with regard to large-scale assessments of system thinking.     

Civic learning: moving from the apolitical to the socially just

This study examines the knowledge and skills that characterize civic learning for young people. Building on a literature review, it reports an exploratory case study with students and teachers in four secondary schools in the Ottawa, Canada region. The perspectives of researchers co‐operating with educators and students against a backdrop of provincial government curricula and secondary literature on youth citizenship engagement provide an enriched understanding of the state and potential of civic learning. It concludes that current civic learning is primarily characterized by procedural knowledge and compliant codes of behaviour that do not envelope students in collective action for systemic understandings of political issues. This study argues for renewed efforts to put social justice at the heart of student learning. To present a convincing civic educational programme, schools should prepare students to analyse power relationships, investigate the ambiguities of political issues, and embrace opportunities for social change.     

Authentic Learning in a Sociocultural Framework: A case study on non‐formal learning

This paper reports a case study in which 53 adult refugees initiated their own forms of learning with the aim of strengthening their opportunities for integration into Swedish society. The overall research interest was to find out what theoretical implications can be drawn from a case study where two different forms of learning were implemented. One alternative was offered in a formal setting and another in a non‐formal setting where the group members shaped forms of learning themselves. The findings show that many features of non‐formal working procedures correspond with basic assumptions and key concepts of sociocultural theory. Furthermore, these features accord well with key concepts of authentic learning. In a similar way as theoretical aspects of “situated learning” can be seen as an integrated part of sociocultural theory, we discuss whether the notion “authentic learning” could be used as a dimension of supporting meaningful learning in contextualised inclusive learning environments.     

The Impact of High versus Low Linguistic Levels in Swedish Beginning Readers' Oral Reading of Running Texts

The impact of high (e.g. syntax and semantics) and low (graphemes) linguistic levels in 50 Swedish beginners' oral reading of running texts is explored, by means of a qualitative analysis of reading errors collected in a longitudinal study. The hypothesis, based on previous quantitative results from the same data, was that the graphemic and/or lexical levels could explain some of the reading errors, but that, for example, syntactic complexity or unexpected contexts could explain others. Unfamiliar words and words with complex graphemic structures did result in many reading errors, but a relatively large number of errors seem to be caused by, for example, syntactical or contextual constraints. In the longitudinal perspective, the readers tended to advance through various phases regarding their utilisation of higher linguistic levels, revealing a possible transition from a concentration mainly on the graphemic level via a dependency on and finally a sensitivity to context.     

Commercially available compression garments or electrical stimulation do not enhance recovery following a sprint competition in elite cross-country skiers

This study investigated whether commercially available compression garments (COMP) exerting a moderate level of pressure and/or neuromuscular electrical stimulation (NMES) accelerate recovery following a cross-country sprint skiing competition compared with a control group (CON) consisting of active recovery only. Twenty-one senior (12 males, 9 females) and 11 junior (6 males, 5 females) Swedish national team skiers performed an outdoor sprint skiing competition involving four sprints lasting ～3–4 min. Before the competition, skiers were matched by sex and skiing level (senior versus junior) and randomly assigned to COMP (n?=?11), NMES (n?=?11) or CON (n?=?10). Creatine kinase (CK), urea, countermovement jump (CMJ) height, and perceived muscle pain were measured before and 8, 20, 44 and 68?h after competition. Neither COMP nor NMES promoted the recovery of blood biomarkers, CMJ or perceived pain post-competition compared with CON (all P?>?.05). When grouping all 32 participants, urea and perceived muscle pain increased from baseline, peaking at 8?h (standardised mean difference (SMD), [95% confidence intervals (CIs)]): 2.8 [2.3, 3.2]) and 44?h (odds ratio [95% CI]: 3.3 [2.1, 5.1]) post-competition, respectively. Additionally, CMJ was lower than baseline 44 and 68?h post-competition in both males and females (P?相似文献
