This study investigated electroencephalographic differences between two groups of children with attention-deficit/hyperactivity disorder, combined type, with reading disabilities (ADHD + RD) or without (ADHD) and typical control participants. Twenty participants were included in each group. All participants were between the ages of 8 and 12 years, and groups were matched on age and gender. The electroencephalographic (EEG) was recorded during an eyes-closed resting condition from 21 monopolar derivations, which were clustered into nine regions for analysis. The EEGs were Fourier-transformed to provide absolute and relative power estimates for the delta, theta, alpha, and beta bands. Ratio coefficients were also calculated for the theta/alpha and theta/beta ratios. Compared with controls, the clinical groups demonstrated the increased slow-wave and reduced fast-wave activity commonly reported in the ADHD literature. The ADHD + RD group had more relative theta, less relative alpha, and a higher theta/alpha ratio than the ADHD group. A number of hemispheric differences were also found in the delta and alpha bands. These results suggested that some of the EEG divergences found in the ADHD + RD group represent an electrophysiological component associated with the reading disability that is independent of the EEG divergences found in ADHD.  相似文献

This article presents an experimental study of the assessment made by university students of their level of digital competence in the use of mobile devices such as smartphones, laptops and tablets. The study was part of an investigation into ubiquitous learning with mobile devices and is based on the analysis of responses from a sample of 203 university students at eleven European and Latin American universities. Participants were asked questions about their performance on a set of digital activities that tested various components of digital competence. The analysis methodology was based on Item Response Theory (IRT). The survey data was analysed by applying a statistical model to represent the probability of obtaining an affirmative answer to each activity proposed. This enabled us to identify the difficulty and discrimination parameters of each activity. As an outcome of the study, measures on latent digital competence in individual participants were articulated. The results allowed us to describe how a number of devices and activities interacted. Understanding these types of interactions is necessary for a continued development of the evaluation of digital competence in students.  相似文献

This study examined how timing (i.e., relative maturity) and rate (i.e., how quickly infants attain proficiency) of A‐not‐B performance were related to changes in brain activity from age 6 to 12 months. A‐not‐B performance and resting EEG (electroencephalography) were measured monthly from age 6 to 12 months in 28 infants and were modeled using logistic and linear growth curve models. Infants with faster performance rates reached performance milestones earlier. Infants with faster rates of increase in A‐not‐B performance had lower occipital power at 6 months and greater linear increases in occipital power. The results underscore the importance of considering nonlinear change processes for studying infants’ cognitive development as well as how these changes are related to trajectories of EEG power.  相似文献

The patterns of brain activation during norm-referenced and criterion-referenced feedback were compared, using the functional magnetic resonance imaging (fMRI). Twenty-two healthy right-handed individuals performed a series of perceptual judgment tasks while their brain activity was recorded. The participants responded to a performance-approach goal survey and performed practice trials prior to scanning, during which their perceived competence toward the novel task was manipulated with bogus performance information. During scanning, the participants received either norm-referenced or criterion-referenced feedback after each performance. The brain regions associated with negative affect including the posterior cingulate cortex, the medial frontal gyrus, and the inferior parietal lobule were recruited during norm-referenced feedback only among the low-competence participants. In contrast, significant activation was observed in the identical cortical areas involved in negative affect during criterion-referenced feedback only among the high-competence participants. Regardless of the level of perceived competence, performance-approach goal scores correlated positively with activation in the brain areas implicated in the negative emotion during norm-referenced feedback. The present findings provide insight into the potential costs and benefits of normative assessment.  相似文献

This study sought to understand how teachers' discomforting emotions were manifest in a teacher education setting and how teacher educators might engage with discomfort pedagogically. A qualitative perspective was used with a group of teachers who participated in a series of peace education workshops in Cyprus. All of the workshops were audio- and video-recorded; in-depth interviews were also conducted with seven focal participants before and after the workshops. The findings show the manifestations of discomfort, the sources of discomfort, and the ways of handling teachers' discomfort pedagogically. The paper discusses how this study may inform teacher education.  相似文献

It was investigated how domain-specific knowledge, fluid intelligence, vocational interest and work-related self-efficacy predicted domain-specific problem-solving performance in the field of office work. The participants included 100 German VET (vocational education and training) students nearing the end of a 3-year apprenticeship program as an industrial clerk (n?=?63) which usually leads to a position in office work, lower or middle management, or a similar apprenticeship program to become IT-systems management assistants (n?=?37). The participants worked on three computer-based problem scenarios dealing with operative controlling, a relevant domain to both training occupations, and completed further assessments to measure the variables listed above. Theoretical considerations, prior research and domain analyses suggested that industrial clerks would have greater domain-specific problem-solving competence (H1a) and domain-specific knowledge (H1b) than IT-systems management assistants and that domain-specific knowledge would be the strongest predictor of problem-solving competence (H2: “knowledge-is-power” hypothesis); all hypotheses were confirmed. Hypothesis 3, the “Elshout-Raaheim hypothesis,” predicts that fluid intelligence and problem-solving competence are most strongly correlated in the context of intermediate levels of task-related content knowledge, however the highest correlation was found in the group with low domain-specific knowledge. The findings suggest that intelligence plays a minor role in later stages of competence development whereas typical problem situations in later stages particularly require prior knowledge. The relationship of intelligence, knowledge and problem solving as well as limitations of the study, particularly weaknesses in the measurement of non-cognitive dispositions, are discussed.  相似文献

The current scales for self-blame are not suitable for school bullying scenarios and most lack validity. This study used a self-developed scale to measure bullied victims’ tendency to self-blame and further examined whether victims and bully/victims exhibited different tendencies toward self-blame under both bullied and generalized scenarios. The study consisted of 1,320 student participants from grades five to nine. The research instrument was a self-constructed bullied-victim self-blame scale (BSS), and the results were analyzed using the Rasch rating scale model. The Rasch results showed strong evidence of BSS reliability and validity. The results indicated that participants’ self-blaming tendency scores were positively correlated with depression (= .31). In addition, participants’ self-blaming scores in relational bullying were higher than those in verbal and physical bullying. The self-blaming tendency of bully/victims under bullied scenarios was higher than that of victims, but no difference was found between bully/victims and victims for generalised scenarios. The participants’ tendency to self-blame under generalised scenarios was significantly higher than under bullied scenarios. The tendencies of various roles to self-blame under different scenarios and the self-blaming counselling strategies for victims are discussed at the end of this study.  相似文献

This study aimed to investigate the developmental dynamics between children's mathematical performance, the task-focused versus task-avoidant behaviours they show in the classroom, and their parents' beliefs concerning their school competence. The mathematical performance of 111 six- to seven-year-old children was tested, and their task-focused versus task-avoidant behaviours were rated by their teachers four times during their first school year. Parents filled in questionnaires measuring their skill-specific and general beliefs about their children's school competencies at the beginning and at the end of the school year. The results showed that parents' beliefs in their children's general school competence increased their children's task-focused behaviours at school, which further predicted the child's high level of maths performance. Parents' beliefs in their children's competence in mathematics, in turn, contributed directly to the children's high mathematical performance. Moreover, children's high performance increased parents' subsequent beliefs in their children's mathematical competence, whereas children's task-focused behaviours predicted parents' beliefs in their children's overall school performance.  相似文献

This study investigated the cognitive processes involved in learning information presented in multimedia and text format using electroencephalographic (EEG) measures. Thirty-eight students (19 gifted, and 19 average) learned material presented with text (text); text, sound, and picture (picture); and text, sound and video (video), while their EEG was recorded. Alpha power, which is inversely related to mental effort, was analyzed. For thetext presentation, the alpha power measures showed higher amplitudes (less mental activity) over the occipital and temporal lobes, and less alpha power (higher mental activity) over the frontal lobes. The results support the assumption that thevideo andpicture presentations induced visualization strategies, whereas thetext presentation mainly generated processes related to verbal processing. The results further showed that gifted students displayed less mental activity during all three formats of presentation. These differences were especially pronounced for thevideo format. No gender-related differences in EEG patterns related to the format of presentation were observed.  相似文献

Diagnosing is one of teachers’ key competences. Lately, a new model of teachers’ diagnostic competence and therewith a new measurement method focusing on diagnosing students’ learning behavior in an interdisciplinary approach have been developed. They can build a basis for promoting teachers’ diagnostic competence. However, some questions relevant to promoting teachers’ diagnostic competence concerning students’ learning behavior still remain unanswered: Which values do teachers-on-the-job in contrast to preservice teachers with or without teaching experience gain through experience and which are the relevant variables that lead to a high level of diagnostic competence focused on learning behavior? Thus, this study aims at enlightening these issues. In a sample of 293 participants (93 German grammar school teachers, 107 German teacher students in their second phase of teacher education, and 93 German preservice students in their first phase of teacher education), teachers’ diagnostic competence concerning learning behavior as well as teachers’ motivation, attitude, self-efficacy, knowledge, and reflection on experience concerning diagnosing was measured. Motivation, attitude, and knowledge were found to be substantial positive predictors of diagnostic competence concerning learning behavior, with differentiated predictions for teachers’ experience. Reflection on experience and self-efficacy unexpectedly was not found to be relevant. Teachers-on-the-job were generally better at diagnosing their students’ learning behavior than were preservice teachers without teaching experience. However, the diagnostic work of preservice teachers with teaching experience was as credible as that of the in-service teachers.  相似文献

A new approach to moral education using blended learning has been developed. This approach involves 10 scenarios that are designed as a web-based game and serves as a basis for group moral-consequence-based reasoning, which is developed based on a hypothetical-deductive model. The aim of the study was to examine the changes in students' blended learning interest and reasoning ability in a time series experimental design. After playing the game with the 10 initial scenarios during the first week of the study, participants were subjected to five blended learning sessions that required them to discuss the consequences of one of the 10 scenarios using hypothetical-deductive reasoning. After six weeks, the data from the 110 participants were analyzed using time series statistics. The results indicated that players were highly interested in the game, although their interest had a tendency to decrease slightly over time. Repetitive game play (i.e. practice) was positively associated with the players' moral reasoning performance. The study results may lend support to the design of a game with additional or more highly complex content for players to further develop students' consequential reasoning ability.  相似文献

The purpose of this study was to investigate the relationship between motor competence and BMI in Hispanic preschool children from low SES backgrounds. One hundred and forty-eight Hispanic low SES preschool children (male = 81, female = 67 participated in this study. All children were measured on gross and fine motor competence using the Peabody Developmental Motor Scales-2 (PDMS-2). Body Mass Index (BMI) was calculated for all participants. A Pearson correlation was used to analyze the relationship between the preschool children’s BMI and PDMS-2 performance. A 2 (gender) × 3 (BMI) MANOVA was conducted to assess the gender and BMI differences on each PDMS-2 subtest. Nearly one-third of children in the study demonstrated gross and fine motor delays and slightly over one-third of the children were classified as overweight or obese. A significant negative correlation was found between BMI and visual motor integration scores. The MANOVA analysis showed that low SES Hispanic boys were significantly better in gross motor skill competence and girls were more advanced in fine motor performance. These findings will make a significant contribution to the literature in identifying relationship between motor competence and children’s body weight. This study is also beneficial to practitioners and educators in designing intervention and preschool curriculum to improve children identified with motor delays and to reduce BMI through physical activity.  相似文献

Reflection on events at work, including errors is often as a means to learn effectively through work. In a cross-sectional field study in the banking sector, we investigated attitudes towards workplace errors (i.e. error orientation) as predictors of reflective activity. We assumed the organisational climate for psychological safety to have a mediating effect. The study participants were 84 client advisors from the retail banking departments in branches of a German bank. The client advisors’ were being affected by a range of changes in their workplaces at the time of the data collection. This situation afforded these workers opportunity for learning but also involved the risk of error by these staff. Regression analyses identified that error competence and learning from errors were significant predictors of reflection. The results confirmed the mediating role of psychological safety on the association between attitudes towards errors and reflective working behaviour.  相似文献

The present study investigates the nature of Iranian student teachers’ reflections and their professional development in the context of teacher education practicums. The participants were student teachers (N = 41) enrolled in teacher education colleges at Farhangian University in Tehran, Iran. A total of 620 reflective writing excerpts were coded using deductive content analysis across three cohorts in three different practicums during a two-year period. To analyse the data, this study applied a rubric for evaluating student teachers’ reflections developed by Ward and McCotter. The analysis also involved Friedman’s test and follow-up Wilcoxon tests. The results show that routine levels of reflection significantly decreased across the three practicums, while technical levels of reflection significantly increased. The higher levels of reflection, namely dialogic and transformative levels, were rarely found in student teachers’ reflective writings across the practicums. This study discusses the need both to develop appropriate methods to guide student teachers in centralized contexts such as Iran and to investigate further aspects that enhance or hinder progress in the quality of reflection in teacher education.  相似文献

Objective: The functional relationship between calculated alpha band spectral power and inter-/intra-hemispheric coherence during a three-level working memory task of patients with mild cognitive impairment (MCI) was investigated. Methods: Subjects included 35 MCI patients according to the DSM-IV criteria (mean age: 62.3, SD: 6.5) and 34 healthy controls (mean age: 57.4, SD: 4.0) were selected from the community at large. All subjects performed a simple calculation and recall task with three levels of working memory load while electroencephalograph (EEG) signal was recorded. The spectral EEG power was computed over alpha1 (8.0~10.0 Hz) and alpha2 (10.5~13.0 Hz) frequency bands and was compared between rest stage and working memory processing stage by two-way ANOVA. Post hoc testing analyzed the differences between each two levels of working memory load during task processing. The inter-hemisphere EEG coherence of frontal (F3-F4), central (C3-C4), parietal (P3-P4), temporal (T5-T6) as well as occipital (O1-O2) was compared between MCI patients and normal controls. The EEG signals from F3-C3, F4-C4, C3-P3, C4-P4, P3-O1, P4-O2, T5-C3, T6-C4, T5-P3 and T6-P4 electrode pairs resulted from the intra-hemispheric action for alpha1 and alpha2 frequency bands. Result: There was significantly higher EEG power from MCI patients than from normal controls both at rest and during working memory processing. Significant differences existed between rest condition and three-level working memory tasks (P<0.001). The inter-and intra-hemispheric coherence during working memory tasks showed a "drop to rise" tendency compared to that at rest condition. There was significantly higher coherence in MCI patients than in the controls. When task difficulties increased, the cortical connectivity of intra-hemispheric diminished while the inter-hemispheric connectivity dominantly maintained the cognitive processing in MCI patients. Conclusion: The results of the present study indicate that the alpha frequency band may be the characteristic band in distinguishing MCI patients from normal controls during working memory tasks. MCI patients exhibit greater inter-hemispheric connectivity than intra-hemispheric connectivity when memory demands increase. MCI patients mobilize a compensatory mechanism to maintain the processing effectiveness while the processing efficiency is reduced.  相似文献

This article considers the relationship between differential homework task difficulty, student engagement and performance across four Irish post-primary school sites. A total of 236 participants completed all elements of this study. All participants were junior cycle students, aged between 12 and 16 years. The study employed a standardised test–retest approach, with a one week interval between tests. Between testing, participants were randomly subdivided into three cohorts. Each cohort received homework questions of different difficulty levels to complete for one week. The results of this study found that Cohort A, who received the least difficult homework tasks, completed the most non-compulsory questions. Although Cohort A demonstrated higher levels of engagement, no statistically significant difference was found in the change in performance scores of the three cohorts. The results highlight the negative impact of increased task difficulty on student engagement with independent homework tasks. The findings suggest that in order to support student engagement it is important that teachers afford ample opportunity for student success when designing self-directed tasks such as homework.  相似文献

An important purpose of higher social work education is to guide students to acquire and develop social-communicative competencies. The purpose of this study was to investigate the role students’ personality characteristics, self-perceived communicative competence and learning conceptions play in the acquisition and development of social-communicative competencies. We designed and tested a hypothetical model on the student-related variables – self-perceived communicative competence, learning conceptions and reported learning activities regarding communication – in relation to performance scores. We were interested in developmental trends in the above mentioned variables. We also wanted to gain insight into the relationships among the variables. The study was set up according to a longitudinal, within-subjects design in order to study intra-individual changes. One-hundred and twenty-three first-year social-work students participated in this study. Many changes were found in students characteristics, reported deployed learning activities and study results during their first academic year. Except for confidence in “showing sympathy”, which was already relatively high at the beginning of the study, all scores on aspects of students’ self-perceived social-communicative competence increased. Assessment scores on comparable communication tests also increased significantly. Extraversion and emotional stability were the only two personality characteristics, which seemed rather stable. Agreeableness decreased while autonomy increased continuously during the first academic year. It seemed to be possible to set up a model, which may serve as a starting point for further research into the development of social-communicative competence.  相似文献

This study aims to explore the digital natives among a sample of pre-service teachers and in the process, examine the validity of a Turkish adaptation of the digital native assessment scale (DNAS) [Teo, T., & Fan, X. (2013). Coefficient alpha and beyond: Issues and alternatives for educational research. The Asia-Pacific Education Researcher, 22(2), 209–213]. Five hundred and fifty-seven participants completed a survey questionnaire in Turkish measuring their responses on the DNAS, developed from a proposed four-factor research. Confirmatory factor analysis and multiple indicators, multiple causes modelling were used to analyse the data and an acceptable fit was found, suggesting that the DNAS is a valid measure for participants who are older living in another culture. While the pre-service teachers had mostly regarded themselves as digital natives, significant differences were only found by years of computer use and perceived competence but no significant differences were found for gender and age.  相似文献

In this paper, we investigate university lecturers’ experiences of and reflections on the development of their pedagogical competency during a 9-month university pedagogical course. The effects of long-term university pedagogical training are considered through experienced pedagogical competency by analysing university lecturers’ evaluations of and reflections on their pedagogical competence areas during the course. Data was gathered from 31 participants using a self-evaluation questionnaire and reflective writings, and analysed using a mixed-methods approach. The results show that the participants experienced significant development in their pedagogical competency. However, it became evident that the concept and practice of reflection is not clear, especially in different disciplines. In addition to the number of credits of the training, the design, and the long timeframe of the pedagogical training, the context in which the training is put into practice, as well as the social aspect of reflection, need to be taken into consideration.  相似文献
