Research on multimedia learning has shown that learning is hampered when a multimedia message includes extraneous information that is not relevant for the task, because processing the extraneous information uses up scarce attention and working memory resources. However, eye-tracking research suggests that task experience might be a boundary condition for this negative effect of extraneous information on learning, because people seem to learn to ignore task-irrelevant information over time. We therefore hypothesised that extraneous information might no longer hamper learning when it is present over a series of tasks, giving learners the chance to adapt their study strategy. This hypothesis was tested in three experiments. In experiments 1a/1b, participants learned the definitions of new words (from an artificial language) that denoted actions, with matching pictures (same action), mismatching pictures (another action), or without pictures. Mismatching pictures hampered learning compared with matching pictures. Experiment 2 showed that task experience may indeed be a boundary condition to this negative effect on learning: the initial negative effect was no longer present when learners gained experience with the task. This suggests that learners adapted their study strategy, ignoring the mismatching pictures. That hypothesis was tested in experiment 3, using eye tracking. Results showed that attention to the pictures waned with task experience, and that this decrease was stronger for mismatching than for matching pictures. Our findings demonstrate the importance of investigating multimedia effects over time and in relation to study strategies.  相似文献

This study investigated the students’ learning process of the concept of concentration at the elementary school level in Taiwan. The influence of different representational types on the process of proportional reasoning was also explored. The participants included nineteen third-grade and eighteen fifth-grade students. Eye-tracking technology was used in conducting the experiment. The materials were adapted from Noelting’s (1980a) “orange juice test” experiment. All problems on concentration included three stages (the intuitive, the concrete operational, and the formal operational), and each problem was displayed in iconic and symbolic representations. The data were collected through eye-tracking technology and post-test interviews. The results showed that the representational types influenced students’ solving of concentration problems. Furthermore, the data on eye movement indicated that students used different strategies or rules to solve concentration problems at the different stages of the problems with different representational types. This study is intended to contribute to the understanding of elementary school students’ problem-solving strategies and the usability of eye-tracking technology in related studies.  相似文献

This study employed eye-tracking technology to probe the online reading behavior of 52 advanced L2 English learners. These participants read an e-book containing six types of multimedia supports for either vocabulary acquisition or comprehension. The six supports consisted of three micro-level supports that provided information about specific words (glosses, vocabulary focus, and footnotes), and three macro-level supports that provided global or background information (illustrations, infographics, and photos). The participants read the ebook under two presentation modes: (1) simultaneous mode: where digital input and supports were presented at the same time; and (2) sequential mode: where the digital content and supports were incrementally presented. Analyses showed that when reading for vocabulary acquisition, vocabulary focus and glosses were significantly fixated on, and when reading for comprehension, illustrations were more intensely fixated on. Additionally, when the digital content was incrementally presented, vocabulary focus received significantly higher total fixation duration. This suggests that reading under the sequential mode has the potency to guide L2 learners’ focal attention toward micro-level supports. In contrast, under the simultaneous presentation mode, L2 learners seemed to divide their focal attention among both micro-level and macro-level supports. Pedagogical implications are discussed based on the findings of this study.  相似文献

Twenty-eight sign language interpreters participated in a battery of tests to determine if a profile of cognitive, motor, attention, and personality attributes might distinguish them as a group and at different credential levels. Eight interpreters held Level II and nine held Level III Virginia Quality Assurance Screenings (VQAS); the other 11 held Registry of Interpreters for the Deaf (RID) certification. Six formal tests, the Quick Neurological Screening Test-II, the Wonderlic Personnel Test, the Test of Visual-Motor Skills (TVMS), the d2 Test of Attention, the Integrated Visual and Auditory Continuous Performance Test, and the Sixteen Personality Factor Questionnaire (16PF), were administered to the interpreters. Average scores were high on most of the tests; differences across the three groups were not statistically significant. Results from only one test, the d2 Test of Attention, were significantly correlated with interpreter level. Comparisons between educational and community interpreters also revealed no differences. Personality traits were widely distributed, but one trait, abstract reasoning, tested extremely high in 18 interpreters. Discussion of the potential implications of these results, particularly for educational interpreters, is offered.  相似文献

Abstract

An attempt was made to extend and clarify prior research which had demonstrated consistently that changed answers to objective test items tend to be correct. Results extended the basic effect of profiting from changed answers to Air Force personnel responding to multiple-choice questions regarding technical skills; the profit from changes was very similar to that observed in a university group responding to relatively "academic" items. Secondly, most individuals in both groups profited from changes. Third, individuals with the highest test scores tended to profit more from changes than those with the lowest test scores. Fourth, neither Airman Qualifying Exam scores (for the military personnel) nor Scholastic Aptitude Test scores (for the university students) were related to profit. Finally, a systematic case against the popular belief that one should not change answers on objective tests was made, based on an integration of the research to date.  相似文献

The eye-tracking technology was used in this study to investigate the effects of embedded questions and feedback in instructional videos on learning performance and attention allocation and whether an expertise reversal effect existed. The experiment involved 49 learners with high-level prior knowledge and 45 ones with low-level prior knowledge from a university. Meanwhile, they learned instructional videos with no embedded feedback, embedded questions without feedback and embedded questions with feedback. Findings from the experiment showed that the instructional videos with embedded questions but without feedback not only improved the participants’ attention but also enhanced their learning performance. Furthermore, there was an expertise reversal effect on the learning performance whereby instructional videos with embedded questions but without feedback improved the learning performance of learners with low-level prior knowledge, but not those with high-level prior knowledge.  相似文献

The relationship between the construct of mental attention and “giftedness” is not well established. Gifted individuals could make effective use of their executive functions and this could be related to their mental attentional capacity. The dialectic constructivist model developed by Pascual-Leone introduced the concept of mental attention or “effort”, relating it to mental capacity. The aim of this study is to investigate whether the measurement of mental capacity (M-measurement) is differential for a group of children with high IQs. 110 students between 4 and 18 years old participated in this study. Some were Gifted (n=70) and others Non-Gifted (n=40). Wechsler-R Scale and the Figural Intersection Test were administered to all participants. An interesting pattern was found in the younger groups. The gifted scored higher than the non-gifted in the Figural Intersection Test and much higher than their theoretical M. The non-gifted scored quite close to their theoretical M (based on age). In the oldest group, the gifted again achieved higher scores, but now they scored at the theoretical level, and the non-gifted underperformed.  相似文献

ABSTRACT

Objectives: This study aims to test the dimensionality, reliability, and item quality of the revised UCLA loneliness scale as well as to investigate the differential item functioning (DIF) of the three dimensions of the revised UCLA loneliness scale in community-dwelling Chinese and Korean elderly individuals.

Method: Data from 493 elderly individuals (287 Chinese and 206 Korean) were used to examine the revised UCLA loneliness scale. The Research model based on item response theory (IRT) was used to test dimensionality, reliability, and item fit. The hybrid ordinal logistic regression-IRT test was used to evaluate DIF.

Results: Item separation reliability, person reliability, and Cronbach’s alpha met the benchmarks. The quality of the items in the three-dimension model met the benchmark. Eight items were detected as significant DIF items (at α < .01). The loneliness level of Chinese elderly individuals was significantly higher than that of Koreans in Dimensions 1 and 2, while Korean elderly participants showed significantly higher loneliness levels than Chinese participants in Dimension 3. Several collected demographic characteristics and loneliness levels were more highly correlated in Korean elderly individuals than in Chinese elderly individuals.

Conclusion: Analysis using the three dimensions is reasonable for the revised UCLA loneliness scale. Good item quality and the items of this measure suggest that the revised UCLA loneliness can be used to assess the preferred latent traits. Finally, the differences between the levels of loneliness in Chinese and Korean elderly individuals are associated with the factors of loneliness.  相似文献

The onset of motion was used to study stimulus-driven visual attention in 14-week-olds. The movement of an object did not capture attention reflexively at 14 weeks of age. The attention-getting properties of a moving stimulus depended significantly on its color in combination with the colors of other objects in the visual field. Specifically, detection of a green moving target was masked in the presence of mixed red and green static objects. No such masking was observed when the moving target was red or when the green target moved in a visual field that was populated only with green objects. The same effect was observed to a lesser extent when the green bars were replaced with gray bars. The number of distractors in the visual field exerted an effect on the accuracy of detection only when their appearance in the visual field was coincident with the onset of target motion. Attention to motion at this age is not independent of the structure of the visual field; chromatic preferences play a role in how readily infants attend to a moving object. These effects may be mediated by a difficulty in disengaging attention (from distractors) or in suppressing attention to competing objects once attention is engaged on a target.  相似文献

This study utilized qualitative and quantitative designs and eye-tracking technology to understand how viewers process multimedia information. Eye movement data were collected from eight college students (non-science majors) while they were viewing web pages containing different types of text and illustrations depicting the mechanism of atmospheric pressure and the formation of sea and land winds. The results showed that participants' eyes were fixated more often on the text than on the illustrations. Breaking the instructional multimedia into small successive segments did not seem to increase the number of eye fixations on the illustrations. Participants alternated their eye fixations on related components of the illustrations while focusing on verbs or sentences representing the kinematics of the weather systems. Text seemed to provide more detailed explanations than pictures and therefore served as the main resource for understanding the content. Scan paths revealed that participants were likely to be distracted by decorative icons in the illustrations. The decorative icons also created a split-attention effect on students' cognitive processing. Eye-tracking technology was found to be a valuable tool for achieving the objectives of this study, and it provided insights into students' cognitive processes during multimedia learning. Discussion and suggestions for instructional designers and future studies are provided.  相似文献

Three experiments with students from 7th and 8th grade were performed to investigate the effects of decorative pictures in learning as compared to instructional pictures. Pictures were considered as instructional, when they were primarily informative, and as decorative, when they were primarily aesthetically appealing. The experiments investigated, whether and to what extent decorative pictures affect the learner’s distribution of attention, whether they have an effect on the affective and motivational state and whether they affect the learning outcomes. The first experiment indicated with eye-tracking methodology that decorative pictures receive only a bit initial attention as part of the learner’s initial orientation and are largely ignored afterwards, which suggests that they have only a minor distracting effect if any. The second experiment showed that despite the small amount of attention they receive, decorative pictures seem to induce better mood, alertness and calmness with learners. The third experiment indicated that decorative pictures did not intensify students’ situational interest, but reduced perceived difficulty of the learning material. Regarding outcomes of learning, decorative pictures were altogether neither harmful nor beneficial for learning. However, they moderated the beneficial effect of instructional pictures––in essence: the multimedia effect. The moderating effect was especially pronounced when learners had lower prior knowledge. The findings are discussed from the perspective of cognitive, affective and motivational psychology. Perspectives of further research are pointed out.  相似文献

The results of qualitative and quantitative investigations conducted with individuals who learned algorithms in school are presented in this article. In these investigations, eye-tracking technology was used to follow the process of solving algorithmic problems. The algorithmic problems were presented in two comparable variants: in a pseudocode and flowchart. The eye-tracking data resulted in both qualitative (films registering the gaze paths) and quantitative measures, which allowed the detection and interpretation of the differences in the task-solving strategies between those who found the correct answer and those that did not. The results confirmed a hypothesis that use of the formal notation characteristic of a programming language for presenting algorithms is often a practical difficulty in the process of solving even simple tasks. This study opens a new direction of research; they show that eye-tracking technology can be used to optimise the educational process of learning programming.  相似文献

Attention acts as the mind's “gatekeeper” by regulating and prioritizing the stimuli processed by the central nervous system. It is essential for cognitive performance, memory, and behavior, and we know that even slight deficiencies in attention compromise learning. Basic neuroscience research further indicates that attention consists of (fairly) independent subcomponents, which rely on distinct neural structures, and serve different functions in everyday behavior. Disturbances of brain function, such as those suggested to be related to learning disabilities, may lead to different patterns of attention performance (i.e., some attention systems may work sufficiently well, while others are substantially impaired). The present experiment describes a pilot study that aimed to characterize the extent and range of individual variations in attention performance in persons classified as learning disabled. Specifically, we tested the hypothesis that attention is not uniformly impaired in these individuals. Rather, we expected some subcomponents to be more severely impaired than others, and substantial heterogeneity in the individual “deficit patterns.”The Test of Everyday Attention (TEA) was used to assess visual selective attention, attentional switching, sustained attention, and auditory–verbal working memory in students with nondyslexic learning disability (LD group) and matched controls. The group comparison revealed a significantly weaker performance in the LD group. Analysis of subtest-specific scaled scores further indicated great individual differences in the performance pattern. Thus, in each student with LD, we found normal performance in at least two subtests, while other subcomponents where severely impaired. The study supports the idea of differential attention deficits in the learning disabled, and suggests individual patterns of “strengths and weaknesses.” Taking the relationship of attention and learning into account, this finding is important with respect to the design of individual learning programs and the teaching techniques chosen for the acquisition of skills and knowledge.  相似文献

ABSTRACT

Research on teacher education, especially on the development of teacher educators, is limited. This paper considers the role of dispositions in the development of pedagogical knowledge (PK) for science teacher educators (STEs), across stages of career. It argues that beliefs and perceptions shift and change along with, but not directly related to, what STEs pay attention to and when they pay attention to it. The eight participants were asked to identify the critical experiences (CEs) of their career that impacted on their development of PK. CEs were analyzed using Morine-Dershimer and Kent’s (1999) model of PK as a framework, but also to identify common emergent themes across participants and common emergent themes for individuals that led to identification of patterns of actions and finally, participant’s dispositions. The notion that beliefs, dispositions and PK are all developed for each individual at their own pace and in their own way is reinforced.  相似文献

The paper provides (1) a teacher-administered rating instrument for inattention without confounding the rating with hyperactivity and conduct disorder, and (2) evidence that the ratings correlate with the scores obtained from cognitive tests of attention. In Study I, the first objective was to investigate the construct validity and the inter-rater reliability of the Attention Checklist (ACL) by factor analysing the teacher ratings of 110 Grade 4 children, obtained by using the ACL. The second objective was to investigate the predictive validity of the ACL by examining the relationship between the scores obtained for the participants from teachers' ratings using the ACL and the scores obtained by participants in the lab-type attention tests. The results of factor analysis showed that a single factor labelled ‘inattention’ underlies the 12 items in the ACL. Examining the differences in performance on attention tests, the ‘low attention’ children as rated by the teachers on the ACL scored lower than the ‘high attention’ children on the objective tests of attention. These findings were replicated in Study II, which was conducted to test further the construct validity and predictive validity of the ACL. This time, only those two tests (Auditory Attention and Visual Attention) that had shown relatively poor discrimination between the high and low attention groups in Study I were, again, administered to another cohort of 97 Grade 4 children, as it was our intention to further challenge the reliability of the ACL. Overall, the results of both studies suggest that comprehensive assessment of attention skills should include both ACL and objective measures of selective attention.  相似文献

ABSTRACT

A main objective of classroom management (CM) is to raise students’ attention to their daily academic work by creating a classroom environment that supports academic and socioemotional learning. While studies have addressed CM effects on classroom-level behaviour or students’ academic outcomes, students’ attention skills been largely overlooked. This randomized controlled trial evaluates the effectiveness of a teacher-targeted CM intervention on students’ selective attention. Twenty-four primary schools were randomized into receiving the Inclusive And Appreciative Classroom Management (IACM) intervention (treatment) or a general information technology (IT) didactics course (control condition). All participating 1st-grade teachers and their students (N = 1,160) were followed for 1 year. Using repeated measurements of the d2 Test of Attention, we find that the IACM intervention improves students’ selective attention with .26 standard deviations. The effect is robust to the inclusion of student- and classroom-level characteristics. All analyses account for the variation across students, classrooms, and schools.  相似文献

The Continuous Performance Test (CPT), such as the Test of Variable Attention (TOVA), is widely used in the assessment of ADHD with other behavioral ratings and observations. Since some clinicians argue that CPTs measure psychomotor speed function rather than sustained attention, a correlation study between PIQ of WISC‐III and TOVA was conducted to find out if a significant relationship of any kind existed. Forty children with ADHD were studied, and the results indicated that there was no correlation between TOVA and PIQ of WISC‐III. © 1999 John Wiley & Sons, Inc.  相似文献

Children with attention deficit hyperactivity disorder (ADHD) were examined on four subtests of the Test of Everyday Attention for Children (TEA‐Ch) when on and off stimulant medication. Performance was assessed relative to 18 individually age‐matched controls. Children with ADHD performed significantly worse on TEA‐Ch measures when off compared to when on stimulant medication. This was found in both predominantly inattentive (n = 6) and combined inattentive and hyperactive‐impulsive (n = 12) subtypes. The age‐matched controls significantly improved with repeated testing on most TEA‐Ch measures. Significant differences were found between the unmedicated children with ADHD and age‐matched controls on sustained attention (Score! and Walk Don’t Walk) and attention control measures (Same and Opposite Worlds). When the ADHD group was on stimulant medication, with the exception of the Walk Don’t Walk subtest, no significant differences were found between them and the age‐matched controls. Unlike the TEA‐Ch subtests, the significant differences between the two groups on the Test of Word Reading Efficiency (TOWRE) subtests remained when attentional status was altered in the children with ADHD. The study supports further investigations of the TEA‐Ch as a measure sensitive to changes in stimulant medication in children with ADHD.  相似文献
