This study used a large-scale cluster randomized longitudinal experiment (N = 719; 35 schools) to investigate the effects of online mathematics mini-games on primary school students’ multiplicative reasoning ability. The experiment included four conditions: playing at school, integrated in a lesson (Eschool), playing at home without attention at school (Ehome), playing at home with debriefing at school (Ehome-school) and, in the control group, playing at school mini-games on other mathematics topics (C). The mini-games were played in Grade 2 and Grade 3 (32 mini-games in total). Using tests at the end of each grade, effects on three aspects of multiplicative reasoning ability were measured: knowledge of multiplicative number facts, skills in multiplicative operations, and insight in multiplicative number relations and properties of multiplicative operations. Through path analyses it was found that the mini-games were most effective in the Ehome-school condition, where both students’ skills and their insight were positively affected as compared to the control group (significant ds ranging from 0.22 to 0.29). In the Eschool condition, an effect was only found for insight in Grade 2 (d = 0.35), while in the Ehome condition no significant effects were found. Students’ gameplay behavior (time and effort put in the games) was in some cases, but not always, related to their learning outcomes.  相似文献

This study reports adolescent expectancy-value motivation, and its relation to fitness knowledge and psychomotor skill learning in physical education. Students (N = 854) from 12 middle schools provided data on expectancy-value motivation, fitness knowledge and psychomotor skill learning. Results from dependent t-test and MANOVA indicated that 8th grade students rated task values significantly lower than 6th grade while their expectancy beliefs did not significantly differ. Students gained sizable fitness knowledge (d = 0.58, p < 0.05) and badminton skill (d = 1.40, p < 0.05). Multiple regression analyses revealed that expectancy-value motivation did not significantly predict learning in fitness knowledge or psychomotor skills. These findings suggest that expectancy-value motivation might predict engagement and performance, but not necessarily learning achievement in physical education.  相似文献

The purpose of this study was to compare the effects of different types of questioning interventions on students' reading comprehension. Fourth-grade students (n = 246) were identified as struggling, average, or good readers and assigned randomly within school to one of three questioning interventions: two inferential conditions (Causal or General) or one literal condition (“Who, What, Where, When” or W-questioning). Teachers delivered the interventions for 20–30 min, 2–4 times per week, for 8–10 weeks. All readers made reliable pre- to posttest comprehension gains as measured by story recall (ps < .001 to .04). Differential effects for intervention were found between two subgroups of struggling comprehenders—elaborators and paraphrasers. Elaborators benefited more than paraphrasers from Causal questioning (d = .86) whereas paraphrasers benefited more than elaborators from General questioning (d = 1.46). These findings suggest that identifying subgroups is important in developing and evaluating the effectiveness of reading comprehension interventions.  相似文献

In this article we review the literature on attachment patterns in institutionalized children and then perform a meta-analysis on data from 10 attachment studies involving 399 children in institutional settings. We computed the overall attachment distribution of secure, insecure, and disorganized rates and explored the effect of a set of moderating variables (i.e., country of institutionalization, attachment assessment procedure, age at entry, and age at assessment). To overcome bias related to the small number of studies, we conducted both classical and Bayesian meta-analysis and obtained comparable results. Distribution of children's attachment patterns was: 18% secure, 28% insecure, and 54% disorganized/cannot classify. Compared to their family-reared peers, children living in an institution were found to be at greater risk for insecure and disorganized attachment, with a similar medium effect size for both distributions (d = 0.77 and d = 0.76, respectively). The following moderating variables were associated with insecure attachment: representational assessment procedures (d = 0.63) and Eastern European countries of origin (d = 1.13). Moderators for disorganized attachment were: Eastern European countries of origin (d = 1.12), age at institution entry before the first birthday (d = 0.93), and age at assessment under three years of age (d = 0.91). Implications for child development and policies are discussed.  相似文献

The purpose of this study was to identify the extent to which intrinsic student factors such as cognitive learning style, learning strategies, motivation and statistics anxiety, as well as certain demographic factors, predict performance on a research design and analysis course (RDAIIA) in the Department of Psychology at the University of the Witwatersrand, South Africa, with a view to developing future interventions for improving student performance. Using a sample of eighty students, it was established that the factors most predictive of RDA performance were secondary school performance (p < 0.0001) and age (p = 0.0106). Excluding demographic factors, self-efficacy (p < 0.0001), help-seeking (p = 0.0531) and a reflective learning style (p = 0.0071) were also found to be predictive. Performance also differed between students who had completed Mathematics on the higher grade in secondary school and those who had completed standard grade (p = 0.016). These findings present both possible directions and substantial challenges for future performance-intervention strategies.  相似文献

In the present paper a model of self-fulfilling prophecy effects in media-based learning was developed and tested. The central model assumption was that information about an instructional medium's quality affects students' academic achievement depending on the instructional content's relevance to the student. Experiment 1 (N = 100) demonstrated higher achievement in response to positive compared to negative information, but not the predicted moderating effect of content relevance. Using a revised relevance manipulation, Experiment 2 (N = 199) identified the following moderating function of content relevance: Under moderate relevance positive information led to higher achievement, under high relevance negative information resulted in higher achievement. No differences appeared under low relevance. Path analyses revealed students' cognitive effort as significant mediator for these effects.  相似文献

The purpose of this study was to test the hypothesis that quality improvements in early childhood centers experience diminishing returns as the quality of the classroom rises with regards to concurrent socio-emotional outcomes. This hypothesis lies at the core of Scarr's argument that public policy should concentrate on improving low quality settings rather than improving settings that already have acceptable quality. The study detected sizeable effect sizes linking process quality in the good to excellent range with reduction of existing socio-emotional risk factors (d = 0.51) and prevention of the emergence of new socio-emotional risk factors (d = −0.41). These effect sizes are substantially larger than those reported by other studies investigating quality environments in the poor to good quality range (d = 0.16), and larger than Durlak and Wells meta-analytic effect size for universal preventive interventions (d = 0.35). Therefore, the hypothesis that as quality increases the benefits for children increase but at a diminishing rate was rejected for concurrent socio-emotional outcomes in urban populations.  相似文献

The effects of intervention for peer mediation and mother-child mediated learning experience (MLE) strategies on children’s MLE strategies and cognitive modifiability (CM) was investigated on a sample of 100 mother–child dyads. CM was examined in domains of executive functions and analogical reasoning. The MLE interactions were analyzed by Observation for Mediated Interaction (OMI) scale. Children of high- and low-mediating mothers were assigned to experimental (n = 49) and control (n = 51) conditions. The experimental group received a peer-mediation program and the control groups received an alternative creativity program. The children (in Grade 3) were assigned as mediators of learners (in Grade 1) and taught them analogical reasoning problems. The peer interaction was videotaped and analyzed by the OMI. All children were given dynamic assessment after the interaction. Children in the experimental group showed higher MLE strategies and CM than did children in the control condition. Mediators of low-MLE mothers in the experimental group showed greater CM than did mediators in the control group. Structural equation modeling analysis showed that mediators’ cognitive modifiability was explained by proximal factors of treatment, mothers’ quality of mediation (QM) and mediators’ QM; learners’ cognitive modifiability was explained by mediators’ QM. The findings were discussed in relation to the MLE theory and earlier findings.  相似文献

In this study, we investigated the effects of teaching critical-thinking principles on university students’ epistemological beliefs, whether these effects had any relation to the teaching approaches, and whether there was any significant interaction effect between teaching approach and students’ epistemological beliefs. One hundred and eight undergraduates were randomly assigned to three different 65-min instructional interventions, namely, General, Infusion, and Immersion approaches. Statistical analyses of the data using a Repeated Measures ANOVA showed a statistically significant higher post-assessment performance, F (1, 105) = 19.769, p = .00. The main effect related to the intervention was also significant, F (2, 105) = 3.995, p = .021, but there was no significant interaction between intervention and epistemological beliefs. Post hoc comparisons revealed that students assigned to the Infusion strategy outperformed those assigned to the General approach on epistemological change.  相似文献

Two experiments examined visual attention distribution in learning from text and pictures. Participants watched a 16-step multimedia instruction on the formation of lightning. In Experiment 1 (N = 90) the instruction was system-paced (fast, medium, slow pace), while it was self-paced in Experiment 2 (N = 31). In both experiments the text modality was varied (written, spoken). During learning, the participants’ eye movements were recorded. Results from both experiments revealed that learners spent more time studying the visualizations with spoken text than those with written text. In written text conditions learners consistently started reading before alternating between text and visualization; moreover, they spent more time reading the text than inspecting the visualizations. While in Experiment 1 additional time that was made available in conditions with a slow or medium instruction pace was spent inspecting visualizations, in Experiment 2 longer learning times resulted from reading the text more intensively. With respect to learning outcomes (retention, transfer, and visual memory) Experiment 1 revealed an effect of text modality for visual memory only. In Experiment 2 no modality effects were found. Instruction pace was hardly related to learning outcomes. Overall, the results confirm prior findings suggesting that the distribution of visual attention in multimedia learning is largely guided by the text.  相似文献

We studied the connection of IQ, reading disability (RD) and their interaction with reading, spelling and other cognitive skills in adolescents with average IQ and RD (n = 22), average IQ, non-RD (n = 71), below average IQ and RD (n = 29), and below average IQ non-RD (n = 33). IQ was not connected to reading and spelling in subjects without RD, but a connection to non-word spelling in subjects with RD existed. IQ and RD showed a connection to other cognitive skills (IQ to working memory, verbal memory and syntactic skills, RD to poor performance in text reading and rapid naming and both of them to reading comprehension, phonological and arithmetic skills), but no interaction existed. Our results are consistent with those of earlier studies showing that IQ does not play a significant role in the presentation of RD. However, adolescents with below average IQ and RD seemed to have much broader deficits in academically important skills such as arithmetic and reading comprehension than the other groups.  相似文献

Parenting programs in high-income countries have been shown to reduce the risk of child maltreatment. However, there is limited evidence of their effectiveness in low- and middle-income countries. The objective of this study was to examine the initial effects of a parenting program in reducing the risk of child maltreatment in highly-deprived and vulnerable communities in Cape Town, South Africa. Low-income parents (N = 68) with children aged three to eight years were randomly assigned to either a group-based parenting program or a wait-list control group. Observational and parent-report assessments were taken at baseline and at immediate post-test after the intervention was delivered. Primary outcomes were parent-report and observational assessments of harsh parenting, positive parenting, and child behavior problems. Secondary outcomes were parent-report assessments of parental depression, parenting stress, and social support. Results indicated moderate treatment effects for increased frequency of parent-report of positive parenting (d = 0.63) and observational assessments of parent-child play (d = 0.57). Observational assessments also found moderate negative treatment effects for less frequent positive child behavior (d = −0.56). This study is the first randomized controlled trial design to rigorously test the effectiveness of a parenting program on reducing the risk of child maltreatment in sub-Saharan Africa using both observational and self-report assessments. Results provide preliminary evidence of effectiveness of reducing the risk of child maltreatment by improving positive parenting behavior. Further development is required to strengthen program components regarding child behavior management and nonviolent discipline strategies. Future research would benefit from a larger trial with sufficient power to determine program effectiveness.  相似文献

The purpose of this study was to investigate relationships between grade level, perceptual learning style preferences, and language learning strategies among Taiwanese English as a Foreign Language (EFL) students in grades 7 through 9. Three hundred and ninety junior high school students participated in this study. The instruments for data collection were the Perceptual Learning Style Preference Questionnaire (PLSPQ) and the Strategy Inventory for Language Learning (SILL). Results showed that statistically significant relationships were found to exist between grade level and kinesthetic learning style preference (p = .001), tactile learning style preference (p = .047), and individual learning style preference (p = .02). Results also showed that statistically significant relationships were found to exist between grade level and the use of memory strategies (p = .005), cognitive strategies (p = .02), metacognitive strategies (p = .000), affective strategies (p = .000) and social strategies (p = .000). Implications are that it is critical for classroom teachers to be more aware of the differences in their students and ensure that their courses present information that appeal to students in different grade levels.  相似文献

Research on the implementation of reading strategies suggests that self-regulated learning might be a powerful framework to optimize effects on reading comprehension. Models of self-regulation emphasize that the teaching of strategy knowledge (Strat) has to be complemented by offering skills of cognitive (CSR) and motivational (MSR) aspects of self-regulation. In order to investigate whether all aspects of this model have to be carried out under regular classroom conditions, three different strategy programs (Strat + CSR + MSR vs. Strat + CSR vs. Strat) and a control condition were compared. Within a pre-, post-, and retention-test design with 20 classes, comprising of 593 fifth-graders (11 years), development of strategy knowledge, reading comprehension, school-related self-efficacy, and motivational orientation towards learning goals were assessed. While all strategy-oriented programs proved to enhance reading competence, understanding of reading strategies and competence for application of reading strategies, gains in self-efficacy did not differ from the control condition. As regards the retention test, the program that covered all aspects of strategy instruction (MSR + Strat + CSR) showed strongest effects as predicted by self-regulation theory.  相似文献

We present some key findings of a four-year, two-phase writing assessment project at Central Michigan University: Phase One (2002), a survey of faculty members (n = 115) and subsequent focus groups (n = 14) and Phase Two (2005), an evaluation of two samples of student writing (n = 635 and 632). Major findings of Phase One reported here include the amounts and types of writing assigned by faculty members and their perceptions about the quality of their students’ writing. Phase Two revealed some surprising results about our students’ critical reading and writing abilities, confirmed the limitations of a timed-writing assessment methodology, and exposed an intriguing artifact of the data set. We reflect on the process of developing and conducting the assessment project, examine its strengths and weaknesses, and share our thoughts about the next phase of our assessment odyssey.  相似文献

How do concrete objects that cue real-world knowledge affect students' performance on mathematics word problems? In Experiment 1, fourth- and sixth-grade students (N = 229) solved word problems involving money. Students in the experimental condition were given bills and coins to help them solve the problems, and students in the control condition were not. Students in the experimental condition solved fewer problems correctly. Experiment 2 tested whether this effect was due to the perceptually rich nature of the materials. Fifth-grade students (N = 79) were given: perceptually rich bills and coins, bland bills and coins, or no bills and coins. Students in the perceptually rich condition made the most errors; however, their errors were least likely to be conceptual errors. Results suggest that the use of perceptually rich concrete objects conveys both advantages and disadvantages in children's performance in school mathematics.  相似文献

As teachers struggle to meet the needs of a highly diverse student body, technology holds out the promise of a solution. However, first the nature and scope of differences between students has to be identified. This study (n = 1811) takes a comprehensive approach, selecting differences from each stage in the learning process. These were termed learning orientations. Factor analysis (FA) produced ten learning orientations, which were then subjected to a second order FA. Three learning pathways emerged; cognitive voyaging, industrious pragmatism and multimedia collaboration. About 65% of students are high on industrious pragmatism, 15% high on cognitive voyaging and 9.2% multimedia collaboration. Both learning orientations and learning pathways were used in ANOVAS and t-tests to explore differences in age, gender and ethnicity. Students who were younger and/or of Asian or Polynesian ethnicity were more likely to follow a multimedia collaboration pathway. Older students are more likely to go the cognitive voyaging or industrious pragmatism way.  相似文献

This meta-analysis (29 studies, k = 33, N = 4158) examined the longitudinal development of the relationship between performance self-efficacy and transfer before and after training. A specific focus was on training programs that afforded varying degrees of computer-supported collaborative learning (CSCL). Consistent with social cognitive theory, results suggested positive population correlation estimates between self-efficacy and transfer before (ρ = 0.31) and after (ρ = 0.39) training, and thus a small but positive increase. Three boundary conditions were estimated. First, effect sizes were higher in trainings with rather than without computer support. Second, effect sizes were higher in trainings without rather than with collaboration. Third, time lag had marginal effects. These findings are discussed in terms of their implications for theories of complex social and computer-mediated learning environments and their practical significance for scaffolding technology-enhanced learning and interaction.  相似文献

Educational video games are hypothesized to be good environments for promoting learning; however, research on conceptual learning from games is mixed. We tested whether embedding a learning support in the form of short animations illustrating physics concepts that can be used to aid gameplay improved learning. Ninety-six 7th to 11th grade students were randomly assigned to play Physics Playground with or without the learning supports over a 4-day period. Results indicate that students who played a version of the game with embedded learning supports showed more improvement on a far- (d = 0.36), but not on a near-transfer physics assessment (d = 0.17) compared to those who played without the supports. The learning supports did not affect students’ enjoyment with the game. We conclude that the game-embedded animations were effective at promoting conceptual learning without sacrificing the fun of game-based learning.  相似文献
