Arithmetic word problems are often presented accompanied by illustrations. The present study examined how different types of illustrations influence the speed and accuracy of performance of both good (n = 67) and poor arithmeticians (n = 63). Twenty-four arithmetic word problems were presented with four types of illustrations with increasing information value. The results show that illustrations can have a detrimental effect on performance on arithmetic word problems, produced by irrelevant, redundant or interacting sources of information. Principles from cognitive load theory are used to explain the results, in particular in relation to (poor) working memory ability. 相似文献

Maltreated children show poor emotion regulation competencies compared to non-maltreated children. Emotion regulation has been found to mediate the association between maltreatment and behavior problems in children. The aim of the present study was to examine the relationships among child sexual abuse (CSA), emotion regulation (ER), and internalized and externalized behavior problems in preschoolers using conditional process analyses. ER competencies were assessed in 127 children aged 41–79 months (62 abused, 65 non-abused) by their parents (N = 124) and early childhood educators (N = 88) using the Emotion Regulation Checklist (Shields and Cicchetti, 1995, Shields and Cicchetti, 1997). Behavior problems were evaluated by parents using the Child Behavior Checklist (Achenbach and Rescorla, 2000, Achenbach and Rescorla, 2001). ER was found to completely mediate the relation between CSA and internalized behavior problems and partially mediate the relation between CSA and externalized behavior problems. Parents’ and educators’ evaluations of ER were also found to differ as a function of child gender. The discussion focuses on the relationships among CSA, ER, behavior problems, and child gender. The clinical implications of these findings are also examined. Promoting the optimal development of ER could prevent the emergence and exacerbation of behavior problems in these at-risk children and, in turn, foster resilience. 相似文献

This study investigated factors promoting the use of self-constructed diagrams by examining students' perceptions and daily class activities, and comparing Japanese (n = 291) and New Zealand (n = 323) students. Algebra word problems and a questionnaire were administered. The results revealed that the New Zealand students used diagrams more often and scored higher than their Japanese counterparts. Lack of confidence and perceptions of difficulty in diagram use, and viewing diagrams more as a strategy that teachers use, were found to link with lower use. Possible ways of promoting diagram use in math word problem solving are discussed. 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

The ability of school children (N = 233) to acquire new scientific vocabulary was examined. Children from two age groups (M = 4.8 and M = 6.5) were introduced to previously unknown words in an educational video. Word knowledge was assessed through accuracy and latency for production and comprehension over a 9-month period. A draw and write task assessed acquisition of domain knowledge. Word learning was poorer than has previously been reported in the literature, and subject to influences of word type (domain specificity) and word class. The results indicate that the acquisition of scientific terms is a complex process moderated by lexical, semantic and pragmatic factors. 相似文献

Within a democratic and multicultural society, diversity is a reality, and differences between students are a fact which teachers have to deal with on a daily basis. Differentiated instruction aims to meet these differences in learning in order to provide all students with the best possible learning opportunities. However, to date no validated instruments exist to measure teachers’ perceptions of differentiated instruction and their related classroom practices. This study, therefore, examined the factor structure and reliability of the Differentiated Instruction Questionnaire, called the DI-Quest instrument. A list of 87 items was constructed, building on existing prevalent theoretical models of Differentiated Instruction (e.g. Tomlinson, 2014; Hall, 2002). An exploratory and confirmatory factor analysis was undertaken to investigate the factor structure of the questionnaire. As a result, five factors emerged: two factors related to the teachers’ philosophy of differentiated instruction (the teachers’ mindset and their ethical compass), two factors referred to the practical principles that teachers apply to differentiate (flexible grouping and output = input) and the last factor (differentiated instruction) covered the self-reported extent to which teachers differentiated their instruction related to three types of differences in learning (students’ interests, readiness and learning profile). As a result, the DI-Quest instrument entailed 31 items with a five-factor structure indicating a good fit (CFI = 0.919; TLI = 0.911; RMSEA = 0.041 [0.037–0.044 – 90% confidence interval, p(0.05) = 1.000]; SRMR = 0.048; χ2 = 5888.338, df = 465, p = 0.000). In addition, assuming theoretical relatedness between the factors, the validation of a DI-Quest model was empirically validated. We compared the model fit for two models by investigating which model had a lower BIC and AIC value and by comparing their chi square values. The best-fitting DI-Quest model showed four factors (teachers’ mindset, ethical compass, flexible grouping and output = input as dependent variables) functioning as significant predictors of the fifth factor (the self-reported adoption of Differentiated Instruction, which served as an independent variable). Moreover, this paper also discusses the psychometric properties of the DI-Quest instrument and the implications of the model for schools, educators and researchers. 相似文献

The aim of this study was to analyze the effect of poly-victimization on symptom severity among adolescents being cared for by the child welfare system in a southwestern European country. The sample consisted of 127 youths (62 males and 65 females) aged 12–17 years (M = 14.60, SD = 1.61) who were recruited from short- and long-term residential centers. The Juvenile Victimization Questionnaire (Finkelhor, Hamby, Ormrod, & Turner, 2005) and the Youth Self-Report (Achenbach & Rescorla, 2001) were used to assess interpersonal victimization experiences and psychopathology, respectively. Victim (n = 68), low poly-victim (n = 48), and high poly-victim (n = 18) groups had comparable rates of psychopathology severity, with the exception of rule-breaking behavior, which was more severe among those with more victimization experiences (Cramer's V = .342). Poly-victimization was shown to be a significant predictor of clinically severe rule-breaking behavior, thought problems, and anxiety/depression symptoms. Among victimization types, sexual and electronic victimization significantly predicted withdrawn/depressed and aggressive behavior, and attention problems, respectively. The results of this study highlight the importance of assessing a wide range of victimization experiences among adolescents in care, since poly-victimization seems to underlie the serious psychological problems these youth present. 相似文献

Adverse Childhood Experiences (ACEs) such as child abuse are related to poor health outcomes. Spanking has indicated a similar association with health outcomes, but to date has not been considered an ACE. Physical and emotional abuse have been shown in previous research to correlate highly and may be similar in nature to spanking. To determine if spanking should be considered an ACE, this study aimed to examine 1): the grouping of spanking with physical and emotional abuse; and 2) if spanking has similar associations with poor adult health problems and accounts for additional model variance. Adult mental health problems included depressive affect, suicide attempts, moderate to heavy drinking, and street drug use. Data were from the CDC-Kaiser ACE study (N = 8316, response rate = 65%). Spanking loaded on the same factor as the physical and emotional abuse items. Additionally, spanking was associated with increased odds of suicide attempts (Adjusted Odds Ratios (AOR) = 1.37; 95% CI = 1.02 to1.86), moderate to heavy drinking (AOR) = 1.23; 95% CI = 1.07 to 1.41), and the use of street drugs (AOR) = 1.32; 95% CI = 1.4 to 1.52) in adulthood over and above experiencing physical and emotional abuse. This indicates spanking accounts for additional model variance and improves our understanding of these outcomes. Thus, spanking is empirically similar to physical and emotional abuse and including spanking with abuse adds to our understanding of these mental health problems. Spanking should also be considered an ACE and addressed in efforts to prevent violence. 相似文献

The present study extends prior research examining the association between borderline personality disorder (BPD) features and child physical abuse (CPA) risk. We hypothesized that: (1) high CPA risk parents (compared to low CPA risk parents) would more often report clinically elevated levels of BPD features; (2) high CPA risk parents with elevated BPD features would represent a particularly high-risk subgroup; and (3) the association between elevated BPD features and CPA risk would be partially explained by emotion regulation difficulties. General population parents (N = 106; 41.5% fathers) completed self-report measures of BPD features, CPA risk, and emotion regulation difficulties. Results support the prediction that BPD features are more prevalent among high (compared to low) CPA risk parents. Among the parents classified as high CPA risk (n = 45), one out of three (33.3%) had elevated BPD features. In contrast, none of the 61 low CPA risk parents reported elevated BPD symptoms. Moreover, 100% of the parents with elevated BPD features (n = 15) were classified as high-risk for CPA. As expected, high CPA risk parents with elevated BPD features (compared to high CPA risk parents with low BPD features) obtained significantly higher scores on several Child Abuse Potential Inventory scales, including the overall abuse scale (d = 1.03). As predicted, emotion regulation difficulties partially explained the association between BPD features and CPA risk. Findings from the present study suggest that a subset of high CPA risk parents in the general population possess clinically significant levels of BPD symptoms and these parents represent an especially high-risk subgroup. Interventions designed to address BPD symptoms, including emotion regulation difficulties, appear to be warranted in these cases. 相似文献

A cognitive lab technique (n = 156) was used to investigate interactions between individual factors and item factors presumed to affect assessment validity for diverse students, including English language learners. Findings support the concept of access — an interaction between specific construct-irrelevant item features and individual characteristics that either permits or inhibits student response to the targeted measurement content of an assessment item. Access issues of 3rd and 5th grade students were explored at three stages during problem solving on mathematics items: 1) apprehension of task demands; 2) formulation of a solution; and 3) articulation of a solution. Adequacy of access at these levels appears to affect student performance. In particular, where students were able to experience increased apprehension in the first stage through the provision of item variations consistent with their individual access needs, they were more likely to formulate correct solution strategies. The implications of these findings are discussed and suggestions for future research are offered. 相似文献

Attachment disorders, specifically Reactive Attachment Disorder (RAD) and Disinhibited Social Engagement Disorder (DSED) are disorders associated with neglect and abuse in which people have significant difficulties relating to others. This study aims to explore Attachment Disorder symptoms and diagnoses in young offenders and factors that may be associated with them such as mental health problems. A cross-sectional design was used with 29 young people who were known to Intensive Services, aged 12–17 (M = 16.2, SD = 1.3), 29 carers and 20 teachers. They completed measures investigating symptoms of Attachment Disorders and psychopathology. Eighty-six percent of the young people had experienced some form of maltreatment and the rates of an actual or borderline Attachment Disorder was 52%. A positive correlation between Attachment Disorder symptoms and other mental health problems (as rated by carer-report Strengths and Difficulties Questionnaire Total Difficulties Score), accounting for 36% of the variance was found, with a large effect size (rs = 0.60). Attachment Disorder symptoms were associated with hyperactivity and peer relationship problems. 相似文献

The goal of this study was to examine the influence of animal-assisted psychotherapy (AAP) on the psychosocial adaptation of a group of adolescents in residential care who had suffered traumatic childhood experiences and who presented with mental health problems. This study recruited 63 youths (mean age = 15.27, SD = 1.63) who were divided into two groups: a treatment group of 39 youths (19 female and 20 male; mean age = 15.03, SD = 0.51) and a control group of 24 (five female and 19 male; mean age = 15.67, SD = 1.63). The youths who underwent the AAP program had higher school adjustment in comparison to their peers who did not receive treatment. Their hyperactive behavior decreased, and they showed better social skills, more leadership, and fewer attention problems. They also showed a more positive attitude toward their teachers in comparison to controls. No differences were observed in other variables associated with clinical symptoms or personal adjustment. These results suggest that AAP can be effective with teenagers who have suffered childhood traumas and who present with problems of psychosocial adaptation. 相似文献

History of child abuse is considered one of the important risk factors of suicide attempt in general population. At the same time it has been shown that suicide attempts appear significantly more frequently in alcoholics than in healthy individuals. The objective of this study was to investigate associations between history of childhood sexual abuse and suicide attempts in a sample of Polish alcohol dependent patients. A sample of 364 alcohol-dependent subjects was recruited in alcohol treatment centers in Warsaw, Poland. Information was obtained about demographics, family history of psychiatric problems, history of suicide attempts, sexual and physical abuse during childhood and adulthood and severity of alcohol problems. When analyzed by gender, 7.4% of male and 39.2% of female patients had a lifetime history of sexual abuse; 31.9% of the study group reported at least one suicide attempt during their lifetime. Patients who reported suicide attempts were significantly younger (p = 0.0008), had greater severity of alcohol dependence (p = 0.0002), lower social support (p = 0.003), and worse economic status (p = 0.002). Moreover, there was a significant association between history of suicide attempts and family history of psychiatric problems (p = 0.00025), suicide attempts in the family (p = 0.0073), childhood history of sexual abuse (p = 0.009) as well as childhood history of physical abuse (p = 0.002). When entered into linear regression analysis with other dependent variables history of childhood sexual abuse remained a significant predictor of suicide attempt (OR = 2.52; p = 0.035). Lifetime experience of sexual abuse is a significant and independent risk factor of suicide attempts in alcohol-dependent individuals. 相似文献

This study aimed at modeling individual and average non-linear trajectories of positional learning using a structured latent growth curve approach. The model is based on an exponential function which encompasses three parameters: Initial performance, learning rate, and asymptotic performance. These learning parameters were compared in a positional learning task administered to a sample comprising the whole adult lifespan (N = 527; age range: 20 years to 89.3 years; Mage = 52.95, SDage = 17.37). Additionally, three explanatory variables, age, speed of information processing, and educational level were included in the analyses. All three learning parameters showed reliable individual differences. The correlations between the learning parameters indicated that those participants with high learning rates needed more trials to achieve their asymptotic performance and those who recalled more items initially also had a higher asymptotic performance. Older persons showed lower initial performance and lower asymptotic performance, whereas speed of information processing was positively associated only with initial performance. Persons with more years of formal education had a higher initial performance and a higher asymptotic performance. The learning rate, in turn, appeared to be unaffected by all three predictor variables. 相似文献

The relation between 2 forms of mathematical cognition, calculations and word problems, was examined. Across grades 2–3, performance of 328 children (mean starting age 7.63 [SD = 0.43]) was assessed 3 times. Comparison of a priori latent change score models indicated a dual change model, with consistently positive but slowing growth, described development in each domain better than a constant or proportional change model. The bivariate model including change models for both calculations and word problems indicated prior calculation performance and change were not predictors of subsequent word-problem change, and prior word-problem performance and change were not predictors of subsequent calculation change. Results were comparable for boys versus girls. The bivariate model, along with correlations among intercepts and slopes, suggest calculation and word-problem development are related, but through an external set of overlapping factors. Exploratory supplemental analyses corroborate findings and provide direction for future study. 相似文献

This study investigated whether children's inversion shortcut use (i.e., reasoning that no calculations are required for the problem 4 × 8 ÷ 8, as the answer is the first number) is related to their analogical reasoning ability, short-term memory capacity, and working memory capacity. Children from Grades 6 and 8 solved multiplication and division inversion problems and classical analogy word problems and completed memory tasks. Analogical reasoning ability and working memory functioning both accounted for individual variance in inversion shortcut use. These findings suggest that the ability to understand relationships and executive functioning may enable children to internally represent and manipulate mathematical problems, facilitating the application of conceptual mathematical knowledge to generate the inversion shortcut. 相似文献

This study examined differences in offending behavior and psychosocial problems between juvenile offenders who have been sexually abused (n = 231), physically abused (n = 1,568), neglected (n = 1,555), exposed to multiple forms of maltreatment (n = 1,767), and non-victims (n = 8,492). In addition, the moderating effect of gender in the association between type of maltreatment and offending behavior/psychosocial problems was examined. Results showed that violent offenses were more common in victims of physical abuse and victims of multiple forms of abuse than in non-victims, both in boys and girls. In boys, sexual offenses were far more common in victims of sexual abuse than in victims of other or multiple forms of maltreatment or in non-victims. In girls, no group differences were found in sexual offending behavior. For both boys and girls, externalizing problems were relatively common in victims of physical abuse and neglect whereas internalizing problems were relatively common in victims of sexual abuse. In victims of multiple forms of maltreatment, both internalizing and externalizing problems were relatively common. Implications for clinical practice are discussed. 相似文献

In this study, we investigated the expressive language development of 186 18–35 months old Chinese girls adopted into American families. The adoptees were adopted between 3 and 25 months (M = 11.0, S.D. = 3.1) and had lived in the adoptive families for 3–27 months (M = 16.2, S.D. = 5.8) at the time of the study. The adoptive mothers provided information on the adoptees’ pre- and post-adoption experiences, behavioral-emotional problems, and spontaneously uttered words and phrases. Cross-sectional data indicated that the adoptees experienced a full catch up after living in the adoptive families for an average of about 16 months. After that, the adoptees’ language level surpassed the U.S. norms for the same age group. Findings also suggested that the adoptees’ current age and age at adoption were associated with vocabulary size, while only age at adoption was a significant predictor of average phrase length. Pre-adoption experiences and current family demographics were not associated with the adoptees’ vocabulary size or average phrase length. The adoptees’ externalizing problems were negatively and weakly correlated with their phrase length. 相似文献

This study assessed the relationship between parental punishment and depression as well as quality of life in children with primary monosymptomatic nocturnal enuresis (PMNE). A consecutive sample of 65 children (7–13 years) with PMNE and 40 healthy children, selected as controls (Group III), were included in the study. The children with PMNE were further sub-classified into two groups: Group I, which included children who received parental punishment for enuresis and Group II, which comprised children who were not punished for bedwetting. Depression and health-related quality of life (HRQL) were assessed among the three groups. The number of wet nights per week was significantly increased in Group I compared with Group II (P < .001). In addition, the severity of depressive symptoms increased in Group I as compared to the other two groups (P < .001). Similarly, the psychosocial HRQL lower in Group compared to the control group (Group III) (P < .001). Prior parental discipline, including corporal punishment (B = 0.55, P = .008), as well as the frequency (B = 0.73, P < .001) and duration of punishment (B = 0.33, P = .02) were strong predictors of increased depressive symptom severity. It was also found that prior punishment (B = −0.42, P = .01) and the frequency (B = −0.62, P < .001) and duration of punishment (B = −0.34, P = .02) were strong predictors for poor psychosocial HRQL. Overall, parental punishment has a poor outcome in children with PMNE. 相似文献

Adding representational pictures (RPs) to text-based items has been shown to improve students’ test performance. Focusing on potential explanations for this multimedia effect in testing, we propose two functions of RPs in testing, namely, (1) a cognitive facilitation function and (2) a motivational function. We found empirical support for both functions in this computer-based classroom experiment with N = 410 fifth and sixth graders. All students answered 36 manipulated science items that either contained (text-picture) or did not contain (text-only) an RP that visualized the text information in the item stem. Each student worked on both item types, following a rotated within-subject design. We measured students’ (a) solution success, (b) time on task (TOT), and identified (c) rapid-guessing behavior (RGB). We used generalized and linear mixed-effects models to investigate RPs’ impact on these outcome parameters and considered students’ level of test engagement and item positions as covariates. The results indicate that (1) RPs improved all students’ performance across item positions in a comparable manner (multimedia effect in testing). (2) RPs have the potential to accelerate item processing (cognitive facilitation function). (3) The presence of RPs reduced students’ RGB rates to a meaningful extent (motivational function). Overall, our data indicate that RPs may promote more reliable test scores, supporting a more valid interpretation of students’ achievement levels. 相似文献
