Although many children with reading difficulty (RD) are reported to struggle with mathematics, little research has empirically investigated whether this is the case for different types of RD. This study examined the mathematics skills of third graders with one of two types of RD: dyslexia (n = 18) or specific reading comprehension difficulty (n = 22), as contrasted to a comparison group (n = 247). Children's performance on arithmetic fact fluency, operations, and applied problems was assessed using standardized measures. The results indicated that children with dyslexia experienced particular difficulty with arithmetic fact fluency and operations: they were 5.60 times and 8.54 times more likely than other children to experience deficits in fact fluency and operations, respectively. Our findings related to arithmetic fact fluency were more consistent with domain-general explanations of the co-morbidity between RD and mathematics difficulty, whereas our findings related to operations were more consistent with domain-specific accounts.  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

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

In Singapore, 6–12 year-old students are taught to solve algebra word problems with a mix of arithmetic and pre-algebraic strategies; 13–17 year-olds are typically encouraged to replace these strategies with letter-symbolic algebra. We examined whether algebra problem-solving proficiency amongst beginning learners of letter-symbolic algebra is correlated with the ability to inhibit intrusions from the earlier arithmetic strategies. Similar to typical school practice in Singapore, we asked 14 year-old students (N = 157) to use only letter-symbolic algebra to solve 9 algebra word problems. After having controlled for algebraic knowledge, working memory, and intelligence, better inhibitory ability still predicted fewer arithmetic intrusions and higher problem solving accuracy. Path analysis revealed 2 types of inhibition. Inhibition-of-reified-processes predicted accuracy through arithmetic intrusions. Inhibition-of-recently-learned-associations predicted accuracy through intelligence. Findings suggest establishing pedagogical links between arithmetic and algebraic methods may facilitate students' transition to letter-symbolic algebra.  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

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

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

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

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

Recent models of attention deficit/hyperactivity disorder (ADHD) suggest that the association between achievement motivation and school performance may be stronger in children with ADHD than in typically developing children. Therefore, the present study investigated associations between achievement motivation and performance on language skills and mathematical thinking in children with ADHD (n = 23; M = 9.4 years, SD = 1.1 years; 78% boys) and two matched control groups, i.e., a clinical control group (children with related disruptive behavior disorders; DBD), and a non-clinical control group (NC). Results confirmed stronger associations between achievement motivation and performance on receptive language and mathematical thinking in children with ADHD than in NC. Specifically, performance of children with ADHD was equal to NC for highly motivated ADHD children. These results underscore the importance of achievement motivation as a more essential key factor in the performance of children with ADHD as compared to typically developing children.  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

The relations between students' value orientations and experiences of motivational interference during studying following conflicts between learning and leisure activities were investigated in a self-report study. Overall, 1075 adolescents, mostly from Catholic schools, in Bosnia–Herzegovina (n = 203), India (n = 200), Paraguay (n = 96), Spain (n = 442), and the US (n = 134), participated. The samples varied substantially in terms of modern and postmodern value orientations, experience of motivational interference during studying, and time invested in studying. By controlling for age, gender, and economic capital, postmodern value orientation was positively related to conflict frequency and experience of motivational interference during learning, and negatively related to time investment. For modern value orientation, the relations were almost reversed. Despite the considerable differences between the sample means, the study revealed some consistency in the relations between the variables across the samples, which indicates that most of the relations can be generalized.  相似文献

This study modified and validated a measure of motivational orientations – grounded in self-determination theory and originally developed for postsecondary students – for use with younger (pre-college) English language learners (ELLs). Exploratory factor analysis results in Sample A (n = 528) indicated that the data were best explained by a three-factor solution (intrinsic motivation, introjected regulation, and external regulation) that explained 51.6% of the variance. These results were corroborated by a confirmatory factor analysis in an independent Sample B (n = 529; GFI = .97, CFI = .96, SRMR = .04, RMSEA = .05). The test for invariance across the two samples further supported the validity of the measure. The modified instrument, named English Language Learner Motivation Scale (ELLMS): Pre-College, showed strong psychometric characteristics for use with elementary (ages 9–11 years), middle (ages 12–14 years), and high school (ages 16–17) ELLs. Applications of the measure are discussed.  相似文献

Prevention programs often encourage sexually abused children to disclose without fully considering the potential for adverse consequences. This study examined the impact of disclosure on abuse cessation and later adult symptomatology. A clinical sample of 301 adult survivors completed the Impact of Event Scale (IES/IES-R), and the Beck Depression Inventory (BDI-II). Participants were divided into 3 groups: Nondisclosure (n = 221), Disclosure/Abuse Ended (n = 25), and Disclosure/Abuse Continued (n = 55). Multivariate analyses of covariance, adjusting for abuse characteristics (age of onset, penetration, and number of perpetrators) and other trauma exposure, revealed significant differences in psychiatric symptom severity among the three groups, Wilks’ λ = 0. 95, F (6, 584) = 2.69, p = 0.014, ηp2 = 0.03. Specifically, those in the Disclosure/Abuse Continued group scored significantly higher on the IES/IES-R Intrusion subscale (p = 0.04) and the BDI-II (p = 0.01), as compared to the Nondisclosure group. The Disclosure/Abuse Ended group did not differ significantly from the other groups. Results suggest that disclosure may be detrimental unless adequate steps are taken to ensure abuse cessation and appropriate treatment.  相似文献

Prevalence of Internet use among adolescents is high, but little is known about the online sexual activities of German adolescents. This study aimed to describe the 12-month prevalence of German adolescents’ online sexual experiences with a focus on Online Sexual Solicitation (OSS, subjectively negative online sexual experiences with a peer or any sexual online experience, positive or negative, with an adult). A sample of male and female adolescents aged 14–17 (N = 2238) was recruited using online survey panel. The sample was representative for gender and education. Subjects completed an online survey reporting their online sexual activities (i.e., sexual conversation, exchanging pictures, and cybersex) with peers (14–17 y.) and/or adults (≥18 y.). Findings illustrated that 51.3% (n = 1148) of adolescents had experienced online sexual activity, which mostly involved peers (n = 969; 84.4%). In contrast, 23.2% (n = 519) of the adolescents experienced OSS with 2.6% (n = 57) reporting subjectively negative online sexual interactions with peers and 22.2% (n = 490) reporting online sexual interactions with adults, of which 10.4% (n = 51) were perceived as negative. The findings suggest that adolescents frequently engage in sexual interactions on the Internet with only a relatively small number perceiving such contacts as exploitative. In addition, females and adolescents with incomplete family situation, foreign nationality, higher education, homo- or bisexual orientation, and those without perceived social support reported OSS significantly more often.  相似文献

Australia needs effective programs to protect children and prevent abuse, but there is little information available for policymakers or families. Using a randomized controlled trial, Learn to BE SAFE with Emmy™, a school-based protection program for young children designed by Act for Kids, was evaluated to determine its effectiveness for promoting young children's knowledge and skills. Grade one children (n = 245) from 15 classrooms across 5 primary schools completed assessment measures. A subset of these children received the program (n = 131) or acted as a comparison group (n = 114). Parents (n = 72) completed questionnaires about their child's participation in the program. When compared with children who had not received the program, children who completed Learn to BE SAFE with Emmy™ demonstrated increased knowledge of interpersonal safety and were more likely to choose a safe response option to hypothetical unsafe scenarios 6 months after participation than at both pre- and post-intervention. Parents reported their children who participated used more safety strategies immediately and 6 months after participation compared to pre-intervention. Outcomes can assist in guiding future policies around the prevention of child abuse and protect the well-being of Australian children.  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

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

ObjectiveThe sexually abused–sexual abuser hypothesis states there is a specific relationship between sexual abuse history and sexual offending, such that individuals who experience sexual abuse are significantly more likely to later engage in sexual offenses. Therefore, samples of adult sex offenders should contain a disproportionate number of individuals who have experienced sexual abuse, but not necessarily other types of abuse, compared with samples of other types of offenders.MethodsWe compared rates of sexual and other forms of abuse reported in 17 studies, involving 1,037 sex offenders and 1,762 non-sex offenders. We also examined the prevalence of different forms of abuse in 15 studies that compared adult sex offenders against adults (n = 962) and against children (n = 1,334), to determine if the sexually abused–sexual abuser association is even more specific to individuals who sexually offend against children.ResultsWe observed a higher prevalence of sexual abuse history among adult sex offenders than among non-sex offenders (Odds Ratio = 3.36, 95% confidence intervals of 2.23–4.82). The two groups did not significantly differ with regard to physical abuse history (OR = 1.50, 95% CI = 0.88–2.56). There was a significantly lower prevalence of sexual abuse history among sex offenders against adults compared to sex offenders against children (OR = 0.51, 95% CI = 0.35–0.74), whereas the opposite was found for physical abuse (OR = 1.43, 95% CI = 1.02–2.02).ConclusionThere is support for the sexually abused–sexual abuser hypothesis, in that sex offenders are more likely to have been sexually abused than non-sex offenders, but not more likely to have been physically abused. We discuss potential mechanisms for the relationship between sexual abuse history and sexual offending, including the possibility that a third factor might account for the relationship.Practice implicationsThe most obvious implications of these findings is that the prevention of sexual abuse of children, either through prevention programs directly targeting children or through treatment programs targeting individuals who are likely to sexually offend against children (e.g., known sex offenders against extra-familial boys), may eventually reduce the number of sex offenders. This implication is dependent, however, on a causal role of childhood sexual abuse, and on the effectiveness of prevention and treatment practices.  相似文献

Many children involved with the child welfare system witness parental domestic violence. The association between children's domestic violence exposure and child welfare involvement may be influenced by certain socio-cultural factors; however, minimal research has examined this relationship. The current study compares domestic violence experiences and case outcomes among Latinas who are legal immigrants (n = 39), unauthorized immigrants (n = 77), naturalized citizens (n = 30), and US-born citizen mothers (n = 383) reported for child maltreatment. This analysis used data from the second round of the National Survey of Child and Adolescent Well-being. Mothers were asked about whether they experienced domestic violence during the past year. In addition, data were collected to assess if (a) domestic violence was the primary abuse type reported and, if so, (b) the maltreatment allegation was substantiated. Results show that naturalized citizens, legal residents, and unauthorized immigrants did not differ from US-born citizens in self-reports of domestic violence; approximately 33% of mothers reported experiences of domestic violence within the past year. Yet, unauthorized immigrants were 3.76 times more likely than US-born citizens to have cases with allegations of domestic violence as the primary abuse type. Despite higher rates of alleged domestic violence, unauthorized citizens were not more likely than US-born citizens to have these cases substantiated for domestic violence (F(2.26, 153.99) = 0.709, p = .510). Findings highlight that domestic violence is not accurately accounted for in families with unauthorized immigrant mothers. We recommend child welfare workers are trained to properly assess and fulfill the needs of immigrant families, particularly as it relates to domestic violence.  相似文献
