Father absence, perceived, maternal behavior, and moral development in boys.

The rated and observed moral behavior, judgment, and affect of 120 preadolescent, predominantly lower-class boys from early-divorced (before the boys were 6), late-divorced (between 6 and 10), and parentally intact homes were investigated. In addition, the mothers' discipline (power assertive, inductive, and love withdrawal) and affection were examined by asking subjects about their mothers' methods of dealing with their transgressions. Moral behavior was assessed with resistance-to-temptation, self-criticism, altruism, reparation, and teacher-rating measures, while moral judgment was evaluated with 3 Kohlberg items and moral affect was investigated with 2 story-completion items maximizing guilt. The major findings were: (1) when relevant variables (IQ, SES, age, sibling status) were controlled, few differences were found between father-absent and father-present boys; (2) however, father-absent boys were reported by their teachers as less advanced in moral development than father-present boys; (3) the sons of the divorced women showed more "social deviation", according to their teachers, but were more advanced in level of moral judgment than were the sons of widows; (4) divorced women disciplined with more power assertion than widows, according to their sons' reports.     

Does Father Absence Influence Children's Gender Development? Findings From a General Population Study of Preschool Children

Objective. This study aimed to investigate whether preschool children in father-absent families are less gender-typed than their counterparts from father-present homes. Design. Samples of 283 single-mother families, including a subsample of 136 families where the child had no contact with the father, and 6,420 nuclear families were obtained from a longitudinal population study of 14,000 mothers and their children. Gender-role behavior was assessed when the child was 42 months old using the Pre-School Activities Inventory, a reliable and valid instrument designed to discriminate within as well as between the sexes. Results. No difference in parent-reported gender-role behavior was found between father-present and father-absent families for either boys or girls. Conclusions. The findings suggest that the gender-role behavior of preschool children develops typically despite the absence of a live-in father figure.     

A meta-analysis of the relationship of child sexual abuse to HIV risk behavior among women

OBJECTIVE: This study is a meta-analysis of the literature exploring the relationship between child sexual abuse (CSA) and HIV risk behavior among women. Four outcome variables were tested: unprotected sex; sex with multiple partners; sex trading; and adult sexual revictimization. METHOD: Forty-six studies met the inclusion criteria and were included in the analysis, and separate meta-analyses were performed for each of the four dependent variables described above. RESULTS: Using the correlation coefficient r as an effect size estimate, results indicate an average effect size of .05 for the unprotected sex meta-analysis (N = 16 studies), .13 for the sex with multiple partners meta-analysis (N = 23 studies), .12 for the sex trading meta-analysis (N = 23 studies), and .17 for the adult sexual revictimization meta-analysis (N = 21 studies). We conducted a test of three potential moderator variables (source of sample, definition of CSA based on type of contact, and definition of CSA based on maximum age of victim). Results did not support the hypothesis that these three variables explain a significant amount of variability in effect sizes with one exception: Studies that define CSA more broadly to include adolescent victims (e.g., victims up to 17 years of age) had larger and more homogenous effect sizes for the sex trading meta-analysis than those that defined CSA as having occurred at younger ages. CONCLUSIONS: These findings suggest a small positive relationship between CSA and subsequent HIV risk behavior among women that varies as a function of how CSA and HIV risk behavior are operationalized.     

The effectiveness of intelligent tutoring systems on K-12 students' reading comprehension: A meta-analysis

This meta-analysis examined the effectiveness of improving reading comprehension for students in K-12 classrooms using intelligent tutoring systems (ITSs), a computer-based learning environment that provides customizable and immediate feedback to the learner. Nineteen studies from 13 publications incorporating approximately 10 000 students were included in the final analysis; using robust variance estimation to account for statistical dependencies, the 19 studies yielded 88 effect size estimates. The meta-analysis indicated that the overall random effect size of ITSs on reading comprehension was 0.60 (using a mix of standardized and researcher-designed measures) with a 95% confidence interval 0.36 to 0.85 (p < 0.001). This review confirms previous studies comparing ITSs to human tutoring: ITSs produced a small effect size when compared to human tutoring (0.20, 0.02–0.38, p = 0.036, n = 21). All comparisons to human tutoring used standardized measures. This review also found that ITSs produced a larger effect size on reading comprehension when compared to traditional instruction (0.86) for mixed measures and (0.26) for standardized measures. These findings may be of interest to practitioners and policy makers seeking to improve reading comprehension using consistent and accessible ITSs. Recommendations for researchers include conducting studies to understand the difference between traditional and updated versions of ITSs and employing valid and reliable standardized tests and researcher-designed measures.     

Reading research for students with LD: a meta-analysis of intervention outcomes

The present article provides a meta-analysis of instructional research with samples of children and adolescents with learning disabilities in the domains of word recognition and reading comprehension. The results of the synthesis showed that a prototypical intervention study has an effect size (ES) of .59 for word recognition and .72 for reading comprehension. Four important findings emerged from the synthesis: (a) Effect sizes for measures of comprehension were higher when studies included derivatives of both cognitive and direct instruction, whereas effect sizes were higher for word recognition when studies included direct instruction; (b) effect sizes related to reading comprehension were more susceptible to methodological variation than studies of word recognition; (c) the magnitude of ES for word recognition studies was significantly related to samples defined by cutoff scores (IQ > 85 and reading < 25th percentile), whereas the magnitude of ES for reading comprehension studies was sensitive to discrepancies between IQ and reading when compared to competing definitional criteria; and (d) instructional components related to word segmentation did not enter significantly into a weighted least square hierarchical regression analysis for predicting ES estimates of word recognition beyond an instructional core model, whereas small-group interactive instruction and strategy cuing contributed significant variance beyond a core model to ES estimates of reading comprehension. Implications related to definition and instructional components that optimize the magnitude of outcomes are discussed.     

Students’ characteristics and teacher–child relationships in instruction: A meta-analysis

This article suggests that students’ characteristics play a more important role in classrooms than has previously been thought. To investigate this, a computerized literacy search was conducted, finding 19 studies that focused on the topic. On the basis of these studies a meta-analysis was carried out in which 23 effect size estimates were computed. The results showed that teachers reported more conflict and child dependency, and less closeness in teacher–child relationships when interacting with students who exhibited either a high level of external or a high level of internal problem behavior. In contrast, teachers reported less conflict and more closeness in teacher–child relationships when interacting with students exhibiting high levels of motivation and engagement as compared to other children. Furthermore, teachers reported less conflict, less child dependency and more closeness in teacher–child relationships when interacting with students showing a high level of academic performance.     

Girls’ Groups as a Component of Anti‐sexist Practice—one primary school's experience

The gender project I have been involved in was a practical response to theoretical concerns regarding the impact of the hidden curriculum and sex stereotyping in primary schools. The aim of the project was primarily to improve the level of achievement of the girls. Equally important was a desire to broaden curriculum experience into non‐stereotypical areas for both boys and girls. Unlike similar projects, Preston School's single sex groups were monitored throughout their duration. Consequently there are substantially more data on the attitudes of teachers, girls and boys towards gender than are normally available for such projects. This article constitutes an attempt by one of the teachers involved to evaluate the efficacy of Preston School's initiative within a theoretical framework that explores the wider issues of gendered subjectivity, male sexism and female self‐depreciation.     

A meta-analysis of the effects of various science teaching strategies on achievement

This study is a meta-analysis of the question “What are the effects on achievement of different teaching techniques?” Twelve categories of teaching techniques were specified. Among these are questioning, wait-time, testing, focusing, manipulative, presentation approach, inquiry or discovery, audio-visual, and teacher direction. A coding form was then developed to allow for the uniform examination and recording of 76 variables from each study. One or more effect sizes were calculated and coded for each study. Over 300 microfilmed dissertations covering the past 30 years were examined. Some 2000 ERIC science abstracts were reviewed and suitable studies obtained. Finally, journal articles were reviewed. A total of 400 effect sizes representing 160 studies were produced. The main effect size overall was 0.34. Thus, for all samples considered the experimental science teaching techniques on the average resulted in one-third of a standard deviation improvement over traditional techniques. Mean effect sizes also were calculated for each technique. More than 20 other variables such as class size, community type, and science subject area were cross-tabulated with effect size.     

Associations Between Father Absence and Age of First Sexual Intercourse

Children raised without a biological father in the household have earlier average ages of first sexual intercourse than children raised in father-present households. Competing theoretical perspectives have attributed this either to effects of father absence on socialization and physical maturation or to nonrandom selection of children predisposed for early sexual intercourse into father-absent households. Genetically informative analyses of the children of sister dyads ( N  = 1,382, aged 14–21 years) support the selection hypothesis: This association seems attributable to confounded risks, most likely genetic in origin, which correlated both with likelihood of father absence and early sexual behavior. This holds implications for environmental theories of maturation and suggests that previous research may have inadvertently overestimated the role of family structure in reproductive maturation.     

Interrogating single‐sex classes as a strategy for addressing boys’ educational and social needs

This paper explores the policy of single‐sex classes that is currently being adopted in some schools as a strategy for addressing boys’ educational and social needs. It draws on research in one Australian government, coeducational primary school to examine teachers’ and students’ experiences of this strategy. Interviews with the principal, male and female teachers responsible for teaching the single‐sex classes and the students involved in these classes are used to illustrate the impact and effect of the strategy on pedagogical practices in this particular school. The data are used to raise critical questions about the impact and effects of teachers’ pedagogical practices in light of the current literature and research about single‐sex classes. In this case study, it was found that teachers had a tendency to modify their pedagogical practices and the curriculum to suit stereotypical constructions about boys’ and girls’ supposed oppositional orientations to learning. It is concluded that teacher knowledges and assumptions about gender play an important role in the execution of their pedagogies in the single‐sex classroom.     

Observations of Parent Reactions to Sex-Stereotyped Behaviors: Age and Sex Effects

To examine differential socialization of boys and girls by mothers and fathers, home observations were completed for families of 92 12-month-old children, 82 18-month-old children, and 172 5-year-old children. Mothers gave more instructions and directions than did fathers, while fathers spent more time in positive play interaction. Differences in parents' reactions to 12- and 18-month boys and girls were as expected, with the exception that boys received more negative comment for communication attempts than did girls. The suggestion in the literature that fathers would be more involved in sex typing than mothers was not confirmed in this study. The only 2 significant sex-of-parent x sex-of-child effects occurred at 18 months; fathers gave fewer positive reactions to boys engaging in female-typical toy play, and mothers gave more instruction to girls when they attempted to communicate. We argue that the second year of life is the time when children are learning many new skills and when parents are still experimenting with parenting styles and may well use stereotypical responses when unsure of themselves.     

The Effects of a Student Sampling Plan on Estimates of the Standard Errors for Student Passing Rates

Examined in this study were three procedures for estimating the standard errors of school passing rates using a generalizability theory model. Also examined was how these procedures behaved for student samples that differed in size. The procedures differed in terms of their assumptions about the populations from which students were sampled, and it was found that student sample size generally had a notable effect on the size of the standard error estimates they produced. Also the three procedures produced markedly different standard error estimates when student sample size was small.     

Sex differences in education: exploring children’s gender identity

Abstract

Gender stereotypes associate mathematics and sciences with boys, whereas reading and writing are typically associated with girls. This study investigated sex differences in primary school children’s motivation (confidence and value) across four academic subjects (maths, science, reading and writing) and examined how their identification with stereotypical masculine and feminine traits related to their motivation in these subjects. Five hundred and thirty-two children (aged 9–11, 52% boys), from five UK schools participated. Sex differences in reading and writing motivation were wider than sex differences found in maths and science motivation. Interestingly, the extent to which children identified with feminine traits was a stronger predictor of their reading and writing motivation than their sex. Gender identity provides an innovative approach to the study of sex differences; it challenges the dichotomy inherent within sex differences research and can lead to a more critical and nuanced understanding of sex differences in education.     

Bright girls,mathematics and fear of success

A review of the relevant literature has identified two important areas of sex differences in the field of mathematics. Not only do considerably more boys than girls perform very well in mathematics, but girls, far more frequently than boys, choose not to take intensive mathematics courses once they are no longer compulsory. A variety of factors are frequently cited to explain such consistent sex differences. This paper reports two studies that examine whether there is a relation between fear of success and sex differences in performance and participation in mathematics courses. The evidence provided highlights the effect of environmental pressures. Possible classroom based intervention programs are discussed.     

A meta-analysis of instructional systems applied in science teaching

This article is a report of a meta-analysis on the question: “What are the effects of different instructional systems used in science teaching?” The studies utilized in this meta-analysis were identified by a process that included a systematic screening of all dissertations completed in the field of science education since 1950, an ERIC search of the literature, a systematic screening of selected research journals, and the standard procedure of identifying potentially relevant studies through examination of the bibliographies of the studies reviewed. In all, the 130 studies coded gave rise to 341 effect sizes. The mean effect size produced over all systems was 0.10 with a standard deviation of 0.41, indicating that, on the average, an innovative teaching system in this sample produced one-tenth of a standard deviation better performance than traditional science teaching. Particular kinds of teaching systems, however, produced results that varied from this overall result. Mean effect sizes were also computed by year of publication, form of publication, grade level, and subject matter.     

Child sexual abuse in China: A meta-analysis of 27 studies

Objective

To examine whether Chinese studies of child sexual abuse (CSA) in the general population show lower prevalence rates than other international studies, and whether certain features of these studies may help to account for variation in estimates.

Methods

A meta-analysis and meta-regression were conducted on 27 studies found in the English and Chinese language peer reviewed journals that involved general populations of students or residents, estimated CSA prior to age 18, and specified rates for males or females individually.

Results

Estimates for Chinese females were lower than the international composites. For total CSA for females, the Chinese pooled estimate was 15.3% (95% CI = 12.6–18.0) based on the meta-analysis of 24 studies, lower than the international estimate (Stoltenborgh, van IJzendoorn, Euser, & Bakermans-Kranenburg, 2011) but not significantly. For contact CSA for females, the pooled estimate was 9.5% (95% CI = 7.5–11.5), based on 16 studies, significantly lower than the international prevalence. For penetrative CSA for females, the pooled estimate was 1% (95% CI = 0.7–1.3), based on 15 studies, significantly lower than the international estimate of 15.1%. Chinese men reported significantly less penetrative CSA but significantly more total CSA than international estimates; while contact CSA reported by Chinese and international males appeared to be roughly equivalent. Chinese CSA prevalence estimates were lower in studies from urban areas and non-mainland areas (Hong Kong and Taiwan), and in surveys with larger and probability samples, multiple sites, face-to-face interview method and when using less widely used instruments.

Conclusions

The findings to date justify further research into possible cultural and sociological reasons for lower risk of contact and penetrative sexual abuse of girls and less penetrative abuse of boys in China. Future research should examine sociological explanations, including patterns of supervision, sexual socialization and attitudes related to male sexual prowess.

Practice implications

The findings suggest that future general population studies in China should use well validated instruments, avoid face-to-face interview formats and be careful to maintain methodological standards when sampling large populations over multiple sites.     

Individual participant data meta-analysis of the impact of educational interventions on pupils eligible for Free School Meals

Meta-analysis is the synthesis of findings from research projects, which enables an estimate of the average or pooled effect across various studies. This study presents findings from the intention to treat analysis for a series of educational evaluations in England using a two-stage meta-analysis with standardised outcome data and individual participant data meta-analyses. The research estimates the overall impact of educational trials on pupils eligible for Free School Meals (FSM) and the attainment gap in literacy and mathematics performance between FSM and non-FSM pupils based on analysis of 88 trials and data from over half a million pupils. For the meta-analyses, frequentist and Bayesian multilevel models were used to estimate the individual and pooled effect size across categories of explanatory variables such as age groups (key stages in England) and aspects of the type of interventions (one-to-one, small group, whole class). Results indicated that the overall impact of interventions on the literacy outcomes of FSM pupils was positive, with a pooled effect size of 0.06 (0.03, 0.08). However, for mathematics, no overall effect on FSM pupils was observed. Analysis of the attainment gap indicated that literacy outcomes for FSM pupils were improved by interventions marginally more than for non-FSM pupils (pooled attainment gap 0.01 (−0.01, 0.04)). The risk of bias assessment showed that estimates were consistent across different methodological approaches. Overall, evidence from this study can be used to identify, test and scale educational interventions in schools to improve educational outcomes for disadvantaged pupils.     

Age and Sex Differences in Performance in an 11‐plus Selective Examination

The aim of the study was to investigate age and sex differences in performance in an 11‐plus selective examination. The sample was made up of 3460 pupils who were born in 1981 and who had sat the examination for the first time. Results based on a data set consisting of raw scores in Maltese, English, mathematics, social studies and religious knowledge showed a strong and consistent age effect in all five attainment measures: performance decreased with age from the ‘oldest’ pupils to the youngest’. In regard to sex differences, girls outperformed boys in Maltese, English and religion, with differences being most marked in the two languages. The performance of the two sexes in mathematics and social studies was very similar, with the boys’ performance being slightly, but not significantly, better. These age and sex effects were also evident in the proportions of pupils who passed or failed the examination. Older pupils tended to be more successful than younger pupils, and girls were more likely to pass the examination than boys.     

Do Boys or Girls Make Better Reading Tutors? An Empirical Study to Examine Children's Effectiveness as Tutors Using the Pause,Prompt and Praise Procedures

This study aimed to assess the effects of single‐sex and cross‐gender pairings in the context of the ‘pause, prompt and praise’ procedures for improving reading, the effects of boys as tutors compared with girls as tutors and those of choice in sex of tutor. Four groups were involved in the study: boys tutoring boys, girls tutoring girls, girls tutoring boys and boys tutoring girls. The tutees were 24 Year 7 pupils and the tutors were 24 Year 10 pupils from a large suburban comprehensive school in the Midlands of England. The reading age of each of the tutees was measured both before and after the intervention so that gains in reading age could be evaluated. The results showed that peers could be successfully trained to use the pause, prompt and praise techniques and that these were effective in raising the reading standards of tutees in all four groups. However, little evidence was found to suggest that any of the pairings was any more successful than the others or that the sex of the tutor had any significant effect on the tutoring outcome. On the other hand, however, there was some evidence that choice of tutor sex might have an effect on gains in tutee's measured reading ages     

The potential of immersive virtual reality to enhance learning: A meta-analysis

Research on the impact of immersive virtual reality (I-VR) technology on learning has become necessary with the decreasing cost of virtual reality technologies and the development of high-quality head-mounted displays. This meta-analysis investigates the overall effect size by combining the results of primary experimental studies that reveal the effect of I-VR on learning outcomes. Besides, effect sizes were calculated based on measuring moment, types of measurement, education level, the field of education, control group educational resources, and immersion type subgroups. One hundred five independent results were calculated from 48 primary studies published between 2016 and September 2020, including 39 randomized controlled trials and nine quasi-experimental studies. The sample size of primary studies includes 3179 students, 847 from K12, and 2332 from higher education. Random effects model was used in the calculation of effect size. As a result of the meta-analysis, it was determined that the overall effect size on the learning outcomes of I-VR was small (g = 0.38). Additionally, according to the subgroup analysis results, it was revealed that I-VR significantly differentiated effect size based on educational level, the field of education, and computer-based/traditional sources. There was no significant difference in terms of the other subgroups.
