US adolescents initiate sex at increasingly younger ages, yet few pregnancy prevention interventions for children as young as 10–12 years old have been evaluated. Sixteen Washington, DC schools were randomly assigned to intervention versus control conditions. Beginning in 2001/02 with fifth-grade students and continuing during the sixth grade, students completed pre-intervention and post-intervention surveys each school year. Each year, the intervention included 10–13 classroom sessions related to delaying sexual initiation. Linear hierarchical models compared outcome changes between intervention and control groups by gender over time. Results show the intervention significantly decreased a rise over time in the anticipation of having sex in the next 12 months among intervention boys versus control boys, but it had no other outcome effects. Among girls, the intervention had no significant outcome effects. One exception is that for both genders, compared with control students, intervention students increased their pubertal knowledge. In conclusion, a school-based curriculum to delay sexual involvement among fifth-grade and sixth-grade high-risk youths had limited impact. Additional research is necessary to outline effective interventions, and more intensive, comprehensive interventions may be required to counteract adverse circumstances in students' lives and pervasive influences toward early sex.

Observations were made of the progressive change in the cognitive development of 141 students over the course of their secondary education in an Australian private school. Cognitive development was measured in years 8, 10 and 12 usingBond's Logical Orerations Test. Rasch analysis of each of the data sets provided ability estimates for students in the year groups of 1993 (year 8), 1995 (year 10) and 1997 (year 12). Twenty-nine students from the year group of 1993 were tested on all three occasions. We analysed data from these 29 students in order to investigate the children's cognitive development across years 8, 10 and 12. We also examined the influence of the Cognitive Acceleration through Science Education (CASE)Thinking Science program on the cognitive development and scholastic achievement of these students. We found increased mental growth between years 8 and 10 for most students in theThinking Science cohort, which could not be predicted from their starting levels. There was a significant correlation between cognitive development and the scholastic achievement of these students. Although boys as a group were more advanced in cognitive development than girls in years 8 and 10, no difference was found in the rate of cognitive change based on sex up to year 10. However girls showed cognitive gains across years 10–12 which were not found in boys. The students who were new to the school also showed increased cognitive development in years 11 and 12. Students who had experienced theThinking Science course were more cognitively developed than students who joined the school after the intervention had taken place. This study supports the claim of Adey and Shayer that there is a relationship between cognitive development and scholastic achievement, even though we used different measures of cognitive development and scholastic achievement.  相似文献

Abstract

This article presents evidence from a large-scale randomized controlled trial of the effects of four supplemental reading comprehension curricula (Project CRISS, ReadAbout, Read for Real, and Reading for Knowledge) on students’ understanding of informational text. Across 2 school years, the study included 10 school districts, more than 200 schools, and more than 10,000 fifth-grade students. Schools interested in implementing 1 of the 4 supplemental curricula were randomly assigned to 1 of 4 treatment groups or to a control group. The impact analyses in the study's first year revealed a statistically significant negative impact of Reading for Knowledge on students’ reading comprehension scores and no other significant impacts. The impact of ReadAbout was positive and significant in the study's second year among teachers with 1 year of experience using the intervention.  相似文献

A one-year lag was found between the effect of an intervention intended to promote formal operational thinking in students initially 11 or 12 years of age and the appearance of substantial science achievement in the experimental groups. A one-year lag was also reported on cognitive development: Whereas at the end of the two-year intervention the experimental groups were up to 0.9σ ahead of the control groups, one year later the differential on Piagetian measures had disappeared, but the experimentals now showed better science achievement of even greater magnitude. Although the control groups showed normal distribution both on science achievement and cognitive development, the experimental groups showed bi- or trimodal distribution. Between one-half and one-quarter of the students involved in the experiment in different groups showed effects of the order of 2σ both on cognitive development and science achievement; some students appeared unaffected (compared with the controls), and others demonstrated modest effects on science achievement. An age/gender interaction is reported: the most substantial effects were found in boys initially aged 12+ and girls initially 11+. The only group to show no effects was boys initially aged 11+. It is suggested that the intervention methods may have favored the abstract analytical learning style as described by Cohen 1986.  相似文献

This article presents findings from a study investigating the effects of a middle school counseling intervention, using a specially designed curriculum, on participating students' attitudes, self-efficacy, and performance in mathematics. Hierarchical linear modeling was used to test for main effects between condition and sex and condition x sex interaction effects on all outcome measures across 3 time points: pre-intervention, post-intervention, and follow-up. At pre-intervention, boys were significantly higher than girls on all variables except for performance in math. Models for growth indicated that students in the experimental group improved at a significant rate compared to girls in the control group on motivation, value, enjoyment, and confidence in mathematics. Implications of the findings are therefore particularly relevant for girls, who may benefit from interventions designed to increase their attitudes and self-efficacy for mathematics.  相似文献

ABSTRACT

Sexually active college students in the United States have alarming rates of unplanned pregnancy and sexually transmitted infections. Varying degrees of sexual health knowledge and attitudes among college students are an outcome of sexuality education in the K-12 school systems with abstinence-only or comprehensive focus. Community college students (n = 737) aged 18–24 years, 57% from a college in an abstinence-only sex education state and 43% from a college in a comprehensive sex education state, both in the Mid-Atlantic region, took the Sexual Health Survey in October 2016, which measures sexual health knowledge and attitudes. Gender and ethnicity differences, as well as other sources of sexuality information were evaluated. Students from the comprehensive sex education state, New Jersey had higher sexual health knowledge and attitude scores than the students from the abstinence-only sex education state, Pennsylvania. Male students in New Jersey scored significantly higher in sexual health knowledge compared to male students in Pennsylvania, while female students in New Jersey had higher sexual health knowledge scores compared to the male students. Analysis of ethnicity revealed the New Jersey college sample had healthier sexual attitudes as compared to the Pennsylvania college sample, with notable distinction among Black students. The Internet, friends, and personal experiences were chosen by 75% of all students across both colleges as the top reported sources of sexuality information. In addition to advocating for comprehensive sex education, recommendations are made for sexual health initiatives in community colleges to provide sexual health instruction and support.  相似文献

Which kinds of content- and language-integrated interventions can better support mathematical learning, depending on students’ language background, as measured by communication on the discourse level or additional lexical training on the word level? A control trial compared interventions with two different materials (discursive versus lexical-discursive, each 5 × 90?min.) with respect to the dependent variable of conceptual and procedural knowledge for fractions. The effects are investigated differentially for four language groups: monolinguals versus bilinguals, each with higher versus lower German language proficiency (n = 343). For both interventions, the ANOVA shows an increase of mathematical knowledge for the experimental group, which is significantly higher than for the control group, but no significant difference between the interventions. The intervention with lexical-discursive materials led to a slightly higher increase of knowledge in the post test, but the discursive intervention was superior in the follow up test. Monolingual and multilingual students had similar patterns of growth without differential pattern. However, the proficient monolingual students tend to profit more from the interventions, especially from the lexical-discursive intervention.  相似文献

The purpose of this correlational study was to examine the possible relationships among children's extracurricular toy-playing habits, sex-role orientations, spatial abilities, and science achievement. Data were gathered from 282 midwestern, suburban, fifth-grade students. It was found that boys had significantly higher spatial skills than girls. No significant differences in spatial ability were found among students with different sex-role orientations. No significant differences in science achievement were found between girls and boys, or among students with the four different sex-role orientations. Students who had high spatial ability also had significantly higher science achievement scores than students with low spatial ability. Femininely oriented boys who reported low playing in the two-dimensional, gross-body-movement, and proportional-arrangement toy categories scored significantly higher on the test of science achievement than girls with the same sex-role and toy-playing behavior.  相似文献

African-American youth suffer disproportionately from sexual risk consequences including unintended pregnancy and sexually transmitted infections. Parents educating young people about sex may be one approach to reduce sexual risk behaviour among this population. The purpose of this study was to determine young people's perceptions of parents' attitudes about sex and assess whether these perceptions affect sexual risk. Data were collected from 560 African-Americans, aged 9–19 years. Most (73.4%) thought their parents would be unhappy if they got someone pregnant/got pregnant, with more girls feeling this way than boys (p = 0.013). Sexually active boys who thought their parents would be unhappy if they got someone pregnant reported fewer sexual partners within the past year (p < 0.01) and fewer sexual encounters in the past 3 months (p = 0.01) compared to those whose parents would think otherwise. Our research illustrates that parents' explicit and unstated attitudes are apparent to their offspring, and young people's perceptions can impact their risk behaviour. As such, early and often sex education communication between parents and young people should be encouraged. Sexual health interventions encouraging parents to educate about sex and its consequences could enhance the health of young African-Americans.  相似文献

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  相似文献

Mothers have an important role to play in teaching their children about sexual issues and shaping children’s sexual knowledge, attitudes and behaviours. In many cases, however, mothers themselves need help and support. This study was conducted to examine the effects of a sex education programme on the knowledge and attitudes of the mothers of pre-school children. Eighty mothers of pre-school children were randomly divided into an experimental and a control group. The experimental group received an education and training programme delivered over two 2-h sessions. The control group received no such intervention. Researcher-constructed knowledge and attitude questionnaires were completed by both groups before and one month after the intervention. Findings showed no significant differences between the two groups in terms of knowledge and attitudes before the training. After the education and training intervention, however, there was a significant increase in the mean score for both knowledge and attitudes in the experimental group compared to the control group. Study findings suggest that the sex education programme for the mothers of pre-school children can improve their knowledge and attitudes.  相似文献

Researchers have highlighted the increasing problem of loud sounds among young people in leisure-time environments, recently even emphasizing portable music players, because of the risk of suffering from hearing impairments such as tinnitus. However, there is a lack of studies investigating compulsory-school students’ standpoints and explanations in connection with teaching interventions integrating school subject content with auditory health. In addition, there are few health-related studies in the international science education literature. This paper explores students’ standpoints on loud sounds including the use of hearing-protection devices in connection with a teaching intervention based on a teaching–learning sequence about sound, hearing and auditory health. Questionnaire data from 199 students, in grades 4, 7 and 8 (aged 10–14), from pre-, post- and delayed post-tests were analysed. Additionally, information on their experiences of tinnitus as well as their listening habits regarding portable music players was collected. The results show that more students make healthier choices in questions of loud sounds after the intervention, and especially among the older ones this result remains or is further improved one year later. There are also signs of positive behavioural change in relation to loud sounds. Significant gender differences are found; generally, the girls show more healthy standpoints and expressions than boys do. If this can be considered to be an outcome of students’ improved and integrated knowledge about sound, hearing and health, then this emphasizes the importance of integrating health issues into regular school science.  相似文献

Students with poorly developed authorial identity may be at risk of unintentional plagiarism. An instructional intervention designed specifically to improve authorial identity was delivered to 364 psychology students at three post‐1992 universities in London, UK, and evaluated with before‐and‐after measures of beliefs and attitudes about academic authorship, using the Student Authorship Questionnaire. Changes in questionnaire scores showed that the intervention led to significantly increased confidence in writing, understanding of authorship, knowledge to avoid plagiarism, and top‐down approaches to writing, and significantly decreased bottom‐up and pragmatic approaches to writing. For understanding of authorship, knowledge to avoid plagiarism and pragmatic approaches to writing, significant intervention by year of study interaction effects showed that the greatest improvements were among year one undergraduates. Direct evaluative feedback showed that 86% of students believed the intervention helped them avoid plagiarism and 66% believed it helped them write better assignments. Post‐intervention focus groups revealed changed student understandings about authorial identity and academic writing. The results show that interventions can help students avoid unintentional plagiarism by adopting more authorial roles in their academic writing. Further research could explore other influences on authorial identity, and examine the impact of authorial identity interventions on other outcome indicators.  相似文献

Abstract

This study examined two widely available light-touch, writing-based mindset interventions: one that targeted students’ purpose for learning and one that aimed to increase students’ growth mindset. In order to examine the potential mechanisms underlying previously reported effects of mindset interventions, we analyzed these interventions’ effects on low-income, ethnic minority adolescents’ academic outcomes, task persistence, task-relevant anxiety, critical motivation, and sense of belonging. Results indicated that the purpose for learning intervention had a small negative impact on students’ self-reported grades the following year, and null results for the other outcomes. The growth mindset intervention was administered one year following the purpose for learning intervention and we found no evidence of treatment impacts on any outcomes. Analyses of treatment impact moderation suggested that certain student characteristics, such as student gender and race could play a role, but most of these tests also presented null results. The primarily null results of both interventions suggest that further study is needed to determine the effectiveness of one-time, self-administered mindset interventions across a variety of contexts and student populations.  相似文献

In an attempt to accelerate the development of formal operations in average young adolescents, intervention lessons relating to all formal schemata were designed in the context of school science courses. Over a period of two years, up to 30 intervention lessons were given by science teachers to their classes in eight schools. Boys who started the program aged 12+ showed a pre-posttest effect size on Piagetian tests of 0.89 SD compared with control classes. In terms of British norms for the development of operational thinking this was a mean change from the 51st to the 74th percentile. Neither the middle school students nor the 12+ girls showed greater gain than the controls. Gains were shown by girls in one 11+ class and in the two 11+ laboratory classes. In the laboratory school students given intervention lessons by the researchers maintained their gains over controls in formal operations at a delayed posttest one year after cessation of the program. There was no effect on tests of science achievement during the intervention. It was argued that the interventions needed to be accompanied by in-service training designed to enable teachers to change their teaching style in line with their students' increased operational thinking capacity.  相似文献

The aim was to develop, implement, and evaluate a physical education-based coping training program for vocational students. Two vocational schools participated in the quasi-experimental pilot study (EPHECT I). One school received the intervention (intervention group: n?=?434), while the other school maintained regular physical education classes (control group: n?=?430). Repeated measures ANCOVAs were used to examine the effects on coping and perceived stress. Additionally, effects were compared among students who reported low versus elevated life satisfaction. Finally, the implementation rate was considered as a moderating factor. Overall, no significant time by group effects were found between the intervention group and the control group. However, a reduction in maladaptive coping occurred among students of the intervention group who reported low life satisfaction. The implementation rate did not moderate the findings. Despite a relatively low implementation rate, the intervention program reduced maladaptive coping strategies in adolescents with low life satisfaction. Program monitoring needs to be increased in future research.  相似文献

Data are presented on the trend in sex differences in science achievement of the total population of 15 year old students in Western Australia over the period 1972‐85 inclusive. Since 1979 the science achievement of boys and girls has been approximately equal. This finding is attributed to the fact that, in Western Australia, at lower secondary school level, boys and girls are exposed to a common science curriculum for a common amount of instructional time. A discussion of the differential course taking hypothesis as an explanation for sex differences in science achievement found in other large‐scale studies is presented. Some evidence of the possible success of intervention strategies aimed at increasing the involvement of girls in science is given.  相似文献

The present study reports the short‐ and long‐term effects of an anti‐bullying intervention program based on a particular set of curricular activities that aimed to create classroom opportunities for awareness raising, self‐reflection, and problem‐solving situations relevant to bullying. The core of the intervention was a four‐week period during which a series of activities were organised in each individual class. An experimental pre‐test/post‐test design with a control group was used. The sample consisted of 454 pupils (206 control: 123 boys and 83 girls; and 248 experimental: 126 boys and 122 girls) drawn from the fourth‐ to sixth‐grade classrooms of 10 primary schools in central Greece (mean age = 10.23, SD = .84). Data were collected using self‐report measures, before the intervention (December 2003), immediately after the intervention, at the end of the same school year (May 2004), and six months afterwards (November 2004). The results indicated that the program contributed to a positive reduction in outsider behaviour (children remaining uninvolved and thus silently allowing bullying to continue) and enhanced students’ self‐efficacy beliefs for both assertion and intervening in bully/victim incidents. However, the long‐term effectiveness of the program was limited. These findings have important implications for interventions to tackle the negative effects associated with bullying in schools.  相似文献

This study aimed to assess associations between school HIV education and protective sexual behaviors and sexually transmitted disease (STD)/HIV diagnosis with a representative sample of male and female high school students. Data from male and female adolescent participants in the 1999, 2001 and 2003 Massachusetts Youth Risk Behavior Survey (n = 12,243) were analyzed. Adjusted regression analyses stratified by gender were conducted to assess relationships between school HIV education exposure and the following outcomes: no sexual initiation, condom use at last sex, no multiple sex partners in the past three months and no history of STD/HIV diagnosis. Participants were mostly White (75%) and were 51% male; the subsample of sexually active students was younger than the total sample but was otherwise similar in demographics. School HIV education was reported by 93% of our sample and was significantly related to sexual initiation among boys (odds ratio = 1.9, 95% confidence interval = 1.4–2.7) but not girls. Among sexually experienced students (n = 4752), boys reporting exposure to school HIV education were significantly more likely to report condom use (odds ratio = 2.2, 95% confidence interval = 1.6–3.1), no multiple sex partners (odds ratio = 3.2, 95% confidence interval = 2.3–4.4) and no STD/HIV diagnosis (odds ratio = 3.2, 95% confidence interval = 2.0–5.0); girls reporting such exposure were significantly more likely to report no multiple sex partners (odds ratio = 2.2, 95% confidence interval = 1.3–3.6). In conclusion, exposure to school HIV education is associated with sexual protective behaviors and reduced likelihood of STD/HIV diagnosis for boys but less so for girls, suggesting the need for more gender‐tailored approaches to school HIV education.  相似文献
