The paper deals with the investigation of gender differences in performances in mathematics for Italian students at the end of lower secondary school. The study is based on a new large-scale assessment test developed and administered by the National Evaluation Institute for the School System. Given the evidence in the literature which favors males, performances of female and male students are compared using different approaches. Scores proposed by educational experts based on item subgroups were considered, while a model-based approach was used within item response theory. The results revealed a significant advantage to males in overall performance, while no meaningful differences were observed with respect to item domain and type. An interpretable item map was developed crossing expert opinions with IRT abilities, and plausible proficiency levels were defined. According to the map-based student classification, a relatively lower percentage of females fell into the highest proficiency groups with respect to males.  相似文献

The genetic and environmental origins of individual differences in mathematical self-evaluation over time and its association with later mathematics achievement were investigated in a UK sample of 2138 twin pairs at ages 9 and 12. Self-evaluation indexed how good children think they are at mathematical activities and how much they like those activities. Mathematics achievement was assessed by teachers based on UK National Curriculum standards. At both ages self-evaluation was approximately 40% heritable, with the rest of the variance explained by non-shared environment. The results also suggested moderate reciprocal associations between self-evaluation and mathematics achievement across time, with earlier self-evaluation predicting later performance and earlier performance predicting later self-evaluation. These cross-lagged relationships were genetically rather than environmentally mediated.  相似文献

近年来频繁发生的食品安全事件引发了人们对于食品安全问题的高度关注,全球化、信息化也使得食品安全成为全世界共同关注的话题。它不仅关系着人们的生命安全与身体健康,还关系着社会秩序的稳定,与政治、经济、社会、文化重要相关。文章试图从社会学的角度出发,以社会控制为切入点,将食品安全问题置于中国社会转型和全球信息社会背景之下进行考察,以期为解决食品安全问题提供思路。  相似文献

为了从根本上解决教育技术学专业内容宽泛,理论不深、技术不精、就业不畅的问题,教育技术学专业可走两条路线发展:第一条是走专门的技术应用路线,课程设置以技术、实践应用为主;第二条是走专门的教师教育专业路线。  相似文献

在中国古代,"传"和"记"是彼此独立的两个门类,现代意义上的自传并不存在。自传的出现与启蒙运动密切相关。1898年之后,随着西学东渐的发生,现代个人遭遇到了传统共同体的崩塌。为了重新建立起一套行之有效的现代共同体建制,从而稳固个体的身份认同,新出现的知识分子发现了自传所蕴藏的变革力量,他们纷纷在新的知识框架内对中国自传的历史进行了梳理,意在重塑"新民"的理想人格,完成了自传的现代转型。  相似文献

Context-based science courses stimulate students to reconstruct the information presented by connecting to their prior knowledge and experiences. However, students need support. Formative assessments inform both teacher and students about students’ knowledge deficiencies and misconceptions and how students can be supported. Research on formative assessments suggests a positive impact on students’ science achievement, although its success depends on how the formative assessment is implemented in class. The aim of this study was to provide insights into the effects of formative assessments on achievement during a context-based chemistry course on lactic acid. In a classroom action research setting, a pre-test/post-test control group design with switching replications was applied. Student achievement was measured in two pre-tests, two post-tests and a retention test. Participants were Grade 9 students from one secondary school in the Netherlands. Repeated-measures analysis showed a significant effect of formative assessments on students’ achievement. During the implementation of the formative assessments, intriguing discussions emerged between students, between students and teacher, and between teachers. Adding formative assessments to context-based approaches reinforces their strength to meet with the current challenges of chemistry education. Formative assessments affect students’ achievement positively and stimulate feedback between students and teacher(s).  相似文献

The science achievement of 226 5th graders from districts that have a kit-based inquiry science curriculum supported by intensive professional development (PD) is compared with data from a group of 173 5th graders from other districts that use nonkit science materials and do not have systematic science PD for teachers. Within the kit-based project, the sample of project teachers is stratified to select teachers with a high number of science PD hours versus those with few hours. While there were no significant differences in the mean total scores for kit-based students with low PD versus high PD teachers, the kit-based classrooms scored significantly higher than students in nonkit classrooms on both the pretest and posttest, though there were significantly more minutes of science instruction in the nonkit classrooms. Finally, nonkit teachers taught more units of shorter length and reported lower levels of preparedness to use reform pedagogical approaches.  相似文献
