Although a number of studies document the fact that adult males interrupt females more often than females interrupt males, less is known about whether this behavior is also true of younger boys and girls. This study examined some aspects of dominant-submissive sex role behavior in preschool children and their teachers during conversation at the snack table. It asked whether there was any difference in the number of times girls and boys interrupted their teacher, and whether there was any difference in the number of times the teacher interrupted boys or girls. In succeeding observations, researchers investigated whether girls or boys were assigned the privilege of passing snack more frequently.In Investigation 1 nine boys and nine girls, 4 years of age, were observed talking with a variety of student teachers in a naturalistic snack setting, and checklists were kept of the number of teacher-child, child-teacher interruptions during conversation. In Investigation 2, tallies were kept of the number of times boys and girls assumed the dominant roles of distributing snacks and snack materials.Results indicted that during conversation, boys interrupted their teachers more frequently than the girls did (p > .03). Teachers interrupted girls more frequently than they interrupted boys (p > .02). No significant differences were found in the frequency of participation by boys or girls in passing snack. Results are discussed in relation to the teacher's role in teaching dominant-submissive sex role behaviors to children.  相似文献

This study explores biology undergraduates' misconceptions about genetic drift. We use qualitative and quantitative methods to describe students' definitions, identify common misconceptions, and examine differences before and after instruction on genetic drift. We identify and describe five overarching categories that include 16 distinct misconceptions about genetic drift. The accuracy of students' conceptions ranges considerably, from responses indicating only superficial, if any, knowledge of any aspect of evolution to responses indicating knowledge of genetic drift but confusion about the nuances of genetic drift. After instruction, a significantly greater number of responses indicate some knowledge of genetic drift (p = 0.005), but 74.6% of responses still contain at least one misconception. We conclude by presenting a framework that organizes how students' conceptions of genetic drift change with instruction. We also articulate three hypotheses regarding undergraduates' conceptions of evolution in general and genetic drift in particular. We propose that: 1) students begin with undeveloped conceptions of evolution that do not recognize different mechanisms of change; 2) students develop more complex, but still inaccurate, conceptual frameworks that reflect experience with vocabulary but still lack deep understanding; and 3) some new misconceptions about genetic drift emerge as students comprehend more about evolution.  相似文献

This paper describes results from field testing of middle-school math formative assessments alongside professional development and instructional resources. We employed a randomised, controlled design to address the question: Does using our formative assessment strategies improve student performance on assessments of key mathematical ideas relative to a comparison group? This study also provided data on the instructional sensitivity of the assessments, which is part of the validation needed for formative assessments. Teachers were recruited from two districts and seven middle schools. Nineteen treatment and 17 comparison group teachers and their students were included in study analyses. Scores on extended response and short-answer questions indicated that students in the treatment group performed better than students in the comparison group who received the formative assessments alone. These findings demonstrate both the feasibility and value of including performance task-types in a brief assessment context.  相似文献

In an effort to expand existing research on the barriers of instructors experience in online learning environments (OLEs), a qualitative study was conducted at a large mid-Atlantic university. Six instructors teaching in different OLE formats (e.g., asynchronous, hybrid, and synchronous via videoconferencing) participated in two focus groups in order to explore their emotional experiences and ways to regulate the emotions when teaching in OLEs. The overarching themes included emotions of feeling (a) restricted, (b) stressed, (c) devalued, (d) validated, and (e) rejuvenated. The article also provides practical strategies on how participating instructors attempted to manage the challenging emotions. A consensus among all participants is that continuous dialog in a community of practice about strategies to enhance OLEs is imperative.  相似文献

The research investigated the association between school engagement and adult education and occupation outcomes, within the context of a 1985 Australian longitudinal national cohort study of the factors affecting children's long‐term health and well‐being. School engagement may be more modifiable than other factors related to academic success, such as academic attainment, which is influenced by family background. A School Engagement Index was constructed using questionnaire items on school enjoyment and boredom. Related school engagement items included learner self‐concept, motivation to learn, sense of belonging, participation in school or extra‐mural activities, and enjoyment of physical activity. In 2004–2006, participants (aged 26 to 30 years) reported their highest level of education achieved and current occupation. Potential covariates included age, sex, markers of socio‐economic status in childhood, personality and school‐level variables (i.e., number of students, single sex versus co‐education; government, private or independent). Logistic regression was used to estimate the odds of achieving post‐compulsory school education and achieving higher status occupations. Findings revealed that each unit of school engagement was independently associated with a 10% higher odds (OR 1.10 95% CI 1.01,1.21) of achieving a post‐compulsory school education. Maternal education, self‐concept as a learner, motivation to learn, all also significantly predicted achieving post‐compulsory school education. School engagement was found to mediate the association between the personality characteristic of agreeableness and education outcomes. Higher school engagement was also independently associated with achieving higher status occupations 20 years later (OR 1.11 95% CI 1.03, 1.20). Importantly, this was independent of a host of background factors.  相似文献

This study investigates the effect of word study instruction on the orthographic knowledge of college students enrolled in a developmental reading course. Results revealed significantly greater improvement in orthographic knowledge in students who received word study instruction when compared with those in a control group, suggesting that the word study approach was effective for these students. Because of the influence of orthographic knowledge on spelling, writing and reading, additional research is merited to examine how word study intervention impacts the reading behaviours and academic achievement of college students enrolled in developmental education courses.  相似文献
