在选择考研的学校时,考哪个学校是和考哪个专业一样重要的问题,考名校还是考一般的学校,考本校还是外校,这是个问题.我的观点是,还是考名校比较好.     

Learning to engage: how positive attitudes about the news,media literacy,and video production contribute to adolescent civic engagement

Many students enroll in video production courses in high school as part of a vocational, career, or technical program. While there has been an explosion of scholarly work in digital literacy in informal settings, less is known about how digital and media literacy competencies are developed through school-based video production courses. This study explores the relationship between civic engagement and the various multimedia instructional practices used in a high school video production course with a single-school convenience sample and an ethnically diverse population of students. Findings reveal that the best predictors of the intent to participate in civic engagement are having positive attitudes about news, current events, reporting, and journalism. Media literacy attitudes and a range of in-classroom learning experiences with video production are also associated with civic engagement.

Observed peer victimization during early elementary school: continuity, growth, and relation to risk for child antisocial and depressive behavior

The rate at which 266 boys and girls ages 5 to 7 years old were victimized by peers was observed on multiple occasions in kindergarten and first grade. Individual differences in victimization were observed at kindergarten entry and in growth over the subsequent 2 years. Victimization increased for some children but decreased for others. Growth in victimization was reciprocally related to growth in teacher-reported antisocial and depressive behavior for boys. For girls, kindergarten victimization was related to growth in parent-reported antisocial behavior, teacher-reported depressive behavior to growth in victimization, and growth in victimization to parent-reported depression. At a short-term group level, antisocial behavior had a lagged suppressive effect on victimization for boys but a facilitating effect for girls.     

An examination of the effectiveness of a sexual ethics curriculum

This article presents early evaluation data on the effectiveness of an ethics-based sex education program, the Sexual Ethics for a Caring Society Curriculum (SECS-C), which strives to develop adolescents’ thinking about sex so that they might act ethically in relation to other people and reflect ethically upon sexual messages and events in the world around them. Unlike typical evidence-based curricula that measure prevention goals from a health perspective, effectiveness was measured in terms of attitude change. Seventy-nine 9th graders from 7 diverse classrooms at a charter school received 8 lessons from the curriculum. Pre and post measures assessed belief in rape myths (the Illinois Rape Myth Acceptance Scale) and bystanderism (the Bystander Attitude Scale, Revised (BAS-R)). The students showed improvements with regard to rape myth attitudes but not with regard to their beliefs in the likelihood of intervening in troublesome sexual situations.     

Infants' Reliance on a Social Criterion for Establishing Word-Object Relations

The language children hear presents them with a multitude of co-occurrences between words and things in the world, and they must repeatedly determine which among these manifold co-occurrences is relevant. Social factors—such as cues regarding the speaker's referential intent—might serve as one guide to whether word-object covariation should be registered. In 2 studies, infants (15–20 months and 18–20 months in Studies 1 and 2, respectively) heard novel labels at a time when they were investigating a single novel object; in one case the label was uttered by a speaker seated within the infant's view and displaying concurrent attention to the novel toy (coupled condition), whereas in the other case the label emanated from a speaker seated out of the infant's view (decoupled condition). In both studies, subsequent comprehension questions indicated that infants of 18–20 months registered a stable link between label and object in the coupled condition, but not in the decoupled condition, despite the fact that covariation between label and object was equivalent in the 2 conditions. Thus, by 18–20 months children are inclined to establish a mapping between word and object only when a speaker displays signs of referring to that object.     

Role of Significant Life Experiences in Building Environmental Knowledge and Behavior Among Middle School Students

Significant life experience research suggests that the presence of role models, time outdoors, and nature-related media foster pro-environmental behavior, but most research is qualitative. Based on a random sample of middle school students in North Carolina, USA, we found limited positive associations between presence of a role model and time outdoors with behavior and a negative association between watching nature television and environmental knowledge. The strongest predictors of environmental knowledge and behavior were student/teacher ratio and county income levels, respectively. We also found that Native Americans engaged in environmental behaviors more than Caucasians, and that African American and Hispanic students had lower levels of environmental knowledge. Accordingly, life experiences appear less important than promoting small class sizes and addressing challenges associated with lower incomes in schools.     

A Community College Instructor’s Reflective Journey Toward Developing Pedagogical Content Knowledge for Nature of Science in a Non-majors Undergraduate Biology Course

Research supports an explicit-reflective approach to teaching about nature of science (NOS), but little is reported on teachers’ journeys as they attempt to integrate NOS into everyday lessons. This participatory action research paper reports the challenges and successes encountered by an in-service teacher, Sarah, implementing NOS for the first time throughout four units of a community college biology course (genetics, molecular biology, evolution, and ecology). Through the action research cycles of planning, implementing, and reflecting, Sarah identified areas of challenge and success. This paper reports emergent themes that assisted her in successfully embedding NOS within the science content. Data include weekly lesson plans and pre/post reflective journaling before and after each lesson of this lecture/lab combination class that met twice a week. This course was taught back to back semesters, and this study is based on the results of a year-long process. Developing pedagogical content knowledge (PCK) for NOS involves coming to understand the overlaps and connections between NOS, other science subject matter, pedagogical strategies, and student learning. Sarah found that through action research she was able to grow and assimilate her understanding of NOS within the biology content she was teaching. A shift in orientation toward teaching products of science to teaching science processes was a necessary shift for NOS pedagogical success. This process enabled Sarah’s development of PCK for NOS. As a practical example of putting research-based instructional recommendations into practice, this study may be very useful for other teachers who are learning to teach NOS.
