Facebook status updates provided the data for a study about the transition learning experiences of 1st-year university students. Strict ethical guidelines were proposed by the PhD researcher from the outset of the study. Anonymity was considered important for the approved ethical clearance for both the university and the participants. Phenomenography was adopted and adapted for the study because it both conceptually and methodologically managed anonymity as well as questions of authenticity. An ethical dilemma arose during the research because the archival parameters were expanded by the researcher to allow the collection of data from the participants’ network. Questions of consent in an online space and how to report findings, which included data from people unaware of their involvement in the research, needed to be considered. 相似文献

This meta-analysis examined the relationship between prenatal maternal stress and/or anxiety and the outcomes of children aged 3 months to 9 years. Of the 8754 studies published before June 2021 that were synthesized, 17 conducted in Western countries were included in the meta-analysis (Ntotal = 23,307; Mmales 54%; Methnicity White 77%, Pacific 15%, African American/Black 10%, Middle Eastern 7%, Eastern 8%). Effect sizes ranged from −0.41 to 0.15. A weak negative association was found between prenatal stress and/or anxiety exposure and children's general intellectual development. Associations varied based on the type of exposure. Findings are limited to developed counties and cannot be generalized to low- and middle-income countries. Directions for maternal prenatal intervention and future studies are discussed. 相似文献

To increase participation of students of color in science graduate programs, research has focused on illuminating student experiences to inform ways to improve them. In biology, Black students are vastly underrepresented, and while religion has been shown to be a particularly important form of cultural wealth for Black students, Christianity is stigmatized in biology. Very few studies have explored the intersection of race/ethnicity and Christianity for Black students in biology where there is high documented tension between religion and science. Since graduate school is important for socialization and Black students are likely to experience stigmatization of their racial and religious identity, it is important to understand their experiences and how we might be able to improve them. Thus, we interviewed 13 Black Christian students enrolled in biology graduate programs and explored their experiences using the theoretical lens of stigmatized identities. Through thematic content analysis, we revealed that students negotiated experiences of cultural isolation, devaluation of intelligence, and acts of bias like other racially minoritized students in science. However, by examining these experiences at the intersection of race/ethnicity and religion, we shed light on interactions students have had with faculty and peers within the biology community that cultivated perceptions of mistrust, conflict, and stigma. Our study also revealed ways in which students' religious/spiritual capital has positively supported their navigation through biology graduate school. These results contribute to a deeper understanding of why Black Christian graduate students are more likely to leave or not pursue advanced degrees in biology with implications for research and practice that help facilitate their success. 相似文献

The purpose of this study was to assess preservice teachers’ views of Nature of Science (NOS), identify aspects that were challenging for conceptual change, and explore reasons why. This study particularly focused on why and how some concepts of NOS may be more easily altered than others. Fourteen preservice science teachers enrolled in a NOS and Science Inquiry course participated in this study. Data were collected by using a pre/post format with the Views of Nature of Science questionnaire (VNOS-270), the Views of Scientific Inquiry questionnaire (VOSI-270), follow-up interviews, and classroom artifacts. The results indicated that most students initially held naïve views about certain aspects of NOS like tentativeness and subjectivity. By the end of the semester, almost all students dramatically improved their understanding about almost all aspects of NOS. However, several students still struggled with certain aspects like the differences between scientific theory and law, tentativeness, and socio-cultural embeddedness. Results suggested that instructional, motivational, and socio-cultural factors may influence if and how students changed their views about targeted NOS aspects. Students thought that classroom activities, discussions, and readings were most helpful to improve their views about NOS. The findings from the research have the potential to translate as practical advice for teachers, science educators, and future researchers. 相似文献

This study evaluated the test–retest reliability of two parenting measures: the Parent Behavior Importance Questionnaire‐Revised (PBIQ‐R) and Parent Behavior Frequency Questionnaire‐Revised (PBFQ‐R). These self‐report parenting behavior assessment measures may be utilized as pre‐ and post‐parent education program measures, with parents as well as nonparent respondents. The questionnaires are based on the parent development theory, with the parenting behaviors corresponding to theory and current parenting literature. Thus, respondents' relative weighting of importance (PBIQ‐R) or frequency (PBFQ‐R) of positive, supportive parenting as well as negative behaviors may be determined through questionnaire responses. Test–retest reliability estimates suggest psychometric strength. Results are discussed relative to parenting theory and research, as well as school psychology policy and practice. © 2011 Wiley Periodicals, Inc. 相似文献

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. 相似文献

Little is known about how specific components of working memory, namely, attentional processes including response inhibition, sustained attention, and cognitive inhibition, are related to reading decoding and comprehension. The current study evaluated the relations of reading comprehension, decoding, working memory, and attentional control in 1,134 adolescent students. Path analyses were used to assess the direct and indirect effects of working memory and aspects of attentional control on reading comprehension and decoding. There were significant direct effects of working memory, sustained attention, and cognitive inhibition on reading comprehension, but not decoding. There was a significant direct effect of working memory and response inhibition on decoding, but not comprehension. These results suggest that different aspects of attentional control are important for decoding versus comprehension. 相似文献

The objective of this study was to describe prevalent informal sources of information about sex and examine associations between informal sources of information about sex and sexual risk outcomes among sexually experienced adolescents. Work involved the secondary analysis of data from the Minnesota Student Survey, a statewide survey to monitor priority risk and protective health behaviors. The study sample included 22,828 sexually experienced adolescents aged 13–20 years. Multivariate logistic regression analyses examined associations between adolescents' informal sources of information about sex and three sexual risk outcomes. Peers and siblings were the most commonly reported source of information about sex. Ninth-graders who reported parents or parents plus peers/siblings as a source of information about sex had significantly lower odds of having multiple sex partners in the past year. Ninth-graders who reported any informal source of information about sex had significantly lower odds of unprotected intercourse at last sex. Ninth-graders and 12th-graders who reported any informal source of information about sex had significantly lower odds of lifetime pregnancy involvement. Findings suggest information about sex from people in adolescents' everyday lives has the potential to diminish the likelihood of involvement in sexual risk behaviors. To maximize effectiveness, formal sex education programs should engage informal sources of information about sex in adolescents' everyday lives. 相似文献

The purpose of this study was to examine and compare the decision process for physicians and pharmacists when considering medications to treat patients with panic disorder. A second‐order confirmatory factor analysis modeling physicians' prescribing influences revealed high factor loadings for efficacy considerations and side effects in conjunction with patient characteristics. A multisample analysis using the physician model revealed that pharmacists also consider the same factors important. Both health care professionals were concerned about the patient's quality of care, recovery, and medication efficacy. 相似文献
