In typical development, gestures precede and predict language development. This study examines the developmental sequence of expressive communication and relations between specific gestural and language milestones in toddlers with autism spectrum disorder (ASD), who demonstrate marked difficulty with gesture production and language. Communication skills across five stages (gestures, word approximations, first words, gesture-word combinations, and two-word combinations) were assessed monthly by blind raters for toddlers with ASD participating in an randomized control trial of parent-mediated treatment (N = 42, 12–30 months). Findings revealed that toddlers acquired skills following a reliable (vs. idiosyncratic) sequence and the majority of toddlers combined gestures with words before combining words in speech, but in contrast to the pattern observed in typical development, a significant subset acquired pointing after first words. 相似文献

Little is known about how children's value priorities develop over time. This study identifies children's value priority profiles and follows their development during middle childhood. Australian children (N = 609; ages 5–12 at Time 1) reported their values over 2 years. Latent Transition Analysis indicated four profiles: Social-Focus, Self-Focus, Growth-Focus and Undifferentiated. Within person development was characterized by profile stability or transfer to the Social-Focus profile. Younger children were more likely to have an Undifferentiated profile (or Self-Focus among boys) than older ones. Girls were more likely to have a Social-Focus profile or transfer to it, and less likely to have a Self- or Growth-Focus profile than boys. Social-Focus profile membership over time predicted more prosocial and less aggressive behavior. 相似文献

Acculturation consists of multiple domains (i.e., cultural practices, identifications, and values). However, less is known about how acculturation processes influence each other across multiple domains of acculturation. This study was designed to investigate transition patterns of acculturative processes within and across domains in a sample of 302 recent-immigrant Hispanic adolescents, Mage (SD) = 14.51 years (0.88) at baseline; male = 53%). Adolescents were assessed six times over a 3-year period. Latent profile analyses identified two profiles (high [or increasing] vs. low) for each domain at each timepoint. We found largely stable transition patterns in each domain over six timepoints. Importantly, sequential associations among profiles in acculturation domains were also detected. Implication for acculturation theory and research are discussed. 相似文献

abstractThis randomized controlled trial examined effects of the MyTeachingPartner-Math/Science intervention on the quality and quantity of teachers’ mathematics and science instruction, and children’s mathematics and science outcomes in 140 pre-kindergarten classrooms. Teachers participated in the intervention for two years with consecutive cohorts of children. Results from Year 1 are considered experimental, however due to high levels of attrition, results from Year 2 are considered quasi-experimental. Across both years, intervention teachers exhibited higher quality and quantity of instruction. In Year 1, there were no significant effects of the intervention on children’s outcomes. In Year 2, children in intervention classrooms made greater gains in teachers’ ratings of mathematics and science skills and performed better on a spring assessment of science skills. These results have implications for designing and evaluating professional development aimed at supporting children’s mathematics and science knowledge and skills. 相似文献

We examined two aspects of college students' (N = 385) sense of belonging and its relations with three indicators of self-regulated learning. We also tested the mediating role of achievement goals in these relations. One aspect, sense of belonging to school, functioned as a significant predictor of self-reported metacognitive and academic time management strategies. In comparison, a second aspect, sense of belonging to peer groups, was a significant predictor of self-reported peer learning strategies. Findings from the mediation analyses indicated that sense of belonging to school was related with mastery goals, whereas sense of belonging to peer groups was related with performance goals. Further, mastery goals mediated the relations between sense of belonging to school and metacognitive and academic time management strategies. 相似文献

Many educators in adult, community and higher education contexts are concerned with fostering reflective learning amongst their students. This paper explores the concept of critical reflection and considers how engaging with fiction may be an innovative pedagogical approach to support critical learning opportunities. Drawing upon interviews with fiction writers, ways in which critical reflection may be encouraged in connection to reading and writing fiction are taken up by exploring three different thematic areas that relate to a Habermasian framework of knowledge constitutive approaches to learning. These different areas can be categorised as (a) technical-rational, (b) humanistic and (c) critical or emancipatory. The first of these considers critical reflection as a way to develop technical capacities as a creative writer. The next section takes up a humanistic framework to explore the value of individual and collective learning opportunities to enhance personal growth and critical reflection. The third area of discussion considers a deeper critical or emancipatory framework of learning through critical reflection which may lead to social change. The paper concludes by considering the value of arts-informed adult education approaches, such as those related to fiction writing, to enhance the development of critical reflection amongst adult learners. 相似文献

Engineering education has been slow to adopt research-based educational innovations. Few prior works on such adoption have investigated the combined classroom experiences of instructors and students when such innovations are being implemented. Therefore, this work focuses on the lived experiences of an instructor and her students when adopting an active, blended, and collaborative learning environment, known as Freeform, in a second-year dynamics course. Weekly reflections from the instructor were processed alongside student interviews using Thematic Analysis to discern prominent themes in their perspectives for comparison and discussion. The results indicate that the instructor navigated internal tensions between her previous instructional preferences and the philosophy and resources of Freeform. Similarly, students had to adapt to this new philosophy and suite of resources that were uncommon for their institution. Ultimately, this work highlights the contextual natures of teaching and learning, and how situational factors can influence educational innovation. 相似文献

Teacher–student discourse continues to be teacher-centred even though researchers and reform documents have recommended changes toward increased levels of student-centred discourse. In science education this situation is paralleled by effort to make scientific inquiry more student-centred. The purpose of this study was to investigate how discourse forms changed over time in a classroom where the regular teacher and his students were scaffolded in the transitioning to student-centred scientific inquiry. Video-recordings were collected at intervals over one academic year. Three prominent forms of discourse were identified: two teacher-authoritative forms and one more interactive, dialogic form. As the lessons increasingly turned into student-centred scientific inquiry, a shift to the dialogic discourse form was found. Co-teaching provided for (a) guidance towards an organisation of events in the classroom that included regular teacher–student dialogue (b) modelling of the more dialogic form of discourse. 相似文献

‘Is it because I’m a woman?’ Gender-based attributional ambiguity in higher education administration
This study examines gender-based attributional ambiguity among higher education administrators in the US, specifically academic deans. Attributional ambiguity involves situations in which members of underrepresented groups cannot determine whether interactions both negative and positive have occurred because of their minority status or for some unrelated yet plausible reason. A conceptual model of attributional ambiguity in higher education administration is presented highlighting the types of situations that produce this ambiguity, two variants of attributional ambiguity (i.e. cognitive and social), and the psychological and organizational consequences of such ambiguity. Reasons that attributional ambiguity is inherent to higher education administration are examined including the fluidity of gender roles, the culture of academia, and leaders’ minimization of discriminatory experiences. Implications for professional practice are also presented such as the need for curricula, trainings, mentoring, and coaching that addresses attributional ambiguity and greater publicity related to women’s underrepresentation in leadership roles in higher education. 相似文献

This paper examines the values of the CHE principles of Connectivity, Humanness and Empathy as a guiding framework for maximizing the ethical and methodological advantages of semi-structured interview research practices. The authors draw from two separate educational studies and apply the CHE principles to analyse and evaluate the effectiveness of decision-making in facilitating sustainable relationships with the participants in each study. Findings highlight that dialogical relations with participants were evident in both studies, and identify significant junctures where decision-making and actions influenced effective rapport-building and respectful and reciprocal relationships with participants in the research. The CHE principles emerge as providing a robust framework for educational researchers to employ when auditing their decision-making prior to and during their engagement in qualitative interviews. 相似文献
