The goal of this research was to highlight the role social regulatory processes play in making students’ teamwork in reciprocal teaching (RT) groups (a classroom activity in which students take the teacher’s role in small group reading sessions) effective. In addition to teamwork quality, we expected peer feedback to be a key factor in enhancing students’ reading comprehension achievements. Because previous research (Schünemann et al. in Contemp Educ Psychol 38:289–305, 2013) has shown that procedures of self-regulated learning (SRL) augment the effects of RT methods, we further assumed that such procedures would promote the quality of students’ collaborative efforts. In a cluster-randomized trial, students in 12 fifth-grade classes practiced a strategic approach to reading either in a RT condition or in a RT + SRL condition. In one of the 14 sessions, students’ interactive behavior was videotaped. Strategy use and reading comprehension were assessed at pretest, posttest, and maintenance. Performance differences between conditions were reliable only at maintenance. A multilevel mediation analysis showed that relative to RT students, RT + SRL students were better able to provide their teammates with informative feedback and organize their group work in a task-focused manner. Only feedback quality mediated the sustainability of treatment effects on strategy use and reading comprehension. In essence, this research suggests that effective reading comprehension trainings should integrate explicit instruction and practice in reading strategies, SRL, and focus on supportive peer processes in small groups with extensive instruction and practice in peer feedback. 相似文献

The media have a profound effect on the worldview of their consumers and should be carefully considered in matters of immigration. Often, migrants are portrayed through a negative lens by the media and most usually as a homogenous group rather than as individuals. This article examines the portrayal of migrants in one particular context (Germany) and questions what the best ways would be for handling these negative images, especially but not only in education systems. The author concludes that perhaps the combination of viewing migrants as individual people, rather than as a homogenous group, as well as more positive media portrayal of migrant people, would lead to a more positive representation of migrants in society. 相似文献

A major source of difficulties in promoting students’ understanding of genetics lies in the presentation of gene concepts
and models in an inconsistent and largely ahistorical manner, merely amalgamated in hybrid views, as if they constituted linear
developments, instead of being built for different purposes and employed in specific contexts. In this paper, we report the
results of a study about how textbooks can provide the grounds for the students’ construction of such hybrid views about genes.
These views are a key problem in genetics teaching, because they make it more difficult that students properly understand
this central biological concept and strengthen genetic deterministic ideas, which characterize a widespread discourse about
genes in the public opinion. We analyzed 18 textbooks using categorical content analysis, employing categories derived from
the literature addressing the historical development of gene models and concepts. Our findings indicate that the analyzed
textbooks do convey hybrid views about genes, with no correspondence to scientific models related to this biological concept.
These views reinforce genetic deterministic discourses and may lead students to serious misunderstandings about the nature
of genes and their role in living systems, with consequences to future learning about genetics. 相似文献

This is a report of a study of students’ understanding of infinite series. It has a three-fold purpose: to show that students may construct two essentially different notions of infinite series, to show that one of the constructions is particularly difficult for students, and to examine the way in which these two different constructions may be built so that we may uncover ways to help students improve their understanding. The theoretical framework consists of action–process–object–schema theory and the specific model of conceptions in Balacheff’s theory of conception, knowing, and concept. Approaching the problem from these two different theoretical perspectives allows us to provide different and at the same time complementary explanations of observed phenomena. The two different infinite series constructions are, briefly stated, series as an infinite unending process of addition and series as a sequence of partial sums. Students are found to have difficulty building an understanding of series as a sequence of partial sums and thus tend to have difficulty in problem situations that require this interpretation. The study uses semi-structured interviews with 10 graduate students. The interviews explore situations that might give insight into students’ notion of the sequence of partial sums. 相似文献

This study examined a moderated mediation model among 314 Black adolescents aged 13–18. The model included general coping strategies (e.g., active, distracting, avoidant, and support‐seeking strategies) as mediators and racial identity dimensions (racial centrality, private regard, public regard, minority, assimilationist, and humanist ideologies) as moderators of the relation between perceived racial discrimination and depressive symptoms. Moderated mediation examined if the relation between perceived racial discrimination and depressive symptoms varied by the mediators and moderators. Results revealed that avoidant coping strategies mediated the relation between perceptions of racial discrimination and depressive symptoms. The results indicated that avoidant coping strategies mediated the relation between perceived racial discrimination and depressive symptoms among youth with high levels of the minority/oppressive ideology. 相似文献

The aim of this paper is to investigate in a systematic and comparative way previous results of independent studies on the treatment of genes and gene function in high school textbooks from six different countries. We analyze how the conceptual variation within the scientific domain of Genetics regarding gene function models and gene concepts is transformed via the didactic transposition into school science textbooks. The results indicate that a common textbook discourse on genes and their function exist in textbooks from the different countries. The structure of science as represented by conceptual variation and the use of multiple models was present in all the textbooks. However, the existence of conceptual variation and multiple models is implicit in these textbooks, i.e., the phenomenon of conceptual variation and multiple models are not addressed explicitly, nor its consequences and, thus, it ends up introducing conceptual incoherence about the gene concept and its function within the textbooks. We conclude that within the found textbook-discourse ontological aspects of the academic disciplines of genetics and molecular biology were retained, but without their epistemological underpinnings; these are lost in the didactic transposition. These results are of interest since students might have problems reconstructing the correct scientific understanding from the transformed school science knowledge as depicted within the high school textbooks. Implications for textbook writing as well as teaching are discussed in the paper. 相似文献

A new phase of research on teaching is under way that seeks to understand the teaching brain. In this vein, this study investigated the cognitive processes employed by master teachers. Using an interview protocol influenced by microgenetic techniques, 23 master teachers used the Self‐in‐Relation‐to‐Teaching (SiR2T) tool to answer “What are you focusing your mind on throughout the process of teaching?” A number of emergent themes were identified in participants' responses and one, awareness of interaction, is discussed here. This theme refers to teachers' recognition of the learner–teacher (L‐T) relationship as a separate entity or system. Within interaction, at least three types of awarenesses emerged in teachers' responses: (1) connection, (2) collaboration, and (3) mutual effects. Furthermore, some teachers described a sense of synergy with their students due to this L‐T interaction. The results suggest that a teacher's awareness of interaction plays an important role in the teaching brain, and support the implications of the proposed teaching brain framework. 相似文献

The Dutch Pictorial Scale of Perceived Competence and Social Acceptance for Children with Cerebral Palsy was translated and administered to an English sample. This scale was developed to assess the child's perception on cognitive, physical and social domains. Thirty-two children, aged 4 to 9 years, were tested twice. The results indicate good test/retest reliability and good internal consistency. The results on the intercorrelations between the four sub-scales supported internal validity of the pictorial scale. It is concluded that the pictorial scale for young children with cerebral palsy is a reliable and valid instrument for determining the perception of children with cerebral palsy, and application in clinical and class settings is discussed. 相似文献
