The development of science process skills in authentic contexts     

Wolff-Michael Roth  Anita Roychoudhury 《科学教学研究杂志》1993,30(2):127-152

Instructional strategies and curriculum sequences aimed at teaching process skills have received considerable attention in science education. On the other hand, the teaching of domain-independent, context-free skills has been subject to criticism on the ground that important aspects of cognitive activities are functions of meaningful contexts. The intent of this study was to examine the development of integrated process skills in the context of open-inquiry laboratory sessions. The data-collection approach was qualitative and included videotapes of laboratory sessions, laboratory reports of students, and the reflective journals kept by the two teachers involved in the study. Forty-eight students from the Grade 11 introductory physics course, 29 students from the Grade 12 physics course, and 60 students from the Grade 8 general science course from an all-boys private school participated in the study. An interpretive research methodology was adopted for construction of meaning from the data. Students worked in collaborative groups during all of the open-inquiry laboratory sessions. Findings from the study indicate that students develop higher-order process skills through nontraditional laboratory experiences that provided the students with freedom to perform experiments of personal relevance in authentic contexts. Students learned to (a) identify and define pertinent variables, (b) interpret, transform, and analyze data, (c) plan and design an experiment, and (d) formulate hypotheses. Findings of this study suggest that process skills need not be taught separately. Integrated process skills develop gradually and reach a high level of sophistication when experiments are performed in meaningful context.  相似文献   

Gender-inclusive science teaching: A feminist-constructivist approach     

Anita Roychoudhury  Debora J. Tippins  Sharon E. Nichols 《科学教学研究杂志》1995,32(9):897-924

The underrepresentation of women in science is an extensively studied yet persistent concern of our society. Researchers have identified numerous educational and social factors thought to be responsible for this underrepresentation (Kahle, 1990a; Kelly, 1987). One of the dominant explanations, used by many researchers for years to discuss gender differences in science and mathematics achievement as well as interest, has been the differences in the cognitive abilities of men and women. This explanation, however, has been discarded in recent years (Linn & Hyde, 1989; Linn 1990). On the basis of their meta-analyses of various studies. Linn and Hyde (1989) concluded that gender differences in cognitive skills have declined and those that remain are largely explained by experiential differences. Women may not have different cognitive abilities, but they may have a different way of learning rooted in their role in society. The epistemic differences between men and women stemming from their standpoint in life can help us understand their differential interaction with the nature of science, and hence their participation in the field. In the following section, we will briefly discuss the feminist critique of science and extend the implication to science education.  相似文献   

Native Mexican Parents’ Beliefs About Children’s Literacy and Language Development: A Mixed-Methods Study     

Jorge E. Gonzalez  Alain Bengochea  Laura Justice  Gloria Yeomans-Maldonado  Anita McCormick 《Early education and development》2019,30(2):259-279

Research Findings. This study examined Mexican caretaker roles, beliefs, and practices around their child’s language and literacy development. Twenty-six parents in three preschools representing three socioeconomic strata located in Querétaro City, México completed questionnaires and participated in focus groups. We used convergent parallel mixed methods to analyze and compare parent questionnaire quantitative data and qualitative focus group data with a grounded theory approach to identify focus group discussion themes. Four themes were emerged: (a) Goals and expectations regarding reading and socioemotional development, (b) Perceptions and beliefs about children’s oral and written language, (c) Caretaker’s perceived role in children’s language and literacy development, and (d) Home and community learning-related resources and practices. Findings highlighted that Mexican parents highly value supporting their children’s education both socioemotionally and through engagement in literacy routines—evidence of duality in the educacíón value among native Mexican families. These literacy routines were complementary and responsive to teacher classroom instruction. Practice or Policy. Understanding how Latino families instantiate literacy practices to respond to American schooling expectations may be a way to address home-school discontinuities that often reflect lack of familiarity with the U.S. educational system.  相似文献

Chemistry inside an epistemological community box! Discursive exclusions and inclusions in Swedish National tests in Chemistry     

Marie Ståhl  Anita Hussénius 《Cultural Studies of Science Education》2017,12(2):395-423

This study examined the Swedish national tests in chemistry for implicit and explicit values. The chemistry subject is understudied compared to biology and physics and students view chemistry as their least interesting science subject. The Swedish national science assessments aim to support equitable and fair evaluation of students, to concretize the goals in the chemistry syllabus and to increase student achievement. Discourse and multimodal analyses, based on feminist and critical didactic theories, were used to examine the test’s norms and values. The results revealed that the chemistry discourse presented in the tests showed a traditional view of science from the topics discussed (for example, oil and metal), in the way women, men and youth are portrayed, and how their science interests are highlighted or neglected. An elitist view of science emerges from the test, with distinct gender and age biases. Students could interpret these biases as a message that only “the right type” of person may come into the chemistry epistemological community, that is, into this special sociocultural group that harbours a common view about this knowledge. This perspective may have an impact on students’ achievement and thereby prevent support for an equitable and fair evaluation. Understanding the underlying evaluative meanings that come with science teaching is a question of democracy since it may affect students’ feelings of inclusion or exclusion. The norms and values harboured in the tests will also affect teaching since the teachers are given examples of how the goals in the syllabus can be concretized.  相似文献   

Infant emotional and cortisol responses to goal blockage   总被引：2，自引：0，他引：2  

Lewis M  Ramsay D 《Child development》2005,76(2):518-530

This study examined the relation of infant emotional responses of anger and sadness to cortisol response in 2 goal blockage situations. One goal blockage with 4-month-old infants (N = 56) involved a contingency learning procedure where infants' learned response was no longer effective in reinstating an event. The other goal blockage with 6-month-old infants (N = 84) involved the still face procedure where infants' reactions to their mothers' lack of responsivity were not effective in reestablishing interaction. For both blockages, sadness was related to cortisol response, though anger was not--the greater the sadness, the higher the cortisol response. This differential relation is consistent with other evidence indicating the more positive role of anger as opposed to sadness in overcoming an obstacle.  相似文献   

Reactivity and regulation in cortisol and behavioral responses to stress   总被引：4，自引：0，他引：4  

Ramsay D  Lewis M 《Child development》2003,74(2):456-464

This study examined relations between reactivity (i.e., peak response) and regulation (i.e., response dampening) in 6-month-old infants' cortisol and behavioral responses to inoculation (N = 62). Data showed that reactivity and regulation were unrelated for both cortisol and behavior. The independence of reactivity and regulation suggests that measures of both are needed to characterize infant cortisol or behavioral response to stress more completely. For both reactivity and regulation, cortisol and behavior were unrelated, suggesting that measures of both are needed to assess infant stress more adequately. There was considerable variation in the timing of the peak cortisol response, suggesting that obtaining only a single poststressor cortisol sample does not provide a sensitive measure of cortisol reactivity.  相似文献   

Child Care Subsidy and Program Quality Revisited     

Becky F. Antle  Andy Frey  Anita Barbee  Shannon Frey  Jennifer Grisham-Brown  Megan Cox 《Early education and development》2013,24(4):560-573

Research Findings: Previous research has documented conflicting results on the relationship between program quality and the percentage of children receiving subsidized child care (subsidy density) in early childhood centers. This research examined the relationship between subsidy density and the quality of infant and preschool classrooms in child care centers, taking into consideration teacher education and salary as well as other structural variables associated with quality. A multimethod evaluation was conducted with 110 child care centers utilizing an interview of center directors as well as classroom observations using standardized measures of quality and language/literacy in the classroom. Regression analyses indicate that subsidy density does not predict the quality of infant classrooms. However, subsidy density is a significant predictor of the quality of preschool classrooms. Teacher education is predictive of some quality indicators, but teacher salary is not. Practice or Policy: Practice and policy implications are discussed to promote the quality of child care centers that serve low- income children. Statewide initiatives should target centers with higher subsidy density for quality improvements. Local programs and state policy should provide teachers with opportunities to obtain additional education and then offer incentives to remain in their current early childhood settings.  相似文献
