Help requests in tutoring at 30 months: Adaptation to the social situation     

Mina Verba  Haydée Marcos 《European Journal of Psychology of Education - EJPE》1998,13(3):309-322

This study lies at the crossroads between the study of tutoring interactions and the study of communicative skills in young children. Our goal was to show that in a tutor-novice problem solving situation, the frequency and the nature of the novice’s requests vary with the type of tutor. Three groups of twelve 30 months-old children (novices) were observed in interaction with a child tutor, their mother, and a female experimenter as they performed two assembly tasks. We examined the frequency, form, and content of the children’s requests for help, and their connection with some of the tutor’s actions. The main results showed that the children made more requests of adult tutors, and that direct forms were more frequent with the mother than with a child tutor. The results also indicated that these differences were not due to request-inducing or inhibiting actions on the part of the tutor. It is concluded that young novices are capable of adapting their help requests to the characteristics of their tutors.  相似文献   

What is the future of electrical impedance spectroscopy in flow cytometry?     

Furkan Gke  Paolo S. Ravaynia  Mario M. Modena  Andreas Hierlemann 《Biomicrofluidics》2021,15(6)

More than 20 years ago, electrical impedance spectroscopy (EIS) was proposed as a potential characterization method for flow cytometry. As the setup is comparably simple and the method is label-free, EIS has attracted considerable interest from the research community as a potential alternative to standard optical methods, such as fluorescence-activated cell sorting (FACS). However, until today, FACS remains by and large the laboratory standard with highly developed capabilities and broad use in research and clinical settings. Nevertheless, can EIS still provide a complement or alternative to FACS in specific applications? In this Perspective, we will give an overview of the current state of the art of EIS in terms of technologies and capabilities. We will then describe recent advances in EIS-based flow cytometry, compare the performance to that of FACS methods, and discuss potential prospects of EIS in flow cytometry.  相似文献   

Preservice teacher inquiry: Creating a space to dialogue about becoming a social justice educator     

Marvin Lynn  Renée Smith-Maddox 《Teaching and Teacher Education》2007

In this paper, we reflect on our experience with an experimental inquiry component within a teacher education program in a large urban city on the West Coast of the United States. This learning space, which is referred to as “Inquiry,” promotes the integration of theoretical and practical knowledge through reflection and dialogue. We highlight how this inquiry-oriented process enabled preservice teachers to reflect on and dialogue about existing ideals of social justice and equity with regard to teaching diverse learners. This process acknowledges that alternative learning spaces in teacher education programs that address ways of observing, questioning, and inventing may well be a valuable strategy in the development of social justice educators. While the process is a valuable one, we offer a critical analysis of our own processes. In particular, we discuss the need for the creation and implementation of strategies that help pre-service teachers build their capacity to teach in diverse urban classrooms.  相似文献   

Assessing the Impact of a Ceremony in Honor of the Body Donors in the Development of Ethical and Humanistic Attitudes among Medical Students     

Andrea Oxley da Rocha  Joao Lins Maués  Gabriel Antônio Flores Chies  Ana Paula da Silva 《Anatomical sciences education》2020,13(4):467-474

Activities related to body donation programs, such as donor memorial ceremonies, provide the opportunity to complement student training, especially with regard to the ethical and humanistic elements involved in medical training. This study sought to assess the impact of a ceremony in honor of the body donors has on ethical and humanistic attitudes in medical students. Medical students were surveyed about their perceptions of changes in themselves, respect for donors and donor families, and their relationship with patients. The effect of the students' contact with the family of the donor was analyzed in students who had contact with the cadaver in the dissection room and had either participated or not participated in the donor memorial ceremony. A total of 370 questionnaires were answered by first-, second-, and third-year medical students at the Federal University of Health Sciences of Porto Alegre in 2017. The students who participated in the ceremony presented more positive responses in relation to commitment to their studies, reflection on death, and positive development of empathy when compared to those who did not attend the ceremony. Most of the students that attended the ceremony suggested the event led to an improvement in the doctor–patient relationship. These results suggest that cadaver dissection with accompanied memorial ceremony involving contact with donor families is an effective means of fostering ethical and humanistic attitudes among medical students from the beginning of the course.  相似文献

Treating children's aggressive behavior problems using cognitive behavior therapy with virtual reality: A multicenter randomized controlled trial     

Sophie C. Alsem  Anouk van Dijk  Esmée E. Verhulp  Tycho J. Dekkers  Bram O. De Castro 《Child development》2023,94(6):e344-e361

This multicenter randomized controlled trial investigated whether interactive virtual reality enhanced effectiveness of Cognitive Behavioral Therapy (CBT) to reduce children's aggressive behavior problems. Boys with aggressive behavior problems (N = 115; M_age = 10.58, SD = 1.48; 95.7% born in Netherlands) were randomized into three groups: CBT with virtual reality, CBT with roleplays, or care-as-usual. Bayesian analyses showed that CBT with virtual reality more likely reduced aggressive behavior compared to care-as-usual for six of seven outcomes (ds 0.19–0.95), and compared to CBT with roleplays for four outcomes (ds 0.14–0.68). Moreover, compared to roleplays, virtual reality more likely enhanced children's emotional engagement, practice immersion, and treatment appreciation. Thus, virtual reality may be a promising tool to enhance CBT effectiveness for children with aggressive behavior problems.  相似文献   

Lessons from the famous 17th-century paradox of the Chevalier de Méré     

José Daniel López-Barrientos  Eliud Silva  Enrique Lemus-Rodríguez 《Teaching Statistics》2023,45(1):36-44

We take advantage of a combinatorial misconception and the famous paradox of the Chevalier de Méré to present the multiplication rule for independent events; the principle of inclusion and exclusion in the presence of disjoint events; the median of a discrete-type random variable, and a confidence interval for a large sample. Moreover, we pay tribute to our original bibliographic sources by providing two computational tools to facilitate the students' insights on these topics.  相似文献
