In Experiment 1, pigeons were trained in a within-subjects design to discriminate sequences of light flashes (illumination of the feeder) that varied in number, but not in time (2f/4sec and 8f/4sec), and in time, but not in number (4f/2sec and 4f/8sec). Number samples required a response to one of two comparison dimensions (either color or line), whereas time samples required a response to the remaining comparison dimension. Delay testing revealed a significant choose-small bias following number samples and a significant choose-long bias following time samples. In Experiment 2, testing confirmed that in the absence of a sample, there was a bias to respond small to the number comparisons and long to the time comparisons. Additional tests indicated that the birds were discriminating time samples on the basis of the number of light flashes occurring during the last few seconds of the time samples, rather than on the basis of the total duration of the flash sequence. Consequently, the choose-long bias observed for time samples during delay testing was really a choose-small bias. In Experiment 3, the birds received baseline training with a 5-sec delay and were subsequently tested at shorter and longer delays. A choose-large bias occurred at delays shorter than the baseline training delay, whereas a choose-small bias was again observed at delays longer than the baseline delay. These findings provide additional empirical support for the conceptualizing of memory for number and time in terms of a common mechanism.  相似文献

This article begins by reflecting on the present refugee crisis and its relevance to children in the UK. It identifies the need for teaching about the refugee experience to young children and argues that literature can provide a conduit for this. Since the millennium there has been a rapid increase in the number of books published for children which take this as their theme, aimed at ever-younger readers. Taking as a case study The Colour of Home by Mary Hoffman, a picturebook commonly used in lower primary classrooms, the article considers how this text promotes understanding and validates the circumstances of refugees. It closely examines the motivations and aims of the writer, how the book was mediated by teachers in the primary classroom, and how refugee and non-refugee children read and responded to it. Findings are presented from an interview with Mary Hoffman herself, juxtaposed with data from three classrooms suggesting that pupils gained valuable insight into a complicated and controversial issue. However the research concludes that viewing children through a refugee/non-refugee binary was reductive in not recognising the multi-layered nuances of meaning which were constructed by young readers who brought to bear a wide variety of individual life and family experiences. Furthermore, teachers in the study played a powerful role in mediating the texts when sharing them in the classroom, and devised a selection of stimulating resources to provoke reader response in terms of empathy, “social action”, and some critical literacy.  相似文献

Researchers and practitioners have become increasingly interested in how early childhood programs prepare young children for science. Due to a number of factors, including educators’ low self-efficacy for teaching science and lack of educational resources, many early childhood classrooms do not offer high-quality science experiences for young children. However, high-quality science education has the potential to lay an important foundation for children’s knowledge and interest in science as well as reinforcing and integrating critical language, literacy, and math readiness skills. This paper examines the current research on science in preschool classrooms and provides suggestions on how to teach science that supports children’s development across domains. Using the scientific method to explore science with young children provides a systematic model for engaging children in observation, questioning, predicting, experimenting, summarizing, and sharing results. These processes encourage children’s use of language, literacy, and mathematics skills in authentic ways. Suggestions are provided for teachers to use the scientific method as their guide for generating scientific discovery in their classroom.  相似文献

Background: Ghana has been the testing ground for many teaching and learning initiatives over the past 15–20 years. These initiatives, largely funded by donors, have sought to improve learning by introducing and reinforcing valuable teaching skills, materials and approaches, most of them child-friendly, learner-centred and involving activity-based learning (ABL). However, a problem in Ghana, also true of other countries in sub-Saharan Africa, is that whereas efforts over the past few decades have improved access to basic education in both pupil enrolment rates and teacher numbers, educational quality as measured by standardised test scores in key subject areas remains rather low.

Purpose: This article reports on an aspect of a DfID (Ghana) – sponsored research project which examined how the quality of teaching and learning in Ghanaian basic schools could be improved through the utilisation of ABL pedagogy. The current article examines three overarching themes relative to ABL pedagogy, namely how participants conceptualise ABL; ways in which ABL practices reveal themselves in classrooms; and challenges of ABL practices in Ghanaian schools.

Sample: Participants (comprising representatives of Colleges of Education, District Directors and frontline Deputy Directors of Education, headteachers and teachers) were drawn using purposive sampling technique from eight schools from within four districts of the northern region of Ghana.

Design and Methods: A case study approach was adopted for the study. Data collection took the form of semi-structured interviews, focused group discussions and observation of ABL practices and lessons in selected schools. Data analysis was undertaken using a ‘processual analytical approach’ with the view to catching realities of ABL practices in the Ghanaian educational setting.

Results: Our analysis reveals that whereas the literature on ABL emphasises multi-tasking and group work as essential ingredients of ABL pedagogy, the respondents conceptualised this as meaning pupils working on the same activity-related tasks at the same time in groups. Similarly, we found that, ideally, ABL practices reveal themselves through classroom practices such as display of pupils’ work in classrooms, organisation of the seating arrangements of pupils in groups, use of teaching and learning materials, formative assessment and activity-oriented lessons among others. However, in almost all the schools and classrooms we visited, these essential ingredients were missing owing to congestion and lack of furniture and logistics.

Conclusions: We conclude against the backdrop of our findings that ABL techniques can be utilised more effectively in Ghanaian schools if its practices are initially promoted in model schools, for lessons to be learned, and then scaled-up as expertise is established in these model schools.  相似文献

Motivation is a key factor in promoting academic success, and intrinsic motivation is especially important for developing autonomous learners. Reluctant learners, in particular, benefit from intrinsic motivation that makes learning relevant to their lives. In this article, the author describes commonalities of reluctant learners and presents definitions and frameworks for understanding motivation. The author also suggests a variety of strategies and activities for turning reluctant learners into inspired learners.  相似文献

Gatekeeping in counselor education is an ethical responsibility and professional best practice. The authors examined gatekeeping perceptions of 9 counselor educators, with equal representation of assistant professors, associate/full professors, and adjuncts/instructors/lecturers. The authors analyzed data using consensual qualitative research methodology (Hill, Thompson, & Williams, 1997 ). Findings include commonalities and differences between academic role groups.  相似文献
