Simians in the Shape School: A comparative study of executive attention

Executive functions (EF) have been studied extensively in children and adults. However, EF tasks for young children can be difficult to administer and interpret. Espy (1997, Developmental Neuropsychology, 13, 495–499) designed the Shape School task to measure inhibition and switching in preschool-aged children. Shape School presents cartoon-like characters that children must flexibly name by their color, their shape, or both, depending on cues that indicate the appropriate rule. Shape School has been found to be age sensitive as well as predictive of performance on other EF tasks. We presented a computerized analogue of Shape School to seven rhesus macaques. Monkeys were trained to categorize characters by color or shape, or to inhibit this response, depending on whether the characters had eyes open, eyes closed, or wore hats. Monkeys performed above chance on the inhibition and switching components of the task. Long runs of a single classification rule and long runs of noninhibition trials had no significant impact on performance when the rule changed or inhibition was required. This nonverbal adaptation of Shape School can measure EF in nonhuman animals and could be used in conjunction with other EF tasks to provide a clearer picture of both human and nonhuman executive functions.     

The credibility of online news: an evaluation of the information by university students / La credibilidad de las noticias en Internet: una evaluación de la información por estudiantes universitarios

Abstract

The spread of online disinformation is one of the 10 global risks of the future according to the World Economic Forum, and 51% of experts believe that this situation will not improve in the coming years. By 2022, half of the news will be fake news. In terms of users, young people and adults have problems understanding where the information they find online comes from and what sources to trust or not. In order to ascertain the degree of credibility that young users in Andalucía give to information, this study presents the results of the evaluation of online news by university students pursuing degrees in communication and education (N = 188), using the CRAAP test. The data reveal differences in gender and degree programme in the credibility assigned to the news. The conclusion is that university students have difficulty differentiating the veracity of the sources, in line with previous studies, with fake news earning higher ratings than real news.     

Activity Theory,Mediated Action and Literacy: Assessing how children make meaning in multiple modes

The paper reports a study into children's literacy in Bangladesh. It presents reading and writing profiles of a stratified random sample of ten year-old children. The paper argues that while these profiles might be a valuable source of information for the Government of Bangladesh as well as for the international donor community, especially in that they provide diagnostic information of children's literacy development, they do not portray fully the potential of children as meaning-makers. A small number of children from those who performed poorly in assessments of reading and writing were subjected to a further study in which they participated in a 'designing and making' activity. Here, the multiple modes through which children communicated meaning and understanding became the focus of the assessment. This means that we did not look solely at the linguistic mode but focused also on 'mediated action' as a mode through which meaning is made. Thus the potential of children to represent meaning and to create and shape 'new' texts through collaborative engagement with each other, as well as with the material and linguistic resources being used in the activity, became the prime focus of assessment. The paper shows that children who performed poorly on tests of reading and writing were potentially creative meaning-makers when other modes of representation like action and speech were considered. The paper concludes that large-scale studies of children's literacy are necessary and will continue to provide important sources of information for governments attempting to alleviate poverty and create equitable access to education and other social services. On the other hand, data obtained in this fashion mask the potential of children as creative meaning-makers. The study reported here shows that teacher-based assessment, expanded to recognise modes of meaning-making other than language, can be a vital, additional source of information for those interested in children as learners.     

俚语和成语,让你走出英语学习的黑暗

[接上期]Is Slang Only Used By The Lower Classes?“Absolutely not!”Itellmy internationalstudents. There is universal slang that is used by everyone. However, there are many subcategories of slang used by specific groups. Slang can be seen as a family tree with universal slang at the top representing words that are not only used consistently in the media, but by virtually everyone.     

Boxing clever: using shoeboxes to support home–school knowledge exchange

A key tenet of the Home–School Knowledge Exchange Project is that children's learning will be enhanced if the knowledge and experience that are to be found both at home and in school can be brought together. In this paper we explore ways of connecting home and school to support literacy learning at Key Stage 1, focusing on the home‐to‐school direction. We discuss how shoeboxes, filled with children's artefacts, can support a range of literacy‐related activities in school. It is suggested that the extensive diversity of knowledge and interests reflected in the chosen objects presents teachers with an invaluable opportunity to personalise children's literacy learning.     

Conceptual difficulties experienced by senior high school students of electrochemistry: Electrochemical (galvanic) and electrolytic cells

This research investigated students' understanding of electrochemistry following a 7–9-week course of instruction. A list of conceptual and propositional knowledge statements was formulated, and this provided the framework for semistructured interviews that were conducted with 32 students in their final year of high school chemistry, following instruction in electrochemistry. Three misconceptions identified in this study and five which have been reported earlier are incorporated into an alternative framework about electric current. The framework is grounded on the notion that a current always involves drifting electrons, even in solution. Another area where students' misconceptions were prevalent was in relation to the sign of the anode and cathode. Students who thought the anode was negatively charged believed cations would move toward it, and those who thought it was positively charged were unable to explain why electrons move away from it. Electrolytic cells also proved troublesome for students. Many students did not associate the positions of the anode and cathode with the polarity of the applied electromotive force (e.m.f.). Other students attempted to reverse features of electrochemical cells and apply the reversals to electrolytic cells. The implications of the research relate to students' interpretation of the language that is used to describe scientific phenomena and the tendency for students to overgeneralize, due to comments made by teachers or statements in textbooks.     

School district enrollment and inequality in the supply of classes

This study explores relationships between school district enrollment and the internal allocation of resources across subject areas of the curriculum. The central argument is that differences in how resources are allocated stem, in part, from the uneven impact district size has on the relative costs of educational services. These internal differences in resource allocation are viewed as a possible obstacle to achieving equity in the provision of educational opportunities. The empirical work is based on a random sample of New York State school districts and includes cross-sectional as well as longitudinal results.     

How children living in poor areas of Dar Es Salaam,Tanzania perceive their own multiple intelligences

This study was carried out with 1,857 poor children from 17 schools, living in low-income areas of Dar Es Salaam, Tanzania. All children took the ‘Student Multiple Intelligences Profile’ (SMIP) questionnaire as part of a bigger project that gathered data around concepts and beliefs of talent. This paper sets out two aims, first to investigate the structural representation of the self perceived multiple intelligences for this set of children and second to discuss how the best fit model might reflect children’s culture and their school experiences. After carrying out exploratory factor analysis, a four factor first order model was shown to have a good fit. A higher order factor solution was investigated owing to the correlation of two latent constructs. In order to provide some insight into the multiple intelligences construct the relationship between the SMIP items, student test outcomes and attitudes to learning were examined. The item groupings were explored through African cultural beliefs around intelligences indigenous to African communities.
