Children's stroke sequence errors in writing Chinese characters

Each Chinese character is a two dimensional logograph and if character writing is seen as drawing a diagram, then there is no obvious correct sequence in the writing process. However, over the ages and to this day, Chinese children have been taught the proper stroke sequence for forming the characters based on some calligraphic rules when they begin to learn to write in Chinese. The rationale for the teaching of stroke sequence has traditionally been argued on the basis of facilitating better calligraphy and as a memory aid for the exact reproduction of the correct form of the character. This paper reports on a study that tries to determine how far young children can master the correct stroke sequences in writing and the common kinds of errors children made. It further explores the importance of and the possible educational implications for the teaching of stroke sequences in the teaching of handwriting based on the empirical results.     

Development of the metalanguage and the acquisition of literacy: A progress report

In this paper we examine the relation between literacy, broadly conceived, and children's understanding of a set of concepts for representing language and meaning, primarily the concepts of what a text says as opposed to the interpretations one may make of that text. We refer to these concepts as the say/mean distinction. A series of studies are reported on children's developing understanding of this distinction and its implications for their progress in reading and interpreting texts. These studies indicate that while such interpretive distinctions are indeed important and while they are related to literate competence generally, it is a mistake to assume that they are strictly associated with the practices of learning to read and write. Far from being identified with reading and writing skills, these concepts appear to be a part of the general orientation to language and to forms of thought that are of particular relevance to a literate society. Consequently, they are acquired as much from the oral practices of literate parents as from the actual activities of reading and writing.This project was funded jointly by SSHRC and the Ontario Ministry of Education under its Block Transfer Grant to OISE.     

Social responsiveness and physical space as determinants of agonistic behavior inBetta splendens

Two experiments examined the conditions under whichBetta agonistic responding occurs by manipulating physical space and the species and social responsiveness of an opponent. In Experiment 1, both the species (conspecific or nonconspecific) and the aggressiveness (aggressive or nonaggressive) of the opponent were manipulated. The results indicated that agonistic behavior was greater with both conspecifics and aggressive opponents. Experiment 2 examined the effects of physical space and social responsiveness of the opponent on intraspecific aggressive behavior. An inverse relationship was found between physical space and the number of attacks directed toward the opponent. The results of both experiments also indicated thatBetta tend to attack aggressive opponents more than nonaggressive ones. It is suggested thatBetta aggress either when the individual animal is threatened or when physical space is limited.     

Habituation to illness: Effects of prior experience with the US on the formation of learned taste aversions in rats

Experiment 1 investigated the effects of US habituation on the acquisition and extinction of learned taste aversions in rats. Subjects receiving five noncontingent LiCl intubations prior to conditioning failed to develop a conditioned taste aversion, while control subjects experiencing a single saccharin/LiCl pairing displayed a pronounced taste aversion which weakened during subsequent poisonings. Experiment 2 examined whether habituation, defined as a waning of responses to repeated presentation of an illness stimulus, was a possible mechanism for explaining the results of Experiment 1. Subjects showed a decrease in motor activity following an initial LiCl intubation, but less attenuation of activity with successive intubations.     

Trends in research on project-based science and technology teaching and learning at K–12 levels: a systematic review

Project-based teaching is nothing new; it originates from the work of authors like Dewey and Kilpatrick. Recent decades have seen renewed interest in this approach. In many countries, it is currently considered to be an innovative approach to science and technology (S&;T) teaching. In this article, we present a systematic review of what recent scientific publications teach us about this approach: How is this approach identified in these publications? How is the use of this approach in school S&;T justified? What are the main research questions covered by studies in the field? What do these studies on this approach teach us? To answer these questions, we have selected and analysed articles published, between 2000 and 2014, in journals that are specialised in school science and technology education and that are indexed in ERIC database. In the synthesis based on this analysis, we present: (a) the theoretical constructs used by the authors to refer to this approach and the features identified to define it; (b) the justifications for this approach; (c) the research questions covered by studies in the field; (d) the data collection and analysis methods used in these studies; and (e) the main findings. In addition to presenting a synthesis of current research in this field, we offer a critical discussion thereof with a focus on two aspects, namely the way PBSTL is conceptualised and the rigour of the research methods used to ensure the validity of findings.     

Networking projects around the United States

Summary Networks are gaining popularity in the education community. The technology of networking offers many benefits for educators and students. The process of setting up and administering a network is determined by the needs and budget of the users. There are many hardware and software vendors who offer an array of products for designing, installing and maintaining networks. In some cases, schools have formed partnerships with businesses to provide networking services on the local, state, national and global levels. Educational networks will continue to proliferate throughout this decade, providing a new environment to help with word processing, database management, research, individualized instruction, parent education, professional development, and the many other concerns confronting schools today.     

Conflict, Understanding, and Relationships: Developments and Differences in the Preschool Years

Children's conflict management in three close relationships was studied longitudinally in 38 second born children, observed at home with their mothers and siblings at 33 months and at 47 months, and with friends at 47 months. Children used significantly more other-oriented argument with friends than with their mothers or siblings. Their use of reasoned argument with their siblings, but not their mothers, was related to their emotional understanding assessed formally at 40 months. The emotional context of conflict interactions was found to be important as an influence on children's use of reasoned argument, with less reasoning shown by children when they were upset at 33 months. The differences in patterns over time and in links with emotional understanding for these different relationships is discussed, and the significance of child-child interaction in the development of social understanding is highlighted.     

Evidence and Warrants for Belief in a College Astronomy Course

Science educators have argued that it is insufficient to be able to recite thetheories of science and not know how knowledge claims in science are justified, what counts as evidence, or how theory and evidence interact. We wonder, however, how much students' understandings of the nature of science vary with content. This paper draws on data collected in a university astronomy course. Data include three interviews and written work from twenty students, as well as written work from the 340 students in the class. This study provides us with evidence on how students' talk and writing about the nature of science differs depending on the particular scientific topic which is under discussion. The relationship between theory and evidence, warrants for belief, and nature of observation are described in various ways in the different disciplines discussed in the course.     

Stimulating transition to postconventional morality: The pickering high school study

Over a four-month period, a class of Grade 11 students were involved in discussion of ethical problems and principles at a postconventional level (as defined by Lawrence Kohlberg). At the beginning and the end of the period, these students used very little postconventional thinking. However, one year later they exhibited a significant usage of post-conventional moral thinking, in comparison with a control group that remained unchanged throughout.

Résumé Pendant quatre mois, les élèves d'une classe de onzième année ont participé à la discussion de problèmes et de principes de moralité au niveau post-classique (selon la définition de Lawrence Kohlberg). Au début et à la fin de cette période, ces étudiants ont exprimé peu de réflexions post-classiques. Un an plus tard, cependant, ils manifestaient une nette attitude fondée sur des principes de morale post-classique alors que l'attitude d'un groupe-témoin n'avait subi aucune modification pendant la même période.
