This paper emphasizes the productive aspect of morphological processingand the effect on spelling proficiency in 226 grades 4, 5 and 6 children. Two convergent studies using reaction time measures aimed at exploring ten- to twelve-year old spellers' sensitivity to, and knowledge of, derivational morphology with lexical items varying in orthographic and phonological transparency and opacity. There is some evidence, from the accurate and rapid vocal production of base forms or derived forms of source words in sentential contexts, that the depth of segmentation to base morphology and the converse process of derived morphology of words, plays a role in spelling performance of these children. There are complex orthographic, phonological and semantic factors affecting morphological processing. 相似文献
In this study, we investigated-secondary school students’ perceptions of their constructivist learning environment in Liberal Studies, and whether their perceptions were related to their critical thinking ability. A convenience sample of Secondary Three students (N = 967) studying Liberal Studies in Hong Kong participated in this research by completing a self-administered questionnaire which included the Constructivist Learning Environment Survey (CLES), Cornell Critical Thinking Test Level X, and demographic information on age and gender. Students perceived their learning environment to be moderately constructivist in nature. Both age and school banding differences were identified in that younger students and students in band 1 schools tended to perceive a higher degree of constructivist characteristics in their learning environment. Multiple regression analyses indicated that three of the five scales of CLES were predictors of critical thinking ability. Shared Control was the strongest predictor and negatively associated with critical thinking ability, while Personal Relevance and Critical Voice were positively related to critical thinking ability. Findings of the study are discussed with reference to developing students’ critical thinking ability in Liberal Studies classrooms. 相似文献
The kinematics of a badminton racket during a smash stroke was observed in this study with the purpose of investigating stroke
dynamics and racket behaviour. Motion capture measurements of the racket during several smash strokes performed by three players
of different skill levels indicated a clear increase in racket velocity at impact with increasing skill level. Variations
between translational and rotational contributions to the impact speed could also be seen between the players. The advanced
player produced a much higher peak angular velocity and also relied much less on translation, with a translational velocity
of only 8% of the total velocity versus the 20% for the recreational player. It is proposed that, as an alternative to shuttlecock
speeds, racket head speed measurements can be used as an indicator of performance, and can also provide some insight into
the interaction between the racket and player. 相似文献
The Questionnaire on Teacher Interaction (QTI) is a teacher–student relationship measure whose underlying two-dimensional structure is represented in a circumplex model with eight sectors. Using Smallest Space Analysis (SSA), this study examined the circumplex structure of the Chinese version of the QTI among a convenience sample of 731 primary-school students in Hong Kong. The study revealed that the SSA solution fits the circumplex structure of the Model for Interpersonal Teacher Behavior and uncovered a two-dimensional solution yielding five sectors in a clockwise direction: Strict, Leadership-Helpful/Friendly-Understanding, Student Responsibility/Freedom, Uncertain, and Admonishing-Dissatisfied. While the Leadership-Helpful/Friendly-Understanding sector was the largest, the Student Responsibility/Freedom sector was the smallest, with few items constituting it. For the two dimensions, the vertical dimension was named Structure Clarity, with adherence to external structure (Strict sector) at one extreme and lack of structure (Uncertain sector and Student Responsibility/Freedom sector) at the other extreme. The horizontal axis was labelled Attitude Valence, with benevolent valence (Leadership sector, Helpful/Friendly sector and Understanding sector) at one end and malevolent valence (Admonishing sector and Dissatisfied sector) at the other end of the axis. The positioning of the five sectors in the present study is in line with the factor structure that was often found in previous research on the circumplex model. By presenting a somewhat different interpretation of the two dimensions and some additional items, we hope that future research will verify our suggestions across different sociocultural settings. 相似文献
Two types of elementary mathematics word problems involving different linguistic structures were devised to examine the understanding
and solution of these problems by 91 Grade 3, 4, and 5 children divided into “more able” and “less able” subgroups. One task
consisted of 12 consistent and 12 inconsistent language problems on the basic processes of addition, subtraction, multiplication
and division. Another task consisted of a total of 36 word problems with 12 items each containing adequate, inadequate, and
redundant information, respectively, for problem solution. Subsidiary tasks of general ability, vocabulary, reading comprehension,
mathematics concepts, reflection on mathematics learning, and working memory were also administered to provide estimates of
the contribution of these “nonmathematics” tasks to the solution of elementary mathematics problems. Analyses of variance
and covariance of group data showed significant main effects of grade, consistency, and adequacy of linguistic information
in problem solution. Word problems containing inconsistent information were more difficult than those with consistent information.
Further, word problems containing inadequate and redundant information were more difficult to classify, and for the children
to explain, than those items with just enough information. Interviews with 12 individual children provided further insight
into their strategies for problem solutions. Both cognitive and developmental perspectives are important for mathematics learning
and teaching for children with or without learning disabilities. 相似文献
The more ambitious an educational innovation, the greater the challenge in scaling up. In this paper, we focus on the scaling up of an ambitious pedagogical practice—mathematics problem solving as a regular feature in the classroom. We adopt a long-term approach to continual professional development (CPD) that began with intensive work with one school before we broadened the programme to four other schools which span the spectrum of schools in Singapore. To evaluate this overall design, we examine the current state of each school’s capacity in sustaining mathematics problem-solving instruction. In particular, we study and report findings on these areas: the readiness of teachers, the instructional materials and supporting structures. Based on the findings, we reflect on our CPD strategies and our theory of action which guided the CPD programme.
AbstractThis exploratory study investigates the encounters and everyday experiences with the Facebook algorithm of 18 informants in Yangon, Myanmar. It draws on domestication theory and research on algorithms to understand how users come to use and respond to Facebook. Findings showed that their particular perception of Facebook algorithm—Friends funnel information—informs their domestication process, wherein they add strangers as Friends to draw more information flows to their News Feeds. 相似文献
Communication scholars have conflicting views on the relationship between exposure to science news and knowledge, and its subsequent influence on attitudes. Such mixed sentiments could arise from the vague definition of knowledge. Therefore, this paper explicates science knowledge into factual knowledge and subjective knowledge. It also compares the mediating roles of both types of knowledge between news attention and public support for science and technology (S&T). A survey of 967 Singaporeans showed that news attention was positively related to both factual and subjective knowledge. The findings revealed a stronger relationship between subjective knowledge and news attention than factual knowledge and news attention. Additionally, factual knowledge was positively related to public support for S&T, but subjective knowledge was negatively related to public support for S&T. The contrasting directions of these associations demonstrate that factual and subjective knowledge are two distinct dimensions of knowledge. Practically, the findings can inform policymakers and communication practitioners about effective public education and engagement initiatives. This study also provided guidelines for newsmakers in news reporting about S&T. 相似文献
