Metacognition in Mathematical Problem Solving

Metacognition is considered by most educationists as an element necessary for many cognitive tasks. In problem solving, it has been said that possessing knowledge alone is insufficient and problem solvers need to exhibit high level cognitive skills like “self-regulation skills” (also known as metacognitive strategies) for successful problem solving.

A study on students' metacognitive strategies was carried out with over a thousand secondary and pre-university students from 12 schools. A questionnaire adapted from Biggs (1987) was administered to students at various levels (Secondary 2, Secondary 4, Pre-University 1), from different academic tracks (General, Science, Arts) and academic streams (Special, Express, and Normal). They were required to self-report on their metacognitive beliefs; their use of metacognitive strategies in mental tasks involving memory, problem solving and comprehension; and their attitudes towards the learning of various academic subjects. 20 items from the questionnaire which were related to problem solving were categorized into four stages, namely, orientation, organisation, execution and verification and data from these items were analysed.

Some findings that emerged were:

• (a) Normal stream students exhibited a lower usage of metacognitive strategies as compared to students from the Express and Special streams.

• (b) Metacognitive strategies used by Normal stream students tended to be of the “surface” type.

• (c) There was no significant difference in the frequency of usage of metacognitive strategies between students from different academic tracks.

• (d) During the problem solving process, students spent most time on evaluation of answers rather than on monitoring their understanding.

• (e) Students from different levels (Secondary 2, Secondary 4 and Pre-University) exhibited similar frequency of usage of metacognitive strategies in problem solving.

• The implications of these findings on future research and development projects as well as the teaching of metacognitive strategies are discussed in the paper.

     

Schematic interface of sound creation for computer animators

INTRODUCTION In the competitive field of animation, sound is an essential element for one to stand out from the others. With sound, we perceive a unique meaning from the frame. Imagine a simple bouncing ball scene—we can apply the sound of “a pingpong hitting on a table” or “a basketball hitting on a gymnasium floor”. It tells us a different narrative of the ball. Without sound, we lose an effective portrayal on its storytelling. Besides, sound also affects our perception of an anim…

Anik E2 Over the Prairies: inter‐organizational collaboration in the application of satellite technology

This paper describes the inter‐organizational collaboration which contributed to the development and satellite‐mediated delivery of university courses to a highly dispersed, rural population. This collaboration yielded results beyond what each group of stakeholders could have achieved on its own, but the project confirms the observation of some educators that collaboration, within the context of adopting innovative procedures, is a process fraught with potential pitfalls. There are, however, some practical strategies which can encourage the partners to work together towards a common goal.     

Reading comprehension,working memory and higher-level language skills in children with SLI and/or dyslexia

This study examined (1) whether working memory and higher-level languages skills—inferencing and comprehension monitoring—accounted for individual differences among Chinese children in Chinese reading comprehension, after controlling for age, Chinese word reading and oral language skills, and (2) whether children with specific language impairment (SLI) or dyslexia showed deficits in these skills. Eighty-two Cantonese Chinese-speaking children between the age of 7; 8–9; 5 were assessed. Regression analyses on the full sample offered support for the first question. The children were also classified into four groups: Typically-developing (TD; N = 34), specific language impairment-only (SLI-only; N = 18), SLI-dyslexia comorbid (SLI-D; N = 22) and dyslexia-only (D-only; N = 8). Pair-wise comparisons focusing on the second question revealed that both the SLI-only and the D-only group performed worse than the TD group in reading comprehension after controlling for age and nonverbal intelligence. The SLI-only and the D-only group showed a different profile of deficits: only the SLI-only group performed worse than the TD group in working memory, comprehension monitoring, and inferencing. The SLI-D comorbid group did worse than the SLI-only, but not the D-only group, in reading comprehension. The SLI-D comorbid group did not do worse than either single diagnosis group in the higher-level language skills associated with reading comprehension. These findings suggested adopting different intervention approaches for reading comprehension difficulties in children with SLI versus children with dyslexia.     

Fostering personalized learning in science inquiry supported by mobile technologies

In this paper, we present a mobile technology-assisted seamless learning process design where students were facilitated to develop their personalized and diversified understanding in a primary school??s science topic of the life cycles of various living things. A goal-based approach to experiential learning model was adopted as the pedagogical design to support the student??s personalized learning process. We chose to report the student??s inquiry into the life cycles of the spinach plant and the butterfly to pinpoint the how the student??s personalized learning was fostered in the experiential learning. The learning process consisted of (a) in-class enculturation and question posing; (b) out-of-class field trip observation; (c) on site reflection after observation; (c) data collection and conceptualization of life cycles in the field trip; (d) the hands-on experimentation of growing the spinach plant and rearing a butterfly after the trip at home; (e) creation of animations and composition based on the hands-on experience individually either at home or in class to re-conceptualize the life cycles of the spinach plant and the butterfly, and (f) sharing and evaluation of their work in class. Each student was assigned a smartphone on a 1:1, 24?×?7 basis, which was used by individuals to mediate their seamless learning experience across multiple contexts. Through our analysis of the learning content, processes and products, we illuminate how the goal-based approach applied to mobile-assisted experiential learning facilitates students?? personalized learning and helps them to fulfill their agency in such learning experiences.     

The unintended hegemonic effects of a limited concession: institutional incorporation of Chinese schools in post-war Hong Kong

Using the case of Chinese schools in post-Second World War Hong Kong, this paper explores the unintended consequences of an incomplete hegemonic project. After World War II, anti-imperialist pressures and rising educational demands in the local setting propelled the colonial authorities to be more active in providing and funding Chinese schools. This development created a considerable number of vernacular institutions that were either directly state-run or generously government-financed. Nevertheless, this concession was circumscribed because the regime eschewed universal and compulsory education, and many Chinese schools remained private and unaided. Producing three different types of vernacular institutions, the state’s partial incorporation of these institutions unwittingly divided these schools and pre-empted them from forming a united, antagonistic identity. These findings urge us to examine carefully, when using Gramsci’s concept of hegemony, the extent of compromise the powerful have actually conceded. They also hint that hegemony should not be conceived only as a conscious, conspiratorial project, for state practices occasioned by conjunctural forces may produce unintended consequences that have profound repercussions on political power.     

Reading motivation and reading comprehension in Chinese and English among bilingual students

One hundred four Hong Kong Chinese fifth graders completed a questionnaire on eight separate motivational subscales related to reading separately for Chinese as a first language (L1) and English as a foreign language (EFL) in addition to measures of both Chinese and English reading comprehension. Motivations related to self-efficacy, curiosity, involvement, recreation, and social-peer attitudes were significantly higher for L1 as compared to EFL reading. No difference across EFL and L1 was found for the motivational subscales in the areas of school grades, instrumentalism, and social-family attitudes. Furthermore, instrumentalism was particularly strongly correlated with EFL reading comprehension, whereas recreation had the highest association with L1 reading comprehension. The eight subscales collectively explained 16% variance in Chinese and 12% variance in English reading comprehension. Results underscore the importance of different types of motivation for reading comprehension and the different roles each motivational aspect may play in L1 and EFL reading.
