The operation of grade retention and educational inequality: who gets retained in Macao and why?

While the existence of a class, gender, or ethnic gap in educational attainment is well documented for many societies, how the practice of grade retention contributes to these patterns of educational inequality has been inadequately addressed. Given that grade retention is commonly practised in Macao, Macao is used as a case for illustration. Using data from PISA 2009 and a qualitative research project, we seek to demonstrate how inadequate state regulation could make possible the manipulation of grade retention institutionally and individually in Macao. This, in turn, illustrates how the specific contextualized structural operation of grade retention could serve as a mechanism for social differentiation and thus play a role in contributing to the observed educational inequality.     

Relationships between reading comprehension and its components in young Chinese-as-a-second-language learners

Based on the Simple View of Reading model, this study examines the relationships among Chinese reading comprehension and its two componential processes, Chinese character reading and listening comprehension, in young learners of Chinese as a second language (CSL) using a longitudinal design. Using relevant measures, a sample of 142 senior primary ethnic minority students in Hong Kong was assessed twice a year. The results of regression analyses showed that character reading and listening comprehension could together account for a significant portion of the variance in reading comprehension at grades 4 and 5 both concurrently and predictively. Subsequently, a trivariate, cross-lagged path model was specified to evaluate the relationships among these variables after controlling for their autoregressive effects. The study identifies statistically significant and unique contributions of character reading and listening comprehension to reading comprehension; further, it finds reciprocal relationships between reading comprehension and its componential processes. Moreover, the two componential processes themselves are significantly related across grades 4 and 5. Apart from supporting the predictive influence of character reading and listening comprehension on reading comprehension, the findings of this study reveal how Chinese language comprehension and literacy development are interrelated in young CSL learners.     

Patterns of participation in year 9 academic testing and factors predicting absence on the day of test

Policies aiming to improve educational outcomes are typically based on academic testing data. However, such data only reflect the performance of students who completed the tests. It is possible that students who were absent have shared characteristics. The proportion of students absent out of all eligible school students and whether they have shared characteristics has not been investigated, as this is only possible through the use of linked administrative data. Participants were born in Western Australia in 1994 and 1995, and their birth records were linked to participation status in the Year 9 academic tests to determine the proportion of students who were absent. Logistic regression was conducted to investigate characteristics which predicted absence on test day. A proportion of non-Aboriginal (3.2 %) and Aboriginal students (21.9 %) were absent on test day. Risk factors which predicted the absence included contact with Child Protection and Family Services, history of maternal mental health problems, and fathers aged below 20 years at the time of their child’s birth. A significant proportion of students was absent and therefore not represented in academic achievement information. These students were more likely to have experienced adverse events and therefore are not randomly absent. As these data are typically used to inform policies which aim to improve educational outcomes, they may lack the necessary information to adequately address the complex needs of students who are absent on test day. However, findings suggest that service providers, as well as schools may play an important role in encouraging participation in school.     

Development of an instrument for assessing senior high school students’ preferred and perceived laboratory classroom environment

This study aimed to develop an instrument, named the inquiry-based laboratory classroom environment instrument (ILEI), for assessing senior high-school science students’ preferred and perceived laboratory environment. A total of 262 second-year students, from a senior-high school in Taiwan, were recruited for this study. Four stages were included in the development of the ILEI: (1) item formulation, (2) content validation, (3) construct validation and (4) reliability calculation. The study revealed that the ILEI was valid and reliable. Most students showed a preference for a student-directed and teacher-guided hybrid learning environment. The development of the ILEI is likely to help researchers and teachers to more effectively understand student views of the laboratory classroom environment. Our profound hope is to utilise ILEI to improve teachers’ assessment and students’ learning in inquiry-based laboratory classroom environments.     

Blocking between landmarks during 2-D (touchscreen) and 3-D (ARENA) search tasks with pigeons

Many studies investigating cue competition have focused on the blocking effect. We investigated the blocking effect with pigeons using a landmark-based spatial search task in both a touchscreen preparation (Exp. 1a) and an automated remote environmental navigation apparatus (Exp. 1b). In Phase 1, two landmarks (LMs: A and Z) appeared on separate trials as colored circles among a row of eight (touchscreen) or six (ARENA) identical response units. Subjects were rewarded for pecking at a target response unit to the right of LM A and to the left of an extraneous LM, Z. During the blocking trials in Phase 2, LM X was presented in compound with a second LM (A) that had been previously trained. On control trials, LM Y was presented in compound with LM B and a target in the same manner as in the trials of AX, except that neither landmark had previously been trained with the target. All subjects were then tested with separate trials of A, X, B, and Y. Testing revealed poor spatial control by X relative to A and Y. We report the first evidence for a spatial-blocking effect in pigeons and additional support for associative effects (e.g., blocking) occurring under similar conditions (e.g., training sessions, spatial relationships, etc.) in 3-D and 2-D search tasks.     

Memory for everyday information in students with learning disabilities

This study compared students with and without learning disabilities (LD) on their recall of academic information and information encountered in the students' everyday lives. The academic recall measures included a sentence listening span test, a rhyming words working memory test, and a visual matrix working memory task. Students' cued recall of all the tasks was also measured. The everyday working memory tasks included a dance episode event recall test; a library procedure recall test; and recall tests of commonly found objects, such as a coin, a telephone, and a McDonald's sign. Compared to students without LD, students with LD performed poorly on both the academic recall tasks and the everyday recall tasks. These results support the notion that some students with LD may have working memory problems that affect their performance on tasks other than reading. The results of the cued recall showed that the availability of cues significantly decreased the ability group differences on many of the academic and everyday tasks. This result replicates prior research findings that students with LD do not use retrieval strategies effectively and that some students with LD may have a production deficiency that affects their retrieval of previously encoded information.     

Injury rates in professional soccer players during Ramadan

Many of the socio-cultural lifestyle and dietary changes that take place during Ramadan may affect the risk of injury in athletes, but little evidence is available. The aim of the present study was to examine the effects over two consecutive years of the holy month of Ramadan on injury rates in 42 professional players of a Tunisian top-level professional soccer team. Players were retrospectively organized into fasting and non-fasting groups and monitored for 3 months: 4 weeks before Ramadan, during the month of Ramadan (4 weeks), and 4 weeks after Ramadan each year. During Ramadan, training started at 22.00 h. The circumstances (training/match) and mechanism of injury (traumatic/overuse) were recorded. No significant differences between the three periods were observed for weekly mean training load, training strain, training duration, and Hooper's Index (quality of sleep, and quantities of stress, delayed-onset muscle soreness, and fatigue). Compared with non-fasting players, fasters had a lower (P < 0.05) Hooper's Index and stress during and after Ramadan. No significant difference in injury rates was observed between fasting and non-fasting players. Nevertheless, the rates of non-contact (6.8 vs. 0.6 and 1.1) and training overuse (5.6 vs. 0.6 and 0.5) injuries were significantly higher in fasting players during the month of Ramadan than before or after Ramadan. In conclusion, Ramadan, along with the corresponding changes in nutritional habits, sleeping schedule, and socio-cultural and religious events, significantly increased overuse and non-contact injuries in fasting players despite the fact that the training load, strain, and duration were maintained.     

Growth behavior of publications and patents: A comparative study on selected Asian economies

This study attempts to model the growth behavior of the number of publications and patents of South Korea, Taiwan, Japan and Malaysia. Three competing growth functions, namely, simple logistic growth function, bi-logistic growth function and logistic function within a dynamic carrying capacity were considered. The findings provide insight to the diffusion process of science and technology, often measured by the number of publications and patents, respectively. The function that provides the best fit to the observed data was opted for explaining the diffusion process. The function with the best fit is the bi-logistic growth function for the number of publications as well as the number of patents of South Korea and Taiwan, the logistic growth function within a dynamic carrying capacity (LGDCC) for the number of publications and the bi-logistic growth function for the number of patents of Japan, and the LGDCC for the number of publications and simple growth function for the number of patents of Malaysia. The results suggest a dynamic self-propagating growth for the science and technology, and thereby a transition from science and technology-push to market-pull growth for South Korea and Taiwan. While a similar transition was observed for the technology of Japan, the growth in science had entered a maturity stage. On the other hand, the growth potential in science is dynamic for Malaysia, but its technological advancement is relatively lower and static compared to the other economies.
