Use of Contextual Information and Prediction by Struggling Adult Readers: Evidence From Reading Times and Event-Related Potentials

We employed self-paced reading and event-related potential measures to investigate how adults of varying literacy levels use sentence context information when reading. Community-dwelling participants read strongly and weakly constraining sentences that ended with expected or unexpected target words. Skilled readers showed N400s that were graded by the cloze probability of the targets, with larger N400s for more unexpected words. Moreover, it took these participants longer to read unexpected targets in strongly than weakly constraining sentences, suggesting a processing cost for revising predictions. Among less skilled readers, a reliable N400 difference was found between expected and unexpected targets only for the strongly constraining sentences. They also took longer when targets were unexpected, regardless of the context. These findings suggest that lower literacy readers could only immediately take advantage of strongly constraining context information to facilitate word processing and that they do not make as much use of predictive processing during comprehension.     

Distance learners’ multiple goals,learning and achievement in different learning situations

Can mastery and performance-approach goals predict distance learners’ learning and achievement in different learning situations over an academic year? Using a prospective longitudinal design, the current study examined this research question using a cohort of distance learners in Hong Kong. Two hundred and seventy-two distance learners completed three survey questionnaires at the beginning, in the middle and towards the end of an academic year. Regression analyses found that distance learners’ mastery and performance-approach goals at the beginning of the academic year predicted learning interest and the use of regulatory strategies in subsequent surveyed points after controlling for the effects of the age factor and self-efficacy levels.     

Educational reform in Singapore: from quantity to quality

In 2004, Prime Minister Lee called teachers to “teach less” so that students might “learn more”. In 2005, the Ministry of Education clarified this philosophical statement to mean transforming learning from quantity to quality—“more quality and less quantity” in education. This is in line with the national vision of ‘Thinking Schools, Learning Nation’. This policy initiative, which began in 2004, is set to change the fundamental nature of education in Singapore. This article discusses this initiative, its major implications for schools in Singapore and the challenges to be addressed in the implementation of the policy. In particular, the article discusses the issues of understanding an engaged learning paradigm, establishing signposts for the shift from quantity to quality and the difficulties of system-wide transformation. The challenge for schools is to go beyond the form of the initiative to bring real, substantial and sustainable educational change through this movement.     

Microfluidic on-chip fluorescence-activated interface control system

A microfluidic dynamic fluorescence-activated interface control system was developed for lab-on-a-chip applications. The system consists of a straight rectangular microchannel, a fluorescence excitation source, a detection sensor, a signal conversion circuit, and a high-voltage feedback system. Aqueous NaCl as conducting fluid and aqueous glycerol as nonconducting fluid were introduced to flow side by side into the straight rectangular microchannel. Fluorescent dye was added to the aqueous NaCl to work as a signal representing the interface position. Automatic control of the liquid interface was achieved by controlling the electroosmotic effect that exists only in the conducting fluid using a high-voltage feedback system. A LABVIEW program was developed to control the output of high-voltage power supply according the actual interface position, and then the interface position is modified as the output of high-voltage power supply. At last, the interface can be moved to the desired position automatically using this feedback system. The results show that the system presented in this paper can control an arbitrary interface location in real time. The effects of viscosity ratio, flow rates, and polarity of electric field were discussed. This technique can be extended to switch the sample flow and droplets automatically.     

Choice of Holland's Social Type College Majors for U.S. Racial/Ethnic Groups

We used national data to study the longitudinal effects of several variables on choice of Holland (1997) social type college majors versus other majors. We examined these effects for four of the five major U.S. racial/ethnic groups, Asian/Pacific Islanders, Hispanics, Blacks, and Whites. Effects of mathematics scores and gender on choice of social majors were fairly consistent across racial/ethnic groups, whereas effects of reading scores and SES differed across racial/ethnic groups. Results for Whites were most consistent with Holland's theoretical formulations regarding the effects of variables on choice of social-type educational/occupational environments.     

Health benefits of Kung Fu: a systematic review

The Chinese martial arts (Kung Fu) have existed for centuries and are generally accepted as being beneficial for health without much empirical data. The aim of this systematic review was to assess the health effects of "hard" Kung Fu styles by performing electronic and manual searches of the literature. The aspects of health and the Kung Fu style examined varied between most studies; in some cases, the martial art group consisted of practitioners of other martial art styles also. Of 2103 references identified, only nine papers were eligible and reviewed. All were observational studies, observing a range of health aspects possibly related to Kung Fu training or performance. Our findings suggest that there is no evidence that Kung Fu practice is associated with the prevention or treatment of any health condition. However, as a moderate- to high-intensity form of aerobic exercise, it may confer benefits similar to those attributed to other aerobic training modalities. However, this hypothesis remains to be tested in clinical trials. Physiological benefits (e.g., aerobic capacity and bone density) may be associated with long-term Kung Fu practice. Future research in this area should adopt experimental designs, clearly identifying eligibility criteria, testing and training protocols, and include health-related outcomes and documentation of adverse events, to advance knowledge in this field.

Scan and Learn: Quick Response Code Enabled Museum for Mobile Learning of Anatomy and Pathology

In the past, medical museums played a significant role in anatomy and pathology training. The attraction of medical museums has declined recently due to the emergence of information technology and innovative medical curricula. An innovative mobile learning platform has been developed using quick response (QR) codes for the museum specimens at the Lee Kong Chain School of Medicine, Singapore. High-quality images of the potted specimens were captured and combined into an album and a video using Adobe Acrobat Pro 9 and Windows Movie Maker, respectively. Subsequently, QR codes were generated linking to PDF documents with annotations, pathology, and clinical history concerning the specimens. Quick response codes were piloted in gastrointestinal teaching module for Year 2 medical students. Survey responses were obtained from students to verify the efficacy of QR as a learning tool. The majority of students either agreed or strongly agreed that it was easy to access the information about the specimen with QR codes (4.47 ± 0.84), while 96% of students agreed that they are able to correlate the specimen with the annotated images (4.56 ± 0.56). The majority of students (78%) agreed that QR codes are useful for their learning (4.22 ± 0.87), while 75% of students felt QR codes motivate them to visit Anatomy Resource Centre. Most of the students agreed that QR codes are useful for revision of materials (4.13 ± 1.07) and independent learning (4.38 ± 0.87). These findings suggest that QR codes are not only effective for students learning but also enhance their exploration experience with the museum specimens.
