Reflection on the education policy orientation in post-May 31 reform in Korea

For the last 70 years, since the establishment of the Republic of Korea, Korean education has achieved universal expansion of educational opportunity from elementary to secondary to higher education. Planning, centralized policy making, top-down implementation, and administrative control had been the standards of the first few decades of Korean education. The so-called May 31 education reform implemented in 1995 made a turning point for these approaches to education policy and administration by highlighting autonomy, openness, diversity, accountability, consumer centeredness, market control, and governance for quality education. However, these government-driven education reform initiatives have resulted in limiting the expected outcomes. In this paper, the authors call for a new approach to education policy and administration and propose supporting school innovation, empowering an internal accountability system in governance. The authors also suggest a search for normative values for democratic communitarianism as a new philosophical foundation of education policy framework, beyond instrumental values of education.     

Hierarchical planning for a surface mounting machine placement

For a surface mounting machine(SMM)in printed circuit board(PCB)assembly line,there are four problems,e.g. CAD data conversion,nozzle selection,feeder assignment and placement sequence determination. A hierarchical planning for them to maximize the throughput rate of an SMM is presented here. To minimize set-up time,a CAD data conversion system was first applied that could automatically generate the data for machine placement from CAD design data files. Then an effective nozzle selection approach was implemented to minimize the time of nozzle changing. And then,to minimize picking time,an algorithm for feeder assignment was used to make picking multiple components simultaneously as much as possible. Finally,in order to shorten pick-and-place time,a heuristic algorithm was used to determine optimal component placement sequence according to the decided feeder positions. Experiments were conducted on a four head SMM.The experimental results were used to analyse the assembly line performance.     

Teachers’ Discussions Of Students’ Thinking: Meeting The Challenge Of Attending To Students’ Thinking

The purpose of this article is to describe findings from a study of teachers’ social interaction during discussions about students’ thinking. The goal of the discussions was for the teachers to interpret their students’ thinking as revealed from work on non-routine, thought-revealing mathematical tasks, known as model-eliciting activities. The research reported in this article focuses on instances during the discussions when the teachers engaged in what the researcher termed ‘mini-inquiries’, occasions during which the teachers inquired into why their students thought about the associated model-eliciting activities as they did or when the teachers inquired into the underlying mathematical complexities associated with the model-eliciting activities. During these mini-inquiries, the teachers typically engaged in one of four types of interaction patterns that enabled them to meet some of the challenges of attending to students’ thinking that are described in United States reform documents.     

Purification and relationship with gastric disease of a 130 kDa (CagA) protein of<Emphasis Type="Italic">Helicobacter pylori</Emphasis>

Objective: The aims of this research were to purify and identify the 130 kDa (CagA) protein ofH. pylori clinical isolate HP97002 and evaluate the relationships between the purified 130 kDa (CagA) protein and gastric diseases. Methods: The procedure for isolating the protein included 6 mol/L guanidine extract, size exclusion chromatography and elusion from gel. Sera of 68 patients with gastric diseases (44 with chronic gastritis, 15 with atrophic gastritis, 7 with peptic ulcer disease, 2 with gastric cancer) were obtained, and the serological response to CagA was studied by Western-blot using the purified protein. Results: The purified protein was 130 kDa and preserved good antigenicity and revealed basic isoelectric point about of 8.1. Among 68 sera, 43 sera could recognize the purified protein associated with chronic gastritis 47.7% (21/44), atrophic gastritis 86.7% (13/15), peptic ulcer disease 100% (7/7), gastric cancer 100% (2/2). Compared with each other, the difference was significant (χ²=13.327,P=0.004), and 130 kDa (CagA) protein was associated with severe gastric diseases (r _s=0.442,P=0.001). Conclusion: The 130 kDa (CagA) protein was associated with severe gastric diseases. Project supported by the China Medical Board (96-628) and Zhejiang Province Hygiene Bureau (2000 A055)     

Human causality judgments and response rates on DRL and DRH schedules of reinforcement

The effect of various relationships between a response (an investment made in the context of a game) and an outcome (a return on the investment) on judgments of the causal effectiveness of the response was examined. In Experiment 1, response rates and causal judgments were higher for a differential-reinforcement-of-high-rate (DRH) schedule relative to a variable-ratio (VR) schedule with the same probability of outcome following a response. Response rates were also higher for a DRH than for a variable-interval schedule matched for reinforcement rate. In Experiment 2, response rates and causal judgments were lower for a differential-reinforcement-of-low-rate schedule relative to a VR schedule with the same probability of outcome following a response. These results corroborate the view that schedules are a determinant of both response rates and causal judgments, and that few current theories of causal judgment explicitly predict this pattern of results.     

Development of auditory event-related potentials in young children and relations to word-level reading abilities at age 8 years

A relationship between brain responses at birth and later emerging language and reading skills have been shown, but questions remain whether changes in brain responses after birth continue to predict the mastery of language-related skills such as reading development. To determine whether developmental changes in the brain-based perceptual skills are systematically related to differences in word-level reading proficiency at age 8 years, brain event-related potentials (ERPs) to speech and nonspeech stimuli were recorded annually at the ages of 1 through 8 years in a sample of 109 typically developing children. Two measures of word-level reading (one that requires decoding of real words and one of pseudowords) were administered at age 8 years. Growth curve analysis, using the hierarchical linear models, related reading performance (average versus low) to the longitudinal maturation in the ERP waveform peak and latencies. Maturational changes (e.g., slope, acceleration, and cubic growth) in N1 amplitude from ages 1 to 4 were related to proficiency in decoding pseudoword stimuli only, with children who were less proficient in decoding pseudowords evidencing more steeply negative declines in amplitude with age, particularly at the frontal and parietal recording sites in response to both speech and nonspeech stimuli. In contrast, proficiency in decoding real words was related to developmental changes in N2 amplitudes from ages 4 to 8 only at the parietal recording site, and only in response to nonspeech stimuli. The early development of biologically based differences in the perception and processing of auditory information contributes to later group differences in reading proficiencies at school age.     

Educational Practice in Leadership Mentoring: The Singapore Experience

Findings of a study on the practice of school management learned through mentoring reveal that leading surfaced prominently as the prime aspect of what could be learned through formal mentoring and could be put into practice on the job. These principals, who have the opportunity to learn through mentoring, suggest their learning and practice of leading primarily through relating with people. The three features involved are: leading through relating with people actively, promoting trust in relating with people, and serving as worthy models in their dedication to service. As such, the learning of leading through formal mentoring could be of significance in the professional development of aspiring principals. It highlights a known practice of leading, learned through leadership mentoring, for an unknown future.

What Can Clients Tell Us about Seeking Counselling and Their Experience of It?

Research on counselling is often unknown to or ignored by counsellors. Research that explores counselling from the client’s perspective is even less familiar to most counsellors, perhaps because there is far less of it compared to the quantity of research investigating the process from the counsellor’s point of view. Nevertheless, research presenting the client’s perspective can be a useful guide to both counsellors and their clients. With this aim in mind, this article summarises some of the research that has been conducted from the client’s point of view and suggests implications for counselling practice.     

中小学几何教学之我见

中小学几何课程应当教些什么一直是个具有争议的课题.回顾欧氏几何的发展历史有助于我们对几何有更深入的理解.新加坡中小学几何课程受到“新数学”及“回归基础”等各种思潮的影响,新的数学大纲计划在2007年正式推出,在几何教学上也会有相应的变动.对于中小学几何课程应当教授哪些内容我们至今仍未能达成共识.事实上,几何本身是无所不在的.真正的关键之处并不在于教的内容,即教些什么,而在于教的方法,即如何施教.中小学的数学课应当采取代数与几何并重的方式进行教学.     

Students’ Perceptions of Mental Health Counseling in the United Arab Emirates (UAE)

Counseling services in the United Arab Emirates (UAE) have focused on counseling in the elementary and secondary schools. To date, the idea of the private practitioner of mental health counseling has been virtually nonexistent. However, education officials at the University of the United Arab Emirates (UAE) have been exploring the option of following the international trends of preparing students for mental health counseling services, with special emphasis in marriage and family. A counselor education degree would allow individuals to operate private practices to address various concerns that impact individuals within the society at large. No instruments that measure perceptions of counseling from an international perspective were found for the purposes of this study. Therefore, it was necessary for the authors to devise and test a new tool. Surveys were completed by a sample of 141 undergraduate students regarding their perceptions of the importance of counseling in UAE society and the role of the counselor in society and other general questions regarding perceptions of counseling. With this initial effort, psychometric properties of the ‘Perceptions about Counseling Survey’ appeared promising. Results revealed that students had a favorable view toward the role of the counselor in UAE society. Results further revealed that students perceived the counseling profession as favorable. Given that the participants were predominately female, the results were analyzed from the social and cultural perspective of women in Arab society and the social psychological theory of ‘attitude’ is considered as a contextual backdrop.
