The placebo effect, a response observed during the placebo arm of a clinical trial, is produced by the psychobiological action of the placebo as well as by other potential contributors to symptom amelioration such as spontaneous improvement, regression to the mean, biases, concurrent treatments, and study design. From a psychological viewpoint, there are many mechanisms that contribute to placebo effects, including expectations, conditioning, learning, and anxiety reduction. Placebo responses are also mediated by opioid and non-opioid mechanisms including dopamine, serotonin, cholecystokinin, and immune mediators. During recent years, a trend towards increased placebo effects in clinical trials of neuropsychiatric drugs has been noted. Indeed, the placebo effects observed in clinical trials constitute an increasing problem and interfere with signal-detection analyses of potential treatments. Several potential factors including protocol/study design and conduct related factors may account for the placebo effect observed in clinical trials. This paper reviews key issues related to this problem and aims to identify potential solutions.

Objectives: The purpose of this systematic review was to understand clinical usefulness of Emotional Freedom Techniques (EFT) on students' mental health. Methods: Ten databases were included to extract clinical studies on effects of EFT intervention with students. Characteristics of selected studies were described, and biases were assessed with Risk of Bias (RoB) or Risk of Bias Assessment for Non-Randomized Studies (RoBANS). Results: A total of 14 clinical trials were extracted for analysis. There were 8 randomized-controlled trials (RCTs), 2 non-randomized-controlled trials (nRCTs), and 4 before-after studies. EFT have significant clinical usefulness in public speaking anxiety, test anxiety, stress, depression, learning related emotions, adolescent anxiety, and eating issues. The risk of selection bias in most studies was high or uncertain. Conclusions: EFT is an effective clinical technique for managing students' mental health issues. However, the included studies have been conducted with relatively poor quality and small sample size. Clinical trials with high quality study design and well-designed EFT education programs are needed to generalize clinical usefulness.

For years, research on the impact of students' attitudes on learning has maintained a spot amongst the most highly discussed topics in education. Particularly, over the past decades, researchers have made great strides in better understanding attitudes toward computers. This article presents a critical review of the current state of research by re-examining how attitudes toward computers have been studied. First, the review introduces an overview of the theoretical foundations and the origins of research on attitudes toward computers. Then, the article summarizes previous literature and knowledge about computer attitudes and provides a review of major findings from research on the effects of some factors affecting the formation of computer attitudes. The discussion reveals a number of major issues and challenges, which include unclear characterization of computer attitudes, problems with measurement tools, and the lack of studies using methods other than brief questionnaires. The unsolved problems cause conflicting, inconsistent and inconclusive results and affect interpretation in the study of computer attitudes. The article also suggests the main recent and future directions of research on attitudes toward computers. Finally, it concludes by providing implications for educators.

The present study examined the role of language proficiency in dyadic discourse in the organization of repairs and the distribution of linguistic features contained in repairs. One native speaker of English and five non-native speakers participated and formed three dyads: one same-proficiency NNS-NNS (non-native speaker), one different-proficiency NNS-NNS, and one NS (native speaker)-NNS dyads. Results showed that overall repair patterns in this type of interaction were more conversational than didactic, and that the degree of difference in proficiency between the participants in the dyad influenced repair patterns and the distribution of linguistic features in relation to repair patterns. Also, discussed in the present paper are some implications of the results and other issues related to language learning.

The purpose of this study was to investigate the influence of the integrated atmosphere environmental education program on environmental attitudes for 5th graders in elementary school. The major results of this study were as follows. First, the developed atmosphere environmental education program had a positive effect on environmental attitudes of elementary students. Second, it also had a positive effect on their interest and desire of atmosphere environment issues. Third, it had a positive correlation among the 3 subdomains of cognitive, affective and behavioral. In conclusion, the atmosphere environmental education program is more directly effective than lectures on environment following the curriculum to improve students' attitudes toward environment. Therefore, it is required that more systematic research should be done linking with teaching and learning methods, as a follow-up activity.

Schools are one of the critical social infrastructures in a society, the first place for social activity and the most important indoor environment for children besides the home. Poor IAQ in classrooms can increase the chance of long-term and short-term health problems for students and staffs; affects productivity of teachers; and degrade the student learning environment and comfort levels. The primary objective of this paper is to review and summarize available scientific evidence on indoor air quality of schools and related health effects in children. It was found that the indoor air pollutant levels in school buildings varied over a wide range in different parts of the world depending on site characteristics, climatic conditions, outdoor pollution levels, occupant activities, ventilation type and building practices. Among the indoor air pollutants, particulate matter concentrations were found to be very high in many schools. Outdoor pollutant sources also play a major role in affecting the IAQ of the school building. Hence, scientific knowledge on sources of indoor pollutants, quantification of emissions, temporal and spatial dispersion of pollutants, toxicological properties, chemical and morphological characteristics of the pollutants and associated health risk among children in the school buildings are essential to evaluate the adequacy and cost effectiveness of control strategies for mitigating the IAQ issues.

In this study, we used an analysis of the literature on socio-scientific issues (SSI) classes to examine domestic SSI class research and to determine the characteristics of SSI class research for each subject. A search for papers related to SSI classes published in Korea Citation Index-listed journals and candidate journals of the Korea Research Foundation found 95 relevant papers, which were then categorized according to participants and topics. Studies with both pre-service and experienced teachers attempted to investigate SSI-related perceptions. Studies of pre-service teachers tended to examine the level and development pattern of argumentation or to analyze decision-making characteristics and informal reasoning. Studies of experienced teachers tended to analyze instructional expertise in SSI teaching activities, focusing on teachers with substantial SSI teaching experience. Middle and high school students-related studies examined student decision-making and reasoning processes in SSI learning activities, developed SSI class programs, and analyzed educational effects. Examining the characteristics of SSI classes for elementary school students was difficult because few such studies have been published. However, the characteristics that elementary school students show in SSI learning situations could be inferred. A plan to revitalize SSI classes in the elementary science education field from the perspective of teacher education and class research is suggested.

SSI instruction can be an effective tool to promote key competencies for future citizens. Our assumption of the study is that applying the concept of collective intelligence in the context of SSI learning would facilitate the learning. Thus, we designed and implemented Collective Intelligence-based SSI instruction over almost a year and observed the effects of the instruction on enhancing students' collaboration, information management, critical thinking, and communication skills. Twenty 9th grade students enrolled in a science-gifted program voluntarily participated. Data was collected by administering a questionnaire to examine the skills before, in the middle of, and after the instruction, and by conducting classroom observations and focus student group interviews. The results indicated some degree of improvement in their targeted skills. First, they experienced the expansion of their thoughts by actively sharing information and ideas using the web platform. Second, they became more flexible and open to different points of views in order to accomplish a common goal. Third, they appreciated having independent time and space to explore their own positions on the issues and to search necessary information, and believed that the process encouraged them to more pro-actively participate and communicate in the group debates. Lastly, they positively perceived the values that collaboration with diverse group members could produce.

Observation of the current Korean medical education and training system shows that certain negative traits of unchangeable solidification engraft themselves so deeply into the overarching system that they are now hampering the state of the national health welfare. Focusing only on undergraduate medical education, we can point out some glaring side-effects that should be of concern to any stakeholder. For instance, a graduate can legally begin his career as an independent practitioner immediately after passing the licensing exam and return to the old stuck school-year system of 2-year-premedical and 4-year-medical programs where outcome-based and integrated curricula are incomplete and unsatisfactory. In terms of learning opportunities, the balance between patient care and public health, as well as that between in-hospital highly specialized practice and community-based general practice, has worsened. Every stakeholder should be aware of these considerations in order to obtain the insight to forge a new direction. Moreover, our medical schools must prepare our students to take on the global roles of patient care within the Fourth Industrial Revolution, health advocacy for the imminent super-aged society, and education and research in the bio-health industry, by building and applying the concept of academic medicine. We will need to invest more resources, including educational specialists, into the current undergraduate medical education system in order to produce proper outcomes, smart curriculum, innovative methods of teaching and learning, and valid and reliable monitoring and evaluation. The improved quality of undergraduate medical education is the starting point for the success of the national system for public health and medical care as a whole, and therefore its urgency and significance should be emphasized to the public. The medical society should go beyond fixing what is broken and usher in a new era of cooperation and collaboration that invites other health professionals, governmental partners, law-makers, opinion leaders, and the general public in its steps toward the future.

Performance assessment is recognized as a proper evaluation method to integrate the teaching and learning process into the evaluation one and as an essential means to produce meaningful evaluation results. However, it has deteriorated into a teacher-centric evaluation method with the students excluded due to the cost and time issues and the heavy workload on the teachers. Those changes have affected the reliability of the assessment results. This study developed and applied a web-based performance assessment system by using Moodle, open source software, to help the teachers efficiently run performance assessment in school and the students increase their learning effects. As a result, it lifted the burden of system development from the shoulders of the teachers trying to do web-based performance assessment and solved the reliability issue raised in the old peer evaluation approach through diverse strategies offered by Moodle.
