Peer mediation: citizenship and social inclusion revisited

In sociometric research tradition, popularity is defined as the degree to which children are liked or accepted by their peers. However, research indicates that two definitions of popular students should be distinguished: (1) popular students as those students who are well liked by many and disliked by few peers, and (2) popular students as those students who are described as popular by their peers. The main purpose of the present study was to examine the relationship between sociometric and peer perceived popularity in Slovenian students of different grades of elementary and secondary school. Additionally, the age differences in the relationship between sociometric and peer perceived popularity were examined. Another purpose of the study was to investigate the differential relationships between concepts of popularity and some students' characteristics. The participants were 321 boys and 329 girls who ranged from the 5th grade of elementary school (the mean age 11.04 years) to the 3rd grade of secondary school (the mean age 17.02 years). The results of this study confirm previous findings that peer perceived popularity is a construct that is distinct from sociometric popularity. There are some substantial differences in relations between indices of perceived popularity and sociometric indices between elementary school students and secondary school students—i.e. between early adolescents and middle to late adolescents. It seems that perceived popularity and sociometric popularity are rather similar constructs in elementary school students, whereas in secondary school students they become almost unrelated to each other. Based on these findings, the terminological issues are discussed and some conclusions are made.     

NEIGHBORHOOD SOCIOECONOMIC WELL‐BEING,HOME LITERACY,AND EARLY LITERACY SKILLS OF AT‐RISK PRESCHOOLERS

In response to growing research and policy interest in the developmental contexts of early literacy, this study examined relations between neighborhood socioeconomic well‐being, home literacy (parent–child shared reading and number of books at home), and directly assessed early literacy outcomes among 551 Head Start students in the fall of preschool. In Structural Equation Models, neighborhood socioeconomic well‐being predicted home literacy, which in turn predicted early literacy (a latent variable derived from receptive vocabulary, letter‐word identification, and concepts about print). Implications for future research concerning parent involvement at home in the context of neighborhoods and the early literacy of at‐risk preschoolers is discussed.     

Cultural differences in how individuals explain their lying and truth-telling tendencies

This study investigated how cultural differences between Korea and the United States in attitudinal and normative components affect individuals’ explanation of their intentions to lie or tell the truth. Study 1 examined individuals’ intentions to base their lying or truth-telling tendencies on attitude-related reasons (i.e., attitudinal reasons) and subjective norm-related reasons (i.e., normative reasons). Study 2 examined individuals’ evaluation of a person who used attitudinal reasons or normative reasons to explain his/her behaviors of lying or truth-telling. The results showed that neither culture used one type of reason consistently across different behaviors. Instead, the types of behaviors influenced the way attitudinal and normative components were related to behavioral intentions. The attitudinal component was important for individuals’ explanations of their attitudinal reasons to lie and to tell the truth and that the normative component was important for individuals’ explanations of their normative reasons to lie. However, both the attitudinal and normative components were important for individuals’ explanations of their normative reasons to tell the truth. Cross-culturally, Koreans were more likely to use normative reasons when they had to explain why they intended to lie for a friend, whereas Americans were more likely to use normative reasons when they had to explain why they intended to tell the truth. In addition, Koreans and Americans had different preferences for each reason type depending on the type of behavior probably because Koreans, as compared to Americans, tend to view lying for a friend less negatively.     

A perspective on education for sustainable development: Historical development of environmental education in Indonesia

This article examines the historical development of environmental education (EE) in Indonesia with emphasis on the non-formal sector, and applies its findings to the discussion on education for sustainable development (ESD), which seldom draws on case studies from developing countries. Local socio-economic and political conditions have made EE in Indonesia similar to ‘ESD’ in terms of its topical scope involving various social issues, although whether it should be referred to as ESD remains unclear. In contrast to the existing concerns about ESD, it involves critical views on the prevailing models of (neo-liberal) economic development. This article also shows that EE, like ESD, is at risk of exploitation by vested interests.     

Influence of team identification,game outcome,and game process on sport consumers’ happiness

The purpose of the study is to examine the relative effects of game process (i.e., boring versus exciting) and outcome (i.e., losing versus winning) on sport consumers’ happiness depending on their level of team identification. The authors investigated how sport consumers’ levels of happiness are different after recalling (Study 1) and imagining (Study 2) a game when the positivity of the game process and the outcome contradict each other. Results indicate that sport consumers with high team identification exhibited greater degrees of happiness after recalling and imagining a boring win game compared to an exciting loss game. Meanwhile, sport consumers with low team identification exhibited similar degrees of happiness between a boring win game and an exciting loss game.     

Measuring knowledge integration: Validation of four‐year assessments

Science education needs valid, authentic, and efficient assessments. Many typical science assessments primarily measure recall of isolated information. This paper reports on the validation of assessments that measure knowledge integration ability among middle school and high school students. The assessments were administered to 18,729 students in five states. Rasch analyses of the assessments demonstrated satisfactory item fit, item difficulty, test reliability, and person reliability. The study showed that, when appropriately designed, knowledge integration assessments can be balanced between validity and reliability, authenticity and generalizability, and instructional sensitivity and technical quality. Results also showed that, when paired with multiple‐choice items and scored with an effective scoring rubric, constructed‐response items can achieve high reliabilities. Analyses showed that English language learner status and computer use significantly impacted students' science knowledge integration abilities. Students who took the assessment online, which matched the format of content delivery, performed significantly better than students who took the paper‐and‐pencil version. Implications and future directions of research are noted, including refining curriculum materials to meet the needs of diverse students and expanding the range of topics measured by knowledge integration assessments. © 2011 Wiley Periodicals, Inc.

Cultural validation of the Maslach Burnout Inventory for Korean students

The purpose of this study was to examine the factorial validity of the MBI-SS in Korean students. Specifically, we investigated whether the original three-factor structure of the MBI-SS was appropriate for use with Korean students. In addition, by running multi-group structural equation model analyses with factorial invariance tests simultaneously for both genders (i.e., males and females) and academic settings (i.e., middle school and high school), we tested whether the factor loading and correlations between factors can be similarly interpreted across the different groups. Results indicated that the MBI-SS is a valid instrument to measure academic burnout of Korean students. Furthermore, results presented the possibility that the MBI-SS could be used regardless of cultural background. Implications for future research and practice and limitations are discussed.     

Modeling of chemotactic steering of bacteria-based microrobot using a population-scale approach

The bacteria-based microrobot (Bacteriobot) is one of the most effective vehicles for drug delivery systems. The bacteriobot consists of a microbead containing therapeutic drugs and bacteria as a sensor and an actuator that can target and guide the bacteriobot to its destination. Many researchers are developing bacteria-based microrobots and establishing the model. In spite of these efforts, a motility model for bacteriobots steered by chemotaxis remains elusive. Because bacterial movement is random and should be described using a stochastic model, bacterial response to the chemo-attractant is difficult to anticipate. In this research, we used a population-scale approach to overcome the main obstacle to the stochastic motion of single bacterium. Also known as Keller-Segel''s equation in chemotaxis research, the population-scale approach is not new. It is a well-designed model derived from transport theory and adaptable to any chemotaxis experiment. In addition, we have considered the self-propelled Brownian motion of the bacteriobot in order to represent its stochastic properties. From this perspective, we have proposed a new numerical modelling method combining chemotaxis and Brownian motion to create a bacteriobot model steered by chemotaxis. To obtain modeling parameters, we executed motility analyses of microbeads and bacteriobots without chemotactic steering as well as chemotactic steering analysis of the bacteriobots. The resulting proposed model shows sound agreement with experimental data with a confidence level <0.01.     

Teachers' Perceptions of Teaching Environmental Issues Within the Science Curriculum: A Hong Kong Perspective

The present study was an exploratory study of Hong Kong secondary school Integrated Science teachers' perceptions of environmental education. Both questionnaire survey and interviews were used. Teachers were classified according to their scores of attitudes, perceived barriers, and current emphasis on teaching environmental education. This study found that Integrated Science teachers' attitudes toward environmental education, skills of teaching environmental education, beliefs in the relevance of Integrated Science to environmental education, and intentions of teaching environmental education in Integrated Science classes were associated with their actual ways of teaching of environmental education. Teachers tended to teach more environmental education if they held more favorable attitudes toward environmental education, had more skills of teaching environmental education, believed more in the relevance of Integrated Science to environmental education, and would actually want to teach more environmental education in Integrated Science classes if there were fewer constraints. Moreover, variations in the teaching of environmental education were reflected by teachers' emphasis on teaching environmental education, and their use of a variety of teaching methods and their regular practices of extracurricular activities on environmental education.
