As arguments for the liberalization of education grow more heated, how are we to approach Japanese schools as a community? This paper clarifies the basic concept of the "small schools" theory typified by the METI "Future Classrooms" (functionalist and individualist reorganizations), and organizes the relevant points of debate. In particular, the paper examines the issues of individuation and personalization represented by individual optimization of learning, promotionism (an attendance-based credit acquisition) and retentionism (an achievement-based credit acquisition), merit promotion and social promotion, and grade and class systems. Based thereon, the paper presents a perspective on the reconstruction of the communality and publicness of Japanese schools. [Translated by Nadezhda Murray.]

This paper examines the influence of single parenthood on children's academic achievement in Japan. While some studies have examined the academic achievement gap associated with family structure, a limitation of existing research is the focus on differences between the mean levels of academic achievement of children in single-parent and two-parent families. Using data from the Programme for International Student Assessment (PISA) conducted by the Organisation for Economic Co-operation and Development (OECD) in 2012, this paper investigates the effects of single parenthood across the entire distribution of children's academic achievement by using quantile regression techniques. The results of quantile regression analyses indicated that the magnitude of the academic achievement gap between children in single-parent and two-parent families was not equal for each quantile of the conditional distribution of children's academic achievement. The negative effect of single motherhood on children's academic achievement was more profound at lower quantiles, whereas the negative effect of single fatherhood was more profound at the median level. Furthermore, the extent to which parents' education levels accounted for the negative effects of single parenthood was not equal for each quantile of the conditional distribution of children's academic achievement. The effects of single parenthood at lower quantiles were not well explained by parents' education levels, and this tendency was especially obvious in the academic achievement of children in single-father families. This result suggests that low academic achievement of children in single-mother families may be caused by the mothers' low education levels and accompanying low income, whereas poor academic achievement of children in single-father families is likely to be mainly due to the absence of mothers rather than the fathers' low education levels. Based on the empirical evidence obtained in this paper, policy implications regarding the significance and limitations of economic support for single-parent families in terms of reducing educational inequality are discussed.

The concept of educationalization refers to the government's tendency to impose heavy responsibilities to solve social problems on the school system. In this paper, after briefly reviewing the concept of educationalization, I will show that it is a ubiquitous phenomenon in contemporary Japan through three cases. This will prove that school reforms intended to fix social problems are poorly resourced and powerless to change schools in general. This stagnation is due to (1) immature professionalism in educators, (2) loss of motivation for "conspicuous consumption", and (3) the absence of ideals, beliefs, and values to be expressed in school reform. Elsewhere, another series of school reforms are much favored, well-funded and powerful in Japan. After posing anti-ijime policies as the best example, I describe and analyze the background of this type by introducing the concept of "officialization of school problems". Strongly supported by school consumers, it has successfully received a hegemonic position. However, under the hegemony the relation between school and environment is over-simplified by the logic of neo-liberalism and neo-conservatism. After comparing both types, we find a modest utility of educationalization: it could interrupt the perpetuation of hegemonic ideologies and make it possible to see the outer world in its complicated reality.

In the past decades, income inequality has risen in most developed countries. There is growing interest among economists in international comparisons of economic and educational mobility. This is aided by the availability of internationally comparable, large-scale data. The present paper aims to make three contributions. First, we introduce the Japan Child Panel Survey (JCPS), the first longitudinal survey of school-age children that includes cognitive and non-cognitive measures, and plentiful household information. The JCPS was developed to measure dynamic inter-relationships among children's academic and social outcomes, their family background, and local policy and environment, in a way that allows comparison of the results with international data. Second, based on JCPS data, we present selected results of the dynamics of inequality in multiple indicators of children's educational and behavioral outcomes. We found that changes in cognitive achievement across parental income groups, the degree of mobility of cognitive test scores, and the correlation between the difficulty score and parental education in Japan are similar to those of other countries, such as the United States, United Kingdom, Australia, and Germany. Finally we discuss issues underlying the globalization of education research based on our experiences with the JCPS. We discuss reasons and strategies for further globalization of education research in Japan, and propose suggestions as to how Japanese education research can move toward better international collaboration, particularly in research on economic and educational mobility.

The recent "Nationwide academic achievement and study situation survey" was clearly influenced by the idea of "authentic assessment", an educational assessment perspective focused on "quality" and "engagement". However, when "performance assessment", the assessment method corresponding to this focus, is adopted in academic achievement surveys, it runs the risk of turning into a rigid hollow structure. In this paper I will reflect on the ideal application of performance assessment in academic achievement surveys, and will investigate the concepts of "consequential validity", "equity", and "moderation" in regard to their potential to further develop the discourse.

We reported the major findings of our research based on our own academic achievement tests towards elementary school and junior high school pupils in 2002. We then pointed out the fact that the differences of achievement between social groups have been expanded. Nowadays, that issue is seen to be one of the most serious educational problems in contemporary Japan. Although the differences of various educational outcomes such as academic achievements or educational aspirations between social groups are always emphasized, it is surprising that they seldom discuss about the ways in which those differences could be made smaller. I myself have been exploring the issue in these several years. In this paper, I will describe the progress and the future directions of our academic exploration on this particular educational issue.
