Do perceptions of being treated fairly increase students’ outcomes? Teacher–student interactions and classroom justice in Italian adolescents

In this study, we have investigated the associations between the students’ perceptions of teachers’ interpersonal behaviour and some school outcomes – namely, academic achievement, learning motivation, and a sense of class belonging – considering the mediating role of classroom justice. Moreover, the impact of the school type was analysed. The research was performed on a population of 614 Italian students enrolled in 2 different types of secondary school, one with an academic orientation, the other with a vocational orientation. Structural equation modelling (SEM) was used to see the effect of the teachers’ behaviour on the dimensions of justice (i.e., equality, equity, needs, and interpersonal) and that of all these variables on academic achievement, learning motivation, and class belonging. The mediation role of classroom justice was confirmed by the analyses, and so was the impact of the school's orientation. Limitations to the study and future research ideas have also been outlined.     

Conservation in Physics Teaching,History of Science and in Child Development

The current work is an exploratory study on the ideas thatstudents in their fourth semester of engineering have about ``conservation'. Wereview the Piagetian position on the importance of conservations in logical operational structures inchild development and we comment upon other current trends in cognitive psychology. We discussbriefly the development of conservations in science during the 17th, 18th and 19th centuries and we pointout the contrast between this and how most textbooks introduce this subject. We have also carried out afirst, tentative analysis of the answers given by a sample of these students to a brief questionnaire about``conservation' and ``non-conservation'.
