Reading Other People’s Minds Through Word and Image

This article considers how emotions can be conveyed through the interaction of word and image in picturebooks addressed to young readers. The theoretical framework employed in the article develops ideas from cognitive literary theory, adapting it to the specific conditions in which there is a significant difference between the sender’s and the recipient’s cognitive levels. The concept of emotion ekphrasis is used to demonstrate the various ways of representing emotions, and special attention is paid to the issues of mind-reading, empathy and other aspects of recipients’ affective engagement. The theoretical argument is illustrated by picturebooks by Max Velthuijs, Shaun Tan, Anthony Browne, and Maurice Sendak.     

Differential effect of university entrance score on first-year students’ academic performance in Portugal

The main goal of this study is to show that the association between university entrance score and first-year students’ academic performance varies randomly across courses after controlling for students’ sociodemographic, schooling trajectory and motivational variables. The sample consists of 2697 first-year students who were enrolled in 54 courses at a Portuguese public university in 2015/16. Multilevel modelling of academic performance suggests that 34% of variability in grade point average is due to differences among courses and that 80% of such variability is explained by the field of study, whether the university is the student’s first choice, and the student’s gender, age and parents’ level of education. In addition, the results corroborate that the university entrance score is the strongest predictor of first-year academic performance.     

Learning Gene Expression Through Modelling and Argumentation

There is emerging interest on the interactions between modelling and argumentation in specific contexts, such as genetics learning. It has been suggested that modelling might help students understand and argue on genetics. We propose modelling gene expression as a way to learn molecular genetics and diseases with a genetic component. The study is framed in Tiberghien’s (2000) two worlds of knowledge, the world of “theories & models” and the world of “objects & events”, adding a third component, the world of representations. We seek to examine how modelling and argumentation interact and connect the three worlds of knowledge while modelling gene expression. It is a case study of 10th graders learning about diseases with a genetic component. The research questions are as follows: (1) What argumentative and modelling operations do students enact in the process of modelling gene expression? Specifically, which operations allow connecting the three worlds of knowledge? (2) What are the interactions between modelling and argumentation in modelling gene expression? To what extent do these interactions help students connect the three worlds of knowledge and modelling gene expression? The argumentative operation of using evidence helps students to relate the three worlds of knowledge, enacted in all the connections. It seems to be a relationship among the number of interactions between modelling and argumentation, the connections between world of knowledge and students’ capacity to develop a more sophisticated representation. Despite this is a case study, this approach of analysis reveals potentialities for a deeper understanding of learning genetics though scientific practices.     

Students’ understanding of the number line / Estudiantes pensando en la recta numérica

We studied the conceptions of students coming from secondary education and university regarding the number line as a representation of real numbers. In the context of a wider questionnaire, 307 students were presented with a task consisting of two verbal items and one graphic item related to the number line. The students were all at different levels in their study of mathematics (in the third, fourth or fifth year of secondary education, or at the beginning or advanced stage of a university degree in mathematics, biology or physical education). A gradient in the depth of the students’ conceptions, associated with the level of their studies in mathematics, was found. This gradient extends from the estrangement of facing the problem or a conception of a drawn or physical matter line, which was associated with students with a lower level of mathematical studies, passing through a vision centred around potential numeric density or a line containing points (discrete), up to an instrumental conception of the line as supportive of magnitudes in advanced students of biology and focusing on continuity sustained by advanced students of mathematics.     

Education policy and equality in France: the socialist years

This article analyses the design of French Socialist egalitarian education policy, defined in terms of a number of indicators: organizational aspects of the education system, financial aspects of education policy and the size of the education system. It considers the extent to which the Socialists altered the institutional structure of the education system in order to create opportunities for lower class pupils or students to study. The performance of the Socialist government suggests that the institutional structures of education tend toward a high degree of continuity and are difficult to change in a short period of time. Nevertheless, despite this pattern of continuity, the Socialists did reform the education system in a way that seems slightly more egalitarian. The article does not attempt to provide a comprehensive explanation of this continuity, but points out some of the factors that account for continuities in certain elements of education policy related to the aim of equality.     

The Generalizability of Content Validity Ratings

The problem of assessing the content validity (or relevance) of standardized achievement tests is considered within the framework of generalizability theory. Four illustrative designs are described that may be used to assess test-item fit to a curriculum. For each design, appropriate variance components are identified for making relative and absolute item (or test) selection decisions. Special consideration is given to use of these procedures for determining the number of raters and/or schools needed in a content-validation decisionmaking study. Application of these procedures is illustrated using data from an international assessment of mathematics achievement
