Teachers’ moral values and their interpersonal relationships with students and cultural competence

This study explored whether and how teachers’ beliefs about moral values are reflected in the student-teacher relationships (i.e. levels of control and affiliation in teachers’ and students’ perceptions of this relationship), and in teachers’ cultural competence. A positive association was found between teachers’ paternalist beliefs and their own perceptions of control. A negative association was found between teachers’ liberal beliefs and students’ perceptions of affiliation. Positive associations were found between teachers’ liberal beliefs and the metacognitive and motivational components of cultural competence. We discuss the implications for preparation of teachers to reflect on the manifestations of their beliefs in practice.

What do graduates think? An analysis of intention to repeat the same studies and university

The present work analyzes the key factors in the university experience that influence graduates' intention to repeat the same studies and the same institution, given the hypothetical option – based on hindsight – of selecting afresh a course and place of study. The work is inspired by the theory of planned behavior [Ajzen, I. (1985). From intentions to actions: A theory of planned behavior, in action control: From cognition to behavior. New York: J. Kuhl and J. Beckmann; Ajzen, I. (1991). The theory of planned behavior. Organizational Behavior and Human Decision Processes, 50, 179–211]. This analysis is based on the opinion of graduates in relation to a set of variables that together form the intention to repeat, namely quality of education; services and facilities; preparation by the university for employment; fitness-for-purpose of studies for the job market; capacities and skills acquired; the time taken to find work following graduation; current salary; and satisfaction with current employment. Using multiple regression models, the principal components of service quality in a university context are determined. The findings indicate that the quality of the educational process is the most influential aspect both in the intention to repeat the same studies and also in the intention to repeat the same university. Services and facilities have a marked influence on the latter, while the time taken to find employment and current salary are the two aspects with the least impact.     

Conflicts in teachers’ professional practices and perspectives about inclusion in Icelandic compulsory schools

Inclusive education policy, now the norm in many parts of the world including Iceland, is highly dependent on teachers for its successful implementation. Research on inclusion often attempts to identify teachers’ attitudes of inclusion (against/for). This article takes a different approach. It focuses on teachers’ perspectives of their professional practices; that is, how teachers understand what it means to be and practise as a teacher. We interviewed 10 Icelandic compulsory school teachers and also examined teaching logs and associated documents. The findings suggest that the teachers participating in this study have conflicting expectations towards their professional practice. They have unclear ideas about the inclusive ideology, and external factors influence teachers’ perception of their professional practice more than reflective practices. We suggest that these findings may well be applicable beyond the Icelandic context, and that they have implications for the overall in-service and pre-service education offered to teachers.     

On the acquisition of some basic word spelling mechanisms in a deep (French) and a shallow (Spanish) system

An experiment was carried out to compare the time course of the acquisition of two basic spelling mechanisms in Spanish, a shallow system, and French, a deep system. The first was lexical. It relies on the orthographic lexicon, a hypothetical structure containing the orthographic representations of words accessible for word spelling. To evaluate its contribution the participants were asked to spell words of high and low frequency containing phonemes which can take different graphemic values. The second mechanism relies on sub-lexical processes. Its contribution was evaluated asking the participants to spell words containing consistent phoneme-to-grapheme translation pairs which were identical in Spanish and French. Two contrasting predictions were considered, one derived from the Orthographic Depth Hypothesis (ODH, Frost, 2005) and the other from the Self-Teaching Hypothesis (STH, Share, 2004). According to the ODH, the orthographic lexicon should develop more rapidly in French than in Spanish because Spanish spellers can rely on phoneme-to-grapheme translation mechanisms to spell most words, meaning that they do not need to resort to the orthographic lexicon. In contrast, the STH suggests that effective identification of a word gradually generates its orthographic representation. The results revealed that both spelling mechanisms develop far faster in Spanish than in French. The fact that word frequency effects appeared earlier in Spanish than in French, indicating that the orthographic lexicon incorporates words more rapidly in a shallow than in a deep system, is clearly incompatible with the ODH and easier to handle in the context of the STH.     

Sex Education Representations in Spanish Combined Biology and Geology Textbooks

Sex education is principally dealt with as part of the combined subject of Biology and Geology in the Spanish school curriculum. Teachers of this subject are not specifically trained to teach sex education, and thus the contents of their assigned textbooks are the main source of information available to them in this field. The main goal of this study was to determine what information Biology and Geology textbooks provide with regard to sex education and the vision of sexuality they give, but above all to reveal which perspectives of sex education they legitimise and which they silence. We analysed the textbooks in question by interpreting both visual and text representations, as a means of enabling us to investigate the nature of the discourse on sex education. With this aim, we have used a qualitative methodology, based on the content analysis. The main analytical tool was an in-house grid constructed to allow us to analyse the visual and textual representations. Our analysis of the combined Biology and Geology textbooks for Secondary Year 3 revealed that there is a tendency to reproduce models of sex education that take place within a framework of the more traditional discourses. Besides, the results suggested that the most of the sample chosen for this study makes a superficial, incomplete, incorrect or biased approach to sex education.     

Promoting Science Outdoor Activities for Elementary School Children: Contributions from a research laboratory

The purposes of the study were to analyse the promotion of scientific literacy through practical research activities and to identify children's conceptions about scientists and how they do science. Elementary school children were engaged in two scientific experiments in a marine biology research laboratory. A total of 136 students answered a questionnaire about their previous habits towards science and carried out the following actions: (1) a guided visit to the laboratory, (2) a brief presentation of the research theme, (3) the development of two experiments, and (4) a questionnaire about the experiments and science conceptions. The research methods included observation, document analysis, and content analysis of the answers to the questionnaires. Additionally, each visit was video recorded in order to design learning materials. The results revealed that most of the pupils were able to follow every stage of experimentation. However, some of them misinterpreted results and conclusions. One implication of the study is that this type of outdoor activity is extremely important to promote meaningful science learning in children, but more care should be taken in practical science activities so that children can overcome some common difficulties when performing scientific inquiry.     

Introduction to Semiconductor Physics in Secondary Education: Evaluation of a teaching sequence

The present article presents a didactic proposal oriented to teaching notions of semiconductor physics in secondary education. The methods and the results of a pilot study designed to analyse the effectiveness of a teaching sequence on the topic are also described. The subjects were 60 students, aged 14–15 years, of a secondary school in Seville, Spain. The levels of knowledge acquired by the students were evaluated by means of a test and personal interviews, which we also used to detect the most frequent obstacles they encountered against learning. Also, we employed personal interviews and analysis of the students’ notebooks to evaluate their attitudes towards semiconductor physics and its learning, and to evaluate the degree to which the teaching sequence fosters cooperative learning and the self‐regulation of learning. The results indicated that the students in general acquired ideas and reasoning in the appropriate line, although with some mistakes or inaccuracies with respect to scientific conceptions, and acquired positive attitudes towards the learning of semiconductor physics, with a high degree of motivation during the teaching–learning process. The conclusion is that it is possible to initiate teaching the basic notions of semiconductor physics in secondary education, although it is necessary to continue going deeper into the topic with new research. As a proposal for improvement in future actions, we formulate new objectives oriented at overcoming the students’ commonest obstacles against learning with respect to the topic.
