Spanish Teachers' Epistemological and Scientific Conceptions: Implications for teacher education1

We present the theoretical framework, the central issues, bibliographic antecedents, and most relevant results of three studies concerning Spanish teachers' epistemological and scientific conceptions. The samples analysed present a majority tendency towards an absolutist view of knowledge and an empiricist conception of science. In our view, this represents a real obstacle to constructive and active professional development. Finally, we argue the need for an epistemological education of teachers that is closely linked to the design and development of the school curriculum, and that does not reproduce the traditional academicist-type models.     

Changes in involvement in homework throughout compulsory secondary education / Cambios en la implicación en los deberes escolares a lo largo de la Educación Secundaria Obligatoria

This paper analyses the changes found in students’ involvement in homework throughout the four grade levels of compulsory secondary education in Spain (ages 12–15). It also analyses the relationship between the changes in students’ involvement in homework throughout schooling and motivational and emotional variables related to homework. Findings indicated that: (a) the amount of homework completed and homework time management diminished slightly throughout the grade levels researched; however, this result is clearer in terms of the amount of homework completed; (b) prior academic achievement is significantly related to the variables associated with students’ involvement in homework; (c) the motivational and affective variables researched explained statistically significant variance related to two of the three dependent variables associated with involvement in homework; and (d) the association between the motivational and affective variables and involvement in homework is lower.     

A multilevel study of self-beliefs and student behaviors in a group problem-solving task

Relationships among self-construal, self-efficacy, and group behaviors during a group problem-solving task with friends and acquaintances were hypothesized. The sample comprised 126 students in Grades 8–11, from 5 randomly selected government high schools, organized into 42 groups. Data collection involved self-reports and observations. Self-report data measured self-construal, self-efficacy for working with friends, and self-efficacy for working with acquaintances, and the observational data captured salient student behaviors. Data were analyzed using exploratory factor analysis and multilevel modeling. Self-efficacy for working with acquaintances was related to the development of ideas and also the critical review of ideas in groups. This study provides insights into the relatively underexplored phenomena of group work with friends and acquaintances.     

Effects of elements or compound preexposure on conditioned taste aversion as a function of retention interval

The effects of element or compound preexposure and retention interval were examined in three experiments with the taste-aversion paradigm. In Experiment 1, preexposure to the elements of a compound flavor produced less latent inhibition to the compound than did preexposure to the compound itself when a 1-day preexposure-conditioning interval was used. However, preexposing the elements or the compound resulted in equivalent latent inhibition effects when a 21-day retention interval was used. In Experiment 2, a similar pattern of results was observed when the conditioning-test interval was manipulated. Experiment 3 explored the effect of element or compound preexposure when preexposure and test were carried out in different contexts. Attenuated latent inhibition following preexposure to the elements was found when preexposure and test were carried out in the same context. In contrast, preexposure to the elements resulted in as much latent inhibition as did preexposure to the compound when the context was switched from preexposure to testing. The implications of these findings for a retrieval-oriented view of latent inhibition are discussed.     

Brexit: some implications for African higher education

This article considers how the decisions of the UK government, following the Brexit referendum, may impact on higher education in Africa. Ghana and South Africa are the two countries chosen to exemplify the claim that academic staff in African higher education will lose opportunities to acquire experience in British universities. Academic mobility between Africa and the UK is expected to fall significantly following Brexit.     

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.     

Neighborhood poverty and early transition to sexual activity in young adolescents: a developmental ecological approach

This study examined how the link between neighborhood poverty and the timing of sexual initiation varies as a function of age, gender, and background characteristics. A sample of N = 2,596 predominately White Canadian adolescents from the National Longitudinal Survey of Children and Youth was used. Sexual initiations occurring between 12 and 15 years old were considered. Results showed that younger adolescent females who lived in poor neighborhoods and who had a history of conduct problems were more likely to report early sexual activity. Peer characteristics partly accounted for this susceptibility. Among adolescent males, no direct neighborhood effects were found, but those who had combined risks at multiple levels appeared more vulnerable. The theoretical and practical implications of these findings are discussed.     

A social-constructivist approach in physical education: Influence of dyadic interactions on tactical choices in an instructional team sport setting

The purpose of this study was to analyze the role of dyadic verbal peer interactions in a team sport such as handball. Participants, 20 boys and 20 girls aged between 11 and 12, were assigned to two learning condition groups. The task was an instructional setting in team handball (2 attackers against 1 defender in each half court). The experimental group with verbal exchanges was expected to obtain higher performances in the post-tests than those who had not interacted verbally between playing sequences. The secondary objective was to investigate whether dyadic gender had an effect on tactical choice and cognitive skills in playing games. The experiment demonstrated the superiority of the dyadic verbal interaction group over the non-interactive group as regards tactical choices and action projects. It also showed gender differences since males performed better females with regard to action efficiency. The results are discussed within the theoretical framework of the social psychology of acquisition and development and within that of teaching for understanding. In conclusion, the socio-constructivist approach would seem to be pertinent in team sport decision-making tasks.     

Representations over the Earth’s shape and the process of day and night from Nahua indigenous schoolchildren / Representaciones sobre la forma de la Tierra y del proceso día y noche en niños de escuelas indígenas Nahuas

This research presents the way in which children from a Nahua indigenous community build representations of the Earth’s shape, as well as the process that causes day and night. Concepts from school and local culture were studied. For the first case, a questionnaire was applied to 331 children, out of which 38 children were then interviewed on the topics from the questionnaire. For the cultural ideas, three teachers from the region and 30 children from the sample were interviewed. The results show that the representations depend on the form of questioning and the existence of three models: a flat structure with a celestial dome and mechanisms that hide or remove the Sun or the Moon in order to create day and night; a spherical structure with a surrounding sky, where the Sun and Moon rise and set; and a transitional model with a hollow sphere, flat surface and celestial dome. Cultural ideas do not appear to have any influence over these models, probably due to a loss of the community’s cosmogonic knowledge and the age of the children.
