How many hours of instruction are needed for students to become competent in engineering subjects?

The aim of this work was to compare the curricula of three different agricultural engineering courses and to determine the competence of graduating students in three subject areas in order to identify possible shortfalls in the number of hours of instruction (HI) required for full competence to be attained.

A total of 132 students sat a voluntary examination in the final year of their studies to determine their competence in three subject areas: electrical facilities, machinery and construction. The degree courses completed by these students are meant to provide them with the legal standing required to undertake infrastructure projects in agricultural installations.

This work detected significant differences in the competence of graduates in the mentioned subjects, depending on the number of HI they had received. Students who had received under 120 HI in these subjects were found to be significantly less competent than those who had received more.     

Do Spanish secondary school teachers really value different sorts of procedural skills?

The aim of teaching science at secondary school level is that of achieving the scientific literacy of all citizens. This must involve diverse objectives, among which may be found the development of procedural skills (thought, manipulative, communicative, etc.). The new curricula of many countries provide for these objectives. However, it is important to know to what extent the teaching staff consider them as true content to be taught. In this article, we analyse the opinions of secondary school teachers belonging to schools in north‐western Spain with regard to how they value different types of procedures. Our findings show that the surveyed teachers establish differences between various procedural skills as far as the recognition of their presence in the classroom and their evaluation are concerned, although it may be said that they generally value procedural skills highly. These findings are discussed. In addition, the persistence of traditional conceptions in the teaching of science, as well as the difficulty of assuming that the changes promoted by new curricular approaches are addressed, are highlighted.     

The implication of formal educational activities in old age and its relation to psychosocial indicators / La implicación en actividades educativas formales en la vejez y su relación con indicadores psicosociales

This study analyses some psychosocial dimensions (level and type of activity, self-perceived health, self-efficacy in relation to ageing and social support) in non-dependent older people. The sample comprises students of a university programme for older people (PUM) as well as older people who did not participate in the educational activity. Results show similarities and differences between both groups; namely, the older people on the PUM programme were more physically active and participated more in formal activities. Three profiles of older people were identified: a less active group, with lower scores in the indicators assessed; a second group who were socially active, particularly at a family level, with intermediate levels in the dimensions analysed; and a third group who were very active at a formal level (principally made up of the PUM students) and with the best self-efficacy indices in relation to ageing and self-perceived health. Involvement in formal educational activities is related to more satisfactory and positive profiles in old age, and is a highly relevant resource for the promotion of well-being at this stage of life.     

Positive aspects of the teacher training supervision: The student teachers’ perspective

This paper explores the student teachers’ perceptions about the most positive aspects of the supervision provided during their teaching practice. The authors developed a study based on the reflections of a group of 224 student teachers about their cooperating teacher’s and university supervisor’s performance. Student teacher’s appraisals regarding their supervisors, the learning and progress perceived as resulting from their co-working with more experienced teachers, and the emotional aspects of this relationship are among the main aspects analysed in the study. Results show the importance attributed to the supervisors’ personal features and to the quality of the interactions established with their student teachers. These aspects were clearly regarded as an essential aspect of the student teachers’ emotional balance and resistance to the difficulties emerged during their entrance in the teaching profession. Some differences were perceived in terms of the students teachers’ evaluations regarding the moment of the practicum (beginning versus end) and the type of supervisor (university versus school). Some enquiry and suggestions for future research emerge as final contributions.

Psychometric analysis of a scale for assessing specific competences in tutoring and educational guidance / Análisis psicométrico de una escala para evaluar las competencias específicas en tutoría y orientación educativa

The aim of this study is to validate an instrument for assessing self-perceived tutoring and educational guidance competences in students on the Master’s in Teaching. A historical review of secondary school teacher training shows the need to provide evidence of students’ competence levels. In view of this, a scale has been designed based on the specific competences they ought to acquire. A total of 336 students from the University of Salamanca and Oviedo participated in the study. An exploratory and confirmatory factor analysis of the results of the psychometric test show the good fit of the model globally (RMR = .075; GFI = .969) and incrementally (AGFI = .964; NFI = .960; RFI = .957), thus confirming the validity and reliability of the instrument. Finally, the study concludes by emphasizing the need to study real and self-perceived competence levels in specific areas, and to design suitable instruments to measure these levels.     

Cognitive,Motivational, and Volitional Dimensions of Learning: An Empirical Test of a Hypothetical Model

The principal aim of this research is to contrast empirically a hypothetical model developed on the basis of the fundamental assumptions of current self-regulated learning models. In line with evaluation criteria of model fit, a high rate of congruence between the hypothesized theoretical model and the empirical data was observed. Analysis of the effects between the variables of the model revealed the following relevant aspects: students' predisposition to feel responsible for the results of their academic behavior (internal attribution) is related to positive self-image (academic self-concept), both being important conditions for development of learning-oriented motivation (learning goals). All of this involves selection and use of learning strategies for deep information processing (deep learning strategies), which leads students to assume responsibility with high levels of persistence, perseverance, and tenacity so as to achieve goals defined by the motivational orientation. This persistence and effort to achieve the proposed goals has in turn a positive and significant effect on academic achievement.     

Comparing Teaching Approaches About Maxwell’s Displacement Current

Due to its fundamental role for the consolidation of Maxwell’s equations, the displacement current is one of the most important topics of any introductory course on electromagnetism. Moreover, this episode is widely used by historians and philosophers of science as a case study to investigate several issues (e.g. the theory–experiment relationship). Despite the consensus among physics educators concerning the relevance of the topic, there are many possible ways to interpret and justify the need for the displacement current term. With the goal of understanding the didactical transposition of this topic more deeply, we investigate three of its domains: (1) The historical development of Maxwell’s reasoning; (2) Different approaches to justify the term insertion in physics textbooks; and (3) Four lectures devoted to introduce the topic in undergraduate level given by four different professors. By reflecting on the differences between these three domains, significant evidence for the knowledge transformation caused by the didactization of this episode is provided. The main purpose of this comparative analysis is to assist physics educators in developing an epistemological surveillance regarding the teaching and learning of the displacement current.
