Environmental Perception as a Diagnostic Probe of Environmental Complexity Levels

Purpose: Educational methods to diagnose and improve the level of environmental conception are required. The present work reports a methodology based on studies about the environmental perception of a university public, divided into general students and those related to the forest sciences, who are involved with disciplines and researches related to e.g. environmental management.

Design/Methodology/Approach: The environmental perception obtained from the graphical representation of environment and the most relevant actions indicated by the students to achieve the environmental conservation, divided in four levels of complexity, were correlated using principal component analysis.

Findings: The students from both groups having the highest scores in environmental perception prioritize actions related to the comprehension and responsibility levels, while the ideal scenario would be to indicate actions related to competence and citizenship. Thus, the complex concept about environment of the students is still incipient and, therefore, educational strategies can be traced based on the profiles obtained.

Practical Implications: The method for environmental perception can be designed for different populations and a scheme relating environmental perception with four levels of actions on behalf of the environmental conservation is proposed to diagnose environmental conceptions, as well as to guide educational strategies about socio-ecological system.

Originality/Value: A semi-quantitative method was developed to estimate, clearly and directly, the level of complexity about the environmental knowledge of university students and, consequently, to predict the actions on behalf of the environmental conservation that they would probably perform.     

Intensive scaffolding in an intelligent tutoring system for the learning of algebraic word problem solving

The term intensive scaffolding refers to any set of conceptual scaffolding strategies that always allow the user to find the solution to a problem. Despite the many benefits of scaffolding, some negative effects have also been reported. These are mainly related to the possibility that a student solves the problems without actually engaging in their content. In this paper, we have used an intelligent tutoring system (ITS) to analyze the effect that intensive scaffolding has on the learning of algebraic word problem solving (AWPS). Two different versions of the ITS, which differ in the amount of scaffolding that they provide, have been created. These two versions were used by two groups of students in Secondary Education, in a quasi‐experimental study. The comparison of pre‐ and posttest scores shows a significant increase of the competence in AWPS in the group that used the ITS with intensive scaffolding.     

The Quality Challenge for Universities: A View from Spain

Universities are centuries-old institutions that inrecent times have undergone important changes as aresult of the expansion of the system of highereducation, the diversification of social demands onthe university, and the increase in public spending onhigher education. In this new context, universitieshave the opportunity to show their capacity foradaptability and their social and intellectualleadership, reacting to the new situation in acreative manner. But to do this they must accept thequality challenge, that is, the responsibilityfor showing that they can do things right and meetsociety's demands with the highest levels of qualityand efficiency. This paper presents how thischallenge must be approached in Spanishuniversities.     

The Problem of Training in Higher Education

As universities are centres of learning, the lecturer/teacher is, so to speak, the basic institutional journeyman who as an academic and scientist devotes much of his/her time to teaching rather than to pure research. The task of teaching, given the massification of universities, the diversity of students, and the advent of the new information technologies, is much more a question of inducing student learning than of mechanically transmitting knowledge. Therefore, newly recruited university lecturers must have come to their posts with an understanding of university pedagogy. As their careers begin, lecturers must be offered continued instruction in the art of teaching and the inducement of learning in others. Good teaching/inducement‐of‐learning work is a contribution to knowledge and should be as well rewarded as the contribution to knowledge that comes from pure research. Prior professional training should also be made available to university teachers taking up administrative responsibilities.     

Rolling: A new technique for the practical teaching in computer science university degree

In this paper we describe a new methodology for practical teaching in the Computer Science University Degree. The methodology is based on the Rolling technique. This technique consists in assign, in a rotary process, tasks, activities and responsibilities to students along an established calendar with the aim of developing a software product. Practical teaching is supported by a student-teacher contract that describes the goal, rules, plan with stages and activities, responsibilities and even the assessment method. Students are organized in groups and teams, emulating a company organization. They develop all the activities of the software engineering process in order to obtain a commercial product (the goal). In this process, students take different responsibilities over the software verification and validation, activities and tasks, and over groups and teams leadership. Along the teaching process, comprehensive information about the working team, time invested, deliverables in each stage, and work/students assessment is gathered. The methodology has been tested for 4 years at the University of Córdoba and the results, described in this paper, have shown an improvement in the students learning as well as in the acquisition of attitudes and skills mandatory for their professional development.     

Using the onto-semiotic approach to identify and analyze mathematical meaning when transiting between different coordinate systems in a multivariate context

The main objective of this paper is to apply the onto-semiotic approach to analyze the mathematical concept of different coordinate systems, as well as some situations and university students’ actions related to these coordinate systems. The identification of objects that emerge from the mathematical activity and a first intent to describe an epistemic network that relates to this activity were carried out. Multivariate calculus students’ responses to questions involving single and multivariate functions in polar, cylindrical, and spherical coordinates were used to classify semiotic functions that relate the different mathematical objects.     

Effects of bilateral and non-dominant practices on the lateral preference in judo matches

This study analysed the effects of bilateral and non-dominant practice on novice practitioners’ lateral preference for judo skills in a combat context (i.e., randori). Thirty sports sciences students (22 men and 8 women; mean age 19 ± 1 years) with right hand, foot, and counterclockwise rotation preferences were divided into 3 groups: bilateral (BG; n = 8), non-dominant (NDG; n = 11), and control (CG; n = 11). Participants received 8 weeks of training at a rate of 3 days per week. The NDG was trained to perform judo skills exclusive with their non-dominant side, while the BG performed every task symmetrically. Before and after training, participants were recorded during two 3-min randoris to obtain the percentage of their engagement in dominant side actions. Pretest percentages were 73.1 ± 19.9%, 77.8 ± 18.8%, and 68.9 ± 27.2% for BG, NDG, and CG, respectively. Post-test values were 75.0 ± 15.6%, 23.3 ± 27.9%, and 72.2.9 ± 20.4%, respectively. Significant differences were observed between NDG and each of the other groups after the training. Changes from pretest were only significant for NDG (P = 0.003). These results suggest that lateral preference among novice judo practitioners during randori can be modulated by the type of practice.
