CONCEPT MAPPING: AN ALTERNATIVE STRATEGY FOR EVALUATION

Concept maps are proposed as an alternative tool for evaluation in higher education and examples of concept maps, drawn by college students performing evaluation tasks, are presented in the areas of physics and literature.     

Real and perceived employability: a comparison among Italian graduates

The research undertaken for this article aims to analyse the correspondence between perceived employability and the actual national employment rate among Italian students and graduates undertaking different courses in a large Italian university. Data were collected through a cross-sectional survey of 2087 students in 19 faculties, and compared with the national indicators of employment rate for each faculty. Using faculty as unit of analysis, the results indicated a significant correlation between participants’ perceived employability and national employment rate. This trend was similar for both genders. However, the results showed a difference between bachelor’s and master’s degrees: the correlation between perceived and actual employability was not significant among bachelor’s participants while it remained significant among master’s participants. The results suggest that graduates are only partially aware of their possibility to enter the labour market and this, in turn, highlights that universities have only partially met the goal to increase awareness about the chances of finding a job among students and graduates.     

From down house Landlord to Brazilian high school students: What has happened to evolutionary knowledge on the way?

Evolution is considered an essential topic that brings to school a broader perspective of natural phenomena and of the nature of science. Most if not all research has shown that the result of the teaching of evolutionary theories is not positive in different parts of the world. Some have attributed the poor understanding shown by students to teaching style or to students' cognitive abilities. This article reports results of interviews and tests carried out with students after they had been taught the topic of evolution. By adopting a sociocultural perspective, before terming students' views “misconceptions,” attention was given to several different ways Charles Darwin's theories have been re-interpreted by well-known scholars and offered to the public. I have analyzed the approaches taken by Emanuel Radl (1873-1942), John C. Greene, Robert Maxwell Young, and Ernst Mayr to assess the diverse ways Darwinism has been conceived. Attention was also given to the presentation of this controversial knowledge to the public in two major popular books written by respected scientists, Huxley and Kettlewell's Darwin and His World (1975) and Richard Dawkins' more recent The Blind Watchmaker (1989). These analyses revealed remarkable differences between what was written in Downe (Kent) a hundred years ago and what was heard at Sao Paulo (Brazil) nowadays. Students show very poor understanding of evolutionary theories. Their conceptions reveal evolution has been primarily related to the human species. Its meaning is understood as similar to progress, growth, multiplication, and improvement. Biological and cultural evolution are not clearly distinguished. Competition is misunderstood as pure violence, sometimes inevitable, and adaptation is considered an individual process that occurs during the organism's life span. Educational change may not depend just on teaching style and students' cognitive abilities. Modification of factual knowledge and epistemological gaps may be the result of a process of social reconceptualization of knowledge offered to students.     

Drawing a spark from darkness: John Walsh and electric fish

John Walsh's research on electric fish, carried out between 1772 and 1775, proved fundamental for demonstrating that electricity might be involved in animal physiology, and, moreover, in favouring a period of great progress in both the physiology and physics of electrical phenomena. However, Walsh is hardly known to modern neuroscientists and is largely neglected by science historians also. One of the reasons for this neglect is that he never published his 'crucial experiment', that is the production of a spark from a discharge of the electric eel.     

Orphan Works at Theatre Library and Information Centres: Assessing Librarians' Perceptions and Management in Spain

Currently, libraries and other information services are facing new professional challenges in relation to digitization policies and orphan works after the publication of European Directive 2012/28/EU on certain permitted uses of orphan works and Spanish Royal Decree 224/2016. This paper aims to analyse how Spanish library and information centres specialising in theatre and performing arts meet users' textual and non-textual information needs, by respecting copyright issues and being involved in a dynamic and digital environment. For this purpose, an online questionnaire, which was used as a methodological tool, was sent to library directors in February 2018. At the same time, some research questions based on orphan works and digitisation approaches are discussed in the paper, specifically in reference to graphic and audiovisual materials.     

Learning as the Construction and Re-mediation of Activity Systems: Environmental Management in Biogas Production

Abstract

The purpose of this paper is to present theoretical tools for understanding the dynamics of change and learning during the emergence and development of environmental management activities. The methodology consists of a historical analysis of a case of biogas production that took place in the Southwest region of Finland. The theoretical tools used helped to see how the content of an activity guided the historical emergence and change of an EM activity. The practical implication of the paper is that environmental solutions should not be restricted to the adaptation of a system, but should also include the possibility of constructing a new activity, with a new object and means of production. The paper is original in presenting theoretical tools for grasping the content of learning in environmental management activities.     

Comprehensive School Reform in Middle Schools: The Effects of Different Ways of Knowing on Student Achievement in a Large Urban District

Comprehensive school reform (CSR), a federally funded program, is designed to raise student achievement via the implementation of whole school reforms. Unfortunately, although close to 400 CSR models have been adopted by schools nationally, there is relatively limited empirical evidence from rigorous research studies regarding the effectiveness of CSR in general or of specific models in particular. Of additional importance is the extent to which CSR models can demonstrate positive effects over time. The purpose of this study is to evaluate the effects on student achievement and attendance, in an urban school district in Kentucky, of the Year 3 implementation of the Different Ways of Knowing (DWoK) for the Middle Grades model. Results indicated that achievement results on both the Comprehensive Test of Basic Skills and Kentucky Core Content Test were significantly superior for the DWoK schools relative to matched control schools; no positive impacts on student attendance occurred for Year 3. The implications of the study lies in revealing that learner-centered CSR models that integrate the arts with the core curriculum can produce observable achievement gains in both normed- and criterion-referenced tests.     

The scientific investigation for the study and conservation of the wooden model of S. Maria della Consolazione's church (Todi,Italy)

The focus of this work is the wood polychrome model of the church of S. Maria della Consolazione in Todi, an artefact whose author and historical events are not completely known except a general reference to the construction period of the church (1508–1607 AD). In this study, original and additional materials were examined in order to provide a deeper understanding of the painting and assembly techniques, and a greater awareness of how well preserved the object is, as well as an analysis of previous preservation and conservation interventions. The samples from the painted surfaces were examined by means of micro-Raman spectroscopy, fourier transform infrared (FTIR) spectrometry and internal microstratigraphic analysis. Thin sections of the wood samples were examined under an optical transmission light microscope in order to identify the botanical species. The results shown in this paper suggest the possibility that the original painted layers are made of calcium carbonate white, red ochre and indigo and they were applied by protein binder without any ground layer. Some non-original pigments were found on the model surface like Prussian blue and chrome yellow. Concerning wood components, poplar was characterized both in the original and non-original parts of the model whereas pine species were detected only in the restoration elements.
