A Didactic Sequence of Elementary Geometric Optics Informed by History and Philosophy of Science

The concepts and instruments required for the teaching and learning of geometric optics are introduced in the didactic process without a proper didactic transposition. This claim is secured by the ample evidence of both wide- and deep-rooted alternative concepts on the topic. Didactic transposition is a theory that comes from a reflection on the teaching and learning process in mathematics but has been used in other disciplinary fields. It will be used in this work in order to clear up the main obstacles in the teaching-learning process of geometric optics. We proceed to argue that since Newton’s approach to optics, in his Book I of Opticks, is independent of the corpuscular or undulatory nature of light, it is the most suitable for a constructivist learning environment. However, Newton’s theory must be subject to a proper didactic transposition to help overcome the referred alternative concepts. Then is described our didactic transposition in order to create knowledge to be taught using a dialogical process between students’ previous knowledge, history of optics and the desired outcomes on geometrical optics in an elementary pre-service teacher training course. Finally, we use the scheme-facet structure of knowledge both to analyse and discuss our results as well as to illuminate shortcomings that must be addressed in our next stage of the inquiry.     

CICBS: a methodology and a framework for measuring and managing intellectual capital of cities. A practical application in the city of Mataró

The governments of cities have to make important decisions on the future of their communities. In the past, the vision, objectives, and goals of cities have been determined mainly by considering tangible assets as the main factors of a city's prosperity. However, in the knowledge economy, the role of intangible assets in wealth creation has become fundamental. As a result, a framework of intangible assets that allows navigation from the present reality to the future vision has become an urgent need for all cities. The paper has two well-defined parts. In the first part, it develops a specific methodology and framework for measuring and managing the intellectual capital of cities. In the second part, the study deals with the practical application of this model of intellectual capital in cities with the specific case of the city of Mataró, providing some details of the first cities’ intellectual capital report.     

How reflexivity enhances organizational innovativeness: the mediation role of team support for innovation and individual commitment

Reflexivity is a learning process that, through questioning and critically monitoring objectives and methods in use, promotes a change of habits and routines and, in so doing, fosters organizational performance and innovativeness. This paper looks at the contribution of team reflexivity to enhancing openness to innovation, and the mediating role of individual and team involvement. Specifically we tested whether affective commitment (Study 1, n=156) and a team climate of support for innovation (Study 2, n=152) facilitate reflexivity processes in promoting organizational openness to innovation. Overall, results confirmed that reflexivity enhances innovativeness, and this relationship is mediated by a high degree of involvement that increases the motivation of teammates and their engagement in innovation processes.     

Influence of intellectual capital upon knowledge creation in Spanish subsidiaries: an empirical study

Knowledge creation is one of the most important dynamic capabilities that firms can use to develop new assets, which can represent the basis for future innovations. Within a context of growing globalisation, the acquisition and creation of knowledge is one of the main objectives sought with international expansion. The consideration of intellectual capital within the knowledge creation process in subsidiaries offers an innovative way to undertake knowledge management practices in multinationals. Theoretical and empirical works can be found in the literature about intellectual capital. However, very few studies link intellectual capital to knowledge creation in multinationals. Seeking to fill this gap, the purpose of this paper is to develop and test a model that includes the main intangibles belonging to structural and relational capital that can influence knowledge creation in Spanish subsidiaries of foreign multinational firms belonging to high-technology and knowledge-intensive sectors. Theoretical, empirical and managerial contributions result from this paper.     

县级中学高中生物理考试成败归因特点

以435名县级中学高中生为被试,以考试成败归因问卷为工具,旨在探讨高中生对物理考试成败结果的归因特点。研究表明:(1)整体上看,县级中学高中生对物理考试成败倾向于作内部归因,他们将持久努力、临时努力和学习方法等内部可控原因视为首要原因;(2)自我评价成功者与失败者对考试结果的归因存在明显差异;(3)男女生对考试成功的归因不存在明显的差异,对考试失败的归因有一定差异,女生比男生更看重能力、学习方法、学习基础与任务难度等原因对失败结果的影响;(4)高中生对考试成败的归因不存在明显的年级差异。     

Asynchronous and synchronous online teaching: Perspectives of Canadian high school distance education teachers

This paper presents the results of an inductive, interpretive analysis of the perspectives of 42 Canadian high school distance education (DE) teachers on asynchronous and synchronous online teaching. The paper includes a conceptual overview of the affordances and constraints of each form of teaching. Findings provided insight into the following aspects of asynchronous and synchronous online teaching: degree of use; the tools used; the contexts in which each occur; students' preferences; and limitations. Pedagogy emerged as more important than media for both asynchronous and synchronous online teaching. Synchronous online teaching relied on teacher‐ rather than student‐centred approaches. Asynchronous online teaching provided support for self‐paced, highly independent forms of secondary DE supplemented by synchronous online teaching for answering questions and troubleshooting.     

The impact of a peer-tutoring program on quality standards in higher education

The purposes of this study were, on one had, to determine the impact of a peer tutoring program on preventing academic failure and dropouts among first-year students (N = 100), from Civil Engineering, Economics, Pharmacy, and Chemical Engineering careers; while, on the other hand, to identify the potential benefits of such tutoring program on the cognitive and metacognitive learning strategies and social skills of student mentors in their last year of studies or already in a postgraduate program (N = 41) at the University of Granada (Spain). After building and selecting the measurement instruments necessary to gather demographic and academic relevant information on both samples, and assigning first-year students to either an experimental or control group, the intervention consisted of ten 90-min tutoring sessions during the first semester lead by student tutors who, in turn, had undergone four 3-h training sessions on tutoring contents like planning and time management, cognitive and metacognitive learning strategies, motivational strategies and the use of materials designed ad hoc for this program. The results show differences in favour of the treatment group on grade point average, performance rate, success rate and learning strategies and, also, statistically significant pre-post differences for the tutors on learning strategies and social skills.
