Reflective teaching: theory within classroom practices

The core of the Senate Bill 2042 (1998) was designed to provide the guidelines needed to prepare teachers who can meet the needs of a diverse K-12 student population in California. Following the guidelines marked by this bill, faculty working in Teacher Credential Programs across California are designing activities to prepare candidates with a deep understanding of effective pedagogies applicable to a full range of students. A key component in this preparation is to provide teacher candidates with opportunities to critically read and reflect on theory and research. Understanding the importance of this component, I designed an assignment, Quadruple Entry Journals (QEJ), which asks teacher candidates to first, critically read texts on theory; secondly, to reflect and analyze those texts; thirdly, to reflect on the reflections of their classmates; and, finally, to connect these theoretical reflections with practice. In this article, I explain the pedagogy followed when implementing QEJ with teacher candidates. Their feedback showed that when theory and research are cooperatively analyzed by teacher candidates, they better understand the connection between theory and practice, thus creating a deep understanding of what to teach and how to teach.     

A collaborative filtering similarity measure based on singularities

Recommender systems play an important role in reducing the negative impact of information overload on those websites where users have the possibility of voting for their preferences on items. The most normal technique for dealing with the recommendation mechanism is to use collaborative filtering, in which it is essential to discover the most similar users to whom you desire to make recommendations. The hypothesis of this paper is that the results obtained by applying traditional similarities measures can be improved by taking contextual information, drawn from the entire body of users, and using it to calculate the singularity which exists, for each item, in the votes cast by each pair of users that you wish to compare. As such, the greater the measure of singularity result between the votes cast by two given users, the greater the impact this will have on the similarity. The results, tested on the Movielens, Netflix and FilmAffinity databases, corroborate the excellent behaviour of the singularity measure proposed.     

Raman mapping analysis of pigments from Proas Iluminadas by Quinquela Martín

The painting Proas Iluminadas (Illuminated Bows) by Benito Quinquela Martín is studied by Raman spectroscopy in order to analyse the technique and the pigments employed by the artist: ultramarine blue, carbon black, cadmium-sulphure based compounds for the hue of yellow, orange and red; also zinc white, barium yellow, massicot yellow and viridian were observed. The importance of using different excitation laser lines in the analysis of mixtures of pigments is highlighted. The Raman mapping analysis of cross section samples shows the way the artist composed the ground layer: a lead white stratum over a calcite one. It also allows distinguishing between a mixture of components and strata superposition, both presenting the same appearance under an optical microscope. This paper provides information about the materials and techniques used in a period of Argentine art not studied before from this point of view.     

Results of a Pilot Study to Investigate Community College Student Perceptions of the Value of an Online Health-Risk Reduction Program

Health is associated with academic success. Universal, web-based interventions to reduce risks associated with alcohol and other drug use have been found to be effective at changing four-year college students’ health behaviors. An online health program may also be well-suited to a community college population, as it can reach students off campus and can be accessed at times that are convenient for students. The purpose of the current paper is to report the results of a community college student evaluation of a fully-developed, online health risk reduction program. One hundred and thirty four students evaluated the program. Students perceived the program to be successful at addressing college health and wellness issues, and they considered it a tool that could help students make a healthy adjustment to college. A universal, online, health-risk reduction program may have the potential to be a useful component of a community college's overall prevention strategy.     

Agents control in intelligent learning systems: The case of reactive characteristics

Intelligent learning systems (ILSs) have evolved in the last few years basically because of influences received from multi-agent architectures (MAs). Conflict resolution among agents has been a very important problem for multi-agent systems, with specific features in the case of ILSs. The literature shows that ILSs with cognitive or pedagogical agents are prone to arbitration methods, where as ILSs with reactive agents are much in favor of control mechanisms. For these kind of systems, different control types are proposed based on the different stimuli that these agents will receive. These stimuli are aspects to be evaluated during the teaching/learning process such as: (1) error analysis, (2) learning styles, (3) analogies, (4) social aspects, etc.

The paper reviews several ILSs, related to our work; different control mechanisms are proposed to solve the agents' intervention conflicts. Finally, the use of several mechanisms is exemplified by the results of a specific ILS.     

The relationship between teacher’s autonomy support and students’ autonomy and vitality

Abstract

Within education, some teachers’ interpretation of professionalism emphasizes conformity to the perceived norms of collective associations. Unprofessional behaviour, often equated with ‘unethical’ behaviour, is seen by many to be that which threatens solidarity and loyalty to colleagues. Informal norms typified by casual collegial relations as well as more formal attachments to organized unions or teachers’ federations exert a significant influence on individuals’ behaviour within the group. Professional ethics, in this sense, become concerned primarily with how one relates to colleagues rather than how one fulfils moral responsibilities to students. Qualitative findings from interviews with elementary and secondary school teachers suggest that, as a result of an ethic of collegial loyalty, some teachers experience personal moral and ethical dilemmas that they find difficult to resolve. Some respondents acknowledged that this can enable serious situations to be ignored or ‘covered up’. This paper examines some of the tensions and dilemmas experienced by teachers and raises questions about the ethical adequacy of defining professionalism in terms of inter‐colleague behaviour.     

Teaching and learning across disciplines: student and staff experiences in a newly modularised system

Within modular degrees it is sometimes possible for students to broaden their education by taking modules from outside their main programme of study. This is one significant aspect of modular degrees which has not been studied. In an effort to better understand this issue, the research reported in this paper explored the experiences: (1) of students taking modules from outside their programme of study and; (2) of staff teaching modules with significant numbers of students from other programmes. In total, 820 undergraduate students responded to an on-line survey; 12 academic staff members participated in interviews. The survey focused on students’ reasons for choosing the module, their experiences of assessment and their perceptions of workload. Interviews with academic staff focused on the influence of non-programme students on teaching and assessment practices. The discussion addresses the implications of student choice and classroom diversity for teaching and assessment in modular systems.
