PLN : The paradigm shift in teacher and learner autonomy

This presentation explains a dozen tools and paradigm shifts that teachers should apply in transformative ways to working with their students, how Web 2.0, tagging, and RSS are crucial to this process, and how teachers can develop their own personal learning networks to practice continuous lifelong learning and 'teacher autonomy' before applying these concepts to students.

Design, development and evaluation of a portable recording system to capture dynamic presentations using the teacher's tablet PC

Computers and multimedia equipment have improved a lot in the last years. They have reduced their cost and size while at the same time increased their capabilities. These improvements allowed us to design and implement a portable recording system that also integrates the teacher´s tablet PC to capture what he/she writes on the slides and all that happens in it. This paper explains this system in detail and the validation of the recordings that we did after using it to record all the lectures the “Communications Software” course in our university. The results show that pupils used the recordings for different purposes and consider them useful for a variety of things, especially after missing a lecture.

Perceptions Surrounding the Implementation of Colorado Senate Bill 10-191's New Teacher Evaluations

In 2013, many public education reform efforts in the United States of America center on testing and accountability. Recent data revealed that teachers have the single greatest in-school impact on student learning; however, the methods to assess teacher effectiveness are widely criticized for not holding teachers accountable and, consequently, are experiencing significant legislative attention. In 2010, Colorado passed Senate Bill 10-191: The Great Teachers and Leaders Act to improve student learning by revising teacher and principal evaluations, including linking them to student learning data, and eradicating tenure. Teachers, administrators, and policymakers hold critical roles in the implementation of this bill, yet little is known about how members of each group perceive their respective roles in the implementation. This explanatory sequential mixed methods study was designed to gather perception data from these three groups, through surveys and interviews. Data revealed that teachers and administrators do not have similar perceptions of many matters related to teacher evaluations, education reform, and the implementation of Senate Bill 10-191 (SB 191). The data also revealed that teachers and administrators expected they would agree on these matters. These collective findings led to multiple recommendations, such as the need for increased dialogue between teachers and administrators about their own perceptions of education reforms.

Don’t Let Me Down: An Autoethnography of an Urban Teacher

Students in urban schools who are negatively impacted need stability and continuity the most. However, at least half of new teachers leave their profession within five years. In order for this situation to change, support is needed for new teachers and encouragement is needed for experienced teachers. The purpose of the study is to offer a first-hand description of factors that affect the profession of teaching and especially teachers who may be wondering how to stay in teaching for more than five years. Veteran teachers gain the opportunity to reflect, validate, and (probably) celebrate their own journey through this profession. This autoethnography uses my experience of a 29-year veteran teacher, who started with an alternative teaching license, to mirror what researchers have identified as key factors for sustainability and how they affected my continued commitment to teaching in urban schools. The following questions framed the study: 1. Why did I choose teaching as a career? 2. What supportive factors contributed to my decision to continue teaching in an urban school rather than leave the profession? 3. What internal and external struggles have I encountered in teaching and what strategies did I use to overcome them? 4. What beliefs and experiences led to my steadfast commitment to teaching in an urban setting? 5. How do I define success as an urban teacher? 6. What are the implications of my story for urban education? This autoethnography involves data collection and in-depth analysis of documents and artifacts that were generated during my teaching career as an urban educator. These documents and artifacts come from both internal and external sources. The study’s implications reach beyond teachers and include two sub-groups: teacher education programs and school administrators. The implication for teachers is the importance of a two-fold support system in order to thrive: first teachers need spiritual support and second they need to surround themselves with likeminded teachers. The implications for teacher education programs include making pre-service teachers aware of the realities of urban settings and provide them with resources, which could help overcome the attrition rate. Additionally, pre-service teachers need to know how to form credible relationships with their students. This study also reveals the important role that school principals play in the success of their teachers. First, principals are responsible for creating a positive school climate that promotes a professional learning community. Second, they need to establish relational trust in their building. Third, they need to nourish their staff both physically and emotionally. Finally, the implications of autoethnography for teachers and researchers are also discussed.

Development and psychometric testing of the clinical learning environment, supervision and nurse teacher evaluation scale (CLES+T): The Spanish version

Background: The Clinical Learning Environment, Supervision and Nurse Teacher scale is a reliable and valid instrument to evaluate the quality of the clinical learning process in international nursing education contexts. Objectives: This paper reports the development and psychometric testing of the Spanish version of the Clinical Learning Environment, Supervision and Nurse Teacher scale. Design: Cross-sectional validation study of the scale. Setting: 10 public and private hospitals in the Alicante area, and the Faculty of Health Sciences (University of Alicante, Spain). Participants: 370 student nurses on clinical placement (January 2011–March 2012). Methods: The Clinical Learning Environment, Supervision and Nurse Teacher scale was translated using the modified direct translation method. Statistical analyses were performed using PASW Statistics 18 and AMOS 18.0.0 software. A multivariate analysis was conducted in order to assess construct validity. Cronbach’s alpha coefficient was used to evaluate instrument reliability. Results: An exploratory factorial analysis identified the five dimensions from the original version, and explained 66.4% of the variance. Confirmatory factor analysis supported the factor structure of the Spanish version of the instrument. Cronbach’s alpha coefficient for the scale was .95, ranging from .80 to .97 for the subscales. Conclusion: This version of the Clinical Learning Environment, Supervision and Nurse Teacher scale instrument showed acceptable psychometric properties for use as an assessment scale in Spanish-speaking countries.

New galactic star clusters discovered in the VVV survey. Candidates projected on the inner disk and bulge

Context. VISTA Variables in the Vía Láctea (VVV) is one of six ESO Public Surveys using the 4 meter Visible and Infrared Survey Telescope for Astronomy (VISTA). The VVV survey covers the Milky Way bulge and an adjacent section of the disk, and one of the principal objectives is to search for new star clusters within previously unreachable obscured parts of the Galaxy. Aims. The primary motivation behind this work is to discover and analyze obscured star clusters in the direction of the inner Galactic disk and bulge. Methods. Regions of the inner disk and bulge covered by the VVV survey were visually inspected using composite JHKS color images to select new cluster candidates on the basis of apparent overdensities. DR1, DR2, CASU, and point spread function photometry of 10 × 10 arcmin fields centered on each candidate cluster were used to construct color–magnitude and color–color diagrams. Follow-up spectroscopy of the brightest members of several cluster candidates was obtained in order to clarify their nature. Results. We report the discovery of 58 new infrared cluster candidates. Fundamental parameters such as age, distance, and metallicity were determined for 20 of the most populous clusters.

Micro/Mesoporous Activated Carbons Derived from Polyaniline: Promising Candidates for CO2 Adsorption

A series of activated carbons were prepared by carbonization of polyaniline at different temperatures, using KOH or K2CO3 as activating agent. Pure microporous or micro/mesoporous activated carbons were obtained depending on the preparation conditions. Carbonization temperature has been proven to be a key parameter to define the textural properties of the carbon when using KOH. Low carbonization temperatures (400–650 °C) yield materials with a highly developed micro- and mesoporous structure, whereas high temperatures (800 °C) yield microporous carbons. Some of the materials prepared using KOH exhibit a BET surface area superior to 4000 m2/g, with total pore volume exceeding 2.5 cm3/g, which are among the largest found for activated carbons. On the other hand, microporous materials are obtained when using K2CO3, independently of carbonization temperature. Some of the materials were tested for CO2 capture due to their high microporosity and N content. The adsorption capacity for CO2 at atmospheric pressure and 0 °C achieves a value of ∼7.6 mmol CO2/g, which is among the largest reported in the literature. This study provides guidelines for the design of activated carbons with a proper N/C ratio for CO2 capture at atmospheric pressure.

Evaluation of the Implementation of CLIL (Content and Language Integrated Learning) Methodology in the Didactics of the English Language in Preschool Education Course Taught in the Preschool Education Teacher Undergraduate Program at the University of Alicante

Although it is known that the Spanish current Educative System promotes using the Communicate Approach to teach foreign languages in schools, other recently designed approaches are also used to help students improve their skills when communicating in a foreign language. One of these approaches is Content and Language Integrated Learning, also known as CLIL, which is used to teach content courses using the English language as the language of instruction. This approach improves the students’ skills in English as the same time as they learn content from other areas. The goal of this thesis is to present a research project carried out at the University of Alicante during the academic year 2011-2012. With this research we obtained results that provide quantitative and qualitative data which explains how the use of the CLIL methodology affects the English level of students in the “Didactics of the English Language in Preschool Education” course in Preschool Education Teacher Undergraduate Program as students acquire the contents of the course.

Identifying student and teacher difficulties in interpreting atomic spectra using a quantum model of emission and absorption of radiation

Our study sets out to identify the difficulties that high school students, teachers, and university students encounter when trying to explain atomic spectra. To do so, we identify the key concepts that any quantum model for the emission and absorption of electromagnetic radiation must include to account for the gas spectra and we then design two questionnaires, one for teachers and the other for students. By analyzing the responses, we conclude that (i) teachers lack a quantum model for the emission and absorption of electromagnetic radiation capable of explaining the spectra, (ii) teachers and students share the same difficulties, and (iii) these difficulties concern the model of the atom, the model of radiation, and the model of the interaction between them.
