Movilizar la enseñanza de ELE para aumentar la participación espontánea: estudio de caso con alumnos universitarios tailandeses. Mobilizing the teaching and learning of Spanish as a foreign language to raise spontaneous participation: A case study of Thai university students. doi 10.20420/ElGuiniguada.2018.206

Abstract: El objetivo de este articulo es presentar los resultados preliminares sobre el impacto del uso de dispositivos moviles en la participacion y motivacion de un grupo de ciento veintidos estudiantes de espanol de nivel A1 de una universidad publica tailandesa. Partimos de la premisa de que las caracteristicas socioculturales propias de este contexto impactan en el proceso de ensenanza y aprendizaje, puesto que influyen en la interaccion entre los discentes, en la forma de relacionarse con el docente y con los contenidos curriculares, por lo que consideramos que pueden ser responsables de las rutinas de participacion de los integrantes del grupo que aprende la lengua meta. Para modificar la influencia del contexto proponemos la inclusion de dispositivos moviles con el fin de disminuir el estres que el alumnado sufre al participar en el aula y aumentar la participacion espontanea en las actividades didacticas de clase. Este articulo describe las caracteristicas de esta investigacion y los resultados obtenidos.

Recent Development in Alkynol Chemistry: Electrophilic Iodonium-Induced Rearrangements

Abstract: Recent development in iodonium-induced reactions of alkynols is discussed and analysed herein. ClassicalMeyer-Schuster and Rupe rearrangements are described as a background to the main body of iodonium-inducedreactions. α-Iodoenones derived from rearrangement of alkynols, known herein as the Iodo Meyer-Schusterreaction, links the classical Meyer-Schuster reaction to the novel reaction of iodonium-induced rearrangement ofalkynols. The rearrangements leading to the formations of β-haloenones and β,β-dihaloenones and enals arediscussed with mechanistic considerations, which include stereospecificity of the migrating group and themigratory aptitude differences between the phenyl and the alkyl groups. The role of solvents – namely the watercontent in organic solvent – is presented with mechanistic consideration of the role of the allenol, the haloniumbridge cation intermediates and water in dictating each different reaction pathways. The application of therearrangement reaction to biological interesting molecules such as glucofuranose and xylofuranose is discussed.Haloetherification reaction, the third type of halonium-induced alkynol reaction, was found to be the exclusivereaction in the halogenation of alkynol derivative of hexofuranoses. Key Words: Electrophilic halogenations; Alkynols; Iodonium ions; Meyer-Schuster and Rupe Rearrangements;β-Haloenones; β,β-Dihaloenones and enals; Ring expansion of alkynols

Thai Consumers’ Willingness to Pay for Different Front-of-Package Nutrition Labels

Abstract: This research study focuses on the willingness to pay for food products that have different front-of-package (FOP) nutrition labels, namely include the monochrome Guideline Daily Amounts (GDA) label, the colorcoded GDA label, and the traffic light label. While there has been a proposal to adopt the traffic light label, Thailand’s Ministry of Public Health currently requires five types of snacks to display the monochrome GDA label. The nth price auction was the method employed in this experiment to elicit the willingness to pay from seventy two Thai consumers. The participants had to bid for two types of seaweed and two types of almonds, affixed with three different types of FOP labels or a plain label. The grilled and fried seaweeds contain different amounts of fat, whilst the unsalted and salted almonds contain different levels of sodium. The results show that all of the FOP labels, including the monochrome GDA label, add price premiums to both healthy and unhealthy foods. The traffic light label is effective in influencing consumers’ demand, since consumers are willing to pay higher prices for healthier products. In addition, participants were also divided into two groups, after providing one group with additional information about the meanings of the different FOP labels. Under the traffic light label, the group provided with the extra information gave higher valuations on healthier foods.

A quantitative study on average number of spins of two-player Dreidel

Abstract: We give a high precision approximation of the average number of spins in a simplified version of a two-player version of the game Dreidel. We also make a conjecture on the average number of spins o...

Reflecting the teacher’s role in a project-based learning (pbl) classroom: lessons learned from students

Abstract: This study aimed to investigate students’ expectations for teachers using project-based learning (PBL) in an individual classroom, from a tactical perspective, based upon students’ perceptions toward 1) topic choice, 2) teacher’s support, 3) evaluation method, and 4) preference for PBL. The Kano model, commonly used to compare the service expectations and performance perceptions of customers in a marketing context, was adopted as the survey instrument to evaluate 152 students’ perceptions. The results of the study were as follows. 1) From a tactical level, when conducting PBL, teachers should decide the project topic and evaluation method, and must provide sufficient and detailed assistance to students regarding the project. 2) From a more conceptual level, teachers’ domination in areas that are beyond the students’ capabilities to make decisions, greatly contributes to students’ learning.
