"Amapolita morada". Identidad mexicana silvestre y melancólica
Authors: Blancas Blancas Noé 
Published: April 2018

La copla "Amapolita morada" constituyó el motivo para la creación del poema "Glosa de mi tierra" de Alfonso Reyes y de la canción de Las mañanitas de Manuel M. Ponce. En ambas obras, poeta y músico dejan testimonio de una las preocupaciones del grupo al que pertenecieron, El Ateneo de la Juventud. Flor silvestre y callada, veros de queja, la amapola es un sómbolo de lo sinvestre en el poema de Reyes. Joven que despierta entre el arrullo de lentas campanadas y cantos de pájaros en una mañana pueblerina, la flor constituye una imagen de la melancolía para Manuel M. Ponce. Lo silvetsre y lo melancólico son las características que ambos mexicanos consideran esenciales del alma mexicana.

Published: April 2018

AbstractThe polyanion polystyrene sulfonate (PSS), the polycation poly (allylamine hydrochloride) (PAH), and the anionic poly (N-isopropylacrylamide-co-acrylic acid) [P(NIPAM-co-AA)] microgels were self-assembled onto the polyethylene imine (PEI) adsorbed gold surfaces of quartz crystal microbalance (QCM) because of the electrostatic attractions. The interactions of various metal particles including Ca2+, Bi3+, Cu2+, Zn2+, Ni2+, Sn2+, Co2+, and Cd2+with the obtained PEI/PSS/PAH/microgel layer in aqueous solutions were evaluated by QCM. The PEI/PSS/PAH/Microgel covered QCM sensor demonstrates the lowest detection limit of 0.1 ppm in aqueous solutions and the obviously linear connection between the frequency response and Ni2+concentration from 0.1 to 20 ppm, which is due to the complexation of Ni2+with the carboxyl groups of microgels. Atomic force microscopy (AFM) was used to reveal the morphology and stability of the self-assembled polyelectrolyte/microgel layer before and after adsorbing heavy metal ions. These self-assembled materials of polyelectrolyte/microgel layer will be helpful for manufacturing ion-selective materials for separation and identification purposes.
Pengembangan Kompetensi Profesional Guru dalam Menghadapi Sertifikasi

Published: April 2018

Certification of teacher have been accounted for as one of the education core reforms to improve teacher professionalism. The release of the Act No. 14/ 2006 for Teacher and Lecturer (atÂ higher education) is noticeable to be a historical tombstone which sets teacher and lecturer as profession as well as doctor, engineer or others. This will change the public perception to teacher to become more positive, to build up the teacher self-confident, and to magnetize the interest of those first quality candidates to turn out to be teachers, and to give the public trust back to school as an educational institution. It isÂ highly recommended that the enhancement of teacher professional capacity to be integrated with the instructional activities implemented at schools, which, on one hand are capable of improving their quality of teaching as teachers, on the other hand capable of giving them the opportunities to improve their professional capacity while toting-up their cummulative credits mandatory for teacher certification.Â ABSTRAKSertifikasi guru dinilai sebagai salah satu kebijakan reformasi pendidikan untuk meningkatkan profesionalisme guru. Keluarnya Undang-Undang Nomor 14/2006 tentang Guru dan Dosen adalah merupakan tonggak sejarah tentang bagaimana guru dan dosen diakui sejajar sebagai pekerja profesi sebagaimana pula dokter, insinyur, atau profesi lainnya. Hal ini akan mengubah opini publik terhadap guru menjadi semakin positif, selain juga akan meningkatkan kepercayaan diri mereka, juga akan menarik minat orang-orang yang potensial dan berkualitas untuk menjadi guru, serta mengembalikan kepercayaan masyarakat kepada sekolah sebagai lembaga pendidikan yang berwibawa. Berdasarkan elaborasi aspek aspek profesi guru, sangat disarankan bahwa peningkatan kemampuan profesional guru merupakan kegiatan yang terintegrasi dengan kegiatan pembelajaran di sekolah, satu sisi mampu meningkatkan kualitas mengajar mereka sebagai guru, di sisi lain dapat memberi peluang bagi mereka meningkatkan kemampuan profesional sekaligus menambah kredit akumulatif mereka untuk kepentingan sertifikasi.

Ethesami and Abrahamian named Iran Pst Khomeini as the Second Republic with a different reason. While Halliday name it with post-achundism. This paper is conduxted to show dialectic of religion and politics that goes rationally, so it can be used as the reflectionfor Moeslem in Indonesia. This paper used a multidimensional historical approach in order to get a complete view. This approach is expected to accomodate both of Enthesami view which focus on economic aspectsm and Abrahamian view which focus on cultural aspects, also Halliday view which saw the involvement of clerics in politics. The modification of Islamic system of government of Iran post Khomeini can not be separated from the basics of the changes that have been placed by Khomeini.Â ABSTRAKEhthesami dan Abrahamian menamakan Iran Pasca Khomeini sebagai the Second Republic dengan alasan yang berbeda. Sedangkan Halliday menamainya dengan post-akhundism. Tulisan ini ingin menampilkan dialektika agama dan politik yang berlangsung secara rasional, agar bisa dijadikan cermin bagi umat Islam di Indonesia. Tulisan ini menggunakan pendekatan sejarah multidimensional agar didapat pandangan yang lebih utuh. Pendekatan ini diharapkan dapat menampung baik pandangan Ehthesami yang lebih menekankan pada aspek ekonomi, dan pandangan Abrahamian yang lebih menekankan pada aspek budaya, maupun pandangan Halliday yang melihat keterlibatan ulama dalam politik. Modifikasi sistem pemerintahan Islam Iran pasca Khomeini tidak dapat dilepaskan dari dasar dasar perubahan yang telah diletakkan oleh Khomeini.

Una educación inclusiva promueve el acceso equitativo y la permanencia de los estudiantes con el fin de garantizar igualdad de oportunidades para todos. Las implementaciones pueden estar basadas tanto en estudios como en prácticas empíricas, y se enfocan principalmente desde tres aspectos: lo físico, lo cognitivo y lo social. Es así, como se hace relevante identificar y analizar casos exitosos y mejores prácticas realizadas por las instituciones educativas colombianas. De igual manera, dados los avances tecnológicos, es imperativo lograr una fusión entre la tecnología y la inclusión con el fin de llegar al objetivo deseado.
Determination of the Size and Depth of Craters on the Moon
Authors: Grubelnik Vladimir , Marhl Marko , Repnik Robert 
Published: April 2018

Experimental work in the research of astronomical phenomena is often difficult or even impossible because of long-lasting processes or too distant objects and correspondingly too expensive equipment. In this paper, we present an example of observation of the Moon, which is our nearest astronomic object and therefore does not require professional astronomic equipment for observation. We focus on the observation of craters on the Moon, determining their lateral size and depth on the basis of photographs and simple calculations. The fieldwork with students of junior grade school education was performed within the framework of the optional subject Astronomy. An analysis of the results of the students’ experimental work, as well as of curricula on various levels of education, led us to conclusion that this kind of experimental work is suitable for incorporation in secondary school physics education. With some mathematical simplifications, however, the treatment of the topic can also be appropriate in primary school. Such experimental work enables students to gain specific natural science and mathematical competences that are also required for the study of other natural phenomena.
Professionalising Physics Teachers in Doing Experimental Work
Authors: Haagen-Schützenhöfer Claudia , Joham Birgit 
Published: April 2018

It is commonly agreed that experiments play a central role in teaching and learning physics. Recently, Inquiry-Based Learning (IBL) has been introduced into science teaching in many countries, thus giving another boostfor experiments. From a didactical point of view, experiments can serve a number of different goals in teaching and learning physics. First of all, experiments can support learners in understanding some of the centralconcepts of physics. Besides this function of “learning physics”, empirical evidence shows that experimental work in general has a high potential for promoting “learning about science” and finally “doing science”. Promoting aspects of how science works has become important, as the ideas of scientific literacy and competence orientation have been established as central educational goals in many national education systems. However, empirical studies show that the reality in schools does not match these expectations. Conventional physics classes still aim only at the mastery of content, and experiments that cognitively activate students and address issues related to the Nature of Science (NOS) have not been implemented extensively. The reasons for this can be found in teachers’ attitudes and beliefs, as well as in their PCK concerning experiments and scientific knowledge production. In past decades in Austria, teacher education did not focus a great deal on the didactical aspects of experiments or their integration into physics classes in order to promote aspects of scientific literacy and competence orientation. Furthermore, there is a lack of high quality continuing professional development courses that promote the concepts of Inquiry-Based Learning (IBL) in combination with relevant ideas of NOS. The present study examines inservice teachers’ beliefs about the function of experiments in science teaching and their meaningful integration into science classes. In the form of case studies, we follow the professional development of teachers in this field during continuing teacher training.
Taxonomy of Teaching Methods and Teaching Forms for Youth in Non-Formal Education in the National Youth Council of Slovenia
Authors: Miloševič Zupančič Vesna 
Published: April 2018

Research from the field of non-formal education (NFE) in youth work emphasises the central role of experiential learning and learning in groups. The present paper aims to research teaching methods and teaching formsin NFE in youth work. The research sought to answer the following research questions: ‘What teaching forms can be found in NFE for young people in youth councils on a national level in Slovenia?’ and ‘What teachingmethods can be found in NFE for young people in youth councils on a national level in Slovenia?’ Data was collected using semi-structured interviews; the instrument was a list of questions. The empirical research was conducted in July 2016 with six interviewees. The results indicate that learning in selected NFE in the National Youth Council of Slovenia (MSS) is participatory, interactive, inclusive and student-focused; with central concepts of experiential learning and learning in groups. The key teaching form is learning in groups. However, individual work, work in pairs, programmed instruction and direct instruction are also present. The central and omnipresent teaching method is experiential learning. Problem-based learning, case-study method, action learning, and project-based learning are intertwined and connected to the experiential learning method. Other methods include verbal-textual methods, illustrative-demonstration methods, experimental methods, peer learning, and support methods. The conclusions are applicative in the didactic spectrum of NFE in youthwork and in the wider didactic spectrum of adult learning. Implications for further research include teaching methods and forms in NFE inside the wider youth sector, internationally comparative and through quantitativeresearch.
Teaching and Learning Vocabulary: What English Language Learners Perceive to Be Effective and Ineffective Strategies
Authors: Tamimi Sa’d Seyyed Hatam , Rajabi Fereshte 
Published: April 2018

Vocabulary constitutes an essential part of every language-learning endeavour and deserves scholarly attention. The objective of the present study was three-fold: 1) exploring Iranian English language learners’Vocabulary Learning Strategies (VLSs), 2) examining language learners’ perceptions of vocabulary learning, and 3) exploring Iranian English language teachers’ Vocabulary Teaching Strategies (VTSs). In total, 145 intermediate learners of English as a foreign language, consisting of 114 males and 31 females aged 15 to 27, participated in the study. The triangulated data were collected using three tools: questionnaires, interviews, and class observations. Sixty-seven learners (31 females and 36 males) filled out a 56-statement questionnaire, adopted and adapted from Takač (2008) and translated into Persian. The questionnaire comprised two parts, enquiring as to the learners’ VLSs and the teachers’ VTSs. The findings indicated that females and males differed significantly in their reported VLSs and their teachers’ use of various VTSs. Additionally, 78 learners were interviewed as to their perceptions of effective and ineffective VLSs as well as VTSs. The findings revealed that the most effective VLSs were reported to be: a) reciting, repeating and listening to words, b) using words, and c) memorising words while the most effective VTSs revolved around: a) explanation, b) repetition, and c) dictation. The observations also confirmed the findings obtained via the questionnaire and interviews. In general, the findings are indicative of the limited repertoire of vocabulary acquisition techniques employed by Iranian EFL learners, hence the need for strategy training in how to acquire vocabulary.

Alloying Factors and Parameter of Alloying Elements for Carbon and Nitrogen Uptake during Carbonitriding as Basis for Simulation
Authors: Skalecki M. G. , Klümper-Westkamp H. , Steinbacher M. , Zoch H.-W. 
Published: April 2018

Abstract
Carbonitriding serves to increase the strength and wear properties of steel components. The carbon and nitrogen concentration and the depth distribution decisively determine the resulting properties. Optimal profiles create an ideal microstructure of martensite, residual austenite, finely distributed nitrides, carbonitrides and inherent compressive stress in the surface zone. The reliability of carbonitriding heat treatment process is strongly dependent on the possibilities of process control. Previous investigations aimed at measuring the nitrogen potential of the atmosphere by means of an ammonia sensor in the exhaust gas as well as by a wire sensor. Carbon potential is conventionally controlled using an oxygen probe. In order to further increase the process reliability of carbonitriding, simulation of the carbon and nitrogen profiles and of any precipitation of carbides and nitrides are necessary. The first step is the determination of interdependent alloying influences on the carbon and nitrogen contents. The carbon and nitrogen activities in the atmosphere and the alloy surface are near equilibrium after long-time carbonitriding. Depending on the composition of the material, significantly different effects can be described. These influences must be considered. In addition to the reached equilibrium content, the diffusion, the position of phase boundaries in the phase diagrams and the formation of precipitation with influence of carbon and nitrogen as well as interactions with other alloying elements are to be worked out in order to further develop controlled carbonitriding for the reliable adjustment of the heat treatment results.
