<body><![CDATA[<p align="justify"><font face="verdana" size="2"><i>Felicidades, por el XV Aniversario de Relime, les deseo a todos aquellos colegas que de un modo u otro han colaborado para que esta revista se haya convertido en un referente de la investigaci&oacute;n en Matem&aacute;tica Educativa.</i></font></p>  		    <p align="right"><font face="verdana" size="2">Juan Antonio Alan&iacute;s, Instituto Tecnol&oacute;gico y de Estudios Superiores de Monterrey, MEXICO</font></p> 	</blockquote>  	    <p align="justify"><font face="verdana" size="2">Adicionalmente se constituyeron grupos de trabajo con programas de investigaci&oacute;n muy claros y de naturaleza emergente. El de "profesionalizaci&oacute;n docente en matem&aacute;ticas" se conform&oacute; con la participaci&oacute;n de varias decenas de miembros institucionales y con el impulso de las colegas Martha Jarero (Universidad Aut&oacute;noma de Yucat&aacute;n) y Elizabeth Mariscal (Instituto Polit&eacute;cnico Nacional). En este sentido, cabe se&ntilde;alar una singular coincidencia de la que queremos ocuparnos enseguida: pues en el a&ntilde;o 2013, muy recientemente, fue publicado por Springer el libro panor&aacute;mico de investigaci&oacute;n en Matem&aacute;tica Educativa en su serie "Springer International Handbooks of Education 27, DOI 10.1007/978&#45;1&#45;4614&#45;4684&#45;2_11, New York : USA". Libro titulado <i>Third International Handbook of Mathematicas Education</i> editado por M. A. Clements et al. Los conocidos <i>Handbooks</i> ponen al d&iacute;a la investigaci&oacute;n contempor&aacute;nea en el mundo entero en una tem&aacute;tica particular, si bien mayormente centrados en la investigaci&oacute;n de tradici&oacute;n anglosajona.</font></p>  	    <p align="justify"><font face="verdana" size="2">Desde nuestro punto de vista, el Cap&iacute;tulo 11, titulado: Research Methods in Mathematics Teacher Education, escrito por Uwe Gellert (Freie Universit&auml;t Berlin, Berlin, Alemania), Rosa Becerra Hern&aacute;ndez (Universidad Pedag&oacute;gica Experimental Libertador, Caracas , Venezuela), y Olive Chapman (University of Calgary, Calgary, Canad&aacute;) presenta una muy interesante reflexi&oacute;n sobre un asunto de la mayor importancia para la comunidad de educadores iberoamericanos en Matem&aacute;tica Educativa: La cuesti&oacute;n metodol&oacute;gica.</font></p>  	    <blockquote> 		    <p align="justify"><font face="verdana" size="2">En su resumen declaran:</font></p>  		    <p align="justify"><font face="verdana" size="2">ABSTRACT</font></p>  		    <p align="justify"><font face="verdana" size="2">As the field of mathematics education grows so too do the research methods used to study the field. In the special area of teacher education, the last decade has witnessed a substantial increase in attention. New perspectives and new methodologies have been constituted and new research techniques established. Choosing the "right" method is not a trivial task for any researcher, and increasingly we are seeing more sophisticated research methods, including different forms of mixed methods.</font></p>  		    <p align="justify"><font face="verdana" size="2">A main concern of research these days relates to the fact that as well as studying teachers and teaching, researchers want to see their findings applied to the professional development of teachers and to a critical modification of teacher education practices, in the frame of social changes. This has led to more research with teachers rather than on teachers. After surveying state&#45;of&#45;the&#45;art of methods in research on mathematics teacher education published in renowned international journals, this chapter focusses on participatory action research as an example of a research method from the politicized periphery of the field (Gellert, Becerra &amp; Chapman, 2013, p. 327).</font></p> 	</blockquote>  	    <p align="justify"><font face="verdana" size="2">En este cap&iacute;tulo del Handbook se indica que con anterioridad a 1998, fecha de la aparici&oacute;n del <i>Journal of Mathematics Teacher Education</i> (JMTE), no hab&iacute;a demasiados estudios sobre profesionalizaci&oacute;n docente en el campo de las matem&aacute;ticas. Se&ntilde;alan tambi&eacute;n que esto fue reconocido en la encuesta impulsada por Lubienski y Bowen en 2000, quienes analizando 48 de las principales revistas de educaci&oacute;n entre 1982 y 1998, encontraron que s&oacute;lo 6% de 3011 art&iacute;culos abordaban la educaci&oacute;n de los maestros. Esta situaci&oacute;n cambi&oacute; sustancialmente a partir de entonces, pues en un reporte realizado por Ana Sfard en 2005, al momento de resumir una encuesta llevada a cabo en el ICME &#45; 10 en Dinamarca, ella pregunt&oacute; a 74 participantes c&oacute;mo podr&iacute;an describir su trabajo en Matem&aacute;tica Educativa en los &uacute;ltimos cinco a&ntilde;os, de ah&iacute; obtuvo que dos terceras partes de los encuestados podr&iacute;an tener una centraci&oacute;n en la pr&aacute;ctica del profesor de matem&aacute;ticas. Esto aun cuando una gran cantidad de investigadores se ocupan total o parcialmente sobre la profesionalizaci&oacute;n docente, no se ten&iacute;an investigaciones sobre el tema. Este hecho fue tambi&eacute;n se&ntilde;alado durante el ICME &#45; 11, el grupo sobre <i>Research on Classroom Practice</i> (Brousseau, Caba&ntilde;as, Cantoral, DaPonte, Lezama &amp; Lin, 2009), plante&oacute; que el tema a&uacute;n no hab&iacute;a sido del todo tratado con la profundidad requerida. Ambos reportes se&ntilde;alan, inequ&iacute;vocamente, que se trata de una tendencia emergente y sobre la cual habr&aacute; que ocuparnos en <i>Relime.</i></font></p>  	    ]]></body>
<body><![CDATA[<p align="justify"><font face="verdana" size="2">Por lo anterior, decidimos continuar la reflexi&oacute;n de estos autores iniciada en el Topic Study Group &#45; TSG 24, del ICME 11 y revisar a la propia <i>Relime</i> a este respecto, pues si bien los asuntos sobre profesionalizaci&oacute;n docente en matem&aacute;ticas est&aacute;n creciendo considerablemente, no hay una explicitaci&oacute;n compartida sobre los m&eacute;todos de investigaci&oacute;n empleados para esos fines. Ahora bien, en esta editorial, queremos mostrar las observaciones se&ntilde;aladas recientemente en el <i>Handbook of Mathematics Teacher Education</i> tanto en la tradici&oacute;n anglosajona como latinoamericana:</font></p>  	    <blockquote> 		    <p align="justify"><font face="verdana" size="2">Although the field of research on mathematics teacher education has grown substantially and continues to grow, "research method" seems to be a peripheral aspect of this research. As a prominent example, the four volumes of The International Handbook of Mathematics Teacher Education (Jaworski &amp; Wood, 2008; Krainer &amp; Wood, 2008; Sullivan &amp; Wood, 2008; Tirosh &amp; Wood, 2008) were organized along the questions of the what, the how and the who of mathematics teacher education as well as on the knowledge and roles of teacher educators working with teachers in teacher education processes and practices. However, there was no explicit focus on the methods by which all that knowledge of mathematics teacher education had been accumulated in any of the 60 chapters. A similar absence can be observed in an editorial of JMTE in which the three articles of the issue were introduced with the words: "These three articles differ in many aspects, including scope, nature, objects of research, specific aims, research questions and suggestions for improving mathematics teacher education" (Tirosh, 2007, p. 143). Again, research method was apparently not a category to name. (Gellert, Becerra &amp; Chapman, 2013, p.328).</font></p>  		    <p align="justify"><font face="verdana" size="2">Development of Participatory Action Research in Latin America</font></p>  		    <p align="justify"><font face="verdana" size="2">Participatory action research has been developed in Latin America as a critical and transformative conception. The terminology was introduced by Marja&#45;Lissa Swantz in 1970 and achieved recognition at the World Symposium on Action Research and Scientific Analysis in Cartagena, Colombia, in 1977. This event examined the issue of participation, noting that a central point had to do with the need to break the classic pairing of research subject and object. It is assumed that those setting the research problem, those who analyze and solve problems, are actors who are involved, called base groups, which are grouped for the "action" of researching any fact or issue that affects them, looking for its transformation.</font></p>  		    <p align="justify"><font face="verdana" size="2">Among the notable educators&#45;researchers and advocates of this new focus was Orlando Fals Borda, who put forward a radical perception about research coupled with political commitment in his Militant Sociology (1986, 1995, 2003), a work in which he presented science as being committed to the so&#45;called popular sectors.</font></p>  		    <p align="justify"><font face="verdana" size="2">Similarly, the influential work and writings of Paulo Freire ... , Luis Bigott ... and by Ezequiel Ander&#45;Egg ... were important in conceptualizing participatory action research to the point where it offered a strong theoretical base. Fals Borda ., who emphasized the necessity of social transformations, defined participatory action research as a social praxis that enabled problems of exploitation, dependence and issues associated with retention of power among the privileged few to be identified and challenged.</font></p>  		    <p align="justify"><font face="verdana" size="2">However, research in mathematics education in Latin America has long been dominated by a positivist paradigm and a psychological orientation (Messina, 1999). G&oacute;mez and Valero (2004), reflecting on ICME10 and the 28th Conference of the International Group for the Psychology of Mathematic Education (PME 28) held in 2004, spoke of a shift in attention from the learning of mathematics to its teaching, and added that this shift was manifest in research in mathematics education in Latin America. According to G&oacute;mez and Valero, the knowledge and the beliefs of mathematics teachers, including their initial and in service training, had become important foci for research. In their analysis of the research presented at ICME 10 and PME 28, G&oacute;mez and Valero (2004) noted increased interest in studying the social aspects that affect mathematics and its teaching and learning: "Topics of democracy, equality, diversity or gender appear more and more frequently in the research literature" (p. 3).</font></p>  		    <p align="justify"><font face="verdana" size="2">According to G&oacute;mez and Valero (2004), in modern mathematics education research "most studies use qualitative methods and tend to worry about the detailed description and interpretation of specific phenomena" (p. 3). In short, it seems as if research in mathematics education has evolved as much in its sphere of interest as in its methodologies. Different international forums have revealed the need to pay attention to the diverse social aspects that strongly influence the teaching of mathematics and the impact that these aspects have on the possibility of giving access for a growing number of students to socially valued forms of mathematical knowledge.</font></p>  		    <p align="justify"><font face="verdana" size="2">Action research in mathematics education in Latin America has been steadily gaining ground and importance. That has been documented by the annual meetings of the Colombian Association of Mathematics Education (ASOCOLME), at which numerous papers have been presented for which action research has been a fundamental methodological guide. In the Research and Advanced Studies Center of the National Polytechnic Institute of Mexico (CINVESTAV) a combination of four methods has predominantly been used: action research, didactic engineering, developmental psychology, and socio&#45;epistemology (Cantoral, 2000). The 12<sup>th</sup> Interamerican Conference of Mathematics Education (IACME XII) held in 2007 in Mexico, the 6th Ibero&#45;American Conference on Mathematics Education (CIBEM VI) held in Chile in 2009, and the Latin American Meeting of Mathematics Education (RELME), have all shown how action research can be used as a methodology that opens new sources of inquiry for mathematics education, in which historical, social, cultural and political issues are brought together to enable the process of teaching and learning of mathematics to be seen as a significant undertaking of humans (Rojas Olaya, 2011). (Gellert, Becerra &amp; Chapman, 2013, pp. 347&#45;348)</font></p> 	</blockquote>  	    ]]></body>
