Prácticas innovadoras de un profesor de enseñanza superior: un camino de aprendizaje en la co-creación
Authors: Rodrigues Florbela Lages Antunes
Published: April 2023

Uno de los principales retos de la educación superior es su capacidad de adaptación a la globalización compleja de la sociedad y en la cual los aprendizajes intencionales y dirigidos sean promotores de desarrollo humano, social, económico y ambiental sustentable. O sea, la creciente competencia global necesita que estas instituciones (re)piensen sus pilares de aprendizaje, concretamente qué papel debe asumir el profesor en este proceso. De hecho, en este mundo en cambios radicales emerge la necesidad de prácticas pedagógicas adecuadas a las demandas de la sociedad, asumiendo la formación continua de profesores un papel crucial. Se perspectiva como necesaria la innovación pedagógica en la cual el profesor es mediador y aprendiz-investigador del proceso de enseñanza-aprendizaje que desarrolla. Fue en este contexto que este estudio, basado en la metodología investigación-acción, se encaja. Así, se analiza, a través de la observación participante, el camino de capacitación para la co-creación de innovación de un profesor de educación superior. Se concluye de la necesidad de (re)construcción constante de la praxis educativa que es indisociable del aprendizaje continuo. ----------------------------------------------------------------------One of the main challenges of higher education it is the ability to adapt to the complex globalization of society and in which intentional and directed learning promotes sustainable human, social, economic and environmental development. In other words, the growing global competition requires these institutions to (re)think their learning pillars, specifically what role the teacher should assume in this process. In fact, in this world undergoing radical changes, the need for pedagogical practices appropriate to the demands of society emerges, assuming the continuous training of teachers a crucial role. Pedagogical innovation is seen as necessary in which the teacher is mediator and learner-researcher of the teaching-learning process that he/she develops. It was in this context that this study, based on the research-action methodology, fits. Thus, through participant observation, the training path for the co-creation of innovation of a higher education teacher is analyzed. It is concluded from the need for constant (re)construction of educational praxis that is inseparable from continuous learning.

Estos últimos años y principalmente tras el periodo pandémico, la extendida utilización de las herramientas digitales ha motivado un incremento de su uso para el desarrollo de actividades docentes. Estas herramientas tienen un especial interés con técnicas como los COIL o Collaborative Online International Learning que, aún con innumerables beneficios, también presentan ciertas limitaciones que de acuerdo con el proyecto que se quiera desarrollar, pueden ser determinantes perdiendo parte de su potencial.En este sentido, tres universidades europeas de diferentes países promovieron bajo el amparo de un programa Erasmus+, volver tras el periodo pandémico a realizar actividades presenciales con alumnos alineado con el formato COIL. Este proyecto tiene por objetico promover la activación de los espacios públicos en los centros de las ciudades, por lo que se hace necesario la presencialidad de los participantes, más allá del análisis a través de documentación o fotografías que podamos obtener o compartir digitalmente.La comunicación propuesta trata de exponer el proyecto realizado por tres escuelas de arquitectura, desarrollado bajo una metodología que ha tratado de entrelazar la actividad presencial y online, aprovechan las ventajas de cada una de ellas-----------------------------------------------------------------In recent years and mainly after the pandemic period, the use of digital tools has led to an increase in their use for the development of teaching activities. These tools are of particular interest with techniques such as COIL or Collaborative Online International Learning which, although they have innumerable benefits, also have certain limitations which, depending on the project to be developed, can be decisive in losing part of their potential. In this sense, three European universities from different countries promoted, under the umbrella of an Erasmus+ programme, to return after the pandemic period to carry out face-to-face activities with students aligned with the COIL format. The aim of this project is to promote the activation of public spaces in city centres, which makes it necessary for the participants to be present, beyond the analysis through documentation or photographs that we can obtain or share digitally. The proposed communication tries to expose the project carried out by three schools of architecture, developed under a methodology that has tried to intertwine face-to-face and online activity, taking advantage of the benefits of each one of them

Published: April 2023

Com base na revisão da literatura afeta aos conceitos primordiais circunscritos aos valores e atitudes em contexto educacional, a par da experiência / vivência pedagógico-didática dos autores, trazemos à discussão, por um lado, o estado da arte e, por outro, um olhar em perspetiva sobre o futuro da sua promoção, desenvolvimento e aprimoramento na comunidade escolar. Estas noções e conceitos (atitude e valores) foram desenvolvidos e cientificamente mensurados por um conjunto de psicólogos que trabalhou o domínio comportamental, nos anos da década de 20 do século passado, no domínio e área da Psicologia. Mais especificamente, a Psicologia Social, destacou-se pelos contributos que trouxe para a aprofundamento destes conceitos, os quais, ancoram, nestes moldes, no universo educacional, acabando por se assumirem como elementos primordiais no que concerne à compreensão dos diferentes problemas que comummente afrontam e desafiam o universo educacional, nomeadamente na área afeta à inovação pedagógica. Neste trabalho pretendemos proceder a uma reflexão crítica sobre a importância das áreas supracitadas para a temática especifica em análise-------------------------------------------------------------------------------On the basis of the literature review related to the primordial concepts surrounding values and attitudes in the educational context, together with the pedagogical and didactic experience of the authors, we bring to the discussion, on the one hand, the state of the art and, on the other hand, a prospective look at the future of its promotion, development and enhancement in the school community. These notions and concepts (attitude and values) were developed and scientifically measured by a group of psychologists who worked in the behavioural domain in the 1920s in the field and area of Psychology. More specifically, Social Psychology, stood out for the contributions it brought to the deepening of these concepts, which, anchored, in these ways, in the educational universe, ended up being assumed as primordial elements in what concerns the comprehension of the different problems that commonly face and challenge the educational universe, namely in the area related to pedagogical innovation. In this work we intend to proceed to a critical reflection on the importance of the above-mentioned areas for the specific thematic under analysis.

Authors: García Picón Jerson Stiven , Contreras Pacheco Orlando Enrique , Cortés Aguilar Alexandra
Published: April 2023

En los últimos años se ha acelerado el proceso de adopción del trabajo virtual como una nueva modalidad de trabajo innovadora. Por lo anterior, es pertinente el desarrollo de estrategias efectivas que tengan en cuenta los elementos que emergen el control y el desempeño de los teletrabajadores. En tal sentido, el comportamiento organizacional se ve afectado por la sensación de desconexión y los cambios generados en el entorno de los individuos. En consecuencia, surge interés por identificar los factores que se correlacionan e inciden con la percepción de supervisión, el desempeño, la satisfacción laboral y el deseo de continuar teletrabajando. Además, el hecho de caracterizar dichas relaciones se antoja relevante para superar los desafíos y expectativas de las empresas,entidades y organizaciones que optan por el teletrabajo como una modalidad permanente. En ese orden de ideas, en este estudio se examinan aspectos como la sensación de aislamiento, la comunicación, la cohesión entre equipos de trabajo, el compromiso, la autonomía y la relación vida-trabajo. Partiendo de lo expuesto, se propone un modelo conceptual. Finalmente, el estudio permite proyectar nociones sobre los fenómenos en cuestión, así como la identificación de nuevas oportunidades de investigación en un contexto laboral que llegó para quedarse.--------------------------------------------------------------------------------In recent years, the process of adopting virtual work as a new and innovative way of working has accelerated. Therefore, it is relevant to develop effective strategies that take into account the elements that affect the control and performance of teleworkers. In this sense, organisational behaviour is affected by the feeling of disconnection and the changes generated in the environment of individuals. Consequently, interest arises in identifying the factors that correlate with and affect the perception of supervision, performance, job satisfaction and the desire to continue teleworking. In addition, characterising these relationships is relevant to overcoming the challenges and expectations of companies, entities and organisations that opt for telework as a permanent modality. In this context, this study examines aspects such as feelings of isolation, communication, team cohesion, commitment, autonomy and the work-life relationship. On this basis, a conceptual model is proposed. Finally, the study allows the projection of notions about the phenomena in question, as well as the identification of new research opportunities in a work context that is here to stay.

The calculation of the electricity bill components is not an easy task in Spain. Such calculation is even more complex when there is a renewable system in the equation consumer-producer (Prosumer). One of the skills that the student of the course on Generation, transmission, and distribution of electricity, belonging to the master's in industrial engineering at the Polytechnic University of Valencia in Spain, must learn is how to calculate an electricity bill. This paper aims to give the students a tool to learn how to estimate a prosumer electricity bill, employing a methodology that facilitates and makes learning faster. A real prosumer Electricity bill was employed, analyzed, and calculated. Each concept will be segregated and calculated, explaining how it was obtained. The tools used for carrying out the practice are MS excel and the web of i-DE for downloading the hourly data of the invoice. A detailed method to calculate the electricity bill was obtained as a final result.

La desigualdad de género es un problema que persiste en todo el mundo provocado por diversas razones. En este artículo se muestra la investigación realizada con la Metodología de sistemas suaves donde se aplicó un instrumento de recolección de información en empresas hidalguenses, una del giro metalmecánico y una constructora, cuyo objetivo fue reconocer la situación actual de las organizaciones participantes para desarrollar alternativas que Contribuyan a la reducción de la desigualdad de género. Se obtuvo un instrumento y posteriormente, se compararon los resultados obtenidos mediante un análisis factorial de las variables relevantes: identidad y salud integral, dentro de esta última dimensión, se incluye la conciliación entre la vida personal, familiar y laboral, así como ambientes sanos y equitativos.En los resultados sobresale la existencia de estereotipos de género, también se refleja un clima organizacional armónico y sano, por otra parte, al menos la mitad de los encuestados reportan ser jefes de familia, de estos solo una tercera parte son mujeres. Finalmente, es posible afirmar que en las organizaciones hidalguenses aún se encuentra naturalizada la violencia de género en sus diferentes tipos y modalidades y se reconoce la carencia de un marco normativo dentro de las empresas para fomentar la equidad de género.----------------------------------------------------------------------Gender inequality is a problem that persists throughout the world for various reasons. This article shows the research carried out with the Soft Systems Methodology where an instrument was applied to collect information in companies in Hidalgo, a metal mechanic and a construction company, whose objective was to recognize the current situation of the participating organizations in order to develop alternatives that contribute to the reduction of gender inequality. An instrument was used and subsequently, the results obtained were compared by means of a factor analysis of the relevant variables: identity and integral health, within this last dimension, the conciliation between personal, family and work life is included, as well as healthy and equitable environments. The results highlight the existence of gender stereotypes, and also reflect a harmonious and healthy organizational climate; on the other hand, at least half of the respondents report being heads of family, of which only one third are women. Finally, it is possible to affirm that in Hidalgo organizations gender violence in its different types and modalities is still naturalized and the lack of a regulatory framework within companies to promote gender equity is recognized.

El desarrollo tecnológico en las organizaciones avanza a pasos agigantados. Esta situación, ha sido impulsada por fenómenos como la pandemia por COVID-19, acelerando aún más la necesidad de implementación de nuevas tecnologías para el aumento de la productividad empresarial. Desafortunadamente, no todas las organizaciones cuentan con los recursos suficientes para lograr una adecuada implementación tecnológica, haciendo que las mismas se rezaguen respecto al mercado,  afectando su competitividad, como lo es el caso de las Pequeñas y Medianas Empresas PYMES. Por ello, la presente investigación tiene por objetivo Establecer cuáles son los principales desarrollos tecnológicos, desde el enfoque de la tecnología 4.0, que cuentan con potencial de apoyo al mejoramiento de procesos productivos en PYMES, con el fin de brindar alternativas para el mejoramiento de los mismos a partir de su implementación. Para alcanzar este objetivo, se realizó una revisión bibliométrica a partir de software especializado, seguido de una revisión de literatura y análisis web, con el fin de determinar las necesidades, en términos tecnológicos, que poseen las PYMES, tomando como referencia las ubicadas en el Área Metropolitana de Bucaramanga, Colombia. Finalmente, se destaca como principal resultado la vigilancia y mapeo de tecnologías, además de importantes recomendaciones para futuros desarrollos en el área.----------------------------------------------------------------------------Technological development in organisations is advancing by leaps and bounds. This situation has been driven by phenomena such as the COVID-19 pandemic, further accelerating the need to implement new technologies to increase business productivity. Unfortunately, not all organisations have sufficient resources to achieve an adequate technological implementation, causing them to lag behind the market, affecting their competitiveness, as is the case of Small and Medium Enterprises (SMEs). Therefore, the aim of this research is to establish which are the main technological developments, from the 4.0 technology approach, that have the potential to support the improvement of production processes in SMEs, in order to provide alternatives for their improvement through their implementation. To achieve this objective, a bibliometric review was carried out using specialised software, followed by a literature review and web analysis, in order to determine the needs, in technological terms, that SMEs have, taking as a reference those located in the Metropolitan Area of Bucaramanga, Colombia. Finally, the main result is the monitoring and mapping of technologies, as well as important recommendations for future developments in the area.
Ayer y hoy de la energía fotovoltaica en España
Authors: Esteban Amaro Rosa , Lengua Lengua Ismael , Estellés Miguel Sofia
Published: April 2023

El contexto actual de incremento de precios del gas y, por ende, de la electricidad, en Europa, es insostenible. El precio de la energía registró en marzo un crecimiento anual en la eurozona del 44,7%, lo que ha derivado en una inflación que se sitúa en cotas máximas y que supera el 5% en los tres meses de 2022.Efectivamente, la guerra en Ucrania ha venido a agravar una situación energética en Europa, ya de por sí delicada, debido a una enorme dependencia de gas extracomunitario, principalmente ruso. Los precios de la energía no reflejan la realidad, pero sí confirman la necesidad de tomar acciones inmediatas para disminuir la dependencia energética, lo que pasa por, entre otras medidas, potenciar el autoconsumo. España dispone, en esta situación, de un recurso; la energía solar, gratuita, renovable, limpia e inagotable, del cual debe hacer uso. No sólo porque permite reducir la contaminación, mitigando el cambio climático, sino porque se presenta como una alternativa rápida y alcanzable para miles de usuarios y empresas en España que llevan meses, teniendo que pagar un precio desorbitado por la electricidad. Este trabajo presenta el estado del arte de la energía fotovoltaica en España; cuál ha sido su evolución a lo largo de los últimos 25 años, la situación tecnológica de la industria en la actualidad, el marco legal que la sustenta y la proyección que puede tener en el corto y medio plazo. ----------------------------------------------------------------The current context of rising gas and, therefore, electricity prices in Europe is unsustainable. In March, energy prices in the Eurozone recorded an annual increase of 44.7%, which has led to inflation reaching record highs and exceeding 5% in the three months of 2022. Indeed, the war in Ukraine has aggravated an already delicated energy situation in Europe due to an enormous dependence on non-EU gas, mainly Russian. Energy prices do not reflect reality, but they do confirm the need to take immediate action to reduce energy dependence, which involves, among other measures, boosting self-consumption. In this situation, Spain has a free, renewable, clean and inexhaustible resource, solar energy, which it should make use of. Not only because it can reduce pollution, mitigating climate change, but also because it is a quick and achievable alternative for thousands of users and companies in Spain that have been paying exorbitant prices for electricity for months. This paper presents the current situation of photovoltaic energy in Spain; what has been its evolution over the last 25 years, the technological situation of the industry at present, the legal framework that supports it and the projection that it may have in the short and medium term.

A questionnaire was distributed to (200) lecturers who constituted the sample of the study at the faculties of the University of Fallujah in Iraq. Based on the hypotheses, the study revealed that there isn’t a statistically significant positive effect of teacher’s personality on their readiness to implement e-learning. As well, the study indicated that there isn’t a statistically significant positive effect of institutional determinants on teacher’s readiness to execute e-learning. Finally, the study concluded that there isn’t a statistically significant positive effect of situational determinants on instructor’s readiness to apply e-learning.
Investigación, desarrollo e innovación en materia de energías renovables: la urgencia de Europa por ser energéticamente independiente
Authors: Moreno-Mas Maria , Estelles-Miguel Sofía , De la Poza Elena
Published: April 2023

El repunte del consumo de energía que se ha producido tras la fase aguda de la pandemia COVID-19 ha supuesto, a lo largo de 2021, un incremento en los precios de la energía que, tras la invasión rusa de Ucrania, han alcanzado importantes picos no previstos por los analistas. La incertidumbre en torno a la seguridad del suministro de gas natural que necesita Europa para acometer la transición energética, ha conducido a un replanteamiento de la estrategia de descarbonización que los representantes europeos se plantearon durante la COP21 de París. En este artículo analizamos el comportamiento y tendencias del mercado del gas natural, con especial enfoque en la situación en Europa, y analizaremos las consecuencias que está teniendo la actual crisis energética y económica generada por el previsible incumplimiento ruso de los acuerdos de suministro de gas natural a Europa tras la condena europea de la invasión rusa de Ucrania.--------------------------------------------------------The spike in energy consumption following the acute phase of the COVID-19 pandemic has led, throughout 2021, to an increase in energy prices which, following the Russian invasion of Ukraine, have reached significant peaks not foreseen by analysts. The uncertainty surrounding the security of natural gas supply that Europe needs to undertake the energy transition has led to a reassessment of the decarbonisation strategy that European representatives proposed during the COP21 in Paris. In this article we analyse the behaviour and trends in the natural gas market, with a special focus on the situation in Europe, and we will analyse the consequences that the current energy and economic crisis generated by the predictable Russian non-compliance with the agreements to supply natural gas to Europe after the European condemnation of the Russian invasion of Ukraine.
The origin, rationale, and impacts of regulations on robots and AI in tourism and hospitality
Authors: Webster Craig , Cain Lisa
Published: April 2023

In recent years the robot and its AI software has become increasingly a part of the hospitality and tourism economy. The automation of service industry has been a natural evolution as a result of demographic decline in many countries and the inadequacies of the alternatives to increasing automation. In this paper, the authors explore the role of regulation of service automation and the impact of such regulation on the hospitality and tourism industries. Using Porter’s Diamond Theory of National Advantage, a framework for illustrating the competitiveness of countries and their industries, the authors illustrate the role of regulation in influencing of the competitiveness of the hospitality and tourism industries. The authors demonstrate that regulatory agencies have a major impact on factor conditions, related and supporting industries, aspects of firms and the industry (firm strategy, structure and rivalry), and demand conditions. In addition, the authors discuss the intentions and the sources of regulatory policies on industry. The authors consider the various levels at which such regulations may be made and how these levels impact  global competitiveness. The authors describe the various impacts that a consensus (global regime), the European Union, and national and subnational authorities would have upon the competitive environments of the industry. Additionally, the authors discuss the importance of the political philosophy influencing the regulations, comparing how a liberal, social-democratic, and mercantilist mindset would impact the industry differently, thus impacting competitiveness massively.

Authors: Garrigos-Simón Fernando Jose , Buzova Daniela , Sanz-Blas Silvia , Narangajavana Kaosiri Yeamduan
Published: April 2023

La última década ha traído retos para el sector turístico, relacionados tanto con las nuevas necesidades y expectativas de los turistas originados a raíz de la Covid19, como con la creciente concienciación y preocupación por la sostenibilidad del turismo. El objetivo del presente trabajo se centra en poner de manifiesto la contribución que pueden y deben tener los guías turísticos no sólo en proveer una experiencia turística de calidad a los visitantes de los destinos, sino también cómo su labor puede afectar positivamente la consecución de la sostenibilidad a nivel socio-cultural. El trabajo analiza la evolución que ha experimentado el papel del guía turístico en el último siglo a través de una revisión de la literatura. Los resultados evidencian cómo la función tradicional informativa del guía turístico debe completarse hoy en día con una faceta más emocional del papel del guía, que, con su actuación, debe involucrar a los turistas de manera que cocreen juntos la experiencia del tour. Además, la formación de los guías turísticos en la nueva era post-covid debe contemplar contenidos de sostenibilidad, para impactar tanto las actividades responsables del turista en el destino, como sus actitudes y comportamientos sostenibles post-visita.------------------------------------------------------------------The last decade has brought challenges for the tourism sector, related both to the new needs and expectations of tourists brought about by Covid19, and to the growing awareness and concern for the sustainability of tourism. The aim of this paper is to highlight the contribution that tour guides can and should make not only in providing a quality tourism experience to visitors to destinations, but also how their work can positively affect the achievement of sustainability at a socio-cultural level. The paper analyses the evolution of the role of the tour guide over the last century through a review of the literature. The results show how the traditional informative function of the tour guide must nowadays be complemented by a more emotional facet of the role of the guide, who, through his or her actions, must involve tourists in such a way that they co-create the tour experience together. Furthermore, the training of tour guides in the new post-covid era must include sustainability content, in order to impact both the tourist's responsible activities at the destination and their sustainable attitudes and behaviour post-visit.

Published: April 2023

With the rapid development of modern civilization, the development of marine resources has become imminent, but seawater corrosion has become one of the most important factors hindering development. In order to overcome this problem, an environmentally friendly physical anticorrosion scheme based on a magnetic field () has been proposed. In this context, we investigate the effect of the Lorentz force and gradient force of a magnetic field on the corrosion behavior of carbon steel in seawater. The experimental results show that the gradient force of a magnetic field inhibits corrosion while the Lorentz force promotes corrosion. Especially in the (corrosion electrical field) case, the Lorentz force influence on the corrosion behavior is greater than the gradient force, while in case gradient force dominates. In addition, the effect mechanism of magnetic field on the corrosion behavior of carbon steel in seawater was revealed by comparison of corrosion product composition in different reaction regions and electrochemical impedance spectrum analysis, which will provide an experimental basis for the application of environmentally friendly marine anticorrosion technology based on a magnetic field.

El nuevo horizonte constitucional para la Unión Europea: a propósito de la entrada en vigor del Tratado de Lisboa y la Carta de Derechos Fundamentales
Authors: Sarrión Esteve Joaquín
Published: April 2023

Con la entrada en vigor del Tratado de Lisboa, la Carta de Derechos Fundamentales adquiere eficacia jurídica, y se prevé la posibilidad de que la Unión Europea se adhiera al Convenio de Roma. En este trabajo pretendemos acercarnos a los antecedentes que han justificado una huída de la tutela de los derechos fundamentales de base jurisprudencial desarrollada por el Tribunal de Justicia hacia una formalización de la misma, a través de dos caminos: la formalización a través de una declaración de derechos que se ha concretado en la Carta de Derechos Fundamentales, y la adhesión al Convenio de Roma.Finalmente trataremos de esbozar las perspectivas que se abren en el horizonte constitucional de la Unión Europea, donde gozamos ya de un Tribunal de Justicia que ejercerá una función tan constitucional como la tutela de los derechos fundamentales, contenidos ya en una declaración con fuerza jurídica, cuya interpretación se vincula al Convenio de Roma.

El objetivo de nuestro trabajo es analizar la información textual publicada en el informe de gestión y el informe de resultados de las empresas cotizadas en el Ibex 35 para el periodo 2018-2021. En particular, estudiamos el tono de la información publicada y la extensión de dichos documentos. Nuestros resultados ponen de manifiesto que las empresas del Ibex 35 no incorporan sesgos significativos en la información narrativa de informes de gestión e informes de resultados, que está marcada por un reducido nivel de optimismo y un alto nivel de realismo. Asimismo, tampoco se observan diferencias importantes en el tono de la información narrativa determinadas por el rendimiento económico de las empresas o por el año en el que se publican los documentos. Sin embargo, la extensión del informe de resultados y, especialmente de los informes de gestión, ha crecido significativamente en el periodo analizado, particularmente en las empresas con menor rendimiento.

The era of globalization and digitalization requires teachers to be able to innovate in managing learning. Proper management determines the success of learning. The success of learning is a series of stages of activities consisting of planning, implementation, and evaluation of learning. The quality of the learning planning stages will be better when they are compiled, implemented, and evaluated jointly by the learning team. Collaborative activities encourage participatory processes among members. Collaboration will develop and improve the learning process. Improving the quality of learning is a demand and obligation that must be done by the teacher. One way to improve the quality of learning is with lesson study activities. Critical thinking skills are very important because they can be used to solve problems and as considerations in making reasonable decisions about what to believe and what to do. A teacher needs to create a mathematics learning process that requires students to be able to develop their critical thinking skills. This study aims to analyze students' critical thinking skills in learning fractions using the inquiry method through lesson study activities for fourth grade students at SD Mapans (Muhammadiyah 08 Semarang) for the 2021/2022 academic year. The research method used is a qualitative approach with descriptive analysis methods. Recommendations that can be conveyed from this lesson study activity are (1) the ability of teachers to manage learning is very influential on the enthusiasm and response of students in participating in learning; (2) The varied learning media are able to attract students' interest and focus to participate in the learning process until the end of the activity; and (3) the right approach and method can improve the quality of learning. The conclusions from the implementation of this lesson study are (1) Learning through lesson study fosters critical thinking skills for both teachers and students; (2) Collaboration of various parties in preparing lesson plans through lesson study improves the ability of teachers to manage learning activities; and (3) the ability to think critically in students can be grown through an inquiry method approach which is collaborated in lesson study activities.

The Human Development Index (IPM) is a tool to measure development performance, especially human development carried out in a certain area at a certain time or specifically. This study examines HDI and the components of HDI, the data used is data on the values of HDI components for 35 districts/cities in Central Java Province. The variables used in this study were HDI (Y) as the dependent variable, AHH (X1), AMH (X2) and PPP (X3) as independent variables. The research examines the effect of spatial dependencies by using the area approach. Next is given the SEM application to identify how much influence the HDI constituent components can have on the HDI level in Central Java. The results of the study show that the distribution of HDI in Central Java Province has a regional grouping pattern. The results of modeling using SEM show lambda and all significant variables. The SEM model produces an AIC of 43.8540 which is better than the regression OLS method with an AIC of 45.6231.
