id="gsc_oci_descr"><div class="gsh_small">Las tecnologías de la información y la comunicación (TIC) están cambiando las formas de trabajar, estudiar, comunicarse, acceder a la información y ocupar el tiempo libre. Esto ha supuesto que la competencia digital adquiera una relevancia cada vez mayor en la educación, postulándose como una competencia clave para el desarrollo personal y laboral del alumnado en la sociedad actual. A pesar de ello, las pruebas PISA 2012 han revelado unos resultados claramente mejorables en la competencia digital del alumnado español, que obtuvo unas puntuaciones mucho menores que la media de la OCDE en las pruebas digitales de matemáticas y lectura. Por lo tanto, uno de los retos de la educación en España sigue siendo el desarrollo de una competencia digital acorde con el contexto socio-tecnológico actual. Este proyecto de innovación educativa (PIE) pretende contribuir a mejorar la competencia digital en el alumnado de la ESO, mediante el desarrollo y aplicación de actividades didácticas adaptadas a las necesidades de la nueva generación de estudiantes. En primer lugar, se ha definido un marco conceptual de la competencia digital, que ha constituido la base para posteriormente preparar las actividades didácticas y los instrumentos de evaluación correspondientes. Este marco conceptual entiende la competencia digital como una competencia múltiple que abarca cuatro dimensiones formativas: (1) Dimensión tecnológica, relativa al dominio técnico de los recursos tecnológicos; (2) Dimensión cognitiva, centrada en el uso inteligente de la información y la comunicación; (3) Dimensión actitudinal, basada en la adquisición de …</div></div></div><div class="gs_scl"><div class="gsc_oci_field">Các bài viết Scholar</div><div class="gsc_oci_value"><div class="gsc_oci_merged_snippet"><div><a href="/scholar?oi=bibs&cluster=4530439143974460052&btnI=1&hl=vi">Proyecto de Innovación Educativa: Una contribución didáctica para el desarrollo de la competencia digital en el alumnado de la ESO</a></div><div>E Moliner Santisteve - 2017</div><div><a class="gsc_oms_link" href="https://scholar.google.com.tw/scholar?oi=bibs&hl=vi&q=related:lFof7WVa3z4J:scholar.google.com/">Bài viết có liên quan</a> <a class="gsc_oms_link" href="https://scholar.google.com.tw/scholar?oi=bibs&hl=vi&cluster=4530439143974460052">Tất cả 2 phiên bản</a> </div></div></div></div></div></div></div></div><div id="gs_ftr_sp" role="presentation"></div><div id="gs_ftr" class="gs_md_rmb" role="contentinfo"><div id="gs_ftr_rt"><a href="//www.google.com.tw/intl/vi/policies/privacy/">Quyền riêng tư</a><a href="//www.google.com.tw/intl/vi/policies/terms/">Điều khoản</a><a href="javascript:void(0)" ontouchstart="gs_evt_dsp(event)" role="button" aria-controls="gs_ftr_mnu" aria-haspopup="true" class="gs_press gs_md_tb">Trợ giúp</a></div><div id="gs_ftr_mnu" class="gs_md_d gs_md_ds gs_ttzi gs_md_ulr" role="menu" tabindex="-1"><a role="menuitem" href="/intl/vi/scholar/about.html" tabindex="-1" class="gs_md_li">Giới thiệu về Scholar</a><a role="menuitem" href="//support.google.com/websearch?p=scholar_dsa&hl=vi" tabindex="-1" class="gs_md_li">Trợ giúp về Tìm kiếm</a></div></div></div></body></html>
