PENINGKATAN MOTIVASI DAN HASIL BELAJAR SISWA KELAS IV PADA PELAJARAN IPS TENTANG PETA LINGKUNGAN SETEMPAT DENGAN MENGGUNAKAN MODEL PROBLEM BASED LEARNING (PBL)

Penelitian Tindakan Kelas (PTK) ini dilaksanakan di SDN Tilil 2 Bandung Kecamatan Coblong Kot a Bandung dengan jumlah siswa 31 orang siswa. Penelitian ini dilatar belakangi dengan masalah kurangnya motivasi dan hasil belajar karena guru kurang melibatkan siswa dalam proses pembelajaran, sehingga motivasi belajar siswa masih rendah yang menyebabkan siswa menjadi bosan dan malas un tuk mengikuti pembelajaran. Untuk mengatasi permasalahan tersebut dilakukan upaya dengan cara menerapkan suatu model pembelejaran Problem Based Learning (PBL ). Penelitian Tindakan Kelas (PTK) ini bertujuan untuk meningkatkan motivasi belajar siswa pada mater i Peta Lingkungan Setempat. Penelitian ini dilakukan dalam 3 siklus, setiap siklusnya terdiri dari 2 kali pertemuan atau pembelajaran. Adapun tahapannya terdiri dari tahap perencanaan, pelaksanaan, obs ervasi, analisis, dan refleksi. Hasil penelitian menunj ukkan adanya peningkatan motivasi dan prestasi belajar siswa pada setiap siklusnya. Hasil penelitian prestasi belajar s iklus I nilai rata - ratanya 64,0 , s i klus II nilai rata - ratanya 83,2 , si k lus III nilai rata - ratanya 83,5 Jumlah siswa yang mencapai keberha silan meningkat setiap siklu s nya, dari siklus I sebesar 25,8% atau sebanyak 8 orang siswa, siklus II sebesar 77,4% atau sebanyak 24 orang si s wa, dan siklus III sebesar 83,9% atau sebanyak 26 orang siswa. Begitu pula dengan hasil pada motivasi belajar siswa meningkat, pada siklus I pengakuan positif sebesar 60,2 %, siklus II pengakuan positif sebesar 66,7 %, dan siklus III pengakuan positif sebesar 81 %. Sedangkan pada pengakuan neg atif siklus I seb esar 65,6%, siklus II sebesar 70%, dan siklus III sebesar 86 %. Berdasarkan hasil yang diperoleh dalam penelitian, dapat disimpulkan bahwa pembelajaran dengan menggunakan mo del pembelajaran Problem Based Learning (PBL) dapat meningkatkan motivasi dan h asil belajar kelas IV SDN Tilil 2 Bandung materi peta lingkungan sete mpat.

HUBUNGAN ANTARA RIWAYAT MIOPIA DI KELUARGA DAN LAMA AKTIVITAS JARAK DEKAT DENGAN MIOPIA PADA MAHASISWA PSPD UNTAN ANGKATAN 2010-2012

Background : Myopia is a refractive error with incidents between 50 % to 80,3 %at some hospitals in Indonesia. The prevalence of myopia among medicalstudents is nearly twice as high as in general population. Risk factor thatassociated with myopia is genetic or herediter and time spent in near-work.Objective : The aim to determine the association between parental myopia andtime spent in near-work with myopia in medical student faculty of medicinetanjungpura university grade 2010-2012. Method : This study was analytic observational cross sectional study. Thesamples in this study were 70 medical students faculty of Medicine TanjungpuraUniversity Grade 2010-2012, that suitable with inclusi and eksclusi criteria. Thedata was analyzed by Chi-square test with p<0,05.Result : Total subyek is 70 people, 44 (62,9%) with myopia and 26 (37,1%)without myopia.. Based on the analyze, p value has a significant association forparental myopia (p=0,010) with myopia. There were no statistically associationbetween reading book for study (p=0,961), reading book for pleasure (p value isconstant), writing (p=0,298), using laptop, handphone, and playing video games(p=0,940), watching tv (p=0,701) with myopia.Conclusion : There was significant association between parental myopia withmyopia in medical student faculty of medicine tanjungpura university grade 20102012.Therewerenosignificantassociationbetweentimespentinnear-workwithmyopiainmedicalstudentfacultyofmedicinetanjungpurauniversitygrade20102012Keywords:myopiatimespentinnear-workparentalmyopi

Fibrados vetoriais e módulos projetivos

Orientador: Prof. Dr. Eduardo HoefelDissertação (mestrado) - Universidade Federal do Paraná, Setor de Ciências Exatas, Programa de Pós-Graduação em Matemática. Defesa : Curitiba, 31/08/2016Inclui referências: p.76Resumo: Entre 1935 e 1940 tornou-se parte do ambiente matemático a idéia de fibrados, graças ao trabalho do matemático Hassler Whitney. Em 1962 Riehard G, Swan mostrou ao mundo que existe uma correspondência muito bem definida entre o módulo de seções de fibrados vetoriais e módulos projetivos. No presente trabalho faremos um estudo partindo de definições topológicas e algébricas básicas, passando pelas definições gerais e estruturais de fibrados vetoriais, tanto quanto as características de fibrados vetoriais em alguns espaços topológicos bem conhecidos. Por fim veremos que a correspondência entre fibrados vetoriais e módulos projetivos nos dá um a forma nova de verificar a projetividade de alguns espaços. Palavras-chave: Fibrados; Fibrados Vetoriais; Módulos; Módulos Projetivos; Módulo de Seções.Abstract: Between 1935 and 1940 it became part of the m athem atical environment the idea of bundles, thanks to the work of the m athem atician Hassler Whitney, In 1962 Richard G, Swan showed the world th a t there is a correspondence well defined between the module of sections of vector bundles and projective modules. In this work we will do a study starting from topological and algebraic basics definitions, going through the general and structural definitions of vector bundles, as well as the characteristics of vector bundles on some topological spaces well known. Finally we see th a t the correspondence between vector bundles and projective modules gives us a new way to cheek projectivity of some spaces.

A escuta de crianças vítimas de abuso sexual intrafamiliar na concepção de profissionais que atuam no âmbito do Judiciário

Resumo &nbsp; O objetivo desta pesquisa foi analisar as concepções de profissionais da área da saúde e operadores do Direito a respeito da escuta das crianças que experimentaram abuso sexual intrafamiliar. Foi realizado um estudo descritivo transversal, utilizando-se a técnica de entrevista individual semiestruturada para coleta de dados e análise de conteúdo para análise dos dados. Participaram 15 profissionais da área da saúde e operadores do Direito. Os resultados apontaram para a existência de limitações na escuta da criança no âmbito do Judiciário e para o despreparo dos profissionais para realização dessa escuta. Identifica-se uma tensão entre as necessidades da criança e as demandas do Judiciário com relação à constituição da prova e responsabilização do agressor. Conclui, salientando a importância do trabalho interdisciplinar. &nbsp; Listening to children victims of sexual abuse in the family context according to professionals of the Judiciary System &nbsp; &nbsp; Abstract &nbsp; The goal of this study was to analyze the conceptions of Health Professionals and Law Operators of the Judiciary System in what concerns listening to children who have suffered sexual abuse in the family context. A transversal descriptive study was carried out, using semi-structured individual interviews for data collection and content analysis. The participants were fifteen Health Professionals and Law&nbsp; Operators. The results indicated limitations in listening to the child in the judiciary context, as well as professionals unprepared for the task. There is a tension between the child’s needs and the judiciary’s demands in relation to the collection of evidence and the offender’s accountability. We conclude stressing the importance of interdisciplinary work. &nbsp; &nbsp; &nbsp; Resumen &nbsp; Este estudio tuvo como objetivo examinar las concepciones de escuchar a los niños que han sufrido abuso sexual intrafamiliar acuerdo con los profesionales en el área de Salud y los operadores de la ley que actúan en el seno del Poder Judicial.
