RESUMEN El proceso de la lectura crítica en las universidades ecuatorianas está enfocado en un nuevo paradigma epistémico y tiene entre sus retos y desafíos la preparación de los estudiantes. El ...objetivo general de la investigación es diagnosticar la incidencia de la lectura crítica en el aprendizaje de los estudiantes de la carrera de Ingeniería Industrial en su primer módulo y de qué manera se puede aportar al fortalecimiento del aprendizaje de los estudiantes. Se realizó una investigación de tipo descriptiva, que permitió conocer las situaciones, hábitos de lectura predominantes en los estudiantes del módulo en estudio. Se emplearon métodos como el analítico-sintético, inductivo-deductivo e histórico-lógico, para obtener la evidencia de la dimensión social de los estudiantes del Módulo I de la carrera Ingeniería Industrial. Ello permitió obtener como resultado, las dificultades que los estudiantes presentan en su desempeño académico. Además, se reconoce que es necesario por parte de los docentes la orientación, el asistir a los estudiantes en la apropiación de la lectura crítica para mejorar su nivel de comprensión, análisis, síntesis y con ellos mejorar su aprendizaje.
Cilj istraživanja je utvrditi mišljenje studenata primarnog obrazovanja o
obilježjima profesije. Nezavisne varijable istraživanja su trenutačna godina studija, vrsta prethodno završene srednje škole ...te modul/smjer koji studenti pohađaju. Istraživanje je provedeno anketnim upitnikom u akademskoj godini 2019./2020., a uzorak čine studenti/ce prve i pete godine Učiteljskog fakulteta Sveučilišta u Zagrebu. Rezultati pokazuju da studenti primarnog obrazovanja prepoznaju obilježja profesije te postojanje statistički značajne razlike s obzirom na godinu studija i vrstu prethodno završene srednje škole.
In this paper, the opinion of students of primary education regarding the characteristics of a profession will be determined. The aim of this research is to establish opinion of students of primary education regarding characteristics of a profession. Independent variables are current year of study, previously finished high school and module/course
students take. The research was conducted with a questionnaire in the academic year 2019/2020. The sample consisted of students of the first and fifth year at the Faculty of Teacher Education, University of Zagreb. The results show that students of primary education recognize characteristics of a profession. There is a statistically significant difference between students of different years of study and with different previous education.
Particles of flooded gum (Eucalyptus grandis) were bonded using three bio-based adhesives - anhydrous citric acid (CA), tannin-citric acid (TCA) and ricinoleic acid (RA) - from renewable sources and ...hot pressed to produce medium density particleboard (MDP). The bonding capacity of such adhesives and properties of the MDP were evaluated and compared to the requirements of seven grades of particleboards, according to the EN 312 (2010) standard. The RA did not create adhesion reaction with the wood particles. Adhesives formulated with CA and TCA presented capacity to bond eucalyptus particles into MDP confirmed by esterification reactions of the FTIRS analysis. MDP bonded with CA met requirements as high as grade P5 of the EN 312 (2010) standard for static modulus of elasticity (MOE) and internal bond (IB) and P2 for modulus of rupture (MOR). Panels bonded with TCA met requirements up to grade P3 for MOE, however, did not withstand water absorption.
Za izradu iverice srednje gustoće (MDP) upotrijebljeno je iverje drva eukalipta (Eucalyptus grandis) lijepljeno trima ekološki prihvatljivim ljepilima dobivenim iz obnovljivih izvora na bazi anhidrida limunske kiseline (CA), taninsko-limunske kiseline (TCA) i ricinoleinske kiseline (RA) te prešano u vrućoj preši. Kvaliteta lijepljenja tim ljepilima i svojstva iverice ocijenjeni su usporedbom sa sedam klasa uporabe prema normi EN 312 (2010). Ljepilo RA nije uspjelo povezati drvno iverje. Ljepila CA i TCA pokazala su sposobnost lijepljenja eukaliptova iverja pri izradi MDP ploče, što je potvrđeno reakcijom esterifikacije u FTIR analizi. MDP ploča izrađena primjenom CA ljepila udovoljava visokim zahtjevima klase uporabe P5 prema EN 312 (2010) za modul elastičnosti (MOE) i čvrstoću na raslojavanje (IB) te klase P2 za modul loma (MOR). Ploče izrađene uporabom TCA ljepila ispunile su zahtjeve klase uporabe P3 za modul elastičnosti (MOE), ali nisu zadovoljile zahtjeve o upijanju vode.
