From everyman's right to everyman's possibility
2016
This article describes a blended learning study module that was carried out in class teachers’ adult education. The goal of the planning of this module was to create a learning environment that would give a student an optimal learning experience in versatile, authentic, e-learning environments. In the study, the ubiquitous learning model was based on the principles of transformational pedagogy (OED). The module was carried out in flexible and versatile learning environments based on transformational pedagogy, where knowledge also included command of the 21st century teaching skills 21. The theoretical framework of the study module followed the model of contextual-pedagogical model [18]. The…
Digital media in blended coaching : interaction and distance presence in adult education
2011
In this study were studied the dimensions and advantages of the digital media in the adult education and distance presence. The point of view and limiting of the study was coaching and the significance of face-to-face interaction in it. The study was partly based on my three earlier reports about the digital media in the direction of teaching training. Main question of the three reports was would the digital media supply some new dimensions and benefits for teaching training guidance? It was seen, in the reports, as the biggest disadvantage that the distance presence is not a genuine situation because there is lack of (quick) interactivity. The need for a flexible two-way communication chan…
Jokamiehen oikeudesta jokamiehen mahdollisuudeksi
2016
Uudenlaisten pedagogisten mallien pohjalle suunnitellut opintokokonaisuudet lisäävät yliopistojen opintotarjonnan saavutettavuutta ja antavat yksilöille paremmat mahdollisuudet elinikäiseen oppimiseen. Luokanopettajien aikuiskoulutuksessa on käynnissä laaja oppimisympäristöjen kehittymistyö, jossa e-oppimisella on näkyvä sija. Aikuisopiskelijoiden elämäntilanne luo haasteita täysipäiväiselle läsnäololle ja siitä noussut tarve on nähty Luokanopettajien aikuiskoulutuksessa myös mahdollisuutena laajentaa henkilökunnan pedagogista osaamista uudistavien e-oppimiskäytänteiden ja pedagogisten mallien suunnittelijoina, kehittäjinä ja toteuttajina. Luokanopettajien aikuiskoulutuksen 25-vuotinen taiv…
Geochemistry, Sr–Nd–Pb isotopes and geochronology of amphibole- and mica-bearing lamprophyres in northwestern Iran: Implications for mantle wedge het…
2015
Highlights • Northwestern Iranian lamprophyres have alkaline and calc-alkaline nature. • Studied lamprophyres are emplaced during Late Cretaceous to Late Miocene time. • Lamprophyres originated from different metasomatised lithospheric mantle. Abstract Lamprophyres of different age showing distinctive mineralogy, geochemistry and isotopic ratios are exposed in northwestern Iran. They can be divided into Late Cretaceous sannaite, Late Oligocene-Early Miocene camptonite (amphibole-bearing) and Late Miocene minette (mica-bearing) and spessartite (amphibole-bearing) lamprophyres. Sannaites have high-Ti amphibole along with high-Ti and Al clinopyroxene, and they are characterised by homogeneous …
Antioxidant Activity and Release Kinetics of Caffeic and p-Coumaric Acids from Hydrocolloid-Based Active Films for Healthy Packaged Food
2017
International audience; Sustainable hydrocolloid-based films containing natural antioxidants, caffeic and p-coumaric acids at different concentrations of 0.5%, 1%, 5%, and 10% w/w of polymers, were designed for packing fatty foods. Antioxidant activities and kinetics for all film formulations were assessed using radical scavenging activity (DPPH), reducing power, and iron chelating ability. Release kinetics of the antioxidants from the films into a food simulant (96% ethanol) were analyzed. The intermolecular interactions between antioxidants and polymers chains were assessed by Fourier transform infrared attenuated total reflectance (FTIR-ATR) and related to the film properties. Antioxidan…
Gamifying Teacher Students’ Learning Platform
2020
This paper presents initial results from a study exploring teacher students’ experiences related to the gamification of an online learning platform in higher education. The aim was to get an understanding of the participants’ views regarding the use of game elements and to examine the user type profile of this group in order to explore the potential of applying user types in planning gamification solutions for teacher students. The participants’ overall experience of having game elements as part of their course platform was principally positive. User types students presented were investigated using the Hexad scale adapted from game design: in this user group, Socialiser and Philanthropist w…
A Blended Learning Solution and the Impacts on Attendance and Learning Outcomes
2011
Blended learning based on lecture videos and face-to-face teaching provides good opportunities for students for participation in education, regardless of time or place. The article describes a blended learning solution that is based on face-to-face teaching and the use of streaming lecture videos as it has developed in connection with master studies in mathematical information technology. The particular focus of this article is on the use of lecture videos and the impacts of blended learning on participation in education and on learning outcomes. According to the results, lecture videos have become very popular among students. Moreover the use of lecture videos increases participation activ…

Nell''articolo si evidenziano gli aspetti più significati…
Toward the Decarbonization of Plastic: Monopolymer Blend of Virgin and Recycled Bio-Based, Biodegradable Polymer.
2022
Decarbonization of plastics is based on two main pillars: bio-based polymers and recycling. Mechanical recycling of biodegradable polymers could improve the social, economic and environmental impact of the use of these materials. In this regard, the aim of this study was to investigate whether concentrations of the same recycled biopolymer could significantly affect the rheological and mechanical properties of biodegradable monopolymer blends. Monopolymer blends are blends made of the same polymers, virgin and recycled. A sample of commercially available biodegradable blend was reprocessed in a single-screw extruder until two extrusion cycles were completed. These samples were exposed to gr…
Effect of Polyhydroxyalkanoate (PHA) Concentration on Polymeric Scaffolds Based on Blends of Poly-L-Lactic Acid (PLLA) and PHA Prepared via Thermally…
2022
Hybrid porous scaffolds composed of both natural and synthetic biopolymers have demonstrated significant improvements in the tissue engineering field. This study investigates for the first time the fabrication route and characterization of poly-L-lactic acid scaffolds blended with polyhydroxyalkanoate up to 30 wt%. The hybrid scaffolds were prepared by a thermally induced phase separation method starting from ternary solutions. The microstructure of the hybrid porous structures was analyzed by scanning electron microscopy and related to the blend composition. The porosity and the wettability of the scaffolds were evaluated through gravimetric and water contact angle measurements, respective…
