Combined effect of low-molecular-weight organic acids and creosote on phosphatase activities in sandy soil
2018
This paper assesses the impact of creosote and low-molecular-weight organic acids (LMWOAs) on the activity of acid phosphomonoesterase, alkaline phosphomonoesterase, phosphotriesterase, and inorganic pyrophosphatase in soil. The experiment was carried out on loamy sand samples with organic carbon content of 8.71 g · kg -1 , with the following variable factors: dosages of creosote: 0, 0.5%, and 2.5%; type of LMWOAs: oxalic acid, tartaric acid, and citric acid in the amount of 50 mmol · kg -1 of soil; days of experiment: 1, 7, 14, 28, 56, 112. Obtained results showed that contamination with creosote caused decrease in the activity of soil phosphatases. The observed effect did not always incre…
School Staff-centered School Development by Communicative Action: Working Methods for Creating Collective Responsibility - From the Idea to Action
2020
School development is often seen as a concerted (re-)action to educational policies, curriculum development, and change in education laws or regulations, and sometimes, as stakeholders’ reactions to low school performance. Generally, school development incorporates organizational, managerial, and educational activities and measures. This is done to adapt to the new situation to achieve the desired changes and goals initiated by a given curriculum reform. In contrast, this paper focuses on school staff–driven development: It describes how teachers together with paraprofessionals contribute to school-development. Using collective responsibility creating working methods of communication, the e…
Is a seminar based on student-created screen capture videos a meaningful way of learning?
2008
We ran a problem-based seminar with screen capture videos. The students worked in small groups of two or three students or they completed the coursework individually. In this seminar the students had a workspace in the Optima environment for publishing their coursework videos. At the final phase of the course the students were expected to familiarize themselves with the presentations of other groups. In this paper we analyze the benefit of our problem-based coursework on the web by comparing the different phases of it. After each phase the students were expected to analyze the benefit of it for their learning. peerReviewed
Osallistava sävellytysmenetelmä musiikinopetukseen : peruskoulun opetussuunnitelman 2014 tavoitteita ja oppimisen ydinmetaforia toteuttamassa
2017
In my case study, I used two composing tasks to examine how the inclusive composing method (OSM) I have developed promotes the achievement of the aims of the new core curriculum for basic education 2014 and realises the core metaphors of learning. I have created a learning triangle tool to determine how the musical contents, the principles for developing working culture and the goals of music teaching, transversal competences and national education are linked with the latter. In addition to participation and the gaining and creation of knowledge, I included operative competences in these core metaphors. I examined the means OSM offers to evaluate how the students achieve the aims of musical…
Comparing male and female students’ self-efficacy and self-regulation skills in two undergraduate mathematics course contexts
2018
International audience; Students' efficacy beliefs have a positive influence on students' academic achievement and retention, especially for female students. These beliefs are closely linked to students' ability to regulate their learning. In this quantitative study, students' self-efficacy and self-regulation of learning are compared in two university mathematics courses that differ in content but also in their pedagogical setting: one is a more traditional lecture-based course, and the other course is taught with the Extreme Apprenticeship (XA) method. The analysis is based on the same cohort of students in the two contexts (N=91). The results suggest that students have higher self-effica…
"Jeg vil leve mitt liv med å være meg selv" : om selvhevdelse i psykisk helsearbeid
2012
Masteroppgave i psykisk helsearbeid ME-504 2012 – Universitetet i Agder, Grimstad Kommunene har til oppgave å tilby lokalsamfunnet et virkningsfullt psykisk helsearbeid slik at den enkelte innbygger som har behov for det skal få tilbud om best mulig hjelp til å fungere i et krevende samfunn sammen med andre. Sandnes kommune tilbyr blant annet kurs i selvhevdelse til mennesker som har store utfordringer i forhold til å hevde seg selv. Hensikten med denne studien er å finne ut om deltakere erfarer å få bedre psykisk helse etter å ha deltatt på kurs i selvhevdelse. Problemstillingen i studien er ”Hvilke erfaringer har deltakerne med selvhevdelse etter å ha gjennomgått kurs i selvhevdelse?”. Op…
Inhibition of denitrification and N2O emission by urine-derived benzoic and hippuric acid
2006
Abstract Hippuric acid (HA) in cattle urine acts as a natural inhibitor of soil N2O emissions. As HA concentration varies with diet, we determined critical HA levels. We also tested the hypothesis that the inhibition occurs because the HA breakdown product benzoic acid (BA) inhibits denitrification rates. During a 64-day incubation, we quantified emissions from artificial urine varying in HA, BA and glycine (Gly) concentrations, added to a sandy pasture soil. Increasing HA concentration from 0.4 to 5.6 mmol kg−1 soil significantly decreased the average N2O flux by 54%. At 3.9 mmol kg−1 soil, denitrification levels were 50% reduced for BA as compared to Gly. We conclude that HA inhibits both…
Learning to read for the first time as adult immigrants in Finland : Reviewing pertinent research of low-literate or non-literate learners’ literacy …
2018
Against the backdrop of increasing global humanitarian migration to highly literate countries and the resulting necessity and challenge to provide language and literacy education to non-literate or low-literate adult second language (L2) learners, this article calls for more research on a new population of late literacy learners, particularly in Finland. The article begins by outlining the pressing necessity for research on this special group of L2 learners who has traditionally been ignored by Second Language Acquisition (SLA) research. It will then go on to illuminate essential components of developing reading literacy, drawing on relevant previous research on pre-literates. Further, the …
Revista electrónica de investigación y evaluación educativa
2016
El Programa para la Evaluación Internacional de Alumnos (PISA) proporciona un marco en el que más de 80 países colaboran para construir métricas globales avanzadas para explorar los conocimientos, habilidades y atributos del estudiantado. El diseño de las evaluaciones plantea importantes desafíos conceptuales y técnicos, como el éxito del aprendizaje. Más allá de una base conceptual sólida, PISA necesita cumplir una serie de exigencias a veces contradictorios. Los/as administradores de escuelas, autoridades normativas y los docentes deben ser capaces de utilizar esta información de la evaluación para determinar cómo crear mejores oportunidades para el aprendizaje de los estudiantes. Las eva…
Algunas consideraciones en torno a la Evaluación del Sistema Educativo y a lo que ésta comporta
1994
In this article we considere the reasons for evaluating the educational system. The quality of education is a preoccupation of the governments, specially in time of crisis and of educational reforms and this quality needs and evaluation of all the educational system. In Spain the National Institute of Quality and Evaluation has been recently created in order to carry out this evaluation. We reflect about the subject and also about the methods and the agents of this evaluation. We ask for a democratic and cooperative evaluation.
