Proposta di un framework per la progettazione didattica a scuola
2021
Il presente lavoro di ricerca ha inteso verificare la validità di una struttura predefinita per la stesura di un progetto didattico, precisamente quella fornita agli studenti durante il tirocinio. La progettazione è un fattore chiave nella mediazione tra insegnamento e apprendimento a scuola; le sue fasi investono sia il piano gestionale sia quello delle finalità generali, fino a quello dell’agire in classe e della valutazione. Nel tirocinio 684 futuri insegnanti di scuola dell’infanzia e primaria, frequentanti il corso di laurea in Scienze della Formazione Primaria di Palermo negli anni 2016-2020, hanno utilizzato un frame di progettazione e valutazione didattica; esso è stato costruito te…

Photoperiodic regulation of life-history traits before and after eclosion: egg-to-adult development time, juvenile body weight and reproductive diapa…
2012
Photoperiod is the main environmental cue used by northern insects to predict the forthcoming seasonal changes and to adjust their life-history traits to fit these changes. We studied the effects of photoperiod on egg-to-adult development time, juvenile body mass and female reproductive diapause in two northern Drosophila montana populations with different patterns of voltinism. The most interesting findings were consistent between the populations: (1) when maintained before eclosion in short day conditions, representing early autumn, the flies developed faster and were lighter than when maintained in long day conditions, representing early summer, (2) photoperiodic time measurement is appa…
Environmental Aspect Concerning Phthalates Contamination: Analytical Approaches and Assessment of Biomonitoring in the Aquatic Environment
2023
This review is a survey of recent progress in studies concerning the impact of phthalic acid esters in aquatic organisms. After introducing the classification, properties, sources, fate, and toxic effects related to phthalates, an overview of the techniques of extraction and analysis of these substances is provided. As a result, the general concepts of environmental bioindicators, biomonitoring systems, and other concepts related to phthalate contamination in the aquatic environment are presented. Recent bioaccumulation data of different phthalates are summarised in a table and organised according to the type of organism, tissue, and geographical area of sampling. Bioindicator organisms tha…
Motorisen oppimisen vaikeuden tunnistaminen ja tukeminen kouluympäristössä
2018
Motorisen oppimisen vaikeudella, kuten kehityksellisellä koordinaatiohäiriöllä (DCD), tarkoitetaan huomattavaa vaikeutta oppia uusia motorisia taitoja ja soveltaa jo opittuja taitoja uusiin tilanteisiin. Tämän tutkimuksen tarkoituksena oli kehittää opettajien käyttöön havainnointityökalu, joka auttaa tunnistamaan motorisen oppimisen vaikeuden esi- ja alkuopetusikäisillä lapsilla. Lisäksi tutkimus selvitti, miten opettajat voivat kouluympäristössä tukea lapsia, joilla on haasteita motorisessa oppimisessa. Tutkimus muodostui neljästä osatutkimuksesta. Ensimmäisessä tutkittiin systemaattisen kirjallisuuskatsauksen avulla maailmalla käytössä olevien havainnointilomakkeiden psykometrisiä ominais…

Structural and electronic elucidation of a N-heterocyclic silylene vanadocene adduct
2017
The solid and solution state structure of the vanadium(II) N‐ heterocyclic silylene (NHSi) complex, [(SiIPr)V(Cp)2] (1) is reported ( SiIPr: 1,3‐bis(2,6‐diisopropylphenyl)‐1,3‐diaza‐2‐silacyclopent‐4‐ en‐2‐ylidene). The electronic structure of 1 is probed using combination of magnetic measurements, EPR spectroscopy and computational studies. The V–Si bond strength and complex forming mechanism between vanadocene and NHSi ligand is elucidated using computational methods. peerReviewed
Las creencias epistemológicas en los estudiantes universitarios con los nuevos planes de estudios
2015
Los cambios surgidos a partir del proceso de Bolonia, centrados en una nueva metodología que implica un alumno más activo, es esperable que influyan sobre las creencias epistemológicas. Para comprobar esto, comparamos dos grupos de una misma asignatura que cursaban licenciatura (441) y grado (336) y utilizamos el Cuestionario de creencias epistemológicas (EBS) de Wood y Kardash (2002: 249). Los resultados muestran que las creencias en ambos sistemas tienden a ser similares e ingenuas o simples, con puntuaciones ligeramente superiores en el grupo de licenciatura, contrario a lo esperado. Se presentan sugerencias de mejora de la metodología docente. The changes from the Bologna Process, focus…
Responses of zooplankton to cane sugar additions to a small humic lake, Alinen Mustajärvi
2010
The response to projected increase in dissolved organic carbon (DOC) loading to boreal lakes is being studied in lake Alinen Mustajärvi, a small humic lake in southern Finland, where labile DOC concentration has been artificially increased during 2008 and 2009 by monthly additions of cane sugar. As part of this wider project, in this thesis the responses of the zooplankton community to cane sugar addition were studied. Zooplankton samples were collected monthly in the ice-free periods of 2007, 2008 and 2009 and the mean densities and mean carbon biomasses of rotifers and crustacean zooplankton (cladocerans and copepods) were calculated. Stable isotope analyses (δ13C and δ15N) were made for …
