Modeling of the N-terminal Section and the Lumenal Loop of Trimeric Light Harvesting Complex II (LHCII) by Using EPR

2015

The major light harvesting complex II (LHCII) of green plants plays a key role in the absorption of sunlight, the regulation of photosynthesis, and in preventing photodamage by excess light. The latter two functions are thought to involve the lumenal loop and the N-terminal domain. Their structure and mobility in an aqueous environment are only partially known. Electron paramagnetic resonance (EPR) has been used to measure the structure of these hydrophilic protein domains in detergent-solubilized LHCII. A new technique is introduced to prepare LHCII trimers in which only one monomer is spin-labeled. These heterogeneous trimers allow to measure intra-molecular distances within one LHCII mon…

Scaffolding self-regulated learning from causal-relations texts: Diagramming and self-assessment to improve metacomprehension accuracy?

2023

AbstractThe accuracy of students’ relative comprehension judgments when reading texts is typically rather low. This has been ascribed to students grounding their comprehension judgments on cues that are not diagnostic of their actual comprehension level. Asking students to complete causal diagrams—a diagramming scaffold—before judging comprehension has proved effective in providing them with more diagnostic cues and thereby fostered metacomprehension accuracy and self-regulated learning. However, there is still room for improvement. We investigated experimentally whether adding the instruction to students to self-assess their causal diagrams: (1) would lead to more accurate judgments than c…

Structural analysis of two foldamer-type oligoamides – the effect of hydrogen bonding on solvate formation, crystal structures and molecular conforma…

2012

Author's Final draft The crystal structures and molecular conformations of two foldamer-type oligoamides were analyzed. One polymorphic form and seven solvates were found for N¹,N³-bis(2-benzamidophenyl)benzene-1,3-dicarboxamide (the benzene variant), and two polymorphic forms and six solvates for N²,N⁶-bis(2-benzamidophenyl)pyridine-2,6-dicarboxamide (the pyridine variant). Three crystal structures of the benzene variant and seven structures of the pyridine variant were solved using single crystal X-ray diffraction. The crystal structures showed that the different modes of intramolecular hydrogen bonding strongly affect the conformation and folding of the molecules, which is most evidently…

Ohjaava opetuskeskustelu suomalaisella viittomakielellä : tapaustutkimus kuuron oppilaan matematiikan opetuksesta

2014

Suomalaisen viittomakielen pro gradu –työssäni tarkastelen kuuron oppilaan viittomakielistä opetusta vuorovaikutuksen näkökulmasta. Tutkimusaineisto koostuu kahdesta matematiikan yksilöopetustunnista. Tutkimuksen tavoitteena on ollut selvittää, millaisia muotoja ohjaava opetuskeskustelu saa kuuron oppilaan suomalaisella viittomakielellä toteutetussa opetuksessa. Tapaustutkimuksen kautta yksilöidään ja luokitellaan myös viittomakielisen ohjaavan opetuskeskustelun osatekijöitä. Tutkimusaineiston analyysi perustuu Vygotskyn (1978) sosiokulttuuriseen teoriaan ja siihen liittyviin käsitteisiin oppimisen oikea-aikainen tukeminen ja lähikehityksen vyöhyke. Videotaltiointien analy…

Pre-service teachers and guided inquiry-based science teaching with simulations

2017

The aim of this dissertation was explore the beliefs and practices of pre-service primary teachers on using simulations as a part of guided inquiry-based lessons. Even though research has shown that using simulations to learn science offers certain learning benefits compared to other forms of instruction, their use in Finnish schools is still rare compared to the international average. Teacher training has the potential to promote the use of simulations in primary classrooms. Internationally, research has been called for the role of teachers in learning and teaching with simulations. As a part of this dissertation, an intervention was designed to accustom a group of pre-service teachers to …

Mental rotation and mental folding in 7- and 8-year-old children

2016

Mielessä kääntäminen ja mielessä taittelu ovat avaruudellisten representaatioiden mielessä muuntamista. Mielessä kääntäminen muuttaa objektin suunnan, kun taas mielessä taittelussa täytyy kuvitella, miltä objekti näyttää taittamisen jälkeen. Taitoja on tutkittu paljon, mutta silti ei ole varmuutta, ovatko ne samanlaisia vai erilaisia prosesseja. Aiemmat tutkimukset ovat löytäneet yhteyden mielessä kääntämisen ja matematiikan taitojen välille, mutta mielessä taittelun yhteyttä matematiikkaan ei ole osoitettu. Kuitenkin, suurin osa tutkimuksesta on tehty aikuisilla, joten lasten mielessä muuntamisen taitoja ei ole tutkittu yhtä laajasti. Tässä tutkimuksessa tavoitteena oli tutkia mielessä kää…

Teaching Is a Story Whose First Page Matters : Teacher Counselling as Part of Teacher Growth

2022

The starting point of the study is the work counselling process taking place in the induction phase of the students’ teaching career. The work counselling process consists of activities that support and strengthen the students’ teacher hood and their primary function as teachers by helping them to analyse their work and to attach to working life as newly graduated teachers. In this study, we use contextualisation and storytelling in the frameworks of positive pedagogy and systems theory to reflect on the students’ growth process as teachers. We also acknowledge the importance of Vygotsky’s zone of proximal development and, related to that, timely learning support (scaffolding) and a solutio…
