Vertaisarvioinnin harjoitusohjelma ja vertaisarviointien toteutus Ketosen väitöskirjassa
2021
Tämä materiaali on suomenkielinen kuvaus vertaisarviointi-intervention toteutuksesta Ketosen (2021) väitöskirjassa. Toteutus sisältää vertaisarvioinnin harjoituksia ja varsinaisia vertaisarviointeja. Interventio kesti 1,5 vuotta ja se toteutettiin fysiikan ja kemian oppiaineissa luokka-asteilla 7-8 vuosien 2018-2019 aikana. Harjoitukset ja vertaisarvioinnit on materiaalissa kuvattu siinä järjestyksessä, jossa ne tutkimuksessa toteutettiin. Interventio suunniteltiin vertaisarvioinnin aiempaa tutkimustietoa peruskoulun kontekstiin soveltaen. Materiaali toimii esimerkkinä siitä, miten vertaisarviointia voi harjoitella ja toteuttaa peruskoulussa osana oppiaineen opiskelua. This material is a de…
Game Mechanics in the Design of a Collaborative 3D Serious Game
2014
Background. This article investigates the potential of utilizing game mechanics in designing 3-D serious games for Computer-Supported Collaborative Learning (CSCL) and attempt to produce new information about designing collaborative serious games. Aim. This article has two aims: first, to clarify how theoretical knowledge of collaborative learning was related to game design in previous studies; and, second, to design a collaborative serious game based on theoretical knowledge of collaborative learning and game design. Results. The reviewed studies revealed the potential of using collaborative games in education. However, they showed that collaborative learning games were typically designed …
Argumentation in Secondary School Students' Structured and Unstructured Chat Discussions
2012
Joint construction of new knowledge demands that persons can express their statements in a convincing way and explore other people's arguments constructively. For this reason, more knowledge on different means to support collaborative argumentation is needed. This study clarifies whether structured interaction supports students' critical and elaborative argumentation. The study compares the quality of secondary school students' argumentation during structured and unstructured chat interaction. The data consist of 16 dyadic chat discussions: 8 discussions concerned vivisection and 8 gender equality. Half of the discussions were carried out through structured chat, and the other half through…
Synthesis of polymer materials for use as cell culture substrates
2007
International audience; Up to today, several techniques have been used to maintain cells in culture for studying many aspects of cell biology and physiology. More often, cell culture is dependent on proper anchorage of cells to the growth surface. Thus, poly-L-lysine, fibronectin or laminin are the most commonly used substrates. In this study, electrosynthesized biocompatible polymer films are proposed as an alternative to these standard substrates. The electrosynthesized polymers tested were polyethylenimine, polypropylenimme and polypyrrole. Then, the adhesion, proliferation and morphology of rat neuronal cell lines were investigated on these polymer substrates in an attempt to develop ne…
Two Decades of Progress in the Asymmetric Intramolecular aza-Michael Reaction.
2021
The asymmetric intramolecular aza-Michael reaction (IMAMR) is a very convenient strategy for the generation of heterocycles bearing nitrogen-substituted stereocenters. Due to the ubiquitous presence of these skeletons in natural products, the IMAMR has found widespread applications in the total synthesis of alkaloids and biologically relevant compounds. The development of asymmetric versions of the IMAMR are quite recent, most of them reported in this century. The fundamental advances in this field involve the use of organocatalysts. Chiral imidazolidinones, diaryl prolinol derivatives, Cinchone-derived primary amines and quaternary ammonium salts, and BINOL-derived phosphoric acids account…
Data Analytics in Healthcare: A Tertiary Study
2022
AbstractThe field of healthcare has seen a rapid increase in the applications of data analytics during the last decades. By utilizing different data analytic solutions, healthcare areas such as medical image analysis, disease recognition, outbreak monitoring, and clinical decision support have been automated to various degrees. Consequently, the intersection of healthcare and data analytics has received scientific attention to the point of numerous secondary studies. We analyze studies on healthcare data analytics, and provide a wide overview of the subject. This is a tertiary study, i.e., a systematic review of systematic reviews. We identified 45 systematic secondary studies on data analy…
Talent identification in soccer using a one-class support vector machine
2019
Abstract Identifying potential future elite athletes is important in many sporting events. The successful identification of potential future elite athletes at an early age would help to provide high-quality coaching and training environments in which to optimize their development. However, a large variety of different skills and qualities are needed to succeed in elite sports, making talent identification generally a complex and multifaceted problem. Due to the rarity of elite athletes, datasets are inherently imbalanced, making classical statistical inference difficult. Therefore, we approach talent identification as an anomaly detection problem. We trained a nonlinear one-class support ve…
The potential of temporal analysis: Combining log data and lag sequential analysis to investigate temporal differences between scaffolded and non-sca…
2020
This paper contributes to the ongoing discussion about analysing the temporal aspects of learning processes in the educational technology research field. Our main aim was to advance methods for analysing temporal aspects of technology-enhanced learning (TEL) processes by introducing the temporal lag sequential analysis (TLSA) technique and by combining TLSA with temporal log data analysis (TLDA). Our secondary aim was to illustrate the potential of these two analysis techniques to reveal the differences between the face-to-face technology-enhanced collaborative inquiry-based learning (CIBL) processes of three different conditions (non-scaffolded, writing scaffolded and script scaffolded gro…
Ammatillinen toimijuus työelämän muutosvirrassa.
2014
Työorganisaatioilta ja työntekijöiltä edellytetään jatkuvaa kehittymistä nykyajan työelämässä. Jatkuvan uudistamisen tuoksinnassa on oleellista pohtia ja tutkia, miten kehittäminen voi tapahtua kestävällä tavalla tukien yksilöiden aktiivista osallistumista, jaksamista ja identiteettityötä. Hallinnolliset määräykset ja ohjeistukset saattavat olla tehokkaita luomaan muutoksia työelämässä, mutta samalla uudistusten inhimilliset kärsimykset saattavat nousta liian suuriksi. – Katja Vähäsantasen väitöskirja Vocational teachers’ professional agency in the stream of change (Jyväskylän yliopisto 2013).
Geogebra-avusteinen tutkiva matematiikka opetusharjoittelussa : tutkimuksia opettajan ja oppilaiden toiminnasta
2011
Tässä artikkelikokoelmassa julkaistavat tutkimusraportit syntyivät osana johtamaani ”Tutkiva matematiikka opetusharjoittelussa” -projektia. Projektin tavoitteena on tarkastella tekijöitä, joista tutkiva matematiikan oppiminen muodostuu sekä kehittää ohjeistusta tutkivan matematiikan käytännön toteutukseen. Opetin matematiikan aineenopettajiksi opiskeleville kahdeksan 45 minuutin oppituntia tutkivan matematiikan periaatteita kurssilla ”OPEA411 Syventävä ainepedagogiikka”. Lisäksi kurssin ”OPEA611 Aineenopettaja työnsä tutkijana” 10 oppitunnin aikana perehdyimme tutkivaa matematiikkaa käsitteleviin tutkimuksiin, opetusta kehittämään pyrkiviin tutkimusmenetelmiin ja videoanalyysiin. Näistä 18 …
