Influence effect of an external electric field and dissipative tunneling on intracenter optical transitions in quantum molecules with D2- states

2020

In the zero-range potential model and in the effective mass approximation, dispersion equations have been obtained, that describe dependence of the average binding energies of the quasistationary g- and u-states of the D − 2 - center in the QD, as well as the widths of energy levels on the magnitude of the external electric field and the parameters of 1D-dissipative tunneling. Dips in the field dependences of the binding energies average values for quasi-stationary g- and u-states have been revealed. It is shown that the field dependences of the energy level widths for the g- and u- states of the D − 2 -center have a resonance structure at the external electric field strengths corresponding…

Kuvitellut Pohjoismaat Viron presidenttien puheissa

2017

Pohjoismaisuus on ollut oleellinen osa Viron kuulumisen politiikkaa viimeisen parinkymmenen vuoden aikana. Artikkeli analysoi, miten ja missä tarkoituksessa maan kolme presidenttiä asemoivat puheissaan Viroa suhteessa Pohjoismaihin vuosina 1992–2016. Tulokset osoittavat, että pohjoismaisuus saa kuulumisen politiikassa moninaisia muotoja: Pohjoismaihin kuulumisen, sen rajalla tai naapurissa olemisen lisäksi aineistossa uudelleen määritellään myös Pohjoismaat yhteisönä visioimalla Itämeren alueelle sijoittuvaa dynaamista ja kehittyvää Pohjola-Baltia-kokonaisuutta.

SQL Education

2020

Structured Query Language (SQL) skills are crucial in software engineering and computer science. However, teaching SQL effectively requires both pedagogical skill and considerable knowledge of the language. Educators and scholars have proposed numerous considerations for the betterment of SQL education, yet these considerations may be too numerous and scattered among different fora for educators to find and internalize, as no systematic mappings or literature reviews regarding SQL education have been conducted. The two main goals of this mapping study are to provide an overview of educational SQL research topics, research types, and publication fora, and to collect and propagate SQL teachi…

Enhancing Digital Skills of Early Childhood Teachers Through Online Science, Technology, Engineering, Art, Math Training Programs in Estonia

2022

Teacher professional development programs, including mid- and long-term Science, Technology, Engineering, Art, Math (STEAM) courses, have recently moved from in person learning at university premises to an online environment. Whether it is a temporary change in learning methods caused by the COVID-19 restrictions or whether it will become a new normal is currently under discussion in many teacher training institutions around the world. The aim of this study was to design and implement time- and money-saving synchronous online teacher training format for conducting co-design courses for early childhood teachers in the theme of STEAM integrated learning activities. Based on Tallinn University…

A Performance-Based Test for Assessing Students’ Online Inquiry Competences in Schools

2018

In this paper, we introduce a performance-based test for measuring adolescents’ competences in online inquiry. The test covers four competence dimensions: (1) searching and selecting relevant sources, (2) identifying the main ideas presented in the sources, (3) evaluating the credibility of the sources, and (4) synthesizing information across the sources. We implement a technological solution called NEURONE to carry out this routine. The scoring of the test data is demonstrated by presenting preliminary results of a case study. Finally, we discuss the strengths and limitations of the test.

The development of secondary students’ feedback literacy: Peer assessment as an intervention

2020

A growing body of research has recognized the importance of students’ having active roles in feedback processes. Feedback literacy refers to students’ understandings of and participation in feedback processes, and research on students’ feedback literacy has so far focused on higher education; secondary schools have not received attention. This case study investigates secondary students’ feedback literacy and its development in the context of formative peer assessment. From various data sources, three categories of students’ feedback literacy were identified, and criteria for the levels of literacy in each category were created. The criteria were used in the coding of seventh- and eighth-gra…

Citing as a sourcing practice: students’ citing self-selected online sources in their essays (Las citas como práctica del uso de las fuentes: las cit…

2020

This study examined upper secondary school students’ citations of self-selected online sources in their essays. Students (n = 140) conducted online inquiry about either effects of social media on people’s quality of life (SM) or allowance of genetic manipulation of organisms (GMO). Students, working either individually or in pairs, explored online sources with the help of a graphic organizer, after which they composed their essays. To capture the quality of citations identified in the essays, they were evaluated in terms of accuracy and richness of source features. Further, regression analysis was used to examine the effect of topic, grade level and work mode on the number and quality of ci…
