Background STEM education has experienced significant growth due to its pivotal role in innovation and economic development. While cognitive factors like prior knowledge are known predictors of STEM success, non-cognitive factors, including attitudes and demographics, also play vital roles. However, there is a notable scarcity of research focusing...

The relationship between use of social networking sites (SNS) and mental health varies acrosspersons. However, which user characteristics explain this variance? To examine how this issue has been studied in the literature, we conducted a systematic review. We provide an overview of (a) user characteristics that have been examined as moderators of t...

Estonian students achieved high scores in the latest Programme for International Student Assessment surveys. At the same time, there needs to be more knowledge about the teachers guiding these students, as this could provide insights into effective teaching methods that can be replicated in other educational contexts. According to the Teaching and...

While the excessive use of social media is associated with many difficulties in daily life (including mental health problems), the topic can be overemphasised in the media, and there is no reason to consider social media use in itself as the root cause of problems in daily life.

This large, international dataset contains survey responses from N = 12,570 students from 100 universities in 35 countries, collected in 21 languages. We measured anxieties (statistics, mathematics, test, trait, social interaction, performance, creativity, intolerance of uncertainty, and fear of negative evaluation), self-efficacy, persistence, and...

Background Research on the relationship between Facebook use intensity and depressive symptoms has resulted in mixed findings. In contrast, problematic Facebook use has been found to be a robust predictor of depressive symptoms. This suggests that when intense Facebook use results in a problematic usage pattern, it may indirectly predict depressive...

Problematic use of social networking sites (SNS) has a negative impact on mental health. It has been found that people who score high on neuroticism are especially vulnerable towards engaging with SNS in a problematic way but it is not clear which psychological mechanisms explain this relationship. We addressed this issue by examining the mediating...

The role of epistemic beliefs in science (EBS) and socio-economic status (SES) on mathematics and science test results on both student- and school-level data was investigated via a secondary analysis of Estonian Programme for International Student Assessment (PISA) 2015 survey data. The effective sample comprised 3991 students (52% girls, 48% boys)...

Test-taking motivation (TTM) has been associated with test performance in low-stakes testing contexts. However, there have been few studies about TTM in high-stakes testing contexts, and these have contradictory results. Our aim was to explore the relationship between test-taking effort and test performance in a real-life high-stakes testing contex...

Background. The excessive use of Internet-based technologies has received a considerable attention over the past years. Despite this, there is relatively little research on how general Internet usage patterns at and outside of school as well as on weekends may be associated with mathematics achievement. Moreover, only a handful of studies have impl...

Background Although mathematics anxiety and self-efficacy are relatively well-researched, there are several uninvestigated terrains. In particular, there is little research on how mathematics anxiety and mathematics self-efficacy are associated with deep (more comprehensive) and surface (more superficial) approaches to learning among STEM and socia...

It has been shown that both fear of missing out (FoMO) and problematic (i.e., excessive) smartphone use (PSU) are negatively associated with indicators of emotional well-being. Moreover, FoMO has been found to be a key predictor of PSU. This suggests that PSU may mediate the relation between FoMO and decreased emotional well-being but this pathway...

Now the two researchers independently assessed 30 randomly chosen articles. An identical decision was reached on 83% of the abstracts, Linear Weighted Kappa was .645 (ASE = 0.131, Z = 4.430, p < .001, 95% Asymptomatic CI [...

Due to the rise of social networking sites (SNSs), social comparisons take place at an unprecedented rate and scale. There is a growing concern that these online social comparisons negatively impact people’s subjective well-being (SWB). In this paper, we review research on (a) the antecedents of social comparisons on SNSs, (b) the consequences of s...

Passive Facebook use, which involves engaging in non-socially orientated behavior on the popular social networking site, is associated with a range of negative outcomes, including social anxiety, loneliness, jealousy, and depressed mood. Research indicates that passive Facebook use may also be related to a tendency to engage in social comparison wi...

Problematic smartphone use (PSU) has been consistently shown to relate to dysfunctional behaviors and negative daily life outcomes, including in academic context. One explanatory factor could be procrastination - yet it has not been studied how procrastination is related to PSU. The aim of this research was to study that relationship. Participants...

Neural adhesion proteins are crucial in the development and maintenance of functional neural connectivity. Growing evidence suggests that the IgLON family of neural adhesion molecules LSAMP, NTM, NEGR1, and OPCML are important candidates in forming the susceptibility to schizophrenia (SCZ). IgLON proteins have been shown to be involved in neurite o...

Several studies have shown that problematic smartphone use (PSU) is related to detrimental outcomes, such as worse psychological well-being, higher cognitive distraction, and poorer academic outcomes. In addition, many studies have shown that PSU is strongly related to social media use. Despite this, the relationships between PSU, as well as the fr...

Although the literature has paid a lot of attention to the importance of mobile digital media in shaping people’s perception of personal and social time, little empirical research has focused on these issues. We aim at bridging this gap by testing empirically a hypothesis that shared perceptions of the social life in the smartphone era vary generat...

Education is an area where various information and communication technologies (ICT), including the Internet, can be applied. Students and teachers often make use of ICTs in order to seek out information online. Students make use of online platforms to complete their homework, and to communicate with one another. ICTs are also used by students and t...

Teacher education and a career in teaching is not a popular career choice among young people in Estonia; as a result, there is policy interest in improving the attractiveness of teaching and better understanding the factors that influence people to choose it. This chapter examines changes in motivations and perceptions among teacher education stude...

Many studies of teacher motivation have been conducted in different contexts over time. However, until fairly recently there has not been a reliable measure available to allow comparisons across samples and settings. This has resulted in an abundance of findings which cannot be directly compared or synthesised. The FIT-Choice instrument offers the...

The aim of this paper is to develop a shorter version of the Estonian Smartphone Addiction Proneness Scale based on previous works (e.g., Ching et al., 2015; Kwon, Lee, et al., 2013; Rozgonjuk, Rosenvald, & Täht, 2016). Seven hundred and sixty-seven people participated in the study (Mage = 26.10 ± 6.73 years; 22% male), for which they completed the...

This paper investigates the relationship between educational achievement and the motivation to learn. We used the 2006 Programme for International Student Assessment (PISA) that contains representative samples from 55 nations. A strong negative correlation between educational achievement and motivation toward science learning emerged at the nationa...

Over the years, researchers have used several methods to investigate reflection. These are based on various theories. Researchers mainly use qualitative methods to study reflection, but mixed methods and quantitative studies are carried out as well. A number of different scales have been developed and used to measure reflection. The main purpose of...

We studied how time measures can be used as predictors of test-taking performance in low-stakes tests. Our sample consisted of undergraduate students (N = 327) who took a computer-based cognitive abilities test. Our aim was to find how test-takers' motivation manifests itself in test-taking effort. We found that a high test-taking speed is related...

The main purpose of this study is to explore which students of Estonian higher education institutions are willing to take low-stakes tests which have no direct consequences for them. Altogether 603 first-year undergraduates from different institutions of higher education participated in the study - 46.3 per cent of them took the low-stakes cognitiv...

Abstract: At the end of the 90s, Lynn knew that men have higher abilities and SAT scores. However, why then did females have higher grades in college? Analysing national databases and relevant literature, he concluded that the reason is in higher work ethics of females. Lynn has analysed science achievement in large international studies. Males wer...

We estimated the invariance of educational achievement (EA) and learning attitudes (LA) measures across nations. A multi-group confirmatory factor analysis was used to estimate the invariance of educational achievement and learning attitudes across 55 nations (Programme for International Student Assessment [PISA] 2006 data, N = 354,203). The constr...

The model for relationships between general educational performance (GEP) and non-cognitive characteristics (e.g. students' self-evaluation and motivation in science), was worked out previously on Estonian data (Täht and Must 2009). The aim of this paper was to fit the model on the data of four neighbouring countries. The analyses showed that Eston...
