ǂThe ǂrole of the stress axis in modulating behavioural flexibility in a social cichlid
Get PDFThe hypothalamic-pituitary-interrenal (HPI) axis or the stress axis – the hypothalamicpituitary-
adrenal (HPA) axis equivalent in fishes, is a major neuroendocrine system that
regulates the stress response and effects many body functions including cognition. Activity of
the axis is regulated by negative feedback induced by the release of glucocorticoids which bind
on glucocorticoid receptors in the brain to stop the further release of glucocorticoids. The stress
axis activity following acute stress is regulated via the lower affinity glucocorticoid receptors
which are found in high concentrations all over the pituitary and the brain. An acute rise with
a subsequent swift decline of glucocorticoid hormones induces an emergency response which
enhances cognitive performance. Although memory formation and attention, two important
building blocks of behavioural flexibility, are known to be influenced when exposed to
stressors, whether stress mediates behavioural flexibility is less investigated. The main
objective of this experiment was to investigate the role of the HPI axis in mediating behavioural
flexibility in the cooperatively breeding cichlid fish Neolamprologus pulcher in an ecologically
valid set-up in which the stress hormone cascade is dependent on the behavioural task under
study. To verify this role, we pharmacologically blocked glucocorticoid receptors in adults
using a non-invasive short-term application of a glucocorticoid antagonist mifepristone
(RU486). Subsequently after the application we repeatedly exposed test fish to an ecologically
relevant mild stressor and tested their behavioural flexibility in a detour task. The application
of mifepristone decreased behavioural flexibility in an ecologically relevant spatial task
without altering motivation to seek shelter. This highlights the role of the stress axis in
determining the ability of animals to adapt to changes in the environment and emphasises the
tight link between stress and cognition in general. This work is of particular relevance for
current conservation issues in a world where humans rapidly alter the environment
The experience of deciding to go jogging
Get PDF: Empirical sciences study decision-making predominantly from a third-person perspective and mostly in a laboratory setting. However, the mentioned approaches do not provide comprehensive insight into the decision-making process. What is missing is the first-person perspective of the decision-maker as well as the knowledge of how one experiences decision-making in everyday life. Similarly, within sport psychology and exercise psychology, there is a lack of qualitative research addressing the experience of processes related to physical activity. The aims of this master’s thesis are: to study how recreational joggers experience the decision-making process to go jogging, namely during episodes (i.e., in distinct moments of experience); and to examine how this experience is embedded in their everyday lives. In accordance with the aims, I carried out a study in an effort to contribute to our understanding of decision-making from the first-person perspective as it occurs in daily life. The data collection process was conducted using a micro-phenomenology-based method as well as the ethnographic method. Seven co-researchers – recreational joggers interested in exploring their own experience – participated in the study. They recorded episodes in which they were thinking about going jogging in the form of journal entries. These further served as the basis for six phenomenological interviews, with which I obtained descriptions of experience in the investigated episodes. Semi-structured interviews were conducted to study the context in which the episodes occurred. The data analysis was conducted following the qualitative data analysis approach and was carried out on three levels, namely by gradually combining experiential and ethnographic data. The results showed that the decision-making to go jogging in the episodes occurred on the basis of affective states, on the basis of rational judgment regarding the feasibility of going jogging, or the decision occurred spontaneously. The experience of the decision-making process to go jogging was embedded in the co-researchers' everyday lives based on their disposition towards jogging, of which there were three: jogging as a non-committal form of relaxation, jogging as a way of balancing productivity with current pleasures, and jogging as a way of life. With this master's thesis, I add to the body of knowledge about the experience of decision-making. Additionally, I emphasize the need to research experiential phenomena on multiple levels and by combining several methods to obtain a more holistic description of the studied phenomenon
Colour dimensions in intaglio printmaking
Get PDFMy Master thesis presents research work in the field of printmaking, with the intention of exploring colour as the main artistic theme. Colour is usually the primary theme in painting, but we can thoroughly and individually examine it within the sphere of intaglio printmaking as well. In the thesis I characterize and analyze the so-called colour dimensions – the key parameters that define expression of colour. I study colour’s characteristics and present the terms chromatic agent and chromatic effect. In the empiric part I present a printmaking series called Moon time, which contains 28 monochrome coloured prints. The series is divided into five colour segments: blue, green, red, yellow, and gray. I was interested in the way intaglio affects colour appearance, how the duration of etching affects the dimensions of colour, and how important is the choice of pigment
Analysis of the impact of physical exercise on balance development in the preschool years
Get PDFIn the diploma work we studied the effects of exercise on the development of balance in the preschool period. Through a review of Slovenian literature, we presented the holistic development of a preschool child, with special emphasis on motor development. Accordingly, we studied motor skills and specifically emphasized balance. Research on the development of balance in the preschool period has shown that balance training makes sense, as it is a sieve for all physical activities. Previous research on the topic of balance has emphasized the usefulness of including exercises for the development of balance, but we have not seen research on how long it takes to make noticeable progress.
The research we studied mostly found differences between two different age groups, but not differences within the same age group.
Therefore, in the diploma work we investigated whether 5 times a week of balance development activities in the range of 15 movement units has the same effect on the development of balance of children of the same age (4 to 5 years). The sample consisted of 36 children, half of whom were experimental and half of the control group. The sample of variables consisted of a movement program of 15 training units with systematic planning of balance development activities and three adjusted balance tests. All children were tested twice with three adjusted balance tests before and after the experiment. Half of the children, which we named the experimental group, received a systematic step-by-step movement program for the development of balance in the range of 15 exercises, the other children (control group) did not receive this program.
The obtained data were processed with the statistical program Excel. The t-test for independent samples was used to determine differences between the groups, and the pair t-test was used to determine progress within the experimental group. Hypotheses were accepted with a 5% level of statistical characterization. Analysis of the data obtained by the quasi-experiment indicated progress in the experimental group, which was also statistically significant
Teaching science and technology in primary school using slovenian educational videos during distance learning
Get PDFThe purpose of each teacher is to impart knowledge and approximate the learning objectives of science and technology to students by understanding and visualizing learning content. Many times are there educational science videos to help them with understanding. Science and technology curriculum gives teachers the opportunity to achieve learning goals for example through use of multimedia materials (text, audio and video, animations and interactive displays). Each teacher decides for himself how it will diversify and illustrate consideration of a new lesson as it all depends on the students and their perceptual senses. In any case, multimedia can contribute to more fun lessons and higher motivation of students. It was a great help in the years 2020 and 2021 at the emergence of a not so common form of education, in distance learning. The purpose of the research in the master's thesis will determine whether teachers have used educational videos in distance learning, in which learning contents and how well they provided such qualitative lessons.
We conducted a qualitative survey that included 16 teachers, who teach subject science and technology in the 4th and 5th grade of primary school. Of all these teachers there were 15 women and one man; 37.5 % of teachers teaching in 4th grade and 62.5 % teaching in 5th grade.
The results of qualitative survey show that teachers in distance learning used Slovenian educational videos, they recorded their own videos and prepare lessons alongside videos. All teachers answered that they professionally review the correctness of videos. Teachers mention YouTube, Slovenian web page RTV SLO (Izodrom and Infodrom) and Arnes online classroom video portal as the most often used web page for searching videos. Some teachers had an access to interactive materials through textbook, where they searched videos for science lessons. Distance learning classes took place differently as in the classroom, but the teachers say that now, according to this experience, they use videos more often in the classroom, because the set of them is larger and the quality is verified.
With our master's thesis, we offer primary teachers an insight into its use of Slovenian educational videos in science and technology classes at distance learning. The knowledge we have contributed can be a confirmation for teachers of a good-conducted lessons during the distance learning and motivation for further preparation of lessons with Slovene science videos
Pupils' interest in topics of physics outside of school frames
Get PDFPhysics in Slovenian primary schools is considered an unpopular subject. Pupils find it uninteresting and useless. They believe that the popularity of physics is strongly influenced by the choice of topic, covered in class. They wish to learn about modern physics findings in regular physics classes. In the prospect of lifelong learning and actuality implementing modern physics findings in physics lessons makes sense. The goal of our research was to (1) find out, which topics that are not mentioned at lessons concerning physics pupils find interesting, (2) do pupils wish to learn about modern physics findings, (3) would they like to learn about modern physics findings as a part of optional subject, (4) do gender or (5) interest in natural science influences the choice of topics, which pupils find interesting and (6) what are pupils' responses on school lessons about radioactivity regarding interest and new knowledge about physics. In order to carry out our research we have designed and implemented two lessons, developed two questionnaires and a test of knowledge. 136 pupils of 8th and 9th grade pupils of a particular primary school in Slovenia took part in our survey. 16 of them participated in knowledge testing. Gathered data was statistically analyzed. Out of seven proposed topics, covering various modern physics findings radioactivity was found the most interesting. Most pupils wish to learn about modern physics findings, whereas one of three wish to partake in an optional subject regarding modern physics findings. There are differences in which topics female or male pupils find interesting. In addition, there are differences in how interesting pupils with different level of interest in natural science find topics regarding modern physics findings. Pupils found school lessons on radioactivity interesting. They made physics more interesting and improved pupils' interest in physics
Pre-literacy skills in preschool children
Get PDFThe development of emerging literacy is crucial in the pre-school period. It is influenced by several different factors. Already in the pre-school period, the educator can identify risk factors that indicate the possibility of later development of specific learning difficulties and offer the child appropriate support and assistance.
Poorly acquired or unfamiliar pre-literacy skills often indicate specific learning difficulties, which are most evident when a child enters school. They are often accompanied by learning failure, which can negatively affect the child.
In the theoretical part of the thesis, I wrote about the development of pre-literacy skills in the preschool period. Various authors (Grginič, 2008, Končnik Goršič, Kavkler, 2002, Marjanovič Umek, 2010, Prgić, 2018 and others) find that they have a significant impact on children's literacy. Poorly developed pre-literacy skills, including: behavior, motor skills, language comprehension, verbal expression, metacognition, other cognitive activities, pre-literacy, pre-mathematics, etc., may indicate the later development of specific learning difficulties.
In the empirical part, I found out how many children show deviations in individual areas with the help of the IPDA questionnaire (Terreni, Tretti, et al., 2011), which can help educators to identify areas of pre-literacy skills in which a child may have problems in preschool. I wanted to find out whether there are differences between girls and boys in the field of pre-literacy skills and whether there are deviations between individual areas of pre-literacy skills. The sample included 65 children from Kranj kindergartens aged 5-6 years.
I found that 4 children (6.2%) have the highest chances of developing specific learning difficulties later. The results of the research also showed that there are no differences between girls and boys in the field of pre-literacy skills, but there are discrepancies between individual areas of pre-literacy skills

Using the iNaturalist app in biological research and education
Get PDFIntroduction: iNaturalist is an application for the detection and identification of organisms and communication between users, aimed at both amateur and professional scientists. Aim: This master thesis should give an insight into the usefulness of the application in education and research through different methods. Methods: We used a few different methods in this research. Through various article search engines – Nature, Scopus, Web of Science, and Google Scholar – we searched for research papers that used the iNaturalist app in the classroom environment. The articles found were then reviewed and a cross-section of methods and results obtained by foreign researchers was created. Another method was to test the usage of the app in school. We took advantage of the school's participation in the Forgenius project, which focused on gaining insights into the diversity of European forests and their resilience to climate change – here we saw great potential for using the iNaturalist app. The app was then implemented in another elementary school, where we adapted the way of working according to feedback from teachers, students and pupils who were present during the first implementation. The third method was to review the observations recorded in Slovenia – in this way we gained insight into the groups of organisms most commonly observed by users in our country. The last, fourth method was an interview. We selected a group of users who have recorded observations of organisms of the genus Mantis since the application was created. We contacted these users through the iNaturalist website and invited them to participate in an interview where we obtained information about their education, hobbies, occupation, and how they record and determine data. Results: In total, we found 13 unique searches about the use of the iNaturalist application in education on various article search engines. We found that a common method of use was conducting BioBlitz’s and using the application with students to increase knowledge of taxonomy and improve attitudes toward nature. Awareness of the importance of biodiversity was also frequently promoted. We were successful in our attempts to use the app in a school setting. The application was interesting for both students and teachers. During the activity, students acquired new knowledge about the names of plants and other organisms, and some students indicated that they would like to use the app outside of the school context. For the third objective, we collected data on species recorded in Slovenia. We found that over 60,000 observations had been recorded in Slovenia by April 2022, more than half of which were marked “research grade”. We also found that the observations concerned over 5,300 species, among which plants and insects predominate. In the last objective, where we gained insight into users recording representatives of the order of praying mantis, we found that users mainly used the application as a method to store their observations and deepen their knowledge. In most cases, respondents were invited to use the app by an acquaintance, and we also found that the vast majority used biological keys and other tools to identify organisms. Discussion and Conclusion: iNaturalist is an application that is rapidly gaining traction for both professionals and laypeople. The number of research papers investigating the educational benefits of the application is increasing, although the number of articles is still too small. The authors of the articles often focus on events such as the BioBlitz, since these are already an established practice to which it is very convenient and efficient to add an ICT aspect. It might be smart to consider the usefulness of the application in the school context and advise teachers on how and where to incorporate it into their learning process. We see that the use of technology in the classroom is attractive and often used "just because it is new." Of course, teachers need to ask themselves where it makes sense and where it does not, and a set of materials will greatly help them in these decisions and planning. iNaturalist already has some materials and tips for teachers on their website, but most of them are written in English. With this application we can bring a lot of good into the classroom, both in knowledge and in stimulating the emotional side of the students. The current state of biodiversity and climate change shows us how important it is that we change our behaviour, and the easiest place to start is with our children. Encouraging them to develop positive feelings towards nature and natural diversity is one of the first steps we can take towards a better and more sustainable environment
