Enhancing Pre-service Elementary Teachers' Conceptual Understanding of Solution Chemistry with Conceptual Change Text

This paper reports on the use of a constructivist-based pedagogy to enhance understanding of some features of solution chemistry. Pre-service science teacher trainees' prior knowledge about the dissolution of salts and sugar in water were elicited by the use of a simple diagnostic tool. The test revealed widespread alternative conceptions. These evaluation data were used to produce two segments of ‘conceptual change text’: concise summaries that present alternative and scientific conceptualizations for the concepts under study. The texts were administered to 21 pre-service elementary trainee teachers whose understandings of number of conceptions were subsequently re-evaluated employing a pre-test post-test approach in which their answers and reasons for their answers were solicited. The findings suggest that these pre-service elementary trainees' alternative conceptions are changed to become more in accord with the scientific view, with more participants providing correct answers along with correct reasons than before the intervention. This work suggests that the use of conceptual change text may provide a simple and cost and resource-effective way to aid conceptual understanding for the dissolution of ionic solids in water including the effect of solute surface on the dissolution process.     

A Politically Liberal Conception of Formal Education in a Developing Democracy

As discussed by John Rawls, in a well-ordered society, a public political culture’s wide educational role bears the primary responsibility for developing reasonable individuals for the stability of a politically liberal society. Rawlsian scholars have also focused on the stability and enhancement of developed liberal democratic societies by means of those societies’ education systems. In this sense, one thing that is common to Rawlsian scholars’ and Rawls’s own understanding of the role of education appears to be a concern over the stability of a politically liberal society since it is highly dependent on the character of its citizens. Also, it is usually believed that a politically liberal account of education can be implemented in a developed politically liberal society. In contrast, this study discusses the possibility of implementing a politically liberal account of education in a developing liberal society that may become a developed liberal democracy under an overlapping consensus.     

Students' increased time spent on social media,and their level of coronavirus anxiety during the pandemic,predict increased social media addiction

Background

During the COVID-19 pandemic period, the level of anxiety and the duration of social media use increased in university students.

Objectives

This study aimed to examine the relationship between coronavirus anxiety and social media addiction in university students.

Methods

The sample consisted of 346 university students in Turkey. The data were collected online using the Sociodemographic Data Form, the Coronavirus Anxiety Scale Short Form and the Social Network Addiction Scale. The data were analysed using one-way analysis of variance, Mann–Whitney U test, Pearson correlation analysis, chi-square analysis and multiple linear regression analysis.

Results

The results showed that the mean coronavirus anxiety score was higher in men than in women. Social media addiction increased as the daily time spent by the students on social media increased. A positive correlation was found between the daily time spent on social media before the pandemic and social media usage during the pandemic. It was concluded that students use social media more during the pandemic than before it and that social media addiction increases as the students' coronavirus anxiety increases.

Conclusion

It is important to plan initiatives to reduce coronavirus anxiety to prevent social media addiction in young people.

Study Location and Sample

The research population consisted of 1st and 2nd year students who are studying in the Medical Services and Techniques Department of Vocational School of Health Services at a university located in the west of Turkey, during the Fall Term of academic year 2020–2021. Students in this department are studying in anaesthesia, dialysis, first and emergency aid, medical laboratory techniques, medical imaging technique, and medical documentation and secretarial programmes.     

Harem education and heterotopic imagination

Education can cease to be a showcase for political projects and start serving women’s lives only when the agency of women in their own education is acknowledged. In this paper I have addressed issues concerning harem education to emphasise that possible solutions to issues of girls’ education require an awareness concerning the history of girls’ education in different geographies. In this article, this agency is pursued in the homosocial production of knowledge in the harem, which is an exoticised space. Questioning the limitations and benefits of the concept of the harem is especially important in understanding processes such as the accommodation of public practices of education in women’s homes. Using Foucault’s concept of heterotopia, the harem is contextualised to shed light upon its liberating and dominating aspects, as a sphere where public and private practices of education converge.

Validation of the Career Adapt-Abilities Scale–Short Form across different age groups in the Turkish context

A short 12-item version of the Career Adapt-Abilities Scale–Short Form (CAAS-SF) was validated across three different age groups in the Turkish context. Scale scores demonstrated adequate to high internal consistency and 4-week test–retest reliability, good fit with the original four-factor model, factorial invariance across gender and age groups, strong convergence with the 24-item version, negative associations with trait anxiety and work stress, and positive associations with career decision self-efficacy. It was concluded that the Turkish version of the CAAS-SF appears to be a valid and reliable measure for assessing career adaptability and using it in career education and counseling process.     

Children’s epistemological views according to their learning centre preferences

The purpose of the study was to investigate children’s epistemological beliefs in terms of their free play preferences in relation to learning centres. The study was conducted with 115 children coming from families with high socio-economic status (54 girls and 61 boys, 57 five years old and 58 six years old) during the 2015/2016 spring semester. The Epistemological Beliefs Scale for Children was administered to each child individually. In addition, all the children were shown pictures of science, drama, music, literacy, painting and mathematic centres prepared by two researchers and asked to choose the one they preferred for play during free time. Each child was interviewed by one researcher and each interview lasted approximately 15–20 minutes. According to the overall results of the study, children’s epistemological views tended to be dogmatic; however, some children thought more sceptically. Furthermore, children had a sophisticated thinking style in certain dimensions of knowledge while having immature reasoning in others. It was also found that the source of knowledge and hypothesising sub-dimensions of epistemological views indicated dogmatic thoughts. On the other hand, children had sceptical thoughts concerning the sub-dimension of change in knowledge.     

Analyzing digital divide within and between member and candidate countries o f European Union

The main purpose of this study is to analyze whether a digital divide exists among European Union (EU) members, new members, and candidate countries. Beyond this, the second goal is to find out if a digital divide has a significant association with the process of becoming an EU member. First, member, new member, and candidate countries are classified into three groups, and MANOVA (Multivariate Analysis of Variance) is applied to determine differences among these groups in terms of Information Society levels. Then, Information Society variables are analyzed using Discriminant Analysis. According to the results of the research, there is a significant level of digital divide in the EU and a certain information society level currently is not associated with EU membership. The EU must address the digital divide among member countries if they are to become a close-knit community, and to continue to be one of the most competitive economic powers in the world. Finaly, the EU might consider using information society level as an objective criteria along with other objective and subjective criteria currently being used as EU membership criteria.     

Information retention’s relationships with flow,presence and engagement in guided 3D virtual environments

The purpose of this study was to examine the correlation of different variables with information retention in guided 3D virtual learning environments by employing three experimental designs. In each experiments, different participants were included in the same population and different variables were considered. Information retention test, flow, presence, engagement scales were used as data collection tools. Namely measures of flow, presence and engagement were examined to see their correlation with retention in experiment 1, 2 and 3. As a result, not the total score of flow but focused attention, enjoyment and skill dimensions has a weak but significant correlation with information retention, while the challenge has a moderate and significant negative correlation. In the second experiment, retention had a significant, low-level relationship with teaching presence and cognitive presence, but it did not have a similar relationship with social presence. In the third experiment, information retention significantly correlated with affective and cognitive engagement, but not with behavioral engagement. Although the three studies’ participants were from the same population, It was seen that the differences in the level of relationship between information retention and the variables studied in each study. Nevertheless, it was found that the levels of flow, presence and engagement of students are important for information retention in a guided 3D virtual learning environment. The study is thought to guide researchers to design 3D virtual learning environments for different purposes, considering these variables.
