Retraction Note: Developing emotional intelligence in student teachers in universities

Emotional intelligence is a relatively new concept. Hence, it appears crucial to investigate its short-term and long-term effect on educational process. The primary aim of this study is to identify how teaching emotional intelligence affects the emotional competence of social pedagogue students by measuring their levels of emotional intelligence before and after training. For this, the Hall Emotional Intelligence Test was used. The focus lies on these aspects of emotional intelligence (emotional competencies): Emotional Awareness, Managing your Emotions, Self-motivation, Empathy, and Managing the Emotions of Other People. The results demonstrate a substantial improvement in all these measures. The present findings may be valuable for further research on emotional intelligence in education. In addition, the paper proves that raising teacher’s emotional intelligence is beneficial to teaching and learning.

Introduction E ducation quality and its improvement have always been an acute issue. For many years, specialists in this area have been concerned with developing education programs and teacher competencies, including their ability to organize the educational process properly. Meantime, emotional intelligence was often neglected as an individual quality. It is not a surprise though because the study of emotional intelligence is relatively recent in psychology. Despite the novelty of this notion, experts quickly appreciated the significance of the concept that it describes (Schoeps et al., 2019).
Emotional intelligence encompasses a vast array of skills and abilities. They span from the ability to understand, perceive, and classify emotions to the capability to express, regulate and manage them (Hughes et al., 2005). Some researchers proposed a hierarchical model (Palomera et al., 2008) of emotional intelligence, which includes four dimensions. The first dimension is emotional perception, followed by emotional integration (i.e., the ability to use emotions in cognitive thinking). The other two dimensions revolve around understanding (i.e., the ability to determine why and how emotions arise) and managing emotions (i.e., self-control and openness to emotional growth).
Among the main factors influencing emotional intelligence formation and functioning are aspects hardly dependent on the field of its interaction with the environment. From the perspective of the connection between a group of people for the purpose of providing a certain service in the context of market relations, four general attributes of emotional intelligence are outlined: selfawareness, self-management, social awareness, and social/relationship management. They are proven to contribute to emotional well-being among individuals and enhance the ability to practice in ways that will benefit students, families, colleagues, and other individuals (Raghubir, 2018). As a consequence, the study of emotional intelligence as a part of future teachers' preparation is significant in view of its direct impact on the health, relationships, and work/academic success of students (Kotsou et al., 2019).
A high level of emotional intelligence is essential for people employed in the social field. Why? The answer is simple. Without understanding, sharing and exerting control over other people's emotional state, it is not possible to build successful communication (Larina, 2016). Another domain where emotional intelligence is of high importance is education. The personality of a student develops while they obtain education. Hence, if we want to create a harmonious and conscious society, it is sensible to start developing emotional intelligence within the walls of educational establishments. Yet, only an emotionally competent teacher can handle this mission (Poulou, 2016).
Some studies show that high levels of emotional intelligence contribute to better discipline during class. It means that with an emotionally competent teacher taking charge in the classroom, students will better assimilate knowledge. Beyond that, they will be more engaged in learning, which will contribute more towards the high academic performance of the group (Di Fabio et al., 2016).
Literature review. Every year, more and more specialists are investigating the significance of emotional intelligence. Many appear to associate teacher's emotional competence with their ability to organize the educational process successfully (Petrides et al., 2016). One example is the article entitled 'The relationship between teachers' emotional intelligence and classroom discipline management' (Valente et al., 2019). The authors of that work concluded that an emotionally intelligent teacher presents greater discipline management. A teacher who presents emotional perception and expression skills easily perceives the emotional state of students and adapts their behavior. Hence, they can change the activity within the class when they understand that the students are demotivated. Another study reveals a connection between emotional intelligence ability and teacher efficacy, labeling the two of them as fundamental characteristics of a teacher (Valente et al., 2020). The authors argue that teaching is an activity that causes significant emotional workload and thus requires a teacher to possess sensitivity and knowledge of how to optimize the quality of interpersonal relationships with their students. It once again emphasizes how important the teachers' emotional intelligence is. The research defines teacher efficacy as teachers' ability to engage students in academic work, even when they seem problematic or indifferent (Valente et al., 2020). A similar topic was raised in the work entitled 'Emotional intelligence and job performance oh high school female teachers' (Latif et al., 2017). The authors found that emotional intelligence, besides other skills and attributes, is a crucial indicator of potential job performance. Other studies hold that emotional intelligence protects teachers against emotional burnout (Larina, 2017). Hence, experienced university teachers will most like better understand themselves and their students, build harmonious relationships, and organize the class efficiently (Mérida-López and Extremera, 2017).
Of course, emotional intelligence is essential for any individual. Scientists found that emotional responses come before the cognitive ones, which makes it vital to understand and correctly interpret one's emotional states. This ability will help a person make the right decisions, get to know himself, and reduce the influence of negative factors (Sangeetha, 2017). At the same time, accepting one's own emotions contributes to a better understanding of the thoughts and actions of others (Edannur, 2010). A person with high emotional intelligence knows how to build effective communication and friendly relationships with other people.
Problem statement. It is necessary to investigate the role of teachers' emotional intelligence in higher educational institutions to improve the quality of education. Despite the abundance of research papers on this topic, many issues are not fully disclosed (Mpofu et al., 2017). The novelty of the present study is that it estimates the effectiveness of emotional intelligence training among teachers. Through analyzing statistical data obtained during the study, this paper draws conclusions regarding the factors affecting teachers' emotional competence. The primary aim of this work is to identify how teaching emotional intelligence has affected the emotional competence of teachers. The objectives of the study are (1) to measure emotional intelligence of social pedagogue students enrolled in a higher educational institution (university); (2) to enhance the emotional intelligence of these students; (3) and to re-assess them after training to identify the difference (if any).

Methods
Sample. The random sample includes 40 social pedagogue students from the L.N. Gumilyov Eurasian National University in the city of Nur-Sultan and 46 social pedagogue students from the K. Zhubanov Aktobe Regional University in the city of Aktobe.
Research design. Emotional intelligence was measured using the Hall Emotional Intelligence Test (EQ test), one of the most famous techniques (Ilyin, 2001). The turn to this method was due to its widespread application and its comprehensive approach to assessing emotional intelligence in terms of five dimensions. The test offers 30 statements (Appendix 1), which somehow reflect the different aspects of one's life. Respondents were asked to rate their agreement with each statement using a 6-point scale. Hence, 'Completely disagree' gets −3 points, 'Mostly disagree' gets −2 points, 'Partly disagree' is worth −1 point, 'Partly agree' gets +1 point, 'Mostly agree' gets +2 points; and 'Completely agree' equals +3 points. The total score is the sum of all responses. Because emotional intelligence encompasses many aspects, this test evaluates it from different angles. The questionnaire has five scales: Emotional Awareness (items 1, 2, 4, 17, 19, and 25), Managing your Emotions (items 3, 7, 8, 10, 18, and 30), Selfmotivation (items 5,6,13,14,16,and 22),Empathy (items 9,11,20,21,23,and 28), and Managing the Emotions of Other People (items 12, 15, 24, 26, 27, and 29). The score of each scale is the sum of points received for all items within the scale. The greater the positive score, the higher the examined ability. According to the scales' gradation, high level of emotional intelligence corresponded to the total score exceeding 70, an average-to a score from 40 to 69, and a low-to a score of <39.
After the survey, all subjects underwent emotional intelligence training (Mayer and Salovey, 1995). The training program had four thematic blocks ( Fig. 1): Perceiving emotions, Facilitating through with emotions, Understanding emotions, and Managing emotions, both one's own and those of others.
The exercises within the program are meant to raise the awareness of one's emotional behavior in students and develop their ability to identify, understand, and manage one's emotions. These abilities will help to build successful communication with others.
Block I consists of exercises for identifying emotions. First, students learn how to give qualitative and quantitative feedback on their emotional state. Afterwards, they estimate the emotions of others.
Block II focuses on teaching how to use emotions to facilitate thinking (emotional facilitation). Participants were asked to rate the frequency of physical sensations they experienced when in specific emotional state. For example, wide eyes and open mouth signal surprise, while a feeling of coolness in the body signals disappointment.
Block III is a combination of theory and practice. The theoretical part begins with a description of the basic emotions: fear, joy, sadness, disgust, anger and surprise. Description of each emotion comes with a schematic illustration depicting three intensity levels of facial expression. The summary table conveys the causes, typical physical manifestations and thoughts usually associated with each basic emotion.
After learning the theory, students were asked to fill in the same table based on their personal experience. The table had questions about what caused the emotions they have experienced and how certain emotions have altered their behavior and thinking.
At this stage, students get acquainted with an emotional filter concept. Emotional filtering refers to how we perceive and respond to things using our emotions. Students develop this skill based on personal experience, their own or that of others. Each participant was asked to analyze a conflict situation that happened with another person (e.g., a colleague, friend, family member, student, boss, stranger, etc.) and ended unsatisfactorily. They were asked to describe the emotional filters, thoughts and actions of the interlocutor, as well as the instant and long-term outcomes of the given communication event. The practical task ends with modeling the ideal outcome of the conflict and showing how participants in the conflict should change their emotional filter.
Block IV seeks to develop the ability to evoke certain emotions within self and in others. For this, a list four emotions (adjectives) is proposed. Leading questions help a person immerse himself or herself in a situation where they experienced the described emotion. Students were instructed to recall what brought them to this state, describe their feelings, sounds and visual images present at the time, and the situation itself with all the details.
The closing task of the program sought to teach how to manage the emotional state of the interlocutor. For this, the instructor uses a real-life conflict situation exploited in the previous block.
Participants were asked to think about how to treat the other person in order to alter his emotional state and end the interaction with a favorable outcome.
After training, all subjects underwent a second emotional intelligence test to identify the difference. Two months after the second survey, participants were asked to answer a few additional questions. This interview aimed to check whether the emotional competence enhancement influenced the educational process, discipline and academic performance of students, as well as their communication with others. The questionnaire had seven questions: (1) How do you feel about the quality of the educational process? Did it change after training? (2) Is there any improvement in the classroom discipline after training? (3) Do you think that participating in the given training program affected your communication with students and colleagues? (4) Did teaching sessions become more interesting after training? (5) Do you understand your emotions better after training? (6) Do you understand students better after training? (7) Were you engaged in any conflict situations after training?
Ethical issues. All participants were familiarized with the essence and the purpose of the study. All subjects gave their agreement to participate in the study and consented to processing their data. Some personal information (such as sex and age) will not to be disclosed here. Anonymity was maintained by assigning a personal identification number to each participant.
Research limitations. This study has several limitations. First, it focuses on just one ethnicity and does not take into account the age of the participants and their previous experience in enhancing emotional intelligence. Second, the sample is limited to universities located in two large cities of Kazakhstan. Other cities, regions and countries were neglected.

Results
Results from the first survey were arranged as Table 1 to evaluate five dimensions of emotional intelligence among students. The columns represent studied aspects of emotional intelligence. The rows represent each individual score on the scale within the set range. The highest score possible on each scale is +18 (6 questions, 3 points each), and the lowest score possible is −18 (6 questions, 3 points each). Each cell indicates the number of students who scored a specific amount of points on that scale.
According to the baseline survey, the participating social pedagogue students generally had an average level of emotional intelligence (scale score, −6 to +4 points). Few students had low (−10 points) and high (+13 points) levels.
The average scores of the given dimensions among participants were as follows: Emotional awareness, 44 points; Managing your emotions, 112 points; Self-motivation, 104 points; Empathy, 156 points; Managing the emotions of other people, 43 points.
Overall, the participating students were most inclined to empathize with the current emotional state of another person and struggled with identifying emotions and noticing when they are present. Even though these results are not critical, the above scores are insufficient for through employed in the social sphere.
Experts believe that social pedagogues must be able to communicate effectively with others (McCarthy et al., 2015). This skill is essential for organizing social pedagogical activity, gaining trust, and maintaining discipline in the classroom. In addition, high emotional intelligence will allow teachers to take a more responsible attitude towards their work, notice any shifts in their emotional background, and adjust it as needed. Teachers who know how to build a trust-based relationship with their students are more likely to spark interest in their subject and encourage students to attend their class and make good progress (Maamari and Majdalani, 2019).
Participation in the Emotional Intelligence Training Program improved the EQ scores of students, as evidenced by the results from the post-training survey ( Table 2). The difference between the pretest and posttest scores is significant.
Here are the average scores of the second test: Emotional awareness, 351 points; Managing your emotions, 253 points; Self-motivation, 348 points; Empathy, 334 points; Managing the emotions of other people, 304 points.
As can be seen, students scored highest on Emotional Awareness and Self-motivation. Managing your Emotions is attributed the worst score. For convenience, below is a comparison chart providing student data before and after the training.

Discussion
The EQ training has proven to yield evident results. All participants within this study showed improvements in their levels of emotional intelligence after exposure to the emotional intelligence training program. Some researchers, however, indicate the presence of sex and age differences in the extent of such improvement between individuals (Cabello et al., 2016). For instance, female teachers tend to score higher on all five EQ measures (Latif et al., 2017;Valente et al., 2020).
According to the interview, emotional intelligence training enhanced the quality of the educational process. Beyond that, students reported having a better understanding of emotional responses and the emotional states, their own and those of other people. Other observations they made include better communication with others and better classroom discipline, which led to better academic performance. This finding coincides with similar studies investigating the relationship between emotional intelligence and teacher performance (Valente et al., 2019(Valente et al., , 2020. Some other interesting outcomes were provided by Ukrainian researchers who analyzed how raising the level of emotional intelligence among teaching methods specialists may further promote their professional growth (by increasing their emotional competence). Considering it as a companion to the current study, it cannot be left unnoticed that the authors adopted the Hall Emotional Intelligence Test as the key diagnostic tool. Their approach to training preschool teaching methods specialists demonstrated significant shifts of the arithmetic mean indicator for raw scores among all the respondents-from 43.87 to 57.54. These results confirmed that the training system they proposed allows developing strategies for modulation of training participants' emotions, acquainting them with emotion expression techniques, and promoting their emotional competence. Likewise, the researchers concluded that the development of emotional intelligence positively affects teaching skills (Sabol et al., 2020).
In like manner, a study conducted among 200 Malaysian student teachers demonstrated a significant impact of the state of emotional intelligence on respondents' stress tolerance. Its findings demonstrated that emotional intelligence, self-efficacy, and subjective well-being affect the perception and response to stressful situations in the educational environment with good predictive accuracy and relevance (Ngui and Lay, 2020).
Overall, the collected results may be helpful in future research on developing the emotional intelligence of teacher students (Berenji and Ghafoori, 2015). Further studies should also focus on improving the EQ training program and adjusting it for those employed in the education sector (Pugazhenthi and Srinivasan, 2018).

Conclusions
The present study aimed to expose social pedagogue students to the EQ training program and track their emotional progress. The results showed a marked improvement from the baseline: the percentage of positive scores increased by 22-32% depending on the competence. All participants said the quality of the educational process has improved. They also reported having better classroom discipline and a better understanding of emotions. These findings may be valuable for further research on emotional intelligence in education. They can be applied in the psychology of labor and pedagogy. In line with this, the methodology and outcomes presented can be taken advantage of for investigating the role of emotional intelligence in educating future teachers as well as for designing similar training programs to develop a better understanding of and control over one's own emotions.
