Since 1995 when the psychologist Goleman brought the concept of emotional intelligence to the world, hundreds of scholars have been conducting research around the world about the characteristics of emotional intelligence and its impact (
Gómez-Leal et al. 2021). In the educational field, most of the conducted research has focused on the emotional intelligence of the schools’ leaders, but rarely found a study that investigates the emotional intelligence skills and competencies of teachers, and then explores the impact on students’ academic achievement (
Abiodullah and Aslam 2020). To that extent, this study focuses on exploring the emotional intelligence skills and competencies that most teachers have, and at the same time investigating the impact on students’ academic achievement. Teachers need to improve their emotional intelligence because caring and compassion are essential characteristics that every teacher should have (
Roe 2020).
This research aims to study the level of emotional intelligence of teachers and explore the impact of the level of a teacher’s emotional intelligence on their students’ academic achievement. More specifically, regarding the objectives of the study, the following hypotheses were formed before the study: Some teachers need to improve their emotional intelligence skills and competencies; teachers with high emotional intelligence traits are more capable of leading and influencing their students toward learning; and teachers who have high-level emotional intelligence have a more positive effect on their students’ academic performance.
1.1. Conceptual Framework
Emotional intelligence is a complicated concept that encompasses a variety of cognitive, emotional, and interpersonal skills (
Mancini et al. 2022). People with high levels of EI are better able to control their emotions, comprehend others’ emotions, and use emotional information to guide their thinking and behavior, which improves the quality of their interpersonal interactions both personally and professionally (
Moors et al. 2013). To delve deeper in the most common theories related to emotional intelligence (EI) characteristics, Peter Salovey and John Mayer developed Mayer and Salovey’s Four Branch Model, which proposes that EI consists of four interrelated branches: perceiving emotions, using emotions, understanding emotions, and managing emotions. According to this model, individuals who possess high EI are able to accurately perceive, use, understand, and manage their own emotions, as well as the emotions of others (
Olderbak et al. 2019). The second model, Goleman’s Mixed Model, developed by Daniel Goleman, proposed a mixed model of EI that includes five elements: self-awareness, self-regulation, motivation, empathy, and social skills. According to Goleman, these elements are interrelated and work together to determine an individual’s overall EI (
Sfetcu 2020).
The third model, the Bar-On Emotional Quotient Inventory (EQ-i), developed by Reuven, measures EI using five dimensions: self-perception, self-expression, interpersonal, decision-making, and stress management. The Bar-On model proposes that EI is composed of a range of skills and abilities that can be developed through training and practice (
Bar-On 2003;
Jacquelin 2017;
Montgomery et al. 2010). While the fourth model “Trait EI Theory” proposes a concept of EI as a set of personality traits that are distinct from traditional measures of intelligence (
Petrides et al. 2016). Trait EI includes a range of characteristics, such as self-confidence, emotional self-awareness, adaptability, and social competence. According to this theory, individuals who possess high trait EI are better able to manage their own emotions and those of others and are more likely to be successful in both personal and professional relationships (
Petrides 2010). Also, the emotional-cognitive theory, which was proposed by Joseph Forgas (
Williams et al. 2013), suggests that emotions play an important role in cognitive processes, such as memory, judgment, and decision-making. According to this theory, individuals who are able to effectively manage their emotions are better able to use emotional information to inform their cognitive processes, leading to better decision-making and problem-solving abilities (
Oatley and Johnson-Laird 2014).
To conduct this research, the emotional-cognitive theory (ECT) was considered as it provides a comprehensive framework for understanding how emotions and cognition interact to shape behavior, including in educational settings. ECT suggests that emotional processes play a critical role in learning and decision-making, and that emotional intelligence can be developed through practice and training (
Oatley and Johnson-Laird 1987). According to (
Johnson 2008) emotional-cognitive theory (ECT) proposes that emotions play an important role in cognitive processes, such as memory, judgment, and decision-making. According to this theory, emotions can influence how we process and remember information, as well as how we make decisions and judgments. Using ECT as the theoretical framework for the proposed research has several advantages. First, it provides a clear conceptual basis for investigating the relationship between teachers’ emotional intelligence, teaching practices, and students’ outcomes. By using ECT to guide the research, the study can explore how teachers’ emotional intelligence affects their teaching practices, and how these practices in turn influence students’ outcomes (
Paloş et al. 2011). Second, a considerable body of evidence supports ECT and contends that emotional intelligence is a major predictor of grades, test scores, and classroom behavior, among other aspects of academic success (
Karkada et al. 2020;
Parker et al. 2004;
Suleman et al. 2019). The proposed study can add to the body of research supporting the significance of emotional intelligence in educational contexts, particularly in connection to the effectiveness of instruction (
Johnson 2008). Third, ECT highlights the value of emotional self-awareness and emotion management, which are essential elements of emotional intelligence. The proposed study can advance our knowledge of how emotional self-awareness and regulation can be promoted in educational settings by looking at the impact of emotional intelligence on teaching methods and student results (
Reisenzein 2018). Overall, employing ECT as the theoretical framework for the proposed research can contribute to the provision of a thorough and fact-based understanding of the relationship between teachers’ emotional intelligence, and student outcomes (
Shafait and Huang 2022) and can offer helpful insights for enhancing educational practices and outcomes.
According to (
Cerda et al. 2015;
Yi et al. 2021) several variables are included in the emotional-cognitive theory: first, the emotional state, which can be defined as a state of an individual that can influence their cognitive processes, such as memory and decision-making (
LeBlanc et al. 2015). For example, research has shown that individuals in a positive emotional state are more likely to remember positive information and make more optimistic judgments (
Talarico et al. 2009), while those in a negative emotional state are more likely to remember negative information and make more pessimistic judgments (
Talarico et al. 2009;
Rusting and DeHart 2000).
Second, emotional regulation refers to an individual’s ability to manage their emotions effectively (
Thompson 1994;
Hoffmann et al. 2020). Individuals who are better able to regulate their emotions are more likely to use emotional information to inform their cognitive processes positively, leading to better decision-making and problem-solving abilities. Third, attention, as it plays a critical role in cognitive processes, and emotions can influence what we pay attention to (
Li et al. 2020). For example, emotions can influence our selective attention, or the ability to focus on one stimulus while ignoring others (
Schindler and Straube 2020). Emotions can also influence our divided attention, or the ability to attend to multiple stimuli simultaneously (
Lieskovská et al. 2021). Fourth is memory, where emotions can also influence how we process and remember information (
Kensinger and Ford 2020). For example, emotional events are often remembered more vividly than neutral events, and emotions can influence the type of information that is encoded into memory (
Congleton and Berntsen 2020). Judgment and decision-making are also considered, as emotions can also influence how we make judgments and decisions (
Van Kleef and Côté 2022). For example, emotions can influence our risk-perception and our willingness to take risks, as well as our trust in others and our willingness to co-operate with others (
Oh et al. 2021). Overall, ECT proposes that emotions are a critical variable in cognitive processes, and that understanding how emotions influence these processes can lead to better decision-making and problem-solving abilities.
In summary, EI has evolved over time, with early models focusing on cognitive abilities related to emotions (
Sternberg 2000). Daniel Goleman’s influential framework, utilized in this study, broadened the definition to encompass a wider range of competencies. These include self-awareness, emotional regulation, self-motivation, empathy, and social skills. This research delves into these specific aspects of EI through a researcher-designed questionnaire and explores how they influence teachers’ ability to create positive learning environments and student academic achievement. In other words, this study focuses on how specific aspects of emotional intelligence, such as self-awareness and empathy, influence teachers’ impact on student achievement, rather than just general leadership qualities.
1.2. Literature Review
Emotional intelligence (EI) has a potential impact on a range of teaching and learning domains, and it has attracted a lot of attention in the field of educational research (
Yin et al. 2013). Using the results of recent studies as well as theoretical frameworks put forth by experts in the field, this literature review examines the literature on the relationship between teachers’ emotional intelligence and students’ academic achievement. A study by
Mohzan et al. (
2013) examines the relationship between students’ academic achievement and emotional intelligence at the Universiti Teknologi Mara (UiTM) Education Faculty. A questionnaire that asks about students’ academic performance and emotional intelligence level was used to collect the data for this study. The study’s findings indicate that the participants (who were pre-service teachers) possess a high degree of emotional intelligence. It has been discovered that there is a strong and positive correlation between the respondents’ academic achievement and the two categories of emotional intelligence examined, “self-assessment and understanding of emotions.” The study’s conclusions have significant ramifications for understanding the importance of emotional intelligence and how it relates to students’ academic achievement, particularly for pre-service teachers. This result is aligned with
Cherniss et al. (
2006) which proves that there is now much more empirical support for EI theory.
A study conducted by
Olimat (
2016) aimed to examine the association between achievement and quality of life among Al Yarmouk University students and emotional intelligence. Three hundred students who enrolled at the university in the first semester of the academic year 2014/2015 made up the study’s sample. The study employed the Daniel Golman quality of life and emotional intelligence questionnaire, with modifications made to the emotional intelligence items to account for Jordan’s context. The study’s findings demonstrated a statistically significant relationship between academic achievement and emotional intelligence, as well as between academic achievement and quality of life.
In the framework of the teaching–learning process, the
Sekreter (
2019) study was conducted by reviewing literature to investigate the function of emotional intelligence (EI) in teacher effectiveness and organizational productivity. It emphasizes the use of emotional intelligence (EI) abilities in effective teaching and how they may be used to create learning environments that are conducive to learning and improve student results. While a number of criteria, including professionalism, subject matter competence, and classroom management abilities play a role in teacher effectiveness, emotional intelligence (EI) stands out as a critical differentiator for the most successful educators. Establishing positive teacher–student connections and putting effective emotional learning programs into action require an understanding of students’ emotional states and behaviors. The study leads to the conclusion that teachers’ ability to support children’s good developmental outcomes and academic success is highly influenced by their emotional competence.
Several research studies provide further support for the notion that teachers’ emotional intelligence correlates with students’ academic achievement. For instance,
Wahyuni et al. (
2021) conducted quantitative research with a correlational approach determining the level of emotional intelligence and the level of student achievement, as well as to determine whether there is a significant relationship between emotional intelligence and student achievement in social studies subject class IX at SMP Negeri 10 Samarinda during the academic year 2021/2022, as well as the level of emotional intelligence and student achievement. A probability selection strategy using proportional random was employed in this study to select 78 individuals from a sample of 326 students in class IX of SMP Negeri 10 Samarinda. The author used the emotional intelligence scale, which refers to the five components of emotional intelligence and documentation of student report cards, in an attempt to gather data. Based on the results of the study, it showed that there was a significant relationship between emotional intelligence and student achievement in class IX of SMP Negeri 10 Samarinda.
In conclusion, the correlation between teachers’ emotional intelligence and students’ academic achievement is a topic of increasing interest in educational research. Drawing on theoretical frameworks such as Daniel Goleman’s model of emotional intelligence and empirical evidence from recent studies, this literature review highlights the importance of emotional intelligence in shaping teaching practices and student outcomes (
Krishnan and Awang 2020;
Modupe and Ositoye 2010). Moving forward, further research is needed to explore the mechanisms through which teachers’ emotional intelligence influences academic achievement and to develop effective interventions for enhancing emotional intelligence among educators. In nutshell, this quantitative research study that aims to examine the relationship between teachers’ emotional intelligence and its impact on students’ achievement will be as follows:
Independent variable: Teachers’ emotional intelligence level or readiness. This variable will be operationalized using a standardized measure of emotional intelligence, such as the Emotional Intelligence Appraisal (EIA) developed by Travis Bradberry and Jean Greaves (
Barackett et al. 2011).
Dependent variable: Students’ learning outcomes. This variable will be operationalized using standardized measures of academic achievement, such as scores on standardized tests or grades in the subject area taught by the teacher. The process of analyzing and discussing the students’ attainment will be performed by focusing on the growth in academic achievement (
Brown and Dutton 2015).
Potential covariates: Other variables that may impact the relationship between teachers’ emotional intelligence and students’ outcomes. For example, demographic characteristics of teachers and students, years of teaching experience, and classroom size (
Jennings and Greenberg 2009).
Null hypothesis (H0): There is no significant relationship between teachers’ emotional intelligence level and students’ attainment. Alternative hypothesis (Ha): There is a significant relationship between teachers’ emotional intelligence level and students’ academic attainment. The additional hypotheses are as follows: Null hypothesis (H0): There is no significant difference in students’ achievement based on their teachers’ level of emotional intelligence, and the Alternative hypothesis (Ha): Students’ achievement is significantly different based on their teachers’ level of emotional intelligence.
