Introduction The teaching and learning process is influenced by numerous factors that collectively shape student outcomes. Central to this process are the classroom practices and management strategies employed by educators, which are essential for fostering effective teaching and successful student learning. The literature consistently highlights the significance of quality teaching and effective classroom management as prerequisites for achieving educational goals, particularly during the formative years of a teaching career 1. Effective teaching extends beyond content delivery; it is intrinsically linked to a teacher’s ability to create a conducive learning environment characterized by well-organized procedures that foster a positive atmosphere, thus enhancing student 1 Vernon F.

A critical aspect of effective teaching practices involves the application of research-backed models, such as Marzano’s Dimensions of Learning. This model provides a comprehensive framework for fostering cognitive, emotional, and social growth in students. It emphasizes the interaction of five dimensions of learning: positive attitudes toward learning, knowledge acquisition and integration, deepening and refining knowledge, purposeful use of knowledge, and productive habits of mind3. Despite the proven efficacy of this model, there remains a significant gap in its implementation, largely due to insufficient training and understanding among educators 4. In this study, the degree of employment refers to the extent of teachers’ competence and knowledge in applying Marzano’s Dimensions of Learning Model. Hamadna (2007) defines it as “the degree of teachers’ competence and knowledge of the principles of Marzano’s Dimensions of Learning Model, measured by the score that the teacher sets for himself in the tool approved for this purpose”5. Marzano et al. describe the model as “a practical classroom teaching framework consisting of organized and sequential steps that foster interaction between the model’s five thinking dimensions”. These dimensions facilitate the development of positive learning attitudes, the integration of new knowledge, the deepening and refining of knowledge, and the cultivation of productive mental habits. The level of a teacher’s application of Marzano’s Dimensions of Learning Model is defined procedurally as the extent to which the teacher possesses the knowledge and competencies necessary to successfully implement this model in the classroom. This procedural definition is essential for assessing how well teachers are integrating these principles into their teaching practices. A review of prior studies highlights the importance of Marzano’s model in enhancing teaching practices across various educational contexts. For instance, Al-Shuwaili evaluated the performance of Arabic language teachers in Iraq using Marzano’s Learning Dimensions Model. The study revealed that while teachers exhibited strong performance in fostering positive attitudes towards learning, their effectiveness in other dimensions—such as knowledge acquisition and refinement—was notably low, indicating a need for further development in these areas6. Similarly, Youssef investigated the extent to which Arabic language teachers in Jordan 2 Donna Pendergast, Susanne Garvis, and Jayne Keogh, "Pre-Service Student-Teacher Self-Efficacy Beliefs: An Insight into the Making of Teachers," Australian Journal of Teacher Education 36, no. 12 (2011): 46–57.

The findings suggested that although the practice was moderate, female teachers were more likely than their male counterparts to adopt these contemporary strategies. This underscores the influence of gender on teaching practices, a factor also explored in the current study7. Zalami focused on the teaching practices of middle school mathematics teachers in Jordan, finding that while teachers were proficient in integrating new knowledge, their application of other dimensions of Marzano’s model, such as the meaningful use of knowledge, was lacking. This highlights the variability in the application of Marzano’s principles across different educational contexts8. Foreign studies, such as Poulou et al., have further explored the relationship between teachers’ self-efficacy and classroom practices, revealing significant discrepancies between teachers' self-perceptions and their observed instructional behaviors9. Narinesingh examined the impact of Marzano’s evaluation models on student proficiency in the U.S., finding a positive correlation between the application of Marzano’s principles and student growth, particularly in middle school settings10. Marzano’s Dimensions of Learning Model posits that effective learning requires the integration of five key dimensions. The first dimension emphasizes the creation of positive attitudes and perceptions about learning. This involves preparing the classroom environment and connecting new lessons with students' previous experiences 11. The second dimension focuses on the acquisition and integration of knowledge, where students are encouraged to assimilate new information with their existing knowledge base 12. The third dimension involves deepening and refining knowledge, a process that stimulates critical thinking through activities such as comparison, classification, induction, and deduction 13. The fourth dimension emphasizes the purposeful use of knowledge, guiding students to apply their learning in real-life situations through decision-making, problem-solving, and invention 14. 7 Al-Jaafra Abdul Salam Youssef, "The Degree to Which Arabic Language Teachers Practice Modern Trends in Teaching the Arabic Language from Their Point of View," Al-Quds Open University Journal for Educational Research and Studies 4, no. 13 (2016): 255-284. 8 Talal Tael Al Mushaqaba, "The Effect of Using Teaching Strategy Based on Model Dimensions of Learning Marzano Learning and Solving Math Problems to Students in the Basic Stage in Jordan" (PhD diss., Amman Arabic University for Higher Studies, 2008). 9 Maria Poulou, Linda Reddy, and Charles H.

Marzano argues that fostering positive attitudes and productive mental habits can serve as foundational educational goals across all content areas 16. These dimensions not only guide effective learning but also provide a framework for teachers to plan and implement instructional strategies that align with the broader objectives of modern education 17. In conclusion, this study aims to assess the level of application of Marzano’s Dimensions of Learning Model by teachers in Erbil city schools. By evaluating how these principles are integrated into teaching practices, the research seeks to contribute to the ongoing efforts to improve educational outcomes through evidence-based strategies. Method Research Variables This study involved two types of variables: 1. Demographic Variables: These included gender (male, female) and the number of years of experience (less than 10 years, 10 years or more). 2. Dependent Variable: The dependent variable was the level of application of the principles of Marzano's Dimensions of Learning Model by teachers in Erbil city schools in their teaching methods. The research employed a descriptive-analytical method, which is designed to describe and interpret the nature of the phenomenon under investigation. According to Homsi (2003), this method aids in explaining existing educational phenomena and elucidating the relationships between them (p. 86). It allows the researcher to gather comprehensive information based on real- world data, offering not just a collection of facts, but also their description, analysis, measurement, evaluation, and interpretation. Population The research population comprised all middle school teachers working in Erbil city schools, totaling 5,477 teachers, as recorded by the Statistics Office in the Erbil Education Directorate for the academic year 2023-2024. 15 Yusuf Qutami and Omaima Omor, Habits of Mind and Thinking (Amman: Dar Al-Fikr, 2005).

Volume 9, Number 2, August 2024| 71 Sample A simple random sampling method was used to select the research sample from the original population, acknowledging the lack of homogeneity in terms of years of experience. The sample included 328 teachers, representing 6% of the original research population. The distribution of the research sample according to the demographic variables is presented in Table 1. Table 1: Distribution of Research Sample by Demographic Variables Variable Category Number of Individuals Percentage Gender Male 144 43.90% Female 184 56.10% Total 328 100% Experience < 10 years 175 53.35% ≥ 10 years 153 46.65% Total 328 100% Instrument To assess the level of teachers' application of Marzano’s Dimensions of Learning Model, a questionnaire was developed. The questionnaire was designed based on a review of relevant studies, including those by Al-Shuwaili (2016), Youssef (2016), Hazaima (2019), and Zalami (2020). It comprised 50 items distributed across five dimensions: forming positive attitudes toward learning, acquisition and integration of knowledge, expanding and refining knowledge, purposeful use of knowledge, and productive habits of mind. The item distribution is detailed in Table 2. Table 2: Distribution of Questionnaire Items by Research Dimensions Dimension Number of Items Item Numbers Forming positive attitudes toward learning 10 1-10 Acquisition and integration of knowledge 10 11-20 Expanding and refining knowledge 10 21-30 Purposeful use of knowledge 10 31-40 Productive habits of mind 10 41-50 Questionnaire Administration Participants responded to the questionnaire using a five-point Likert scale, where responses ranged from "Very High" to "Very Low." The scores were assigned as follows: 5 for "Very High," 4 for "High," 3 for "Medium," 2 for "Low," and 1 for "Very Low." Pilot Study A pilot study was conducted to ensure the clarity and comprehensibility of the questionnaire items and instructions. The questionnaire was administered to a small sample of 28 teachers in Erbil who were not part of the main research sample. Based on the pilot study, no changes were deemed necessary, as the items were found to be clear and understandable. Validity of the Questionnaire Face Validity: The questionnaire's face validity was confirmed through expert review. Five faculty members from the College of Education evaluated each item for relevance and clarity. Volume 9, Number 2, August 2024| 72 Based on their feedback, some items were revised for improved wording and clarity. The final questionnaire consisted of 50 items. Construct Validity: The construct validity of the questionnaire was assessed through Pearson correlation coefficients, which measured the relationship between the total score and the sub- dimensions. As shown in Table 3, the correlation coefficients ranged from 0.846 to 0.916, indicating a strong and statistically significant correlation, thus confirming the questionnaire’s accuracy in measuring its intended purpose. Table 3: Pearson Correlation Coefficients Between Total Score and Sub-Dimensions Dimension Pearson Correlation Coefficient Forming positive attitudes toward learning 0.869** Acquisition and integration of knowledge 0.846** Expanding and refining knowledge 0.916** Purposeful use of knowledge 0.905** Productive habits of mind 0.853** Reliability of the Questionnaire The reliability of the questionnaire was evaluated using three methods: test-retest reliability, split-half reliability, and Cronbach’s alpha. The results, shown in Table 4, indicate a high degree of reliability across all dimensions. The overall reliability was 0.959 for test-retest, 0.947 for split-half, and 0.874 for Cronbach’s alpha, suggesting that the questionnaire is highly reliable for measuring the application of Marzano’s Dimensions of Learning Model.

Research Results and Discussion Research Question 1: What is the Level of Application of the Principles of Marzano’s Dimensions of Learning Model by Teachers in Erbil City Schools in Their Teaching Methods? To address this question, the arithmetic mean, standard deviation, and rank average were calculated for the responses to the questionnaire items, which assessed the level of application of Marzano’s Dimensions of Learning Model by teachers in Erbil city schools. The analysis utilized a rating scale where scores were divided into five levels: very low (1.00–1.80), low (1.81–2.60), Volume 9, Number 2, August 2024| 73 medium (2.61–3.40), high (3.41–4.20), and very high (4.21–5.00). The results are summarized in Table 6. Table 6: Arithmetic Means, Standard Deviations, and Rank Averages for the Application of Marzano’s Dimensions of Learning Model by Teachers in Erbil City Schools Dimension Arithmetic Mean Standard Deviation Rank Average Rank Level of Application Forming positive attitudes toward learning 21.65 7.880 2.16 5 Low Acquisition and integration of knowledge 22.56 8.392 2.25 4 Low Expanding and refining knowledge 23.02 8.683 2.30 2 Low Purposeful use of knowledge 23.19 8.446 2.31 1 Low Productive habits of mind 22.74 8.435 2.27 3 Low Total Score 113.16 39.744 2.26 - Low As shown in Table 6, the overall level of application of Marzano’s Dimensions of Learning Model by teachers in Erbil city schools is rated as low, with a total rank average of 2.26. The highest-ranked dimension is "Purposeful use of knowledge" (M = 23.19, SD = 8.446, Rank = 1), while the lowest-ranked dimension is "Forming positive attitudes toward learning" (M = 21.65, SD = 7.880, Rank = 5). These results indicate significant deficiencies in the teachers' performance, particularly in areas critical to fostering cognitive and conceptual understanding in students. Research Question 2: Are There Statistically Significant Differences Between the Average Scores of the Research Sample’s Responses to the Questionnaire Based on Gender? To examine potential differences in application levels based on gender, a t-test was conducted comparing the mean scores of male and female teachers. The results are detailed in Table 8. Table 8: T-Test Results for Differences in Application of Marzano’s Dimensions Based on Gender Dimension Gender N Mean SD df T- value P- value Significance Forming positive attitudes toward learning Male 144 15.84 6.504 326 5.885 0.000 Significant Female 184 22.08 8.020 Acquisition and integration of knowledge Male 144 17.55 7.593 326 6.279 0.000 Significant Female 184 22.97 8.541 Expanding and refining knowledge Male 144 18.37 7.940 326 6.090 0.000 Significant Female 184 23.51 8.810 Purposeful use of knowledge Male 144 18.58 7.597 326 6.003 0.000 Significant Female 184 23.58 8.560 Productive habits of mind Male 144 18.32 7.382 326 6.080 0.000 Significant Volume 9, Number 2, August 2024| 74 Female 184 23.19 8.564 Total Score Male 144 88.66 34.260 326 6.237 0.000 Significant Female 184 115.34 40.324 The t-test results in Table 8 reveal statistically significant differences between male and female teachers in the application of Marzano’s Dimensions of Learning Model across all dimensions, with female teachers consistently scoring higher. The overall t-value of 6.237 and a p-value of 0.000 indicate a significant difference at the 0.05 level, favoring female teachers. This suggests that female teachers are more likely to implement effective teaching practices aligned with Marzano’s model, possibly due to a higher motivation to succeed and a greater emphasis on facilitating dialogue, enhancing student expression, and fostering critical thinking. Research Question 3: Are There Statistically Significant Differences Between the Average Scores of the Research Sample’s Responses Based on Years of Experience? To explore differences based on years of teaching experience, a t-test was conducted comparing teachers with less than 10 years of experience to those with 10 years or more. The results are presented in Table 9. Table 9: T-Test Results for Differences in Application of Marzano’s Dimensions Based on Years of Experience Dimension Experience N Mean SD df T- value P- value Significance Forming positive attitudes toward learning < 10 years 175 18.58 5.248 326 8.767 0.000 Significant ≥ 10 years 153 26.84 8.447 Acquisition and integration of knowledge < 10 years 175 19.69 5.713 326 7.777 0.000 Significant ≥ 10 years 153 27.81 9.498 Expanding and refining knowledge < 10 years 175 20.17 6.046 326 7.552 0.000 Significant ≥ 10 years 153 28.40 9.812 Purposeful use of knowledge < 10 years 175 20.88 6.195 326 6.111 0.000 Significant ≥ 10 years 153 27.60 9.777 Productive habits of mind < 10 years 175 20.29 5.711 326 6.682 0.000 Significant ≥ 10 years 153 27.49 9.991 Total Score < 10 years 175 99.61 25.723 326 7.858 0.000 Significant ≥ 10 years 153 122.14 37.085 The data in Table 9 indicate statistically significant differences in the application of Marzano’s Dimensions of Learning Model based on years of teaching experience. Teachers with 10 years or more of experience scored significantly higher across all dimensions, with a total t-value of 7.858 and a p-value of 0.000. This suggests that more experienced teachers are better at applying Marzano’s principles in their teaching methods, likely due to greater familiarity with the model and accumulated teaching experience. Volume 9, Number 2, August 2024| 75 Discussion The findings from this study provide a deeper understanding of the application of Marzano’s Dimensions of Learning Model by teachers in Erbil city schools, highlighting significant differences based on years of teaching experience. The analysis demonstrated that teachers with 10 years or more of experience applied the principles of Marzano’s model more effectively than those with less experience. This outcome is statistically significant, as indicated by the t-value of 7.858 and a p-value of 0.000, confirming that experience plays a critical role in the effective implementation of educational frameworks. The superior performance of more experienced teachers can be attributed to several key factors: 1. Enhanced Professional Development: Teachers with greater experience are likely to have participated in more extensive professional development opportunities. In the context of Erbil, the Directorate of Education frequently offers training programs focused on contemporary teaching strategies, including those based on Marzano’s Dimensions of Learning. These programs are designed to enhance teaching competencies by introducing educators to advanced instructional techniques, classroom management strategies, and student assessment methods. As teachers accumulate years of experience, they have more opportunities to attend such training, refine their skills, and integrate these strategies into their daily teaching practices. 2. Cumulative Experience and Mastery: Over time, experienced teachers develop a nuanced understanding of classroom dynamics, student needs, and effective teaching methodologies. This cumulative experience allows them to master the application of complex models like Marzano’s, particularly in adapting these principles to diverse classroom settings. Their ability to organize the learning environment, select tasks that foster critical thinking, and facilitate meaningful student interactions reflects a depth of pedagogical expertise that is typically acquired over years of practice. 3. Application of Marzano’s Principles: The study’s findings suggest that experienced teachers are more adept at applying specific dimensions of Marzano’s model, such as purposeful use of knowledge, expanding and refining knowledge, and fostering productive habits of mind. These dimensions are crucial for developing students’ cognitive and metacognitive skills. Experienced teachers’ familiarity with these principles enables them to create more effective learning experiences, where students are encouraged to engage in higher-order thinking, problem-solving, and reflective learning. This contrasts with less experienced teachers, who may struggle with the practical application of these principles due to limited exposure and practice. 4. Self-Efficacy and Confidence: The link between teaching experience and self-efficacy is well-documented in educational research. Poulou et al. emphasize that teachers with higher self-efficacy are more likely to implement effective classroom practices, which directly correlates with their ability to apply Marzano’s model. Experienced teachers, having encountered a variety of teaching challenges and successes, tend to exhibit greater confidence in their instructional abilities. This confidence translates into more effective Volume 9, Number 2, August 2024| 76 classroom management, more innovative instructional strategies, and a stronger focus on student-centered learning, all of which are integral to Marzano’s framework18. The results of this study align with findings from previous research, which similarly emphasize the importance of experience in the application of educational models. Al-Shuwaili’s 19 study on Arabic language teachers in Iraq revealed that more experienced teachers were better at fostering positive learning attitudes and integrating new knowledge, which are key components of Marzano’s model. This suggests that experience not only enhances a teacher’s ability to implement specific dimensions of the model but also improves their overall instructional effectiveness. Moreover, Zalami 20 found that experienced mathematics teachers in Jordan demonstrated higher proficiency in applying Marzano’s dimensions, particularly in integrating knowledge and fostering meaningful use of that knowledge. The current study’s findings corroborate this, indicating that the depth of understanding and skill required to implement these dimensions effectively is often a product of extensive teaching experience. In addition, the present study’s findings extend the research of Poulou et al) by reinforcing the connection between self-efficacy and the successful application of Marzano’s principles. The experienced teachers’ ability to implement these principles more effectively can be seen as both a cause and a consequence of higher self-efficacy, which is built through years of practice and professional development. The significant difference in application levels between more and less experienced teachers highlights a critical area for intervention. To bridge this gap, it is imperative that less experienced teachers receive targeted support and professional development tailored to Marzano’s Dimensions of Learning Model. Such training should not only focus on the theoretical aspects of the model but also provide practical, hands-on experiences that allow teachers to apply these principles in real classroom settings. Furthermore, educational policymakers in Erbil and similar contexts should consider implementing mentorship programs where less experienced teachers can learn from their more seasoned colleagues. These programs could facilitate the transfer of knowledge and skills, ensuring that all teachers, regardless of experience, are equipped to apply Marzano’s principles effectively. While this study provides valuable insights, it is important to acknowledge its limitations. The study was conducted within a specific geographic and cultural context, which may limit the generalizability of the findings. Future research could explore the application of Marzano’s model across different regions and educational systems to determine whether similar patterns emerge. Additionally, longitudinal studies could examine how teachers’ application of Marzano’s principles evolves over time, providing a more dynamic understanding of the relationship between 18 Maria Poulou, Linda Reddy, and Charles H. Dudek, "Relation of Teacher Self-Efficacy and Classroom Practices: A Preliminary Investigation," School Psychology International 40, no. 1 (2019): 25–48. 19 Haider Mohsen Salman Al-Shuwaili, "Evaluating the Performance of Arabic Language Teachers in Light of Marzano’s Learning Dimensions Model," Dhi Qar University Journal 11, no. 2 (2016): 134-162. 20 A.

Volume 9, Number 2, August 2024| 77 experience and teaching effectiveness. This study confirms that teaching experience significantly enhances the ability to apply Marzano’s Dimensions of Learning Model effectively. The findings underscore the importance of continued professional development and support for less experienced teachers, as well as the value of experience in fostering high-quality educational practices. By addressing the identified gaps, educators and policymakers can work towards ensuring that all teachers are capable of delivering the best possible education to their students, fully utilizing the potential of Marzano’s model to improve learning outcomes. Conclusion The findings of this study indicate that the overall level of application of Marzano’s Dimensions of Learning Model by teachers in Erbil city schools is low, with an arithmetic mean score of 2.26. This suggests that the principles of Marzano’s model are not being fully implemented in teaching practices across these schools. Additionally, the study reveals significant differences in application levels based on gender and years of experience. Female teachers demonstrated a higher level of application compared to their male counterparts, and teachers with 10 or more years of experience showed greater proficiency in applying Marzano’s principles than those with less experience. Based on these findings, it is crucial to enhance teacher training programs, particularly by focusing on teaching practices that reflect the principles of Marzano’s Dimensions of Learning Model, with special attention to areas identified as weak in this study. Increasing teachers' awareness and skills related to the Marzano model is also essential, which could be achieved through targeted training courses, workshops, model lessons, scientific meetings, and peer visits. Furthermore, incorporating modern teaching trends into instructional practices, particularly those aligned with Marzano’s model, is recommended. This includes using various activities, cooperative exercises, concept maps, and higher-order thinking questions in textbooks and classroom activities. Providing the necessary resources and support for the implementation of these modern teaching strategies in the classroom is also vital. Lastly, further research should explore the application of Marzano’s Dimensions of Learning Model at different educational levels, such as the preparatory stage, and evaluate the effectiveness of training programs designed to enhance teachers’ performance in light of Marzano’s principles. These steps are intended to improve the overall application of Marzano’s model in teaching practices, thereby contributing to the enhancement of educational quality in Erbil city schools.
