REVIEW OF RELATED LITERATURE
DIFFICULT TEACHING TOPIC
Integrated Science is a pivotal subject in Nigeria’s Junior Secondary School (JSS) curriculum, designed to provide students with a cohesive understanding of scientific principles across various disciplines. However, educators often encounter challenges when teaching specific topics, which can impede student comprehension and interest. Identifying these difficult topics and understanding the underlying reasons is essential for enhancing the effectiveness of science education.
Studies have highlighted several topics within the Integrated Science curriculum that pose significant challenges for both teachers and students:
Reproduction in Plants and Animals: This topic involves complex biological processes that students often find abstract and challenging to grasp. The lack of visual aids and practical demonstrations further complicates understanding.
Cell Structure and Functions: Understanding the microscopic world of cells requires sophisticated laboratory equipment, which many schools lack, making it difficult to convey these concepts effectively.
Newton’s Laws of Motion and Friction: These fundamental physics concepts require practical demonstrations to illustrate principles like inertia, acceleration, and action-reaction forces. The absence of appropriate apparatus hinders experiential learning.
Chemical Reactions and Equations: Balancing chemical equations and understanding reaction mechanisms are areas where students frequently struggle, often due to insufficient laboratory practice and exposure.
Energy Transformation: Concepts such as energy conversion and conservation are abstract and require practical examples, which are often unavailable due to resource constraints.
Several factors contribute to the challenges faced in teaching these topics:
Inadequate Laboratory Facilities: A study by Dorsah et al. (2024) revealed that the absence of laboratories (Mean = 1.0, SD = 0.00) and necessary apparatus (Mean = 1.85, SD = 0.95) significantly hampers the effective teaching of Integrated Science.
Shortage of Instructional Materials: The lack of teaching aids such as charts, models, and multimedia resources limits teachers’ ability to illustrate complex concepts, leading to reliance on rote learning methods.
Large Class Sizes: Overcrowded classrooms make it challenging to conduct interactive and practical sessions, which are crucial for subjects like Integrated Science. This situation often results in a predominantly lecture-based approach, reducing student engagement.
Insufficient Teacher Training: Many educators lack specialized training in Integrated Science, affecting their confidence and competence in delivering complex topics. Continuous professional development opportunities are often limited.
The difficulties in teaching these topics have a direct impact on student outcomes:
Reduced Comprehension: Students struggle to understand abstract concepts without practical demonstrations, leading to superficial learning.
Decreased Interest: Persistent challenges and lack of engagement can diminish students’ interest in science, potentially affecting their future academic choices.
Poor Performance: The combination of the above factors often results in lower achievement levels in assessments related to these challenging topics.
Enhancing Laboratory Infrastructure: Investing in well-equipped laboratories will provide students with hands-on experience, crucial for understanding complex scientific concepts.

SUMMARY, CONCLUSIONS, AND RECOMMENDATIONS
Introduction
This chapter presents a summary of the key findings from the study, conclusions drawn from the results, and recommendations for addressing the challenges identified in teaching difficult topics in Integrated Science in Junior Secondary Schools in Enugu Urban Area, Enugu State. The recommendations aim to provide actionable strategies for improving teaching practices and learning outcomes in Integrated Science.
Summary of the Study
The purpose of this study was to identify the difficult teaching topics in Integrated Science in Junior Secondary Schools (JSS) in Enugu Urban Area and to understand the reasons teachers find these topics challenging. A survey was conducted among 100 Integrated Science teachers selected from 20 secondary schools (both public and private). The study focused on two main research questions:
What topics do teachers find difficult in teaching J.S.S Integrated Science?
Why do teachers have difficulty in teaching these identified topics in Integrated Science?
The study utilized a descriptive survey research design, and the data were collected using a structured questionnaire that included both closed-ended and open-ended questions. Descriptive statistics (mean scores, frequency distribution) were used to analyze the quantitative data, while thematic analysis was applied to the qualitative data.
Summary of Findings
The key findings from the study are as follows:
Identification of Difficult Topics: The study revealed that teachers found the following topics to be the most difficult to teach:
Ecological Systems (mean score = 3.15)
Chemical Reactions (mean score = 3.00)
Structure of Atoms (mean score = 3.00)
Laws of Motion (mean score = 2.90)
Energy Transformations (mean score = 2.75)
Photosynthesis (mean score = 2.95)
Topics such as Ecological Systems and Chemical Reactions had the highest mean scores, indicating they were the most challenging to teach.
Reasons for Difficulty in Teaching: The study also identified several reasons why teachers found these topics difficult:
Lack of Adequate Instructional Materials (60%): Teachers reported difficulties due to the unavailability of resources such as textbooks, laboratory equipment, and visual aids, which hindered their ability to explain complex concepts.
Insufficient Subject Knowledge (45%): Teachers with limited training or less familiarity with the topics (e.g., atomic structure and ecological systems) struggled to deliver the content effectively.
Inadequate Student Engagement (40%): Some topics, such as ecological systems and photosynthesis, were perceived as difficult to teach because students had difficulty engaging with or relating to the material.
Time Constraints (30%): Teachers indicated that the limited time available to cover the curriculum made it challenging to adequately teach difficult topics.
Complexity of the Topics (20%): Teachers acknowledged that certain topics, especially those with abstract concepts, were inherently difficult to teach.
Demographic Influence: The study also revealed that teachers’ years of experience and qualifications had an impact on how difficult they perceived certain topics to be. Teachers with higher qualifications and more years of teaching experience reported fewer difficulties in teaching challenging topics, although they still faced certain challenges related to resource availability and student engagement.
Conclusions
Based on the findings of this study, the following conclusions can be drawn:
Topics that involve complex, abstract, or conceptual content, such as Ecological Systems, Chemical Reactions, and Structure of Atoms, are perceived as the most difficult by Integrated Science teachers in Junior Secondary Schools in Enugu Urban Area. These topics require a higher level of subject knowledge and instructional support, which many teachers currently lack. The availability of instructional materials is a major challenge. Teachers often lack the necessary resources to make the teaching of difficult topics more engaging and understandable for students. This limitation hampers their ability to effectively deliver lessons on topics that require practical demonstrations, such as chemical reactions or ecological systems. Many teachers, particularly those with fewer years of experience or lower qualifications, struggle to teach certain topics due to gaps in their subject knowledge. Continuous professional development and specialized training in Integrated Science are essential for improving teacher competence. Inadequate student engagement is another significant challenge. Many students find topics like Ecological Systems and Photosynthesis difficult to relate to, which results in poor understanding and a lack of interest. Teachers struggle to make these topics more interesting and relevant to students without proper resources or teaching strategies.
Recommendations
Based on the conclusions drawn from the study, the following recommendations are made to improve the teaching of difficult topics in Integrated Science in Junior Secondary Schools:
The government and school management should prioritize the provision of necessary teaching aids, such as laboratory equipment, visual aids, and textbooks, to enable teachers to teach complex topics effectively. Schools should invest in hands-on materials that can help students better understand abstract concepts.
Teachers should be encouraged to use locally available resources, such as plants or simple chemical apparatus, to demonstrate scientific concepts in practical ways.
Continuous professional development programs should be organized to improve teachers’ subject knowledge and teaching skills, particularly in difficult areas such as Ecology, Chemical Reactions, and Atomic Structure.
Teachers with fewer years of experience should be given opportunities to participate in workshops, seminars, and conferences that focus on teaching strategies for abstract topics in Integrated Science.
Teachers should adopt more interactive and student-centered teaching methods, such as inquiry-based learning, group activities, and field trips, to make difficult topics more engaging and relatable to students.
Schools should incorporate real-life examples and practical demonstrations in the teaching of abstract topics to help students connect theoretical knowledge with everyday life.
