Introduction
1.1 Background of the Study
The concept of learning has long been regarded as a multidimensional process, characterized by sensory engagement, cognitive stimulation, and experiential integration. In contemporary educational theory, learning is no longer perceived as a mere transfer of information from teacher to student, but as a transformative experience that occurs through active interaction with one’s environment (Ngugi & Kihoro, 2021). For example, when a child learns to identify various plant species not by reading about them, but by visiting a botanical garden, touching the leaves, and observing differences, the experience is richer and more memorable. This idea of experiential learning underscores the importance of meaningful connections in the process of knowledge acquisition. Such approaches are deeply aligned with subjects that deal with the natural world—one of the most prominent being biology.
Biology, as a core science subject in secondary education, serves as a gateway for students to explore the complexity and diversity of living organisms and life processes. It is an integral subject that not only lays the groundwork for scientific literacy but also fosters critical thinking, analytical reasoning, and problem-solving skills among learners (Oduro & Bekoe, 2022). The teaching of biology in secondary schools is particularly significant because it serves as a foundation for advanced studies in medical, environmental, and agricultural sciences. However, the way biology is taught greatly influences student interest and achievement in the subject. Teachers are therefore expected to employ pedagogical strategies that bridge the gap between abstract content and students’ real-world experiences (Ekon & Uzodimma, 2023). The abstract nature of many biological concepts, such as cellular respiration or ecological balance, necessitates innovative teaching approaches that go beyond textbook instruction and verbal explanation.
This is where visual instructional materials come into the picture, offering an enriched teaching-learning experience by simplifying complex biological content. Visual instructional materials such as charts, models, diagrams, videos, and animations play a crucial role in enhancing comprehension and retention, especially in science subjects where visualization supports cognitive processing (Isong & Ukoha, 2021). The use of these materials in secondary school biology classes helps make abstract topics concrete, supports inclusive learning by catering to visual learners, and increases student engagement (Tambe & Olarewaju, 2020). By transforming theoretical lessons into visual narratives, these materials allow learners to better grasp the structure of a cell, the process of mitosis, or the flow of energy in an ecosystem. Visual tools also stimulate curiosity and inquiry, aligning with the constructivist approach to teaching, where learners actively construct knowledge from visual representations and real-life analogies.
Building on this pedagogical advantage, visual instructional materials are increasingly becoming an indispensable part of science education, particularly in the teaching of biology. Their integration into biology instruction is supported by a growing body of research that highlights their capacity to bridge the gap between theory and practice (Egbe & Chima, 2023). Visual tools not only enhance students’ understanding but also promote long-term memory retention, making them valuable assets in achieving educational objectives. Moreover, they serve to demystify complex biological phenomena and encourage learners to develop scientific attitudes and inquiry skills (Kwande & Iwuchukwu, 2022). The emphasis on visual elements in teaching aligns with 21st-century educational trends that advocate for the incorporation of technology and multimedia in the classroom. Thus, the use of visual instructional materials in secondary school biology teaching represents a forward-looking approach that is in harmony with modern pedagogical principles and cognitive theories of learning.
1.2 Statement of the Problem
Despite the recognized importance of biology in shaping scientific literacy and preparing students for careers in science-related fields, the teaching and learning of biology in many secondary schools remain largely theoretical and ineffective. In most classrooms, instructional delivery is dominated by verbal exposition and rote memorization, which often leads to poor conceptual understanding and low academic performance among students (Ikume & Zaman, 2021). This current situation persists even in the face of global educational recommendations that encourage learner-centered and multi-sensory instructional strategies. Ideally, biology should be taught using diverse, interactive, and visual materials that make the subject more engaging and relatable to students’ everyday experiences. However, there remains a noticeable mismatch between the pedagogical ideals for science education and the actual classroom practices observed in many secondary schools, especially in developing countries (Adebayo & Mphahlele, 2022).
Several studies have emphasized the potential of visual instructional materials to transform science education by making abstract biological concepts tangible and comprehensible (Okorie & Tumba, 2023). Nevertheless, there is insufficient empirical evidence on the actual implementation and effectiveness of these materials in the real-world context of secondary school biology classrooms. The current body of literature lacks consensus on the extent to which visual aids are being utilized, the challenges teachers face in adopting them, and their direct impact on student learning outcomes (Nzewi & Akintola, 2021). Furthermore, although some studies advocate for the integration of visual media in science teaching, they often generalize across science subjects, failing to isolate the unique demands and content-specific visual needs of biology. This oversight creates a knowledge gap, particularly in understanding how visual instructional materials specifically influence the teaching and learning of biology in secondary schools.
In light of these concerns, the gap this study seeks to fill is to examine the impact of using visual instructional materials in secondary school biology teaching.

- Curriculum designers should integrate visual instructional materials into the official curriculum for secondary school Biology. This will ensure that visual learning tools are systematically used across all schools, providing equal access to resources that enhance learning.
- Government and educational authorities should allocate more funding for educational resources, including visual instructional materials, to secondary schools. This would ensure that all schools, especially those in underfunded areas, have access to the necessary materials to improve teaching and learning outcomes.
5.5 Limitations of the Study
While the study has yielded valuable insights, several limitations were encountered. Firstly, the study was limited to secondary schools in Ibadan South West Local Government, which may not fully represent the broader educational context across Nigeria. Additionally, the sample size of 165 participants, though adequate for statistical analysis, may not capture the diversity of experiences and challenges faced by students and teachers in different regions. The study also relied on self-reported data from questionnaires, which may be subject to bias, as respondents might overstate or understate their experiences with visual instructional materials. Furthermore, the research was cross-sectional in nature, providing a snapshot of the impact of visual materials at one point in time rather than tracking their effects over a prolonged period. These limitations suggest the need for future studies to explore these issues in greater depth, incorporating more diverse settings and longitudinal designs.
5.6 Suggestions for Further Studies
Future research should explore the effectiveness of visual instructional materials in other subjects beyond Biology, particularly in subjects that involve complex processes and concepts. Longitudinal studies could also be conducted to assess the long-term impact of visual aids on students’ academic performance and retention. Additionally, more research is needed to examine the impact of different types of visual materials (e.g., interactive digital tools versus traditional charts) on student learning in diverse educational contexts across Nigeria.
