1.1 Introduction
Educational technology refers to the use of digital tools, resources, and strategies to facilitate teaching and learning processes (Ololube, 2013). In the context of science education, educational technology is particularly significant as it allows for the visualization of complex scientific concepts, simulation of experiments, and interactive learning experiences that are often difficult to achieve through conventional teaching methods (Anyanwu, 2018). Integrated Science is a multidisciplinary subject that combines elements of physics, chemistry, biology, and earth science to provide students with a comprehensive understanding of scientific principles and their real-world applications (Akinbobola & Afolabi, 2010).
The teaching and learning of Integrated Science require both conceptual clarity and practical engagement to develop critical thinking, problem-solving skills, and scientific literacy among students. Traditional teaching methods, which rely heavily on lectures, textbooks, and teacher-centered approaches, is often inadequate for fully engaging students or fostering deep understanding of scientific concepts (Adeyemo, 2017).
As a prelude to other parts of this study, this chapter will discuss the background upon which this study was initiated, the statement of problems that led to this study, the aim and objectives of the study. Others are significance of the study, scope of work, research hypothesis and questions, limitation of the study and definition of terms.
1.2 Background of Study
The integration of technology into education has evolved significantly over the past century, reflecting changes in both pedagogical approaches and technological advancements. The early use of educational technology was largely limited to simple audio-visual aids such as chalkboards, overhead projectors, and film strips, which provided basic support for teaching and learning processes (Roblyer & Doering, 2013).
Educational technology has emerged as a pivotal tool in modern teaching and learning, offering innovative methods for enhancing educational delivery and student comprehension. According to Ololube (2013), educational technology is the systematic application of digital tools, multimedia resources, and instructional strategies to improve teaching and learning outcomes. It has been reported that the effective integration of technology into classrooms can lead to improved student engagement, motivation, and understanding of complex concepts (Anyanwu, 2018). In science education, particularly in Integrated Science, such technological interventions are essential because the subject demands practical demonstration, conceptual clarity, and analytical thinking (Akinbobola & Afolabi, 2010).
Researchers have asserted that traditional teaching methods, which are predominantly teacher-centered, often fail to meet the cognitive and practical needs of students in science subjects. Adeyemo (2017) stated that reliance on lectures and rote memorization in teaching Integrated Science has resulted in low student achievement and minimal interest in scientific inquiry. Similarly, Chukwuemeka (2019) affirmed that the absence of technological tools in science classrooms limits opportunities for interactive and experiential learning, which are crucial for developing problem-solving skills and scientific literacy among students.
Oyelade (2021) contended that schools that implement educational technology in science teaching report notable improvements in student participation, comprehension, and academic performance. The use of simulations, virtual laboratories, interactive whiteboards, and multimedia presentations allows students to visualize abstract scientific concepts and engage in activities that reinforce theoretical knowledge. According to Anyanwu (2018), such tools create a learner-centered environment where students actively construct knowledge rather than passively receive information.
Ololube (2013) stated that inadequate infrastructure, inconsistent electricity supply, poor internet connectivity, and lack of trained teachers often impede the integration of technology in classrooms. Additionally, Chukwuemeka (2019) affirmed that high costs of technological devices and resistance to change among educators further exacerbate the difficulty of sustaining technology-enhanced learning environments. This study is set against the backdrop of exploring how educational technology influences the teaching and learning of Integrated Science.
1.3 Statement of Problems
Investigation revealed that the teaching and learning of Integrated Science in Nigerian secondary schools is faced with numerous challenges that hinder effective knowledge acquisition and skill development. Traditional teaching methods, which heavily rely on lectures and rote memorization, is often inadequate for engaging students and fostering conceptual understanding. Studies indicate that students struggle to connect theoretical knowledge with practical applications, leading to poor academic performance and diminished interest in the subject (Adeyemo, 2017; Olaitan & Agwagah, 2019).
Additionally, the rapid advancement of educational technology presents an opportunity to enhance the teaching and learning process. The integration of digital tools, multimedia resources, and interactive platforms is increasingly recognized as a means to stimulate student engagement, and support active learning (Anyanwu, 2018). On the other hand, some schools that have adopted educational technology report improvements in students' participation, and academic outcomes (Oyelade, 2021).
Furthermore, challenges such as limited access to electricity, internet connectivity issues, and high costs of technological tools exacerbate the difficulty of implementing these innovations across all schools (Chukwuemeka, 2019). It is against this backdrop that this study seeks to investigate the impact of educational technology on the teaching and learning of Integrated Science.
