Assessment of the effectiveness of ICT-based teaching tools on students’ understanding of plant physiology in senior secondary agricultural science education

Project Abstract

The study investigates how Information and Communication Technology (ICT)-based teaching tools influence senior secondary students’ comprehension of plant physiology within agricultural science education. A quasi-experimental design with a non-equivalent control group was employed across four senior secondary schools, involving 320 students randomly assigned to two groups an ICT-assisted treatment group and a traditional instruction control group. The ICT tools incorporated interactive simulations, virtual laboratories, smartphone-enabled quizzes, digital textbooks, and moderated online discussions designed to enhance conceptual understanding of photosynthesis, transpiration, mineral nutrition, water relations, and hormonal regulation in plant growth. Data were collected through a mixed-methods approach, including pre- and post-tests to measure gains in knowledge, concept map assessments to evaluate structural understanding, classroom observation checklists, and student perception surveys. Reliability coefficients for the knowledge tests and concept maps yielded Cronbach’s alpha values of 0.82 and 0.79 respectively, while the observation checklist demonstrated satisfactory inter-rater reliability (? = 0.77). Quantitative data were analyzed using ANCOVA to control for pre-test differences, and qualitative data from interviews and open-ended survey items were thematically analyzed to capture experiential and contextual factors influencing learning. Results indicated that ICT-based instruction produced significantly greater gains in students’ achievement in plant physiology (F(1, 316) = 9.46, p < .01) compared to traditional pedagogy, with a substantial effect size (partial eta squared = 0.029). Concept maps of the ICT group exhibited deeper hierarchical structures and more interconnections among physiological processes, suggesting improved systems thinking and integrated understanding. Analysis of dialogue in online forums revealed higher frequency of diagnostic questions and evidence-based explanations among ICT participants, indicating enhanced scientific reasoning. Perceived usefulness, ease of use, and engagement levels were positively correlated with achievement gains, highlighting the role of student attitudes in mediating ICT effectiveness. However, qualitative findings also identified challenges, including limited access to reliable devices for a minority of students, occasional connectivity interruptions, and a need for teacher capacity-building to optimize ICT integration, particularly in designing inquiry-driven tasks and aligning digital activities with curriculum standards. Discussion interprets the observed gains as a function of cognitive offloading through simulations, immediate feedback from digital assessments, and collaborative learning facilitated by online tools. The implications for policy emphasize ensuring equitable access to ICT resources, investing in teacher professional development focused on digital pedagogy, and embedding ICT-based activities within the existing agricultural science syllabus to reinforce plant physiology concepts across theoretical and practical domains. The study concludes that well-structured ICT-based teaching tools can significantly elevate understanding of plant physiology among senior secondary students, provided that infrastructural barriers are addressed and instructional design aligns with robust pedagogical frameworks. Recommendations include scalable models for resource provision, continuous teacher training programs, and iterative assessment strategies to monitor and sustain learning gains over time.

Project Overview

What This Project Is About

---

A straightforward look at how using ICT tools, like digital simulations, videos, and mobile apps, can help senior secondary students understand plant physiology better than traditional methods. The project compares learning with ICT tools to standard teaching and checks which approach helps students grasp concepts such as photosynthesis, transpiration, and nutrient transport more clearly.

The Problem It Addresses

---

Many classrooms rely mainly on lectures and textbooks, which can make complex body processes in plants hard to visualize. This project investigates whether ICT-based tools make learning more engaging and improve understanding, retention, and ability to explain plant processes in real-world terms.

Objectives of the Project

---

1. Evaluate students' understanding of key plant physiology concepts after ICT-based instruction compared with traditional methods.
2. Identify which ICT tools are most effective for teaching plant physiology.
3. Measure changes in student motivation and engagement during ICT-assisted lessons.
4. Provide practical recommendations for teachers on integrating ICT in agricultural science classes.

What You Will Do Step by Step

---

1. Review existing studies on ICT in science education. 2. Design two teaching units—one ICT-enhanced and one traditional. 3. Recruit a class of students and obtain consent. 4. Implement the two teaching approaches over a set period. 5. Assess understanding using quizzes, concepts maps, and brief explanations. 6. Analyze data to compare performance and engagement. 7. Collect feedback from students and teachers. 8. Summarize findings and discuss practical implications.

Expected Outcome

We expect ICT-based lessons to improve comprehension, retention, and ability to explain plant processes, along with higher student motivation. The project should yield practical guidelines for incorporating ICT tools in senior secondary agricultural science to enhance learning outcomes.
