Abstract
This study investigated the efficacy of multimedia instruction on students' interest and academic achievement in Christian Religious Studies (CRS) in Edo State, Nigeria. Adopting a quasi-experimental pretest–posttest non-equivalent control group design, 156 students from four public secondary schools participated. The experimental groups received multimedia-based instruction integrating audio, video, text, animations, and interactive exercises, while the control groups were taught using conventional lecture methods. Data were collected using the Christian Religious Studies Achievement Test (CRSAT) and the Christian Religious Studies Interest Scale (CRSIS), and analyzed using descriptive statistics and independent samples t-tests at a 0.05 significance level. Results indicated that students exposed to multimedia instruction achieved comparable outcomes in both interest and academic performance to those taught via traditional methods, with no statistically significant differences observed. These findings suggest that multimedia instruction is a viable alternative to conventional teaching in CRS, offering potential for enhancing engagement and instructional quality when effectively integrated into classroom practice.

Introduction
Christian Religious Studies (CRS) occupies a strategic position in the Nigerian secondary school curriculum, designed to inculcate moral consciousness, spiritual values, and responsible citizenship through biblical teachings and Christian ethical principles. Despite its importance, students' interest and achievement in CRS have continued to decline. Several scholars attribute this trend largely to the persistent use of teacher-centred instructional approaches that fail to actively engage learners or make learning meaningful. Many Nigerian students perceive CRS as abstract, monotonous, and disconnected from their lived experiences, leading to low motivation and poor academic outcomes. Multimedia instruction has been proposed as an innovative instructional strategy capable of stimulating learners' curiosity and sustaining their interest by integrating text, graphics, audio, video, and animation to present content in ways that appeal to multiple sensory channels.
Theoretical Framework
This study is anchored on the Multimedia Learning Theory developed by Richard E. Mayer and supported by Bloom's Taxonomy of Educational Objectives. Multimedia Learning Theory explains that learners process information through visual and auditory channels, based on three assumptions: dual-channel, limited-capacity, and active-processing. The theory suggests that multimedia instruction improves understanding by presenting information through both channels and reducing cognitive overload. It also encourages active engagement, where learners select, organize, and integrate information with prior knowledge. In CRS teaching, multimedia tools such as images, audio, and videos help students better understand biblical teachings. Bloom's Taxonomy further supports this by promoting higher-order thinking skills such as analysis, evaluation, and application of Christian values.
Methodology
The study adopted a quasi-experimental pretest–posttest non-equivalent control group design. The population comprised 1,503 Senior Secondary School II students from public secondary schools in Ovia North-East Local Government Area, Edo State. A sample of 156 students was drawn using multistage sampling from four schools, with 84 students in experimental groups and 72 in control groups. The experimental groups received multimedia-based instruction integrating audio, video, text, animations, and interactive exercises, while control groups received conventional lecture-based instruction. Two instruments were used: the Christian Religious Studies Achievement Test (CRSAT) with reliability coefficient of 0.88, and the Christian Religious Studies Interest Scale (CRSIS) with reliability coefficient of 0.89. Data were analyzed using descriptive statistics and independent samples t-tests at 0.05 significance level.
Results
Hypothesis one testing revealed that the posttest mean interest score for the control group (M = 4.7, SD = 1.15) and the experimental group (M = 4.7, SD = 1.06) were very close. The independent samples t-test result was not significant (p = .416), indicating no significant difference between the posttest mean interest scores of CRS students taught using multimedia instructional package and the control group. Hypothesis two testing showed that the posttest mean achievement score for the control group (M = 1.60, SD = 0.56) and the experimental group (M = 1.70, SD = 0.65) were also very close. The t-test result was not significant (p = 0.361), indicating no significant difference between the posttest mean achievement scores of the two groups. Both null hypotheses were therefore accepted.
Discussion of Findings
The finding that multimedia did not significantly increase students' interest in CRS beyond what was achieved through conventional instruction diverges from some previous studies but aligns with Sung and Mayer's argument that it is not the medium itself but how it is applied that determines effectiveness. If multimedia is poorly integrated—limited to slideshows or passive viewing—it may not meaningfully enhance learners' situational interest. The absence of a significant difference could be linked to short exposure, limited interactivity, or teacher inexperience in integrating multimedia effectively. Similarly, the finding that multimedia did not significantly improve academic achievement in CRS compared to traditional teaching suggests that multimedia cannot compensate for weak instructional design or inadequate teacher preparation. The subject nature of CRS, which requires moral reasoning, textual interpretation, and abstract thinking, may also explain this result, as multimedia limited to slides without deeper engagement would have minimal effect on achievement.
Conclusion and Recommendations
The study concludes that multimedia instructional packages are effective tools for teaching Christian Religious Studies but do not necessarily produce superior outcomes in students' interest and achievement when compared with conventional teaching methods. However, multimedia instruction was found to be as effective as the traditional method, indicating that it is a viable alternative instructional strategy in CRS classrooms. Effective multimedia integration requires appropriate pedagogical strategies, teacher training, and supportive learning environments. Teachers of CRS should be trained on effective multimedia integration through workshops and professional development programmes. School administrators should provide adequate technological facilities to support multimedia-based instruction. Curriculum planners should promote blended instructional approaches that combine multimedia with learner-centred teaching strategies. Further studies should examine the long-term effects of multimedia instruction on students' moral development and value formation.
