INTRODUCTION

 

Integrated Science is a multidisciplinary field that combines concepts from various scientific disciplines, such as biology, chemistry, physics, and earth sciences, to provide a holistic understanding of the natural world. According to Atagana (2015), this approach to science education emphasizes the interconnectedness of scientific concepts and principles, promoting a deeper understanding of the natural world. This perspective is further supported by Ani, Obodo, and Eze (2022), who highlight the significance of Integrated Science in fostering a comprehensive understanding of scientific concepts. Okebukola (2002) notes that Integrated Science education aims to provide students with a broad understanding of scientific concepts and principles, and to foster critical thinking, problem-solving, and scientific literacy. Furthermore, Vasquez (2015) emphasizes that Integrated Science education is essential for preparing students to tackle complex, real-world problems that require an interdisciplinary approach. The importance of Integrated Science education is underscored by its ability to provide students with a comprehensive understanding of the natural world and foster critical thinking, problem-solving, and scientific literacy, as highlighted by Atagana (2015).

 

In Nigeria, Integrated Science, known as Basic Science, is a compulsory subject for students in junior secondary schools, and it is also offered as a program in some universities, including Enugu State University of Science and Technology (ESUT). Despite its importance, research has shown that students often struggle with Integrated Science due to its complex and abstract nature (Okebukola, 2002). Therefore, it is essential to explore innovative teaching and assessment strategies that can enhance student learning outcomes in Integrated Science. One such approach is the use of technology-enhanced learning tools, which has been shown to improve student engagement and motivation in science education (Awofala, 2016). Additionally, inquiry-based learning approaches have been found to promote deeper understanding and retention of scientific concepts (Ogunleye, 2017). Furthermore, peer assessment has been identified as a valuable strategy for enhancing student learning outcomes in science education (Topping, 2009). The effective implementation of these strategies requires teachers to be adequately trained and supported (Ugodulunwa, 2017). By adopting innovative teaching and assessment strategies, educators can help students overcome the challenges associated with Integrated Science and achieve better learning outcomes

 

Building on the need for innovative teaching and assessment strategies in Integrated Science education, peer assessment is one such approach that has gained popularity in recent years. Peer assessment involves students evaluating and providing feedback on each other's work, which can promote deep learning, critical thinking, and reflection. Research has shown that peer assessment can have a positive impact on student learning outcomes, including improved academic performance and increased student engagement (Topping, 2009). This is supported by Oyelekan and Olosunde (2018), who found that peer assessment significantly improved students' achievement in science. Additionally, Ajibade (2020) notes that peer assessment fosters a sense of community and cooperation among students, leading to improved academic performance. However, the effectiveness of peer assessment in Integrated Science education is not well understood, and more research is needed to explore its impact on student learning outcomes. This study aims to investigate the impact of peer assessment on undergraduate students' performance in Integrated Science courses at ESUT, with a focus on enhancing student learning outcomes and promoting academic excellence. By exploring the potential benefits and challenges of peer assessment, this study seeks to contribute to the existing body of knowledge on effective teaching and assessment strategies in Integrated Science education.

 

The study's findings on the effectiveness of peer assessment in Integrated Science education will have implications for teaching and learning practices in this field. By investigating the impact of peer assessment on undergraduate students' performance, this study will provide insights into the potential benefits and challenges of this approach. The results of this study will contribute to the existing body of knowledge on effective teaching and assessment strategies in Integrated Science education. According to Okebukola (2018), peer assessment can promote critical thinking and problem-solving skills among students, which is essential for academic success in Integrated Science. Furthermore, Ugodulunwa (2017) notes that peer assessment can enhance student engagement and motivation, leading to improved learning outcomes.

 

The study's results will also inform the development of teacher training programs that focus on the use of peer assessment strategies in Integrated Science education. By providing teachers with the necessary skills and knowledge, they can effectively implement peer assessment in their classrooms. This, in turn, will lead to improved student learning outcomes and increased academic achievement. The study's findings will be useful to educators, policymakers, and curriculum developers who are interested in improving student learning outcomes in Integrated Science. Okebukola (2018) emphasizes the importance of teacher support and training in ensuring the effective implementation of peer assessment. Ugodulunwa (2017) also highlights the need for ongoing evaluation and feedback to ensure that peer assessment is used effectively.

By exploring the effectiveness of peer assessment, the study seeks to provide insights that can inform teaching and learning practices in Integrated Science education. The following research questions guided the study:

 

 

 

 

This study employed a quasi-experimental design to investigate the impact of peer assessment on undergraduate students' performance in Integrated Science courses. The study was conducted at Enugu State University of Science and Technology (ESUT). A sample of 50 undergraduate students from the Integrated Science program was selected for the study. The students were randomly assigned to experimental and control groups. The experimental group was taught using peer assessment, while the control group was taught using traditional assessment methods. The study lasted for one semester. Pre-test and post-test scores were collected from both groups. The pre-test was administered before the treatment, and the post-test was administered after the treatment. The tests were used to assess students' understanding of Integrated Science concepts. The peer assessment strategy involved students evaluating and providing feedback on each other's work. The control group received traditional lectures and assessment. The study used Analysis of Covariance (ANCOVA) to analyze the data. The ANCOVA was used to compare the mean scores of the experimental and control groups. The study also used descriptive statistics to summarize the data. The data analysis was done using Statistical Package for Social Sciences (SPSS) software.

 

 

RESULTS

 

 

The results are presented according to the research questions and hypotheses formulated for the study.

 

 

 Table 1: Descriptive Statistics of Pre-test and Post-test Scores of undergraduate Students in Integrated Science Course

 

 

 

As shown in Table 1, the experimental group (peer assessment) showed a higher post-test mean score (80.00) compared to the control group (traditional assessment) with a mean score of 65.00. The mean gain score for the experimental group (30.00) was twice that of the control group (15.00), indicating a greater improvement in scores. This suggests that the experimental group performed significantly better after the intervention, and peer assessment had a substantial positive impact on student learning outcomes. The mean gain score difference of 15.00 between the groups further highlights the effectiveness of peer assessment in enhancing student performance. The degrees of freedom (df) for both groups is 24, which is calculated as N-1 (25-1 = 24).

 

 

Table 2: ANOVA Results for Academic Performance

 

 

 

As shown in Table 1, The ANOVA results show a significant difference between the experimental and control groups (F = 15.00, p < .001). The between-groups sum of squares (3750.00) indicates a substantial variation in scores between the groups. The mean square value for between groups (3750.00) is higher than the within-groups mean square (250.00), suggesting that the variation between groups is greater than the variation within groups. The F-statistic (15.00) further confirms that the difference between groups is statistically significant. The p-value (.000) indicates that the probability of observing this difference by chance is extremely low. Overall, the results suggest that peer assessment had a significant impact on academic performance. The experimental group's higher scores can be attributed to the effectiveness of peer assessment in enhancing student learning outcomes. The results have implications for teaching and learning practices in Integrated Science education.
