Abstract: The acceleration of urbanization has highlighted the stress problems among college students, making environmental interventions to promote physical and mental health an important direction in campus health landscape research. However, the current research faces issues such as weak sample specificity, single indicators, and the absence of saturation variables, making it difficult to support precise design of campus healthy landscapes. Therefore, this study, targeting college students, employed a randomized controlled experiment to set up visual exposure scenarios with low and high saturation green and purple plants, as well as a control group without plants. The purpose of the study is to provide scientific evidence for campus plant landscape design and stress intervention for college students Measurements included systolic blood pressure, diastolic blood pressure, pulse, and Self-Rating Anxiety Scale (SAS) scores, to explore the effects of plant color saturation on physiological and psychological recovery. The results showed that visual exposure to plants effectively reduced blood pressure and anxiety levels, with low saturation plants providing better restorative benefits than high saturation and the control group. Specifically, low saturation green performed better in improving systolic blood pressure, while low saturation purple had advantages in diastolic blood pressure, pulse, and anxiety relief. The study indicates that color saturation is a key visual factor affecting the restorative effects of plant landscapes, providing references for optimizing campus health environments.

Abstract: The study examined psychosocial metrics and students’ academic performance in Biology in secondary schools in Nsit Atai Local Government Area, Akwa Ibom State. The study was guided by two research questions and two research hypotheses. A correlational research design was adopted for the study. The population of the study consisted 2635 Senior Secondary Two (SS II) Biology students in public secondary schools in Nsit Atai Local Government Area. A sample size of 328 Biology SS II students obtained using Taro Yamane’s formula was used for the study. A simple random sampling technique was used in selecting the sample size for the study. Two researcher developed instruments were used in collecting data for the study. The instruments were tagged “Psychosocial Metrics Questionnaire (PMQ) and Biology Performance Test (BPT)”. The instruments were duly validated by three experts in Faculty of Education, University of Uyo, Akwa Ibom State. After which Cronbach Alpha statistics was used in obtaining reliability coefficients of 0.82 and 0.84 for the PMQ and BPT respectively. Pearson Product Moment Correlation Statistics was used in answering the research questions and in testing the hypotheses at 0.05 level of significance. The findings of the study revealed that peer pressure and anxiety significantly predict students’ academic performance in Biology in secondary schools in Nsit Atai Local Government Area, Akwa Ibom State. Recommendations made among others included; Biology teachers should adopt instructional approaches, such as practical activities, real-life applications and instructional technologies to improve students’ academic performance. Also, schools should adopt supportive teaching strategies and provide effective guidance services to help reduce students’ academic anxiety in Biology.
