The quality of the internal physical environment of a school is critical in enhancing the achievement of learning outcomes and therefore the actualization of competency based curriculum in schools. The main objective of this study was to establish the relationship between the internal schools' physical environment and student achievement in public secondary schools in Nairobi City County. The purpose of the study was to assess the influence of the internal environment of schools on the attainment of learning outcomes. The study sought to empirically fill the knowledge gap of establishing the strength of correlation between schools' internal environment and learning outcomes. The study employed ex facto research design targeting a population of 75(N) public secondary schools. Using stratified, systematic and simple random sampling techniques, the study drew a sample size of 39 (n) schools from the study population. A revised Commonwealth Association of Physical Environment (CAPE) questionnaire was used to collect data for the study. The study revealed that the school environment influenced the learners' achievement as manifested in the test scores; (Pearson's r, there was a positive correlation between the school environment and student achievement; r = 0.370, n = 35, p = 0.029). The study concluded that school physical environment contributes to student achievement. A framework of redesigning school facilities was therefore suggested with key features of; cost effectively upgrading old facilities, improving school grounds and controlling physical development around educational facilities.

Public open spaces form an important part of life, giving services to people and protecting the urban environment. Ineffective standards for establishment, of public open spaces have always been a stumbling block in ensuring their sustainability, hence the existence of non performing unplanned, and poorly distributed public open spaces. This study sought to establish the types of public open spaces in Machakos municipality, Machakos County. The study aimed to characterize the typologies of public open spaces in order to understand the underlying reasons for how they came to be. Primary and secondary data sources were used to get the information. Primary data gathered using questionnaires, interview schedules, observation schedules and photographs. Secondary data on the other hand was gathered through review of existing literature materials and documentations of public open spaces from the county government blueprints and policy documents. . The findings revealed that there are a number of public open spaces in Machakos Municipality, with Machakos Peoples park as the most popular of these open spaces.
