Abstract
The objective of the study was to determine the cognitive attributes, physical aspect and psychosocial aspects of students’ learning environment on their science performance. A total of one thousand one hundred twenty-three Grade 10 science students in six divisions of Region X, Philippines participated in the study. A triangulation technique was applied in which data were obtained from the survey instruments, semi-structured interview, class observation and literature review to ensure the validity and accuracy of the results of the study. This study utilized descriptive correlational and causal comparative research design. The results revealed that students performance in science was of low mastery level with a very satisfactory average grade during elementary, having a satisfactory average of all the science subjects taken from Grade 7 to Grade 9 and with a description of moving towards mastery in their scientific ability of the National Career Assessment Examination (NCAE) result. In the psychosocial aspects, the participants generally practiced their science activities in both laboratory and classroom environments. They possessed moderate confidence in their emotion and self-efficacy in chemistry, having average science process skills and with very satisfactory science teachers. Cognitive attributes such as Junior high school science general weighted average, elementary general weighted average, and National Career Assessment Examination result and psychosocial aspects like classroom learning environment and teacher quality were significantly correlated with science performance of which the Junior high school science average (β = 0.194), elementary average (β = 0.096) and classroom learning environment (β = 0.132) were the predictors of science performance. The study puts forth the notion that the most fitting structural model of students’ performance in science is when it is anchored on the cognitive ability of the students and supported by their physical aspect of science leaning environment. Students with high cognitive ability supported by conducive, well-equipped physical facilities in science, expectedly perform better. It is recommended that the stakeholders may anchor their learning modules and activities on the different levels of learners’ cognitive abilities and needs.

Published: October 2019

Abstract
The environmental degradation that occurred in the past and continues nowadays is a failure of our society and education system in providing the understanding and skills needed by students. Schools and teachers have the responsibility to develop students’ literacy skills, especially ecological literacy. Therefore, to achieve that purpose, the availability of teaching materials with ecological literacy is needed. This research aims at explaining the ecological literacy values in four Indonesian language textbooks for senior high school students based on 2013 curriculum. To examine the ecological literacy values both descriptive and distributive, content analysis is used as the main method. The study used a mixed approach to analyze both qualitative and quantitative data in a single study. Based on the analysis result, the ecological literacy values include (1) ecological knowledge (general knowledge, socio-political systems, and environmental issues), (2) affective tendency (factors within the individual), (3) behaviour (assumption of personal responsibility and self-control), and (4) cognitive skills (related to environmental issues). However, the content of ecological literacy value is more dominant on materials dealing with ecological knowledge and has not emphasized on all other components. Furthermore, the analysis of the passage about knowledge component contains the most comprehensive information of all.

Abstract
This study aims to determine the effect of self-regulation on the ability of motion coordination of elementary school students. Motion experience and physical activity in elementary school children proved to have a positive effect on children’s physical, psychological, and social development. In addition, physical education in elementary schools is oriented to laying down the foundations of basic movement and movement, so that in the future, children will grow-up and develop into complete personalities that are in harmony and in harmony with age. Coordination ability is one of the basic components of motion. Self-regulation is internal motivation, which results in the emergence of a person’s desire to determine goals in his life, planning strategies to be used, and evaluating and modifying the behaviour that will be carried out. The method used is a quasi-experimental method that examines the effect of self-regulation on coordination ability of elementary school students. The instrument used for data retrieval on the variable of self-regulation is a questionnaire, while the variable of ability to coordinate the motion used the test. The results of this study show that self-regulation contributes to the ability to coordinate motion. Self-regulation of elementary school students has a varied contribution to the components of motion coordination, namely: the ability to assemble movements, distinguish, the ability to maintain balance, the ability to maintain balance, adapt movements, find and maintain the rhythm of movement, react and change direction.
