Abstract

This research explores ecological and social transformation in the Americas with a focus on the impact of economic policies on the environment from the colonial era to the present. Through historical analysis, this research examines how economic policies implemented by colonial powers, governments, and the private sector have influenced the continent's natural ecosystems and social structures. It found that intensive exploitation of natural resources, the introduction of unsustainable agricultural practices, and rapid industrialization have resulted in significant environmental degradation, including deforestation, loss of biodiversity, and pollution. In addition, economic policies have also triggered profound social changes, such as mass migration, urbanization, and changes in society's work structure. This study highlights the importance of a more sustainable and inclusive economic approach to reduce negative impacts on the environment and society. Thus, this research provides important insights for policy makers in designing economic strategies that are more harmonious with ecological sustainability and social welfare.

Abstract

This study aims to describe the feasibility of e-booklet learning media to improve student learning outcomes on parabolic kinematics material, describe the improvement of student learning outcomes after using e-booklet learning media on parabolic kinematics material, and describe students' responses to the e-booklet learning media that has been developed on parabolic kinematics materials. The method used is RD, using the ADDIE model. The results of the study showed: (1). Validation of media feasibility obtained a score with a percentage of 87.26%; (2) N-gain obtained a value of 0.77; (3) the assessment of student responses to the media, the benefit aspect, in total obtained a percentage of 89.14%. Based on the results, it can be concluded that the use of e-booklet learning media is very feasible to be used for parabolic kinematics material, to improve student learning outcomes, and received a very good response from students.
