Overview of Public Education System

The quality of education is one of the most debated issues at all levels globally. The government agencies and the local communities struggle to control education system to ensure that quality learning outcome is attained. In the current world, we believe in a competitive environment that allows the private, public, charter, parochial and alternative schools to compete healthily in the education sector, but parents choose the best education system that suits their children.  The features of public education system include: samedayessay

Ø  In public education system, the government sets the overall standards of education and supervises them through a board of regents, colleges or universities.

Ø  The funding of public education system comes from the local, state, and the federal government. This is because the largest portion of the revenues for public schools comes from the local property taxes and the resources they have for every student vary widely depending on the availability of the resources.

Ø  The curriculum decision-making process in public education systems are largely made at the local and state levels; the federal government has a limited influence towards the curriculum. Locally elected school boards run and manage the operation of the public education systems at district levels.

Ø  The funding of public education system from the local taxes may have disadvantages depending on the state of the economy in various cities. These disadvantages may be improper electives of the students' interests and desires. Also, the system can cause inequality to students because the system does not provide the essential classes to obtained general education development that ensures the learners to pursue higher education system or obtain the job.

The public two-foot system is grouped into two forms. The first system is principally based on the wealthier urban jurisdiction, and it is considered to be the best as it does not fail the expectation of the students. The second system is principally based in poorer urban and rural areas, and it is indeed considered to be in crisis because quite a good number of students in this system are dropping out of school before graduation. Too many of the students are receiving school certificates that do not certify academic confidence in main subjects, and too many of the learners are left unprepared for the work in the world. In this regard, this system of public education is indeed in crisis, and they need emergency treatment to ensure student's expectations are attained. In conclusion, there are essential gaps that exist regarding resources between the poorer and the wealthier jurisdictions in the provision of public educations to the society including financial support and pupil enrollment and per expenditure which in turn have the direct impact on the academic outcome of the students.  Thus, good leadership, a solid academic curriculum for all learners, school safety and discipline, quality of teachers, support from the community, and ensuring a culture of learning should be emphasized at all public schools to ensure the existing gaps between the two forms of education regarding resources is reduced.



What Is the Basic Role of Education Administrators?

Education administrators are employed in colleges, schools, universities, daycare centers and preschools. Their primary job role is managing the activities and providing pedagogical leadership at these kinds of institutions. On the other hand, education administrators are also employed in the museums, businesses, for directing their educational programs. Education administrators work in a different level of education. Their areas of expertise include hiring and supervising staff, managing budgets and making important decisions that will affect the academic community. Education administrators are also in charge of developing mission and a direction for the facility at the area of their work. It has been witnessed that the actual job responsibility for the education administrators will vary from institutions to institutions depending upon their employment. For instance, in school, the job role of the education administrators is of assistant principal or principal. For the businesses and private schools, they may be employed as the head master or the director. For universities and colleges, the education administrators are hired as the respective department heads, deans, admissions officer, etc. And for museums and libraries, education administrators act as an instruction coordinator. The main responsibilities of education administrators include setting high standards and educational aims. Education administrator acts as a supervisor for the managers, and they are supportive towards other faculties such as coaches, teachers, librarians, etc. An example of daycare can be taken into account where there is only one education administrator who is in charge of all of the duties mentioned above. It has been observed that in the large schools and universities there are various education administrators who share the same workload. Each of them has a particular responsibility. Some of the prominent education administrator responsibilities are as follows:

  • Education administrators are in charge of the guidance programs that are done for the students for managing their services.
  • Education administrators handle the relationships with students, parents, employers, and the community in which they work.
  • Education administrators also manage budget efficiently so that the financial systems are followed smoothly.
  • Education administrators take part in the entire gamut of the recruitment process and the marketing activities of the educational institutions. 
  • Education administrators work in the communities that include the governing bodies, task groups, and board.
  • Education administrators contribute towards the planning and policies of the educational institutions.
  • Interestingly education administrators also facilitate a large variety of social and educational activities.
  • Education administrators provide the administrative support to the academic group of tutors, teachers, and lecturers.

Why Does Everyone Need Education Administrators?

The importance of education administrators in the educational field cannot be quantified. The educational system is not complete without the education administrators. The roles and responsibilities in the academic field that is handled and managed by the education administrators cannot be compared with any other person in this field. Education administrators are the backbone/pillar of the educational institutes without them the complete educational system will collapse. Education administrators are engaged in the day-to-day activities in the educational field, so they are one of the important tools in the educational system

Photocatalysis of Dimethylnaphthalene

Selective Photocatalysis of Dimethylnaphthalene by Means of β-Cyclodextrin Molecular Recognition Sites (PDF 246kB)

Heterogeneous photocatalysis using titanium dioxide is a non-selective technique used for the degradation of target molecules such as dimethylnaphthalene. This work presents a novel approach for selective photocatalysis implementing molecular recognition sites (MRS) placed in the vicinity of titanium dioxide which attract target molecules and shuttle them to the surface of titanium dioxide, where they are more rapidly and selectively degraded.
