Education is the process of facilitating learning, or the acquisition of knowledge, skills, values, beliefs, and habits.

Educational methods include storytelling, discussion, teaching, training, and directed research.

Education frequently takes place under the guidance of educators, but learners may also educate themselves.

Education can take place in formal or informal settings and any experience that has a formative effect on the way one thinks, feels, or acts may be considered educational.

The methodology of teaching is called pedagogy.

In education, a curriculum (plural: curricula or curriculums) is broadly defined as the totality of student experiences that occur in the educational process.

The term often refers specifically to a planned sequence of instruction, or to a view of the student's experiences in terms of the educator's or school's instructional goals.

In a 2003 study Reys, Reys, Lapan, Holliday and Wasman refer to curriculum as a set of learning goals articulated across grades that outline the intended mathematics content and process goals at particular points in time throughout the K–12 school program.

Curriculum may incorporate the planned interaction of pupils with instructional content, materials, resources, and processes for evaluating the attainment of educational objectives.

Curriculum is split into several categories, the explicit, the implicit (including the hidden), the excluded and the extra-curricular.

Professional development is learning to earn or maintain professional credentials such as academic degrees to formal coursework, conferences and informal learning opportunities situated in practice.

It has been described as intensive and collaborative, ideally incorporating an evaluative stage.

There are a variety of approaches to professional development, including consultation, coaching, communities of practice, lesson study, mentoring, reflective supervision and technical assistance.

K–12 (spoken as "k twelve", "k through twelve", or "k to twelve") comprises the sum of primary and secondary education in the United States, Canada, South Korea, Turkey, Philippines, Egypt, Australia, India, Afghanistan and Iran for publicly-supported school grades prior to college.

The expression is a shortening of kindergarten (K) for 4- to 6-year-olds through twelfth grade (12) for 17- to 19-year-olds, the first and last grades of free education in these countries, respectively.

The related term P–12 is also occasionally used in Australia and the United States, to refer to the sum of K–12 plus preschool education.

Natural resources are resources that exist without actions of humankind.

This includes all valued characteristics such as magnetic, gravitational, and electrical properties and forces.

On earth it includes: sunlight, atmosphere, water, land (includes all minerals) along with all vegetation and animal life that naturally subsists upon or within the heretofore identified characteristics and substances.
