The Bohr model for beryllium is a simplified representation of a beryllium atom where electrons orbit the nucleus in circular orbits at specific energy levels. In this model, beryllium has four electrons arranged in two energy levels or shells, with two electrons in the inner shell and two in the outer shell. The Bohr model helps to explain the electronic structure and properties of beryllium.

The four largest satellites of Jupiter, known as the Galilean moons (Io, Europa, Ganymede, and Callisto), were discovered by Galileo Galilei in 1610. Using a telescope, Galileo observed these moons orbiting Jupiter, providing evidence against the geocentric model of the universe and supporting the heliocentric model proposed by Copernicus. This discovery revolutionized our understanding of the solar system.

Wheeler's Model of Curriculum Design contains five stages while Tyler's Model only contains four. Also, Wheeler's model is cyclic and Tyler's model is linear. The only real similarity is the fact that they are both curriculum design models.

explain with the help of diagram circular flow of income model in a four sector economy?
1).The Taba curriculum model has seven steps while Tyler curriculum model have four steps. 2).the first step in Taba curriculum model is diagnosis of needs while the first step in Tyler curriculum model is stating of the objectives.
Walker's model of curriculum development is a cyclical process that involves four main stages: planning, development, implementation, and evaluation. It emphasizes the importance of collaboration among stakeholders, such as teachers, students, and community members, in designing a curriculum that is relevant and effective for the learners. The model encourages ongoing reflection and revision based on feedback and results from the evaluation stage to continuously improve the curriculum.
explain the importance of each of the four steps in a simple decision-making models?
Tyler's model of curriculum design is linear and prescriptive, with four key components: objectives, content, learning experiences, and assessment. Tabas' model focuses on students' experiences and emphasizes the importance of considering context, values, and reflection in curriculum design. Both models are used to guide the development of effective educational programs.
explain the importance of each of the four steps in a simple decision-making models?
Tyler's model emphasizes the objectives of education, starting with identifying specific learning goals and outcomes, followed by designing instruction to achieve those objectives. Wheeler's model, on the other hand, focuses on the process of curriculum development through continuous cycles of planning, implementation, and evaluation, involving all stakeholders in the decision-making process. Tyler's model is more linear and prescriptive, while Wheeler's model is more holistic and iterative.

Definition The Tyler model of curriculum was developed by the American educator Ralph Tyler in the 1940s, while the Wheeler model is a cyclic model of curriculum developed by D. K. Wheeler in 1967.Phases Tyler’s model has four main components: objectives, selection of learning experiences, organization of learning experiences, and evaluation. Wheeler’s model, on the other hand, has five phases: aims, goals, and objectives; learning experiences; selection of content; organization and integration of learning experiences and content; and evaluation. Evaluation Although both models have an evaluation phase, in Tyler’s model, evaluation is terminal since it is the last phase in a linear model, but in the Wheeler model, evaluation is not terminal. However, in the Wheeler model, the feedback from the evaluation phase is fed back into objectives and goals. Content and learning experience In the Tyler model, there is no separate component for “content” while in the Wheeler model, content is separated from the learning experiences from which it’s developed. The key difference between the Tyler and Wheeler models of curriculum is that the Tyler model fundamentally comprises four concepts and is a linear model adapted for curriculum development, whereas the Wheeler model comprises five theories and was developed as a cyclical model.
