Cultivating Model-Based Reasoning in Science Education

I often use model in my classes. Especially I need to describe the structure of the abstract or very small size concepts. We use the models that must be realistic. It is too important for the learning concepts. Otherwise misconceptions can be consist by the students. At the same time models provides students motivation.

“G = m.g”  Is it a model?

Cultivating Model-Based Reasoning in Science Education

Model-Based learning rather active students in the process of learning by making some different artifacts. The aim of this learning model begins with that students find their own question. Then students answer this question by developing model themselves. In this process , students facing new question . Thus students have more in depth information. And this artifacts could wide variety of ways like ballons , computer programs or something related nature. In somuch that this model combines mathematic and science. For example ; students find by calculating the distance of the load in the hand location of the elbow from the antomical structure of human body by taking advantage of momentum. Model - based learning provide benefits for teachers. Because teachers have facility observe development process of students.

1-) What is the process that provide students to find their own question ?
2-) What could teachers do when students have difficulties in finding answer to question ?

This article focus on model-based reasoning in science education. In my opinion this approach is an expected result of science nature. Curiosity, imagination and the effort of modeling the problems are the best reasons and the best result of the science. And the role of the teacher’s is clarified in this approach. The most significant idea in this article is that the modeling based reasoning is the common side of all science disciplines (education, history, engineering or ex.)

Questions:

        1)   Which kind of analogy is better the more digital based or more interactive one?

        2)    How can we modified the existing learning environment as suitable with model based reasoning approach ?

Model-based reasoning  contain a wide range of approaches and disciplines. For instance laboratory, history, ethnographic and pedagogical studies. Model-based reasoning has a goal that how students cultivate effective model or analogy. For example first graders students think that own fingers simulate popsicle sticks although they don’t think elbow model. But third grade students could think elbow model. Analogical mapping four types in model- based reasoning. There are physical microcosms, representational systems, syntactic models, and emergent models. All of these model types provide pose a questions, evaluate, revise, apply scientific method/process, deeper understanding, and defend own idea for students.  So that,  students obtain epistemic information. It shouldn’t be forgotten students work in small groups, they discussion their model’ s weaknesses and strengthnesses feature.  Students should be coordinated and should have different ideas. My questions:

How teacher manage classroom when student collect data?

When students present their solving if they persuade error epistemic  other students how teacher act?

The approache encouraged students to generate and test their own causal conceptual models of scientific phenomena. In addition, there was an equal emphasis on leading the classroom members to monitor and reflect on their own progress in achieving this goal. The general intent was to scaffold for students a shift from the more typical role of following a prescr ibed sequence of activities dictated by the curriculum and teacher to one in which students became increasingly  capable devoloping their own experimental and observational plans for testing the adequacy of their current theory, comparing their theory and findings to those generated by others and then revising the model to improve its generality and predictive power.An emphasis on modeling entails changes

in students’ epistemic goals. Rather than working to find answers to questionposed by curiculum

designers or teachers, students learn to pose, evaluate, and pursue worthwhile questions of their own

 

 

Questions:

1)How do we use analogical mapping effectively during science lesson?

In accordance with modeling perspective, a vital result of a students’ career requires that  they must be equipped with  extensible, general, and mathematically powerfull models.  It underlines the fact that science should not be ignored in any case. Unless a model is composed of without something,  one can not take up an activity. On the way of preparation process for a model,  content must be taken into account.

Modeling necessiates the fact that students  must have capability of evaulating, posing and pursuing  the questions that are worthwhile rather than only finding out the correct answer.

Article discussed the importance of thinking in science-based teaching model.Modeling should be something that associated with a frequently asked question and reaching results.Model based thinking is useful for both teachers and students.Modelling allows for students ideas to visualize teachers.Models should be selected taking into consideration the students' patentials. Students can create their own problems evaluate and follow their learning .In spite of  students are able to contribute to those pre-receiving ,they create their own models by being creative.It provides that students can create their own models not as a appliers of the models that are in text books of students.
Question:1-How can model based learning use in classrooms?
              2-What is the role of teachers on model-based learning?

This section describes the model-based reasoning approach to science education. Scientists who are working on this issue, and these scientists into practice. For example, Gentner and Gentner electrical circuits implemented on the models. Analogical models have been used for this. Analogies can be developed to serve as an important guideline modeling. This approach is that the real question is looking for children to understand the natural world through the invention of models can be achieved by participating in scientific applications? The nature and objectives of the models is determined by the modelers. Creates an effective starting point for modeling the physical Microcosms.
Models are often referred to as representation systems and represent the evolving capacity of the child evolves. In this approach, student works with small working groups.To ask questions, research questions and tries to convince members of the group. According to the group’s ideas and criticism, and offers its own model layouts. The teacher in the classroom, not the distributor information serves as a guide to encourage ideas that support. Modeling approach becomes more fun and learning. Modeling approach becomes more fun and learning. Modeling is of great importance both for the student and for the teacher. So that teachers will refer student to think and to use scientific process skills, and will guide the students. Model-based learning, student make the construction of scientific models and better understanding of the nature of science.

Questions:

1. How do I set up classes in accordance with the model-based learning approach in schools? What should be the role of the teacher in these classes?

2. What is the place of physical microcosms model-based learning?
