SET INDUCTION ENHANCE STUDENTS INTEREST LEARNING IN SCIENCE

Abstract

The purpose of this study is to examine the effects of applying different type of set induction on students interest, attention and motivation level. Participants will be Year 5 students from who will receive 1 hour weekly different type of set induction along with their regular science lesson. The set induction that i was used in this study was story telling and games like activity. During the lesson teacher will observe my lesson to measure the students interest, attention and motivation level and teacher’s creativity level. I also took video recording and to gauge their interest, attention and motivation level about using different type of set induction.

1. Introduction

I realized that ineffective set induction makes the students to become passive learners during my teaching and learning process. I planned to improve my poor set induction phase by applying different type of activity to get involve the students participation by enhance their motivation, interest and attention level. The objective of my studies is develop set induction phase to develop the set induction phase to (1) increase pupils motivation, interest and attention to learn science and (2) develop my creativity level in carry out set induction to enhance pupils participation in learning and teaching progress.

2. Procedure

I carry out my study for four week, in which one period per week. I implimented two types of set induction activity which is story telling and games like activity. I used three types of instrument that is questionnare to tests on the students opinion as well as their likes and dislikes about the set induction in teaching and learning process. Second instrument was observation, where teacher will assess pupils performance and teacher’s creativity level. I also video recorded the set induction phase to observe pupils interest, attention and motivation level....

...Hume’s Problem Of Induction
In A Treatise of Human Nature, Hume challenges the traditional theories of causality, the idea that one can make an observation about two events and infer a new claim concerning the conjunction of the first event and the “resulting” second event. Instead of accepting this notion of causality, Hume questions the certainty of matters of fact and more specifically induction. Hume states there are two distinct types of knowledge: relations of ideas and matters of fact. Relations of ideas are products of deductive, truth-preserving inferences. For instance, the statement 2+2=4 will always be true and cannot be negated without contradiction. Hume denotes relations of ideas as ‘a priori’ , ideas that can be known without experience. On the other hand, matters of fact are products of inductive reasoning that can be negated with contradiction because they may only be known through experience. Hume reckons that experience doesn’t prove very much because the future cannot be proven by the past. Even though we have seen something over and over again, doesn’t mean that it will happen tomorrow or the next day after that. For instance, one could conclude the sun will rise tomorrow morning based on the observation that it has risen every morning of our existence. Yet, this relationship between the morning and the sun rising “leaves not the lowest degree of evidence in any proposition” (Hume 267) that goes beyond our present...

Asymmetric induction
From Wikipedia, the free encyclopedia
Asymmetric induction (also enantioinduction) in stereochemistry describes the preferential formation in a chemical reaction of one enantiomer or diastereoisomer over the other as a result of the influence of achiral feature present in the substrate, reagent, catalyst or environment.[1] Asymmetric induction is a key element in asymmetric synthesis.
Asymmetric induction was introduced by Emil Fischer based on his work on carbohydrates.[2] Several types of induction exist.
Internal asymmetric induction makes use of a chiral center bound to the reactive center through a covalent bond and remains so during the reaction. The starting material is often derived from chiral pool synthesis. In relayed asymmetric induction the chiral information is introduced in a separate step and removed again in a separate chemical reaction. Special synthons are called chiral auxiliaries. In external asymmetric induction chiral information is introduced in the transition state through a catalyst of chiral ligand. This method of asymmetric synthesis is economically most desirable.

...absolutely proven. Inductive reasoning is not without worth because it leads humanity to many understandings. As Appiah said, “If we use induction with a predicate that is reliable, we are using a belief-forming process, and so according to reliabilism, we are acquiring knowledge.” (Appiah 163). This shows that inductive reasoning is not insignificant and that our hypotheses based on it are, to some extent, dependable.
While on the one hand, Hume would argue that inductive reasoning cannot be justified and on the other Appiah would argue that inductive reasoning is plausible, many people would fit somewhere in between these two theories. One such theory in between the two polar arguments has been brought by Nelson Goodman. His belief is that inductive reasoning is sometimes credible, yet sometimes not credible. As Appiah stated about Goodman, “Goodman’s own suggestion for dealing with the new riddle of induction is that we should rely on enumerative induction in certain cases, cases where the predicates involved” (Appiah 162). Though, even this argument shows difficulty in being justified. For, if we use predicates from the past, we would believe that because it had worked out in the past then it would work out in the future. However, Goodman holds another important point. He would argue that not each generalization due to induction would be able to be justified by particular instances, which is...

Keeping the language common among manufacturers is critical to making motors interchangeable
The U.S. motor industry has worked on a standardized basis for more than three-quarters of a century. The standardization agency — National Electrical Manufacturers Association (NEMA) — was established in 1926 “… to promote the standardization of electrical apparatus and supplies.” As a result of this group's efforts, you can expect “standard” motors from different manufacturers to meet or exceed minimum performance parameters and, for the most part, be about the same size.
A critical part of making motors interchangeable is ensuring that nameplate information is common among manufacturers. The common language of the motor nameplate enables installation and maintenance personnel to quickly understand and...

A HIGH PERFORMANCE INDUCTION MOTOR DRIVE SYSTEM USING FUZZY LOGIC CONTROLLER
ABSTRACT
Abstract- Basically, the motor drive system comprises a voltage source inverter-fed induction motor (VSIM): namely a three-phase voltage source inverter and the induction motor. The squirrel-cage induction motor voltage equations are based on an orthogonal d-q reference-rotating frame where the coordinates rotate with the controlled source frequency. The paper presents a novel fuzzy logic controller for high performance induction motor drive system. The inputs to the fuzzy logic controller are the linguistic variables of speed error and change of speed error, while the output is change in switching control frequency of the voltage source inverter. In this paper a comparison between fuzzy logic controller and traditional PI controllers are presented. The results validate the robustness and effectiveness of the proposed fuzzy logic controller for high performance of induction motor drive. Simulink software that comes along with MATLAB was used to simulate the proposed model.

Set in Soft Set:
A Topological Approach
Tutut Herawan, Universiti Malaysia Pahang, Malaysia
ABSTRACT
In this paper, the author presents the concept of topological space that must be used to show a relation between rough set and soft set. There are two main results presented; firstly, a construction of a quasi-discrete
topology using indiscernibility (equivalence) relation in rough set theory is described. Secondly, the paper
describes that a “general” topology is a special case of soft set. Hence, it is concluded that every rough set
can be considered as a soft set.

1. INTRODUCTION
The problem of imprecise knowledge has been
tackled for a long time by mathematicians. Recently it became also a crucial issue for computer
scientists, particularly in the area of artificial
intelligence. There are many approaches to the
problem of how to understand and manipulate
imprecise knowledge. The most successful one
is, no doubt, the fuzzy set theory proposed by
Zadeh (1965). The basic tools of the theory are
possibility measures. There is extensive literature on fuzzy logic with also discusses some of
the problem with this theory. The basic problem
of fuzzy set theory is the...
