This chapter presents a literature reappraisal on major constituents of this research every bit good as related subject. The reappraisal will be briefly on instruction in Malaysia, mathematics subject in lower secondary degree and besides on pupils ‘ degree of public presentation in simplification of algebraic look. From the reappraisal, it will take to decision that will associate the constituents of the subjects to do it clearer as a bigger image and to emphasize the importance of carry oning this research.

These purposes of research are to look into the pupils ‘ degree of public presentation in simplification of algebraic look among form four pupils at Sekolah Menengah Teknik Shah Alam, Selangor. Besides that, this research will be conducted to place the common mistakes that were made by the pupils in the trial of algebraic look simplification. In add-on, the research besides wants to see the relationship of pupils ‘ public presentation among gender, their PMR scrutiny class and the classs of trial in algebraic look simplification.

## 2.1 Mathematicss Concepts

It is true hard to find the degree of understanding or command of a certain construct. So is the instance in this instance survey which involves the degree of command of basic constructs of Mathematicss for the simplification subtopic in the subject of Algebraic Expression. However, it can be evaluated by looking at the construct of apprehension and common errors made by pupils in work outing Mathematical jobs.

Based on the construct of comprehension, pupils must understand the construct of Mathematics, which is following the stairss right in work outing Mathematical jobs. Rubric should be the footing for the resolution of Mathematics ( Skemp, 1971 ). The construct of apprehension is wholly different than cognition. Understanding is an ability to use while looking for ways to accomplish the targeted ends. Skemps besides differentiates between 3 types of apprehension, viz. instrumental, understanding of relationship and logical apprehension.

Based on Skemp ‘s statement, it can be observed that in work outing Mathematical jobs, it requires the right stairss. This can be related to the working which is undeniably the most of import thing in work outing Mathematical-related jobs. The right and systematic working can decidedly supply the accurate reply or solution as what the inquiry requires.

Most Mathematical psychologists agree that the construct of Mathematics is difficult to specify ( Skemp, 1971 ). Mathematical constructs can be divided to primary and secondary constructs. The primary construct is formed utilizing senses and the initiation method, which is to abstract through observation of similar characteristics.

What is needed is the beginnings of conceptual and proficient cognition related every bit good as tehnical support in understanding the work outing procedure. ( Schoenfeld,1985 ). Students were found to utilize incorrect construct of solve due to mistakes in understanding a certain construct. Understanding Mathematics requires constructing a clear basic construct and anticipation of a certain construct being made easy should it be done hierarchically.

Cognitive psychologist are of the sentiment that there exists differences between conceptual cognition and procedural cognition, and yet both have critical and reciprocally good relationship. Solid conceptual cognition will further acquisition, cut down use of confounding processs, doing them to retrieve the appropriate processs to be used and bettering the quality of executing a certain problem-solving.

A theoretical account of solution affecting 4 stages, viz. understanding job, plannin solution, making solution and look intoing the replies produced is being proposed ( Polya, 1957 ). The first stage requires pupils to read, understand and make up one’s mind what is required of the inquiry. The 2nd stage requires the relation between fact and the informations therefore be aftering for stairss to work out. Students conduct work outing by making computation and eventually look intoing the replies produced to guarantee that the inquiry is solved right along with the reply.

Hiebert ( 1997 ) said that pupils need to get the hang certain constructs in Mathematics where indoors contain regulations, processs and rules of simple Mathematicss. They besides need to larn on how to utilize those processs and rules to enable them to work out the Mathematical jobs. However, pupils who managed to accomplish high consequence in Mathematics still failed to utilize the cognition and accomplishments of Mathematics into other state of affairss or topics. ( Schoenfeld, 1985 ). This shows that the apprehension of constructs is really critical to accomplish first-class consequence in true significance.

## 2.2 Students ‘ Performance in Mathematicss

In mathematics capable, the public presentation or accomplishment is of import to mensurate pupils ‘ apprehension towards the constructs of mathematics. In add-on, mathematics is the of import topic because the good class of mathematics capable is the green visible radiation for the pupils particularly in Malaysia to prosecute their survey in local or international university. Therefore, the pupils must obtained a good consequence in mathematics in order to acquire a good university and class in university system. Harmonizing to Piaget, ( 1970 ), young person who is good in Mathematicss develop his get downing perceptual experiences of and actions in environment, believing about them, and ensuing in the public presentation of new actions upon the mental and/ or physical objects. Harmonizing to Chan ( 1999 ) in his research on the vocational watercourse pupils found out that the degree of cognition and apprehension of pupils on algebraic subject was at a low degree and this caused misconceptions among the pupils. Due to the misconception among the pupils ‘ public presentation and accomplishment for the algebraic subject, dwindling demand to be improved to avoid large errors for algebraic related subjects.

## 2.3 Students ‘ Performance in Mathematics among Gender

The research worker wants to look into the pupils ‘ public presentation in mathematics particularly in simplification of algebraic look among male and female. There are a batch of researches that measure about pupils ‘ ability, public presentation, attitudes dan accomplishment among gender. In between this gender, there are many things different, such as the cognitive thought, personality and psycological thought. In this research, the research worker investigate between pupils public presentation in trial of algebraic look simplification. Harmonizing to Mondoh and Changeiywo, ( 2000 ) stated that the different acquisition manners between misss and male childs and the likely consequence of these on cognitive and scrutiny accomplishment, peculiarly in mathematics.

Harmonizing to Fierros, 1999 ; Zhang & A ; Manon, 2000 ; Johnson, 2000 ; Leahe & A ; Guo, 2001 ; Erickan et. Al. 2005, showed that no important difference in accomplishment between male childs and misss as they start acquiring acquainted with mathematics. The researches were supported with the survey by Lee and Lockheed, ( 1990 ) found that no important gender spread between mathematics mark of Nigerian male childs and misss one time other variables were taken into history. From the old surveies by Gallagher and Kaufman, ( 2005 ) and Cleary, ( 1992 ) found that females by and large scored lower than males on standardised trial of mathematics. It is because male normally spend their clip with making the exercisings about algebra, and quadratic equation in their free clip compared to the female pupils.

However, their determination was opposed with Halimah and Noor Azina ( n.d ) that their paper is about Gender differences in mathematics larning in Malaysia. Their purpose of survey is to analyze gender derived functions in footings of the overall mathematics mean accomplishment every bit good as the chief content country of mathematics subjects and accomplishments, viz. fraction and figure sense ; informations representation, analysis and chance ; geometry and algebra. From their determination was wholly different from international researches among gender in mathematics accomplishment which is the female obtained better accomplishment compared to male in three countries of mathematics contents viz., figure, algebra and informations.

## 2.4 The Relationship between the Performance in Test of Algebraic Expression Simplification and Mathematic PMR Examination Grade.

With the good consequence in Mathematics PMR scrutiny is non necesarily the pupils have a good constructs in mathematics. Therefore, the research worker wants to look into the relationship of pupils ‘ public presentation in TAES between mathematic PMR scrutiny in this research. Harmonizing to Wong study, ( 1987 ) stated that the pupils ‘ failings in mathematics can do them troubles to maestro in few chapters in signifier 4 and 5 course of studies in modern mathematics or extra mathematics. Therefore, the good BASIC constructs play the of import functions for the pupils to understand better in algebraic look subject. During the mathematics PMR paper, the inquiries normally contains really simple inquiry in order to assist the pupils to derive good consequence but the pupils can memorise the stairss and processs when answer the inquiries.

## 2.5 Students ‘ Common Mistakes in Test of Algebraic Expression Simplification

Previous researches found many findings related to errors and apprehension of pupils in work outing Mathematical jobs that can be referred to in carry oning this instance survey. Generally, errors are frequently defined as perpetrating a misconduct accidentally and understanding is a procedure to understand a certain construct.

Based on old researches, subjects in Mathematics those pupils frequently commit errors are:

## ( 1 ) Algebraic Expression

Saripah Latipah ( 2000 ) found that pupils did non get the hang the basic constructs of Algebraic Expression good and this caused misconception to happen in the basic operation of Algebra. Students were found to perpetrate error in Algebraic Expression in footings of certain facets such as simplifying fraction, algebra, factorize and enlargement of two looks ( Rosli, 2000 ).

## ( 2 ) Fraction

Research has found that the errors that pupils frequently commit in the fraction subject is non simplifying fraction into proper fraction. Besides that, pupils besides made errors in the add-on operation of fraction ( Maznah Mahmood, 2000 ).

## ( 3 ) Negative Integer

Students have misconception on the subject of Negative Integer while making basic operation such as add-on and minus of figure ( Khamsan, 1999 ). Haslina ( 1999 ) in her survey mentioned that particularly on Negative Integer, there are misconceptions in the subject of whole number. The misconception covers all four accomplishment processes, viz. add-on, minus, generation and division.

There are five classs of pupils ‘ errors while replying the Mathematics inquiries ( Newman, 1977 ). The errors are mistake in reading, misidentify in understanding inquiry, error in showing, error in processing and error in saying reply are common errors that happen among the pupils.

The active to chair groups are those who frequently commit sloppiness. This is normally due to them hotfooting and presuming the inquiry to be excessively easy. This carelessness error is normally committed by the pupils themselves and affect a few factors. Among others is desiring to reply the inquiry excessively fast, presuming the inquiries to be excessively easy and deficiency of clip in replying.

Three forms of errors have been identified ( Cox, 1974 ). The errors are systematic error, random error and carelessness error. In this instance, systematic is based or harmonizing to system. Therefore, the systematic error happens when pupils try to work out the job harmonizing to the stairss but made a few errors. This is normally little error made unconsciously by the pupils. Random error on the other manus happens due to unsystematic working that normally happens to pupils. This error happens due to pupils making working unsystematically and causes mistake to easy happen. Meanwhile, carelessness error is a error that is difficult to rectify. It can merely be done by the pupils themselves by replying carefully and apportioning equal sum of clip on a inquiry so as non to hotfoot through.

It is found that all pupils experience trouble in Mathematics ( Ress and Barr,1984 ) and the degree of trouble depends on the age and the ability of the pupils themselves. The signifiers of errors are due to misconception, command of algorithm accomplishments and condemning job.

Mistakes in larning Mathematicss can be traced farther to certain procedures where the accomplishment needs to be mastered foremost and non merely from the correct reply ( Radetz and Yap,1982 ). This refers to the working that is frequently related to in the resolution of Mathematical inquiries.

Intensive drills and the ability to do justification on selecting of certain working to work out jobs are among the ways that Dossey et. Al. ( 2002 ) recommended bettering their apprehension in work outing mathematical inquiries. Continuous exercisings will assist pupils to understand a certain construct or method available in the Mathematics topics. Apart from that, pupils can cut down the errors in trying a certain mathematical inquiry and accordingly lead to better apprehension of the constructs of mathematics.

## 2.6 Drumhead

This chapter has discussed on pupils ‘ public presentation in mathematics, public presentation among gender, relationship of public presentation in TAES and Mathematics PMR scrutiny class and the pupils ‘ common mistakes in algebraic look simplification. Through this chapter, research worker wants to roll up grounds from old research on subject selected by research worker in finishing this research. Researcher refers a batch to old research in happening the difference in old findings and from research worker ‘s ain mention.
