         INTRODUCTION

              The factors influencing academic achievement has been  a

         much  researched  area  and  one  of  the dominant factors in

         Malaysian schools is the  socio-economic  background  of  the

         learner.  In  a recent study it was shown that socio-eocnomic

         factors played an  important  role  in  influencing  academic

         achievement  in  the  primary  grades  and  its influence was

         relatively less among secondary school  students  (Leong  et.

         al,  1992).  The main focus of this study is to determine the

         extent to which the cognitive abilities  of  learners,  which

         has  been  operationally defined to include spatial aptitude,

         deductive  reasoning,  analogical  reasoning  and  mechanical

         comprehension;  influences  their  performance in the various

         school subjects. 

              Lohman  (1979) in a review of studies on spatial ability

         identified two  main  aspects  of  spatial  ability,  namely;

         spatial   orientation  and  spatial  visualisation.   Spatial

         orientation involves the  ability  to  imagine  how  a  given

         object  or  set  of  objects  would  appear  from  a  spatial

         perspective different from that  in  which  the  objects  are

         shown.  Usually,  spatial-orientation tasks require people to

         reorient themselves relative to  the  object  or  objects  in

         question.   Spatial  visualisation  requires  complex  mental

         rotation of one or more  visualised  objects  such  as  those

         involved  in  mental paper folding or mental rearrangement of

         pieces of an object to form the whole object. 

              Guay  and  McDanial(1977)  found that spatial ability of

         school children was significantly correlated with achievement

         in mathematics.  Lam (1989) found similar evidence  among  16

         year old Malaysian students but it was confined to a selected

         aspect  of  spatial  ability  based  on the Punch Holes Test. 

         More specifically,  Fennema and Sherman (1977) showed that it

         was  spatial  visualisation that was more importantly related

         to  mathematics  achievement.  Besides  mathematics,  spatial

         ability  was  found  to  be strongly linked to achievement in

         science (Tracy,  1987),  and  statistics  (Elmore  and  Vasu,

         1980). 

              Gender  differences  in   spatial   ability   has   been

         extensively  investigated.  Studies  by  Johnson  and  Meade,

         (1987)  and Wittig and Peterson (1979) showed that males have

         better spatial ability  than  females  beginning  from  early

         adolescence and continuing through adulthood.  Wong (1992) in

         a study of 16 year old Malaysians  found  that  males  scored

         significantly higher in spatial ability than females.  Gender

         was   the  best  single  predictor  of  spatial  ability  and

         accounted for about a third of total  variance.  Also,  there

         was   evidence   to   indicate   that   students   from  high

         socioeconomic  background  were  better  in  spatial  ability

         compared   to   their  school-mates  from  low  socioeconomic

         families. 

              It has been suggested that reasoning occupies a  central

         position  in explaining intellectual abilities (Rips,  1984). 

         Two  types  of  reasoning  have  been  identified,   that  is

         deductive reasoning and inductive reasoning. 

              Deductive  reasoning  has  been defined as an attempt by

         the learner to integrate elements of the old  information  in

         the construction of new information (Sternberg, 1982).  It is

         reasoning  based  on  a  given  premise that is sufficient to

         reach a valid conclusion.  A number  of  different  kinds  of

         deductive reasoning problems have been studied.  For example,

         mathematical  word  problems,  propositional  reasoning,  and

         syllogistic   reasoning   all   involve   primary  deductive

         inference.  Shaver  and  his  associates  (1974)  found  that

         performance on deductive reasoning tasks was highly correlated

         with  performance  on verbal,  spatial and abstract reasoning

         ability tests. In a review of research on deductive reasoning

         among adults,  Sternberg (1982) observed that subjects differ

         in  the  strategies they use to solve linear syllogisms.  The

         large majority of subjects used  a  mixed  spatial-linguistic

         strategy  while  a  small  number  use  either  a  spatial or

         linguistic model. 

              In  inductive reasoning the information contained in the

         premises of a problem is insufficient to reach a  conclusion. 

         A  number  of different kinds of inductive reasoning problems

         have been  studied  and  the  most  common  being  analogical

         reasoning.  An  analogy is a problem of the form A is to B as

         C is to D (A:B:  :C:D),  where,  in most instances,  the last

         term is omitted and must be filled in, selected from among a

         number  of  options.  Analogies  can be presented in any of a

         number  of  different  kinds  of  content,  such  as  verbal,

         geometric  or  schematic-picture.  In an early study,  Lunzer

         (1965) presented students between  9-17  years  of  age  with

         verbal analogies and found that children had great difficulty

         with  even  the  simplest analogies until about nine years of

         age, and did not show highly successful performance until the

         age of 11.  Whitely (1977) showed that  analogical  reasoning

         was  closely  related to scores obtained on standard measures

         of  mental  ability.  Phillips  (in press) found that 13 year

         old students in a Malaysian  school  who  performed  well  on

         analogical reasoning tests were also high academic achievers. 

         Hesse (1966)  reiterated  the role of analogical reasoning in

         scientific thinking. 

              Mechanical  comprehension  requires  the  respondent  to

         apply  simple  principles  of  physics   and   mechanics   in

         responding  to  questions concerning the operations of common

         machines,  tools,  and vehicles.  The subject is required  to

         predict the outcome of mechanical activities,  or  to  reason

         backwards  from effects to probable mechanical causes (Murphy

         and Davidshofer, 1991).  Studies by Ghiselli (1966) has shown

         moderate correlations with performance  in  training  courses

         and  job  performance  of  machinists,  mechanics and machine

         operators. 

              Specifically,  the  study  sought  to  find  answers  to 

         the following questions:

              1. To what extent is academic achievement related to the

                 cognitive abilities (i.e. spatial aptitude, deductive

                 thinking, analogical reasoning and mechanical

                 comprehension) of secondary school students? 

              2. Does   the   socioeconomic   background  of  students

                 influence their cognitive abilities? 

              3. Is there a difference in cognitive abilities between

                 male and female students? 

 

         METHOD

         a. Subjects

              The sample of 106 Form One students were  selected  from

         one  secondary  school  in  the  Federal  Territory  of Kuala

         Lumpur.  The subjects, between the ages of 12-13 years of age

         were selected from three intact classes of high,  average and

         low academic ability students as streamed by the school based

         on their UPSR scores. There were 44 males and 62 females. 

 

         b.  Instrumentation 

              An  instrument  called  the  Cognitive   Ability   Test,

         consisting  of  84 items was adapted and developed consisting

         of 6 subtests (see Table  1).  The  mechanical  comprehension

         subtest and parts of the spatial ability subtest were adapted

         from   the  Differential  Aptitude  Test  (DAT)  by  Bennett,

         Seashore  and  Wesman  (1963).   Parts  of   the   analogical

         reasoning   subtest   was  adapted  from  Test  Your  Child's

         Reasoning Ability,  Booklet I &  II,  by  Headway,  Hodder  &

         Stoughton  Ltd.  Kent (1988).  The other items were developed

         by the researcher. 

              The  instrument  was  pilot-tested  with  a  group of 75

         randomly selected Form One students wherein respondents  were

         encouraged to comment on the items.  Respondents commented on

         the items especially with regards to clarity of instructions,

         the  difficulty  of  understanding  the  items and clarity of

         presentation  of   the   figure   items.   Based   on   their

         suggestions,   relevant   modifications   were  made  to  the

         instrument.  To obtain an indication of  the  reliability  of

         the  CAT,  a odd-even split half reliability test was carried

         out and  the  coefficients  are  reported  in  Table  1.  The

         reliability  coefficient  for  the  CAT  is 0.85 which may be

         regarded  as  high.  The  reliability  coefficients  for  the

         individual subtests reveal wide variation.  For example,  the

         reliability coefficient for the Spatial  Orientation  subtest

         was  0.69  compared  to 0.41 for the Mechanical Comprehension

         subtest.  However, all reliability coefficients obtained were

         significant at p = < 0.01.

         c. Operational Definition

              Academic achievement was determined  by  performance  in

         selected subjects at the primary and secondary school levels. 

         Based  on  the  Primary  School Evaluation Test (UPSR) grades

         were obtained for Bahasa Melayu, Mathematics and English.  To

         obtain a composite score,  points were assigned wherein grade

         A was assigned 5 points, grade B was assigned 4 points, grade

         C  was  assigned 3 points,  grade D was assigned 2 points and

         grade E was assigned 1 point.  For  academic  achievement  at

         the  secondary school level,  class test scores were obtained

         for   seven   subjects   namely   Bahasa   Melayu,   English,

         Mathematics,  Science,  History, Geography and Living Skills,

         and a total composite score was computed. 

 

         RESULTS

         a. Cognitive Abilities  and Academic Achievement 

              Based on the composite score of performance in the UPSR,

         subjects were divided into  high  and  low  academic  ability

         using   the   mean  as  the  cut-off  point  (see  Table  2). 

         Generally,  high ability students (M = 60.3) outperformed low

         ability  students  (M  = 50.8) on total cognitive ability and

         the difference was significant at p = <  .001.  However,  the

         performance  of  subjects on the CAT was low considering that

         the total score possible is 84.

              Students  were  also grouped according to ability levels

         based on performance in class tests at the  secondary  school

         level.  Using the mean as a cut-off point (M = 407), students

         were  divided  into high and low ability.  The performance of

         high academic ability students on total cognitive ability was

         higher (M = 61.2) than low academic  ability  students  (M  =

         49.8).  This  difference was statistically significant at p =

         < 0.001.

            Table 3: Correlation Coefficients between School Subjects

              Further the relationship  between  academic  achievement

         and  the  individual  subtests  of  the CAT was computed (see

         Table 3).  The correlation between  total  cognitive  ability

         and  overall  performance  on  class  tests  at the secondary

         school level was 0.62 and in terms  of  individual  cognitive

         abilities,  the correlation was especially high for deduction

         (0.53).  The  correlation between total cognitive ability and

         performance in the UPSR was 0.55 with none  of  the  subtests

         being more highly correlated with academic achievement. 

              A breakdown by subject areas  at  the  secondary  school

         level  revealed  that  English  (0.60),  Science  (0.59)  and

         Mathematics (0.56) correlated  highly  with  total  cognitive

         ability  compared  to  the  other  subject areas.  The lowest

         coefficient of correlation was  reported  for  Living  Skills

         (0.37). 

              In   terms  of  specific  cognitive  abilities  and  the

         individual subject areas, deductive reasoning was reported to

         be more highly correlated with performance in Science  (0.51)

         and  English  (0.50)  compared  to  the  other subjects.  The

         correlation  between  mathematics  and  spatial   orientation

         (0.36)  and  spatial visualisation (0.43) was relatively low. 

         However,   among   the   seven   school   subjects,   spatial

         visualisation and spatial orientation correlated highest with

         mathematics and lowest with Living Skills.  Surprisingly, the

         correlation   between   spatial  ability  and  geography  was

         relatively low.  Also,  there  was  almost  zero  correlation

         between  mechanical  comprehension  (0.07) and performance in

         Living Skills.

                       the Cognitive Ability Test as the Dependent

                       Variable

 

 

              The data was subject to a step-wise regression  analysis

         (see  Table  4).  The  three  variables entered were academic

         achievement score, gender and socioeconomic status with total

         cognitive ability as the dependent variable.  The multiple  R

         obtained  was  0.638  and  the  R square was 0.407.  In other

         words,   40.7%  of  the  variance  was  contributed  by   the

         combination  of  the  three variables entered in the equation

         while the remaining variance was unaccounted for.  Among  the

         three   variables   entered,   39.4%   of  the  variance  was

         contributed  by  academic  achievement   while   gender   and

         socioeconomic  contributed  only  minimally (1.3%).  In other

         words,  academic achievement is the best single predictor  of

         the selected cognitive abilities studied. 

 

         b. Socioeconomic  Background  and Cognitive Ability

              Based on the occupation of the  father  and  mother  (if

         any)  of  the  students,  the  sample  was classified as high

         socio-economic status (HSES) and  low  socio-economic  status

         (LSES).  For example,  the student who stated that his or her

         father was a security guard or  labourer  was  classified  as

         LSES  while  a  student  whose  father  is  an  executive  or

         professional was classified as HSES.

              Overall,  students  from  high  socioeconomic background

         scored higher (M=59.1) than students from  low  socioeconomic

         background  (M=53.6) on the Cognitive Ability Test (see Table

         5).  The difference  was  significant  at  p  =  <.05  level. 

         Consistently,  HSES students scored higher than LSES students

         on  all  the  six   subtests.   But,   the   difference   was

         statistically   significant   only   for   verbal  analogical

         respectively)  than  students   from   poorer   socioeconomic

         background (M=9.4 and M=8.6 respectively). 

 

         c. Gender and Cognitive Ability

              Data  was  also  analysed according to gender (see Table

         6).   Overall  there  were  no  significant  differences   in

         cognitive  ability  between  male  and  female  students even

         though the males scored slightly higher (M=56.7) than females

         (M=55.2).  However,  performance on the individual  subtests,

         revealed  that  male  students  (M=10.72)  scored higher than

         female  students  (M=9.64)  on  spatial  visualisation.  This

         difference  was  significant  at  p = <.05 level.  Males also

         scored slightly higher than females in both verbal and figure

         analogical reasoning as well as mechanical comprehension, but

         the difference was not significant.  Female subjects,  on the

         other   hand   scored   slightly   higher   than  their  male

         counterparts in spatial orientation and  deduction,  but  the

         difference was too small to be significant.

         DISCUSSION

              The relationship of academic ability to  differences  in

         cognitive  abilities  measured  is significant.  Consistently,

         high ability learners,  whether based on primary or secondary

         test scores,  significantly outperformed low ability learners

         on total cognitive ability.  According  to  school  subjects,

         interestingly  performance  in  English  and  Science is more

         related to the selected cognitive abilities  of  students  as

         reflected  in  the relatively high coefficients reported.  It

         is probable that in  these  two  school  subjects,  cognitive

         skills  such  as  deductive thinking and analogical reasoning

         are encouraged. 

              Surprisingly, the mechanical comprehension subtest was a

         poor  predictor  of  performance in the subject Living Skills

         though it teaches technical elements  such  as  understanding

         and  repairing  of  household  appliances.   However,  Living

         Skills also includes non-technical aspects such  as  commerce

         which  may not be related to mechanical reasoning.  The study

         found that among the school  subjects,  mathematics  reported

         the   highest  correlation  with  spatial  ability  which  is

         consistent with the findings of Guay &  McDanial  (1977)  and

         Wong   (1992).   Overall,   academic   achievement   plays  a

         significant role in influencing the  cognitive  abilities  of

         students in the sample studied. 

              The  higher  cognitive  abilities  of students from high

         income families suggest that such  abilities  may  be  better

         nurtured  in  these  families. Greater  opportunities for the

         development of such skill may have been  made  available  for

         learners   from  such  advantaged  families  through  reading

         materials,  thought  challenging  games  and  activities  and

         perhaps   a   generally   more   conducive  environment  that

         encourages such types of thinking. 

              In  terms  of  gender,  males  outperformed  females  in

         spatial visualisation.  This finding is partially  consistent

         with  earlier studies wherein females scored lower in spatial

         ability than their male counterparts.  Wong (1992) found that

         males performed better than females in spatial  visualisation

         and  spatial  orientation.  The  present  study  found gender

         differences  was  only  for  spatial visualisation.  In fact,

         females scored  higher  in  spatial  orientation  than  males

         though  the difference was not significant. 

              Generally, this study reveals that there is evidence for

         individual  differences  in   cognitive   abilities   between

         students  in  the  sample  and  suggests  that  the Cognitive

         Ability Test be administered to a  larger  sample  to  detect

         developmental differences and the establishment of norms.
