This study aimed at investigating the effect of three task variables:additional  unnesessary  information (without additional unnesessary  information , with additional  unnesessary information) , tendency of  representation of  problems  ( tendency  of  representation  of  problems , untendency of  representation of  problems) , nature  of  the  problems  ( concrete , abstract ) ,  in  the  ability  of 10th basic  grade  students to solve the static  electrisity  and  the effects  of  electric current  thermally  and chemically problems . Another  purpose  of  this study  was to  investigate  the effects of  the following personal variables : gender , justifical ability ,reading ability , and analatical ability , in the  ability  of  students to  solve  verbally  physically   problems.
The  sample  consisted of ( 280 )  10th  basic grade Students Jenin Schools , distributed  over (12) sections , ( ( 7 ) for male, and ( 5) for female) . Atest was developed by the researcher , consisted of two forms : A ( without   additional   unnesessary   information with tendency/untendency of  representation of  problems and concrete  nature /abstract problems ),  B  (  with   additional   unnesessary  information   with    tendency  /  untendency   of   representation of  the  problems  and  concrete /abstract  nature ) . ( 50%  ) of  every  section  were randomly given one of the two forms .
The  three-way  analysis of variance with  factor design ( 2*2*2 )  was  used  to  answer  the  first  seven questions  in  this  study  ,  and  factor  design  ( 3*3*3 ) was  used  to  answer  the  last  seven  questions  in this  study , and  a “ T” test was used  to  test  the  8th    hypothesis . “T” test  and  scheffe test to test the  significant differences . The results of the analysis were as follows :
- There were  statistical significant differences  in  the ability of the students to  solve  verbal physical  problems  due  to  the  additional  unnesessary  information ,  favour  of  problems  without additional unnesessary information.
- There were statistical significant differences  in  the ability of  the students  to  solve verbal physical  problems due to the tendency of  representation  of  problems , in  favour  of problems  have tendency of representation of problems.
- There were statistical significant differences in the ability of  the students  to  solve  verbal  physical  problems due to the nature of  the problems in favour  of  problems of  concrete nature.
- There were no statistical significant differences in the ability of the students to solve verbal  physical  problems due to  the   two-way   interaction  and  three-way  interaction between  the  three  structural task variables of  verbal problems .
There were no statistical significant differences in the ability of the students to solve verbal  physical problems due to the gender of the students .
- There were statistical significant differences in the ability of  the students  to  solve  verbal  physical problems due to the justifical ability level , in favour of high  justifical ability level.
- There were statistical significant differences in  the ability of  the students  to  solve verbal  physical problems due to the reading ability  level , in favour of  high reading ability level.
- There were statistical significant differences  in  the  ability  of  the  students to solve verbal physical problems due to the proplem analatical ability level , in favour of  high  analatical ability level.
- There were statistical significant differences  in the ability of  the  students  to solve  verbal  physical problems due to  the two-way interaction and  three - way interaction between   the   three variables:  justifical ability level , reading ability level , and problem analytical ability level.
In  the light of  study  results ,  the  Researcher  recommend  that  curricula  designers  ,  teachers  and suprvisors and those who are in charge of educational training and qualifying to take into account  the constructive variables when stating the verbal physical problems .The Researcher also recomends that other researchers to do more studies on there topics elated to the present study.
