Preferred Abstract (Original):

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.
