1 TIMSS 2011 The TIMSS 2011 Students Like Learning Science Scale, Eighth Grade The Students Like Learning Science (SLS) scale was created based on students degree of agreement to the five statements described below. See Creating and Interpreting TIMSS and PIRLS 2011 Context Questionnaire Scales for more information on how the scales were formed. Exhibit 1: Items in the TIMSS 2011 Students Like Learning Science Scale, Eighth Grade How much do you agree with these statements about learning science? Agree Agree Disagree Disagree a lot a little a little a lot BSBS17A BSBS17B* BSBS17D* BSBS17E BSBS17F 1) I enjoy learning science A A A A 2) I wish I did not have to study science* A A A A 3) Science is boring* A A A A 4) I learn many interesting things in science A A A A 5) I like science A A A A * Reverse coded Like Somewhat Like Do Not Like
