All details of the file structure are provided in codebook files related to each of the data files listed in Table 7.1. The use of these codebooks is described in Section 7.3.

C H A P T E R 7 D A T A B A S E F I L E S 7.2.1 Background Files There are three different types of TIMSS background files – student, teacher, and school. 7.2.1.1 Student Background File Students who participated in TIMSS were administered a background questionnaire with questions related to home background and school experiences. The Student Background file contains students' responses to these questions. One version of the questionnaire was administered in Population 1 and two versions were administered in Population 2. In Population 2, one version was tailored for educational systems where science is taught as an integrated subject (non-specialized version). The second version was tailored for educational systems where the sciences (biology, earth science, physics, and chemistry) are taught separately (specialized version). Table 2.8 in Chapter 2 shows which countries administered the specialized and nonspecialized versions of the questionnaire. Although most countries chose to use one version of the questionnaire, some countries opted to use both. The variable ITQUEST identifies the version of the questionnaire that was administered to the students in Population 2. For students who were administered the non-specialized version, all questions that were given only in the specialized version were coded as not administered. For students who were assigned a specialized version of the questionnaire, all questions that were asked only in the non-specialized version were coded as not administered. The Student Background files also contain a series of identification variables, link variables, sampling variables, achievement variables, and the derived variables that were used for the creation of the international reports. 7.2.1.2 Teacher Background File The mathematics and science teachers of the students who were sampled for TIMSS were administered at least one questionnaire with questions pertaining to their background and their teaching practices in the classes of the sampled students. Each teacher was asked to respond to a questionnaire for each class taught that contained sampled students. The Teacher Background files contain one record for each of the classes taught by either a mathematics or a science teacher. In some cases, although the teacher was to respond to more than one questionnaire, responses to only one were obtained. In these cases, there were as many records entered in the teacher file as classes were taught by the teacher, and the background information from the complete questionnaire was entered into these teacher records. In Population 1 a single questionnaire was administered since both mathematics and science are usually taught by the same teacher at this age level; the responses to this questionnaire can be found in one file. There were two questionnaires administered in Population 2 – one for the mathematics teachers and one for the science teachers. The data from these questionnaires are found in separate files. Variable names for questions asked in both questionnaires are the same. In the Teacher Background data files each teacher was assigned a unique identification number (IDTEACH) and a Teacher Link Number (IDLINK) that is specific to the class taught by the teacher and to which the information in the data record corresponds. The IDTEACH and IDLINK combination uniquely identifies a teacher teaching one specific class. So, for example, students linked to teachers identified by the same IDTEACH but different IDLINK are taught by the same teacher but in different classes. The Teacher Background files cannot be merged directly onto the 7 - 4 T I M S S D A T A B A S E U S E R G U I D E
