Trends in International Mathematics and Science Study (TIMSS) 2015 Grade 9: Science teacher (BTS) - South Africa as one of 39 countries

Description:
This data set contains science teacher responses to the teacher background questionnaire, i.e. school emphasis on academic success, school environment, about being a teacher, about teaching the TIMSS class, etc. All science teachers were required to complete this questionnaire.

The data set has 215 variables and was completed by 331 teachers.

Of the 300 sampled schools, 292 schools was realised providing a response rate of 97%.
Abstract:
TIMSS is a cross-national assessment of mathematics and science knowledge of fourth and eighth grades and includes 53 countries. The Grade 9 mathematics and science assessment included 39 countries. It is conducted by the International Association for the Evaluation of Educational Achievement (IEA) every four years since 1995. South Africa took part in five cycles of TIMSS i.e. in 1995, 1999, 2003, 2011 and 2015 with fieldwork being conducted in August/September 2015.

The Human Sciences Research Council (HSRC) administered the study in 292 schools and assessed 12514 learners across South Africa. To prevent a cluster of scores at the lower end of the scale and to ensure sufficient variance in the data for robust analyses; TIMSS was administered to grade 9 learners in South Africa. As part of the TIMSS study mathematics and science tests and background questionnaires are administered to an intact randomly selected grade 9 class within a sampled school.

TIMSS uses the results from the tests and questionnaires which are administered to learners, teachers and principals to determine the achievement scores as well as the factors associated with academic success. One of the main aims of the study is to measure the health of the education systems for a particular country.

This data set contains science teacher responses to the teacher background questionnaire, i.e. school emphasis on academic success, school environment, about being a teacher, about teaching the TIMSS class, etc. All science teachers were required to complete this questionnaire.

数据集说明：
本数据集包含理科教师对教师背景调查问卷的作答数据，涵盖学校对学业成就的重视程度、学校环境、从教情况、TIMSS班级教学相关情况等内容。所有理科教师均需完成该调查问卷。

本数据集共包含215个变量，共有331名教师完成作答。

在抽取的300所学校中，最终有292所学校参与调研，有效应答率为97%。
摘要：
TIMSS（国际数学与科学趋势研究）是一项针对四年级和八年级学生数学与科学知识的跨国评估项目，共有53个国家参与。九年级数学与科学评估项目则有39个国家参与。该项目自1995年起，每四年由国际教育成就评价协会（International Association for the Evaluation of Educational Achievement, IEA）举办一次。南非共参与了五轮TIMSS调研，分别为1995年、1999年、2003年、2011年及2015年，2015年的实地调研于当年8月/9月开展。

南非人类科学研究理事会（Human Sciences Research Council, HSRC）在292所学校中实施了本次调研，并对南非全国范围内的12514名学生进行了评估。为避免分数集中在低分区间，同时确保数据拥有足够的离散度以支撑稳健性分析，南非地区的TIMSS调研面向九年级学生开展。作为TIMSS调研的一部分，将向抽选学校中随机抽取的完整九年级班级发放数学与科学测试卷及背景调查问卷。

TIMSS通过收集学生、教师及校长填写的测试与问卷数据，计算学业成就得分，并分析与学业成就相关的各类影响因素。本调研的核心目标之一，是评估特定国家的教育系统运行状况。

本数据集包含理科教师对教师背景调查问卷的作答数据，涵盖学校对学业成就的重视程度、学校环境、从教情况、TIMSS班级教学相关情况等内容。所有理科教师均需完成该调查问卷。
