Psychometric Quality

An analysis was made of the educational and psychometric quality of standardized mathematics tests aimed at high school students. Trained raters judged most of such instruments available in the United States. Tests were categorized into four areas: general mathematics (N=322), applied mathematics (N=26), algebra (N=122), and geometry (N=52). Results showed many tests to be low in common types of validity and reliability. General mathematics had, as a rule, tests with higher ratings than did the other content areas. Several implications were drawn from the study. Researchers in mathematics education should carefully analyze all aspects of tests to find those congruent with a given research need. Test developers should make renewed efforts to enhance the technical quality and curricular relevance of their products.

There is a gap between the quantity and quality of research in Indonesia. It is assumed that the research skills of the researchers are still low. Meanwhile, research skills development still relies on the higher education level. Efforts are needed to develop research skills from an early age. This study aims to examine the use of APL in the authentic science approach to develop research skills of junior high school students. The quasi-experimental method was carried out by inviting 81 students from two classes of 7th grade in a state middle school in Bandung, Indonesia. They analyzed three Adapted Primary Literatures with the jigsaw and NHT models. Before and after learning, students took research skills tests. The research instrument has passed the validity and reliability tests. Descriptive and inferential analyses were done. The results of data analysis indicate that the use of APL in the authentic science approach in both learning models can develop students' research skills. Furthermore, the jigsaw model is more recommended to use. This study recommends the use of APL as a science learning resource to develop students' research skills as a beginning to introduce the scientific method.
