Abstract

          The decline of student interest in STEM fields has been the subject of much discussion for educators and researchers. Therefore, a good gauge is required to ensure that the student is in good condition. The purpose of this study was to examine the validity and reliability of student interest in the STEM based on family background instrument, which consists of 50 items. The validity and reliability of the instrument were examined using Rasch Model Analysis (RMA), aided by Winsteps software version 3.71.0.1. A total of 150 students involved in this research. The output of instrument validity with RMA obtained (a) person and item reliability, (b) item difficulty level, (c) polarity item, (d) misfit item, (e) unidimensional, and (f) person map item. The findings showed that all the 50 items are reliable, valid, and compatible to measure student interest in the STEM based on family background. It is hoped that this instrument will be useful for teachers and researchers to apply in other studies. Future studies are needed to examine the effectiveness of student outcomes using the student interest in the STEM based on family background instrument.

Hi, thanks for your interesting topic. Here are my questions

1. What are the framework of criterion to design the clusters of items in your questionnaire?

2. The results from your study were successful. Will it be relevent and feasible in the Vietnamese contexts?

Dear CONG DAN,

Thank you for your interest in this paper.

1. What is the framework of criterion to design the clusters of items in your questionnaire?

The criteria for developing this questionnaire were based on aspects of student interest in the subjects of Science, Technology, Engineering, and Mathematics based on the family background of each student. Instruments conducted were questionnaires consisting of science (11 items), technology (11 items), engineering (11 items), mathematic (11 items), and family background (6 items). Details of the item developed can refer to this paper.

2. The results of your study were successful. Will it be relevant and feasible in the Vietnamese contexts?

Increasing people in STEM can improve the economic development of many countries (Schwab & Sala-i-Martín, 2012). The teaching and learning process with STEM integration is one of the topics that many countries discuss including in Vietnam. Therefore, I suggest another researcher use this questionnaire, especially in Vietnam.
