THE DEVELOPMENT OF THE MATHEMATICAL LOGIC INTELLIGENCE ASSESSMENT INSTRUMENT
Main Article Content
Abstract
Mathematical logic intelligence leads to the ability to think systematically, logically, and scientifically. This intelligence supports learning outcomes not only in the realm of mathematics but also in other fields such as physics, chemistry, statistics, and so on. So far, there has yet to be a valid and reliable mathematical logic intelligence assessment instrument for students in elementary schools or Madrasah Ibtidaiyah. This study aims to develop a valid and reliable mathematical logic intelligence assessment instrument for Madrasah Ibtidaiyah students. The research method is research and development with nine steps: (1) determining the purpose of preparing the instrument, (2) looking for relevant theories or material coverage, (3) preparing indicator items, (4) preparing instrument items, (5) validating the content, (6) revision based on validator input, (7) conducting trials on appropriate respondents to obtain participant response data, and (8) conducting analysis, and (9) assembling the instrument. The research instruments used tests and validation sheets. Instrument validation in the form of content validation and construct validation by three experts in mathematics learning at the Madrasah Ibtidaiyah. The test was conducted on grade V students doing the limited experiment. The study's results produced a test to measure mathematical logic intelligence in as many as nine items, which were valid and reliable items with a coefficient of 0.793. The mathematical logic intelligence assessment instrument consists of five indicators, namely: logical thinking with the ability to organize ideas systematically, abstract thinking with the ability to understand complex mathematical concepts, deductive thinking with the ability to conclude from given premises, inductive thinking with the ability to collect data, and analytical thinking using the ability to analyze and solve mathematical problems.
