This study is an attempt to analyze the individual merit of the INSTRAT model, which forms a cognitive process paradigm, and that of the Big6 model, which involves a functional approach, as tools for enhancing human information activities and aptitude. The former was examined through logical interpretations, while the latter was deduced from interviews using the Micro-Moment Time-Line method, a key methodology used in the Sense-Making Approaches. Results indicate that the application of the INSTRAT model is suitable for developing information systems that can assist users in the stage of defining information needs and search strategies, and that the application of the Big6 model is appropriate in information literacy education or information aptitude training. Of particular significance is the fact that the study proves for the first time that human information problem-solving behavior indeed follows the process delineated in the Big6 model.
