A conceptual framework of the modes of problem-solving action has been developed on the basis of a simple relationship cone to assist individuals in diversified professions in inquiry and implementation of theory and practice in their professional development. The conceptual framework is referred to as the Cone-Deciphered Modes of Problem Solving Action (MPSA cone). The conceptual framework of the MPSA was formulated by examining and integrating pragmatism, critical science theory, three modes of inquiry, and practical reasoning. The relationship cone-deciphered MPSA reflects three modes of problem-solving action that interpret these three types of thinking: disposition, research, and knowledge acquisition methodology. The technical model of problem-solving action is illustrated on the top of the MPSA cone, the interpretive mode of problem-solving action is in the middle, and the emancipating mode of action (seeking reasonable, morally defensible, and consensus value ends and taking social action to ensure them) is at the widened base. The knowledge of three modes of problem-solving action may be useful for professionals in fields, including education and information technology, when their fields are engaged in activities such as inquiring about and interpreting humans' cognitive structure while studying the inclination or preference of people retrieving the information presented by technology experts, knowledge acquisition, or staff training.
