IMPLEMENTATION OF SSI CONCEPT MAPPING AS A DYNAMIC LEARNING ENVIRONMENT TO ENHANCE STUDENTS' SCIENTIFIC PERFORMANCE

The presented research focuses on verifying the confluent application of concept mapping (CM) and socio-scientific issues (SSI) according to the value-laden and moral dilemma orientation to construct problem-solving performance. This research sets up some perspectives for all 146 participants, including 139 students and 7 experts. All findings reveal that the design of SSICM contexts includes a rebuttal process and incense claim to improve students' argument response (16.4%), to increase content knowledge and illuminate their science learning by argumentations. To develop an assessment tool with high validity and reliability (Cronbach's α > .9) and find positive presentations of all learning attitudes in the SSICM context, learning environment and results will concern the best argumentation process. Students’ interview responses and SWOT analysis of teachers indicate that SSICM's use of argument in the classroom is a real benefit. The research provided a better paradigm of attempts to combine analytical and academic hypotheses to explain literature sources by teachers, researchers, textbook developers, and editors. Keywords: concept mapping (CM), problem-solving, socio-scientific issues (SSI), SSICM contexts

POSITIVE PRESENTATIONS OF SURFACE BRAID GROUPS

We provide new group presentations for surface braid groups which are positive. We study some properties of such presentations and we solve the conjugacy problem in a particular case.
