Abstract

Computational Thinking (CT) is a further development which is the latest innovation in mathematical problem-solving skills. Four foundations of CT make it easier for someone to solve problems effectively, efficiently, and optimally. This mixed methods research with an embedded design. Quantitative data were collected using tests and qualitative data through written interviews and an overview of the prospective teacher's thought processes in answering tests. The sample that became the research subject was selected using the purposive sampling method by selecting 28 pre-service teacher's mathematics in Professional Teacher Education (PTE) who attended CT lectures. The object of this research is the 4 CT foundations of prospective teachers in solving math problems. This study describes how CT skills solve problems. The test results show that the percentage of correct answers for each of the four CT foundations is more than 80%. It can be concluded that the knowledge and understanding of Computational Thinking for 21st-century professional teacher candidates in terms of 4 CT foundations are categorized as "very high". Based on the description of the student's answers, it was also concluded that the CT foundation is indeed the basis for thought processes in solving problems. It is the advantage of Computational Thinking.

Abstract

Writing scientific articles is crucial for a professional teacher. However, the reality shows that very few teachers are willing, able and accustomed to producing scientific articles. Based on the results of observations and discussions with teachers and heads of the Mathematics Teachers Association of Junior High Schools in the Northern Region of Solok Regency, it was found that teacher is facing two problems including motivation and techniques in scientific writing. Therefore, a solution to this problem is to hold data processing and scientific article writing training. The training was carried out in four stages, namely presentations and discussions, data collection, data processing with Microsoft Excel, and writing the results of data processing into a scientific article and learns how to publish it. The results of the teachers' personal self-evaluation showed that from this training there is an increase in their motivation and ability in processing data and writing scientific articles.
