Abstract

This research is motivated by the fact that problem solving is a basic ability that every student must have. However, observations in the field show that students' mathematical problem-solving skills, especially in the material of algebraic form operations, are still relatively low. This study aims to describe students' mathematical problem-solving skills based on Polya's theory, which consists of four stages: (1) understanding the problem, (2) planning problem solving, (3) implementing the plan, and (4) re-examining the results. This study involved 26 ninth grade students as subjects. The method used was descriptive qualitative with data collection techniques including tests, interviews, and documentation, data analysis conducted based on four levels of problem-solving ability: excellent, good, sufficient, and deficient. The results showed that students' mathematical problem-solving ability on algebraic form operation material obtained as a whole was still relatively low with a scale of 42%. The implications of these findings indicate the need for the alication of more varied and contextualized teaching strategies to improve students' problem-solving skills. This research can be the basis for teachers in providing further assistance to students who are experiencing difficulties, focusing on improving skills in understanding and solving mathematical problems as a whole.

Abstract

Numeracy literacy is a very important skill in the 21st century. However, the numeracy literacy rate in Indonesia is still low, this can be seen from the results of the PISA test and various observational studies in schools. One way to overcome this problem is by applying the Problem Based Learning (PBL) model. The aim of this research is to determine the improvement numeracy literacy through the PBL model. The research method used is meta analysis with a sequence of preparation, implementation and analysis stages. The analyzed articles were 10 articles, with the criteria of each article discussing the PBL model for numeracy literacy, and there was information about the mean and standard deviation. The results obtained are that students' numeracy literacy through the PBL model has increased, where . It was concluded that there was a significant difference between the pre-test and post-test literacy numeracy scores before and after the PBL model. The average pre-test and post-test scores are 62.54 and 77.92 respectively, numeracy literacy in the post-test is higher than in the pre-test, so it can be concluded that the PBL model can increase students' numeracy literacy. The articles analyzed have similarities and differences in results and views because many aspects are applied. There were 2 different studies found, both of which received an Effect Size (ES) value of 0.09 and were categorized as small, so further research related to PBL on numeracy literacy, especially at the elementary school level, considering that in this meta analysis only used 1 data with the elementary school level whose results were not significant.

Abstract

Students' understanding of physics will increase along with learning during lectures, but thoughts on this understanding can be flexible and not always permanent, so it is necessary to explore other students' thoughts (resources) that may not have been discussed in previous research. This article focuses on the conceptual analysis of resources, namely the ideas they use in solving problems related to work-energy issues. This research aims to identify the resources used by physics students in work-energy reasoning as a work to explore students' new thoughts that have not been discussed in previous research. The research was conducted on 92 new physics department students in 2023 who took Basic Physics I lectures. Before the test was given, the lecturer gave a short review of the work-energy theorem to remind them of the knowledge they had learned in high school. The results of the research reveal that the resources that are widely used by students are (1) the concept of work in physics which is associated with the understanding of work in everyday contexts, namely as work/work/work, (2) in reasoning about motion phenomena involving potential energy and kinetic energy for students. directly apply the principle of conservation of mechanical energy. It is hoped that these findings will be useful input for lecturers in designing lectures on the topic of work-energy theorem based on resource theory or knowledge in pieces.

Abstract

DNA recombinant technology is a tool that could support thedevelopment of pharmacogenomic detection such as for CYP2D6 copy number detection application. The housekeeping gene was identified as an internal control alternative for the copy number of the CYP2D6 detection component. There are many kinds of housekeeping genes, including albumin. In this report, we have successfully TA-cloned partial albumin to support the development of CYP2D6 copy number detection. TA-cloning was successfully confirmed with white-blue methods in media LB + ampicillin + IPTG + X-Gal and with colony PCR methods. Further, we made a standard curve with this recombinant plasmid to evaluate albumin qPCR efficiency and showed high-efficiency qPCR 0,9914 (99%). Based on the CYP2D6 copy number developed, the test in this study showed low concordance with high reproducibility Long PCR, indicating that the nucleotide base area of albuminand CYP2D6 in this studywas not recommended for CYP2D6 gene multiplication detection.
