Abstract

The aims of this study was to find whether there was an influence of the Problem Solving Model towards critical thinking skills of students of grade XI in SMAN 9 Padang. A Quasi Experiment method with The Post-test Control Group Only Design was used in this study. Students were grouped in an experimental group (Problem Solving model) and a control group (Direct intruction). The data from a test were analyzed using t-test with a=0,05. The findings showed that there was a significant difference of critical thinking skills enhancement in experimental group than the control group.

Abstract

Covid-19 has an impact on all aspects, including aspects of education. During the pandemic, the learning process is online. It minimizes direct interaction between individuals to break the chain of the spread of the corona-virus. The aim of this study was to find the problems during the online learning process. That it can be used as an evaluation material for a better learning process. The study was conducted with library research. Sources of research data obtained from articles, publication journals, books, and statically data. The analysis technique used content analysis of literature and articles with are the source of research data. The problem during the online learning process include a decrease in the enthusiasm for learning students, a lack of understanding of the material by students, and the effectiveness of online learning. Problems during the online learning process are expected to be an evaluation to be able to improve the learning process even better.

Abstract

Chromosomes become an important substance for an organism because they contain information useful for cell regulation and as a hereditary agent. The character of an organism is determined by genes located on chromosomes. Changes in chromosomes will have a significant influence on the evolution of a species. One of the factors that influence changes in chromosomes is mutation. Mutation is a form of defense of an organism in the face of the changing state of nature. Neacomys diversification is caused by gene fusion events, translocations, amplications, and constitutive heterochromatin (CH). In the family Crenuchidae genus Caracidium there was a revision in the diversification of chromosomes 2n of 50 chromosomes composed of 32 metacentric + 18 sub-metacentrics. This is due to differences in the number of rDNA sites, heterochromatin blocks, number of B chromosomes and the size of sex chromosomes, as well as repeated DNA dynamics on chromosomes observed among species forming diversification and chromosomal speciation. In the boidae family reptile class there was a fusion of chromosomes which resulted in the conclusion that the kariotype configuration in snakes is currently the clade of primitive Neotropic snakes.
