We assess and compare computer science skills among final-year computer science undergraduates (seniors) in four major economic and political powers that produce approximately half of the science, technology, engineering, and mathematics graduates in the world. We find that seniors in the United States substantially outperform seniors in China, India, and Russia by 0.76–0.88 SDs and score comparably with seniors in elite institutions in these countries. Seniors in elite institutions in the United States further outperform seniors in elite institutions in China, India, and Russia by ∼0.85 SDs. The skills advantage of the United States is not because it has a large proportion of high-scoring international students. Finally, males score consistently but only moderately higher (0.16–0.41 SDs) than females within all four countries.

STEM literacy in education aims to be able to prepare students to be able to compete in the world of education in the world of work in the future. The benefit of STEM Literacy is that it makes students more skilled in all areas including science, technology, mathematics, and engineering. In ad- dition, STEM literacy can also make students improve their critical thinking skills and become crea- tive, logical, innovative, productive and relate directly to real conditions. This study aims to analyze the needs of students' STEM literacy achievement assessment in learning biology. The type of research used is descriptive, with data collection techniques carried out by conducting observations and inter- views. The results showed that biology learning has been implemented based on STEM literacy, stu- dents are still less enthusiastic in reading, students are more interested in learning related to technol- ogy, teachers do not know the assessment of students' STEM literacy achievement in biology learning.

Linguistic intelligence is one of eight multiple intelligences that currently attracts attention in the world of education. Linguistic intelligence is a person's ability to speak both verbally and in writing, besides that people who have linguistic intelligence also master the components of linguistic intelligence which consists of phonology, syntax, semantics and pragmatics. The type of research used is research and development (R & D) with a 4D model. The subjects in this study were experts as validators, fifth grade students for trials and homeroom teachers in elementary schools. Data collection is done by giving a questionnaire to the validator. In this study the researchers concluded that the product of the developed linguistic intelligence assessment instrument was declared feasible to be used based on the results of validation of 86% with very feasible categories. The obstacle in developing the product of this instrument of linguistic intelligence assessment is the lack of knowledge of the school about the importance of linguistic intelligence for students in elementary schools.

Abstract Deoxynivalenol (DON), one of the most prevalent mycotoxins in the world, and is capable of inducing immune disorders in humans and animals. The aim of this study was to determine the effect of feed contaminated with DON on the number of TLR2- and TLR9-positive cells and their mRNA expression in the porcine large intestine. The experiment was conducted on two equal groups of pigs (n=4). The experimental group (E) was administered feed contaminated with DON (1008 μg/kg of feed) for 6 weeks, and the control group (C) was administered non-contaminated feed over the same period of time. A decrease in the expression of TLR2 mRNA was noted in the cecum. The percentage of TLR9-positive enterocytes increased in the ascending colon and decreased in the cecum. The results of this study indicate that DON can modify the local immune response by changing the expression of TLRs.
