The purpose of the study was to determine the perceptions that senior high school (SHS) chemistry students and teachers have about organic chemistry as well as to compare organic chemistry topics that are difficult for students and teachers. Simple random sampling (lottery) and purposive sampling methods were used to select a sample of one hundred (100) SHS students who studied elective chemistry and ten (10) chemistry teachers. The research instruments used to collect data for this study were the ‘organic chemistry perceptions questionnaire for students’ (OCPQS) and ‘organic chemistry perceptions questionnaire for teachers’ (OCPQT). Descriptive statistics (frequencies and percentages) were used to analyze the data collected. The findings revealed that these SHS students have a fairly positive perception of organic chemistry while their teachers had a highly positive perception of organic chemistry. Preparation and chemical reactions of alkenes, preparation and chemical reactions of alkynes, structure and stability of benzene, reactions of benzene, comparison of reactions of benzene and alkenes, petroleum, polymers and naming of alkanes and structural isomerism were perceived by students as difficult to understand. The rest of the Ghanaian SHS organic chemistry topics (26 out of 34 topics) were perceived as easy to understand by students. Also, the teachers perceived all the SHS organic chemistry topics as easy to teach with the exception of reactions of benzene. The insights gained about teachers’ and students’ perceived difficult organic chemistry topics in this study imply that teachers’ perceptions and how these are communicated to students can have significant effects on learning. The authors believe that both teachers and learners could benefit from this increased awareness of perceptions about difficulties in teaching and learning organic chemistry. They therefore suggest that further studies into how teachers’ perceptions influence their teaching and consequently their students’ experiences be carried out. In addition, in future research, a diagnostic test based on the topics in the SHS organic chemistry syllabus could be added to ascertain whether the perceived difficult topics are actually difficult for students to answer questions on. This would help teachers to separate perceived difficulties from the actual difficulties (realities) and be able to address them in their lessons.

The 21st-Century skills are skills that must be possessed by students to compete in the era of globalization. The provisioning of these skills to students can go through the physics learning process at school. Introduction, Connection, Application, Reflection, and Extension (ICARE) learning model is one of the learning models that can be applied in Physics learning in high school to train students' skills in critical thinking, creative thinking, communication, and collaboration. The purpose of this study was to determine the improvement of communication and collaboration skills of students after applying the ICARE learning model. The research method used was quasi-experimental with a single-group interrupted time series design. The sample were high school students in one of the Karawang districts, consisting of 12 male students and 15 female students. During the learning activities, students will be given a worksheet with several different questions each meeting tailored to the material being studied, and the answer will be used as a source for analyzing their written communication skills. These questions lead students to be able to communicate the results of their experiments following scientific principles. Experimental activities conducted by students will be analyzed to measure their collaborative skills, and students' presentations will be used to measure their oral communication skills. The improvement of those three aspects was analyzed at each meeting. The results showed that the implementation of learning using the ICARE approach was able to improve the ability of students to collaborate with an average score of 7.87 at the first meeting to 15.93 at the second meeting. While the communication, especially report-writing skills of students, increased from the average of1.53 at the first meeting to 3.6 at the second meeting. The aspect of making presentation material increased from 1.67 to 3.17, and the aspect of oral presentation increased from 1.53 to 3.53 at the second meeting. Based on the results obtained, it can be concluded that students' communication and collaboration skills improve after the ICARE learning model implemented

Abstract The aim of this study was to ascertain high school students' proportional reasoning in the sense of the COVID-19 pandemic. How do students' thoughts flow when confronted with problems requiring proportional reasoning? This research is a mixed study by collecting data through problem-solving questions to 253 junior high school students in Muaro Jambi, Jambi Province, Indonesia. The problem-solving activities are based on real-world scenarios and require reasoning that is proportional and pertinent to the COVID-19 pandemic context. Due to the ongoing COVID-19 pandemic, the test is administered through the Whatsapp framework. Students' responses are examined in detail to ascertain their proportional reasoning skills. The results indicate that almost all students correctly answered the first question. However, only a small percentage of students were able to answer to and make the correct argument for the second question. The findings indicated that students demonstrated a reasonable level of proportional reasoning when confronted with the COVID-19 pandemic situation. According to the findings of this report, it is important for teachers of mathematics to establish learning activities and problem-solving tasks that help students improve their proportional reasoning skills. Keywords: COVID-19; Problem Solving; Proportional Reasoning; Real-World Situations AbstrakTujuan dari penelitian ini adalah untuk menggali penalaran proporsional siswa SMA  dengan konteks pandemi COVID-19.
