Abstract

The rapid development of science and technology is a challenge for the era of disruption in the 21st century. These phenomena cannot be separated from the hard work of scientists who have scientific habits of mind (SHOM). Science learning that focuses on SHOM can be indicated by the scientific attitude of students during learning, so the benefits of SHOM are to bring out scientific attitudes in students. In addition, SHOM needs to be taught to students so they can solve problems in a structured and systematic way. This study aims to describe the SHOM profile of high school students on chemical equilibrium with the topic of health and the environment. This research includes quantitative descriptive research. The number of samples from this study was 80 students taken from one of the high schools in Magelang City. The data collection technique in this study was a questionnaire. The data research instrument used was a student questionnaire sheet which was a closed questionnaire with five choices namely SD (Strongly Disagree), D (Disagree), QA (Quite Agree), A (Agree), and SA (Strongly Agree). The number of statements that students have to answer is 25 items with details of 14 statements with positive meaning and 11 statements with negative meaning. Then, the data were analyzed by ideal criteria assessment The results of the research that has been done can be seen that the SHOM profile on chemical equilibrium material is 66.7427%. These results indicate that the students' SHOM profile on chemical equilibrium material is classified as fair. So learning modifications are needed such as modification of learning activities, use of learning models and strategies that encourage students to think scientifically, as well as selection of appropriate learning media in order to improve scientific habits of mind.

Abstract

One of the challenges of the 21st century disruption era is the fast development of science and technology which was initiated by the hard work of scientists who have habits of mind. Habits of mind can be deepened into scientific habits of mind (SHOM) and can be encouraged to be used by students at the high school level. This research aims to develop and validate the SHOM questionnaire in chemical equilibrium. Modified 4D becomes an adapted development model. The questionnaire developed has 25 statement items originating from seven aspects of SHOM. Content validity was calculated using the Aiken V equation and involved seven expert judgments with 4 categories of answer choices and produced an average of 0.90, so the questionnaire tested content validity. Construct validity was calculated using the Pearson correlation coefficient involving 300 respondents from 7 public high schools and produced a mean of 0.581 which was above the r table (r table value = 0.113), thus meeting the construct validity criteria. The reliability of the questionnaire was calculated using Cronbach Alpha and got a mean score of 0.915 and the reliability was included in the very high category. Based on these findings, the SHOM questionnaire developed can be declared suitable for measuring SHOM for high school students.

Abstract

Chemical literacy, the ability to integrate the understanding of chemistry with everyday life phenomena, has become a necessary skill for high school students. This skill is aimed at enabling students to develop an understanding of chemistry concepts about the environment, health, and industrial topics. This research focuses on developing and validating a chemical literacy assessment, specifically on chemical equilibrium. Afterward, the assessment was given the name Chemical Equilibrium Literacy Assessment. The development model is based on modified 4D and consists of two sets of 15 questions each. Content validity was measured using the Aiken V equation with seven expert judgments and four answer categories. To assess construct validity, the Pearson equation was used involving 100 respondents. The reliability of the assessment was calculated using Cronbach's Alpha. The results of content validity, construct validity, and quality of test items indicate that the chemical literacy assessment on chemical equilibrium material on environmental, health, and industrial topics has relatively high results. This assessment can be used to measure the chemical literacy abilities of high school students after studying chemical equilibrium.

Abstract

This study aims to examine the effect of the LIRACLE model (Literacy and Research-Oriented Cooperative Problem-Based Learning) on student activeness in undergraduate chemistry learning. LIRACLE is an innovative instructional model that integrates literacy strategies, cooperative learning, and research-based approaches within a problem-based learning framework. The study employed a quasi-experimental design with two groups: an experimental group (38 students) that received the LIRACLE treatment and a control group (44 students) that followed conventional PBL. Student activeness data were collected through observation sheets over six class meetings and analyzed using the Mann-Whitney test due to the non-normal distribution of the data. The results showed a significant difference in student activeness between the experimental and control groups, with a significance value of 0.000 (p < 0.05). Students who participated in LIRACLE-based learning demonstrated higher levels of engagement, both cognitively, socially, and affectively. The implementation of LIRACLE proved effective in creating a participatory and reflective learning environment, encouraging students to take an active role in constructing their understanding. These findings support the importance of developing active learning strategies in higher education, particularly to achieve meaningful chemistry learning outcomes in alignment with Sustainable Development Goal 4.
