Abstract

This study aims to produce a web-integrated investigation worksheet about protists that is valid, practical, and effective by following the McKenney & Reeves development model. The validity of the worksheet was obtained by filling out a validation questionnaire by teaching material experts and microbiology experts. The practicality of the worksheet was obtained through filling out response questionnaires by students and biology teachers. Meanwhile, the effectiveness of the worksheet was obtained from the difference in students' pretest and post-test scores. The results of filling out the validation questionnaire and response questionnaire were analyzed using percentages while the difference in student test scores was analyzed using paired t-test. The average of expert validation results obtained a value of 88.6% (valid). Implementation on 30 students of class X IPA SMA Islam Kepanjen Malang using the group investigation learning model showed that the worksheet proved to be very practical based on the average response which amounted to 89.3%. In addition, the paired t-test results showed that there was a big difference between the students' test scores before (M = 37.500, SD = 13.310) and after using the worksheet (M = 77.033, SD = 13.013), t(29) = 18.203, p <0.001, d = 3.323. So, it can be concluded that the web-integrated investigation worksheet about protists is considered valid, very practical, and effective.

Abstract

A module is a learning media that is arranged systematically so that it is easy for students to use when receiving material taught by the teacher. Learning in schools using information technology is still not optimal, so it is necessary to develop electronic modules. Moreover, Indonesian students have low critical thinking skills. This study aims to create electronic modules that effectively improve students’ critical thinking skills. The method applied is Research and Development. The effectiveness of the developed electronic module can be determined by carrying out the N-gain test, which is obtained from evaluating students’ skills before and after using the generated module. The Kolmogorov-Smirnov normality test shows a significance score of 0.000 on the pre-test and post-test, which means that it is not normally distributed, so it is continued with the Wilcoxon test. The Asymp.Sig (2-tailed) of the Wilcoxon test is 0.000, meaning there is a difference between the scores before and after implementing the developed module. The average score of N-gain in the critical thinking skill variable is classified as a high category, namely 0.73. Conclusions are drawn regarding using the Predict-Observe-Explain (POE) model in electronic modules that can improve critical thinking skills, proven effective in learning physics.

Abstract

With the correct approach to education, students may develop their capacity for critical thinking. With the use of the phypox app, this research intends to detail how well a problem-based learning paradigm may improve students' critical thinking abilities. Eleven students from Science 2, 4, and 5 at SMA Negeri 22 in Surabaya participated in this quasi-experimental study by taking pre- and post-tests as a group. A quantitative descriptive approach was used for data analysis. With an average n-gain score of 0.80 for XI Science 2, 0.83 for XI Science 4, and 0.78 for XI Science 5, the findings demonstrated that students' critical thinking abilities increased. Classes 4 and 5 of the XI Science program had the greatest and lowest n-gains, respectively. And a Non-Parametric Anova Test result of 0.13 was achieved. After considering the evidence, it is clear that phypox-assisted problem-based learning significantly enhances high school students' critical thinking abilities.

Abstract

Cocoa beans can inhibit the growth of pathogenic bacteria such as Streptococcus Mutans. Utilization of cocoa bean extract as an anti-bacterial inhibitor containing chemical compounds extracted in simplicia aims to increase the content in the form of alkaloids, flavonoids, tannins, saponins and polyphenols. Streptococcus Mutans is a gram-positive facultative anaerobic coccus that is usually found in the human oral cavity and one of the causes of tooth decay or cariogenic bacteria capable of creating an acidic atmosphere in the mouth and can metabolize carbohydrates. This paper describes the effect of the concentration of cocoa bean extract on the diameter of the clear zone of Streptococcus Mutans bacteria. The antibacterial test was carried out using the Mueller Hinton Agar (MHA) method, samples of cocoa bean extraction were prepared by maceration method with varying concentrations of 2.5% to 12.5% ​​at 2.5% intervals. With an interval of three hours, measurements were carried out for 48 hours of observation. The results showed that the greater the concentration of cocoa bean extract, the larger the diameter of the clear zone, with the smallest diameter (8.44 ± 1.61) mm (for a concentration of 2.5%) and the largest diameter (9.70 ± 1.66) mm (for a concentration of 12.5%).

Abstract

Chemistry is considered an abstract discipline, characterized by many concepts that make students uninterested in engaging in its learning. One approach to stimulate interest is through the application of contextual learning, where acquired knowledge is applied in a practical context. The purpose of this journal review is to provide insight into the implications of using contextual approaches in chemistry education, particularly about fostering student interest and engagement in the subject matter. The research design used in this study was a systematic literature review using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) as a tool and guide for evaluating articles. The search for articles published in Scopus and Web of Science using the selected keywords: contextual approach, learning interest, and its extension based on the selected PICO framework. Based on the search results, 50 articles were obtained to be analyzed. Findings from diverse data consistently show that the application of contextual or everyday learning approaches contributes to increasing students' interest in learning, especially in the chemistry domain. Students' interest in learning chemistry has a significant influence on their learning outcomes, motivation, and critical thinking levels. This is because the greater the student's interest in learning chemistry, the stronger the curiosity and understanding of the subject matter. When students have a strong understanding of the subject matter, their critical thinking skills and chemical learning outcomes improve.
