Abstract

Making medical decisions while distracted when receiving COVID-19 misinformation can majorly impact a person's life and even lead to death. Blatantly sharing COVID-19 misinformation is a significant problem of human behavior that triggers a speed-up and acceleration in the propagation and diffusion of misinformation in social media. While the latest research has focused on understanding the psychological dimensions of this phenomenon, few studies have explored the role of selective exposure and technological prevention when a person considers sharing COVID-19 misinformation, primarily through an Implicit Association Test (IAT). Our study identified and intervened in the association of user exposure between misinformation and implicit truth evaluations by using the Implicit Association Test (IAT) with "Misinformation vs. Fact Information or Positive vs. Negative Words”, 38 from 150 participants were either exposed to misinformation headlines or actual new headline posts on stimulants, in the form of images. We then measured participants' implicit truth evaluations and self-reported perceived accuracies of actual and of misinformation headlines using the Visual Selective Attention System (VSAS). After intervening, participants exposed to fake news headlines had lower implicit truth evaluations and increased perceived accuracy. This implies that exposure to fake news headlines after the intervention with the VSAS system may have directly affected implicit evaluations and changed user behavior in sharing COVID-19 misinformation.

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

This is very important in growing students' environmental awareness through integrating green chemistry in learning as one of the efforts to protect the environment and reduce environmental pollution. Chemistry learning through green chemistry education has great potential in developing ethics as a method for solving environmental problems. Green chemistry has 12 principles that are expected to address pressing environmental problems such as pollution, waste management, energy shortages, and workplace safety and security. This research type is descriptive. As much as 77% of the average students in this study with a good enough category indicates that green chemistry has an important role in building chemistry ethics. Ethics is used in general to describe human attitudes towards a problem. Ethics education in chemistry with a green chemistry perspective is carried out by teaching and training integrated into courses with the hope that it will become ethical habituation that will build chemistry ethics.

Abstract

Lead (Pb) is a toxic heavy metal for humans. Agrochemical applications contribute to Pb contamination and accumulation in plants which is harmful to humans. This study aims to investigate the habits of horticultural farmers in applying inorganic fertilizers and pesticides intensively on Pb concentration in the soil and cultivated plants, and its effect on plant growth. The measured parameters consisted of soil and plant Pb content, soil pH, organic C, total N, available P, and exchangeable K. This study used a randomized block design consisting of 4 treatments (Control (KT); (PR); (TN); and (TP)). The results showed that horticultural farmers' dosage of inorganic fertilizers exceeded Indonesia Ministry of Agriculture recommendation. The application of inorganic fertilizers and pesticides by farmers (business as usual) increased Pb content in plants up to 31.46 mg/kg. Besides the application of inorganic fertilizers increases fertilizer residues in the soil by up to 65%, which increases environmental pollution even though the application of inorganic fertilizers increases plant growth and production (shoot length,  the number of leaves, and plant dry weight). Thus, wisely applying agrochemicals is required in order to support plant growth and production without further environmental problems.

Abstract

This research aims to describe teachers' understanding of Culturally Responsive Teaching (CRT), difficulties to implement it, and its relation to higher order thinking skills through descriptive qualitative method using interview instrument. The research subjects were twenty science teachers from three senior high schools that have implemented Independent Learning Curriculum in Medan City and Deli Serdang Regency in North Sumatera. The results revealed that 70% of teachers have limited understanding and only 30% of the teachers who understand the concept of this learning correctly. The research results also showed that only 20% had ever implemented CRT in their classrooms and 80% had never implemented. This is all due to difficulties. Based on previous research, it shows that CRT make many positive contributions to learning processes and outcomes, improving the learning process and outcomes, improving higher order thinking skills and building student’s character. Therefore, teachers need to understand, be able to design and implement learning model based on CRT to serve diverse students.

Abstract

Differentiated learning is the core of the independent curriculum now. The aim of this research is to develop an instrument for measuring the cognitive learning outcomes of high school students based on differentiated learning on elasticity material and to obtain its characteristics. Differentiation, in this case, is differentiation of student learning styles. The instrument grid is arranged based on indicators of cognitive learning outcomes, which are then used to compile question items. The test instrument consists of two test sets, each of which has 9 items including two anchor items so that the total number of items is 16 items and has been validated by 6 experts. The validated instrument was tested on 252 respondents spread across high schools in the low, medium and high categories. Dichotomous data were analyzed using the Partial Credit Model (PCM). The trial results showed that all 16 items and the differentiated learning-based student cognitive learning outcomes test instrument were proven to be valid, fit the PCM model, and reliable, which means all items were in the good category. Thus, the test instrument developed meets the requirements for measuring the cognitive learning outcomes of high school students on elasticity material based on differentiated learning.
