Abstract

A misconception is a problem that is often encountered in the world of education caused by several things, including students' initial prejudices, incompetent teachers, unclear textbooks, different contexts of the student experience, and teaching methods that only contain lectures. This study is intended to answer the problem regarding the effectiveness of cognitive conflict-based chemistry learning in reducing students' misconceptions about acid-base material. This research is quasi-experimental research with One group Pre-test and Post-test Design. The population in this study was all class XI IPA. The sample in this study was class XI IPA I. The instrument used in this study was a student's concept understanding test. The data collection method used is a multiple-choice reasoned test method. Changes in misconceptions were analyzed descriptively and statistically. A descriptive analysis was conducted to see changes in students' concepts. Statistical analysis using the T-test. Based on the research, it was found that the indicators of questions that experienced misconceptions were: Arrhenius acid-base theory (32.05%), Arrhenius acid-base classification (56.40%), Bronsted Lowry theory (43.59%), writing down the acid-base reaction equation according to Bronsted Lowry and Lewis acid-base theory (59.00%), distinguish between Arrhenius, Bronsted Lowry and Lewis acid-base theories (49.00%), the nature of acidic and basic solutions (47.00), degree of acidity/pH (79.00%), determination of strong acid (79.00%), determination of strong base (46.00%), degree of ionization in acid and base determination (46.00%) and application of the concept of pH in pollution (66.00%). Understanding of students' initial conceptions, namely students who are classified as knowing the concept of 23.18%, misconceptions of 53.95%, and not knowing the concept of 22.87%, while the understanding of the final conception of students is students who are classified as knowing concepts of 76, 20%, a misconception of 15.49% and not knowing the concept of 8.31%. Based on these data, it can be concluded that the cognitive conflict learning method is effective in reducing students' misconceptions

Abstract

The problem-based learning (PBL) method is one method to insert the competency targets of Education for Sustainable Development (ESD). This research aims to investigate how the implementation of ESD-oriented problem-based learning to metal and non-metal chemistry practical work.  The research method used in this research is a qualitative descriptive method and the research subject is the 4th-semester Chemistry Education university students. The research result shows that the ESD-oriented PBL method is applicable in metal and non-metal chemistry practical work. Practical work with the ESD-oriented PBL method can be used as an innovation for practical learning activities to achieve the ESD target competencies. Based on the questionnaires responded by the students, it can be concluded that the practical work with the ESD-oriented PBL method could increase the students’ ability for problem-solving with percentages of 33% strongly agree and 50% agree. Practical work learning with the ESD-oriented PBL affects the students to be more active in practical work activities. The stages of the PBL method help the students develop problem-solving abilities, and this is one target of ESD competencies.

Abstract

Autism is a neurological developmental disorder that affects communication, social interaction, and behavior in children. One of the therapies used to reduce autism symptoms is the Casein-Free Gluten-Free (CFGF) diet. This therapy aims to address metabolic disorders caused by the "leaky gut" syndrome, in which gluten and casein are not fully digested, resulting in opioid peptides that can affect brain function. This study focuses on the effectiveness of the CFGF diet in reducing autism symptoms, including improvements in communication skills, emotional responses, and cognitive function. According to previous studies, implementing the CFGF diet is reported to reduce autism symptoms by 60-70%. The implementation of this diet involves replacing foods containing gluten and casein, such as bread and cow's milk, with alternatives like rice flour and almond milk. Adopting the CFGF diet can reduce gut permeability and improve neurological function in individuals with autism. Additionally, this diet is also associated with improved sleep patterns and increased attention in children with autism, which in turn can enhance learning abilities. Nevertheless, the diet must be supervised to ensure that nutritional needs are met. Literature reviews indicate that the CFGF diet has a significant positive impact on reducing autism symptoms, including improvements in eye contact, social behavior, and engagement in group activities. Thus, the CFGF diet can be an effective alternative therapy to support the development of children with autism, especially in social, cognitive, and emotional aspects.
