“…Poor perception can affect students' interest in chemistry. According to [12] students are interested in experimental activities in learning chemistry, but they consider chemistry as a complex science lesson with abstract symbols and terms that must be memorized. Teacher skills in conveying abstract concepts influence student interests.…”

The purpose of this study is to describe the characteristics item questions of chemistry national standardized school exam and identify students' difficulties in answering questions. Data collection was carried out by documenting results of the exam in 2018 in Kupang city. The documentation was consisted of 35 multiple choice questions, keys answer and test results of 103 samples students. This research was a descriptive exploratory study. Data analysis was carried out quantitatively and qualitatively. Quantitative data analysis was performed using the classical test theory approach and item response theory with 1 logistical parameter. Qualitative data analysis was carried out to describe the items that were included in the category of difficult levels of distress and poor differentiation, by means of focus group discussion (FGD). The results showed that there were 8 difficult items out of 35 student test items. Base on the results of FGD, the students' difficulties in answering questions were caused by a lack of conceptual understanding in calculating and using complex formulas. The results of the estimated reliability of the questions amounted to 0.83 which showed that chemistry national standardized school exam questions were in the good reliability category.

“…It is common knowledge that chemistry is present in our lives, for example in medical drugs, energy drinks, fuels, detergents, fashion, climate change, sports, communication, health issues, nanotechnology, or food. − However, when concepts studied in the classroom are related to everyday life in our society, as in the present case with the contextualization of stoichiometry exercises with haute cuisine, students pay more attention and they are more interested . Thus, they must not see the contents of chemistry as concepts that they only have to understand or memorize for the final exam. − …”

“MasterChemist”: A Novel Strategy for Reviewing Stoichiometry and Introducing Molecular Gastronomy to Chemistry Students

2022

This article presents and discusses the results of an educational innovation that seeks to introduce the world of molecular gastronomy in chemistry lessons as a means to review stoichiometry and offer an alternative way to learn. In the literature to date, there is no evidence of haute cuisine having been employed to contextualize stoichiometry problem statements with its everyday applications. The proposed novel strategy, called “MasterChemist”, involved the participation of Spanish first-year university students taking the subject General Chemistry in the Bachelor’s Degree in Chemical Engineering. A Game-Based Learning (GBL) approach was used to solve the exercises and make the activity more appealing and interesting by adding fun to the learning process. The problems were contextualized in the use of siphons, isomalt sugar, and the spherification technique. Furthermore, dividing students into groups also boosted their cooperative skills. The students’ answers to a final survey revealed that the general opinion regarding the activity was highly positive. The undergraduates reviewed some stoichiometry concepts which we had previously observed that they had problems understanding. In addition, the attractive theme of haute cuisine made the activity dynamic and enjoyable both for students and for the teacher.

“…Vários autores referem que a investigação do Ensino da Química revela ainda vários outros obstáculos à sua aprendizagem, nomeadamente, dificuldades de nível afetivo e atitudes negativas em relação à Química (Gulacar et al, 2018) bem como barreiras cognitivas (Organización para la Cooperación y el Desarrollo Económicos [OECD], 2016) pelo facto da Química ser considerada pelos alunos como irrelevante, aborrecida e desajustada à realidade (Sausan et al, 2018).…”

Objetivo. Avaliar de que modo as tarefas desenvolvidas pelos alunos no âmbito do projeto educacional de ciência cidadã PVC de monitorização da qualidade das águas costeiras contribuíram para a promoção da sua consciencialização para a problemática do lixo marinho, em particular, da poluição do oceano por plásticos e por microplásticos e para a importância da Química na sociedade. Metodologia. A etapa do projeto que aqui se apresenta era constituída por um conjunto de seis tarefas assíncronas, realizadas com mediação digital através da plataforma Moodle que decorreu durante o ano letivo 2018/2019 e envolveu 442 alunos e nove professores do 3.º Ciclo do Ensino Básico da região norte litoral de Portugal. Dados sobre o impacto na consciencialização dos alunos para os contextos abordados foram recolhidos a partir dos registos elaborados pelos alunos em cada tarefa, e foram, posteriormente, analisados com recurso à técnica de análise de conteúdo. Discussão. Da análise destes resultados emergiram indicadores do contributo positivo do projeto PVC na consciencialização dos alunos para a poluição dos ambientes marinhos por (micro)plásticos bem como na sensibilização para o papel da Química na sociedade, tendo os alunos demonstrado opiniões positivas face a esta ciência e reconhecido as suas inter-relações com outras áreas da ciência e da tecnologia. Conclusão. Constatou-se assim que, através da exploração de contextos atuais e relevantes, que os projetos de ciência cidadã apresentam um grande potencial na promoção da sensibilização dos alunos para as temáticas químico-ambientais.
