Citizen Science as a Pedagogical Tool in Chemistry Education: Students’ Attitudes and Teachers’ Perceptions
Interdisciplinary Journal of Environmental and Science Education, 2022, 18(2), e2271, https://doi.org/10.21601/ijese/11841
ABSTRACT: The need of promoting the affective dimension of chemistry literacy in students, through expressions of interest in chemistry-related topics and positive attitudes toward this field, has been emphasized in chemistry education. Thus, the purpose of this study was to understand students’ attitudes toward chemistry between the ages of 12 and 14, as well as how their participation in a citizen science project called Perceiving the Value of Chemistry behind water and microplastics (PVC) contributed to possible attitude changes. Although the research focus was chemistry education, chemistry and physics are taught as part of one subject in Portugal, so the attitudes towards physics and chemistry scale was used as a pre- and post-test. The pre-test showed positive attitudes towards physics and chemistry. In the post-test, the control group exhibited significantly negative changes in attitude, in all dimensions; whereas the experimental group revealed no significant changes. Pedagogical dynamics also affect students’ attitudes toward chemistry, so we undertook interviews to investigate the project’s impact on the pedagogical practices of the nine participating teachers. The results suggest that activities developed within the PVC project were formative for the teachers, allowing them to reflect on their practices and promoting an interdisciplinary approach to the topics addressed, in addition to enabling students to use knowledge in different and new perspectives. Moreover, through the development of pedagogical resources and training within this project, teachers recognized that they would continue this experience.

ABSTRACT: While students’ difficulties in constructing scientific arguments have been studied, research on developing the quality of students’ scientific arguments through the implementation of instructional interventions is limited. The present study aims to examine the effects of an instructional intervention for Ohm’s Law, which was designed on a teaching science as practices approach, on the development of the structure of students’ written scientific arguments. Instructional material was constructed for teaching Ohm’s Law and was implemented to 14-year-old students. The research data included students’ written answers (arguments) put down on worksheets during the instructional intervention, as well as students’ answers (arguments) to a questionnaire they were provided with before and after the instructional intervention. Data analysis showed that the instructional intervention contributed to developing the structure of students’ written scientific arguments. The study concludes with a discussion on the results and proposals for further research.
Application of Constructivist Teaching Approach in Introducing New Environmental Concepts to Young Elementary Students in the Philippines: A Small Class Sized Experience from Slime Moulds Modeling
Interdisciplinary Journal of Environmental and Science Education, 2020, 16(2), e2214, https://doi.org/10.29333/ijese/7818
ABSTRACT: The traditional elementary science education setting in the Philippines mainly focuses on using macro-organisms as a biological model. To introduce the fundamental environmental concepts of microbial predation and other related environmental concepts such as decomposition, nutrient cycling and species interaction to the young elementary Filipino students, an initial pilot study was conducted in a small class-sized setting of one international school in the Philippines. Our goal was to (i) design an activity-based teaching program utilizing the constructivist 5E (engage, explore, explain, elaborate and evaluate) method using solely slime moulds as an example organism and (ii) obtain the impression of the students regarding the activity-based teaching program. A purposive sampling size with a total of 45 number of students aging from 10-12 years old were divided into control (16) and experimental (29) groups. Likert scale survey was also given to the student experimental group to assess their overall impression about the newly developed teaching program. Significant differences on test scores between the control and experimental group and the high priority mean scores given by the experimental group points out the effective facilitation of the program. Hence, innovations in teaching pedagogies for difficult science concepts such as the development of the Slimy Business teaching program improves not only the learning quality of the young learners but as well as their environmental appreciation. Applying such novel teaching approach in the conservative Philippine elementary schools is recommended.
