Enhancing scientific creativity through an inquiry-based teaching approach in secondary science classrooms

ABSTRACT The purpose of this study was to explore the impact of inquiry-based teaching on students’ scientific creativity. Using a quasi-experimental design in a Chinese secondary school, the study compared intervention students (N = 102) and control students (N = 245), employing pre- and post-assessments with the ‘Comprehensive Scientific Creativity’ instrument. The intervention involved a biology teacher taking five inquiry-based teaching lessons over a period of two months in each of three 10th-grade classes. Compared to the control group, the intervention group showed statistically significant enhancements in their creativity, specifically in their divergent thinking and convergent thinking, but no difference in their attainment scores or motivation in scientific creativity. The results from the control group suggested that the educational activities they routinely experience may hinder the development of students’ divergent and convergent thinking. Observations of the lessons and interviews with the teacher and students highlighted the challenges of implementing more inquiry-based teaching in upper secondary science lessons in China. These findings provide science educators with inquiry-based teaching strategies for fostering scientific creativity among upper secondary school students, and underscore the need for future research to address implementation challenges associated with inquiry-based teaching.

The implication section delineates steps that can be taken toward strengthening science education within Head Start settings along with support that can be provided to teachers.

Evaluation of students’ digital literacy through an immersive university-high school collaboration

IntroductionRecent efforts including the U.S. Department of Education’s Raise the Bar: STEM Excellence for All Students, designed to strengthen Science, Technology, Engineering and Mathematics (STEM) education, typify the development of effective outreach programs implemented in high school settings to increase STEM achievement and literacy and to promote future careers in STEM. Specifically, artificial intelligence (AI) and machine learning (ML) are topics of great importance and interest but are often reserved for higher-level education. Introductions of complex subjects in high school promotes student efficacy, enthusiasm, and skill-development for STEM careers. Establishing strong partnerships between universities and high schools is mutually beneficial for the professional development of students, teachers, and professors. In this paper, we detail immersive outreach efforts and their effectiveness in a high school setting.MethodsFrom Spring 2021 to Spring 2024, we conducted eight data-science and analysis-coding style workshops along with two data science units, with 302 students participating in the data science workshops and 82 students in the data science units. All students who participated in the data science lessons completed a comprehensive final project. Surveys measuring knowledge and appeal to data science and coding were conducted both retrospectively and prospectively, before and after each workshop and the data science units. A 1 year follow up survey was conducted for students in the 2023 data science lessons (n = 23).ResultsOverall, average student interest significantly increased from 2.72 ± 1.08/5.0 (n = 205) to 3.15 ± 1.18/5.0 (n = 181, p = 0.001) during the data science workshops, while 70% of students expressed desire to continue with coding. Interest modestly increased in the data science lessons from 3.15 ± 0.65/4.0 to 3.17 ± 0.77/4.0 (n = 82, p = 0.8571), while knowledge significantly increased from 64.16% to 88.5% (% correct out of six questions) in the 2023 data science lessons and from 52.62% to 60.79% (% correct out of 29 questions) in the 2024 data science lessons.DiscussionIncreasing STEM exposure through outreach programs and a modified curriculum can positively alter students’ career trajectory and prepare them for the evolving technologically advanced world and the careers within it.

Ai] Explore!: An Educational Game for Developing Programming Skills and Algorithmic Thinking

The game [ai] explore! was developed to introduce the algorithm behind the popular science exhibition. The idea behind the [ai] explore! exhibition was to show the application of mathematics and computer science in solving real engineering problems by creating the exhibit using the mathematical algorithm Heat Equation Driven Area Coverage (HEDAC). The algorithm is based on scientific research and has many applications: exploration and search in unknown space, painting, planning agricultural spraying, scanning 3D objects, etc. The exhibits show the process by which the algorithm paints objects with a virtual brush and explores their shape. By surveying the high school students, it was shown that new mathematical and engineering results can be explained and turned into a playable game. After playing the game, students respond positively to the game presented and state that they have a good understanding of the HEDAC algorithm presented and how it works. This motivated us to investigate [ai] explore! as an educational game for teaching mathematics and computer science. The aim of the research described in this paper is to investigate the potential of the developed game as an educational game. The game-based learning (GBL) approach is increasingly used to increase student motivation and engagement in STEM lessons. The main research question is: How do primary school teachers and students perceive the usefulness of the game [ai] explore! in supporting teaching and learning of computer science concepts? We have developed and implemented teaching scenarios on how the game [ai] explore! can be used as an educational game in computer science lessons. We show that the game has great potential to teach primary school students programming. In addition, the game promotes algorithmic thinking and computational thinking skills in general, which are valuable not only in computer science but also in other fields such as mathematics, where a systematic and analytical approach to problem-solving is required.

Exploring the intersection of disasters and science education with preservice science teachers through a disaster case study

AbstractModern society is under increasing threats of natural and technological disasters, which involve complex interactions among science, technology and social structures. Although a scientific understanding of disasters is an immediate global issue, there is limited discussion about how disasters can relate to science education. To address this gap, we report findings from a research study to support preservice science teachers’ learning about disasters and its relevance to science education. Fifteen preservice science teachers participated in a six-hour workshop focused on the scientific and sociotechnical aspects of the humidifier disinfectant disaster, which caused severe lung injuries to half a million people in South Korea. The study aim was to identify preservice science teachers’ perceptions about how disasters can be incorporated into science teaching. The participants were engaged in a series of group activities using the official investigation report, followed by a discussion on the aspects of science, technology, and society that unfolded in the disaster. Our analysis suggested that the participants were able to discover important aspects of the mutual relationship between science and disasters, and propose various cognitive, attitudinal, and functional aims that could be pursued by embedding disasters in science lessons. The lesson plans showed that the participants were able to suggest how to use disasters in science lessons and leverage diverse teaching methods to achieve their lesson goals. However, the shift in their perceptions before and after the workshop was limited. We argue that support is necessary for preservice science teachers to incorporate disasters into the science classroom, by providing more time and resources and lowering the barriers related to the political and traumatic aspects of disasters.

The purpose of this study is to provide a description of the results of observations on the children of Malaysian migrant workers, especially about the enthusiasm or enthusiasm for learning children not only learning about understanding social sciences but one of them is learning religious science through religious science lessons and forms of application in the form of daily prayers, prayer readings, recitations and da'wah practices in the form of lectures. This material not only conveys the knowledge but also in practice and application as well as the way of delivery and good and correct lecture techniques, besides that also with lectures children can learn public speaking, speaking in public with good and directed conduct. Indonesia's children are future leaders and future generations of the Indonesia nation for the next 10 years, therefore the position of the young generation of Indonesia's children is very much needed. The enthusiasm for learning children in the Sungai Buloh area of Selangor has a very extraordinary spirit of learning. Most of the residents of the community in the Sungai Buloh Selangor area are Indonesia citizens who have lived in Malaysia, so there are quite a lot of children aged 7-13 years who are in elementary school. The Sungai Buloh Learning Studio is one of the main avenues for children of migrant workers to learn social and religious sciences, most of the people in the Sungai Buloh area of Selangor lack access to education due to their incomplete documents so that it is difficult for children to continue to public schools in Kuala Lumpur, this is one of the things that is worrisome because of the lack of access to education for the children of Indonesia migrant workers who are domiciled in the Sungai Buloh region of Selangor, Malaysia. With the enthusiasm of good children to learn but hindered by their incomplete documents, access to education for migrant workers living in the Sungai Buloh Selanggor area, Malaysia is quite difficult.

Perancangan Video Pembelajaran Animasi 2D Mata Pelajaran IPA Proses Fotosintesis di Sekolah Dasar Negeri 04 Sukoharjo

As time goes by, technology is developing very rapidly, especially in education, technology can be used to support learning. For example, at SDN 04 Sukoharjo, the author found a problem or obstacle that in science learning, photosynthesis material still uses the lecture method, using LKS books, so it is still monotonous, making students bored and not interested, because photosynthesis material is a biological process that cannot be seen directly. Therefore, researchers utilized technology, especially in multimedia, to create 2D animated learning videos of the photosynthesis process. The research method uses the ADDIE method, namely (Analysis, Design, Development, Implementation, and Evaluation). The final result of this research is a 2D animation learning video of the science lesson process of photosynthesis.

Distinct functional connectivity patterns during naturalistic learning by adolescent first versus second language speakers

Spoken lessons (lectures) are commonly used in schools as a medium for conveying educational content. In adolescence, experience-expectant maturation of language and cognitive systems supports learning; however, little is known about whether or how learners' language experiences interact with this integration process during learning. We examined functional connectivity using fMRI in 38 Spanish–English bilingual (L1-Spanish) and English monolingual (L1-English) adolescents during a naturalistic science video lesson in English. Seed analyses including the left inferior frontal gyrus (pars opercularis) and posterior middle temporal gyrus showed that L1-Spanish adolescents, when learning in their second language (L2), displayed widespread bilateral functional connectivity throughout the cortex while L1-English adolescents displayed mostly left-lateralized connectivity with core language regions over the course of the science lesson. Furthermore, we identified functional seed connectivity associated with better learning outcomes for adolescents with diverse language backgrounds. Importantly, functional connectivity patterns in L1-Spanish adolescents while learning in English also correlate with their Spanish cloze reading. Findings suggest that functional networks associated with higher-order language processing and cognitive control are differentially engaged for L1 vs. L2 speakers while learning new information through spoken language.
