This dissertation examined the relationship between elementary school science teachers' epistemic orientation and classroom learning environment type--generative or replicative--they established for science knowledge development. Drawing on the theory of epistemological development and understanding, the influence of teacher epistemic beliefs on…

This study examined the impact of spatial ability on science achievement by distinguishing between domain-general and domain-specific spatial abilities, focusing on their relationship with the conceptual understanding of the apparent path of the sun. Additionally, the mediating effects of domain-specific spatial knowledge on the relationships…

The essence of university courses lies in their scientific rigor, while the enjoyment of learning serves as a motivation. In this regard, we have developed a comprehensive experiment project by incorporating dithienylethene-based photochromic units into sensitizers for renewable energy, specifically dye-sensitized solar cells, through organic…

With the increase of waste paper, environmental pollution and atmospheric impact have become global problems. The cellulose contained in waste paper has the advantages of being renewable and biodegradable and can be applied to many fields to achieve sustainable development. At present, thermal management materials, as a new type of material, have…

The Bee the CURE is a novel course-based undergraduate research experience (CURE) that engages introductory biology students in DNA barcoding (DNA extraction, amplification, and bioinformatics) in partnership with the Tucson Bee Collaborative and the University of Arizona. The first iteration of this CURE taught at Pima Community College (PCC)…

The incorporation of socioscientific issues into science teaching to promote students' scientific literacy may require that science teachers reconsider and transform their teaching practices. This study examines the knowledge and considerations involved when two teachers incorporated socioscientific issues into their teaching, with the aim of…

Many scientific concepts and theorems are often abstract and challenging to relate to real-life problems, making it difficult for students to grasp them. Therefore, some researchers have attempted to enhance students' understanding by employing a contextual learning approach, which allows students to apply scientific knowledge to real situations…

This study explored a middle school science teacher's curricular sensemaking in interaction with their use of an educative storyline curriculum, aligned to the Next Generation Science Standards, that was intentionally designed for more opportunities for students' scientific sensemaking. Using a phenomenological case study methodology, we examined…

Background: Integrated science is a ubiquitous school subject that is an amalgamation of science disciplines; its teaching allows topics to be sequenced in any order and given various degrees of coverage and emphasis in the classroom. Ensuring canonical coherence, which is the logical organization of subject matter for effective instruction is…

We designed and evaluated a student laboratory workshop on plant-based vaccines against the SARS-CoV-2 virus. The workshop focused on hands-on laboratory techniques, including DNA extraction from rice seeds, where the recombinant protein was produced, detection of the transgene, and basic concepts on how vaccines work in the human body to offer…

The switch to online learning required a creative solution to allow for the experiential learning outcomes of the program to be satisfied when access to physical spaces and equipment was restricted. This paper describes a collaborative process between technical and support staff as well as research and teaching faculty that led to the creation of…

Science teachers struggle to implement and sustain new curricular ideas from professional development (PD) experiences. These PD opportunities are crucial for enacting real-world changes to teaching practice and address pressing global challenges, such as the teaching and learning of socioscientific topics nested in school communities.…

Language is a fundamental tool for learning science. This study highlights the importance of teacher knowledge in utilising language as a tool for knowledge generation in the classrooms. This case study examines elementary teachers' development of declarative, procedural, and epistemic knowledge related to using language, particularly focusing on…

In 2014, the NIH Diversity Program Consortium (DPC) launched an initiative to implement and evaluate novel interventions at a variety of academic institutions across the country to engage undergraduate students from diverse backgrounds in biomedically-related research. The local intervention examined in the current study provides Critical Race…

This study explored the impact of authentic out-of-school learning on students' beliefs about their science learning efficacy and career aspirations. The learning activity, designed following an authentic learning framework, was led by research scientists. We examined how students' emotions, induced in an authentic scientific activity, mediated…
