Title: Relationships between high school students' learning interest, learning motivation, and ocean literacy: a longitudinal study Authors: Tsai, Liang-Ting; Chang, Cheng-Chieh Abstract: This study investigated the trends and correlations between ocean literacy (OL), marine science learning interest (MSLI), and marine science learning motivation (MSLM) in Taiwanese high school students in a three-wave longitudinal survey, with an OL scale used to assess students' MSLI and MSLM. A total of 428 valid responses were collected. The results indicated that the students' OL decreased by the second survey but slightly increased by the third. The MSLM scores exhibited an upward trend, whereas MSLI remained unchanged. A cross-lagged analysis revealed a consistently positive correlation between OL and MSLM across all three waves. Moreover, significant positive correlations between OL and MSLI and between earlier OL levels and later MSLI were observed, indicating OL plays a critical role in fostering MSLI. This study elucidates the associations between OL and MSLI and proposes directions for enhancing future OL education and research.

THE CRITICAL YET OVERLOOKED SPATIAL COMPETENCE IN LEARNING SEMANTIC SPATIAL INFORMATION IN PICTURES

Title: THE CRITICAL YET OVERLOOKED SPATIAL COMPETENCE IN LEARNING SEMANTIC SPATIAL INFORMATION IN PICTURES Authors: Chen, Yi-Chun Abstract: 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 between spatial ability and science achievement were tested. A mixed-methods design was used. Forty university students participated. Mental rotation and astronomical drawing tests were used to evaluate their general spatial ability and science achievement. The domain-specific spatial knowledge used in solving astronomical drawing tests was ascertained via interviews and analyzed, with results presented as static- type semantic spatial propositions and dynamic-type spatial skills. The results demonstrated an overlap between general spatial ability and domain-specific spatial knowledge, challenging the traditional dichotomy between them. Furthermore, domain-specific spatial knowledge fully mediated the relationship between general spatial ability and science achievement. These findings have significant implications for astronomy education, highlighting the importance of domain-specific spatial competence over general ability in solving domain problems and underscoring the need for explicit instruction in the decoding of semantic spatial information in pictorial representations, which is often overlooked in studies focusing on spatial skills training or the surface characteristics of scientific representations.

Title: Flipped classroom with case-based learning for improving preservice teachers' classroom management learning outcomes Authors: Chen, Chi Yuan Abstract: This study explored the effects of combining the flipped classroom with case-based learning in a classroom management course (n = 73 pre-service teachers). We adopted a mixed-methods design to collect data. The results revealed improvements in learning outcomes and perceptions, suggesting considerable advantages of the innovative teaching model. Using preclass videos and group discussions enhanced pre-service teachers' problemsolving skills and knowledge application. Reflections and multiple perspectives helped them develop a deeper understanding of topics. Moreover, the identified factors contributing to learning success include the preparedness of preservice teachers to engage with materials before class, effective discussion facilitation, and group dynamics.

Novel isolates of hydrogen-oxidizing chemolithoautotrophic Sulfurospirillum provide insight to the functions and adaptation mechanisms of Campylobacteria in shallow-water hydrothermal vents

Title: Novel isolates of hydrogen-oxidizing chemolithoautotrophic Sulfurospirillum provide insight to the functions and adaptation mechanisms of Campylobacteria in shallow-water hydrothermal vents Authors: Wang, Li; Cheng, Xinyi; Guo, Yizhe; Cao, Junwei; Sun, Mingye; Hwang, Jiang-Shiou; Liu, Rulong; Fang, Jiasong Abstract: Enhancing the availability of representative isolates from hydrothermal vents (HTVs) is imperative for comprehending the microbial processes that propel the vent ecosystem. In recent years, Campylobacteria have emerged as the predominant and ubiquitous taxon across both shallow and deep-sea vent systems. Nevertheless, only a few isolates have been cultured, primarily originating from deep-sea HTVs. Presently, no cultivable isolates of Campylobacteria are accessible in shallow water vent systems (<200 m), which exhibit markedly distinct environmental conditions from their deep-sea counterparts. In this study, we enriched a novel isolate (genus Sulfurospirillum, Campylobacteria) from shallow-water HTVs of Kueishan Island. Genomic and physiological analysis revealed that this novel Campylobacteria species grows on a variety of substrate and carbon/energy sources. The pan-genome and phenotypic comparisons with 12 previously isolated Sulfurospirillum species from different environments supported the identification of functional features in Sulfurospirillum genomes crucial for adaptation to vent environments, such as sulfur oxidation, carbon fixation, biofilm formation, and benzoate/toluene degradation, as well as diverse genes related with signal transportation. To conclude, the metabolic characteristics of this novel Campylobacteria augment our understanding of Campylobacteria spanning from deep-sea to shallow-water vent systems.
