1. Introduction

In the dynamic realm of science education, elucidating the intricate dynamics of effective teaching is imperative for cultivating meaningful learning experiences. Despite a plethora of studies delving into individual dimensions of science teaching, there exists a notable gap in the literature regarding a comprehensive model that systematically examines the interrelationships among critical perspectives, theoretical foundations, practical teaching, technology integration, assessment and feedback, and hands-on practices within science education ¹. This research seeks to address this gap by undertaking a meticulous examination of these dimensions, framed by the constructivist theory and scrutinized through the discerning lenses of experienced science educators.

In the existing body of literature on science education, an apparent void emerges when it comes to comprehensive models that elucidate the intricate interplay among critical perspectives, theoretical foundations, practical teaching, technology integration, assessment and feedback, and hands-on practices within the context of science teaching ^{2, 3, 4, 5}. While numerous studies have independently examined these dimensions, there is a discernible lack of research that systematically models the relationships among them. The absence of such comprehensive modeling impedes our ability to grasp the synergistic effects and interdependencies that characterize effective science instruction ^{6, 7, 8, 9, 10}. This research endeavors to fill this critical gap by not only acknowledging the importance of each dimension but also by providing a holistic and empirically substantiated structural equation model that captures the complex web of interactions among these facets. The endeavor is rooted in the understanding that an integrated model holds the potential to revolutionize pedagogical approaches in science education, offering educators and researchers a nuanced framework to enhance instructional practices and ultimately elevate the quality of science learning experiences for students ^{11, 12, 13, 14, 15}.

Grounded in the constructivist philosophy, which posits learning as an active process of knowledge construction, the identified dimensions align with constructivist principles in science education. Critical perspectives foster an environment conducive to questioning and critical analysis, theoretical foundations provide the cognitive framework for knowledge construction, practical teaching methods promote active student engagement, technology integration enhances interactive learning experiences, assessments become formative tools for ongoing understanding, and hands-on practices exemplify the application of theoretical concepts in authentic contexts ^{1, 16, 17, 18, 19}. To rigorously explore the intricate relationships among these dimensions, this research employs a Structural Equation Modeling (SEM) approach. SEM offers a robust analytical framework, allowing for the systematic modeling of direct and indirect relationships between critical perspectives, theoretical foundations, practical teaching, technology integration, assessment and feedback, and hands-on practices. By leveraging SEM methodology, this research seeks to not only unveil the underlying structures and dynamics influencing effective science instruction within the constructivist paradigm but also quantitatively assess the strength and significance of these relationships.

The crux is: this study contributes to the scientific literature by presenting a validated structural equation model that transcends theoretical conjecture, providing empirical insights into the complexities of science education. Rooted in both constructivist principles and the methodological rigor of SEM, the research aims to unravel the intricate tapestry of effective science instruction. By doing so, it strives to advance our understanding of the nuanced interplay among critical perspectives, theoretical foundations, practical teaching, technology integration, assessment and feedback, and hands-on practices, ultimately informing the cultivation of interactive, participatory, and student-centered learning environments in science education ^{20, 21, 22, 23}.

This collective affirmation across all dimensions signifies a comprehensive approach to science teaching in the locale of this study. The findings suggest heightened awareness among educators on the importance of each dimension and proactive implementation in instructional practices. This consensus among teacher-respondents provides a strong foundation for subsequent structural equation modeling analysis, indicating an environment suitable for exploring interrelationships among these dimensions and their collective impact on effective science instruction ^{24, 25, 26, 27, 28}. This research presents an opportunity to delve deeper into the connections and dynamics among these dimensions in a context where they are widely practiced, contributing to the broader discourse on science education.

2. Structural Equation Modeling on the Dimensions of Science Teaching

Presented in Table 3 are the estimates and outcomes of the proposed relationships in the model as shown in Figure 1. The parameter estimates based on the beta coefficient and p-value from the result of SEM analysis reveals that 13 out of the 15 hypotheses had direct affect in between select constructs of the dimensions of science teaching in the locale of the study.

In terms of the inter-relationship of the seven constructs, two have significant large effects as found based on the SEM analysis. Conceptual Perspectives (CP) posted a large (f²=.739) direct effect on Theoretical Perspectives (TP) (p-value=<.001) while TP posted the same, f²=.369, on Assessment and Feedback (AF) (p-value=<.001). On the other hand, CP posted moderate direct effect along PTE, UT, and HOP, f² values of .178, .238, and .198, and p-values of <.001, <.001, .019, respectively; TP posted similar moderate direct effect on PTE and UT, f² values of .155 and .269, and p-values of .001 and <.001, respectively; PTE posted similar moderate direct effect on AF and HOP, f² values of .193 and .329, and p-values of <.001, respectively; UT posted moderate direct effect on PTE and AF, f² values of .319 and .193, and p-values of <.001; AF posted moderate direct effect on HOP with f² value of .341 and p-value of <.001; UT posted small direct effect on HOP with f² value of .147 and p-value of .003. The SEM analysis revealed significant direct effects among the six dimensions of science teaching. These findings post significant implications for educators and academic planners, suggesting the need to develop policies and other interventions to bolster the status of science teaching across all level especially that the Philippines lagged behind in the recent world ranking in science like the PISA.

4. Proposed Plan to Bolster Science Education in the Elementary, Secondary, and Tertiary

The proposition of six key strategies for enhancing science education demands a critical examination of each element. Firstly, the call for the "Recognition and Reinforcement of Effective Practices" is commendable but necessitates moving beyond symbolic gestures. While events like an Open House and Awards Day are important, a sustained culture of excellence requires tangible, continuous recognition through avenues such as professional development opportunities or mentorship initiatives. The "Professional Development Program" is a strategic move, but its effectiveness hinges on the ongoing evaluation of content relevance and practical applicability. Ensuring a balance between theoretical knowledge and practical skills is crucial, necessitating continuous feedback from participants.

Collaborative curriculum designs advocating for the integration of Conceptual Perspectives (CP) and Theoretical Perspectives (TP) through interdisciplinary approaches offer promise. However, a critical analysis is essential to ensure the feasibility and adaptability of such approaches. Consideration of available resources, faculty expertise, and the local educational context is paramount to avoid implementation challenges. The "Policy Formulation for Science Education Improvement" is a significant step, but policies must be dynamic and responsive. Constant evaluation and adjustment, guided by ongoing feedback, local studies, and international benchmarks, are necessary to address both immediate needs and future trends in science education.

Engaging in "International Benchmarking and Collaboration" presents opportunities, but a nuanced approach is crucial. Critical analysis is needed to contextualize successful practices from other countries, considering the unique challenges and strengths of the local education system. Lastly, the establishment of mechanisms for "Continuous Monitoring and Evaluation" is foundational, yet its effectiveness hinges on robust feedback systems, regular data analysis, and a commitment to act upon findings. The evaluation process should be iterative, allowing for adjustments based on changing needs and circumstances. In essence, each strategy's success lies in its continuous refinement based on ongoing assessment, feedback, and a comprehensive understanding of the local and global landscape of science education.

4. Conclusion
