Abstract

This study investigates the impact of integrated teaching methods on high school students’ ability to evaluate physical experiments, with a particular emphasis on metacognitive awareness and scientific reasoning. Drawing on a mixed-methods approach, the action research explores how combining inquiry-based learning, collaborative problem-solving, and reflective assessment strategies enhances students’ capacity to critically analyse experimental design, data interpretation, and procedural validity. The study addresses three core questions: (1) How do integrated teaching methods influence students’ ability to evaluate physical experiments? (2) Which components of integrated teaching are most effective? (3) What changes occur in students’ metacognitive awareness and scientific reasoning?

Preliminary findings suggest that students exposed to integrated instruction demonstrate improved analytical precision, greater self-regulation, and deeper conceptual understanding. These results underscore the value of holistic pedagogical frameworks in cultivating scientific literacy and evaluative competence among secondary learners.

Introduction

In contemporary science education, the ability to critically evaluate physical experiments is a cornerstone of scientific literacy. High school students often engage in laboratory activities that require not only procedural execution but also thoughtful analysis of experimental design, data reliability, and conceptual validity. 

Integrated teaching methods—such as inquiry-based learning, collaborative problem-solving, and reflective assessment—offer a promising framework for addressing this gap. By blending conceptual instruction with hands-on experimentation and metacognitive reflection, these approaches aim to deepen students’ understanding of scientific processes and foster higher-order thinking. Such integration encourages learners to question assumptions, identify sources of error, and articulate the reasoning behind their conclusions.

This study explores how integrated teaching methods influence students’ ability to evaluate physical experiments, with particular attention to the development of metacognitive awareness and scientific reasoning. It seeks to identify which components of integration are most effective and how they contribute to meaningful shifts in students’ analytical and reflective capacities. The findings aim to inform curriculum design and pedagogical practice in physics education, ultimately supporting the cultivation of independent, critically minded learners.

 Research objectives

• To develop a replicable framework for physics educators.

Literature review

Evaluating physical experiments is a core skill in science education, encompassing hypothesis formulation, data analysis, error estimation, and critical reflection. However, many students struggle with these tasks due to fragmented instruction and limited opportunities for inquiry-based learning.

Traditional physics teaching often emphasizes procedural knowledge over conceptual understanding. Studies show that students frequently follow lab instructions mechanically without grasping the underlying principles or evaluating the reliability of their results (Pols & Dekkers, 2024). This leads to poor development of science process skills (SPS), including observation, inference, and interpretation (Tan, Yangco, & Que, 2020; Yildiz & Kaya, 2023).

Integrated teaching methods—such as STEM integration, guided inquiry, and simulation-based learning—have shown promise in enhancing students’ experimental reasoning and evaluation skills. Ningtyas et al. (2024) conducted a systematic review showing that integrated STEM approaches improve students’ analytical thinking, problem-solving, and experimental design capabilities. Chengere et al. (2025) demonstrated that inquiry-based lab activities significantly enhance students’ SPS, particularly in hypothesis testing and data interpretation. Banda & Nzabahimana (2021) reviewed 31 studies on PhET simulations and found that digital tools improve conceptual understanding and help students visualize abstract phenomena, which supports better evaluation of experimental outcomes.

Several educational theories underpin integrated teaching methods. Constructivism emphasizes active learning where students build knowledge through experience and reflection (Taber, 2024; McLeod, 2025). Bloom’s Taxonomy encourages higher-order thinking skills such as analysis and evaluation, which are essential for experiment assessment (Bloom, 1956; Ruhl, 2025). Kolb’s Experiential Learning Cycle highlights the importance of reflective observation and abstract conceptualization in learning from experiments (Kolb, 1984; McLeod, 2025).

Action research methodology My research utilizes the qualitative method of research. This research work is the result of a study of the actions taken in the context of my own professional development as a teacher. The research consists of 4 sections: (1) Review of documents and related literature; (2) Action research cycle follows the iterative plan–act–observe–reflect cycle to continuously refine teaching practices. Purpose of action research methodology is to improve students’ evaluative skills in physics experiments while simultaneously developing the teacher’s instructional strategies. (3) Qualitative and quantitative data analysis and (4) Drawing conclusions and findings. The participants of this study consisted of twenty-three (23) 11th-grade students, ages 15-16. The study consists of 2 phases: the first phase covered September until end of October 2025, while the second phase covered November to December 2025. This action research cycle focused on improving students’ ability to evaluate physics experiments through integrated interventions. In the ‘planning stage’, challenges were identified using ESA (external summative assessment) results and lesson observations, revealing weaknesses in recognizing errors and evaluating reliability. Interventions were designed around inquiry-based tasks, collaborative problem-solving, and reflective assessment using rubrics and journal templates. In the ‘acting stage' students engaged in experiments on resistance, acceleration, momentum, and specific heat capacity. Structured worksheets, prompts, simulations, and peer discussions guided systematic data recording, error analysis, and reflection. The teacher facilitated learning while investigating the impact of scaffolding and digital tools. In the ‘observing stage’, evidence from pre/post-tests, journals, rubrics, teacher notes, and interviews showed significant improvement. Students progressed from basic calculations to deeper evaluation, distinguishing error types, proposing corrective strategies, and critically questioning data. Reflective journals highlighted metacognitive growth, while interviews emphasized the value of combining physical experiments with simulations. In the ‘reflecting stage’, quantitative analysis showed rising test scores and rubric ratings, while qualitative analysis revealed a shift from descriptive to evaluative reasoning. Effective practices included structured prompts, peer collaboration, and simulation integration. For the next cycle, modifications aim to further strengthen evaluative reasoning, quantitative reflection, and collaborative critique. Second action research cycle was conducted between November and December 2025. In planning stage, I used the same assessment criteria and self-assessment rubrics, however provided structured and modified journal templates with guiding questions to ensure all students engage in deeper metacognitive reflection. Because in the first cycle categories such as `Reasoning and metacognitive awareness` and `Collaboration and communication` needed improvement.

Findings Here’s a structured triangulation of findings across the three main evidence sources from two action research cycles Metacognitive Growth Student reflective journals, self-assessment rubrics and peer-assessment rubrics show clear shift from descriptive recounting to evaluative reflection. Students identified sources of error (friction, misalignment, sensor delays) and connected them to theory. Teacher observation notes and video recordings confirmed that students verbalized reasoning during debates, corrected misconceptions, and linked anomalies to theoretical principles. Interviews and focus groups students reported greater confidence in identifying errors and valued structured prompts for reflection. Collaborative reasoning and peer learning Student journals & peer rubrics (Table 5) growth in categories like peer reasoning and collaboration/respect. Students increasingly engaged with peer ideas, asked clarifying questions, and gave constructive feedback. Teacher observations documented active debates, peer-to-peer questioning, and collaborative problem-solving. Misconceptions were corrected in real time. Interviews and focus groups students appreciated peer discussions and rubrics as tools for structured collaboration. Conclusion This study found that integrated teaching methods—combining inquiry, collaboration, and reflection—significantly enhanced high school students’ ability to evaluate physical experiments. Inquiry fostered curiosity, collaboration strengthened reasoning, and reflection deepened metacognitive awareness. Among the components, reflective journals, peer-evaluation rubrics, and scaffolded experimental tasks proved most effective in promoting evaluative competence and scientific reasoning. Students progressed from simple descriptions to critical reflection, questioning assumptions, distinguishing errors, and confidently interpreting outcomes. Overall, integrated approaches cultivated scientific literacy, self-regulation, and deeper conceptual understanding, showing that holistic pedagogical frameworks are essential for preparing learners to engage rigorously and reflectively in scientific inquiry
