In this paper, we present simple demonstrations aimed at explaining the fundamental principles of the photoacoustic effect. To display the audible phenomenon that occurs as laser radiation gets absorbed by ethene gas, an optical chopper was used to modulate the power of a continuous-wave laser whose beam was directed into a gas. The absorbed…

This paper describes a study that used a novel method to investigate conceptual difficulties with mathematical induction among two groups of undergraduate students: students who had received university-level instruction in formal mathematical induction, and students who had not been exposed to formal mathematical induction at the university level.…

This study is a phenomenological exploration of assessment practices in elementary-level drama education. Through analysis of interviews with fourteen drama educators, it describes how elementary drama teachers conceptualize assessment in theory and practice. Specifically, it discusses teachers' explicit definitions of assessment; the content…

There is a growing need for valid and reliable measures to monitor the efficacy of undergraduate science, technology, engineering, and mathematics (STEM) reform initiatives. The Classroom Observation Protocol for Undergraduate STEM (COPUS) is a widely used tool originally designed to measure the presence of overt instructor and student behaviors.…

In modern Western education, the visual arts have come to hold a problematic position in the school curriculum. Art is often classified by school leaders, students, parents and even teachers as different from other subjects; sometimes viewed as almost magical, enabling students to explore and develop an innate creativity; sometimes simply…

Research-based assessments (RBAs) measure how well a course achieves discipline-specific outcomes. Educators can use outcomes from RBAs to guide instructional choices and to request resources to implement and sustain instructional transformations. One challenge for using RBAs, however, is a lack of comparative data, particularly given the skew in…

This study aimed at determining the category and analyzes the mental models of the students from three senior high school clusters (low, medium, high) on the solubility and solubility product topic, knowing students' opinions on chemistry subject, knowing learning methods and assessment that teacher used in solubility and solubility products…

Purpose: The present study seeks to examine the efficacy of different training modalities on increasing workplace learning, representatives' intent to transfer what they learned into their work, and importantly how training impacts actual work performance. These relationships are tested in the context of a Chinese division of a multinational…

Drawing on critical literacy as a theoretical framework, this paper explores how a children's book writing assignment designed to center the experiences of underrepresented communities in children's literature contributed to shifts in awareness among predominantly White teacher candidates. The study occurred at a large urban university in…

Although Writing Across the Curriculum (WAC) has long focused on incorporating writing and related literacy activities into STEM education, the extent to which these pedagogies are widely used in STEM teaching remains unclear, as does their impact on student course performance, especially for underrepresented and marginalized student groups. Using…

The purpose of this study was to establish the factor structure and dimensionality of the Metacognitive Orientation Learning Environment Scale -- Science (MOLES-S) in the Thai context. The metacognitive orientation of a science classroom learning environment is defined as the extent to which psychosocial conditions that are known to enhance…

The long history of Montessori education in India dates to 1915, and it was expanded through Maria and Mario Montessori's work in India between 1939 to 1946 and 1947 to 1949. The article characterizes a century of Montessori education in India as a series of "adapted, competing, and contested framings" with key disputes over Montessori…

Contribution: In the research presented in this article, a procedure for determining student workload has been designed, tested, and validated. This procedure also makes it possible to analyze how different teaching variables are affected by workload and to visualize the learning environment generated in the course. Background: When the…

Secondary mathematics teachers' use of formative assessments have shown promise for developing models of their students' mathematical thinking and informing their instruction. While the complexities of secondary mathematics teachers' formative assessment practices are often captured in qualitative research, there is a critical need for synthesized…

Comparative interrupted time series (CITS) designs evaluate impact by modeling the relative deviation from trends among a treatment and comparison group after an intervention. The broad applicability of the design means it is widely used in education research. Like all non-experimental evaluation methods however, the internal validity of a given…
