Context modeling is the keystone to enable the intelligent system to adapt its functionalities properly to different situations. As such, a representation mechanism that allows an adequate manipulation of this kind of information is required, and diverse approaches have been introduced; however, what takes more value and is being positioned as a…

This study aims to examine the effect of collaborative supervision approaches and collegial supervision techniques on teacher intensity using performance-based learning in the learning process. In addition, its purpose is also to examine the impact on student learning outcomes. This study was conducted in East Java, Indonesia, with a descriptive…

We have revamped a classic analytical chemistry laboratory experiment, "Determination of an Unknown Acid", to provide students an opportunity to learn about new advances in the material sciences and their applications in analytical chemistry in an effort to reinforce the key concepts of chemical analysis. Specifically, students were…

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…

Existing research studying MOOC learner diversity has mainly taken unidimensional approaches, which have led to partial or inconsistent findings. This paper addresses this issue by proposing a multi-dimensional model that helps to identify and build the personas of key learner subgroups in any given MOOC course. By linking learners' behavioral…

This article critically examines how monitoring strategies currently track progress on country commitments to adult learning and education (ALE). These commitments are laid out in three main international initiatives and policy tools: (1) the Belém Framework for Action (BFA); (2) the 2015 Recommendation on Adult Learning and Education (RALE); and…

This study aimed to explore what kinds of epistemological messages were conveyed through teacher discourse in modeling-based and traditional elementary science classrooms and how teachers framed the two classrooms distinctively through these messages. Data came from two sixth-grade teachers' science classrooms--one characterized as a…

In Physical Education Teacher Education programs, we argue that a focus on fewer models to be taught and learned would provide time for higher competence to be attained by preservice teachers in a curriculum limited in terms of contact hours. During their teacher training, preservice teachers should be given ample opportunities to practice the…

Biochemistry primarily focuses on the non-metal chemical elements carbon, oxygen, nitrogen, hydrogen, sulfur, and phosphorus in the four groups of building blocks (sugars, lipids, amino acids, and nucleotides) and the corresponding macromolecules. However, at least 10 essential chemical elements of life are metals. This article discusses the…

Judges, jurors and other triers of fact often rely upon eyewitness evidence in criminal trials, but eyewitness memory is not always accurate and can sometimes be contaminated. The I-I-Eye is an evidence-based teaching aid designed to improve the evaluation of eyewitness evidence in legal settings. We aimed to further test the I-I-Eye and examine…

Background: Sex education for people with intellectual disability is in its infancy in countries where their sexual expression is still considered a taboo. This study aimed at exploring the experiences of professionals involved in providing sex education to people with intellectual disability across a number of services in a Maltese context.…
