Existing research on "school effectiveness" indicates that differences at the school level contribute significantly towards variation in student outcomes; however, less is known about the effectiveness of schooling in low- and middle-income countries (LMICs). This paper addresses this gap using quantitative analysis of data from two…

The purpose of this publication is to bring attention to some physics problems whose answers seem to be paradoxical and, at first glance, do not agree with a limiting case check. Solving a problem on the motion of a system consisting of two masses and a spring, it is natural to examine the answer by considering a case when a spring constant is…

Suppression effects in multiple linear regression are one of the most elusive phenomena in the educational and psychological measurement literature. The question is, How can including a variable, which is completely unrelated to the criterion variable, in regression models significantly increase the predictive power of the regression models? In…

Conceptual frameworks for Leader and Leadership Education and Development guide the curriculum and assessment of students, faculty, and programs. This commentary defines leader and leadership and presents a leadership conceptual framework that includes four 'C' elements (FourCe) -- Character, Competence, Context, and Communication -- across four…

Purpose: This study aims to better understand entrepreneurial learning in the context of venture acceleration programs. Design/methodology/approach: A qualitative research strategy was used based on multiple in-depth interviews with 21 lead entrepreneurs complemented with participatory observations and secondary sources. The data were inductively…

This qualitative case study of emergent practices in a multi-paradigmatic field at one department in Norway explores how performance metrics in science intra-act with staff composition and resource allocation, potentially affecting paradigm trends. Inspired by agential realism, we discuss four key metrics as the material core of an assemblage…

Automobile Insurance fraud costs the insurance industry billions of dollars annually. This case study addresses claim fraud based on data extracted from Alpha Insurance's automobile claim database. Students are provided the business problem and data sets. Initially, the students are required to develop their hypotheses and analyze the data. This…

The curse of dimensionality, which has been widely studied in statistics and machine learning, occurs when additional features cause the size of the feature space to grow so quickly that learning classification rules becomes increasingly difficult. How do people overcome the curse of dimensionality when acquiring real-world categories that have…

Purpose: This paper aims to clarify the term "tacit knowledge" and suggests the "onion model" as a way to explore conceptually linked layers of tacit knowledge. The model allows the application of different methodologies to elicit tacit knowledge in each layer, the ability to infer tacit knowledge in other layers from tacit…

When considering science education within the makerspace (engineering workshop) context, insufficient attention may be paid to the cultural models organising the learning activity in such spaces. Too often, learning is imagined to be orchestrated by instructors, and students are supposed to passively respond to activities and events planned on…

One of the aims of the current study is to specify the model providing the best fit to the data among the exploratory, the bifactor exploratory and the confirmatory structural equation models. The study compares the three models based on the model data fit statistics and item parameter estimations (factor loadings, cross-loadings, factor…

Modeling within-person change over time and between-person differences in change over time is a primary goal in prevention science. When modeling change in an observed score over time with multilevel or structural equation modeling approaches, each observed score counts toward the estimation of model parameters equally. However, observed scores…

Current literature lacks explication of how traditional grounded theory and mixed methods--grounded theory (MM-GT) are similar/different and specific explication of how to construct MM-GT designs--our purpose is to do this. We illustrate the design process using a published study. Exploratory Phase 1 involves creation of a formative-theoretical…

The impact of the COVID-19 global pandemic on schools was massive and unprecedented. Many schools were forced to close, and teachers were forced to deliver their instruction online with a very short notice. To assist K-12 teachers to teach remotely, a simple instructional design model, CAFE (Content, Activities, Facilitation, & Evaluation),…

The purpose of the study was to examine the causal relationship between teachers' emotional intelligence, job satisfaction, professional identity, and work engagement. And to achieve this purpose, a questionnaire consisting of four scales was administered to 260 teachers selected from the Adentan Municipal in the Greater Accra Region. Exploratory…
