Despite considerable advances in knowledge tracing algorithms, educational technologies that use this technology typically continue to use older algorithms, such as Bayesian Knowledge Tracing. One key reason for this is that contemporary knowledge tracing algorithms primarily infer next-problem correctness in the learning system, but do not…

The study complements previous research on a case study of chemistry lesson plans design and teaching. It has been found that chemistry education in the Gambia has been challenged by ineffective lesson plans design and teaching, and laboratory resources. The consequences have been unsatisfactory learning outcomes. However, what could lead to…

Given pressing enrollment, retention and completion issues at community colleges, the use of data analytic tools has gained more relevance for practitioners and scholars. Among these tools is machine learning, but its use is relatively new to community colleges and institutional research practice. This exploratory qualitative study examined a…

Elementary students demonstrate conflicts when measuring with rulers as well as measuring with discrete units. Their conflicts often lie in their focus on counting tick marks or focusing on the endpoint of objects on rulers or ignoring spaces with discrete units. In this study, we also investigated another area of conflict: students' conceptions…

Access and use of mobile phones by communities in rural areas is a topical issue in different countries. However, there has been limited empirical literature to account for mobile phone use in rural areas for development and lifelong learning. This study employed the data which were collected from 66 phone users in rural areas to report on their…

Many research studies have shown that lower-secondary school students' scientific literacy depends on their understanding of corresponding scientific concepts. Therefore, it is of great significance to model and assess students' conceptual understanding in learning specific scientific concepts, because it can reflect and diagnose students'…

Previous studies highlight the importance of investigate the construction in video-recorded learning situations. The aim of this study is to investigate how video-recordings can be used to enhance pre-service teachers' abilities to identify children's exploration of mathematics in preschools. Even if some previous studies have focused the use of…

The American Society of Civil Engineer's "Body of Knowledge" versions 2 and 3 (BOK2 and BOK3) explicitly describe the knowledge expected in each category (outcome) of those entering the civil engineering profession. The goal of this study was to determine the extent that the BOK2 and BOK3 outcomes align with undergraduate civil…

Evolutionary theory (ET) is the unifying theory of Life Sciences, but it is largely misunderstood and the target of dispute in many countries, mainly because of conflicts with religious beliefs. Brazil is a country with a culture that is deeply rooted belief in God. In this paper, we report a study in Brazil where we applied a 12-question…

Purpose: The purpose of this study is to examine the differences in sustainability knowledge, behaviors and attitudes among college students and to estimate the influence of knowledge of sustainability on students' sustainable behaviors. Design/methodology/approach: A cross-sectional online survey was used to collect quantitative data on…

A fundamental question in numerical development concerns the directional relation between an early-emerging non-verbal approximate number system (ANS) and culturally acquired verbal number and mathematics knowledge. Using path models on longitudinal data collected in preschool children (M[subscript age] = 3.86 years; N = 216; 99 males; 80.8%…

The initial and continuing training of mathematics teachers continues to be one of the most pressing challenges facing the research community in mathematics education. In this regard, various research agendas have been proposed and developed. Among these, two stand out: the characterization and development of (1) didactic and mathematical…

Generalised Joint Hypermobility (GJH) is a heritable disorder of the connective tissue that manifests as extreme range of motion in the joints; it is considered both an asset and health risk to the dancer. Recently, links between GJH, anxiety, emotional and mental wellbeing have been established. The experiences of GJH in professional dance…

Interest in Science, Technology, Engineering and Mathematics (STEM) has gained momentum due to increasing calls for a more STEM-literate society. As teaching integrated STEM poses curricular and pedagogical challenges for most generalist primary teachers, professional development (PD) is essential to support them to develop appropriate knowledge…

The FedEx logo makes clever use of figure-ground ambiguity to create an "invisible" arrow in the background space between "E" and "x". Most designers believe the hidden arrow can convey an unconscious impression of speed and precision about the FedEx brand, which may influence subsequent behavior. To test this…
