OpenAlex is a new, fully-open scientific knowledge graph (SKG), launched to replace the discontinued Microsoft Academic Graph (MAG). It contains metadata for 209M works (journal articles, books, etc); 2013M disambiguated authors; 124k venues (places that host works, such as journals and online repositories); 109k institutions; and 65k Wikidata concepts (linked to works via an automated hierarchical multi-tag classifier). The dataset is fully and freely available via a web-based GUI, a full...

Existing literature shows varying impacts of Information and Communication Technology (ICT) on learning outcomes depending on the type and quality of technology used. However, current research on the optimal level of ICT use for the cognitive development of students is scarce and has remained country-specific, primarily focusing on developed economies. This paper undertakes a cross-country comparison across 79 nations, investigating ICT use and its association with cognitive gain patterns as...

Background It is believed that poor classroom acoustics leads to lower levels of student learning and exposes teachers vocal folds to greater physical wear and tear. Objective This study sought to compare the quality of life by World Health Organization (whoqol-bref) questionnaire of 61 teachers working at schools with different acoustic conditions. Methods This paper reports on a descriptive exploratory study aimed at ascertaining the following: (1) outdoor sound pressure levels in the...

Motivated by the fact that many relations cross the sentence boundary, there has been increasing interest in document-level relation extraction (DocRE). DocRE requires integrating information within and across sentences, capturing complex interactions between mentions of entities. Most existing methods are pipeline-based, requiring entities as input. However, jointly learning to extract entities and relations can improve performance and be more efficient due to shared parameters and training...

Existing knowledge-grounded dialogue systems typically use finetuned versions of a pretrained language model (LM) and large-scale knowledge bases. These models typically fail to generalize on topics outside of the knowledge base, and require maintaining separate potentially large checkpoints each time finetuning is needed. In this paper, we aim to address these limitations by leveraging the inherent knowledge stored in the pretrained LM as well as its powerful generation ability. We propose...

The purpose of this study was to establish challenges and experiences faced by student teachers during teaching practice in Zambia. The study employed the concurrent embedded design. Data was collected from 280 respondents including 200 student teachers, 30 host school deputy head teachers and 50 lecturers. The study employed a questionnaire, focus group discussion and an interview to collect data from the respondents. The study established some challenges which can serve as learning points...

The study adopted a descriptive survey design to examine the perception of secondary school science and mathematics teachers on professional development in Zamfara State, Nigeria. The population of the study consisted of all Science and Mathematics teachers in public secondary schools in Zamfara State. A sample of 217 respondents were drawn through purposive and simple random sampling techniques. Data were collected using a structured questionnaire. Four research questions and two null...

The unprecedented outbreak of the Corona Virus Disease 2019 (COVID-19) pandemic has seriously affected numerous countries in the world from various aspects such as education, economy, social security, public health, etc. Most governments have made great efforts to control the spread of COVID-19, e.g., locking down hard-hit cities and advocating masks for the population. However, some countries and regions have relatively poor medical conditions in terms of insufficient medical equipment,...

At EdTech Hub, we’ve been reflecting on how coloniality is embedded in the work we do: from the colonial roots of the international development sector, to colonial practices embedded in research methods, to “core-to-periphery” design and deployment of EdTech interventions.

The anthology presents current approaches to digitally supported professional learning. The articles provide insights into the dynamic development of the interfaces between gainful employment and vocational training and further education in the context of digitization of work and learning aids. The volume is thus connected to the publication “Berufsbildung am Bau digital” (edited by Bernd Mahrin and Johannes Meyser), which was published in 2019 by the University Press of the Technische...

We introduce GPT-NeoX-20B, a 20 billion parameter autoregressive language model trained on the Pile, whose weights will be made freely and openly available to the public through a permissive license. It is, to the best of our knowledge, the largest dense autoregressive model that has publicly available weights at the time of submission. In this work, we describe \model{}'s architecture and training and evaluate its performance on a range of language-understanding, mathematics, and...

The traditional “one size fits all” education system has been largely criticized in recent years on the ground of its lacking the capacity to meet individual student needs. Global education systems are leaning towards a more personalized, student-centered approach. Innovations like Big Data, Machine Learning, and Artificial Intelligence (AI) have given the modern-day technology to accommodate the distinctive features of human beings - smart machines and computers have been built to...
