Natural science in education can be summarized as a complex system. The professional and methodological task in the teaching of natural sciences is to convey this complexity. The terms and models of graph theory can be used to model the system approach, such as networks. Networks consist of elements and connections between them, which can be well…

In physics education, assessments address various forms of scientific knowledge. Most of the existing test instruments emphasise the assessment of content knowledge. These tests fail to measure the epistemic aspects of science. Thus, assessing epistemic knowledge is a theme that demands investigation. This study applies Rasch analysis to help…

An attitude is a form of one's perception of an object that is described with expressions of like or not. The purpose of the study was to describe the attitudes of students towards the three indicators of the attitude of the junior high school in Batanghari.

Higher-order thinking skills (HOTs) are very crucial thinking skills needed by teachers to train students to develop 21st-century learning. This study aimed to develop Multiple Choice and Essay Questions to measure the HOTs of the prospective teachers of the elementary school education department. This study used a 4-D model by Thiagarajan which…

In this paper, we discuss the results of a case study about the teaching strategies used by three primary school educators to decode Grade 4 science terminology. In South Africa, the study of science is formally introduced to learners in Grade 4. Additionally, Grade 4 is the year when learners transition from being taught in their native languages…

This research aimed to contribute to the overall understanding of pre-service teachers' acceptance of the Digital Storytelling (DS) tool. The primary associations of the Technology Acceptance Model (TAM) were tested in the academic years 2017/2018 and 2018/2019 for statistical significance when the effects of the pre-service training teachers'…

Physical sciences teachers in low-quintile South African schools avoid the use of inquiry on the grounds of inefficiency and ineffectiveness for test preparation. This avoidance is consistent with the view that the high cognitive load inquiry offers to extreme novices such as these learners may be prohibitive. Given the purported benefits of…

Owing to the popularity of tablet computers and smart phones, e-books have become an important medium for both formal and informal learning. However, conventional e-books are mainly designed to provide information in the form of multimedia, implying that students spend most of their time memorizing and comprehending what they read from e-books,…

Augmented reality (AR) offers potential advantages for intensifying environmental context awareness and augmenting students' experiences in real-world environments by dynamically overlapping digital materials with a real-world environment. However, some challenges to AR learning environments have been described, such as participants' cognitive…

This study describes how criterion-referenced feedback was produced from English language, mathematics and natural sciences monitoring assessments. The assessments were designed for grades 8 to 11 to give an overall indication of curriculum-standards attained in a given subject over the course of a year (N = 1113). The Rasch Item Map method was…

This paper, deriving from a larger study, evaluates the readability of two Grade 4 natural sciences textbooks used by learners who speak English as an additional language in two South African schools. The study is set within the context of the reading-related transitional challenges faced by English second language learners when they move from the…

Early childhood is a period of life in which lifelong attitudes, values and patterns of behaviour regarding nature are shaped. Environmental education is becoming a growing area of interest in early childhood education. The aim of the research study was to identify children's understanding of why and how their pro-environmental behaviours…

This study evaluates the effectiveness of simple and expert searches in Google Scholar (GS), EconLit, GEOBASE, PAIS, POPLINE, PubMed, Social Sciences Citation Index, Social Sciences Full Text, and Sociological Abstracts. It assesses the recall and precision of 32 searches in the field of later-life migration: nine simple keyword searches and 23…

The article discusses problems that arise from comparing different kinds of presentation modes such as texts, pictures or animations with regard to learning outcome. These comparisons are confounded with or depend on other variables like quality of the instructional design, learning content, familiarity with the presentation mode as well as…
