This study explored the effects of explicit and implicit epistemologically enhanced instructions probing 9th-grade students' personal epistemologies on their physics-related personal epistemology (PPE) and physics achievement in the heat and temperature unit. In the implicit epistemologically enhanced instruction (IEEI), different dimensions of…

This study examined fostering low-achieving students' epistemic understanding of discourse in knowledge building classrooms using video-based visual learning analytics. The participants were two Grade 9 visual arts classes of low-achieving students. The experimental class (n = 33) engaged in a knowledge building classroom supported by video-based…

This paper illustrates the role of metalanguage in an explicit literacy instruction to talk about the forms and functions of scientific genres, particularly the genre of explanation. In the context of science, metalanguage refers to the technical terms for talking "about" scientific language using words like law, hypothesis, and…

Background: South Africa's "Language-in-Education Policy" (LiEP) provides for bi/multilingual education, but schools are only supported to choose monolingual English language policies from Grade 4 and ignore the learners' home language or languages as resources for learning. Many teachers translanguage orally, using the learners' home…

According to our approach to mathematics education, the optimal aim of the teaching of mathematics is to assist students in achieving efficient mathematical work. But, what does efficient exactly mean in that case? And how can teachers reach this objective? The model of Mathematical Working Spaces with its three dimensions--semiotic, instrumental,…

In 1820 the Danish scientist Hans Christian Ørsted discovered the relationship between electricity and magnetism by his famous wire-compass experiment. Ørsted was one of the foremost scientists of the nineteenth century, and he was also one of the leading figures in Denmark in the 19th century with a vital influence in the fields of aesthetics,…

This paper reports results from a six-state study of 62 USA social studies classrooms. We examined the extent to which intellectually challenging authentic pedagogy was present in study classrooms, the characteristics of classroom practice at different levels of authentic pedagogy, and how those characteristics may promote or inhibit high levels…

This paper explores affordances in teaching evolution, especially those in which evolution is made relevant to and argued for in a grade 9 biology classroom, thus giving potential answers to the pupils' legitimate question,"'why am I learning evolution?" The aim of the paper is methodological in the sense that it explores whether the…

This study examines how a first-year biology teacher facilitates a series of whole-class discussions about evolution during the implementation of a problem-based unit. A communicative theoretical perspective is adopted wherein evolution discussions are viewed as social events that the teacher can frame intellectually (i.e., present or organize as…

Background: Although research on epistemological beliefs has expanded over the past two decades, there are still some issues that need to be explored, such as whether epistemological beliefs are domain general or domain specific. Purpose: One of the purposes of this research was to determine if high school students' general epistemological beliefs…

This research provides an analysis of the relationship between a student's beliefs and mathematical behaviors over a seventeen-year period. Romina, the student of focus in this case study, was among the original participants in a longitudinal study which explored how students build mathematical ideas when working collaboratively on problem-solving…

In this paper, we describe two central epistemological norms related to the importance of making investigations and to scientific language and its logic. These norms have been identified in empirical material consisting of 200 video-recorded lessons in three different science classes. With regard to the learning of science and socialization, we…

The examination of the development of students' epistemological beliefs is important. There is little empirical evidence for precisely how epistemological beliefs are altered. Therefore, the purpose of this study was to investigate the effects of constructivist teaching on students' epistemological beliefs in physics. One-group pretest-posttest…
