An experimental design by combining hydrogel and ethylenediaminetetraacetic acid disodium salt (EDTA) for visually displaying chemical complexation reactions is developed. The Na[superscript +] ions on the [alpha]-l-guluronic acid (G) unit of the sodium alginate molecule undergo an ion exchange with a divalent cation, so that the G units are…

The need for shifting the expository laboratory instruction style to inquiry-based approaches is widely acknowledged. Problem-based learning (PBL), one of the inquiry-based approaches, advocates students' self-directed learning. The literature indicates that scaffolding students' independent learning is necessary for a PBL environment. In our…

This article reports a quasi-experimental study which compared the effectiveness for multiword item learning of three listening-based activities: dictation, dictogloss, and answering text comprehension questions. In a dictation, students write down segments of text immediately after listening to them, whereas in dictogloss students try to…

Language can alter our mental conceptions of space, time, and categories. While there is compelling evidence that thought can be shaped by syntactic, morphological, and lexical features of a language, less is known about the impact of phonology on thought. This dissertation uses novel objects (alien cartoon figures) and pseudoword names in three…

This study investigated the causes of modifications on "Tradescantia zebrina" leaves due to environmental effects by inquiry-based and long-term observations. These observations started with restricted face-to-face education at school during the COVID-19 and continued under the teacher's guidance in distance education. All the study…

A design experiment where students in Grade 5 (11-12 years old) play the Color Run game constitutes the context for investigating how students can be introduced to informal hypothesis testing. The result outlines a three-step hypothetical learning trajectory on informal hypothesis testing. In the first step, students came to favor sample space…

In this article, we argue that physical rooms cannot be replaced by virtual space without literally losing the student's body and that experimenting with rooms and active learning is imperative for improving and advancing students' learning. Our case study offers insight into a 'soft room experiment' without hard furniture or audio-visual…

Children on the autism spectrum often have deficits in language development. Given the resources required to provide intensive intervention services, either in person or via telehealth, it may be important to maximize instructional time by using procedures that lead to generative language use, such as matrix training. Matrix training involves…

Emotions can both facilitate and hinder learning. Emotional design features such as colors and shapes can be embedded in multimedia learning environments to manipulate learners' affects and learning outcomes. However, some studies suggest that emotional designs promote learning, while others show that they hinder it. Although Brom et al.…

This paper describes the development of a mobile application to engage students in active learning in analytical chemistry. Colorimetry is a topic in analytical chemistry that can effectively be learned through the use of mobile devices to perform colorimetric measurement in the real-life environment. Previous attempts in the development of…

This study examined how language proficiency and age of acquisition affect a bilingual language user's reliance on the dominant language during lexical access. Two bilingual groups performed a translation recognition task: Mandarin-English classroom bilinguals who acquired their dominant language (Mandarin) from birth and their non-dominant…

This paper presents results of a study investigating four teaching methods used to introduce Chinese characters to beginner learners of Chinese as a foreign language (CFL) in an Irish secondary school between September 2016 and October 2016. Approximately 98 learners aged 14-16 were divided into four groups and taught for two one-hour classes per…

This study investigates the effects of Processing Instruction (PI) on the acquisition of grammatical gender and gender-marked pronouns in German. PI was compared to Traditional Instruction, i.e. a traditional, vocabulary-oriented approach using color cues (TI) and a Categorization and Memorization task (CM). The results of an immediate posttest…

The learning difficulty known as dyslexia affects up to ten per cent of the adult population. In current teaching practice in Higher Education Institutions (HEIs), however, there is still little awareness of how dyslexia-friendly language course materials can be created. Language learning materials, although often delivered in novel digital…

This paper introduces a blended learning context that creates a community of practice. This community of practice presents a combination of face-to-face facilitated learning, e-learning, and self-study. A set of in-class and online linguistic activities was used in the implementation of this experiment to investigate the efficacy of performing…
