Conjectures are a key component of mathematical inquiry, a process in which the students raise conjectures, refute or dismiss some of them, and formulate additional ones. Taking a design-based research approach, we formulated a design principle for personal feedback in supporting the iterative process of conjecturing. We empirically explored the…

The purpose of this study was to analyze the prompts that preservice secondary mathematics teachers used for the acquisition of mathematics knowledge in dynamic geometry environment tasks. The participants, four preservice secondary mathematics teachers who were enrolled in a computer-supported mathematics education course, designed a dynamic…

In virtual reality, language learners can experience the foreign culture by exploring authentic and contextualized learning environments. To date, there is a lack of studies investigating the use of highly immersive virtual reality for cultural understanding as well as learners' attitudes toward its implementation in the language classroom. This…

Although the use of technology for pragmatics instruction has attracted significant attention from scholars, the number of studies regarding the impact of self-access materials to this end is limited. Nearpod is a useful cloud-based application to support self-paced learning. This paper aims to probe the effect of learning through Nearpod on EFL…

This study examined factors affecting perception training of vowel duration in L2 Japanese with transfer to production. In a pre-test, training, post-test design, 48 L1 English speakers were assigned to one of three groups: auditory-visual (AV) training using waveform displays, auditory-only (A-only), or no training. Within-group variables were…

Two experiments investigated the effectiveness of computer-assisted prosody training, its generalization to novel sentences and segmental accuracy, and the relationship between prosodic and lexical information in long-term memory. Experiment 1, using a pretest-posttest design, provided native English-speaking learners of French with 3 weeks of…
