Investigating Pupils’ English Vocabulary Learning Engagement Supported by Virtual Location-based Task Tool in COVID-19 

Vocabulary learning for English as a second language (ESL) learners is a boring experience in school education because learners have few opportunities to review and apply the vocabulary learned in class to real-life settings. In the COVID-19, learners have to stay at home most of the time, the opportunities for consolidating the vocabulary in authentic learning environments are even rare. In the light of it, this study aims to develop and implement a virtual location-based task tool (refer to Figure 1) to engage learners in game-based learning activities to perform location-based tasks in a virtual world, especially in COVID-19.

Investigation on Estimation Methods for Weibull Distributions with a Threshold Parameter Based on One-Shot Device Testing Data 

In reliability studies, as it is reasonable to assume that there is a nonzero origin below which no event can occur, Weibull distribution with an unknown location (threshold) parameter is suitable for data analysis. To the best of our knowledge, no published study has examined estimation methods for the three-parameter Weibull distributions based on binary data arising from one-shot devices collected from accelerated life tests. In this project, we will investigate three-parameter Weibull distribution with a threshold parameter and develop estimation methods for one-shot device testing data.

Investigating the Essential Components of Mathematical Modeling as a Bridge to Cross Disciplinary STEM Integration in Mathematics Teachers' Education 

We are inspired by the research report of Cai, et al (2014) on calling for research on learning and teaching of mathematical modeling in the three out of five perspectives, namely: mathematics, instructional, and teacher education. In this study, we measure how competent prospective, or fresh mathematics teachers are in certain areas of mathematics subject matter knowledge (SMK) and pedagogical content knowledge (PCK), which are decisive for quality teaching, while their knowledge of mathematical modeling will be our main focus. It is believed that effective teaching of mathematical modeling, requires at least the teachers’ capability of making real connection, using authentic approaches, applying appropriate metaphors, leading smooth transition of abstraction in delivery mathematical concepts and ideas, looking at elementary content from an advance standpoint, and skillful validation and verification of built models (Blum 2011). The knowledge of teaching of mathematical modeling is believed to be an essential component of effective teaching of mathematics in the STEM environment (Kertil & Gurel 2016).
