Knowledge space theory (KST) is a mathematical framework for modeling and assessing student knowledge. While KST has successfully served as the foundation of several learning systems, recent advancements in machine learning provide an opportunity to improve on purely KST-based approaches to assessing student knowledge. As such, in this work we…

THS is applied to Science High Schools, Social Sciences High Schools, Anatolian Technical Programs of Vocational and Technical Anatolian High Schools and Project schools for student selection. With THS, approximately 10 percent of more than one million students are placed in a secondary education institution based on their preferences. The purpose…

Ensuring equal access to digital learning skills for all students is a timely goal. This paper describes results of a quasi-experiment study to test the effectiveness of an online professional development (PD) model to prepare teachers to implement web-based Strategies for Online Academic Research (SOAR) with middle school students, including…

We investigated the effects of proximal grouping of numbers, problem-solving goals to make 100, and prior knowledge on students' solution strategies in an online mathematics game. Logistic regression on 857 problem-level data points from 227 middle-school students showed that students were more likely to use productive solution strategies on…

The capacity to recognise, represent, and reason about relationships between different quantities, that is, to think multiplicatively, has long been recognised as critical to success in school mathematics in the middle years and beyond. Building on recent research that found a strong link between multiplicative thinking and algebraic, geometrical,…

Collaborative learning is a complex process during which two or more learners exchange opinions, construct shared knowledge, and solve problems together. While engaging in this interactive process, learners' satisfaction toward their partners plays a crucial role in defining the success of the collaboration. If intelligent systems could predict…

This paper demonstrates how to apply Machine Learning (ML) techniques to analyze student interaction data collected in an online mathematics game. We examined: (1) how different ML algorithms influenced the precision of middle-school students' (N = 359) performance prediction; and (2) what types of in-game features were associated with student…

The Technology Proficiency Self Assessment (TPSA) has been used since 1997 in its original form with only a few minor modifications (changing Alta Vista as a search engine example to Google). The survey instrument has retained its reliability even in the evolving arena of educational technology. The survey has been translated to multiple languages…

Mathematics teachers are vital components in determining what mathematics students have the opportunity to learn. There are a vast number of factors and reasons that influence a teacher's instructional decisions. As such, teachers rely heavily on their curricular reasoning (CR) to make decisions about what content to teach, how that content is…

In this report we further develop the notion of knowledge agent and analyse knowledge agency in an 8th grade mathematics classroom learning probability. By knowledge agency we mean the many ways and variations in which knowledge agents act. We also observe the teacher as an orchestrator of the learning process who as such invests efforts to create…

The purpose of this study is to reveal middle school mathematics teachers' experiences of using a smart phone. In the study, survey method was used. The study was carried out with 105 middle school mathematics teachers. As a data collection tool, a survey that consists of two sections was used. Percentages and frequencies were used in terms of…

There is a serious need to reconsider the adult-led, grade-centered parent teacher meetings which are standard school practice. Schools and students would benefit from elevating PTMs with student voice and formative assessment that celebrates students' efforts and motivates them to continue learning. Under a reinvented framework for meetings,…

To support our understanding of how we might support the use of modeling in PBL activities for classroom use, this study explores how to scaffold collaborative scientific modeling activities. It draws on prior work with scientific modeling centered on the use of the Component-Mechanism-Phenomenon (CMP) conceptual framework (Hmelo-Silver et al.,…

Science assessments should evaluate the full complement of inquiry practices (NGSS, 2013). Our previous work has shown that a large proportion of students' open responses did not match their scientific investigations (Li et al., 2017a). The present study both unpacks and compares the sub-components underlying students' performance for…

Although spatial thinking and reasoning is recognised as a key component for promoting STEM discipline, very little research has been done on its promotion in middle years in Australia. How do students perceive three dimensional geometrical objects? Are they able to recognise the objects from different perspectives and explain their reasoning for…
