Prior studies on scaffolding for investigative inquiry practices (i.e. forming a question/hypothesis, collecting data, and analyzing and interpreting data [21]) revealed that students who received scaffolding were better able to both learn practices and transfer these competencies to new topics than were students who did not receive scaffolding.…

We study the usage of a self-guided online tutoring platform called Algebra Nation, which is widely by middle school and high school students who take the End-of-Course Algebra I exam at the end of the school year. This article aims to study how the platform contributes to increasing students' exam scores by examining users' logs over a three year…

Research in learning technologies has often focused on the affordances of single technologies such as pcs, smartphones or interactive whiteboards. However, in most learning environments technologies do not stand alone but are embedded in activity structures and webs of materials that make up the learning activity. This is specifically relevant…

This study examines the impact of Learning and Teaching Linear Functions (LTLF) professional development materials on teachers' mathematics understanding and teaching practices, as well as students' resulting algebra proficiency, learning, and achievement. Learning and Teaching Linear Functions are modular, video-based professional development…

Indigenous students in the middle-school years who experience difficulties in basic mathematics are a particularly vulnerable group. During these years gaps in performance between educationally disadvantaged students and their peers widen, potentially leading to ongoing economic and social disadvantage. This proposal reports on a teaching…

Proportional reasoning is key to students' acquisition and application of complex mathematics and science topics. Research is needed regarding how students' progress towards and come to demonstrate key developmental understandings within proportional reasoning. To this end we created and administered assessment items to 297 middle grades students.…

High-tech tools can be integrated to serve a number of purposes in the mathematics classroom, with different purposes being appropriate for different learning goals. We focus specifically on the various purposes for interactive simulations (sims). This study followed three experienced middle-school mathematics teachers integrating PhET sims into…

In a study involving 1414 elementary, middle school, and high school teachers from a large school district in the southwestern USA, the authors examine the similarities and differences among teachers at the three levels of K-12 education common in US school systems: elementary, middle school and high school. Major findings are that elementary…

This paper outlines a research study involving a University-School District partnership with the intent to increase the number of middle grades mathematics and science teachers by increasing content knowledge, self-efficacy, and interest in these content areas. The selected program component describes the authentic summer research experience that…

This paper discusses a novel approach for developing more refined and accurate learner models from student data collected from Open Ended Learning Environments (OELEs). OELEs provide students choice in how they go about constructing solutions to problems, and students exhibit a variety of learning behaviors in such environments. Building accurate…

This research presents two case studies on how human-centered design process can help the students find their purpose in making and designing in a constructionist learning-environment. Human-centered design guides students to deeper understanding of others' needs and encourages them to think and act collaboratively and creatively. When the…

Increasing racial and gender diversity has been an urgent goal in many professions and education is no exception. Though the call for more Black men is a worthy one, many challenging questions arise when one considers the country's socio-historical record. The purpose of this study is to explore some of these questions that arise as one probes the…

This research aimed to develop an assessment tool for students' Positive Experiences about Science (PES). A preliminary version of PSE was developed through literature review, consisting of academic emotion, self-concept, learning motivation, career aspiration, and attitude in science. A pilot test was conducted with 198 students and a main test…

Females are underrepresented in science, technology, engineering and mathematics (STEM) disciplines. They also tend to display less favorable dispositions towards STEM than males. This study investigates the influence of a five-day residential summer mathematics and technology camp on middle school girls' beliefs about mathematics as a gendered…

Methods of using ICT is hereby amended. We merge from the original model of work on one computer to the model of cloud services and mobile touch screen devices use. Way of searching for and delivering of information between a pupil and a teacher is closely related with this matter as well. This work detects common and preferred procedures of…
