With the continued spread of the COVID-19 crisis, the universities were closed temporarily in Turkey just as in the rest of the world. As a result of this, many educators and students tried to adapt online education quickly. This research study examined 67 pre-service teachers' views on online chemistry laboratory learning experiences amid the…

Peer assessment has been shown to advance learning, for example, by improving one's work, but the variance of learning benefits within or between studies has not been explained. The purpose of this case study was to examine what kinds of pathways students have through peer assessment and to study which factors affect them when peer assessment is…

This study developed and implemented a learner-centered assessment named Creative Exercises (CEs) in introductory chemistry courses at a four-year university and a two-year community college. CEs were developed and implemented as an intervention for treatment groups. The control groups only used traditional assessments such as multiple-choice and…

This communication reports the curriculum changes and how they worked when an upper-level experimental physical chemistry course had to switch from face-to-face to online teaching within a matter of days. Although several of the learning goals of the laboratory-based course could still be met in the online environment, others required…

Growing evidence shows that participation in out-of-school time (OST) activities positively supports youth development in general. However, simply participating in a self-identified STEM program is not sufficient. Youth will benefit more if they participate in "quality" afterschool programs. Therefore, a common understanding of quality…

The availability of reliable evidence for teaching practices after professional development is limited across science, technology, engineering, and mathematics disciplines, making the identification of professional development "best practices" and effective models for change difficult. We aimed to determine the extent to which…

Students often complain about their perceived disconnect between the time and effort spent studying and their subsequent performance on exams. Robert Bjork's research asserts that retrieval of stored information acts as a memory modifier, and that using tests as learning events creates "desirable difficulties that enhance learning."…

Video games have become a popular medium in our society, and recent scholarship suggests that games can support substantial learning. This study stems from a project in which we created a video game enabling students to use biotechnology to solve a societal problem. As students engaged in the game, they necessarily interacted with the underlying…

This article discusses learning that occurred during primary school visits to the UK National Marine Aquarium (Aquarium). Before visiting, children were asked to independently create a drawing of marine life off the Devon coast and a drawing of tropical reef marine life, allowing an assessment of prior knowledge. Post-visit, children created…

This study examined the effects of professional development on teachers' assessment literacy between two groups of teachers: (1) teachers who were involved in ongoing and sustained professional development in designing authentic classroom assessment and rubrics; and (2) teachers who were given only short-term, one-shot professional development…

The goal of the Department of Biological Sciences faculty was to evaluate how effectively our undergraduate biology program supports the goals and intended outcomes of our department and institution. Student responses in written assessment tests have provided the foundation of this evaluation. Each semester questions were selected by a…

This study evaluated the effect of a pilot Pre-AP® Science Vertical Team Summer Institute on teacher practices and perceptions of the program. The overarching goals of the Vertical Teams Institute were focused on the tools needed to build or strengthen an AP® Vertical Team and to align science curriculum across grade levels. The evaluation also…

The study analyzed 2005 posttest data compared to 2008 posttest data to determine student end of school year academic achievement outcomes across three academic levels (above average, average, and below average chemistry potential) and two teacher homework evaluation methods (assigned but not graded and assigned and graded) on teacher prepared…

For the forty-first time, the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented at the annual AECT Convention in Kansas City, Missouri. The Proceedings of AECT's Convention are published in two volumes. Volume 1 contains twenty-seven…

With issues of teacher quality in the spotlight, it has been suggested that teachers of mathematics and science too often lack content knowledge in the subjects they teach. Accordingly, research is needed to determine whether teacher ineffectiveness in these subjects is more frequently caused by deficiencies in content knowledge or in pedagogical…
