The purpose of this study is to investigate the effectiveness of guided-inquiry approach in science classes over existing science and technology curriculum in developing content-based science achievement, science process skills, and attitude toward science of grade level 6 students in Turkey. Non-equivalent control group quasi-experimental design…

Science education reform efforts have highlighted the need for a scientifically literate citizen, capable of using their scientific knowledge and skills for reasoning, argumentation, and decision-making. Yet little is known about secondary science teachers' understandings of these reform efforts, specifically their knowledge, skills, and abilities…

Graduate students in chemistry, and in biological and biomedical fields must learn the fundamentals and practices of peptide and protein chemistry as early as possible. A project-oriented approach was conducted by first-year M.Sc and Ph.D students in biological sciences. A blind glass slide containing a cellular smear and an aqueous cellular…

How can science instruction engage students in 21st-century skills and inquiry-based learning, even when doing simple labs in the classroom? We collaborated with teachers in professional development workshops to transform "cookbook" activities into engaging laboratory experiences. We show how to change the common classroom activity of DNA…

The purpose of this experiment is to provide students with the essential skills and knowledge required to perform the extraction, isolation, and structural elucidation of parthenolide from "Tanacetum parthenium" or feverfew. Students are introduced to a background of the traditional medicinal uses of parthenolide, while more modern applications of…

The growth of pollen tubes is one of the most characteristic events in angiosperm reproduction. This article describes an activity for visualizing the journey and guidance of pollen tubes in the reproductive structures of a flowering plant. The activity uses a semi-in vivo system with rapid-cycling "Brassica rapa," also known as Fast Plants.…

With the increased focus on both inquiry and 21st-century skills such as collaboration and problem-solving, teachers at all levels are looking for engaging ways to create more student-centered classrooms in which students can learn more than "just" science content. Discovering and developing creative science activities designed to accomplish…

The theory of constructivism states that learning is non-linear, recursive, continuous, complex and relational--Despite the difficulty of deducing constructivist pedagogy from constructivist theories, there are models and common elements to consider in planning new program. Reflective activities are a common feature of all the programs of…

On the Saturday before Halloween, hundreds of students and their parents went from booth to booth participating in science activities at an annual Fall Festival and Learning Fair. The Fall Festival and Learning Fair is a valuable annual partnership where culturally relevant teaching engages each child in hands-on, standards-based science lessons.…

Introducing research in undergraduate biology studies may contribute to creating research vocations and generate the idea that science may influence all aspects of common life. However, laboratory practices are too often disconnected from current investigations and rarely address real-life questions that are really interesting for students.…

Statistical literacy is essential to scientific literacy, and the quest for such is best initiated in the elementary grades. The "Next Generation Science Standards and the Common Core State Standards for Mathematics" set forth practices (e.g., asking questions, using tools strategically to analyze and interpret data) and content (e.g.,…

New technological developments have minimized training, hardware expense, and distribution problems for the production and use of instructional videos, and any science instructor can now make instructional videos for their classes. We created short "Khan style" videos for the topic of buffers in biochemistry and assigned them as…

In fall 2012, an interdisciplinary team of science, English, and library faculty embedded reading, writing, and information literacy strategies in Science, Technology, Engineering, and Mathematics (STEM) curricula as a first step in improving student learning and retention in science courses and aligning them with the Next Generation Science and…

How can educators provide children with a genuine experience of carrying out an extended scientific investigation? And can teachers change the perception of what it means to be a scientist? These were key questions that lay behind "The Human Condition" project, an initiative funded by the Primary Science Teaching Trust to explore a new…

Over the past 50 years, considerable research has been dedicated to chemistry education. In evaluating principal chemistry courses in higher education, educators have noted the learning process for first-year general chemistry courses may be challenging. The current study investigated perceptions of faculty, students and administrators on…
