This paper reports the findings of the second and the third year of a four year longitudinal empirical research into the modification of 'step-by-step' instructions to practical activities which require one or more steps to be designed by the students. This method had been successfully applied for a short period for 14-15 years old students.…

Lecture-only chemistry courses without a dedicated laboratory component present a significant challenge for instructors to reinforce course content with hands-on learning experiences. This is especially true for lecture courses in which students are unable to directly visualize and operate instrumentation. Herein, we present an in-class activity…

The present study analyses the impact of negotiation processes on activating argumentative resources for decision-making in a socioscientific issue (SSI) in biology classes. The research focuses on the potential of group-based negotiation processes to activate the use of relevant argumentative resources without any prescribed or explicit…

The researchers developed a youth weather and climate curriculum using a science comprehension model that integrates experiential and inquiry-based learning approaches with developing science knowledge, science skills, and reasoning abilities. The purpose of this study was to pilot the curriculum to determine if it would improve youth science…

The investigation of Science, Technology, Engineering, and Mathematics (STEM) and the quality of education within and between the four disciplines continues to be a topic of concern throughout the United States. Employers, policymakers and educators have recognized a need for a stronger focus on the quality of STEM education in schools (Becker…

Often overlooked in many molecular cell biology laboratory and cell culture courses, suspension cells represent an important aspect of molecular cell biology and cell culture. Most primary cell cultures and cell lines are adherent cells which grow in monolayers on surfaces. However, other cells such as hematopoietic cells, certain tumor cells, and…

To evaluate the recent advances in learning progression (LP) research and identify future research directions, we reviewed LP literature from 2006 to 2018. Through a systematic search of Web of Science databases and key journals, we located 130 LP articles published between 2006 and 2018. Among these articles, we reviewed 86 studies. The review…

Single-outcome experiments are used in the undergraduate instructional laboratory, particularly for large lectures associated with multiple sections of instructional laboratories, due in large part to efficiencies associated with chemical purchases, experiment preparations, and assessments. Despite the practical advantages, single-outcome…

We constructed a low-cost experimental kit consisting of a compact 532-nm diode laser, optics, and optomechanical components that arrange on a small honeycomb breadboard. The kit is flexible enough to construct five typical wave optic experiments, e.g., double-slit interference, Michelson and Mach-Zehnder interferometers, diffraction, and Malus's…

Before students learn Kirchhoff's rules, they are typically taught how to solve "combined series-parallel" circuits. The method presented in many textbooks begins by drawing a series of simplified circuits, replacing series and/or parallel elements with their equivalent resistances, eventually reducing the circuit to a voltage source and…

This study explores how life science researchers conceptualize, operationalize, and value Interdisciplinary Research (IDR). We interviewed a sample of 10 established life science faculty to understand the researchers' lived experiences and perspectives on participating in IDR. Six themes emerged from our data: (1) IDR requires the integration of…

Studies indicate that the failure of science education to meet the needs of the 21st century is to some extent due to the inability to incorporate scientific reasoning and higher order assessments in the school instruction. Though the outcomes of education seek higher-order thinking abilities there is a lack of high ability assessments in…

Rapid developments in educational technology show its impacts on classes. One of the recent trends in science education is virtual laboratory environments. The goal of this study is to reveal the effects of inquiry-based hands-on and virtual laboratory environments on pre-service science teachers' inquiry skills. A quasi-experimental research…

Conceptually understanding chemistry requires the ability to transition among representational levels to use an understanding of submicroscopic entities and properties to explain macroscopic phenomena. Past literature describes student struggles with these transitions but provides limited information about upper-level post-secondary chemistry…

The epistemic understanding of science has always been an important part of science education, and critical engagement with socioscientific issues (SSI) is a desirable outcome of scientific literacy. However, investigations into the link between these two concepts have been inconclusive. Many students have very limited interest in epistemic…
