High quality feedback on assessments and deliverables is vital to student success. This pilot study sought to understand the impact of combining positive and performance-gap feedback in an immediate feedback scenario where students were provided multiple attempts to complete an assignment. 176 online undergraduate students were surveyed after…

Universities are recognizing the need to prepare graduates to think conceptually and have the ability to take on complex, real-world problems. Strategies to assess conceptual knowledge are limited and often require more time and effort to complete than is accessible for most undergraduate courses. Card sorting is a very broad technique for…

This study introduces a small-scale chemistry practicum technique with the concept of acid-base identification, determination of pH with indicators, and neutralization reactions with the concept of titration. The first experiences of teachers and students in small-scale chemistry practicums are revealed. Action research was carried out to…

Purpose: This study aims to present a high-end lesson study (HELS) model to develop students' subject competency. Data were collected from a Beijing suburban key senior high school in China. How the subject competency framework (SCF) supports HELS and develops students' subject competency in practice are discussed in this study.…

Problem-solving skills are essential to help students in expressing their ideas. However, problem posing is a method that can empower problem-solving skills. This study aims to determine the effectiveness of mind mapping assisted with a problem-posing method in online Schoology-based learning. This experimental research used the posttest-only…

Students are introduced to the term wavelength in optics at school level. In this paper, we present an inexpensive and simple method to measure the wavelength of the light of a light emitting diode using a light depending resistor. This experimental set-up is developed at Science Laboratory, Nehru Planetarium (Mumbai), India. It is useful as an…

The present study aims to investigate university students' conceptions of liquids with the help of the scientific story writing technique, which is one of the alternative assessment techniques. The study group comprised students studying science (n=50) and biology teaching departments (n=20) in Turkey. Thus, the study carries within two groups. In…

The study aims to determine the effect of socioscientific issues-based activities on the attitudes of primary school teacher candidates' about life science teaching. In this research, 78 primary school teacher candidates (52 females, 26 male) determined by criterion sampling method participated. Attitude Scale of Life Science Teaching was used as…

A central goal of introductory physics for the life sciences (IPLS) is to prepare students to use physics to model and analyze biological situations, a skill of increasing importance for their future studies and careers. Here we report our findings on life science students' ability to carry out a sophisticated biological modeling task at the end…

The "Primary SPACE Project Research Report: Sound" (Watt and Russell, 1990) provides interesting reading relating to primary-aged children's concepts of sound. It reveals a range of children's views on how sound is made, how sounds are heard and how sound travels. While some children are shown to have knowledge that sounds travel and are…

Inquiry-based representation-focused approaches in science education have shown promising outcomes when students engage in knowledge building via an active process of constructing, coordinating, and evaluating representations. To date, much of the existing research around these approaches has taken place in pre-digital classrooms, but the…

Integrated Science, Technology, Engineering, and Mathematics (STEM) education has gained popularity worldwide. With the twenty-first century's different economic, political, and societal needs, nations intend to train citizens as better problem solvers. The current integrated STEM movement has influenced science curriculum documents and science…

In this article, the author describes an activity using physical models -- each a clear plastic box enclosing a miniature coastal town, complete with real water in the "ocean." This activity shows students a natural cause-and-effect relationship that is scientifically simple, yet even many adults don't grasp the worldwide implications:…

The advancement of breakthrough concepts in science and their implementation in society can only be achieved by starting early with the education of new generations of scientists. The concept of 'Replacement, Reduction and Refinement' (the 3Rs) in regards to animal use was first described by Russell and Burch in 1959. The 3Rs have nowadays a…

The topic 'photosynthesis' contains many intangible and abstract scientific concepts, regarding which students hold many preconceptions. Conceptual learning is a process of co-creation and flow that requires the teachers' higher educational level on conceptual teaching. The present research considers photosynthesis as an example. Results of Ball's…
