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…

This research is a systematic literature review study that aims to explore the evidence in publications that report on the types of misconceptions experienced by students in learning chemistry by providing types of students' chemical misconceptions based on levels and obtaining the correct formulation of misconceptions so that they can be used as…

In this article we offer a conceptual and practical contribution to the field of STEM education by investigating the concepts educators may include in Quantum Technologies (QT) outreach activities. We embed our approach in the discipline-culture (DC) framework, in which we consider the cultural nuances of QT as an important factor which must not…

A study on the misconceptions developed or held by teachers related to the two terms valence and valency was undertaken. A total of 48 teachers (26 males and 22 females) teaching the chemistry component of science subject to 14-16-year-old students, in 48 schools affiliated to one district, were randomly selected for the study by taking one…

This paper investigated the effect of outdoor teaching activities on secondary school students' acquisition of science process skills in science. Two research questions and two null hypotheses guided this study. This study adopted a single-group pre-test post-test quasi-experimental design. This study was conducted in the Mangalore North cluster…

The More Than Human (MTH; Bang and Marin 2015) world is often considered passive and neutral, not implicated in meaning-making in science classrooms. Through this framing, learning spaces are considered the backdrop upon which learning occurs, where the goal of science teaching is to explain why or predict how science phenomena-assumed as static…

Formative assessment in science has long been reported to support students' scientific understanding. It involves teachers gathering assessment evidence, interpreting it in the light of learning goals and providing feedback to bridge the gap between students' current state of understanding and the desired educational goals. This study examines how…

Concept maps help detect misconceptions and provide revision exercises to assess comprehension once a topic has been introduced. A concept map is a schematic drawing used to show the connection among the concepts in propositional form. A concept map is a helpful tool for illustrating the relationships between main concepts and sub-concepts. The…

This article presents an instructional strategy called Premise-Reasoning- Outcome (PRO) designed to support students in the construction of scientific explanations. Informed by the philosophy of science and linguistic studies of science, the PRO strategy involves identifying three components of a scientific explanation: (i) premise--an accepted…

Flotation is usually taught in Indian schools after students have been introduced to the concepts of mass, density, pressure, volume and buoyancy. This paper describes an attempt to teach the principle of flotation to a class of sixth graders--who had not yet been taught these concepts--so they could understand (and perhaps, arrive at) Archimedes'…

Development of cognitive skills is critical for developing the right conceptual ideas in chemistry. Atomic structure, bonding, and associated properties are taught as parts of high school chemistry courses worldwide. The cumulative build-up of misconceptions about the periodic table is to blame for students' poor performance on atoms and…

Thermal equilibrium is a basic concept in thermodynamics. In India, this concept is generally introduced at the first year of undergraduate education in physics and chemistry. In our earlier studies (Pathare and Pradhan 2011 "Proc. episteme-4 Int. Conf. to Review Research on Science Technology and Mathematics Education" pp 169-72) we…

This paper describes an inexpensive experiment to determine the carbonyl stretching frequency of an organic keto compound in its ground state and first electronic excited state. The experiment is simple to execute, clarifies some of the fundamental concepts of spectroscopy, and is appropriate for a basic spectroscopy laboratory course. The…

Biology is an important subject in curriculum. It helps to develop the scientific attitude, scientific temper, logical reasoning, scientific literacy, awareness of environmental issues, and respect about surrounding life among students. Biology textbook content is an authentic source of information for teachers & students. According to the…

Learning about components and processes of complex biological systems is challenging and requires abstraction through mediational tools such as text, visuals, models and visualisation experiences. The 'systems concepts' necessitate building coherent relations and anticipating consequences, requiring greater mediational support. This article…
