This study aims to analyse students' extraneous cognitive load (ECL) in cell biology lectures. Participants in the study were 31 students of the Biology Education Department who attended the Cell Biology course from a university in Jakarta, Indonesia. The Cell Biology lectures include fours topics. The data of ECL were measured using…

An elementary-level physics approach is used to calculate a number of interesting and useful quantities related to nuclear explosions. The set of eight exercises deals with nuclear fission fragments, the variation of fissile nucleus density in a fissioning nuclear device core with time, and the fireball.

A significant approach that should be followed by physics teachers at the secondary education level in order to enhance students' understanding is to highlight the generality of the mathematical procedures that describe different physical phenomena. In this paper, the common procedure that is used to calculate the duration of various physical…

Teaching human evolution should be initialized by understanding the learners' perspective to yield fruitful results. This study was conducted to aid in achieving that objective and provide ways for educators to develop strategies that learners can perceive and appreciate, particularly those who are not inclined toward science. This study also…

Ohm's law and Kirchhoff's rules refer to stationary states and do not provide any indications of the always-present transition processes that connect these states and cause their respective setting. Through the use of suitable simulation programs these transition processes are accessible to classroom activities and allow a deeper and more coherent…

This dissertation is comprised of three studies that define and subsequently evaluate different antecedents to STEM (science, technology, engineering, mathematics) anxiety in elementary, secondary, and tertiary faculty. The literature review developed a framework of antecedents to anxiety in STEM classrooms or contexts. This was accomplished…

Context is the background or the settings of an event or idea. It is only when events or ideas are considered within the context in which they occur that they can be fully understood. In education, the application of knowledge communicated in one context to a different one is a central feature of learning. However, knowledge transfer can be…

Due to the advent of coronavirus disease in most nations throughout the world, the manner of education altered from traditional face-to-face to remote or online teaching. As a result, the new normal necessitates the adoption of an online teaching and learning platform for all levels of education. The study tested the effectiveness of a flipped…

Students' understanding of the concepts that underlie evolution are often less than optimal and make it difficult for them to accept the theory of evolution. The aimed of this study were to: 1) map students' knowledge of Mutation and Recombination (M and R); and 2) analyze the effect of gender on their chairperson. This survey research involving…

Guided inquiry learning is an effective method for learning about scientific concepts. The present study investigated the effects of combining video modeling (VM) examples and metacognitive prompts on university students' (N = 127) scientific reasoning and self-regulation during inquiry learning. We compared the effects of watching VM examples…

This study assesses the level of application of the 5E's educational model by Rwandan physics teachers and how the model affects the learning of basic classical mechanics in secondary school physics classrooms. For this analysis, quantitative data were collected using the classroom observation tool framed at the 5E's educational model. A sample of…

This study compared the effectiveness of online skeuomorphic physics inquiry-based learning with and without simulation on 8th-grade students' performance of scientific inquiry involving the spring unit. Two classes (58 students) were assigned to the online skeuomorphic physics inquiry-based learning with simulation, and two classes (59 students)…

We report a research-based proposal on electromagnetic induction within the theoretical framework of the Model of Educational Reconstruction. The proposal is based on a sequence of inquiry-based experimental activities centered on hands-on materials and "Real-Time" quantitative experiments, through which students explore the…

The video of a free-falling object was analysed in Tracker in order to extract the position and time data. On the basis of these data, the velocity, gravitational potential energy, kinetic energy, and the work done by gravity were obtained. These led to a rather simultaneous validation of the conservation law of energy and the work-energy theorem.…

Growing interest in interdisciplinary (ID) understanding has led to the recent development of four ID assessments, none of which have previously been comprehensively validated. Sources of evidence for the validity of tests include construct validity, such as the internal structure of the test. ID tests may (and should) test both disciplinary (D)…
