Understanding how learners interpret visual representations of invisible scientific phenomena is crucial for teaching and designing effective instructional materials. This study investigated which visualizations of infrared radiation, radiation absorption, and molecules are perceived as most intuitively comprehensible by students and adults.…

Despite the recognized link between scientific reasoning, mental sets, and conceptual change, the cognitive mechanisms underlying successful conceptual change remain unclear. To explore this, we developed computer-based reasoning programs with and without mental set support to examine their effects on conceptual change in tasks of varying…

In an increasingly online world, multimedia content for instructional use in chemistry is abundant. It can be difficult to discern a good resource from a poor one, even if the chemistry content in the video is accurate (which it may not be). Sound chemistry content alone does not guarantee that the videos were made with best principles in mind…

In science education, the abstraction and complexity of scientific concepts are usually stumbling blocks that prevent students from learning science. Recently, augmented reality (AR) has offered transformative potential to support scientific concept learning by visualizing scientific phenomena and enhancing students' experiences. However, the lack…

This research employs the fuzzy-set qualitative comparative analysis (fsQCA) method to investigate the configurations of multiple factors influencing scientific concept learning, including augmented reality (AR) technology, the concept map (CM) strategy and individual differences (eg, prior knowledge, experience and attitudes). A quasi-experiment…

By using information technology, science learning can be widely disseminated, including, for example, to rural schools. However, the implementation of inquiry-based science learning with action-to-ground science concepts for rural learners needs to be explored. To address this purpose, the present study adopted "live stream" technology…

The alternative conceptions that students hold put a brake on subsequent meaningful learning, and therefore, the identification of these wrong ideas is crucial for effective teaching and academic success. Undergraduate STEM students often perceive Chemical Thermodynamics as a difficult subject, in which entropy has been pointed out as a threshold…

Students are known to have various difficulties in dealing with organic reaction mechanisms. A systematic classification of these difficulties appears necessary to design appropriate support. This paper presents insights into whether and how Bloom's revised taxonomy can be used to classify student difficulties in dealing with organic reaction…

Two generative approaches to reaction mechanism instruction for novice students were compared to lecture instruction. In both approaches, students were coached to propose selected reaction mechanisms based on prior knowledge. New instructional methods were correlated with increased skill in representations of electron movements and other gains.…

Even after research-based instruction, students who demonstrate the ability to assemble relevant conceptual knowledge on one physics question may have difficulty assembling that same knowledge on a closely related problem. Recent research has suggested that reflexive, bottom-up reasoning processes seemingly unrelated to the physics concepts…

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…

This generic qualitative study examined how mid-to-late career experts in the U.S. space exploration sector transfer tacit knowledge to novices, with a particular focus on fostering employee engagement. Semi-structured interviews were conducted with ten industry experts from various sectors within space exploration. Thematic analysis identified…

Background: Digital game-based learning (DGBL) has shown promise in enhancing learning and motivation, with appropriate scaffolding playing a crucial role in facilitating student inquiries and knowledge acquisition through science games. While scaffolding is generally effective in promoting learning in DGBL, there is variability among different…

When characterizing students' item-solving strategies, methods such as interviews and think-aloud protocols are often used. However, these measures provide limited information about sub-or preconscious signals and cognitive processes that also affect students' item-solving strategies and abilities. A growing number of researchers in chemical…

Background: The question of the efficiency of withholding answers and the physical manipulation of material in science education has become the target of a large number of researchers (proponents of the Cognitive Load Theory) in recent years. However, no research has been found examining the contribution of these elements of teaching to the…
