“…In such instances remote laboratories (Cooper & Ferreira, 2009 ) not only allow greater accessibility, but have the potential to bridge the gaps in development of laboratory skills by allowing individual students to work with the physical laboratory (PL) equipment remotely (Achuthan et al., 2020 ; Lowe et al., 2013 ). The widespread reach of information technology has widened the scope of laboratory education (Achuthan et al., 2018 ; Kolil et al., 2020 ; Achuthan et al., 2017 ; Raman et al., 2011 ).…”

Access and personalized instruction required for laboratory education can be highly compromised due to regulatory constraints in times such as COVID-19 pandemic or resource shortages at other times. This directly impacts the student engagement and immersion that are necessary for conceptual and procedural understanding for scientific experimentation. While online and remote laboratories have potential to address the aforementioned challenges, theoretical perspectives of laboratory learning outcomes are critical to enhance their impact and are sparsely examined in the literature. Using Transactional Distance Theory (TDT), this paper addresses the gap through a case study on Universal Testing Machine (UTM). By comparing physical (PL-UTM) and remotely triggerable (RT-UTM) laboratory platforms, the structure and interactions as per TDT are analysed. Characterization of interactivity between remote learners and instructors disclose indicative parameters that affect transactional distances and aid in conceptual understanding in remote laboratory learning environment. An extensive pedagogical study through development of two instruments towards assessing conceptual understanding and perception of platform effectiveness that was conducted both on physical laboratory and RT-UTM showed: (1) remote users conducted experiments 3 times more frequently (2) completed assignments in 30% less time and (3) had over 200% improvement in scores when RT-UTM platform was integrated into mainstream learning.

“…The experimental self-efficacy scale provides greater flexibility in that it can be used to assess self-efficacy for a wide range of laboratory tasks and concepts rather than being specific to chemistry education. It is more applicable to students in a virtual or online laboratory (Achuthan et al, 2020 ) setting or to students in a different type of laboratory, such as an engineering or computer science laboratory.…”

Laboratory education is essential for enhancing both the understanding of concepts and skills of students. A significant barrier to excelling in laboratory practices relates to a lack of self-efficacy. Being complementary to mainstream theoretical learning, the contribution of laboratory education to impart knowledge and hands-on proficiency is often under-represented. The aim of this research was to validate a novel experimental self-efficacy (ESE) scale and explore its relationship with laboratory outcomes, using gender and year of study as mediating variables. ESE refers to students' faith in their potential to carry out experiments and achieve desired outcomes in laboratory settings. When students possess strong ESE, they display more confidence in their abilities, accept tasks of greater difficulty levels, and have more tenacity to overcome obstacles. Data from 1,123 students were analyzed, focusing on the link between ESE constructs and laboratory experiments. Results indicated that ESE had a significant impact on laboratory performance in students of both genders and was related to factors such as laboratory hazards, conceptual understanding, the sufficiency of laboratory resources, and procedural complexities. The study affirms the validity and applicability of the ESE-scale to not only multiple disciplines such as chemistry, physics, and biology but also its relationship with students' academic outcomes in laboratories.

Review transcript presents copious solar tracking methods to investigate their output potential and also outline tracker type, construction, cost, and design parameter. The solar follower systems encompassed five classifications based on the tracking methods are active, passive, semi-passive, manual, and chronological tracking are also reviewed with their application and feasibility. These all method-based research paper are compared on the basis of complexity of circuit, cost, tracking based on (radiation or astronomical equation), degree of freedom, control strategy, accuracy, energy intact, power or energy gain, tracing error, and panel efficiency. Basically, one axis and two axis sun following system review revels compare study against stable system which addressed their suitability and capability of maximum energy generation and MPPT technologies.
