The aim of this research is to examine the effects of laboratory activities based on the predict-observe-explain (POE) strategy on the understanding of photosynthesis and respiration concepts of pre-service science teachers, and their attitudes towards biology science and course and biology laboratory. Pre- and post-test designs with an…

This study aimed to examine the effect of three teaching approaches: The traditional teaching method, Teacher based demonstration experiment (TBDE), and the Student hands-on experiment (SHE), on students' conceptual understanding of solutions and titration. The data were collected using a chemistry achievement test (CAT) comprising of 30…

When conducting biological investigations, experts constantly integrate their conceptual and quantitative understanding of variation with the design and analysis of the investigation. This process is difficult for students, because curricula often treat these concepts as separate components. This study describes the effect of a curricular…

Undergraduate biology laboratories emphasize hands-on skills. Typically, descriptions of manual techniques are delivered via written instruction. Custom-produced prelab instructional videos, which augment prelab instruction, have come into wider use in recent years. However, institutional and economic barriers can interfere with video production…

The COVID-19 outbreak has had a significant impact on higher education worldwide. In-person courses had to be quickly transited to online, including lab courses embedded with Course-based Undergraduate Research Experiences (CUREs). In response to this challenge, we successfully converted a fully in-person biochemistry lab that integrated with a…

This study investigated the effects of practical activities and manual on science students' academic performance on solubility in Uruan Local Education Authority of Akwa Ibom State. The study adopted pretest, posttest non randomized quasi experimental design. Three research questions and three hypotheses were formulated to guide the study. One…

A concept for undergraduate mechanics courses at universities is introduced where traditional pencil-paper based exercises are partially replaced by experimental exercises, in which smartphones are used as measurement devices. A detailed guidance for practical realization and implementation of these tasks formats into the course is presented.…

Women are underrepresented at multiple levels of physics education. One avenue for understanding the classroom experiences that perpetuate underrepresentation is physics identity, defined using the three dimensions of recognition, performance, and competence. Existing literature suggests that women tend to have a much weaker physics identity than…

The 21st century student learns and communicates in the virtual world. In order to meet the individual instructional needs of the students, virtual science laboratories should be researched to accomplish the goal. This study evaluated the effectiveness of a virtual chemistry laboratory in enhancing students' conceptual understanding as a…

Laboratory experimentation in the context of school science is a widely advocated teaching strategy for the simplification of several abstract scientific concepts. Laboratory-based learning activities have proven to enhance learners' conceptual and procedural understandings of micro chemical phenomena, thus boosting achievement in chemistry…

Bioprocess engineering is a highly interdisciplinary field of study which is strongly benefited by practical courses where students can actively experience the interconnection between biology, engineering, and physical sciences. This work describes a lab course developed for 2nd year undergraduate students of bioprocess engineering and related…

The present paper reports upon the design and implementation of a novel practical work pedagogy that is shown to increase students' retention of practical procedures. The chemistry exams, for 15 to 16-year olds in England, will be assessed entirely through terminal examination questions from 2018. Longer term retention of learning is critical if…

This work describes an effective, low cost method to anodize small aluminum objects. The use of a PVC spacer between the anode and cathode significantly reduces the size of the electrochemical cell and electrolyte required for its operation. Students will explore the physical and chemical properties of aluminum and anodized aluminum. They will…

Lab activities have been innovated and progressed to fulfill the purpose that students need to experience physics concepts through hands-on and minds-on interactions. However, student-centered and conceptual activities in physics labs are challenged with time and material constraints that degrades the merits of the learning environment. This study…

The use of external representations (ERs) to introduce concepts in undergraduate biology has become increasingly common. Two of the most prevalent are static images and dynamic animations. While previous studies comparing static images and dynamic animations have resulted in somewhat conflicting findings in regards to learning outcomes, the…
