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…

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…

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.…

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…

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…

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…

Vision and Change [AAAS, 2011] outlines a blueprint for modernizing biology education by addressing conceptual understanding of key concepts, such as the relationship between structure and function. The document also highlights skills necessary for student success in 21st century Biology, such as the use of modeling and simulation. Here we…

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…

This study investigated the effects of two instructional approaches -- Discovery Learning Scientific Community Laboratories (DL-SCL; Treatment) and non-DLSCL laboratories (Control) -- on students' conceptual understanding, epistemological views, and academic achievement in a Physics-1 lab. Conceptual understanding was measured pre/post using the…

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…

This project utilizes visual and critical thinking approaches to develop a higher-education synergistic prelab training program for a large second-year undergraduate analytical chemistry class, directing more of the cognitive learning to the prelab phase. This enabled students to engage in more analytical thinking prior to engaging in the…

The purpose of this research was to examine and compare the effect of teaching the brightness of lamps, which is a topic for grade 11 physics lesson, on student achievement and attitude according to the 5E model belonging to the constructivist learning theory and the traditional teaching method. The research was conducted on 62 11th grade students…

The aim of this study is to examine the effectiveness of an intervention based on a series of laboratory activities enhanced with concept cartoons. The purpose of the intervention was to enhance students' understanding of acid-base chemistry for eight grade students' from two classes in a Turkish primary school. A pretest-posttest non-equivalent…

Curriculum developers and researchers have promoted context-based programmes to arrest waning student interest and participation in the enabling sciences at high school and university. Context-based programmes aim for student connections between scientific discourse and real-world contexts to elevate curricular relevance without diminishing…
