This study examined the impact of sequencing practicums for welding on students' ability to perform a 1F (flat position-fillet lap joint) weld on low-carbon steel. Participants were randomly assigned a specific practice sequence of welding for using gas metal arc welding (GMAW) and shielded metal arc welding (SMAW). A total of 71 participants…

Laboratories are important environments in science teaching. There is no doubt that the employment of technology in these environments may change the learning of science, especially as the technology has made its way into nearly every aspect of daily life. This study aimed to investigate the impact of using virtual labs on students' achievement…

The authors examined college students' perceptions about their middle school and high school preparation for college science courses as well as what led them to study or not study science in college. Analysis of a survey using mixed methods revealed that the more laboratory techniques students felt proficient in conducting and the more science AP…

In this study the Delphi technique has been used to develop a list of educational competencies for preparing secondary agricultural education instructors to effectively manage their school greenhouse facilities. The use of specialized facilities in agricultural education requires appropriate preparation of agricultural education teachers. The…

Many studies have stressed students' lack of understanding of experiments in laboratories. Some researchers suggest that if students design all or parts of entire experiment, as part of an inquiry-based approach, it would overcome certain difficulties. It requires that a procedure be written for experimental design. The aim of this paper is to…
