“…Despite extensive literature evidence indicating a lack of attempt to overcome anxiety in laboratory activity [51] [52], the current study provided sufficient evidence that self-directed laboratory activity is an effective method of addressing anxiety. Not only is this true for the present study, but there are also accounts in the literature indicating the meaningful contribution of self-directed learning to promoting success, readiness, and diminishing laboratory anxiety in chemistry [53].…”

This mixed-design study was implemented through a one-group pretest-posttest preexperimental design in a secondary school at Cagraray Island, Philippines using the printed Project HANDLE manual. Project HANDLE is a stand-alone intervention composed of homebased laboratory experiments that target the development of science process skills (SPS) of 35 Grade 7 learners in Life Science delivered through distance learning modality. This study aims to assess the effectiveness of Project HANDLE in improving the SPS of Grade 7 learners as a springboard for the construction of a framework for home-based laboratory exercises. A validated researcher-made test and a survey questionnaire were used to collect data on scores of the pretest and posttest, and experiences in the implementation of Project HANDLE. To rank the tested SPS, descriptive statistics such as mean, percentage, and mean gains were employed, while inferential statistics such as t-test and Cohen's d were used to assess the significance of the differences in scores and the degree of influence of the intervention. Results revealed significant improvement in the level of each tested SPS (p<0.05) with Measuring as the most developed SPS and Observing on the opposite extremity. The code of experiences of the learners in Project HANDLE showed five factors, (1) overcoming anxiety, (2) independence, (3) enjoyment, (4) conceptual formation, and (5) ease. A framework for distance learning modality on laboratory experiments was proposed, integrating contextualization, culture-based approach, and brain-based approach to assure the development of SPS and other laboratory factors. Project HANDLE was found to be effective in developing SPS, while it is recommended to use the intervention for integrated SPS and implement the proposed framework. Furthermore, the outcome implies that SPS can be developed without the supervision of a teacher or an expert.

“…[15] stated that practical work has a significant effect on students' achievement. In contrast, findings by [3] showed that laboratory anxiety can happen during the use of chemicals and working with laboratory equipment which can lead to accidents or affect students' performances. Therefore, safety practices in the chemistry laboratories are not only to safeguard an individual from the risk of accidents and health hazards but also to ensure effective teaching and learning.…”

Teaching and learning of chemistry involves scientific tests and experiments that take place in laboratories. It involves using hazardous chemicals and equipment posing risks and health hazards to the users. Hence, the users should be thoroughly versed with laboratory safety practices. Therefore, an attempt to understand the safety practices in chemistry laboratories in schools have been examined in this study.The data were collected administering a mixed method. Both descriptive and inferential statistical tools were used to analyse quantitative data while qualitative data were analysed thematically. Congruency of the eight predetermined themes was established by triangulating the quantitative and qualitative data using Statistical Package for Social Sciences version 21.The results indicated that the schools had good safety practices with adequate laboratory facilities and safety skills. The schools were also aware of emergency planning and chemical storage and labeling. However, schools lacked properly trained safety practitioners. It was also observed that chemicals and waste materials were disposed of without treatment. Further, it was also observed that there were shortages of safety gloves and goggles fume hood and pipette fillers.The study recommends school administrators, chemistry teachers, and laboratory assistants to procure unavailable items required for the safe conduct of chemistry laboratory activities. The study further recommends the Ministry of Education (MoE) to provide training to chemistry teachers and laboratory assistants on the safe handling of hazardous materials and on first aid techniques to address accidents.

“…Among the broadly accepted prerequisites for interactive research in an organizational context is the researcher's presence as "being there" (Ellström at al., 1999;Bryman, 1989), or/and active participation in the organization as "being one variable, interacting with the organization or building a collaborative inquiry" (Bryman, 1989;Shadish et.al, 2002;Acar Sesen and Mutlu, 2014), and systematically changing the research field by developing different applications of a studied phenomenon (Kuzu, 2009).…”

Towards Lean Remanufacturing : Challenges and Improvements in Material and Information Flows

Remanufacturing is an environmentally sound material recovery option which is essential to compete for sustainable manufacturing. The aim with remanufacturing at a majority of companies is to prolong physical product performance by delivering the same or betterthan-original product quality. In general, remanufacturing is an industrial process that brings used products back to useful life by requiring less effort than is demanded by the initial production process. Consequently, from a product life-cycle perspective, remanufacturing generates great product value.Remanufacturers lag behind manufacturers since they often face complex and unpredictable material and information flows. Based on a review of remanufacturing research, remanufacturing challenges in material and information flows can be classified into three groups: insufficient product quality, long and unstable process lead times, and an unpredictable level of inventory. While some remanufacturing researchers state that manufacturing and remanufacturing are significantly different, they have more in common than many other processes operations. Therefore, to sustain competitive remanufacturing, companies investigate an opportunity for improvement through the employment of lean production that generates significant benefits for manufacturers.In order to investigate the potential to address remanufacturing challenges by lean production, a Minimum time for material and information flow analysis (MiniMifa) method was developed. This method originates from the value stream mapping (VSM) method, broadly practiced to bring lean to manufacturing companies. The focus of MiniMifa was to collect empirical data on the identified groups of remanufacturing challenges from the remanufacturing perspective, and to provide a basis for the development of improvements originating from lean principles.Lean production was selected for this research due to its system perspective on material and information flows. Among the defined lean principles in remanufacturing, a pull principle was investigated at the case companies. The suggested principle demonstrated a reduction in lead time, followed by improvements in inventory level and product quality. However, in order to become lean, remanufacturers have to overcome three levels of lean remanufacturing challenges: external and internal challenges as well as lean wastes.Finally, this research reduces the gap between academia and industry by contributing with a possible solution to the identified remanufacturing challenges in material and information flows.
