The concept of paradigm became, in the middle of the last century, a central concept in the philosophical discussion about the nature of scientific knowledge. However, little attention has been paid to the strength of this concept in the constitution of the senses in general and, in particular, about its role in the transmission and acquisition of new scientific concepts, not only in the community of scientists, but also among basic-science teachers and students. I argue that a Wittgensteinian-inspired reflection on the transcendental use of this concept, as part of the grammar of scientific concepts, can clarify not only fundamental questions about the nature of scientific activity (avoiding both dogmatic and relativistic conceptions), but can also provide us with clues to identify sufficient, though not necessary, conditions so that something becomes an object for scientific thinking in the context of school education.

Abstract The study assessed the availability of laboratory resources, teachers’ and students’ involvement in practical activities in Basic Science in junior secondary schools in Osun State Nigeria. These were with a view to ascertain the availability of laboratory resources in the teaching of Basic Science in junior secondary schools and the involvement of teachers and students to practical activities in the state. The study employed a descriptive survey research design. The population for the study consisted of all Basic Science teachers, facilities for teaching Basic Science and all junior secondary school II students in Osun State. Ten schools were selected from each senatorial district through simple random sampling technique, from each school, ten students from JSSII were also randomly selected through simple random sampling technique to take part in the study. Basic Science teachers found in the schools were purposively used for the study because of their discipline and numbers. The facilities for the research were also purposively selected based on a must for teacher to use in the course of their teaching. Three instruments were used for data collection. They are: Observation Checklist for Basic Science Laboratory Facilities (OCBSLF), Questionnaire for Teachers on Teachers Involvement in Practical Activities (QTTIPA) and Students’ Questionnaire on Basic Science Laboratory Facilities (SQBSLF). Data collected were analyzed through simple percentages. The results of the study showed that 14(40.0%) schools indicated that beakers, boiling tubes, conical flask and cylinder are available while 21(60.0%) schools indicated that beakers, boiling tubes, conical flask and cylinder are not available, 10(28.6%) schools indicated that flat bottom flasks are available while 25(71.4%) schools indicated they are not available, 11(31.4%) schools indicated that round bottom flasks are available while 24(68.6%) schools indicated they are not available, 8(22.9%) schools indicated that hand lenses are available while 27(77.1%) schools indicated they are not available, 7(20.0%) schools indicated that Ammeters are available while 28(80.0%) schools indicated they are not available, 9(25.7%) schools indicated that Resistance box are available while 26(74.3%) schools indicated they are not available, 3((8.57%) schools indicated that plastic mammalian models (heart, eye, ear, and skeleton) and First Aid box (fully equipped) 3((8.57%) are available while 32(91.3%) schools indicated that they not available, 1(2.86%) schools indicated that Meter Rule, Rheostats, Connecting wires, Spatula are available while 34(97.4%) schools indicated they are not available. The results of the study showed that on the average teachers did not use laboratory facilities to teach the students and students are rarely involved in practical activities in schools. The study concluded that laboratory resources are not available to teach students Basic Science in junior secondary school level.

Science Concepts

Abstract Studies have shown that inadequate definitions of scientific concepts could complicate the learning of science and could prevent students from understanding the definitions of scientific concepts. The article provides a framework for defining scientific concepts in primary, secondary, and university education by proposing teachers draw attention to five common features of a definition: object/system, nature/characteristics, cause/effect, mathematical expression/equation, and condition/ reference frame that can help students to consider four dimensions, including, ‘comprehensiveness,’ ‘precision,’ ‘consistency,’ and ‘circularity’ when learning science concepts. This framework can be used by science teachers to guide students to analyze and redefine scientific concepts in the classroom and may be especially beneficial for students in Asian countries where teachers and students often rely on rote memorization as a strategy for learning scientific concepts. We conclude by describing the need for future studies in educational contexts in Asian countries where pedagogical strategies have traditionally emphasized memorization of science concepts.

The University

Research is considered a function aimed at obtaining new knowledge and its application for the solution to problems or questions of a scientific nature, The universities framed in the fulfillment of their social function have a complex task given by training a competent professional who assumes research as part of their training and who learns to ask questions that they are able to solve through scientific research.  Scientific research is an indicator of the quality of processes in the university environment, so it must be increased by virtue of the results of the work carried out by research teachers and students the objective of this work is to know the perception of the teachers of the Faculty of Medical Sciences of the University of Guayaquil about the scientific activity. Objective: to know the perception of the teachers of the Faculty of Medical Sciences of the University of Guayaquil about the scientific activity. Methods: theoretical and empirical level were used, a questionnaire with closed questions aimed at knowing the opinions on the research activity in this institution was applied. Result: that of the sample analyzed 309 (39.3%) said they agreed with the training for the writing of scientific articles. 38.6% said they agree with the training on research projects. Conclusion: that teacher’s research should be enhanced to ensure the formation and development of research skills in students.

Central Concept

The article deals with correspondence in natural history in the eighteenth century between England and North America. The corpus discussed consists of correspondence between John Bartram and Peter Collinson, and between Alexander Garden and John Ellis. The approach used in the study is qualitative and rhetorical; the main point considered is how the letters construct scientific centre and periphery in the eighteenth-century Atlantic world. A central concept is the “colonial exchange”, whereby “raw materials” from the colonies — in this case plant and animal specimens, along with proposed identifications and names — are exchanged for “finished products”, in this case codified scientific knowledge contained in publications.

Educational Potential

Mobile technology is now part of the everyday life of teachers and students and thus tends to become an inseparable part of the educational activities. Teachers and students are increasingly using mobile technologies in teaching and learning. Therefore, it is purposeful to responsibly integrate technologies into the educational process. However, technical and pedagogical support is necessary in order to facilitate both teacher and students’ understanding of this educational potential. Besides, it is still very little known and there is very little evidence about the effectiveness of the application of these technologies in the teaching/learning process. This research aims to explore the perceptions of Romanian and Lithuanian teachers regarding the use of mobile technologies in education. Keywords: motivation to learn, mobile technology, preliminary study, science education, science teachers.
