This study from 2019 investigates whether the impact on a STEM teacher’s evidence-informed teaching approach using the evidence of flipping the classroom research improves students’ (13–14 years old) motivation in a Dutch setting and if this approach allows students to perform better. We report this approach in line with the cycle of expansive learning of Engeström. We asked: “To what extent can evidence based on the flipping the classroom approach improve the motivation and results of grade 8 preuniversity track students doing mathematics?”, followed by the subquestions: “To what extent does education by the FtCA increase student motivation?” and “To what extent does education by the FtCA ensure better test results for students?”. A questionnaire is used to investigate to what extent the motivation of students increased, and a teacher is interviewed about his experiences with the “flipping the classroom” model. To test whether the results have improved, a pre- and post-test is taken and analyzed. A significant increase in both intrinsic and extrinsic motivation has been found, and students gained a stronger sense of autonomy, competence, and belonging. The test results improved, but the difference is not statistically significant. However, despite the disappointing test results, the teacher was very positive about the new way of working.

Stress path is one of the very important factors of soil strength. It is significant to study the strength and reveal the importance of the impact of sand in different stress path conditions. Firstly, an ameliorating approach on implementing for the reduced triaxial extension by the conventional triaxial apparatus was discussed. Then, In order to study shear behaviors of the eolian sand under different stress path, two monotonic shearing tests with the conventional triaxial compression and the reduced triaxial extension stress path were performed and analyzed. The test results not only indicate that the amelioration on conventional triaxial apparatus is simple, practicable and inexpensive, but also reveal the difference of strength’s parameter between the reduced triaxial extension and conventional triaxial compression stress path. In sum, the stress path has important effect on the strength of the eolian sand.

Method Approach

This study aims to investigate an intervention in the application of the Butterfly Method Algorithm with the Bar Model Concept on the addition and subtractions of Fractions to Year 9 students in one of the Government secondary schools in Brunei Darussalam. The Butterfly Method is an alternative visual method for teaching fractions where the diagonal and horizontal multiplication of the denominators and numerators are employed by drawing the Butterfly. A mixed-method approach was used to explore the impact of the intervention with data gathered from the students’ written pre- and post-tests and interview transcripts. The tests conducted before and after the intervention were used to analyze students’ errors and misconceptions. The students’ written analyses of the post-test results revealed that not all of the students applied the Butterfly Method. A few students were selected for interviews in order to gain deeper insights into how they developed the errors and misconceptions from both tests. Findings from the students’ interview transcripts revealed they were not confident with the Butterfly Method, and they needed more time to be familiar with the concept. Another factor for not applying the Butterfly Method is due to students’ confusion on subtracting fractions that has the same denominators as well as subtracting a proper fraction from a whole number. This study concluded that students who applied the Butterfly Method helped them to remember the new method from the intervention satisfactorily in comparison to those who lack the confidence in applying it.

SUMMARYFrom 1958 to 1962 over 800 boars and 3,000 sows were progeny tested at the national pig progeny testing stations in Great Britain. Their test results for four traits (daily gain, feed efficiency, average backfat and carcass length) have been used to study the amount and effectiveness of selection and to review the use of the test facilities and their effect on pig improvement.The amount of selection on test results was studied by measuring the difference in performance of animals with sons subsequently tested and all contemporary tested animals. The selection differentials found were from 0·05 to 0·30 standard deviation units for the four traits studied which represents a rather mild degree of selection. Thus selection could have had only a small effect in improving the testing population. In fact sons of tested animals showed little advantage over their contemporaries in test performance. Parent-offspring regressions were calculated and these, in agreement with theoretical estimates, indicated that selection would be effective and would lead to genetic changes in any of the four traits studied. Genetic correlations among the four traits were also calculated and indicated genetic compatability in improving the four traits concurrently.Two proposals intended to increase the impact of testing on pig improvement are put forward. These are (1) to restrict the testing facilities to a small nucleus set of breeders who could concentrate on testing and selection and (2) to replace the progeny testing by performance testing which would allow a more intense selection and a greater rate of improvement for the same testing facilities.

This paper compares the evidence-based outcomes between cochlear implants and hearing aids during the past several decades. Despite many similarities, there are also some important differences that define the progress for the two disciplines. Perhaps the most significant distinction exists in terms of the difference between the Food and Drug Administration's treatment of hearing aids as Class I medical devices, while cochlear implants are defined as Class III devices. Another point of divergence has been the number of publications in archival, peer-reviewed journals; implant papers have been steadily increasing during the past decade, while hearing aid papers have declined during the same period. The impact of these differences on the past, present, and future of hearing aid and cochlear implant research, technology, and clinical practice is discussed.
