A Web-Based Virtual Microscopy Platform for Improving Academic Performance in Histology and Pathology Laboratory Courses: A Pilot Study

Virtual microscopy (VM) has been utilized to improve students' learning experience in microscope laboratory sessions, but minimal attention has been given to determining how to use VM more effectively. The study examined the influence of VM on academic performance and teacher and student perceptions and compared laboratory test scores before and after VM incorporation. A total of 662 third-year students studying histology and 651 fourth-year students studying pathology were divided into two groups. The light microscopy (LM) group used a light microscope in 2014 and 2015, while the LM + VM group used the VM platform and a light microscope in 2016 and 2017. Four factors positively predict laboratory scores (R square, 0.323; P < 0.001): (i) the pathology course and test-enhanced learning, (ii) the VM platform and experience, (iii) medical students and lecture scores, and (iv) female students. The LM + VM group exhibited less score variability on laboratory examinations relative to their mean than the LM group. The LM + VM group was also associated with fewer failing grades (F grade; odds ratio, 0.336; P < 0.001) and higher scores (A grade; odds ratio, 2.084; P < 0.001) after controlling for sex, school, course, and lecture grades. The positive effect of the VM platform on laboratory test grades was associated with prior experience using the VM platform and was synergistic with more interim tests. Both teachers and students agreed that the VM platform enhanced laboratory learning. The incorporation of the VM platform in the context of test-enhanced learning may help more students to master microscopic laboratory content.     

A case analysis of Savecom: The role of indigenous leadership in implementing a business intelligence system

Evidence suggests that some factors can determine the successful implementation of strategic IT systems, i.e. Business Intelligence (BI). Although BI systems can provide companies with insights into their business operations they are painstakingly difficult to implement. Most frequently, employee resistance and change management related issues have been identified as the main causes of system implementation failure. This is particularly true for Chinese firms, where cultural nuances such as personalism and particularism serve as powerful barriers to ‘intelligence’ sharing. In this case study, we report how Chinese CEOs can overpower these restraining forces to facilitate implementation success. Preliminary evidence from our case firm suggests that a strong, committed and adaptive leadership style provides a basis for effective BI exploitation. Further, we also identify some strategic and tactical actions that Chinese CEOs can use to foster a knowledge sharing culture that is conducive to BI systems implementation.     

Enrichment of live unlabelled cardiomyocytes from heterogeneous cell populations using manipulation of cell settling velocity by magnetic field

The majority of available cardiomyocyte markers are intercellular proteins, limiting our ability to enrich live cardiomyocytes from heterogeneous cell preparations in the absence of genetic labeling. Here, we describe enrichment of live cardiomyocytes from the hearts of adult mice in a label-free microfluidic approach. The separation device consisted of a vertical column (15 mm long, 700 μm diameter), placed between permanent magnets resulting in a field strength of 1.23 T. To concentrate the field at the column wall, the column was wrapped with 69 μm diameter nickel wire. Before passing the cells through the column, the cardiomyocytes in the cell suspension had been rendered paramagnetic by treatment of the adult mouse heart cell preparation with sodium nitrite (2.5 mM) for 20 min on ice. The cell suspension was loaded into the vertical column from the top and upon settling, the non-myocytes were removed by the upward flow from the column. The cardiomyocytes were then collected from the column by applying a higher flow rate (144 μl/min). We found that by applying a separation flow rate of 4.2 μl/min in the first step, we can enrich live adult cardiomyocytes to 93% ± 2% in a label-free manner. The cardiomyocytes maintained viability immediately after separation and upon 24 h in culture.     

Appealing to Internet-based freelance developers in smartphone application marketplaces

The success of the iPhone has created the smartphone application marketplace as a new business model for freelance developers, with significant potential yields. Attracting and retaining these freelance developers is an important success factor for smartphone platform owners. Therefore, using the viewpoint of freelance developers, this study adopts a discovery-oriented approach to explore antecedents of intentions to maintain a relationship with an incumbent platform. In a relationship commitment sense, freelance developers sustain incumbent relationships because of their calculative and affective commitments. Interview data further suggest that monetary rewards, potential market demand, and switching costs relate to calculative commitment; perceived service quality, identification with the platform owner, and intrinsic rewards are antecedents of affective commitment. The findings from the literature review and field research together produce an integrative framework that offers key insights for the smartphone application market, which can help central actors understand how to retain their external partners.     

Student factors related to learning in biomechanics

The aim of this study was to identify the student behaviours and characteristics that are related to learning biomechanical concepts. The Biomechanics Concept Inventory (BCI) was given to 53 kinesiology majors before and after an introductory biomechanics class together with a survey of student behaviours to determine factors that assisted in learning. Analysis of scores from 49 students showed significant (P < 0.001) improvement following instruction. Variables that significantly (P < 0.05) and uniquely correlated with improvement were grade point average (r = 0.46) and student interest in biomechanics (r = 0.41). Thirty-one percent of the variance in learning could be accounted for by these two variables, with no distinctive associations with student behaviours like course reading, hours studying, and credits earned in maths and physics. However, grade point average was significantly correlated with several student behaviour variables. Consequently, student learning of biomechanical concepts is likely a complex phenomenon with individual learning related to variables that interact with student interest and overall academic ability.     

Does student learning style affect performance on different formats of biomechanics examinations?

Students' learning style preferences have been widely adapted into teaching and learning environments. The purpose of this study was to investigate the relationship between self-reported and assessed learning style preferences (visual, auditory, reading/writing, kinesthetic: VARK) on performance in different types of multiple-choice examinations (T1: text only format and T2: visual format) given in an introductory biomechanics class. Students who enrolled in three biomechanics classes at a state university were recruited to participate in the study. Ninety students (47 males and 43 females) completed a learning style survey and two types of examinations. Results showed that approximately half of the students were assessed and self-reported as kinesthetic for their preferred learning style. There was no significant difference in test performance between students who preferred visual and reading/writing learning styles (self-reported and assessed). These students demonstrated similar learning and comprehension of biomechanical concepts regardless of whether the test material was presented in their preferred sensory mode or not. Interestingly, female students' perceptions of their learning style preference may have a positive effect on the test results when the test is presented in their preferred format.     

Metacognition and Middle Grade Mathematics Teachers: Supporting Productive Struggle

Communicating mathematical ideas through writing, listening, and verbalizing allows students to think about how they “think” about mathematics. By focusing this communication on a reflection of how one thinks about mathematics, metacognitive writing engages students as mathematicians and learners. In this article we describe a professional development that we implemented with middle grade mathematics teachers focused on metacognitive writing as a tool to support productive struggle in the mathematics classroom. Thus, this practitioner article adds to the knowledge base on how to develop middle grade teachers metacognitive writing through engagement in productive struggle. Recommendations for practice are included.     

Monitoring Standards in Mathematics in Year 2: an 8 year cross‐sectional study

The National Curriculum was introduced into British primary schools in 1989 to raise standards of attainment, especially in the basic skills of English and mathematics. Other steps taken to raise standards included putting basic skills at the heart of the school curriculum and teacher training and publishing school performance tables to focus attention on standards. What has been the effect of these measures on children's mathematical attainments? This paper analyses the mathematics standards of eight cohorts of Year 2 children from five randomly selected primary schools within one Local Education Authority (LEA) (n = 1502) who had all done Mathematics 7 from 1989–1996. Examination of the means of the standardised mathematics scores for each cohort reveals evidence of stable standards in attainment over the 8 years. There are fewer over‐achievers than one would expect and this indicates that less children in this sample are doing really well than was the case when the test was standardised. Discussion centres on the cost effectiveness and utility of the National Curriculum, assessment procedures and the publishing of school performance tables in raising mathematical standards at Key Stage 1. The need for an effective system for monitoring educational standards throughout the UK is raised.
