Enhancing Numeracy Skills of Grade 3 Students Through Authentic Performance Tasks

Numeracy is the capacity to use mathematical ideas in all facets of life.It involves activities such as adding and subtracting numbers,counting,number recognition,solving number problems involving various operations,sorting,observing,identifying,and establishing patterns.It is one of the fundamental skills that students should have mastered by the end of their primary schooling.With the notable importance of mastery of numeracy skills,low achievement and performance of the learners were observed in this aspect.This study aimed in enhancing the numeracy skills of Grade 3 learners through authentic performance tasks.The variable in numeracy skills includes the four fundamental operations and problem solving.The quasi-experimental design was utilized wherein purposive sampling or non-randomized sampling was used.In this study,33 Grade 3 learners of Rizal Elementary School were selected to participate in the tests.Pre-test and post-test crafted by the teacher were the main instrument in the study.The result revealed that in the pre-test the learners obtained a mean percentage score(MPS)of 38.20%in four fundamental operations,which implied a non-numerate level.While in terms of problem solving,the learners obtained a MPS of 20.60%which is also in the non-numerate level.It has a grand mean of 29.40%with an interpretation of non-numerate level.In the post-test,it was observed that four fundamental operations have a MPS of 81.10%which is in average numerate level,while problem solving has a MPS of 76.30%with a grand mean of 78.70%with an interpretation of average numerate level.This implied that there is a significant difference between the pre-test and post-test in the four fundamental operations and problem solving.Thus,it can be concluded that the application of authentic performance tasks was effective to bridge the gap on numeracy skills.

The impact of task characteristics on the performance of nursing teams

Purpose:This study sought to examine the relationship between team task features and team task performance.Team task performance revolved around the team's technical knowledge and the technical core activities of the organization.On the other hand,team task characteristics include task identity,task significance,and task interdependence.Methods:This study involved a total of 300 nursing teams(1436 individual nurses)from seven state hospitals in Peninsular Malaysia.Data were collected using two sets of questionnaires which were initially distributed to 320 teams.One set was given to the team members and another set was given to the team leaders.Of the 320 sets sent out,300 sets were returned.Responses were then combined and aggregated to the team level to get the team's final score.Analyses of the hypotheses were done using Partial Least Squares(PLS)through assessment of the measurement and structural model.Results:Results from the path analysis revealed that of the three dimensions of team task attributes,only task significance was positively and significantly related to team task performance(β=0.076,P>0.05),while task identity(β=0.076,P>0.05)and task interdependence(β=-0.037,P>0.05)were found unrelated to team task performance.Conclusions:This study demonstrated that task significance is important to predict team task performance.Task significance reflects meaningfulness and nobility of tasks,thus elevate the desire to perform better in each assigned task.

Effect of Professional Designation on the Level of Task Performance by Community Health Workers in Enugu State

The study aimed at assessment of level of task performance of Primary Health Care Worker （PHCWs） according to their professional designations in selected Local Government Areas （LGA） in Enugu State. Descriptive survey research was used. 291 PHCWs were randomly selected from 9 LGA using a multistage method. Questionnaire was used to collect data and the instrument was validated using test-retest method with correlation coefficient of 0.79. The findings show that Community Health Extension Workers （CHEWs） performed higher than Environmental Health Officer （EVO） and Community Health Officers （CHOs） in the area of health education concerning prevailing health problems and method of control. They scored 66.09% as against 52.8% and 60.61% for EVO and CHEW respectively. The result showed that the professional designation has no significant effect （P 〈 0.05） on the level of task performed by PHCW and their levels of task performance were low. It was recommended that public Health physicians and Nurses should be involved in the PHC in Enugu State to provide the fight supervision to the PHCW.

Preliminary evaluation of the VIsion PERformance(VIPER) simulator

Background:This study evaluated the VIsion PERformance(VIPER)simulator’s ability to assess the functional visual performance in warfighters conducting civilian and military tasks.Methods:Thirty service members,aged 25–35 years old with a best corrected distance visual acuity(VA)better than or equal to 20/20 or logarithm of the minimum angle of resolution(logMAR)0.00,were randomized to locate and identify road signs and mock improvised explosive devices(IEDs)under either daytime conditions or with infrared imagery,with(cc)and without(sc)wearing their habitual correction.Participants also underwent binocular uncorrected(UDVA)and corrected(CDVA)visual assessment,refraction,contrast sensitivity testing and wavefront aberrometry.Results:The mean age was 28.47 years.The manifest spherical equivalent was–3.16±1.75 diopters(D),the UDVA in both eyes(OU)was logMAR 0.83±0.47,and the CDVA OU was–0.11±0.06.For VIPER,the mean difference in the detection distance(DD)for road signs ccDD vs.scDD was(76.7±52.8)m(P<0.001).The average difference in identification distance(ID)ccID vs.scID was(13.9±6.3)m(P<0.001).The mean accuracies were 83.5%and 27.9%for cc and sc,respectively(P<0.001).The regression analysis indicated that a 1.6 m change in the distance accounts for a 1%change in the accuracy(P=0.002).Without correction,a 4.1 m change accounts for a 1%change in the accuracy(P<0.001).The average IED ccDD was(29.9±8.2)m,and that for scDD was(13.2±13.6)m(P<0.001).The average IED ccID was(32.2±6.2)m and that for the scID was(7.4±10.3)m(P<0.001).The mean IED identification accuracy was 46.7 and 11.4%for cc and sc,respectively(P<0.001).Conclusions:The preliminary results reflect VIPER’s ability to assess functional visual performance when detecting and identifying signs and IEDs.Furthermore,VIPER is able to detect performance changes with and without correction.

Authoritarian leadership and task performance:the effects of leader-member exchange and dependence on leader

This study examines how and when authoritarian leadership affects subordinates’task performance.Using social exchange theory and power dependence theory,this study proposes that authoritarian leadership negatively influences task performance through leader-member exchange(LMX).This study further proposes that the effect of authoritarian leadership on LMX is stronger when a subordinate has less dependence on a leader.A two-wave survey was conducted in a large electronics and information enterprise group in China.These hypotheses are supported by results based on 219 supervisor-subordinate dyads.The results reveal that authoritarian leadership negatively affects subordinates’task performance via LMX.Dependence on leader buffers the negative effect of authoritarian leadership on LMX and mitigates the indirect effect of authoritarian leadership on employee task performance through LMX.Theoretical contributions and practical implications are discussed.

Creation and Evaluation of a Multi-sensory Virtual Assembly Environment

The multi-modal information presentation, integrated into the virtual environment （VE）, has potential for stimulating different senses, improving the user＇s impression of immersion, and increasing the amount of information that is accepted and processed by the user＇s perception system. The increase of the useful feedback information may reduce the user＇s cognitive load, thus enhancing the user＇s efficiency and performance while interacting with VEs. This paper presents our creation of a multi-sensory virtual assembly environment （VAE） and the evaluation of the effects of multi-sensory feedback on the usability. The VAE brings together complex technologies such as constraint-based assembly simulation, optical motion tracking technology, and real-time 3D sound generation technology around a virtual reality workbench and a common software platform. The usability evaluation is in terms of its three attributes： efficiency of use, user satisfaction, and reliability. These are addressed by using task completion times （TCTs）, questionnaires, and human performance error rates （HPERs）, respectively. Two assembly tasks have been used to perform the experiments, using sixteen participants. The outcomes showed that the multi-sensory feedback could improve the usability. They also indicated that the integrated feedback offered better usability than either feedback used in isolation. Most participants preferred the integrated feedback to either feedback （visual or auditory） or no feedback. The participants＇ comments demonstrated that nonrealistic or inappropriate feedback had negative effects on the usability, and easily made them feel frustrated. The possible reasons behind the outcomes are also analysed by using a unifying human computer interaction framework. The implications, concluded from the outcomes of this work, can serve as useful guidelines for improving VE system design and implementation.

Effects of Local-Lag Mechanism on Task Performance in a Desktop CVE System

Consistency maintenance is a kernel problem in Collaborative VirtualEnvironment (CVE) research. The approaches used in Networked Virtual Environments (e.g., DRalgorithm) could not be used in CVEs, for they could not prevent short-term inconsistency.Therefore, local-lag mechanism has been proposed to eliminate short-term inconsistency in CVEs.Choosing a proper lag value is a key problem in local-lag mechanism. This paper studied the effectsof lag value (0ms-900ms) on task performance in a desktop CVE system. Experimental results indicatethat the effect of lag value on task performance is not linear. The effect could be separated intofour segments by three dividing points: 150ms, 300ms and 600ms. Lag has no effect on taskperformance while ranging from 0ms to 150ms. From 150ms to 300ms, lag slightly affects taskperformance. Lag deteriorates task performance seriously while ranging from 300ms to 600ms. When lagis longer than 600ms, the task cannot be accomplished sometimes.

Theory and Professionals： Impact of HRM on Economy

Research topic of this paper includes importance of theoretical knowledge on performance of firms＇ professionals. Research question is how theory affects the performance. Answer might become thorough competence of professionals and task performance. With this sense, two case studis are obtained from Drucker＇s works （2009; 2015）. Therefore, research method covers case study approaches. Furthermore, firms produce national GDP in an economy. There are several functions in firm management, and managers operate those functions. They are logistics, supply, stock, finance, accounting, marketing, production, etc. All have managers such as accounting manager, finance manager, marketing manager, etc. Performance of managers is crucial to fLrm performance. Because performance of managers might become one determinator of firm performance. Therefore, HRM may have an impact on GDP through managers. Because productions and sales of firms affect GDPs on an economy. Moreover, professionals or managers must have theoretical knowledge in their field. Because theoretical knowledge increases their performance at work. In conclusion, study reveals that managers may have impact on firm performance; and theory may increase task performance of employees.
