Physics Students’ Conceptual Understanding of Electricity and Magnetism in Nine Years Basic Education in Rwanda

We investigate students’ misconceptions in electrostatics, direct current (DC) and magnetism which are important in electricity and magnetism. We developed and administered a multiple-choice questionnaire test to reveal students’ misconceptions related to charged bodies, lightning, electric fields, electric potential, forces, DC resistive electric circuits and magnets. This test aimed at obtaining quantitative information about misconceptions and was administered to 380 senior two students from Nine Year Basic Education (9YBE) Schools. The selected students have some experience with the new Rwandan secondary physics Competence Based Curriculum (CBC) that is currently under implementation. We find that senior two students have several common misconceptions related to these concepts. The data indicate that although students have some backgrounds on the subject matter, they still seem to believe that if the two charges are separated by a distance, a large-charged object exerts a greater force of attraction or repulsion on the small one. Considerable number of participated students held the misconception of considering current consumption in the resistor/bulb or the electrical devices in the circuits. They also believed that the battery was a continuous current source. The findings also revealed that students held a misconception that a bar magnet when broken into pieces, it is demagnetized. Moreover, a considerable number of participants hold the misconception that all metals are attracted by a magnet. Our study also revealed some of the statistically significant differences in terms of either gender or location of schools for some items.

Relationship Between Academic Library Workers’ Outlooks on Life, Personality, and Goal-Setting Behavior and Achievement

A Review of: Lo, L.S. & Anderson, A.M. (2020). Personal goal setting behavior and professional outlooks of academic library employees. Journal of New Librarianship, 5, 204-236. https://doi.org/10.33011/newlibs/9/21 Abstract Objective – To identify a correlation between academic library employees who set New Year’s resolutions and goal-setting behavior in professional contexts, and to explore practices, personal attitudes, and outlooks that influence goal-setting and goal-achievement Design – Non-experimental multiple choice questionnaire Setting – Online Subjects – 308 adult participants (over 21 years old) who work in academic library settings including staff, librarians, and administration Methods – The authors designed an online, non-experimental multiple choice questionnaire through Qualtrics. The authors distributed study invitations to multiple professional library listservs, though it is unclear which listservs were included and what geographic location was covered. The survey was available for roughly a month from February 1-26, 2016. The survey screened participant demographics to omit those under 21 years of age and all identifying information was removed in order to protect participant privacy. All participation was voluntary and participants who were interested in contributing to a follow-up research study were asked to share their contact emails. Main Results – Most participants (n=182, 59%) set no New Year's resolutions in 2015 and half (n=155, 50%) set no resolutions in 2016. When asked to explain, 23% noted that they hadn't considered setting resolutions in 2016, 9% did not prioritize setting goals, and 5% felt that they could not achieve their goals. Additionally, over 50% articulated other reasons including not prioritizing goal-setting for New Year’s, noting that setting goals around the academic year was timelier, and that some participants already had enough goals to achieve. In 2016, half of participants (n=153, 50%) set New Year’s resolutions. By far the most common resolution was physical fitness and healthy eating (n=64, 42%). About 19% set occupational goals including skill building, and 15% set emotional goals including cultivating optimism and mindfulness. When asked about goal-setting practices, 36% of the 2016 resolution setters described writing or typing out their goals, 59% shared their goals with others, and nearly 90% enacted changes in their daily routines in order to achieve their goals. 26 participants used all of the goal setting practices above. This group prioritized their top goals and felt confident about reaching those goals. Four participants did not practice goal-setting techniques, and also felt less confident about achieving their goals. 49% of 2016 resolution setters had somewhat optimistic outlooks, and 24% had very optimistic life outlooks. Of those with pessimistic life outlooks, nearly all believed it would be difficult to accomplish goals. Respondents who claimed to be very ambitious were likely to set occupational goals as their top goal. 81% of those in dean and director positions reported being very ambitious and 85% also reported being optimistic. All deans and directors felt confident about accomplishing their goals. For middle managers, 75% felt ambitious and 72% felt optimistic. Professional librarians were 66% ambitious and 72% optimistic. Conclusions – This study's findings align closely with United States national averages about the percentage of Americans who set New Year’s resolutions and achieve their goals. Data suggests some relationship between academic library workers’ outlooks on life and confidence in achieving their goals, as well as a correlation between goal setting strategies and achieving goals. The authors express optimism that 20% of participants who set New Year's resolutions chose to list occupational goals as their top goals, especially considering that resolution-setting comprises an incredibly broad array of options. The authors suggest that data can be used by academic library administrators to increase worker job performance, improve worker wellness, establish mentorship programs, and train workers to set attainable goals.

Focused educational intervention improves intern knowledge of perioperative patient blood management principles

A perioperative patient blood management (PBM) educational intervention was implemented for first year postgraduate doctors (interns) at the Royal Brisbane and Women’s Hospital (RBWH) following identification of a perioperative PBM training requirement. This quality improvement activity evaluated the effectiveness of this educational intervention in improving intern knowledge of perioperative PBM principles.A 15-question perioperative PBM focused multiple choice questionnaire developed from information attained from comprehensive, evidence and consensus-based guidelines regarding PBM practice was distributed to interns immediately before a compulsory perioperative PBM educational intervention and then again 5 weeks later. The perioperative PBM educational intervention was delivered every 10 weeks (five interventions in total) to a different group of interns each time. Statistical analysis determined significance between mean questionnaire score before and after the intervention.The mean pre-intervention score for correctly answered questions was 7/15 (SD 2.73) and mean post-intervention score was 9/15 (SD 2.99) (p=0.02). Categorisation of questions into core domains of perioperative PBM demonstrated intern scores for correctly answered questions improved in all domains following the educational intervention.Perioperative PBM education delivered through a dedicated intervention aimed to improve knowledge is associated with objective evidence of educational benefits for interns at RBWH. It is an effective strategy to enact PBM governance and bestow clinical guideline knowledge. This is important given the global health sector’s challenge to improve patient outcomes despite increasingly restricted funding and pressure on doctors to devote more time to service and less to teaching.

Determination of Organochlorine Residues in Cowpea (Vigna unguiculata L. WALP) From Selected Markets in Ibadan, Oyo State, Nigeria

Cowpea (Vigna unguiculata(L.) Walp) is one of the major stale plant protein food crops in Nigeria, but constantly being attacked by insects especially during storage. This has been a major production constraint which usually necessitated the use of synthetic pesticides and chemicals, but comes with the problems of high pesticides residues. In cowpea, only few information or research has been made as regarding the level of pesticides residues, therefore the objective of this study was to identify the awareness level and organochlorine insecticides residue presence trendy to cowpea grains. This study was carried out using a multiple choice questionnaire, in which three markets in Ibadan were selected as the case study due to their population and patronisation. The multiple choice questionnaire was used in getting information as regarding the pesticide used, method of application, duration of storage after pesticide application and level of awareness on the possible side effects of pesticides. Thirty samples of cowpea were collected from the selected three markets for residue analysis which was determined in an analytical laboratory using standard procedures. Data collected were analysed using descriptive statistics. Results showed that Fumigation, spraying and baiting were the mostly used method of application of pesticides and Aluminium phosphide, Betoxin and Quickphos were the mostly used pesticides during application. Higher percentage (56.67%) of the respondent store the food stuff for less than a month before exposing it to the market for sales, about 53.3% of the respondents shows their ignorance about the health hazard associated with pesticides. Organochlorine pesticide residues were detected in all the samples of cowpea grains examined with highest mean concentration of Endosulfan (0.7500 mg/kg 0.3508).

Willingness to Oppose Smoking among Pregnant Women

Even though smoking causes numerous threats to the developing foetus, it is the most common addiction in Polish women of reproductive age. Most studies undertake to examine the subject of opposing second-hand smoking or creating tools to reprimand pregnant women more effectively using a qualitative methodology. The study aimed to determine the profile of a pregnant woman who is willing to oppose the smoking of another pregnant woman. The research was conducted using an original multiple-choice questionnaire. The survey was shared on websites for expecting parents. Completed questionnaires were collected from 11,448 pregnant women. The Wald test for logistic regression was used for statistical analysis. Predictors of whether someone would draw another pregnant women’s attention to the fact that smoking is harmful were: intellectual work (OR 1.136; p-value 0.020) and currently being a student (OR 1.363; p-value 0.004), involvement of the child’s father (OR 1.377; p-value < 0.001), contact with social campaigns (OR 1.150; p-value 0.005) and knowledge about the consequences of smoking, as well as talking to the midwife about the harmfulness of cigarettes during pregnancy (OR 1.655; p-value < 0.001). Interpersonal relationships leave scope for public health interventions. It is worth enhancing criticism against smoking by specialists through information and education campaigns.

Environmental and social impacts of Aposelemis dam (Crete, Greece) according to lakeside population’s perception

The current research investigates the environmental and social impact observed today within the vicinity of the Aposelemis dam in NE Crete, Greece. The areas investigated consist of the two adjacent villages of the reservoir, namely; Potamies and Avdou village, respectively downstream and upstream of the dam structure and lake. The research was based on local stakeholders’ opinion, observation and perception, and was conducted through semi-interviews based on a detailed multiple-choice questionnaire format. The present investigation, as a continuation of our former research (presented at ICED2020), examines the environmental and social impact from a different perspective, and focuses exclusively on narrow dam region, attempting to explore current impacts as well as any observed differences between the upstream and downstream village. Provided the intense objections of local communities in the past, presently expressed local opinion is also investigated. The public acceptance of potential hypothetical scenarios concerning area’s future exploitation is moreover explored. The investigation concluded in groundwater resources quantity differentiation between the upstream and downstream area, and also in evaluation differences concerning opinion about everyday life, landscape and the project itself. Current investigation’s results set the basis for management towards sustainability, with emphasis on the environmental and social aspects of the term.

I think I understand: Investigating misconceptions regarding hypothesis test concepts among university students

Hypothesis testing is an essential tool among researchers and practitioners alike, with its use being being widely taught in many a programme at university level. However, past studies have shown that students hold misconceptions about important statistical concepts. This present study aims to reconfirm past efforts in this area, specifically in a South East Asian higher education institution. To test how well undergraduate university students’ understood key concepts in hypothesis testing, an online multiple choice questionnaire was deployed. The questionnaire also asked for students’ confidence ratings for each question, allowing us to distinguish the confident versus non-confident incorrect responses. A follow- up interview was then conducted to give deeper insights into reasons behind respondents’ errors. The main finding is that there are significantly more confident wrong answers than non-confident ones – highly indicative of the presence of misconceptions among respondents. Among them, students firmly believed that statistical inference procedures provide a direct calculational proof of the null hypothesis. Additionally, students have difficulty formulating correct hypotheses to be tested, and have poor grasp of the role of significance levels in hypothesis testing. Whether or not students were taking a quantitative-focused programme, or had prior statistics training, had no bearing on their score. Despite this, confidence ratings were significantly higher in both groups.
