Biodiversity is related to a global problem: its destruction, a fact supported by scientific authorities. It is not trivial that educational dimension has been contemplated as one of the strategies for its conservation. Since 1992 global initiatives such as the Convention on Biological Diversity postulates concepts that linked education and nature conservation. The main objective of this research work is to test the level of assimilation of extracurricular scientific knowledge by primary school pupils. The method chosen for the content was, on the one hand, a master class intervention with an interactive presentation on a digital whiteboard. Third cases were chosen. Each case consisted of a presentation of the current status of a species of fauna present in Spain. On the second part, students were asked to write an essay and to illustrate the experience during the presentation. Regarding the essays, students showed that they were more attracted to the first species that was presented (Iberian lynx) in a proportion of over 45% of cases. The “Endangered species” concept appeared in more than 77% of the texts reviewed. In terms of drawings, almost 55% of the responses seem to devote more attention to the second species described (Testudo graeca). An attempt was made to offer rigorous, structured information related to different aspects of natural reality in order to contemplate the broadest possible vision. The example of an instructional intervention presented here aims to be an alternative to other transmissive teaching models. Likewise, the linking of abstract concepts with socio-cultural reality proved to be a successful strategy to reinforce knowledge about natural biodiversity, endangered species or threat factors.

In this article, our investigation to study squeezing and statistical properties of the light by a two mode sub harmonic generator coupled to thermal reservoir via a single port-mirror. The equation of motion answers are then used to calculate the mean photon number, photon number variance, and quadrature variance for two mode cavity light. However, we have found that the degree of squeezing is indeed affected by the present of thermal light. The mean photon number of the system under consideration increases with increasing $\stackrel{-}{\mathrm{n}}$.

In this article the investigation of squeezing and statistical properties of light resulting by a non-degenerate three-level laser with the parametric amplifier and coupled to a thermal reservoir have been occurred. With the aid of master equation, stochastic differential equations were obtained. Applying solutions of resulting differential equations, quadrature variance, the mean and variance of photon number, the photon number correlation are calculated. However, the two-mode driving light has no effect on the squeezing properties of the cavity modes. On the other hand, parametric amplifier and thermal reservoir increase the mean and variance of photon number. Furthermore, employing the same solutions, we also obtain anti normally ordered characteristic function defined in the Heisenberg picture. For a linear gain coefficient of (A = 100), for a cavity damping constant of K= 0:8, µ = 0 and for thermal reservoir th = 0, the maximum intra cavity photon entanglement is found at steady state and at threshold to be 60%.

Bead jewellery is common in all Ghanaian communities. Bead jewellers are well-known for their important bead jewellery production and have advanced to the Master craft level. The industry can be utilized if the industry's difficulties are discovered and remedied. The study area for the research includes Ghana's Eastern, Ashanti, and Greater Accra Regions. The study's population included bead jewellers, bead jewellery firms, bead dealers, bead aficionados, clients, and bead makers. With a sample size of 30, data was gathered mostly through direct observations, interviews, and document reviews. The study went over the procedure for securing land for a bead jewellery workshop. According to a survey conducted by the Ghanaian Chamber of Commerce and Industry (GCCII), Ghanaian bead jewellers should use qualified designers. Cost pooling in legal services, accounting, and consulting is likely to save money.

Making students efficiently and flexibly understand and master the knowledge of biological/biomedical sciences by prompting active learning and critical thinking and making biomedical science courses form an integrated system are critical for more successful and effective student education, future and career. However, the current biological/biomedical education system worldwide tends to produce graduates best suited for postdoctoral training, and academic careers, in highly specialized areas. Many institutions worldwide currently favor densely packed curricula with fast-paced instruction focused on detailed subject matter, with little room left for skill training in both active learning and critical thinking, creative problem solving, professional skills, putting what was learned into a larger context that creates meaning, and teaching students with different learning styles, despite their significance. In this article, we will discuss the current defects in biological/biomedical science education and the need to reform biomedical science teaching and education. We will also describe some suggestions and approaches to improve biological/biomedical science learning and education, including the establishment of a more effective learning/teaching repository.

Qualitatively, the study focused constructivist research paradigm. A case study research design was adopted for the study. The study population comprised all six (6) Social Studies teachers, the headmaster and the School Improvement Support Officer (SISO). Purposive and convenient sampling techniques were used to select the participants for the study. The main instrument for data collection was a semi-structured interview guide and observation protocol. The data were analysed using the interpretative technique based on the themes arrived at during the data collection from the semi-structured interview. The study revealed that multimedia usage is a quality enhancer in educational settings for teaching Social Studies concepts. It also indicated that teachers perceived their incompetence when using technology as they feel less in control of their classes and are unlikely to explore new possibilities that utilise technology when planning their lessons. They learn the theoretical aspect and practice and perceive the teacher’s role in the classroom changes from an instructor to a facilitator, which changes the teaching method to student-centred (constructive methodology) which aids content absorption by the learner through learning by doing. The study also indicated that teachers perceived their incompetence when using technology as they felt less in control of their classes and were unlikely to explore new possibilities that utilised technology when planning their lessons. It is recommended that the Ministry of Education and National Teaching Council collaborate with Ghana Education Service to set up Social Studies training centres in all the district capitals equipped with competent staff to periodically organise in-service training for teachers to build their capacity on how to pedagogically incorporate multimedia resources in their instructions to improve students learning outcomes.

This study was conducted to assess the effect of visual aids in teaching science lessons in the Junior High Schools (JHS) in Ghana. The quantitative research method was chosen for this study. A Purposive sampling technique was used to select 245 JHS 2 students and seven (7) science teachers (1 from each selected school) from seven (7) selected JHS in Enchi Municipal under Aowin District in the Western North Region of Ghana. The main instrument for data collection for this study was a questionnaire and a test. The data analysis was done using the SPSS statistical package, where a questionnaire was analysed to determine the frequency and percentages of responses from selected science teachers and test analysis was done using a Pair Sample t-test to determine any significant differences between pre-test and post-test of the respondents. This study found that the use of visual aids in teaching science encouraged learners to develop interest and participate actively in the lessons which resulted in improved student performances and developed interest during the lesson. The study recommended that Ghana Education Service (GES) and headmasters at the JHS should endeavour to provide enough visual aids for their schools to enable the teaching and learning of science better and to be learner-centred, practical learning and for learners to develop interest and positive attitude towards learning science to improve performances and appreciate the need to learn science to the highest level for self-development and the development of the country.

The purpose of this study was to examine the empirical analysis of lexico-grammatical features used in the rhetorical structure of the Statement of the Research Problems of Master of Philosophy theses in the Faculties of Arts and Education at the University of Cape Coast, Ghana. Qualitatively, content analysis was adopted for this study. Theses from the Faculty of Arts and the Faculty of Education at the University of Cape Coast were selected for this study. These theses were selected from 2012 to 2022 academic years to ensure currency in terms of the stipulated lexico-grammatical features used in the statement of the research problem. Purposive and simple random sampling techniques were used to select the university, two faculties (Faculty of Arts and Faculty of Education) and postgraduate theses for the study. The two faculties were purposively sampled. Eighty (80) theses were simple randomly sampled (Forty (40) theses each from the Faculty of Arts and the Faculty of Education). The main instrument used for data collection was content analysis. The data was analysed by the use of the interpretative technique based on the themes arrived at during the data collection of the statement of research problem from the post-graduate theses. The study indicated that integral citation was dominant in SRPs from the Faculty of Arts theses whereas non-integral citations were rather dominant in SRPs from the Faculty of Education theses. The use of adverbials to boost these claims was also found in only the SRPs from the Faculty of Arts theses. The use of hedging devices in SRPs from both Faculties to indicate a gap, and the use of simple noun phrases such as “the problem” and “the need” were mostly used to categorically state the research problem. It is recommended that a comparative study of theses in the two faculties in another university in Ghana be undertaken to identify how similar or otherwise the rhetorical structure and the lexico-grammatical features of the SRPs written by postgraduate students in the two faculties will be.

Background: Oral health plays an important role in maintaining life functions and quality of life. Periodontal disease can vary with respect to bacterial etiology, host response, and clinical disease progression. A key role of genetic effects has suggested distribution of lesions and severity of destruction in each individual. Many diseases, particularly digestive disorders, cancer, and infection, show preferences among the ABO blood types. Knowledge of blood groups and their association with oral diseases is very important, as it may help in early diagnosis and treatment strategies‏. Objectives: The study aimed to investigate the distribution of patients with oral and dental health problems according to age, regions, Socio-demographic Variables, and blood groups in the Tripoli region. Material and Methods: The present study was conducted on 200 patients with oral and dental health problems attending six medical centers in Tripoli region from the 01^st March 2022 to the 01^st June 2022. Also, 100 healthy individuals without any oral and dental health problems or any other diseases were recruited as a control group. This study was approved by the Research and Ethical Committee of the medical centers and Libyan Academy of graduate studies. One ml of venous blood was withdrawn from each participant in the study for determination of blood groups. The data were compared using Chi-Square using SPSS Statistics for Windows, Version 25. Results: The results showed that the mean age of the patients was 43.03±13.82 years. The higher distribution of patients was 58 patients (29%) in the age group (26-35) years while the lower distribution was 10 patients (5%) in the age group (66-75) years. The distribution of patients according to the region were 81.5%, 13%, 4%, and 1.5% in Tripoli, South Tripoli, West Tripoli, and East Tripoli, respectively. The Distribution of patients according to occupation were 4.5% Students, 30% Housewives, 10.5% Employers, 12.5% Teachers, 14% Nurses, 7.5% Doctors, 12.5% Laboratory Technicians and 8.5% Freelance workers. The distribution of patients according to levels of education were 23.5% Pre-Secondary, 19% Secondary, 46% Bachelor's or equivalent, and 11.5% Master's or equivalent. The distribution of patients according to marital status were 26% single and 74% married. The distribution of patients according to oral and dental problems were 5% with bridge, 8% with missing teeth, 86% with dental caries, 63.5% with bleeding of gum, and 25.5% with swelling of gum. The degrees of gingival erythema among patients were 36.5% mild, 38% moderate, and 25.5% severe. The degrees of gingival inflammation among patients were 36% mild, 38.5% moderate, and 25.5% severe. The distribution of A, B, AB, and O blood groups showed a significant (P=0.000) difference between healthy individuals and oral and dental health problems among patients that, were 54%, 12%, 4%& 30%, and 21.5%, 9%, 3.5% & 66%, respectively. Also, the distribution of A⁺, A^-, B⁺, B^-, AB⁺, O⁺, and O^- blood groups showed a significant (P=0.000) difference between healthy individuals and patients with oral and dental health problems that, were 49%, 5%, 10%, 2%, 4%, 25%, & 5%, and 18%, 3.5%, 8%, 1%, 3.5%, 60%& 6%, respectively. But, the distribution of Rh⁺ and Rh^- blood groups showed a non-significant (P=0.695) difference between healthy individuals and patients that, were 88% & 12%, and 89.5%& 10.5%, respectively. Conclusion: It can be concluded that the mean age of the patients with oral and dental health problems was 43.03 years and the higher distribution of patients was in the age group (26-35) years. The higher distribution of ABO blood groups was O blood group among patients especially O⁺ blood groups. The distribution of Rh+ and Rh- blood groups were showed a non-significant difference between healthy individuals and patients with oral and dental health problems. Further studies are needed to confirm these results.

A three-level laser with an open cavity and a two-mode vacuum reservoir is explored for its quantum properties. Our investigation begins with a normalized order of the noise operators associated with the vacuum reservoir. The master equation and linear operators' equations of motion are used to determine the equations of evolution of the atomic operators' expectation values. The equation of motion answers are then used to calculate the mean photon number, photon number variance, and quadrature variance for single–mode cavity light and two–mode cavity light. As a result, for γ=0, the quadrature variance of light mode a is greater than the mean photon number for two-mode cavity light. As a result, for the two-mode cavity light, the maximum quadrature squeezing is 43.42 percent.

This study adopted both qualitative and quantitative research approaches. The study population covered the house masters and mistresses, students, teachers, grounds prefect and WASH coordinators in the Assin Manso, Adankwaman, Nyankomasi Ahenkro, Assin Nsuta Agric Senior High Schools in the Assin South District. Simple random and purposive sampling techniques were employed to select respondents for the study. The sample size for the study was 216. Two hundred students (200) were selected from the four senior high schools in the District, that is, 50 students from each school, four (4) grounds prefects, one from each school, eight (8) house masters /mistresses, that is, two (2) from each school, and four (4) WASH coordinators one each from a school. The main tools used for the study were semi-structured questionnaires, interview guide and observation checklist. Data analysis was done using both quantitative and qualitative methods. Descriptive data were analysed qualitatively and emerging themes from the data were obtained and categorised and then interpreted through the interview guide with observation checklist digital data such as photographs were used to bring out some aspects of the schools’ surrounding. On the other hand, quantitative data were collected using questionnaire on the numbers of schools and WASH facilities, and analysed using SPSS. The study indicated that the failure of the school administration to maintain the WASH facilities will eventually lead to their breakdown, thus making it difficult for the students to use them. The study also revealed that the poor participation by the communities in the provision and maintenance of the WASH facilities stems from the fact they do not get any direct benefit from the schools. It is recommended that, in promoting WASH facilities in the schools, administrators must include maintenance of the facilities in their provision to ensure their long-term use, other than that the facilities will break down, and resources will have to be mobilized again to repair them or provide new ones. It is also recommended that, Rules and regulations concerning the use and maintenance of WASH facilities should be made by school administration and copies given to the students to guide them as they use the facilities.

The purpose of the study was to assess teachers’ knowledge in integrating affective domain in teaching and learning of Social Studies lessons in the junior high schools in Aowin Municipality. A quantitative approach and survey research design used the study. The study population constituted Social Studies teachers in the 40 Junior High Schools in the Aowin Municipality of the Western North Region of Ghana. Simple random and convenient sampling techniques were used to sample the respondents of the study. The sampling technique was to ensure the representativeness of the sample. The study used structured questionnaires to collect the data. Descriptive statistics in the form of percentages was used in this study. SPSS was used to analyse the data. The study concluded that the Social Studies teachers have some level of knowledge of the principles of developing affective test items. The study also indicated that Social Studies teachers in the study area can define affective objectives in behavioural terms and have some level of knowledge of the principles of developing affective test items, they do not teach the affective domain. It is recommended that, Coordinators for junior high schools and the headmasters (academic) should ensure that affective objectives are inculcated in the general lesson objectives of Social Studies teachers. Intensive in-service training should be ran for Social Studies teachers to equip them on the formulation of affective objectives. It is also recommended that in service training should be organised by the education directorate in the municipality to train teachers in the teaching of lessons involving the affective domain. The headmasters, as well as the coordinators for junior high schools, should monitor whether teacher’s qualification reflect in the teaching of the social studies lessons that involve the affective domain.

The purpose of the study was to examine teachers’ intrinsic and extrinsic motivation in leadership for learning (LfL) in Aboabo Educational Circuit (AEC) in the Ashanti Region of Ghana. The study employed an explanatory correlational quantitative research approach. The population of the study consisted of ten (10) headmasters and forty-two (42) teachers in public Junior High Schools (JHS) of Aboabo Educational Circuit. Convenience, purposive and quota sampling techniques were used to select schools, headteachers and teachers for the study. The main instrument used for data collection was questionnaire. Spearman’s rank order correlation was used to analyse research hypotheses 1 and 2; Wilcoxon test was also used to analyse research hypothesis 3. The study revealed that intrinsic teachers’ motivation is negatively related to Leadership for Learning within the AEC. The study also indicated that extrinsic teachers’ motivation has an insignificant positive association with Leadership for Learning within the AEC. The study also concluded that there is a significant difference between Intrinsic Teacher Motivation (ITM) and Extrinsic Teacher Motivation (ETM) in AEC. Therefore, ITM and ETM plays minimal or no role within AEC. It is recommended that the officers within AEC must not focus only on high pupils’ academic achievement at the detriment of taking appropriate steps to make classroom teaching interesting and attractive. It is also recommended that School Management Committees within AEC must in their small way do their best to boost the extrinsic motivation of teachers within the circuit.

The purpose of the study was to investigate the effect of computer-assisted instruction approach to the teaching and learning of photosynthesis on the performance of second year Senior High School (SHS 2) Biology students in science. The design for the study was a quasi-experimental research. This study was carried out in Sefwi Wiawso SHS and Asawinso SHS all at Sefwi Wiawso Municipal Assembly in the Western North Region of Ghana. They are all mixed institution. The purposive sampling techniques was used to schools, classes and students for the study. One-hundred one (101) electives biology participants were purposively selected, they consist of SHS 2 Science of (55) fifty-five students from Sefwi Wiawso SHS and SHS 2 Home economics of (46) forty-six students also from Asawinso SHS. The third years were not selected because they were preparing to write their WASSCE. The main instrument for data collection was questionnaire. The study collected only quantitative data and employed quantitative method of data analysis. Data obtained from participants in both experimental and control groups on the Test 2 were analysed statistically using independent-measures t-test. The independent-measures t-Test was used to investigate whether any differences existed between experimental and control groups’ mean scores on the Test 2. The study further revealed that computer-assisted instructions gives feedback to learners to have the opportunity to master computer-assisted instructional package tool used. It is recommended that, computer-assisted instruction method should be encouraged in many Biology classes in Wiawso Municipal Assembly, since it gives students opportunity to see links between concepts, summarise and organise their works, thoughts logically and sequentially. Both genders must be encouraged to use computer-assisted instruction method to studying Biology.

The purpose of this study was to examine the challenges faced by School Improvement Support Officers, Headmasters and teachers during the instructional supervision of Social Studies lessons in the public basic junior high schools in the Aowin Municipality of the Western North Region of Ghana. The study adopted sequential explanatory research design. The population of the study included School Improvement Support Officers (SISOs), Headteachers and teachers of selected from Junior High Schools in Aowin Municipality of the Western North Region of Ghana. Purposive sampling technique was used to select ten (10) SISOs and sixty (60) Headteachers in the Aowin Municipality. Stratified, simple random and quota sampling technique was used to select one hundred and twenty (120) teachers for the study. The two main instruments used for data collection were questionnaire and interview guide. The quantitative data entry and analysis was done by using the SPSS version 22 software package. The data was edited, coded and analysed into frequencies, percentages with interpretations. The qualitative data was analysed by the use of the interpretative method. The study revealed that headteachers and School Improvement Support Officers (SISOs) faced challenges such as ; Poor road networks which affected planned supervision; Inability of district directorate to promptly, firmly and fairly acts upon reports from instructional supervision activities from supervisors; Lack of logistics for regular supervision; Insufficient up-to-date knowledge and skills for organizing instructional supervision; and Financial constraints. To overcome the challenges and poor supervisory techniques by headteachers and SISOs, it is recommended that these personnel should be oriented on modern trends in instructional supervision, provided with adequate and sufficient materials for instructional supervision, sufficient funds provided for organizing instructional supervision, the municipal directorate should fairly and firmly implement reports on instructional supervision activities and there should be good motivation package for supervisors to enable them to effectively perform their duties.

Background and aim: Developing clinical skills and its assessment is one of the most important components in nursing education which prepares the student for the reality of practice. Objective structured clinical examination (OSCE) is extensively used and widely accepted by nurse educators across the globe to assess the competency skills of nursing students. The present study aimed at identifying the attitude and perceptions of faculty, and exploring their feedback and experience in conducting OSCE as an assessment tool. Methods: A triangulation research approach was used with convenience sampling. Data collection was carried out using questionnaires and semi-structured interviews. Participants were ten faculty members who were involved in conducting OSCE for students. Results and conclusion: Most of the faculty felt that OSCE reflected the skills of delivery of safe patient care, and the structure reflected mastery of knowledge and skills, which are related to course objectives. OSCE was regarded by the faculty as a consistent, reliable, valid, and objective measure to assess students’ performance and to improve students’ confidence in clinical skills. Concerns were raised about a high level of stress in students, the time required for the proper performance of tasks, OSCE scenarios lacking real-life situations in assessment, and the need for repeated practice and intensive mock training sessions. The applicability of OSCE in terms of limitations in human and material resources with a large number of students would necessitate rethinking in developing other assessment strategies to improve the overall process.

Imagine a consumer financial services company with 20 million customers. Its sales and marketing organizations collaborate across product lines, deploying hundreds of marketing campaigns each quarter that aim to increase customer product usage and/or cross-buying of products. Each campaign is based on forecasts of customer responses derived from predictive models updated every quarter. The goals of these models are to achieve large return on investment ratios and to maximize contribution to local profit centers. What’s important is that their modeling is based only on data created, curated and maintained by these marketing organizations. The difference today is that the modeling is no longer based solely on a small number of response-determined variables that are constantly assessed in terms of importance. A quarterly campaign update generates hundreds of statistical models — involving campaign responses, purchase-lag time, the relative magnitude of the direct effect, and the cross-buying effects — using thousands of variables, including customer demographics, life stage, product transactions, household composition, and customer service history. It’s a network of models, not just a table of variable-by-residual importance values. But that’s only part of the story of data products. The predictive modeling utilized by these campaign plans is based on analytics and data preparation, which are data products in their most diminutive form. These products would be even more elementary were they not crafted quarterly by highly skilled, experienced modelers using advanced software and processes. Most companies have enough data to create models that contain not simply hundreds of variables, but thousands, so that the focus can return to information instead of data reduction. These models largely replace the internal econometric models previously used to produce advanced forecasts in the absence of campaign modeling. People used these forecasts to simulate ROI and contribution forecasts for the planned campaigns. In the old days, reliance on econometrically forecast ROI-guideline contribution values reduced the reliance on the marketing campaign modelers because of a lack of trust in their predictive ability.
