The conventional versus a constructionist Scratch programming and first-year students' achievements in higher education classes: experimental data.
No full textGlobally, learning or teaching the first programming (popularly called CS1) remains a significant educational challenge. Indicators such as CS1 students' engagement, failure and attrition rates, and lack of diversity, continue to show the need for innovating the learning or teaching of novice computer science students. To ease initiating novices to programming, Scratch, a visual programming language, has become a staple of K-12 CS1 classes.
As outcomes of a research project aiming to explore a constructionist Scratch pedagogy with novice CS students in higher education, we present these datasets. In the research lasting two successive academic sessions, we conducted two quasi-experimental studies involving four intact CS1 classes in selected public polytechnic in the north central Nigeria. In each study, we randomly assigned the classes to the experimental and control groups, constituting the constructionist Scratch and the conventional CS1 classes, respectively.
Instruments for collecting data include a student profile questionnaire, a pretest, and posttest. Sequel to ethical clearance and permission from the selected schools, we conducted each study during the first semester of each academic session, in the first seven to eight weeks. During the first to second week, we administered students who consented to take part with the questionnaire and the pretest. Learning or teaching in the two classes lasted six weeks. Then both classes took the posttest. An independent CS educator who is not part of this research marked all the achievement tests, following a rubric prepared by the first author. To strengthen the research design and the possibility of arriving at valid causal evidence, we employed a Coarsened Exact Matching (CEM) algorithm to generate matched samples of experimental and control data, which we used in the analysis.
Data presented here includes the raw, unmatched and matched experimental datasets from both studies. A researcher can make use of the data:
To explore if some background variables not addressed in the original research may moderate CS1 students' achievements. For instance, their prior achievements in mathematics, physics, or English.
To uncover some interesting patterns using machine learning algorithms.
To validate the outcome of the original experiment by using the unmatched, matched or newly generated matched samples.
The authors welcome further research collaborations in using the data or the accompanying research instruments.

Clinical Pattern and Management of Keloids in Black Poplulation
No full textObjective: To present the clinical pattern, treatment approach and outcome of keloid care in our clinical practice.Design: A retrospective study.Setting: Obafemi Awolowo University Teaching Hospital, Ile-Ife, Southwestern Nigeria.Subjects: All patients presenting with keloids during the study periodIntervention: The pattern of presentation, modalities of treatment and outcome of care as well as complications and recurrences were documented.Results: Seventy – six patients were studied. Equal male to female ratio. Their ages ranged from 1-75 years with a modal age of 24 years. Lesions presented for treatment were most commonly located in the head and neck region. Itching was the most common symptom. Combination therapy by surgical resection, intralesional triamcinolone injection and superficial radiotherapy was the most common modality of treatment and gave the least rate of recurrence.Conclusions: Combination therapy gave the best outcome in our practice
Constraints to feedback provision on forestry-related technologies
No full textThis paper ascertained the constraints to feedback provision on forestry-related technologies. Interview schedule was used to elicit information from 163 randomly selected respondents. Descriptive (frequencies, percentages) and inferential (Chi square and Ordinary Least square regression) statistics were used to analyse data collected for the study. Chi square statistics shows significant relationship between gender, age, marital status, number of wives, education and constraints to feedback provision. The major constraints that were identified as affecting feedback provision on forestry related technologies include illiteracy, unstable government policy, busy schedule of extension agents, busy schedule of researchers, low ratio of extension agents to farmers, poor infrastructure. The regression result showed R2 value of 0.67 which is an indication that 67 percent of constraints to feedback provision were explained by other independent variables and the multiple R of 0.82 shows a very strong correlation between the independent and dependent variables. Only farm size (t-value = -3.31,
The use of large bilobed flap in the management of cheek defect: a case report
No full textIntroduction: bilobed flaps are versatile reconstructive tools which have been used extensively in the management of nasal, shoulder and neck defects. Although its use in the cheek has been reported, it is uncommonly utilized.Case report: This is a case report of a 22yr old lady with traumatic left cheek defect managed with the use of a large bilobed flap.Result: The Post-operative outcome was satisfactoryConclusion: Large bilobed flaps should be considered when reconstructing cheek defects.Key Words: Bilobed flap, cheek defect

Farmers demographic characteristics, awareness and perception of the relevance of livestock technologies in Oyo State
No full textThis paper analyses the perception of the relevance of livestock production technologies by farmers in Oyo state. A multistage sampling was employed and 120 respondents were used for the study. Percentages and chi-square analysis were employed to analyze the data. Findings revealed that majority of livestock farmers (62.5%) recorded a low perception score. Chi-square analysis of demographic characteristics showed that level of education, farm size, and age have significant relationship with perception of livestock technologies (X2 = 13.6 p < 0.05, X2 = 29.02 p < 0.05 and X2 = 22.07 p <0.05 respectively) while gender has no significant relationship with perception of livestock technologies (X2 = 0.75 p > 0.05). The study concludes that livestock technologies would be more result-oriented if adequate consideration is given to the demographic characteristics and perception of farmers among others which will in turn help the farmer in making decision to adopt. Keywords: Demography, livestock, technology, awareness, relevanc
Lip reconstruction after major tissue loss
No full textBackground: Major defects of the lips are challenging to the reconstructive surgeon. The goals in treating total or near total lip defects are reconstruction of the skin, the muscle, the mucosal lining, maintenance of oral competence and an acceptable cosmetic appearance. Six patients with major lip defects from various causes as seen in our practice were successfully managed are discussed. Case reports: Two patients had major lower lip loss following gunshot injuries, one patient had major upper lip defect following blast injury. Two other patients had post excision defects for lip malignancy while the lasthad a congenital midline defect of the upper lip and primary palate. All patients had lip reconstruction using local flaps, no flap loss was recorded and the postoperative appearance was acceptable to them. Conclusion: Functional and aesthetic outcomes appear acceptable when local flaps are employed in lip reconstruction in this black population even with major lip defects.Key words: lip reconstruction, major lip defect
Informed Consent In Surgery: An Audit Of Practice In Ile-ife, Nigeria
No full textObjectives: This study was conducted to assess patients\' knowledge of their diagnoses and proposed surgical procedures before giving consent for such procedures in the various surgical units of Obafemi Awolowo University Teaching Hospitals Complex, (OAUTHC), Ile-Ife. Materials and Methods: A structured questionnaire was administered to 80 consecutive patients who had just undergone an elective major surgery in general surgery, gyneacology, orthopaedics and surgical subspecialty units of the hospital.
Results: Sixty patients (75%) gave consent themselves, while other consents were obtained from close relations. Thirty-seven (46.25%) respondents were informed of the diagnoses and procedure by the unit consultants but no consultant was involved in the completion of the consent form. Seventy-five (93.75%) respondents had a knowledge of the diagnoses, 68(85%) understood the procedure but only 21(26.25%) knew any alternative to the procedure, 29(36.25%) knew at least one complication of the procedure and
12(15%) knew an option or complication of anaesthesia. Forty-five (56.25%) of the consent forms were properly filled while other forms had one error or another.
Conclusion: Well structured and standardized method of obtaining informed consent from surgical patients should be adopted. While educating patients, the various alternatives to the procedure and possible complications should be carefully explained to the patients who should be carried along in decision making.
