This study contributes to a growing literature that investigates vocational students’ conceptual understanding of electricity by proposing a multidimensional and pragmatic approach to conceptual change. Conceptual change model-based activities were designed in a six-stage conceptual change model and were incorporated into a four-week course. The effectiveness of these activities was measured in terms of changing these students’ misconceptions about simple electric circuits towards scientifically accepted ideas in terms of their revolutionary versus evolutionary nature and the extent of transfer of learning. Transformative mixed methods research design was used consisting mainly of a one-group pre-test post-test design with DIRECT Test 1.2 as a research instrument. Paired samples t-test analysis for 15 students’ test scores indicated that there was a statistically significant difference between students’ pre- and post-test scores. The results of the frequency analysis in both pre- and post-tests show a significant percentage drop in the number of students having the identified misconceptions. The majority of students during post pre-test interviews justified their answers incorrectly, but more than 80% answered correctly in the post post-test interview. Key words: conceptual change, conceptual change model, electric circuits, misconceptions, vocational education.

Challenges in the learning photosynthesis topic may arise from misconceptions. This study investigated Grade 10 learners’ achievements in photosynthesis using the Conceptual Change Model (CCM) to minimize misconceptions and to develop understanding of photosynthesis in rural high schools in South Africa. A quasi-experimental design was used with a sample of 78 Grade 10 learners: 39 Experimental Group (EG) and 39, Control Group (CG). Achievement test, learning materials and a questionnaire were used to collect data. Data were analysed using descriptive statistics, t-test, Analysis of covariance (ANCOVA) and Pearson correlation. Results from post-tests show that EG taught using the CCM exhibited higher achievements than the CG taught using traditional approach. ANCOVA show that there were significant differences in performance between pre- and post-test of the EG. Performance and attitudes correlation was (r = 0.89) for EG and (r = 0.33) for CG, suggesting that CCM positively influenced learners’ attitudes towards Life Sciences. Key words: achievement, attitude, conceptual change, misconceptions.

Learning physics for senior high school (SMA) students is often coloured by misconceptions that hinder students in achieving deep understanding. So a relevant learning model is needed. This study aims to examine the effect of conceptual change model (CCM) compared with direct instruction model (DIM) on the students’ conceptual understanding and character in the subject area of motion and force. This quasi-experimental research using a non-equivalence pre-test post-test control groups design. The population is 20 classes (738 students) of grade X consisted of 8 classes (272 students) of SMA 1 Amlapura, 8 classes (256 students) of SMA 2 Amlapura, and 6 classes (210 students) of SMA 1 Manggis in Karangasem regency in Bali. The random assignment technique is used to assign 6 classes (202 students, or 26.5% of the population). In each school there are set 2 classes each as a CCM group and DIM groups. The data of students’ conceptual understanding is collected by tests, while the characters by questionnaires. To analyse the data a one way MANCOVA statistics was used. The result of the analysis showed that there was a significant difference of effect between CCM group and DIM group on the students’ conceptual understanding and character. The effect of the CCM group is higher than the DIM group on the students’ conceptual understanding and character in learning subject area of motion and force.

This study integrated cooperative learning methods in classroom instruction to investigate the effects on achievement and conceptual change in matter concepts involving 70 fifth grade students after 10 weeks of instruction. Data obtained from the administration of two achievement tests indicated that there were significant differences between the pre-test and post-test mean scores on the Matter Unit Test as well as on the Matter Diagnostic Test. Since the notion of status is fundamental to the Conceptual Change Model (Posner, Hewson, Strike & Gertzog, 1982) this study also investigated the students' ability to determine the status of their own conceptions. Analysis of the students' use of written descriptors provided varied evidence of their ability to use technical language (intelligible, plausible, or fruitful) and effectively determine the status of their own conceptions.

The purpose of this study was to determine whether the concrete-pictorial-abstract (CPA) approach developed based on the Collaborative Lesson Research (CLR) cycles can positively impact Year Four pupils’ proficiency in perimeter. Counterbalanced design was used with pre- and post-test in every CLR cycle. The participants involved were three groups of pupils totaling 115 pupils and a group of three teachers. The sampling used was cluster random sampling. A paired-samples t test was used to determine whether there is a significant difference between the pre- and post-test for each CLR cycle while a one-way ANOVA test was used to analyze if there is an increase in proficiency from the first, second and third CLR cycles. The results indicated that there was an increase in the mean post-test scores compared to the mean of pre-test scores and the mean difference between the first, second and third CLR cycles. In conclusion, the CLR cycle carried out helped teachers in developing better teaching plans based on the CPA approach as well as enhancing pupils’ proficiency in the perimeter.

This study aims to investigate whether the use of six selected short stories throughout the duration of a 14-week course could enhance students’ reading comprehension achievement at the end of the semester. Out of the six short stories read, three were chosen as in-class assignments known as ‘Personal Reading Logs’ (hereafter, PRLs). One group of semester two Diploma students taking a reading skills course was selected through a convenience sampling method. A pre-test was conducted by having the students answer a past semester reading quiz of which the results would then be compared to their post-test (final reading exam) results. A paired samples t-test revealed no significant difference in the reading scores of the pre-test and the post-test, t (17) = -.265, p > .05. Since the p-value was bigger than 0.05, this indicated that the mean reading score of the post-test (M = 50.556) was not significantly higher than the mean reading score of the pre-test (M = 49.722). Therefore, the null hypothesis which stated that there was no difference in the mean score of the pre-test and post-test was retained. Overall, the result refuted the findings of other studies promoting the effectiveness of using short stories to enhance L2 reading comprehension achievement.

Abstract Objective Lack of palliative care knowledge among caregivers may pose an access barrier for cognitively impaired older adults, who may benefit from the specialized care. Therefore, this study aims to examine the effectiveness of an educational intervention in improving palliative care knowledge among informal caregivers of cognitively impaired older adults. Method Using a one-group, pre- and post-test intervention design, this study implemented an individual, face-to-face educational intervention with an informational brochure for 43 informal caregivers of chronically or seriously ill older adults (50+) with cognitive impairment, recruited from communities in West Alabama. Their level of knowledge about palliative care was assessed by the Palliative Care Knowledge Scale (PaCKS). The pre- and post-test scores were compared by the Wilcoxon signed-ranks test, and the racial subgroup (Whites vs. Blacks) comparison was made by the Mann–Whitney U test. Results There was a statistically significant difference between the pre- and post-test scores (z = 5.38, p < 0.001), indicating a statistically significant effect of the educational intervention in improving palliative care knowledge among participants. There was a significant difference (U = 143, p < 0.05) between Whites and Blacks in the pre-test, which, however, disappeared in the post-test (U = 173.50, p > 0.05), suggesting that the amount of increased PaCKS scores were significantly greater for Blacks (Mdn = 9.50) than for Whites (Mdn = 4.00, U = 130.50, p < 0.05). Significance of results This study demonstrated that a one-time educational intervention can improve the level of palliative care knowledge among informal caregivers of chronically or seriously ill older adults with cognitive impairment, particularly among Black caregivers. Therefore, further educational efforts can be made to promote palliative care knowledge and reduce racial disparities in palliative care knowledge and its use.

AbstractPresent study was aimed at investigating the role of Physical, Environmental, Task, Timing, Learning, Emotion and Perspective (PETTLEP) Imagery technique in the improvement of skill precision level of hockey drag flickers. For this purpose, both male (83) and female (38) hockey drag flickers (n=121) of age ranged between 17 and 27 years were selected from different hockey teams belonging to clubs, colleges, universities, departments, regional and national academies of Pakistan. Participants were made to undergo a Pretest-Intervention-Posttest research design consisted of 20 drag flicks and filling of SIAQ questionnaire. Drag Flick Precision Measurement Test (DFPMT) along with Sports Imagery Ability Questionnaire (SIAQ) were used to measure their skill precision levels and their imagery ability. The participants were classified into three categories as per their skill precision levels (Point-based), ranging from 48 Novice (upto12 points), 42 Intermediate (13–18 points) and 31 Elite (19 points and above), and were randomly assigned to one of four intervention groups; Physical Practice (PP), PETTLEP Imagery Practice (IP), Physical Practice+PETTLEP Imagery Practice Combination (CP), and No Practice (NP) Control group. Each group performed their respective tasks for 10 weeks through specially designed physical training programs aided by Imagery scripts. Paired sample t test analysis showed that all groups improved significantly (p<0.05) from pre- to post-test, and the CP group improved more with average improvement value of 8.32 for DFPMT and 5.39 for SIAQ (p<0.05) than the IP, PP and NP groups. However, there was no significant difference found between the PP (Sig. 0.73) and NP (Sig. 0.44) groups in SIAQ. Result extend prior research findings and suggests that PETTLEP Imagery practice used in combination with Physical practice has substantial impact on improving performance of complex motor skills, Present findings showed that PETTLEP imagery model was found to improve player’s precision skill levels, especially when it was combined with physical practice. However, further studies in this connection are needed.

We explored the contribution and effectiveness of state and non-state institutions in rural development efforts in highlands (Khyber Pakhtunkhwa [KPK] province) of Pakistan. This study employed mixed-methods research design and data were collected from 300 household heads, randomly selected from six villages from two purposively selected districts Mansehra and Nowshehra. Findings showed people in KPK were deprived of due to conflicts, conspiracies and terrorism, poor governance, small landholdings and subsistence farming followed by sluggish marketing system, insufficient education and training for people, and inadequate employment opportunities. Regarding contribution, non-state institutions had more contribution as compared to state institutions. T-test analysis showed that the non-state institutions had an effective provision of agricultural extension and forestry advisory services, education, health services in remote areas, skill development, and provision of microcredit schemes. The results of F-test statistics showed highly significant difference among the perceived effectiveness of rural development activities of different types of non-state actors (localite, cosmopolite, and religious/faith-based) working in the research area. This study recommends state-owned rural development departments revisit their working mechanism and develop synergistic working relationship with the non-state institutions in discharging rural development efforts.
