Teaching Problem

Besides improving students' understanding of scientific concepts, chemistry teaching should also improve students' ability of applying concepts to solve problems. The research aims to explore the effects of modeling teaching on students’ proficiency in solving galvanic cell problems. This research used a quasi-experimental design, and the independent variable of the research was the teaching method. Forty-five students in the experimental class received modeling teaching, and 48 students in the control class received lecture-style teaching. The dependent variable was the performance level of the student's ability to solve the problem of the galvanic cell, which was evaluated using the galvanic cell proficiency assessment tool. The research results show that the students in the experimental class were significantly more proficient in solving galvanic cell problems than those in the control class. The results of unstructured interviews assisted in illustrating the role of modeling teaching in improving the proficiency of students in solving galvanic cell problems, and students in the experimental class had positive views on modeling teaching.

Collaborative Concept Mapping

In Kenya, the fundamental challenge facing chemistry teaching in secondary schools is how to enhance students’ conceptual understanding; a need for meaningful learning. The challenge has led to students’ underachievement in chemistry in national examinations. Research findings indicate that teaching method is a crucial factor affecting students’ learning and achievement. The present study investigated the effect of Collaborative Concept Mapping (CCM) teaching strategy on students’ achievement in Chemistry. Solomon Four Group quasi-experimental research design was used in the study. Four co-educational secondary schools were randomly selected for the study from secondary schools in Bomet District, Kenya. Students in experimental groups were taught using CCM teaching strategy for 8 weeks while the rest were taught using conventional teaching methods. Mole Concept Achievement Test (MCAT) was administered to determine students’ achievement on the topic of “mole concept”. Results of the study showed that CCM as a teaching strategy had no significant effect on the achievement among students of low and average academic abilities as well as those of higher academic abilities at 0.05 α significance level.

Competency Evaluation

Background:: Clinical competence of pharmacy students is better evaluated at their practice sites. compared to the classroom. A clinical pharmacy competency evaluation rubric like that of the American College of Clinical Pharmacy (ACCP)is an effective assessment tool for clinical skills and can be used to show item reliability. The preceptors should be trained on how to use the rubrics as many inherent factors could influence inter-rater reliability. Objective:: To evaluate inter-rater reliability among preceptors on evaluating clinical competence of pharmacy students, before and after a group discussion intervention. Methods:: In this quasi experimental study in a United Arab Emirates teaching hospital, Seven clinical pharmacy preceptors rated clinical pharmacy competencies of ten recent PharmD graduates referring to their portfolios and preceptorship. Clinical pharmacy competencies were adopted from ACCP and mildly modified to be relevant for the local settings. Results:: Inter-rater reliability (Cronbach's Alpha) among preceptors was reasonable being practitioners at a single site for 2-4 years. At domain level, inter-rater reliability ranged from 0.79 - 0.93 before intervention and 0.94 - 0.99 after intervention. No inter-rater reliability was observed in relation to certain competency elements ranging from 0.31 – 0.61 before intervention, but improved to 0.79 – 0.97 after intervention. Intra-class correlation coefficient improved among all individual preceptors being reliable with each other after group discussion though some had no reliability with each other before group discussion. Conclusion:: Group discussion among preceptors at the training site was found to be effective in improving inter-rater reliability on all elements of the clinical pharmacy competency evaluation. Removing a preceptor from analysis did not affect inter-rater reliability after group discussion.

The purpose of this study was to implement a comprehensive teaching program based on the principles of Teaching Games for Understanding (TGfU) model and questioning, and to assess its consequences for students’ satisfaction of basic psychological needs, motivation, perceptions of ability and intention to be physically active during Physical Education lessons in primary education. A quasi-experimental design was utilized. Participants were 111 students from two different groups of fifth and sixth graders, all enrolled in one primary school. Participants were divided into experimental and control group. Experimental group experienced a TGfU unit, according to small side games and the questioning. Control group experienced a small side games unit, without questioning. Within-group results showed that experimental group students reported significantly higher mean scores in all dependents variables of the study, in both genders. Results showed that control group only reported significantly higher mean scores in intention to be physically active variable, also in both genders. The results demonstrate the need to implement didactic units under comprehensive pedagogical approaches to improve motivation and the intention to develop healthy lifestyle habits in female and male students. More researches are needed to support this evidence.

Teaching Learning

Conventional methods employed to teach chemistry imply a lot of memorization and very little contextualization, i.e., they fail to connect chemistry concepts to students’ everyday lives, which causes them to lose motivation and interest in learning the subject. In order to change this scenario, new methods have been proposed for the teaching of chemistry, such as playful experimentation, to foster contextualization of content and integration with content from other subjects. This study has aimed to evaluate student learning of chemistry concepts by means of experimentation associated to forensic science. To this end, first, students’ previous knowledge of the content was assessed by means of a questionnaire prior to the intervention. Then, they were given a problem-situation, a fictitious crime, which they had to solve. The results indicate that the teaching method under investigation is an effective teaching-learning strategy capable of contextualizing and adapting chemistry concepts to students’ cultural background, since TV crime series have become hugely popular among teenagers.

Chemistry is one of the scientific disciplines considered difficult for students to understand its microscopic and macroscopic concepts. Students also claim that this discipline is tedious and complicated. They are unable to connect what is shown in the visual structure to the process and phenomenon. In the context of self-motivation among university students, there is a higher chance of expanding the stimulation of learning. This study aimed to improve self-confidence and the mastery of concepts of chemistry teaching students using problem-based learning. The quasi-experimental method was used with the design of the non-equivalent pre-test-post-test control group. The population included all students in the electrochemistry class at Lampung University in 2019. The purposeful sampling technique employed divided the sample into two groups. The first group was called Class A and was considered as the experimental class - using problem-based learning -. The second group, Class B, was recognized as the control class - using the conventional model in which the teacher applied the speech method in the delivery of materials during the class -. Class A's self-confidence and mastery of concepts have a higher nGain value than class B, and the result of the effect size is that class B has a more significant effect than class A. Based on the outcome, one can conclude that problem-based learning has a significant influence on improving self-confidence and mastery of concepts on the electrochemical theme.

Results from the development of a novel sensory and perceptual test to assess the level of altered visual size perception in people with schizophrenia are presented. Here we compare the performances in a visual sensory and perceptual test between a control group and an experimental group of people diagnosed with schizophrenia. We have been using paintings by Salvador Dalí and Rorschach plates to assess images size perception. In this transversal, ex-post-fact and quasi-experimental study we show differences between EG (Experimental Group) and CG (Control Group). Schizophrenics in-patients as compared to controls perceived sizes about 1.3 fold greater than healthy volunteers (p=0.006), thus showing that size perception is altered in schizophrenia. Together with previous results, this particular sensory test for size perception seems to be a useful assessment tool to evaluate the degree and severity of psychotic symptoms in prodromal schizophrenic states, and neuropsychiatric patients in general. It may help prevent acute crisis with proper, and most likely, lower dosages of medication.

The increase in the needs of the English language learners (ELLs) and their endless demands in terms of achievement and proficiency in all the educational systems all over the world urged teachers and educators to call for new teaching strategies that sound more adequate and appropriate in the classroom. The Sheltered Instruction Observation Protocol (SIOP) Model emerged as one of the worldwide prominent teaching methods that guarantee the ELLs success, especially when it has to do with the understanding of the content and language learning meanwhile. With its diverse culture and prominent engagement in terms of education, Morocco represents a fertile field for the implementation of the SIOP Model that has proven in different contexts its adequacy in helping ELLs achieve proficiency. This study is about a quasi-experimental research that is implemented in an urban school known for its diversification in terms of mother tongue, socio-economic status, gender, and background. Given these different circumstances of the learners, the findings reported after the adoption of the SIOP Model as a teaching approach showed that it is a reliable and adequate teaching method in terms of content and language proficiency. The use of wh-questions as key indicators to measure the learners’ capacity of understanding and responding correctly throughout the experiment phase showed the superiority of the ELLs in the SIOP classes in contrast to the learners in the mainstream classes. This superiority is embodied, especially in terms of the high scores obtained in providing correct answers in a short duration of time. <p> </p><p><strong> Article visualizations:</strong></p><p><img src="/-counters-/edu_01/0726/a.php" alt="Hit counter" /></p>

The Canadian Engineering Accreditation Board’s definition of professionalism, one of twelve graduate attributes, does not mention professional behaviour, but rather focuses on understanding the role of engineers in society. While difficult to define, challenging to teach, and even harder to assess, the engineering faculty at the University of Guelph felt professional behaviour was an important element of professionalism to consider in their curriculum.  This study investigates how professional behaviour might be taught and assessed. The researchers developed course material on professional behaviour for the winter 2019 offering of a third-year multidisciplinary design course (369 students), using Kelley et al.’s (2011) Professionalism Assessment Tool (PAT). Using a quasi-experimental design, the researchers assessed whether student professionalism improved based on their change in PAT scores over the semester using a Wilcoxon Signed-Rank test. They also analyzed a sample of student final reflections on professional behaviour. Student PAT scores increased significantly over the semester (n = 340, p<0.05), but the effect sizes observed, using Cohen’s d, were small (0.14 to 0.29). The student reflections (n = 53) suggest that improvements to their professionalism were a result of working in a team, experience gained from their project, and individual efforts made to behave professionally.  While infrequently discussed in the reflections, over half of the post-term survey responses revealed that students felt the lab activities helped improve their professional skills generally, and/or increased their awareness of these skills. The improved awareness aspect of student professionalism was an unexpected, but important outcome of the PAT-based course material and may have reinforced student ownership of their soft skill development.

This chapter presents the statistical analysis of the quasi-experimental study in which five types of written CF were examined. The results show that more explicit written CF types were more effective on facilitating L2 development. However, although participants are of different English proficiency, it was not found that proficiency level had an impact on the effect of written CF.
