This paper is prompted by and based on earlier research into developers' overconfidence as one of the main causes of spreadsheet errors. Similar to related research, the aim of the paper was to ascertain the existence of overconfidence, and then examine the possibility of its reduction by means of experimental treatment designed for the needs of the research. A quasi-experiment was conducted to this end, in which 62 students of the Faculty of Economics of the University of Novi Sad participated, divided into the experimental and control group. Participants of both groups developed domain free spreadsheets in two iterations each. After the first iterations, students in the experimental group were subjected to experimental treatment: they attended lectures on spreadsheet errors taxonomies supported by real-life examples, and about spreadsheet best practices in the area of spreadsheet error prevention. Results showed that spreadsheet developers who were informed about spreadsheet error taxonomies and spreadsheet best practices create more accurate spreadsheets and are less self-confident in terms of accuracy of their spreadsheets.

The purpose of the research project is to investigate how far the academic writing skills of Binus University students can be developed through two conflicting CLT methods: standard and principled. The research project is expected to result in computer-animated format which can be used as one of the main tools in teaching and learning grammar at Binus University. The research project uses the qualitative approach, and thus uses verbal data. The research project involves two subject groups (experimental and control). The experimental group will receive the treatment of grammar learning by using the Principled CLT approach, while the control group receives the standard CLT approach. Survey is then conducted to the two groups so as to find out their comments on the two teaching methods. From the results of the questionnaires, it is found that Principled CLT method is favored for its knowledge and accuracy factors, while the Standard CLT is preferred for its fun and independence factors.

Rubric has been associated with the term assessment used for grading and/or scoring. However, it might observe less, but it is also designed as students ‘learning tool. This study was conducted to provide empirical facts on its effectiveness as a learning tool in teaching Applications of Derivatives in Basic Calculus. It used the quasi-experimental design called the pretest posttest design. The participants were the 96 students from two classes of Grade 11 STEM students at the University of Mindanao. The instruments used were the adapted and improved rubric designed from two different research, a 25-item teacher-made problem-solving test questionnaire that was used in both pretest and posttest to measure the performance of the experimental and control group. The test questionnaire and rubric were both validated by 3 experts in the field with a result of very good, and it has a good internal consistency. The data gathered were summarized, translated, and analyzed using the mean scores of pretest and posttest. Findings showed that both the experimental and control group showed improvement, however, the experimental group who used rubric as a learning tool showed more significant improvement than control group. Thus, using a rubric as a learning tool in teaching Applications of derivatives is effective in improving students’ academic achievement as it teaches students to develop their understanding of procedural knowledge.

This research aims at investigating the effect of blended learning on the achievement and motivation to learn English of German Jordanian University students. A pilot case study research strategy was used. Pilot case studies are effective research strategies for investigating educational issues in real life situations. They are used to refine research problems, variables, and also to refine the case study design before doing it in a larger-scale investigation. The study sample comprised 34 students who were selected purposefully and distributed into experimental and control groups. The experimental group studied English through a computerized program melded with the traditional method, whereas the control group was taught solely by the latter. The analysis of covariance (ANCOVA) revealed statistically significant differences in achievement between the two groups, indicating that the experimental group performed better than the control group. Significant differences were also found in the respective groups’ motivation to learn English.

AbstractBackgroundMilton Erickson was the first to introduce hypnosis as a form of therapy during the post-war period. Numerous studies have evaluated the effects of hypnosis on memory, focusing principally on post-hypnotic amnesia, post-hypnotic hypermnesia, faux memories and learning growth.The aim of the present study was to determine if hypnosis can influence visual-spatial memory by increasing its performance and learning; to do this, we chose to utilise the Corsi Test (backward and forward).MethodsThree hundred second-year students enrolled in the psychology faculty at the University of Catania were informed of the research and its modalities, and an e-mail was sent to inquire if they wanted to participate in the experiment.Seventy female students took part in the research; 10 were excluded because they presented a high risk of being influenced under hypnosis.The 60 subjects in the research sample were randomly divided into two groups: the Experimental Group and Control Group.The protocol prescribed administration of the Corsi Test at Time 0 (start) followed by a resting phase of 30 min. The hypnotic state was subsequently introduced, and the Corsi Test was administered again.ResultsThe results of the Corsi Test for the Experimental Group showed statistically significant results (p<0.0004 and p<0.0001), while the results obtained in the Control Group did not show any significance.ConclusionsThese results led us to believe that hypnosis has the capacity to induce a nervous plasticity that supports learning of visual-spatial memory.

This study was conducted at a university based in KwaZulu-Natal, South Africa. The purpose of the study was to determine if the explicit instruction of selected grammar aspect, modal auxiliary verbs, improved students’ ability to write English. The study was qualitative in nature and a case study design was adopted. The focus was in relation to a sample of 80 student teachers who were randomly selected in 2016 in the Faculty of Education. 40 participants were randomly assigned into experimental and control groups. For the experimental group, training lasted six weeks. Both groups were made to write similar essays and those essays were marked focusing on the students’ ability to use modal auxiliary verbs. The study’s findings revealed that the experimental group performed better than those in the control group in the use of modal auxiliary verbs. Based on the findings, the study recommended explicit grammar instruction in all the students’ level of study in order to overcome the challenges they have in writing English. Thus, time should be created to ascertain that adequate explicit grammar lessons are offered to all pre-service teachers at the university.

This study was intended as a contribution to the argument about possible suffering of animals used for demonstrative purposes during teaching at universities. Pharmacology lectures at the University of Veterinary and Pharmaceutical Sciences Brno, Czech Republic were selected for this experiment. The study focused on stress assessment using haematological and biochemical indices. Blood samples were drawn from 20 rabbits (Oryctolagus cuniculus f. domesticus L.) 10 days after arrival at the institute (before the first practical lesson), and then in the 7th and 12th weeks of the semester with practical lessons. The haematological and biochemical indices were compared between the experimental group (n = 10) used for practical demonstrations and the control group (n = 10) which was kept in its hutch. Practical lessons included manipulation with rabbits, health examination, topical or total application and observation of the drugs’ effects. All the acts were carried out by students. Significant changes were detected in some of haematological (erythrocytes, haemoglobin, haematocrit) and biochemical (glucose, total protein, enzymes aspartate aminotransferase and lactate dehydrogenase) variables compared to the control group. The values obtained from the last blood sampling indicate a possible habituation process in the experimental group between the 8th and 12th week. The results were compared between the experimental and control group and also with the results of other studies with different stressors. In conclusion, the stress the rabbits used for teaching purposes at universities are exposed to, is tolerable.

With the access of the millennials to the contents of the internet through their smartphones, a new educommunicative ecosystem emerges that favors communication through immediacy and interactivity. This research seeks to know the habitual and spontaneous use of millennial smartphone during an on-campus class at the university. Experimental research has been used, using neuroscientific techniques of electrodermia, to measure the attention of subjects and their emotions at the group level, as well as a complementary quantitative questionnaire. The experiment was carried out with 44 people distributed in the two groups with 22 subjects in each one (experimental group and control group), with ages between 20 and 21 years of age of both sexes (in a similar proportion). 45% said they use the smartphone in class to chat, 29% to enter social networks and 5% indicated the use of the smartphone to take photos. 21% said they never use the smartphone in class. Regarding the neuroscientific experiment there was an increase in attention in the session in which the use of smartphone was prohibited. The students declare that they have smartphone usage patterns in the classroom similar to those they have outside the classroom. There were no significant differences in the duration and average intensity of attention and emotion between the experimental group and the control group.
