Combined Use of Online Tutorials and Hands-On Group Exercises in Bibliographic Instruction for Pharmacy Students

This study describes the new blended learning methodology implemented in a Drug Literature Evaluation course for pharmacy students that involves combined use of online tutorials and in-class group exercises. Assignment grades earned by 909 students enrolled in the course before and after the new methods were implemented (2008–2010) were studied to measure student performance. Course evaluations were analyzed in order to ascertain students’ perceptions. The hybrid approach used to deliver the course content allowed students to perform at the same level as traditional didactic teaching. Students’ evaluations reported a positive educational experience and favorable perceptions of the new course design.     

Fostering theory of mind development. Short- and medium-term effects of training false belief understanding / Favorecer el desarrollo de la teoría de la mente. Efectos a corto y medio plazo de un entrenamiento en comprensión de la falsa creencia

Abstract

This study examines the temporal effect of different trainings designed to favour the development of false belief understanding. A sample of 78 pre-school children aged between three years, five months and three years, 11 months was divided into three training conditions. After three training sessions, they were immediately evaluated in post-test 1 and again a month and a half later in post-test 2. The results showed that the efficiency of the training conditions depended both on the type of linguistic communication and on the use of deceptive objects. Also, the effect of the training was maintained for at least a month and a half after post-test 1 and it was transferred from the trained task to other false belief tasks. The results are commented according to the possibility of using language-based trainings to foster children’s theory of mind understanding in educational contexts.     

Filipino Arts Among Elders in Institutionalized Care Settings

The use of traditional art in recreational therapies is unexplored. This paper, thus, attempts to surface the unique power of traditional Filipino arts (TFA) as synergizing lens in capturing the individual and the collective experiences of a select group of Filipino elderly in an institutionalized care setting relative to their feelings of depression and self-esteem. Three Filipino elderly housed in an institutionalized care setting were chosen for this phenomenological study, a robotfoto and a series of semistructured interviews constitute the main data gathering tool. Field texts were subjected to phenomenological reduction via the repertory grid analysis. Emerged themes were subjected to a series of member checking procedures to ensure the trustworthiness of the reported data. Depression and self-esteem were interpreted via two emerged themes. The themes were Me, Myself, and Melancholy and Will Not Let My Worth Wither. Through recreational therapies in the form of traditional Filipino arts, participants found novel psychological crutches that overcame the challenges of depression and give them hope toward more positive views of themselves and life.     

Upper Secondary Students’ Understanding of the Use of Multiple Models in Biology Textbooks—The Importance of Conceptual Variation and Incommensurability

In this study we investigate students’ ability to discern conceptual variation and the use of multiple models in genetics when reading content-specific excerpts from biology textbooks. Using the history and philosophy of science as our reference, we were able to develop a research instrument allowing students themselves to investigate the occurrence of multiple models and conceptual variation in Swedish upper secondary textbooks. Two excerpts using different models of gene function were selected from authentic textbooks. Students were given the same questionnaire-instrument after reading the two texts, and the results were compared. In this way the students themselves made a classification of the texts which could then be compared with the researchers’ classification of the texts. Forty-one upper secondary students aged 18–19 participated in the study. Nine of the students also participated in semi-structured interviews. Students recognized the existence of multiple models in a general way, but had difficulty discerning the different models and the conceptual variation that occurs between them in the texts. Further they did not recognize the occurrence of incommensurability between multiple models. Students had difficulty in transforming their general knowledge of multiple models into an understanding of content specific models of gene function in the textbooks. These findings may have implications for students’ understanding of conceptual knowledge because research has established textbooks as one of the most influential aspects in the planning and execution of biology lessons, and teachers commonly assign reading passages to their students without further explanation.

Reliability and validity of Yo-Yo tests in 9- to 16-year-old football players and matched non-sports active schoolboys

The purpose of this study was to examine the test–retest reliability and construct validity of three age-adapted Yo-Yo intermittent tests in football players aged 9–16 years (n?=?70) and in age-matched non-sports active boys (n?=?72). Within 7 days, each participant performed two repetitions of an age-related intensity-adapted Yo-Yo intermittent test, i.e. the Yo-Yo intermittent recovery level 1 children's test for 9- to 11-year-olds; the Yo-Yo intermittent endurance level 1 for 12- to 13-year-olds and the Yo-Yo intermittent endurance level 2 test for 14- to 16-year-olds. Peak heart rate (HR_peak) was determined for all tests. The distance covered in the tests was 57% (1098?±?680 vs. 700?±?272?m), 119% (2325?±?778 vs. 1062?±?285?m) and 238% (1743?±?460 vs. 515?±?113?m) higher (p?≤?.016), respectively for football-trained than for non-sports active boys aged 9–11, 12–13 and 14–16 years. The typical errors of measurement for Yo-Yo distance, expressed as a percentage of the coefficient of variation (confidence interval), were 11.1% (9.0–14.7%), 10.1% (8.1–13.7%) and 8.5% (6.7–11.7%) for football players aged 9–11, 12–13 and 14–16 years, respectively, with corresponding values of 9.3% (7.4–12.8%), 10.2% (8.1–14.0%) and 8.5% (6.8–11.3%) for non-sports active boys. Intraclass correlation coefficient values for test–retest were excellent in both groups (range: 0.844–0.981). Relative HR_peak did not differ significantly between the groups in test and retest. In conclusion, Yo-Yo intermittent test performances and HR_peak are reliable for 9- to 16-year-old footballers and non-sports active boys. Additionally, performances of the three Yo-Yo tests were seemingly better for football-trained than for non-sports active boys, providing evidence of construct validity.     

Student–Mentor Relationships and Students' College Attitudes

Many college and SAT preparation programs are designed to improve the postsecondary success of traditionally marginalized students. In addition to academic preparation, students' social and emotional preparation is important for the transition from high school to college. Mentors can serve as role models and supports to aid students in this development. Using student survey data and hierarchical linear modeling, this study examines the influences of student–mentor relationships within an SAT program setting on students' college attitudes. Results indicate that these relationships can positively influence students' college attitudes, particularly for students who have lower baseline SAT scores. Recommendations for future research and practice are provided.     

Definition of historical models of gene function and their relation to students’ understanding of genetics

Models are often used when teaching science. In this paper historical models and students’ ideas about genetics are compared. The historical development of the scientific idea of the gene and its function is described and categorized into five historical models of gene function. Differences and similarities between these historical models are made explicit. Internal and external consistency problems between the models are identified and discussed. From the consistency analysis seven epistemological features are identified. The features vary in such ways between the historical models that it is claimed that learning difficulties might be the consequence if these features are not explicitly addressed when teaching genetics. Students’ understanding of genetics, as described in science education literature, is then examined. The comparison shows extensive parallelism between students’ alternative understanding of genetics and the epistemological features, i.e., the claim is strengthened. It is also argued that, when teaching gene function, the outlined historical models could be useful in a combined nature of science and history of science approach. Our findings also raise the question what to teach in relation to preferred learning outcomes in genetics.
