Subjektívne vnímané riziká užívania psychedelík

Introduction. With growing interest in hallucinogens, majority of psychedelic research focus mostly on the therapeutic potential and benefits. The objective of this paper is to explore how users of psychedelics verbalize their experience and perceived risks of using such substances. Methods. The authors used a questionnaire with open-ended and multiple-choice items. The sample included persons with at least one phenomenological experience with psychedelics (N = 422, age M=27.78; SD=7.84; SE=0.38; 35.1% women). Qualitative data were analyzed using concepts of The Grounded Theory using the Atlas.ti suite. Results. The target group uses terms taken from the English language (“bad trip”, “set and setting”, “sitter”, or the grammatically localized version of the word „psychedelic“), with shared and well-understood semantic meaning within the community. The central domain “inappropriate set and setting” and its inadequate preparation is linked to the negative experience of “bad trip” which can lead to difficult “integration of experience” or even “psychotic disorders”. Users of psychedelics report various harm reduction strategies which are consistent with relevant literature. Conclusion. This study illustrates that Slovak users of psychedelics seem to understand and use the established terminology of international discourse related to these substances. At the same time, the authors suggest that users seem to use various relevant strategies to lower risks associated with the use of psychedelics.

the effect of Needham’s Constructive Model on the achievement of the 2nd year intermediate students in Mathematics and their attitudes towards it

The study aims to identify the effect of Needham’s Constructive Model on the achievement of the 2nd year intermediate students in Mathematics and their attitudes towards it. The researchers used the experimental design of partial control for the control and experimental groups. The study sample is 68 students, where the experimental group is 34 students, and the control group is (34) students. The researchers prepared two scales as achievement test, which include (30) multiple choice items. Items psychometric properties and statistical analysis have been got, and a scale of attitudes towards mathematics that includes (30) items with three alternatives. Items reliability, validity, discrimination coefficients are got. The two groups were rewarded in the variables of age and previous achievement in mathematics, IQ test and attitudes scale. After applying the experiment and the two study tools on the study sample, the results showed that there were statistically significant differences at the level (0.05) in favour of the experimental group in achievement and attitude towards mathematics. Key words: Needham’s model attitudes toword mathematics

Student Concept Mastery on Coloid Material Through Radec Learning

Mastery of concepts is still the main standard of learning success in Indonesia. This study aims to analyze students' conceptual mastery of colloidal material through the RADEC (Read, Answer, Discuss, Explain, and Create) learning model. The research method used is the Pre-Experiment method with the research design of One Group Pretest-Posttest Design. The number of subjects in this study were 18 students. Data were collected using 25 multiple choice items used for pretest and posttest. Data were analyzed through normality test, t test and N-gain using SPSS version 21 for windows. The results of the Paired Sample T-Test showed that there was a significant difference between the pretest score (39.7) and posttest score (74.4) (p<0.05) with the N-gain value obtained was 0.56. This means that there is an increase in the medium category in students' concept mastery through RADEC learning.

Entwicklung und psychometrische Evaluation eines herstellerunabhängigen Wissenstests zum kontinuierlichen Glukosemonitoring in Echtzeit für insulinbehandelte Menschen mit Diabetes

Zusammenfassung Hintergrund Um vom kontinuierlichen Glukosemonitoring in Echtzeit (rtCGM) optimal zu profitieren, benötigen die Anwender praktische Fähigkeiten und ausreichende Kenntnisse, um die Glukosewerte zu analysieren und ihre Insulintherapie geeignet anzupassen. Zur Erfassung des Wissens der Anwender über rtCGM wurde ein psychometrischer Fragebogen entwickelt und dessen Gütekriterien wurden überprüft. Methode Experten zur Nutzung von rtCGM definierten in einem Delphi-Verfahren zentrale Wissensinhalte und entwickelten einen 40 Multiple-Choice-Items umfassenden Wissenstest. Zur teststatistischen Überprüfung des Fragebogens beantworteten Personen mit insulinbehandeltem Diabetes und Mitglieder von Diabetesteams den Wissenstest. Ergebnisse Die 122 Mitglieder der Diabetesteams (Alter 46 (11) Jahre; Mittelwert (SD)) und auch die 111 Personen mit insulinbehandeltem Diabetes (Alter 42 (14) Jahre, Diabetesdauer 20 (14) Jahre, Therapie mit einer Insulinpumpe 64 %, Nutzung eines CGM-Systems 38 %, HbA1c-Wert 8,0 % [95 %-KI 7,7–8,3]; 64 mmol/mol [KI 60–67]) hatten einen unterschiedlichen Erfahrungsstand im Umgang mit rtCGM-Systemen. Die interne Konsistenz des Fragebogens (Cronbach’s alpha) betrug für die gesamte Stichprobe 0,92, für die Personen mit Diabetes 0,94 und für die Mitglieder der Diabetesteams 0,84. Der Schwierigkeitsgrad der Items lag zwischen 0,12 und 0,88 bei den Personen mit Diabetes und zwischen 0,27 und 0,97 bei den Teammitgliedern. Im Durchschnitt beantworteten Personen mit Diabetes 24,1 (9,9) Items richtig, Mitglieder von Diabetesteams 29,2 (5,2) (p < 0,001); Personen mit Diabetes und vorheriger rtCGM-Erfahrung unterschieden sich im Wissen von den Personen ohne Vorerfahrung (29,2 (6,2) vs. 21,0 (10,4) (p = 0,001)). Die Güte der Glukosekontrolle (gemessen als HbA1c-Wert) der Personen mit Diabetes war signifikant mit dem Summenscore des Wissenstests assoziiert (rho = –0,48, p < 0,001). Schlussfolgerung Der Wissenstest „rtCGM-Profi-Check“ weist eine sehr gute interne Konsistenz, Trennschärfe und inhaltliche Validität auf. Er eignet sich zur objektiven, reliablen und validen Erfassung des notwendigen Wissens, um rtCGM-Systeme erfolgreich einzusetzen. Der Fragebogen wurde herstellerunabhängig konzipiert und kann genutzt werden, um den Lernbedarf von Personen mit Diabetes und deren Lernerfolg durch eine rtCGM-Schulung zu erfassen.

A Misconception Investigation of Ninth Grade Students about Magnetism

This study aimed to identify the ninth grade students' misconceptions related to magnetism topic. For this purpose, an instrument consisting of two phases (two-tier) with fourteen multiple choice items on magnetism concepts was developed by the researcher. The diagnostic test was given to thirty-two ninth grade students. The findings indicated that 9th grade students experience misconceptions about the concept of magnetism including how to make and determine artificial magnetic poles, Lorentz force and GGL Induction. The results of this study can be used by teachers and researchers to choose substantial learning strategies for teaching magnetism material.
