ResumenEn este artículo se reporta una investigación en la cual se intenta averiguar si los estudiantes pueden adquirir habilidades necesarias para realizar factorizaciones algebraicas, utilizando software matemático. Para contestar la interrogante de la investigación, se aplicaron actividades a estudiantes de nivel secundaria y bachillerato, donde debían calcular factorizaciones algebraicas con ayuda del software GeoGebra, posteriormente se les pedía que buscaran patrones en los resultados que arrojaba el software para poder generar una factorización general. Después de analizar los resultados de la experimentación se encontró́ que los estudiantes son capaces de producir factorizaciones algebraicas generales, aunque presentan ciertas dificultades. Este trabajo cierra haciendo una discusión de las implicaciones que pueden tener los resultados encontrados.AbstractThis paper describes a research study focused on finding out if mathematics students can acquire skills necessary to perform algebraic factorizations by using mathematical software. To answer the research question, a group of lower secondary school students and high school students were involved in mathematical activities where there should calculate algebraic factorizations using the software GeoGebra, then they were asked to look for patterns in the results generated by the software in order to produce a general factorization. After analyzing the results of the experimentation, it was found that students are able to produce general algebraic factorizations, but some of them have some difficulties in doing so. This work is closed by a discussion of the implications of the research results.

Shame And Guilt

Abstract In the processual approach to identity, the role of the interaction between subjective and contextual factors in the process of its development is emphasized. Based on the model of Luyckx et al. (2008) relationships between identity and educational context, as well as the tendency to experience shame and guilt were analyzed.. 821 people aged from 14-25 and belonging to six educational groups: (1) lower secondary school, (2) basic vocational school, (3) technical upper secondary school, (4) general upper secondary school, (5) post-secondary school (medical rescue, massage therapy, cosmetology, occupational therapy) and (6) university, took part in the research. Two questionnaires were used: The Dimensions of Identity Development Scale (DIDS), to allow the measurement of the five dimensions of identity postulated by Luyckx et al (2008) and The Personal Feelings Questionnaire-2 (PFQ-2, Harder, Zalma, 1990) to measure of the shame and guilt proneness. The results show that general upper secondary school students in terms of the dimensions of identity are closer to lower secondary school students rather than to their peers from technical and vocational schools. Among general upper secondary school students not only was a higher intensity of an identity crisis observed, but also a strong tendency to experience shame and guilt. Among lower secondary school students and general upper secondary school students, people with diffusion and moratorium as identity statuses prevailed, while in the remaining groups the achievement and foreclosure identity were observed more frequently. A general relationship was also observed, namely, a greater tendency to experience shame was associated with a higher intensity of an identity crisis.

School Start Times

Most teenagers are chronically sleep deprived. One strategy proposed to lengthen adolescent sleep is to delay secondary school start times. This would allow students to wake up later without shifting their bedtime, which is biologically determined by the circadian clock, resulting in a net increase in sleep. So far, there is no objective quantitative data showing that a single intervention such as delaying the school start time significantly increases daily sleep. The Seattle School District delayed the secondary school start time by nearly an hour. We carried out a pre-/post-research study and show that there was an increase in the daily median sleep duration of 34 min, associated with a 4.5% increase in the median grades of the students and an improvement in attendance.

The Impact

Science education in Rwandan schools still faces a number of challenges including the lack or shortage of equipment available for science experiments. This paper describes research conducted to assess the impact of using improvised versus conventional laboratory equipment in experiments. Eighty-five lower secondary school students were assessed using a semi-experimental post-test design on thermal expansion of bodies. Data analysis using a t-test produced a t-Stat of 2.74 over a t-Critical of 1.98 indicating a statistical significance between the two experimental groups in favour of the group using improvised equipment. As a result, it is recommended that improvised equipment be used in those instances in which there is a lack or shortage of conventional equipment since students’ achievement was similar regardless of the type of equipment used.

The Individual

The paper presents the results of the study on participative mapping of landscape values and conflicts and a subsequent interpretation of the indicated localities from respondents’ point of view. The study focused on younger groups of landscape users—lower-secondary-school students (aged 11–15) and university students (aged 20–25)—in comparison with experts’ points of view. The research presumed that the perception of landscape values and issues are determined by age, level of education and by experience in the field. The study was conducted in the southeastern area of the Czech Republic (49° N, 16° E) via online data collection. Based on the obtained records, we conclude that, in terms of the typology of the valuable and problematic locations, the individual groups of respondents did not differ significantly and the selection of location types was similar across all groups. Lower-secondary-school students rather identified cultural values associated with everyday activities, and the descriptions contained emotional overtones. University students preferred natural values associated with formal values based on general consensus or conflicts associated with society-wide impacts. The experts base served as the benchmark for other groups.

And Gender

The study examined the influence of environment and gender on career choice among secondary school students in Kaura Local Government of Kaduna State. A descriptive research design was used and 18 secondary schools were clustered into three chiefdoms to draw a sample of 6 secondary schools using purposive sampling technique. Also, a sample of 422 students from a population of 3558 students from the three Chiefdoms was drawn using cluster sampling technique. The study developed and used a questionnaire tagged 'Environment, Gender and Career Choice Questionnaire (EGCCQ)' with correlation coefficient of 0.78. The students' career choice was based on the adoption of Career Interest Survey (CIS) and Vocational Interest Inventory (VII) developed by Bakare (1977). Descriptive statistics of simple percentage was used for the research question generated, while inferential statistics of multiple regression analysis was employed to analyse the null hypotheses developed for the study and tested at 0.05 level of significance. The findings revealed that students had preferences for career choice based on gender and environment. There was a significant composite influence of environment and gender on career choice among secondary school students in Kaura Local Government of Kaduna State, with the influence of environment being relatively than that of gender. It is therefore recommended among others that students should be well counselled in the choice of career process by professional counsellors and they should take into consideration the immediate environment of the students, their gender, interest, ability, skills and personality.
