Abstract On the topic of work and energy, students learned the concepts of work and energy, the relationship between work and energy changes, the law of conservation energy, power, and its application in daily-life. This research aimed to identify and evaluate the achievement of physics problem-solving skills of senior high school students on work and energy topics in distance learning during the Covid-19 pandemic. The quantitative method used was preexperiment with a one-shot case study design. The subjects were determined using the cluster sampling technique. The sample was 246 students of tenth-grade from three schools, namely in the city, middle, and suburb location in Tuban East Java Indonesia. The research results were analyzed by using descriptive quantitative. This research instrument used essay questions and teacher questionnaires. The Kruskal Wallis test showed that the mean of three schools differed significantly by 0.002<0.05. The overall students’ physics problem-solving skills on the topic of work and energy are classified as moderate. The fact of these findings suggests that students still have difficulty in useful description, physics approach, specific application of physics, mathematical procedures, and logical progression and consistent reasons. It is necessary to develop teaching materials that can train physics problem-solving skills.

A modification of the Paired-Stimuli Parent Program (Florance, 1977) was adapted for the treatment of articulatory errors of visually handicapped children. Blind high school students served as clinical aides. A discussion of treatment methodology, and the results of administrating the program to 32 children, including a two-year follow-up evaluation to measure permanence of behavior change, is presented.

Summary: This article describes a triarchic analysis of an aptitude-treatment interaction in a college-level introductory-psychology course given to selected high-school students. Of the 326 total participants, 199 were selected to be high in analytical, creative, or practical abilities, or in all three abilities, or in none of the three abilities. The selected students were placed in a course that either well matched or did not match their pattern of analytical, creative, and practical abilities. All students were assessed for memory, analytical, creative, and practical achievement. The data showed an aptitude-treatment interaction between students' varied ability patterns and the match or mismatch of these abilities to the different instructional groups.

This study examined how social opportunity structure influences identity exploration and commitment of Albanian high school students. A total of 258 students completed a questionnaire that gauged their identity exploration and commitment in three domains: education, occupation, and family. ANOVA results indicated that, overall, students scored highest in exploration in the domain of education and in commitment in the domain of family. Students' exploration and commitment were linked to gender. Albanian female students scored higher than male students in exploration and commitment regarding education and family. Perceived work opportunities in Albania or abroad also significantly moderated participants' exploration in the domain of education and were associated with commitment in education and occupation. As one of the first studies to explore Albanian youth's identity development in relation to social opportunity structure, findings are discussed in light of furthering the field of Albanian adolescent and youth development.

Abstract. This study investigated the effects of politicians’ nonparticipatory and participatory Facebook posts on young people’s political efficacy – a key determinant of political participation. We employed an experimental design, using a sample of N = 125 high school students (15–20 years). Participants either saw a Facebook profile with no posts (control condition), nonparticipatory posts, or participatory posts. While nonparticipatory posts did not affect participants’ political efficacy, participatory posts exerted distinct effects. For those high in trait evaluations of the politician presented in the stimulus material or low in political cynicism, we found significant positive effects on external and collective efficacy. By contrast, for those low in trait evaluations or high in cynicism, we found significant negative effects on external and collective efficacy. We did not find any effects on internal efficacy. The importance of content-specific factors and individual predispositions in assessing the influence of social media use on participation is discussed.
