Abstract Studying science through hands-on activities within the context of teaching and learning using local environments and resources has been recognized as a fundamental prerequisite of school curriculum in many developing countries, including Thailand. Accordingly, we are interested in implementing such a concept in designing science teaching and learning for middle school students that emphasizes student participation in the provision of materials and equipment for scientific activities. The purposes of this study are to design hands-on activities for eighth grade students on the topic of light reflection using low-cost materials, and then to examine the results after they are implemented. The experimental group consisted of 30 eighth grade students who were chosen at random in one room. The instruments used in the experiment were two types of achievement tests that were administered as pretests and posttests on the topics of light reflection on smooth and curved surfaces. The paired sample t-test was performed after the collection of data to determine students’ conceptual understanding. Our result displays a highly significant difference (p <.01) between the pretest score (39.7%) and posttest score (83.3%), indicating that students actively participated in hands-on activities and learned light reflection knowledge and skills through interaction and discussion with their classmates. We highlight the advantages of our study for science teachers in rural schools in ensuring students develop 21st Century Skills, which is an important part of STEM education.

Recount text is one of the texts in writing which must be taught and stated in Junior High School curriculum. Some students felt that reading text is boring because the students tend to be very lazy to read the text, so that they are not interested in English lessons. The researchers used group investigation technique as one of alternatives in teaching and learning to develop the material and make students more active and interested in class. The objective of this research is to find out whether teaching using group investigation technique is able to develop the students’ reading in recount text at the eighth grade students of SMP Negeri 17 Kota Serang. The methodology of this research was a quantitative research method by using true experimental design. The study was carried out into two classes, Class VIII E as experimental class, and Class VIII C as control class. The results of the study showed that group investigation was able to develop students’ reading comprehension in recount text. Mean of posttest score of the experimental class (67.31) was higher than the control class (64.18). Based on the statistical analysis using t-test analysis, it showed the value of tcount ≥ ttable = 49.12 ≥ 1.99. It means that (Ha) was accepted and the (H0) was rejected. It can be concluded that group investigation is able to develop students’ reading comprehension in recount text at eighth grade students of SMP Negeri 17 Kota Serang.

Background: Environmental provisions can boost students’ discretionary participation in physical activity (PA) during lunchtime at school. This study investigated the effectiveness of providing PA equipment as an environmental intervention on middle school students’ PA levels and stakeholders’ perceptions of the effectiveness of equipment provisions during school lunch recess. Methods: A baseline–intervention research design was used in this study with a first baseline phase followed by an intervention phase (ie, equipment provision phase). A total of 514 students at 2 middle schools (school 1 and school 2) in a rural area of the western United States were observed directly using the System for Observing Play and Leisure Activity in Youth instrument. Interviews were conducted with stakeholders. Paired-sample t tests and visual analysis were conducted to explore differences in PA levels by gender, and common comparison (with trustworthiness measures) was used with the interview data. Results: The overall percentage of moderate to vigorous PA levels was increased in both schools (ranging from 8.0% to 24.0%). In school 2, there was a significant difference in seventh- and eighth-grade students’ moderate to vigorous PA levels from the baseline. Three major themes were identified: (1) unmotivated, (2) unequipped, and (3) unquestionable changes (with students becoming more active). Conclusions: Environmental supports (access, equipment, and supervision) significantly and positively influenced middle school students’ lunchtime PA levels.

Class Scheduling

The objective of this study was to investigate whether the class scheduling of Nature and Biology classes in blocks results in better learning success for primary school students, and whether this depends on the average student success rate (i.e., student performance categories), age, or prior knowledge. For this study, we have assumed that block scheduling results in better success rates for older lower-performing primary-school students. The research included 773 fifth- to eighth-grade students from 14 Croatian primary schools. The students fell into two groups: one group attending 45-min Nature and Biology lessons twice a week (single-scheduled classes), and another group attending a 90-min lesson once a week (block-scheduled class). To assess the level of student learning success, all students underwent both an initial and final written exam in Nature and/or Biology, specific to each grade. The rmANOVA proved that there was a significant interaction among class scheduling, performance categories, and the initial and final written exam scores of fifth- and seventh-grade students. Such a correlation was not found among the sixth- and eighth-grade students. Our findings further indicate that students achieve better results in block-scheduled classes at the end of primary school education, and that block class scheduling does not necessarily result in improved student achievement, particularly in lower-performing students.

Teaching wireless networking fundamentals is often difficult because many students appear to find the subject technical, and dry when presented in traditional lecture format. To overcome this problem, we provide an opportunity for experiential learning where students can learn wireless networking fundamentals by hands-on practical activities using low-cost Wi-Fi (wireless fidelity) devices such as wireless cards and access points. Students can easily set up and configure networks using wireless cards and access points more effectively. By measuring network performance such as throughput and end-to-end delays, students are able to gain a deeper understanding of wireless networking. The effectiveness of Wi-Fi-based practical activities has been evaluated by students and the teaching team. This chapter reports on the overall effectiveness of teaching and learning of wireless network using radially available low-cost Wi-Fi cards and access points.

Purpose: MyPlate is the current dietary guidance icon meant to communicate healthy eating patterns. The purpose of this study is to evaluate knowledge of MyPlate nutrition education messages among middle school students and its association with dietary intake and perceived diet quality. Design: Secondary analysis of cross-sectional data. Settings: Survey of eighth-grade students from 16 middle schools in California. Subjects: A total of 3521 eighth-grade students. Measures: MyPlate knowledge was assessed with 3 questions asking how much of the plate in a typical meal should be (1) fruits and vegetables, (2) grains, and (3) proteins. A brief food frequency questionnaire measured intake of fruits, vegetables, sweets, salty snacks, fast-food, and sugar-sweetened beverages (SSBs) over the past 7 days. Students self-rated their diet quality as poor, fair, good, or excellent. Analysis: Hierarchical logistic regression models controlling for gender, ethnicity, and socioeconomic status. Results: Only 11% of students answered all MyPlate questions correctly. MyPlate knowledge was associated with 65% higher odds of not consuming SSBs, but 46% lower odds of not consuming sweets. MyPlate knowledge was not associated with adolescents’ perceived diet quality or intake of salty snacks, fruits, or vegetables. Conclusion: Knowledge of nutrition education messages communicated by the MyPlate dietary guidance icon is limited among adolescents. The association between MyPlate knowledge and lower consumption of SSBs is encouraging, given the strong association between SSBs and childhood obesity.
