Data were collected at a large urban high school in order to determine the extent of discipline problems, the use of suspension, and the procedural integrity of the school's disciplinary policy. Results documented a high frequency of disciplinary referrals and suspensions and poor correspondence between school disciplinary policy and disciplinary actions. Next, individual assessments of middle and high school students' academic and social behavior documented a very high incidence of academic and social skills deficits, as well as other adjustment problems, among students with recurrent suspensions. Substantial individual differences between students illustrated that students with recurrent suspensions are a very heterogeneous group. Implications for developing proactive treatment alternatives to suspension are discussed.

Abstracts: What are Responses and Expectations of Senior High School Students to Blended Learning? The effectiveness of learning innovation could not ignore an important aspect of student’s characteristics. The purposes of this research were to (1) describe the response of high school (SMA) students towards learning chemistry delivered by blended learning (BL), and (2) to explore the expectations of students towards the online content and chemistry learning management deli-vered by BL. To obtain the responses and the expectations of students, 140 questionnaires distri-buted online to the grade nine of class XI MIA SMA students (respondents) in seven SMAin seven-regencies in Bali: SMAN 1 Gianyar, SMAN 1 Sidemen Karangasem, SMAN 2 Semarapura, SMAN 5 Denpasar, SMAN 1 Singaraja, SMAN 1 Kuta Utara, and SMAN 1 Kediri Tabanan. The result of the research shows that only 110 respondentscompleted a questionnaire of students responsesabout BL and 106 respondents completed questionnaires of students’ expectations towards online content and management of BL. SMA students gave a positive response to the application of BL and provi-ded important inputs which were useful fordeveloping online content and management of BL for se-nior high school students.Key Words: blended learning, chemistry instruction, online contentAbstrak: Apa Respons dan Harapan Siswa SMA tentang Blended Learning? Efektivitas suatu inovasi pembelajaran tidak bisa mengabaikan aspek penting karakteristik siswa. Tujuan penelitian ini adalah untuk (1) mendeskripsikan respons siswa SMA terhadap pembelajaran kimia yang di-sampaikan secara blended learning (BL), dan (2) menjaring harapan siswa terhadap konten dan pe-ngelolaan pembelajaran kimia yang disampaikan secara BL. Untuk memperoleh gambaran tentang respons dan harapan siswa tersebut, 140 angket disebarkan secara online ke siswa SMA kelas XI MIA yang tersebar di 7 SMA di 7 kabupaten/kodya di Bali, yaitu SMAN 1 Gianyar, SMAN 1 Side-men Karangasem, SMAN 2 Semarapura, SMAN 5 Denpasar, SMAN 1 Singaraja, SMAN 1 Kuta Utara, dan SMAN 1 Kediri Tabanan. Hasil penelitian menunjukkan bahwa hanya 110 siswa yang mengisi angket respos siswa terhadap BL dan 106 responden yang mengisi angket harapan siswa terhadap konten online dan pengelolaan BL. Siswa SMA memberikan respon yang positif terhadap penerapan BL dan memberikan masukan yang berguna untuk mengembangkan konten online dan pengelolaan BL untuk siswa SMA.Kata-kata Kunci: blended learning, konten online, pembelajaran kimia

The purpose of this study is to examine the effects of different ways to use visualizations on high school students’ electrochemistry conceptual understanding and motivation towards chemistry learning. Expanding upon a model-based learning approach (Khan, 2007), we adopted a VGEM sequence (View, Generate, Evaluate, and Modify) to create three instructional conditions. All conditions involved the viewing, evaluating, and modifying phases, whereas there were variations in the generating phase: (1) finishing worksheets (V group), (2) generating drawings (VD group), and (3) generating animations (VA group). Three intact classes with 109 eleventh graders from a public high school were randomly assigned to the three groups. A test of conceptual understanding was used as the pretest, posttest, and delayed posttest to assess respectively initial understanding, changes, and retention of understanding up to 6 weeks later. A questionnaire to measure students’ motivation to learn chemistry was administered before and after the instruction. Statistical results of the within-group comparisons revealed that all three instructional conditions could support students to develop a significantly better conceptual understanding of electrochemistry and that in the three groups, students’ understanding was retained after 6 weeks. Regarding the overall motivation before and after the instruction, only the VA group showed motivational benefits for chemistry learning. Furthermore, the between-group comparisons indicated no significant differences between the means of the three groups in the posttest and delayed posttest, and suggested that the three groups developed and retained a similar level of conceptual understanding after the instruction. Similarly, different uses of visualizations made no difference to students’ chemistry learning motivation. This study advances the understanding of how to develop effective instructional activities with visualizations for chemistry learning, and suggests possible conceptual and motivational benefits of viewing and generating visualizations.

This study aims to determine whether there is an influence on the implementation of PBL through a scientific approach that provides a media card for high school students' chemistry learning outcomes. To achieve this goal, quasi-experimental research was conducted using two classes, namely the experimental class and the control class. Data obtained using a validated test instrument in the form of pretest and posttest. The results showed that (1). There was an increase in chemistry learning outcomes from the average pretest 27.2 to 63.95 and 72.5 in the two classes of experiment I and experiment II, respectively. (2). Student learning outcomes that are taught with the Problem Based Learning model and the scientific approach provides higher paired cards than using textbook as a media.

This research aimed to develop The Better Energy Encyclopedia for Indonesia (BEEI) as a chemistry learning source for senior high school students and to determine the quality of the encyclopedia according to assessment of five chemistry teachers as reviewer based on quality criteria (standard) of non-text books include content/material, presentation, language and images, and graphics expediency. This research used model of procedural development including of five stages, they are planning, organizing, implementation, product assessment, and data analysis. The developed encyclopedia contains 15 chapters of renewable energy and non-renewable energy. The initial product was reviewed by three peer reviewers, a media expert, and a teaching materials expert. The final product was assessed by five reviewers of senior high school teachers from different school. Assesment was done by using research instrument sheet consisting 34 items statements. The result of this development research was the Better Energy Encyclopedia for Indonesia. This product obtained an average final score (x) of 149.20. According to the assessment result by five reviewers, this final product quality of encyclopedia obtained the excellent category. Thus, the Better Energy Encyclopedia for Indonesia is worthy of being used as a chemistry learning source for senior high school students.

The results of this research study with descriptive qualitative methods aim to analyze the findings related to the entrepreneurial spirit of high school students. The subjects in this study were 69 students of class XI involving 2 state high schools in Semarang in the academic year 2018/2019. Data collection is done by observation, questionnaires, and documentation. The results showed that 64.71% in SMA X had an entrepreneurial spirit with strong criteria and 35.29% with very strong criteria. In state high school Y 2.86% have an entrepreneurial spirit with weak criteria, 65.71% strong criteria and 31.43% very strong criteria. High school students tend to have an entrepreneurial spirit with strong criteria. But after being analyzed, the lowest score on the entrepreneurial spirit is the aspect of confidence. Various supports in learning can be done to improve the quality of learning and produce students who have good self-confidence. Steps that need to be taken include improving the method or model of learning and using teaching materials that support the growth of the entrepreneurial spirit, especially in the aspect of self-confidence.
