Three students were selected who met different logical thinking stages: the abstract operation stage, the transition stage, and the concrete operational stage. The results showed the subject of the abstract operation stage fulfilled the metacognition stage by re-describing the given problem, knowing the relationship between what was known and what was asked, working on the problem by writing down what was known and asked and entering into the formula and also checking the answer. Transition stage subjects fulfill the metacognition stage by describing initial information and instructions, performing problem-solving steps, and counting to check completed work. The subject of concrete operations fulfills the metacognition stage by stating information and instructions that are non-specific and detailed.

The purpose of this study is to find out how to adjust to adolescents who have to face the divorce of their parents, find out the impact of parental divorce for adolescents, and also understand how the psychological dynamics of the research subjects. The subjects in this study were two adolescents who fulfilled the predetermined research subject criteria, namely facing divorce from parents and taken with a purposive sampling technique. This study uses a qualitative phenomenological method. The results of this study indicate that all research subjects develop poor relationships outside the home, difficulty in getting along due to hampered social adjustment. Divorce of parents also raises a lot of anxiety and frustration in adolescents and reduce academic achievement in school. In addition, divorce that occurs in parents also makes children build feelings of being hurt, neglected, and betrayed by their parents. However, there seems to be a quite striking difference regarding the development of adjustment that occurs in each subject. One subject showed a better adjustment. This condition seems influenced by his ability to apply coping stress appropriately, namely trying to accept the divorce of parents and not thinking about the divorce (emotional focused coping). In addition, the parents of the subject also did not show conflict in front of their children despite the divorce. Keywords: Adjusment, Divorce of Parent, Adults   Tujuan penelitian ini adalah untuk menemukan bagaimana penyesuaian diri pada remaja yang harus menghadapi perceraian orang tuanya, mengetahui dampak dari perceraian orang tua bagi remaja, dan juga memahami bagaimana dinamika psikologis dari para subjek penelitian. Subjek dalam penelitian ini adalah dua remaja yang memenuhi kriteria subjek penelitian yang telah ditentukan yaitu menghadapi perceraian orang tua dan diambil dengan teknik purposive sampling. Penelitian ini menggunakan metode kualitatif fenomenologi. Hasil penelitian ini menunjukkan bahwa seluruh subjek penelitian mengembangkan hubungan yang buruk di luar rumah, kesulitan bergaul karena penyesuaian sosial yang terhambat. Perceraian orang tua juga memunculkan banyak kecemasan dan frustrasi pada diri remaja serta menurunkan prestasi akademik di sekolah. Selain itu, Perceraian yang terjadi pada orang tua juga membuat anak membangun perasaan telah disakiti, diabaikan, dan dikhianati oleh orang tua mereka. Namun demikian, tampak adanya perbedaan yang cukup mencolok mengenai perkembangan penyesuaian diri yang terjadi pada tiap subjek. Salah satu subjek memperlihatkan adanya penyesuaian diri yang lebih baik. Kondisi tersebut tampaknya dipengaruhi oleh kemampuannya menerapkan coping stress yang tepat yaitu berusaha menerima perceraian orang tua dan tidak memikirkan perceraian tersebut (emotional focused coping). Selain itu, kedua orang tua subjek tersebut juga tidak memperlihatkan konflik di hadapan anak mereka meskipun telah terjadi perceraian.   Kata Kunci: Penyesuaian Diri, Perceraian Orang tua, Remaja.

This study investigated three objectives: 1) to determine the effectiveness of a mathematics instructional package on Ploya’s steps including video clips to enhance problem solving abilities of 6th grade students in Bhutan, 2) to compare students’ mathematics problem-solving abilities before and after implementing the package by using a pretest and posttest, and 3) to examine students’ satisfaction level after learning with the mathematics instructional package. In the first semester of 2017, twenty-eight 6th grade students at Khamdang Lower Secondary School in Trashi Yangtse District in Bhutan were selected as the sample by employing the purposive sampling technique. The instruments used in this study were 1) the instructional package (lesson plans on Pólya’s steps with video clips), 2) problem-solving ability tests, and 3) questionnaires. The data were statistically analyzed to determine the effectiveness index (E.I), dependent sample t-test, mean and standard deviation. The results revealed that the effectiveness index of the lesson plans of the instructional package was higher than the set criteria of 0.50. The improvements in problem solving abilities of the students after implementing the instructional package were statistically significant (p<0.05). The students’ satisfaction level after implementation of the instructional package proved to be “very high”. In conclusion, the lesson plans on Pólya’s steps including video clips were determined to be an effective tool to increase 6th grade students’ mathematics problem-solving abilities.
